Answer: 25

Step-by-step explanation: He scored 25 in the game

According to the question the fraction of the bigger square that is shaded is 50%.

Fraction is a numerical representation of a part of a whole or a ratio between two numbers. It is written in the form of a/b where a is the numerator and b is the denominator. A fraction can refer to a part of a whole number, a part of a set, or a part of a unit. Fractions are commonly used in mathematics, cooking, science, and many other areas.

This is because the ratio of the area of the smaller square to the area of the bigger square to the area of the triangle is 1:3:2. Therefore, the ratio of the area of the shaded parts of the squares to the area of the shaded triangle is 25%: 25%:50%. Since the area of the bigger square is three times that of the smaller square, then 50% of the bigger square must be shaded to maintain the given ratio.

Since the mean height of all children this age is 38 inches, the z-score is 1.282, and the child's height is 40 inches, the standard deviation of all children's heights will be 1561.

The standard deviation is a statistic that expresses how much variance or dispersion there is in a group of numbers. While a high standard deviation suggests that the values are dispersed throughout a larger range, a low standard deviation suggests that the values tend to be near to the established mean. The term "standard deviation" (or "") refers to a measurement of the data's dispersion from the mean. A low standard deviation indicates that the data are grouped around the mean, whereas a high standard deviation shows that the data are more dispersed.

Here,

The z-score which separates the top 10% of a normally distributed

population is 1.282.

Since z = (x-u)/sigma

1.282 = (40-38)/sigma

sigma = 2/1.282

sigma = 1/0.641 = 1561

The standard deviation of the heights of all children of this age will be 1561 as mean is 38 inch and z-score is 1.282 as well as the height of child is 40 inch.

Step-by-step explanation:

We are to prove that for any arbitrary integer a, 2 | a(a+1) and 3 | a(a+1)(a+2).

We will use the fact that for any integer n, either n is even or n is odd. So, we have two cases:

Case 1: When a is even

When a is even, we can write a = 2k for some integer k. Thus, a+1 = 2k+1 which is odd. So, 2 divides a and 2 does not divide a+1. Therefore, 2 divides a(a+1).

Case 2: When a is odd

When a is odd, we can write a = 2k+1 for some integer k. Thus, a+1 = 2k+2 = 2(k+1) which is even. So, 2 divides a+1 and 2 does not divide a. Therefore, 2 divides a(a+1).Now, we will prove that 3 divides a(a+1)(a+2).

For this, we will use the fact that for any integer n, either n is a multiple of 3, or n+1 is a multiple of 3, or n+2 is a multiple of 3.

Case 1: When a is a multiple of 3When a is a multiple of 3, we can write a = 3k for some integer k. Thus, a+1 = 3k+1 and a+2 = 3k+2. So, 3 divides a, a+1, and a+2. Therefore, 3 divides a(a+1)(a+2).

Case 2: When a+1 is a multiple of 3When a+1 is a multiple of 3, we can write a+1 = 3k for some integer k. Thus, a = 3k-1 and a+2 = 3k+1. So, 3 divides a, a+1, and a+2. Therefore, 3 divides a(a+1)(a+2).

Case 3: When a+2 is a multiple of 3When a+2 is a multiple of 3, we can write a+2 = 3k for some integer k. Thus, a = 3k-2 and a+1 = 3k-1. So, 3 divides a, a+1, and a+2.

Therefore, 3 divides a(a+1)(a+2).Hence, we have proved that for any arbitrary integer a, 2 | a(a+1) and 3 | a(a+1)(a+2).

Answer:

The value of y cannot be determined without additional information.

Step-by-step explanation: In the given expression, we have (3y + 53) and (7y - 55)°. Without any further context or equations, we cannot determine the value of y. In order to find the value of y, we need additional information or equations that relate to the given expressions.

The expression (3y + 53) does not involve any angles, so there is no direct connection to angle properties. Similarly, the expression (7y - 55)° represents an angle, but it alone does not provide enough information to determine the value of y.

To find the value of y and justify it using angle properties, we would need additional equations or relationships involving angles or variables that connect to (3y + 53) and (7y - 55)°. Without such information, we cannot determine the value of y.

Step-by-step explanation:

Larval mosquitoes breath through trachea in their siphons. This is a structure analogous to the snorkel on a diesel electric submarine. It allows for gas exchange with the atmosphere while the remainder of the insect is submerged. The opening of the siphon is hydrophobic so it won’t get wet and blocked by water. This works well to keep the siphon and the trachea open under normal conditions. Oil when poured on water forms a thin film. When there are mosquitos in that water, when their siphons contact the oil layer, the oil wets and blocks their siphons and suffocates the mosquitoes. This works against most, but not all mossies, as evolution is an amazing process. Some mosquitoes (Mansonia, Coquilletidia) have a siphon designed to penetrate the air vessels in aquatic plants and they don’t need to come to the surface to breath like other mossies. So oil won’t work on these genera.

The minimum stopping distance is 800 ft.

Part A: The minimum stopping distance for a driver going at the speed limit (40 mph) is given by the equation: s = v2/2a, where s is the stopping distance, v is the speed (40 mph), and a is the deceleration rate (assumed to be 10 ft/s2). Therefore, the minimum stopping distance is 800 ft.

Part B: For a driver going at 45 mph, the minimum stopping distance is given by the equation: s = v2/2a, where s is the stopping distance, v is the speed (45 mph), and a is the deceleration rate (assumed to be 10 ft/s2). Therefore, the minimum stopping distance is 925 ft, which is 15.6% greater than the stopping distance for the speed limit.

Part C: For a driver going at 50 mph, the minimum stopping distance is given by the equation: s = v2/2a, where s is the stopping distance, v is the speed (50 mph), and a is the deceleration rate (assumed to be 10 ft/s2).

The probability that you need to pick 7 students to find 2 students using Chrome is approximately 65%.

To calculate this, we can use the formula P = (n!/r!(n-r)!) * p^r * q^(n-r), where n = 7 (number of students to pick), r = 2 (number of Chrome users to find), p = 0.49 (probability of Chrome user), and q = 0.51 (probability of non-Chrome user). By plugging the numbers into the equation, the probability of finding 2 Chrome users is 0.649.

In other words, if you randomly pick 7 students from the group, there is a 65% chance that you will find 2 students using Chrome.

This is because 49% of the group use Chrome, so if you pick 7 students randomly, the probability of picking 2 Chrome users is high.

Answer:

length = 20 feet

Step-by-step explanation:

the area (A) of a rectangle is calculated as

A = length × width

let width be w , then length is 4w

given A = 100 , then

4w × w = 100

4w² = 100 ( divide both sides by 4 )

w² = 25 ( take square root of both sides )

\(\sqrt{w^2}\) = \(\sqrt{25}\)

w = 5

width = 5 feet and length = 4 × 5 = 20 feet

The probability that a randomly selected firm will earn between 9191 and 9797 million dollars is, 0.1879

We have to given that,

The mean income of firms in the industry for a year is 8585 million dollars with a standard deviation of 99 million dollars.

Hence, We need to standardize the values of 9191 and 9797 to a standard normal distribution with a mean of 0 and a standard deviation of 1. We can do this using the z-score formula:

z = (x - μ) / σ

where x is the value we want to standardize, μ is the mean of the distribution, and σ is the standard deviation of the distribution.

For x = 9191:

z = (9191 - 8585) / 99 = 0.61

For x = 9797:

z = (9797 - 8585) / 99 = 1.22

Now, we need to find the probability that a randomly selected firm will have an income between 9191 and 9797 million dollars.

This is equivalent to finding the area under the standard normal distribution curve between z = 0.61 and z = 1.22.

We can use a standard normal distribution table or calculator to find this probability.

For example, using a standard normal distribution table, we can find that:

P(0.61 < Z < 1.22) = 0.1879

Therefore, the probability that a randomly selected firm will earn between 9191 and 9797 million dollars is, 0.1879 or 18.79%.

The best description of the probability of drawing a king from the deck is 1 out of 13, or 1/13.

The probability of drawing a king from a standard deck of 52 playing cards can be determined by dividing the number of favorable outcomes (number of kings) by the total number of possible outcomes (total number of cards in the deck).

In a standard deck, there are 4 kings (one king for each suit: hearts, diamonds, clubs, and spades). Therefore, the number of favorable outcomes is 4.

The total number of possible outcomes is 52 (the total number of cards in the deck).

So, the probability of drawing a king is:

Probability = Number of favorable outcomes / Total number of possible outcomes

Probability = 4 / 52

Step-by-step explanation:

The future value (A) is approximately 5610.2 for the given investment and annu $4000 for 5 years at 7% compounded annually

To find the compound amount and compound interest rate for the given investment, we can use the formula for compound interest:

(a) The compound amount in the account after 5 years can be calculated using the formula:

A = P(1 + r/n)^(nt)

Where A is the compound amount, P is the principal (initial investment), r is the interest rate, n is the number of times the interest is compounded per year, and t is the number of years.

Given that the principal (P) is $4000, the interest rate ® is 7%, and the interest is compounded annually (n = 1), and the investment is for 5 years (t = 5), we can plug these values into the formula:

A = 4000(1 + 0.07/1)^(1*5)

A = 4000(1 + 0.07/1)^(1*5)

= 4000(1 + 0.07)^(5)

= 4000(1.07)^(5)

≈ 4000(1.402551)

≈ 5610.20

Therefore, the future value (A) is approximately 5610.2

Calculating this expression will give us the compound amount after 5 years.

(b) The compound interest earned can be calculated by subtracting the principal from the compound amount:

Compound interest = Compound amount – Principa

This will give us the total interest earned over the 5-year period.

By evaluating the expressions in (a) and (b), we can determine the compound amount and the compound interest earned for the given investment.

b) The probability P(z > 38.3333), which is virtually zero.

c) The probability P(z < 18.3333), which is virtually one.

d) P(7883.5) is not a valid probability

(a) The sampling distribution of x, the sample mean, can be approximated to be approximately normally distributed.

According to the central limit theorem, for a sufficiently large sample size, the distribution of the sample mean becomes approximately normal regardless of the shape of the population distribution.

In this case, since the sample size is 81, it meets the condition for the central limit theorem.

The standard deviation of the sampling distribution (also known as the standard error) can be calculated by dividing the population standard deviation by the square root of the sample size. In this case, the sample size is 81.

The standard deviation of the sampling distribution (σx) = σ / \(\sqrt(n)\)

= 18 / \(\sqrt(81)\)

≈ 2

Therefore, the value of the sampling distribution of x is approximately equal to 81, and the standard deviation is approximately 2.

(b) To calculate P(x > 835), we need to convert the sample mean to a z-score and then find the corresponding probability from the standard normal distribution table or using a calculator. The formula for calculating the z-score is:

z = (x - μ) / (σ /\(\sqrt(n)\))

where x is the value of interest, μ is the population mean, σ is the population standard deviation, and n is the sample size. Plugging in the values:

z = (835 - 81) / (18 / \(\sqrt(81)\)) ≈ 38.3333

Using a standard normal distribution table or calculator, we can find the probability P(z > 38.3333), which is virtually zero.

(c) To calculate P(x < 576.1), we again need to convert the sample mean to a z-score and find the corresponding probability. Using the same formula as in part (b):

z = (576.1 - 81) / (18 / \(\sqrt(81)\)) ≈ 18.3333

Using a standard normal distribution table or calculator, we can find the probability P(z < 18.3333), which is virtually one.

(d) P(7883.5) is not a valid probability as it refers to a specific value and not a range. Probabilities are typically calculated for a range of values.

The probability that the pooled sample variance, S2p, is less than 6.9157 is given by:

P(S2p < 6.9157) = P(S2p - S20 < 6.9157 - S20)

where S20 = ((n1-1)S21 + (n2-1)S22)/(n1+n2-2)



Here, n1 = 10 and n2 = 11. The individual sample variances S21 and S22 are both equal to 4, since both X and Y are samples from N(μ, 4).


Therefore, S20 = ((10-1)4 + (11-1)4)/(10+11-2) = 4.


Hence, P(S2p < 6.9157) = P(S2p - 4 < 6.9157 - 4) = P(S2p - 4 < 2.9157)

The Probability P(Sp² ​<6.9157) is 0.6672.

To solve this problem, we need to first recognize that the statistic Sp² follows a chi-squared distribution with 10+11-2 = 19 degrees of freedom, where:

Sp² = [(nX-1)*SX² + (nY-1)*SY²]/(nX+nY-2)

Here, nX = 10, nY = 11, SX² is the sample variance of X and SY² is the sample variance of Y.

Since X and Y are both normally distributed, we know that the sample variances SX² and SY² follow chi-squared distributions with 9 and 10 degrees of freedom, respectively, and scaled by the common variance sigma² = 4.

So we have:

SX² ~ chi-squared(9)*4 = chi-squared(36)

SY² ~ chi-squared(10)*4 = chi-squared(40)

Now we can use the fact that the sum of two independent chi-squared random variables with k1 and k2 degrees of freedom follows a chi-squared distribution with k1+k2 degrees of freedom.

Therefore, Sp² = [(nX-1)*SX² + (nY-1)*SY²]/(nX+nY-2) follows a chi-squared distribution with 9+10 = 19 degrees of freedom and scale parameter 4/(nX+nY-2) = 4/19.

To find P(Sp² < 6.9157), we can use a chi-squared distribution table or calculator. Using a chi-squared calculator, we find:

P(Sp² < 6.9157) = 0.6672

Therefore, the probability that Sp² is less than 6.9157 is 0.6672.
