Answer:

The distance is:

d = 10.0 units (Rounded to the nearest the Tenths Place)

Step-by-step explanation:

Given the points

The distance 'd' between (3,4) and (4,-6)

\(\mathrm{Compute\:the\:distance\:between\:}\left(x_1,\:y_1\right),\:\left(x_2,\:y_2\right):\)

\(d=\sqrt{\left(x_2-x_1\right)^2+\left(y_2-y_1\right)^2}\)

substituting the points values

   \(=\sqrt{\left(4-3\right)^2+\left(-6-4\right)^2}\)

   \(=\sqrt{1+10^2}\)

   \(=\sqrt{1+100}\)

   \(=\sqrt{101}\)

   \(=10.0\)  units (Rounded to the nearest the Tenths Place)

Thus, the distance is:

The time that it will take for the shadow to travel 1150 miles is; 30 minutes

Let y represent the distance in miles    

Let x represent the time in minutes

The shadow travels 2300 miles in 1 hour or 60 minutes and in the first 20 minutes the shadow traveled 766 ²/₃ miles or 2300/3 miles

Thus, the coordinates are;

(60, 2300) and (20,  2300/3)

The slope is;

m = (2300 - 2300/3)/(60 - 20)

m = 115/3 mi/min

Thus, the linear equation in point slope form is;

y - 2300 = (115/3)(x - 60)

This gives;

y = (115/3)x

When y = 1150 miles, we have;

1150 = (115/3)x

x = 30 minutes

Step-by-step explanation:

multiply

Answer:

Step-by-step explanation:

1)  the equation would be:

(2x+4)x(5x+1) because if the amount of ballpens are (2x+4) and the ballpens are $(5x+1) each, you would multiply them.

this is the expanded version of (2x+4)(5x+1)
{10x^2 + 2x + 20x + 4

10x^2 + 22x + 4}

2) (x^2 +1)(x+2) are multiplied to find the volume of the box

So when expanded it looks like this:

{x^3 + 2x^2 + x + 2}

3) (15a^2b^3) would be multiplied with (2a). This is because to find the total you would times the numbers.
so when expanded:

(15a^2b^3)(2a)

{(15a^3)(2ab^3)}

4) 5X(x+8)=33

5x+40=33

5x=33-40

5x=-7

X= -7/5

5) x-8=8x

8x-x = -8

7x=-8

X=-8/7

Answer:8758125

Step-by-step explanation:

Answer:

The equation

\(4\,x^2-5=2\,(x+1)^2-7\)

can be solved by first expanding all indicated operations, and later when the constant terms disappear, by factoring out 2x , leaving the equation as a product of two factors equal zero, from which it is easy to extract the roots. See below.

Step-by-step explanation:

When solving for x in the following expression, and using factoring to apply at the end the zero product theorem:

\(4\,x^2-5=2\,(x+1)^2-7\\4\,x^2-5=2\,(x^2+2x+1)-7\\4\,x^2-5=2\,x^2+4\,x+2-7\\4\,x^2-5=2\.x^2+4\,x-5\\4\,x^2=2\,x^2+4\,x\\4\,x^2-2\,x^2-4\,x=0\\2\,x^2-4\,x=0\\2\,x\,(x-2)=0\)

We observe that for the last product, to get a zero, x has to be zero (making the first factor zero), or x has to be "2" making the binomial factor zero.

Solution

A=P×(1+rt)

Where:

A = Total amount

P = principal amount = $400

r = interest rate = 6 % =6/100 = 0.06

t = time period = x

Finance charge = $48

we will first divide the interest rate by 12 to find the monthly interest rate.

To find the number of years of paying

Time = 2 years

2 years = 2 x 12 = 24 month

(b) Now to find the monthly payment, we will simply divide the total amount payable by number of months.

Monthly payment

Monthly payment =

Therefore the monthly payment = $19

The equation of the parabola is h²-16h+8k+32=0 when parabola can be drawn with a focus of (8,10) and a directrix of y=6.

Given that,

A parabola can be drawn with a focus of (8,10) and a directrix of y=6.

We have to find the equation of the parabola in any form.

We know that,

The distance of any point P is (h,k) on a parabola form a focus is equal to its perpendicular distance from the directrix.

So,

√((h-8)²+(k-2)²) = | (k-6)/√0²+1² |

Squaring on both sides

(h-8)²+(k-2)² = (k-6)²

From th formula (a-b)² = a²-2ab+b²

We get,

h²-16h+64+k²-4k+4 = k²-12k+36

h²-16h+64+k²-4k+4 - k²+12k-36 =0

h²-16h+64-4k+4+12k-36=0

h²-16h+8k+32=0

Therefore, The equation of the parabola is h²-16h+8k+32=0 when parabola can be drawn with a focus of (8,10) and a directrix of y=6.

Answer:

Length = 18ft Height = 10ft

Explaination:

We know that the height of the model is 6 inches, and we know that 3in=5ft. To find the height of the real thing we need to find out how many times 3 can fit into 6 which is 2 times. Multiply 2 by 5 to get 10, which is the height for the real elephant.

To find the length, we follow the same steps. First find out how many times 3 fits into 10.8, which is 3.6 times. Then multiply 3.6 by 5 to find the height which is 18ft.

hope this helps!

The height and length of the actual elephant are 10 ft high and 18 ft long.

For a particular scale drawing, it is already specified that all the measurements' some constant scaled version will be taken. For example, let the scale be K feet to s inches.

Then it means

\(\rm 1\: ft : \dfrac{s}{k}\: in.\)

All feet measurements will then be multiplied by s/k to get the drawing's corresponding lengths.

The scale used for the drawing was 3 in to 5 ft

We know that one basic unit in the drawing is in fact 3 inches.

These factors need to be multiplied with the base units of 5 ft for reality.

6 inches high

6 / 3 = 2

Now the elephant is 2 units high, which means in reality

2×5 = 10 ft high.

10.8 inches long

10.8 / 3 = 3.6

Therefore, the elephant is 3.6 units long, which means 3.6×5 = 18 ft long.

Hence the height and length of the actual elephant are 10 ft high and 18 ft long.

Answer:

A. x+y=34

   10x+15y=410

Step-by-step explanation:

First the question states that babysitting is represented by x and yard work is represented by y, so that eliminates C and D.

If x and y are the amount of hours put into babysitting and yard work you would make the equation, x+y=34 to find out how many hours of each were worked.

Then you would make the equation 10x+15y=410 with the known variables.

So in conclusion A is the correct answer.

The cumulative probability of obtaining a sample result will be approximately 0.0001

We have to apply Formula of Binomial Distribution:

P(X ≤ 168) = ΣP(X = i) for i = 0, 1, 2, .., 168, here in a sample of size n, P(X = i) is the probability of getting exactly i success

We assume that company's claim is true, 0.8 is the probability of success for each trial

P(X = i) = (200 choose i)×\(0.8^{i}\) ×\(0.2^{200- i}\)

By using this, we can easily find that cumulative probability is 0.0001

So, the probability is very low, this means that company's claim of an 80% success rate can be incorrect

So, further analysis may be needed to draw some conclusions and results

A low standard deviation suggests that values are often close to the mean of the collection, whereas a large standard deviation suggests that values are dispersed over a wider range.

Standard deviation, often known as SD, is most frequently represented in mathematical texts and equations by the lower case Greek letter (sigma), for the population standard deviation, or the Latin letter s, for the sample standard deviation.

Let the scores be X and X is normally distributed with a mean of 22 and standard deviation of 2.

μ=22

Step-by-step explanation:

Answer:

y = 2x - 4

Step-by-step explanation:

To solve this problem, we must first calculate the slope of the line AB using the formula:

\(\boxed{m = \frac{y_2 - y_1}{x_2 - x_1}}\)

where:

m ⇒ slope of the line

(x₁, y₁), (x₂, y₂) ⇒ coordinates of two points on the line

Therefore, for line AB with points A = (2, 5) and B = (4, 4) :

\(m_{AB} = \frac{5 - 4}{2 - 4}\)

⇒ \(m_{AB} = \frac{1}{-2}\)

⇒ \(m_{AB} = -\frac{1}{2}\)

Next, we have to calculate the slope of the line BC.

We know that the product of the slopes of two perpendicular lines is -1.

Therefore:

\(m_{BC} \times m_{AB} = -1\)      [Since BC and AB are at right angles to each other]

⇒ \(m_{BC} \times -\frac{1}{2} = -1\)

⇒ \(m_{BC} = -1 \div -\frac{1}{2}\)      [Dividing both sides of the equation by -1/2]

⇒ \(m_{BC} = \bf 2\)

Next, we have to use the following formula to find the equation of line BC:

\(\boxed{y - y_1 = m(x - x_1)}\)

where (x₁, y₁) are the coordinates of a point on the line.

Point B = (4, 4) is on line BC, and its slope is 2. Therefore:

\(y - 4 =2 (x - 4)\)

⇒ \(y - 4 = 2x - 8\)         [Distributing 2 into the brackets]

⇒ \(y = 2x-4\)

Therefore, the equation of line BC is y = 2x - 4.

The probability of selecting a sample with a mean of 1450 or less, given a known population mean of 1500 and a known standard error of the mean of 42.50, is approximately 11.90%.

Probability plays a significant role in statistics and helps us understand the likelihood of an event occurring. In this case, we will discuss the probability of selecting a sample with a mean of 1450 or less, given a known population mean of 1500 and a known standard error of the mean of 42.50.

To calculate the probability of selecting a sample with a mean of 1450 or less, we will use the concept of the standard normal distribution. The standard normal distribution is a probability distribution that has a mean of 0 and a standard deviation of 1.

We can convert any normal distribution to a standard normal distribution by using the formula z = (x - μ) / σ, where z is the standard score, x is the raw score, μ is the population mean, and σ is the standard deviation.

In this case, we know the population mean is 1500, and the standard error of the mean is 42.50. The standard error of the mean is the standard deviation of the sample means, and we can calculate it using the formula σ/√n, where σ is the population standard deviation and n is the sample size. However, in this case, we already know the standard error of the mean.

Using the formula z = (x - μ) / σ, we can find the z-score for a sample mean of 1450:

z = (1450 - 1500) / 42.50

z = -1.18

We can then use a standard normal distribution table to find the probability of a z-score of -1.18 or less.

The probability of a z-score of -1.18 or less is 0.1190, or approximately 11.90%.

Therefore, the probability of selecting a sample with a mean of 1450 or less, given a known population mean of 1500 and a known standard error of the mean of 42.50, is approximately 11.90%.

This means that if we were to randomly select samples from the population, about 11.90% of them would have a mean of 1450 or less.
