x^10 / x^4

(fraction problem)

Answer: E

Step-by-step explanation:

remember that domain is x and range is y

people say "domain and range" and alphabetically, it is x and then y.

so domain and range. x and y. memorize this

the answer is E because y is the one that stays above -4

x is all real numbers according to the graph

just look at the graph and notice that the x values (the values on the left-to-right of the line, the horizontal line), are basically all the numbers.

but not the y values. the y values are on the up-and-down line

Answer: E

Step-by-step explanation:

Since the Domain is X

The graph moves on forever in the x axis thus it is all real numbers.

The equation of the total cost for the cover charge and drinks in point-slope form is y = 6x + 5.

The point-slope form of a linear equation is given by -

 \(y - y_1 = m(x- x_1)\)

where m is the slope and \((x_1, y_1)\) is a point on the line.

Here, the total cost for the cover charge and drinks can be represented by the equation y = mx + b, where y is the total cost, x is the number of drinks, m is the cost per drink, and b is the cost of the cover charge.

We know that the cover charge is $5 and drinks are $6 each, so, we can find the slope (m) of the equation by using the cost per drink which is m = 6.

We can also find the point \((x_1, y_1)\) by using the cover charge cost which is (0,5).

Therefore, the equation in point-slope form of the total cost for the cover charge and drinks will be -

y - 5 = 6(x-0)

y - 5 = 6x

y = 6x + 5

Where x is the number of drinks and y is the total cost i.e. cover charge + drinks.

Answer:

27/50

Step-by-step explanation:

54 is another way of writing 54 hundredths, or as a fraction, 54/100. Asking for a simplified fraction is asking you to reduce the numerator and denominator by any common terms. 54 and 100 are both divisible by 2, so we get to 27/50. These have no factors in common, so 27/50 is our simplified fraction.

C. -3/4

Step-by-step explanation:

Answer:

-3/4

Step-by-step explanation:

You could identify two points and used the slope formula given two points.

OR

You can just count from one point to another.

First step: Identify two points where the line crosses nicely.

I see one at the y-intercept (0,1) and another at (4,-2). So starting at the y-intercept, how much do we need to travel down to get to (4,-2).  Hopefully you say down 3, so the rise is -3.  Now how much to the right after traveling down 3 from (0,1) to we need to travel to get to (4,-2) .  Count the spaces...4 units right so the run is 4.

The slope is -3/4

The linear function for this problem is defined as follows:

y = x + 50.

The slope-intercept equation for a linear function is presented as follows:

y = mx + b

In which:

The graph touches the y-axis at y = 50, hence the intercept b is given as follows:

b = 50.

When x increases by 10, y also increases by 10, hence the slope m is given as follows:

m = 10/10

m = 1.

Hence the function is given as follows:

y = x + 50.

The percentage change in the bond's price using the duration concept is approximately 0.03645, or 3.645%.

To calculate the percentage change in the bond's price using the duration concept, we can use the following formula:

Percentage Change in Bond Price = - (Duration * Change in Yield)

Given:

Duration = 7.29 years

Change in Yield = -0.005 (50 basis points decrease)

Using the formula, we can calculate the percentage change in the bond's price:

Percentage Change in Bond Price = - (7.29 * (-0.005))

Percentage Change in Bond Price = 0.03645

Therefore, the percentage change in the bond's price using the duration concept is approximately 0.03645, or 3.645%.

Perform a two-sample z-test for proportions to test if the proportion of college-age Massachusetts residents who support the legalization of recreational marijuana exceeds the proportion of college-age Rhode Island residents who support the legalization of recreational marijuana.

We are comparing two independent proportions, so we need to perform a two-sample z-test for proportions.

Let p1 be the proportion of college-age Rhode Island residents who support the legalization of recreational marijuana, and p2 be the proportion of college-age Massachusetts residents who support the legalization of recreational marijuana.

The null hypothesis is that the proportion of college-age Massachusetts residents who support the legalization is less than or equal to the proportion of college-age Rhode Island residents who support the legalization:

H0: p2 <= p1

The alternative hypothesis is that the proportion of college-age Massachusetts residents who support the legalization is greater than the proportion of college-age Rhode Island residents who support the legalization:

Ha: p2 > p1

We can use the pooled proportion to estimate the common proportion for both groups:

p = (x1 + x2) / (n1 + n2)

where x1 and x2 are the number of supporters in each group, and n1 and n2 are the sample sizes.

The test statistic is calculated as:

z = (p2 - p1) / sqrt(p*(1-p)*(1/n1 + 1/n2))

Under the null hypothesis, the test statistic follows a standard normal distribution.

Using the given values, we have:

p1 = 183/300 = 0.61

n1 = 300

p2 = 238/350 = 0.68

n2 = 350

p = (183 + 238) / (300 + 350) = 0.644

Plugging in these values, we get:

z = (0.68 - 0.61) / sqrt(0.644*(1-0.644)*(1/300 + 1/350)) = 2.33

Using a standard normal distribution table, the p-value is approximately 0.01.

Since the p-value is less than the significance level of 0.05, we reject the null hypothesis and conclude that the proportion of college-age Massachusetts residents who support the legalization of recreational marijuana is significantly greater than the proportion of college-age Rhode Island residents who support the legalization.

Therefore, we have evidence to suggest that the legalization of recreational marijuana is more supported among college-age Massachusetts residents compared to college-age Rhode Island residents.

In 15 years she would be 20

And 20 is 4 times as 5 which Is her current age

So Lisa is 5 years old now.

The probability that the child exhibits the disease is 18.75%

To determine the probability that the child exhibits the disease, we need to first find the probability of the child inheriting the disease-causing genotype and then multiply it by the penetrance of the disease.

Step 1: Determine the genotype probabilities
Since both parents are heterozygotes, their genotypes are Gg. Using a Punnett square, we can determine the probabilities of the child's possible genotypes:

Parent 1: G | g
Parent 2: G | GG | Gg
           g | Gg | gg

The child's possible genotypes and their probabilities are:
- GG: 1/4 (25%)
- Gg: 1/2 (50%)
- gg: 1/4 (25%)

Step 2: Determine the probability of the child exhibiting the disease
The disease is caused by homozygosity for the g allele, meaning the child must have the gg genotype to potentially have the disease. The probability of the child inheriting the gg genotype is 1/4 (25%).

Step 3: Factor in the penetrance of the disease
Since the penetrance of the disease is 75%, this means that 75% of individuals with the gg genotype will exhibit the disease. To find the probability of the child exhibiting the disease, multiply the probability of inheriting the gg genotype (1/4) by the penetrance (75%):

(1/4) * (75%) = 0.25 * 0.75 = 0.1875

Therefore, the probability that the child exhibits the disease is 18.75%.

There are three possible 1-digit ternary sequences

There are eight possible 2-digit ternary sequences

f(n) be the number of n-digit ternary sequences in which no 1 appears anywhere to the right of any 2. We can find a recursive formula for f(n)as follows:

Consider any such n-digit sequence. There are two cases to consider for the leftmost digit:

The leftmost digit is 0: In this case, we can append any valid (n-1)-digit sequence to the right, which gives us f(n-1)possibilities.

The leftmost digit is 2: In this case: f(n)=f(n−1)+f(n−2)as the second digit must be 0 (since no 1 can appear to the right of any 2). After the second digit, we can append any valid (n-2)-digit sequence to the right, which gives us\($f(n-2)$\) possibilities.

Therefore, we have the recurrence r

with initial values f(1) = 3(since there are three possible 1-digit ternary sequences: 0, 1, or 2) and f(2) = 8 (since there are eight possible 2-digit ternary sequences: 00, 01, 02, 20, 21, 22, 10, 12).

A recurrence relation is an equation which represents a sequence based on some rule. It helps in finding the subsequent term (next term) dependent upon the preceding term (previous term). If we know the previous term in a given series, then we can easily determine the next term.

Answer:

The height from ground, at which Jeb needs to hit the ball is 7.8 meters

Step-by-step explanation:

The given parameters are;

The distance away the tennis ball is hit = 20 meters;

The height of the tennis net = 0.3 m

The distance from the net the ball lands = 4 meters

The time the ball takes to land from the 0.3 m net height is given as follows;

t = √(h/(1/2×g)) = √(0.3/(1/2 × 9.8)) ≈ 0.2474

t ≈ 0.2474 seconds

The speed of the ball = Distance/Time = 4/0.2474 ≈ 16.166

The speed of the ball ≈ 16.166 m/s

The time it takes the ball to reach the net = 20/16.166 ≈ 1.24

The time it takes the ball to reach the net, tₓ ≈ 1.24 seconds

The height, hₓ the ball falls in 1.24 seconds is given as follows;

hₓ = 1/2·g·tₓ² = 1/2 × 9.8 × 1.24² = 7.5

The height, hₓ the ball falls in 1.24 seconds = 7.5 m

The height the ball falls in the time taken to reach the net from 20 meters = The height, hₓ the ball falls in 1.24 seconds

Therefore, the height at which Jeb needs to hit the ball = The height the ball falls in the time taken to reach the net from 20 meters + The height of the net = 7.5 m + 0.3 m = 7.8 m

The height at which Jeb needs to hit the ball = 7.8 m

The value of the union of sets A and B is, P(A ∪ B) is 0.64.

The union of two sets means the total elements in both the sets combined.

Given: sets P(A) = 0.38, P(B) = 0.83, and  intersection P(A ∩ B) = 0.57

We need to find the union of P(A ∪ B).

P(A ∪ B) = P(A) + P(B) - P(A ∩ B)

Let us substitute the given values in the formula.

P(A ∪ B) = P(A) + P(B) - P(A ∩ B)

=0.38+0.83-0.57

=1.21-0.57

=0.64

Therefore, the value of union of sets P(A ∪ B) is 0.64.
