Answer:

A. [tex]G(x) = 7x^2[/tex]

D. No, because one x-value corresponds to two different y-values.

Step-by-step explanation:

If you were to vertically stretch the quadratic parent function, the correct answer would be "A," because you are stretching upwards, which in turn, also changes the y-values.

As you can see in the table, the x-value of 3 repeats, which cannot occur. Each input (x-value) can go to only one output (y-value). As a result, the table does not represent a function.

Answer: the numbers are 5,111.3 and 35.74

Step-by-step explanation:

I will answer this in English.

We have the numbers X and Y, ad we have that:

X + 2*Y^2 = 7776

X = 7776 -  2*Y^2

Now we also want that the product of X and Y is a maximum.

The equation of maximum product is

P(Y) = X*Y = (7776 -  2*Y^2)*Y

       = 7776*Y - 2*Y^3

Now, to find the maximum we must derivate and find the value where P'(Y) is equal to 0

P'(Y) = 7776 - 6*Y^2 = 0

7776 = 6*Y^2

Y = √(7776/6) = 35.74

Now, we replace this value in the equation for X and we can find X:

X = 7776 -  2*Y^2  = X = 7776 -  2*(35.74)^2 = 5,111.3

Answer: what is the question?

Step-by-step explanation:

Answer:

x = 5; y = 138, z= 42

Step-by-step explanation:

4x- 17 = 3 [ opposite sides of a parallelogram are equal]

4x = 3+ 17 = 20; X= 20/4 = 5

138 + Z = 180( angle on a straight line)

Z is an alternate angles to the remaining angle off 138 forming the straight line.

z= 180-138 = 42 degrees

Y = 138 [ opposite angles of a regular quadilareral been equal]

Answer:

a = 250 ; b = 10

Step-by-step explanation:

a = 5 × 10² / 2

a = 5 × 100 / 2

a = 500 / 2

a = 250

b = 2 × 10² (10-5) / 10×10

b = 2 × 100 × 5 / 100

b = 1000 / 100

b = 10

Answer:

With replacement, 0.037, independent

Without replacement, 0.031, dependent

Step-by-step explanation:

There are 5 vowels (not including y).

The probability the first letter is a vowel is 5/26.

With replacement, the probability the second letter is a vowel is also 5/26.

The total probability is (5/26) (5/26) = 0.037.

Since the first letter is replaced, the probability of the second letter is not affected, so the events are independent.

Without replacement, the probability the second letter is a vowel is 4/25.

The total probability is (5/26) (4/25) = 0.031.

Since the first letter is not replaced, the probability of the second letter is affected, so the events are dependent.

Answer:

(1) Alternate Hypothesis.

(2) Null Hypothesis.

(3) Alternate Hypothesis.

(4) Null Hypothesis.

(5) Alternate Hypothesis.

Step-by-step explanation:

A null hypothesis is a sort of hypothesis used in statistics that intends that no statistical significance exists in a set of given observations.  

It is a hypothesis of no difference.

It is typically the hypothesis a scientist or experimenter will attempt to refute or discard. It is denoted by H₀.

Whereas, the alternate hypothesis is the contradicting statement to the null hypothesis.

The alternate hypothesis describes direction of the hypothesis test, i.e. if the test is left tailed, right tailed or two tailed.

It is also known as the research hypothesis and is denoted by Hₐ.

(1)

The hypothesis statement is:

"The number of hours that grade-school children spend doing homework predicts their future success on standardized tests."

According to the hypothesis statement, we known that the test to be performed is for the relationship between the number of hours that grade-school children spend doing homework and their future success on standardized tests.

So, the null hypothesis here will be that there is no relation between the two variables, or the number of hours that grade-school children spend doing homework does not predicts their future success on standardized tests.

Thus, the provided statement is a Alternate hypothesis.

(2)

The hypothesis statement is:

"King cheetahs on average run the same speed as standard spotted cheetahs."

According to the hypothesis statement, we known that the test to be performed is for the difference between the mean running speed of king cheetahs and spotted cheetahs.

The statement provided is a statement of no difference, i.e. there is no difference between the mean running speed of king cheetahs and spotted cheetahs.

Thus, the provided statement is a Null hypothesis.

(3)

The hypothesis statement is:

"The mean length of African elephant tusks has changed over the last 100 years."

According to the hypothesis statement, we known that the test to be performed is for the significance of single mean.

The null hypothesis here would be there is no change in the mean length of African elephant tusks over the last 100 years.

Thus, the provided statement is a Alternate hypothesis.

(4)

The hypothesis statement is:

"The risk of facial clefts is equal for babies born to mothers who take folic acid supplements compared with those born to mothers who do not."

According to the hypothesis statement, we known that the test to be performed is for the difference between the proportion of risk of facial clefts for babies born to mothers who take folic acid supplements and with those born to mothers who do not.

The null hypothesis here would be that there is no difference between the two risk proportions.

Thus, the provided statement is a Null hypothesis.

(5)

The hypothesis statement is:

"Caffeine intake during pregnancy affects mean birth weight."

According to the hypothesis statement, we known that the test to be performed is for the significance of single mean.

The null hypothesis of this test will be that the mean birth weight is not affected by the caffeine intake during pregnancy.

Thus, the provided statement is a Alternate hypothesis.

Answer:

Use interval estimation to compute the average weight of fish living in a large pond.

Step-by-step explanation:

In statistic, point estimation comprises of the use of sample data to estimate a distinct data value (known as a point estimate) which is to function as a "best guess" or "best estimate" of an unidentified population parameter.  

The point estimate of the population mean (µ) is the sample mean ([tex]\bar x[/tex]).

Now according to the law of large numbers, in probability concept, states that as we increase the sample size, the mean of the sample ([tex]\bar x[/tex]) approaches the whole population mean (µ).

That is, [tex]\bar x[/tex] →  µ as n → ∞.

The scientist uses the weights of 25 fish from the pond to find the average weight.

The sample is large, but not large enough.

So, use interval estimation to compute the average weight of fish living in a large pond.

The interval estimation is the best way to estimate the true value of a parameter. This is because the interval of values computed for the parameter has certain probability of containing the true parameter value.

The (1 - α)% confidence interval for population mean is an interval estimate.

Answer:

905

Step-by-step explanation:

So your original equation is f(x) = x² + 5

First lets work with the stuff inside the parentheses.

f(5) = 5² + 5 = 30

So now you are finding,

f(f(5)) => f(30)

f(30) = 30² + 5 = 900 + 5 = 905

Answer:

Amount of crimson velvet left = 3200 -  120 - 1400 = 1680  cm

Step-by-step explanation:

The arts and craft shop has a bolt of crimson velvet of 32 meters long. A customer bought 120 centimetres of the velvet. In the afternoon another customer bought 14 meters. The remaining length of crimson velvet Malik shop possess after the morning and afternoon sales can be calculated below.

The total length of the crimson velvet = 32 meters. Since our answer should be in centimetre we will convert all the units to cm.

total length = 32 m

1 m = 100 cm

32 m = ?

cross multiply

total length in cm = 32 × 100 = 3200 cm

The first customer bought 120 cm

The second customer bought 14 m so let convert again.

1 m = 100 cm

14 m = ?

cross multiply

the second customer length in cm = 14 × 100 = 1400 cm

The amount left in the shop will be as follows

Amount of crimson velvet left = 3200 -  120 - 1400 = 1680  cm

So the value of h and r are both 1 inch

Step-by-step explanation:

Volume of a cylinder = πr²h

Volume of the cylinder = 3.14 ft³

And π = 3.14

Dividingthrough by π

r²h = ft³

So the possible out come of r and h is only one because r² must be equal to one and the product of the two must be equal to one.

So the value of h and r are both 1 inch

Answer:3 ft

Step-by-step explanation:

Answer:

Area = base × height

31.5 = base × 6.3

base = 5 ft

Answer:

5 feet

Step-by-step explanation:

The area formula is A = b * h, where A is the area, b is the length of the base, and h is the height. Since we want to know the length of the base, we are solving for b. Thankfully, we know that A = 31.5 and h = 6.3. When we plug them into the equation, we get 31.5 = b * 6.3. Because we want b on one side without any coefficients and numbers on the other side, we can divide the equation by 6.3 on both sides. The equation will remain the same because we are doing the same thing to both sides. When we divide, we get b = 31.5 / 6.3 = 5 feet. Hope this helps!

Answer:

The equivalent expression is: (6x + 5)*(6x - 5)

Step-by-step explanation:

This expression is called the difference of two squares.

It has the following format: [tex]a^{2} - b^{2}[/tex]

It is factored as: [tex]a^{2} - b^{2} = (a-b)*(a+b)[/tex]

In this question:

[tex]a^{2} - b^{2} = 36x^{2} - 25[/tex]

So

[tex]a^{2} = 36x^{2}[/tex], then [tex]a = \sqrt{36x^{2}} = 6x[/tex]

[tex]b^{2} = 25[/tex], then [tex]b = \sqrt{25} = 5[/tex]

So

The equivalent expression is: (6x + 5)*(6x - 5)
