Answer:

Step-by-step explanation:

In each case, put the function argument where the variable is and do the arithmetic (or algebra).

a) f(-9) = 3(-9)^2 -2(-9) = 3·81 +18 = 261

__

b) g(-3) = -8(-3)-(-3) = 24 +3 = 27

__

c) f(p+4) = 3(p+4)^2 -2(p+4)

  = 3(p^2 +8p +16) -2p -8

  = 3p^2 +22p +40

_____

Additional comment

The form of g(x) is unusual, leading us to suspect it might be ...

   g(x) = -8x^2 -x

In that case,

  g(-3) = -8(-3)^2 -(-3) = -8·9 +3 = -69

Answer:

H₀: µ = 1100 vs. Hₐ: µ ≠ 1100.

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.

For instance, H₀: µ = µ₀, where µ₀ is some null value or some claimed value.

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.

In this case the hypothesis can be defined as follows:

Null hypothesis:

H₀: The average calorie intake of a diner at this restaurant is 1100, i.e. µ = 1100.

Alternate hypothesis:

Hₐ: The average calorie intake of a diner at this restaurant is different from 1100, i.e. µ ≠ 1100.

The correlation coefficient measures the relationship between the two variables

The correlation coefficient is 0.234

The formula of correlation coefficient is:

[tex]r = \frac{1}{n - 1} * \sum{(\frac{x - \bar x}{\sigma_x})*(\frac{y - \bar y}{\sigma_y})[/tex]

Using the dataset from the complete question, we have:

[tex]r = \frac{1}{5 - 1} * 0.9375[/tex]

Evaluate the difference

[tex]r = \frac{1}{4} * 0.9375[/tex]

Evaluate the quotient

[tex]r = 0.234375[/tex]

Approximate

[tex]r = 0.234[/tex]

Hence, the correlation coefficient is 0.234

The numbers of can required to fill the mixture is 10 cans

Data;

To find the numbers of can required to fill the mixture, let's add the volume of the mixture.

volume of mixture = volume of water + volume of milk

volume of mixture = [tex]2 + 4.5 = 6.5L[/tex]

The entire volume of the mixture is 6.5L.

To find the numbers of cans that'll fill the mixture, let us divide 6.5 by 0.65.

Number of can required = [tex]\frac{6.5}{0.65} = 10[/tex]

From the calculation above, we would need 10 cans to fill the mixture.

Answer:

There is not sufficient evidence to conclude that there exists significant difference in the birth weights of a mother's first child and second child at 10% level of significance.

Step-by-step explanation:

When our p-value exceeds level of significance then we fail to reject our null hypothesis. In this scenario we are investigating if there exists significant difference in the birth weights of a mother's first child and second child and our null hypothesis is there exists no significant difference in the birth weights of a mother's first child and second child i.e.μd=0.

As we are given that p-value is greater than 10% level of significant so, we cannot reject our null hypothesis. Thus, the conclusion statement can be written as "There is not sufficient evidence to conclude that there exists significant difference in the birth weights of a mother's first child and second child at 10% level of significance."

Move the terms

5x - 7x = -5 + 35

About 1407 sharks would be needed to have a margin of error of 0.25

Margin of error is used to determine by what value there is deviation from the real value. Margin of error (E) is given by:

[tex]E=Z_\frac{\alpha}{2} *\frac{standard\ deviation}{\sqrt{sample\ size} }[/tex]

The 90% confidence level have a z score of 1.645. Hence for E = 0.25, standard deviation = 5.7 feet, hence:

[tex]0.25=1.645*\frac{5.7}{\sqrt{sample\ size}}\\ \\sample\ size=1407[/tex]

Remark

You have to assume that O is the center of the circle. Two sectors are marked as equal, so equate them to find x

Equation and Solution

5x + 5 = 4x - 20               Subtract 5 from both sides

5x + 5 - 5 = 4x+ 20 - 5    Combine

5x = 4x + 15                     Subtract 4x from both sides.

5x-4x = 4x-4x + 15

x = 15

TOU = 5*15 + 5 = 80

VOW = 80                         TOU and VOW  are marked as equal

UOV = 6x -20 =  70

Total of all three = 80 + 80 + 70 = 230

I got x+y is (less than or equal to) 55 for the first inequality and 60x+40y>600 for the second one!

Since Blaine can sell a maximum of 55 tickets, the first inequalitly is x+y is less than OR EQUAL TO 55. Since the tickets in the back section cost $40 each, 40y represents the money made from those tickets. Blaine needs to make 600 in sale so the inequality is 60x+40y>600.
