Question help the construction of the tminus−statistic for a oneminus− and a twominus−sided hypothesis

1 answer:

5 0

The construction for the two sided and one sided hypothesis is the same so the answer is letter d. the explanation behind this is: If you use a two-tailed test it just means that you need to allot half of your alpha to testing statistical significance. If your alpha is equal to 0.05, then this means that 0.025 must be in each tail of the distribution while for the one-tailed test, you will only allot your alpha in one-side.

A 6 inch personal pizza has 640 calories, with 240 of those from fat. A 12 inch pizza is cutinto 8 slices. Estimate the number o

MissTica

Given:

Number calories in a 6-inch pizza = 640 calories

For the pizza of 6 inch

$A=\pi(3)^2=9\pi$

For the pizza of 12 inch

$A=\pi(6)^2=36\pi$

Number calories in a 6-inch pizza = 640 calories, therefore:

$\frac{A_{6\text{ inch}}}{A_{12\text{ inch}}}=\frac{640}{x}$

Substitute:

$\begin{gathered} \frac{9\pi}{36\pi}=\frac{640}{x} \\ Simplify \\ \frac{1}{4}=\frac{640}{x} \end{gathered}$

And solve for x:

$\begin{gathered} 1\cdot x=4\cdot640 \\ x=2560 \end{gathered}$

Now, Estimate the number of calories in one slice of a 12 inch pizza:

$\frac{2560}{8}=320$

Answer: 320 calories

Okay well first let's find out the answer for the equation as given here;

4p^2 = 12p - 5

4p^2 - 12p + 5 = 0

4p^2 - 2p - 10p + 5 = 0

2p(2p - 1) - 5(2p - 1) = 0

(2p - 5)(2p - 1) = 0

p = 5/2, 1/2

now the question is asking what type of numbers are the solutions.

your answer is D) 2 rational solutions.

hope this helped (:
