Answer:

0.576

Step-by-step explanation:

First, you would change the percent to a decimal which is 0.0008

Second, you would multiply that by 720 (0.0008 x 720)

Third you would find your answer by calculating it, which is 0.576.

Another way

0.0008/ 100 × <em>a/720 ≡ 0.576</em>

Answer:

Two-sample t test.

Because we have two different sections and we want to see if exists difference between the two averages. Both sections are independent so it can be considered as different samples.

Step-by-step explanation:

Two-sample t test.

Because we have two different sections and we want to see if exists difference between the two averages. Both sections are independent so it can be considered as different samples.

If we don't know the population deviations, so for this case is better apply a two sample t test to compare means, and the statistic is given by:

$t=\frac{(\bar X_{A}-\bar X_{B})-12}{\sqrt{\frac{s^2_{A}}{n_{A}}+\frac{s^2_{B}}{n_{B}}}}$ (1)

t-test: "Is used to compare group means. Is one of the most common tests and is used to determine whether the means of two groups are equal to each other".

Answer:

$g^2+3g-825$

Step-by-step explanation:

$(g^2 – 494 + 59 + 9) + (-393 + 3g– 6) = (g^2 – 426) + (-399 + 3g) = g^2 – 825 + 3g = g^2+3g-825$

Sati [7]

Parallel = same slope
3y = 2x -4
y = 2/3x - 4/3, slope = 2/3
y - y1 = m(x - x1)
Plug in the point and slope
y - 3 = 2/3(x - 1)
The answer is D

Kevin uses 2 and 1/4 cups of ravens for every half cup of peanuts when making a snack mix how many cups of raisins does Kevin us

Dmitrij [34]

Answer:

For 1 cup of peanut Kevin will use $\frac{9}{2} \ cups \ \ \ OR \ \ \ 4\frac{1}{2} \ cups$ of raisins.

Step-by-step explanation:

Given:

$\frac{1}{2}$ cups of peanuts = $2\frac{1}{4}$ cups of raisin

$2\frac{1}{4}$ can be rewritten as $\frac{9}{4}$

$\frac{1}{2}$ cups of peanuts = $\frac{9}{4}$ cups of raisin

We need to find number of cups of raisins used in 1 cup of peanut.

Solution:

Now we know that;

$\frac{1}{2}$ cups of peanuts = $\frac{9}{4}$ cups of raisin

So 1 cup of peanut = number of cups of raisins used in 1 cup of peanut

Now by using Unitary method we get;

number of cups of raisins used in 1 cup of peanut = $\frac{\frac{9}{4}}{\frac{1}{2}}=\frac{9}{4}\times \frac{2}{1} = \frac{9}{2} \ cup \ \ \ OR \ \ \ 4\frac{1}{2} \ cup$

Hence For 1 cup of peanut Kevin will use $\frac{9}{2} \ cups \ \ \ OR \ \ \ 4\frac{1}{2} \ cups$ of raisins.
