Answer:

Table A

Step-by-step explanation:

If you do delta method (Change in y and x)

For example, 120-24

______ = 96/8

10-2

Then you divide both the numerator and denominator by the denominator (which is 8) and that gets us to 12 as our answer. Do the same method for all of the numbers in table A.

In a study of the accuracy of fast food drive-through orders, one restaurant had 34 orders that were not accurate among 371 ord

postnew [5]

Answer:

The claim that he rate of inaccurate orders is equal to 10% is supported by statistical evidnece at 5% level

Step-by-step explanation:

Given that in a study of the accuracy of fast food drive-through orders, one restaurant had 34 orders that were not accurate among 371 orders observed.

Sample proportion $p=0.092\\q=1-p = 0.908\\n = 371$

$H_0: p =0.10\\H_a: p \neq 0.10$

(Two tailed test at 5% significance level)

p difference = $0.092-0.100\\=-0.0084$

Std error if H0 is true = $\sqrt{\frac{0.1(0.9)}{371} } \\=0.016$

Test statistic Z = p diff/std error

=0.539

p value = 0.5899

Since p > 0.05 accept null hypothesis

The claim that he rate of inaccurate orders is equal to 10% is supported by statistical evidnece at 5% level

How many 3/4 cup servings are in 12 cups of cherries?

AveGali [126]

Answer:

16 serving.

Step-by-step explanation:

Given: 3/4 cup servings.

Now, computing the number of serving in 12 cups of cherries.

Using unitary method to solve.

∴ Number of serving= $total\ cups \times number\ of\ serving\ per\ cup$

Number of serving in one cup is $\frac{4}{3}$

Number of serving in 12 cups = $12\times \frac{4}{3} = 16 \ serving$

Number of serving in 12 cups= $16\ serving$

∴ There are 16 serving is possible in 12 cups of cherries.
