Since each batch takes
2 1/2 cups and he's making 3 1/2 batches,
You multiply the two numbers. First change them into improper fractions.
2 1/2 = 5/2
3 1/2 = 7/2
5/2 * 7/2 = 35/4
Simplify 8 3/4 cups flour

1 batch=2 1/2 cups of flour
3 1/2 batches= x cups of flour

1batch 3 1/2 batches
___________ = _____________
2 1/2 cups x cups

Cross multiply
1x=8 3/4
divide both sides by 1
x=8 3/4 cups

Answer= 8 3/4 cups of flour

A box with a square base and no top is to be built with a volume of 4000 in3. find the dimensions of the box that requires the l

vekshin1

Let the length of the square base be x inches .

And the height of the box be y inch .

Volume = x*x*y

4000 = x *x *y

$y = \frac{4000}{x^2}$

S = x*x + 2xy + 2 x y

$S = x^2 + 4 xy$

$S = x^2+ 4x* \frac{4000}{x^2}$

$S = x^2 + \frac{16000}{x}$

$S ' = 2x - \frac{16000}{x^2}$

S ' =0

$2x - \frac{16000}{x^2}=0$

$2x^3 - 16000 = 0$

$x^3 = 8000$

x = 20

$y = \frac{4000}{20^2} = \frac{4000}{400} = 10$

Suppose a sample of 972972 tenth graders is drawn. Of the students sampled, 700700 read above the eighth grade level. Using the

max2010maxim [7]

Answer:

The 85% confidence interval for the population proportion of tenth graders reading at or below the eighth grade level is (0.259, 0.301).

Step-by-step explanation:

In a sample with a number n of people surveyed with a probability of a success of $\pi$ , and a confidence level of $1-\alpha$ , we have the following confidence interval of proportions.

$\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}$

In which

z is the zscore that has a pvalue of $1 - \frac{\alpha}{2}$ .

For this problem, we have that:

972 students, 700 read above the eight grade level. We want the confidence interver for the proportion of those who read at or below the 8th grade level. 972 - 700 = 272, so $n = 972, \pi = \frac{272}{972} = 0.28$
