Zahara mixed 5 quarts of dry ingredients and 2 quarts of water to make a

krok68 [10]

Answer:

Zahara need to add 4 quarts of water to keep the consistency the same

Step-by-step explanation:

Let

x -----> the amount of dry ingredients in quarts

y -----> the mount of water in quarts

we know that

Batch 1

$\frac{x}{y}=\frac{5}{2}$

Isolate variable y

$y=\frac{2}{5}x$ ----> equation A

Batch 2

For x=10

substitute in the equation A and solve for y

$y=\frac{2}{5}(10)=4$

The ratio batch 2 is $\frac{10}{4}$

therefore

Zahara need to add 4 quarts of water to keep the consistency the same

Find the distance between the points (0, 10) and (–9, 1).

dimulka [17.4K]

$\\ \sf\longmapsto \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

$\\ \sf\longmapsto \sqrt{(-9-0)^2+(1-10)^2}$

$\\ \sf\longmapsto \sqrt{(-9)^2+(-9)^2}$

$\\ \sf\longmapsto \sqrt{81+81}$

$\\ \sf\longmapsto \sqrt{162}$

$\\ \sf\longmapsto 12.42$

The Ransin Sports Company has noted that the size of individual customer orders is normally distributed with a mean of $112 and

Mashutka [201]

Answer: 2.71

Step-by-step explanation:

We know that the formula to calculate the standard error is given by :-

$S.E.=\dfrac{\sigma}{\sqrt{n}}$ , where $\sigma$ is the standard deviation and 'n' is the sample size.

Given : Standard deviation : $\sigma=\$9$

Sample size : $n=11$

Then , the standard error of the mean is given by :-

$S.E.=\dfrac{9}{\sqrt{11}}=2.7136021012\approx2.71$

Hence, the standard error of the mean = 2.71

Answer: 13

Step-by-step explanation:

/ 5 + 12i/ = $\sqrt{(5 + 12i)(5 + 12i)}$

= $\sqrt{25 + 144}$

= $\sqrt{169}$

= 13
