<h3>Answer:</h3>

B. 1 : 26

Step-by-step explanation:

Let the volume of large cone, the volume of water and the volume of air in the cone be V,

Vw and Va.

Since the cone of water is similar to the large cone and we know its height is x3 smaller,

Vw = (1/3)^3 * V = V/27

Also, Va = V - Vw

= V - V/27 = 26/27 V

Hence, Vw : Va

1 : 26

You measure 20 dogs' weights, and find they have a mean weight of 64 ounces. Assume the population standard deviation is 11.5 ou

Assoli18 [71]

95% confidence interval would be (58.96, 69.04).

Step-by-step explanation:

Since we have given that

Number of dogs' weight = 20

Mean = 64 ounces

Standard deviation = 11.5 ounces

We need to find the 95% confidence interval.

So, z = 1.96

so, interval would be

$\bar{x}\pm z\dfrac{\sigma}{\sqrt{n}}\\\\=64\pm 1.96\times \dfrac{11.5}{\sqrt{20}}\\\\=64\pm 5.04\\\\=(64-5.04,64+5.04)\\\\=(58.96,69.04)$

Hence, 95% confidence interval would be (58.96, 69.04).

Pls help due tomorrow just numbers 7 - 12

Luden [163]

Answer:

Step-by-step explanation:

7). 5.75% = $\frac{5.75}{100}$ = $\frac{575}{10000}$ = $\frac{23}{400}$

10). $16\frac{2}{3}$ % = $\frac{50}{3}$ % = $\frac{50}{300}$ = $\frac{1}{6}$

12). $79\frac{5}{6}$ % = $\frac{479}{6}$ % = $\frac{479}{600}$

Now is you turn. You can do it!
