Stella [2.4K]

Answer:

The ferris wheel has a maximum capacity of 64, the domain is [0,64]

Step-by-step explanation:

Given in the question that,

the maximum number of people that can seat on the ferris wheel = 64

the minimum number of people that can seat on the ferris wheel = 0

Function to calculate the amount of money

M(p)=2p

Value of p can be any integer from zero to 64 so the domain of this function is

0 ≤ x ≤ 64

According to Eurostat, 55.2% of households in Italy have one child, the highest percentage in the Euro zone. A random sample of

Sladkaya [172]

Answer:

0.04

Step-by-step explanation:

In this case we must use the following formula to be able to find the standard error, which would be the square root, of the probability for its complement divided by the population:

SE= $\sqrt{\frac{p *(1-p)}{n} } \\$

Now, knowing that p = 0.552 and n = 160 we replace and we are left with:

SE = $\sqrt{\frac{0.552 *(1-0.552)}{160} } \\$

SE = $\sqrt{0.00154}$

SE = 0.039

Which means that the standard error of the proportion is 0.04

Help please.<br><br> Find x.

Degger [83]

You have to use the Geometric Mean for triangles to find x. Our form will look like this: $\frac{2}{x} = \frac{x}{6+2}$ which simplifies to $\frac{2}{x} = \frac{x}{8}$ . Cross multiply to get $x^{2} =16$ . Therfore, x = 4. Usually when we take the square root of a number we will end up with both the principle (positive) root and the negative one as well. But since the 2 things in math that will never EVER be negative are time and distance/length, we will not consider the -4. x = 4
