The sampling distribution of x has a mean μₓ = <u> μ </u> and standard deviation σₓ =​ <u> σ/√n </u>.

In the question, we are given that a random sample of size n is drawn from a large population with mean μ and standard deviation σ.

We are asked to find the mean and the standard deviation for the sampling distribution of the variable x for this sample.

The sample mean is regularly distributed, with a mean μₓ = μ and standard deviation σₓ = σ/√n, where n is the sample size, for samples of any size taken from populations that have a normal distribution.

Thus, the sampling distribution of x has a mean μₓ= <u> μ </u> and standard deviation σₓ=​ <u> σ/√n </u>.

Anita's, a fast-food chain specializing in hot dogs and garlic fries, keeps track of the proportion of its customers who decide
timama [110]
<span>Anita's reports that 52% of its customers order their food to go. If this proportion is correct, what is the probability that, in a random sample of 5 customers at Anita's, exactly 3 order their food to go? 

Binomial Problem with n = 5 and p(to go) = 0.52


P(x=3) = 5C3(0.52)^3*(0.48)2 = binompdf(5,0.52,3) = 0.3240

Which statement is true about the product square root of 2 (5 + square root of 8 )? (2 points)
Oksana_A [137]

Answer:

d

Step-by-step explanation:

when the equation is written out, you get \sqrt{2} (5+\sqrt{8} ) the square root of 8 can be rewritten as 2 times the square root of 2. if you distribute the root two into the parenthesis you get 5 root two plus 4, because two root two times two comes out to two times two which is four. so your answer is d, 4 + 5 sqrt 2

Un depósito de riego tiene una capacidad de 24000 litros. Un día de un depósito de riego se consumen 2/3 de él, al día siguiente
malfutka [58]

Step-by-step explanation:

Un deposito de riego tiene una capacidad de 24000 litros. Un día se consumen 2/3 del deposito. al día siguiente no se riega y el deposito recupera 1/3 de su capacidad. Al día siguiente se consumen 6000 litros. Si inicialmente el deposito contenía 18000 litros. ¿Que fracción del total queda el ultimo día?

Comenzamos:

El deposito tiene: 18.000 litros

Se consumen 2/3 del depósito: 24.000 * 2/3 = 16.000 litros

Queda: 18.000 - 16.000 = 2.000 litros

Recupera 1/3 de su capacidad: 24.000 * 1/3 = 8.000 litros

Ahora tiene: 8.000 + 2.000 = 10.000 litros

Se consumen 6.000 litros: 10.000 - 6.000 = 4.000 litros

Fracción que representa sobre el total:

\frac{4.000litros}{24.000litros}=\frac{1}{6}

24.000litros

4.000litros

=

6
