Answer:

Angle K

Step-by-step explanation:

Angle Z has the angle marking with one blue curve.

The one blue curve is also found on angle K in triangle NWK.

Therefore, the two angles are congruent, meaning they are the same measure.

antoniya [11.8K]

Answer:

A. 2.5 standard deviations below the average salary.

Step-by-step explanation:

In a normally distributed sample, the z-score measure how many standard deviations a measure is above or below the mean.

If the zscore is positive, the measure is above the mean.

If it is negative, the measure is below the mean.

A quality control specialist calculated thez-score associated with his own salary and found it was minus2.50. What is his salary?

This means that his salary is 2.5 standard deviations below the mean, that is the average salary.

The correct answer is A.

At a local sandwich shop the average customer spends $25 at dinner with a standard deviation of $2.30. In a simple random sample

oee [108]

Answer:

The probability that the mean receipt for dinner is between $24.50 and $25.50 is

P(24.50≤ x ≤ 25.50)= 0.8324

Step-by-step explanation:

Step(i):-

Given mean of Population(μ) = $25

Given standard deviation of the Population (σ) = 2.30

Sample size 'n' = 40

Let 'X' be the random variable in normal distribution

Given X₁ = 24.50

$Z_{1} =\frac{x-mean}{\frac{S.D}{\sqrt{n} } } = \frac{24.50-25}{\frac{2.30}{\sqrt{40} } } = -1.375$

Given X₂ = 25.50

$Z_{2} =\frac{x-mean}{\frac{S.D}{\sqrt{n} } } = \frac{25.50-25}{\frac{2.30}{\sqrt{40} } } = 1.3751$

Step(ii):-

The probability that the mean receipt for dinner is between $24.50 and $25.50

P(x₁≤ x ≤ x₂) = P(Z₁≤ z ≤ Z₂) = A(Z₂) + A(z₁)

P(24.50≤ x ≤ 25.50) = P(-1.375≤ z ≤ 1.375) = A(1.375) + A(1.375)

P(24.50≤ x ≤ 25.50)= 2 A( 1.375)

= 2 × 0.4162 ( from normal table)

= 0.8324

Final answer:-

The probability that the mean receipt for dinner is between $24.50 and $25.50 is 0.8324
