Answer:

standard error of the mean (S.E) = 0.06

Step-by-step explanation:

<u><em>Explanation:</em></u>-

Given sample size 'n' = 500

Given variance of the Population = 900

The standard deviation of the Population = √900 = 30

The standard error of the mean is determined by

S.E = \frac{S.D}{\sqrt{n} } = \frac{30}{500} = 0.06

In the diagram below, RSTU is a rectangle, and the two shaded regions are squares.
sdas [7]

Answer:

length PQ = 8.9 m  

Step-by-step explanation:

The picture below completes the question you  asked. From the picture above RSTU is a rectangle . The two shaded square has a length of sides 8 m and 4 m respectively. The legs of the triangle is the sides of the 2 squares. Therefore, the triangle is a right angle triangle. The adjacent side is 4 m while the opposite side is 8 m.

Using Pythagoras theorem the hypotenuse of the triangle can be calculated below.

Pythagoras theorem

c² = a² + b² Therefore,

c² = 4² + 8²

c² = 16 + 64

c² = 80

square root both sides

c = √80

c = 8.94427191

c ≈ 8.9 m

length PQ = 8.9 m

For a standard normal distribution find the approximate value of p(z&lt;0.42)
Kruka [31]

Answer:

p(z<0.42) = 0.6628

Step-by-step explanation:

A normal distribution with a mean of 0 and a standard deviation of 1 is called a standard normal distribution. That is to say:

μ = 0

σ² = 1

Using a calculator, we find that:

p(z<0.42) = 0.6628 (See picture attached)
