A set of biology exam scores are normally distributed with a mean of 70 points and a standard deviation of six points X equal the score on a randomly selected exam from the set find P(X< 73)

Answers

Answer: .69

Step-by-step explanation:

Answer on khan

We can write the value in the range P(64 < {x} < 76) as 0.68.

What is standard deviation?

In statistics, the standard deviation is a measure of the amount of variation or dispersion of a set of values.

Given is that a set of biology exam scores are normally distributed with a mean of 70 points and a standard deviation of six points X equal the score on a randomly selected exam from the set.

It is given that -

μ = 70

σ = 6

For the range of {x}, we can write -

(μ - σ) < {x} < (μ + σ)

64 < {x} < 76

We can write the range of {z} value as -

(64 - 70)/6 < {z} < (64 + 70)/6

- 1 < {z} < + 1

Now -

P(64 < {x} < 76) = P(x < 76) - P(x < 64) = 0.84 - 0.15 = 0.68

Therefore, we can write the value in the range P(64 < {x} < 76) as 0.68.

0. The weight of an object on the Moon is about 16.5% of its weight on Earth. The weight of an astronaut on the Moon is 24.75 pounds. How much does the astronaut weigh on Earth?

Answers

Answer: 150 pounds

Step-by-step explanation:

Let the the astronaut weight on Earth be represented by x.

Based on the information given in the question, thus can be formed into an equation as:

16.5% of x = 24.75

16.5% × x = 24.75

16.5/100 × x = 24.75

0.165x = 24.75

x = 24.75/0.165

x = 150 pounds

The astronaut weigh 150 pounds on Earth.
