3. Luis wants to calculate the volume of his globe. The globe is in the shape of a sphere, as represented in

Aloiza [94]

The measure which is closest to the volume of Luis's globe is; 6301.2in³

<h3>Volume of a sphere</h3>

If the circumference of the globe along the equator is 72inches along the equator;

C = 72 = 2π× r

Hence, the radius of the globe can be evaluated as;

r = 72/(2×3.14)

r = 72/6.28

r = 11.46in.

On this note, the Volume, V of the globe is;

V = (4/3) × π × r³

V = (4/3) × 3.14 × 11.46³

V = 6301.2in³

The scores for a certain test of intelligence are normally distributed with mean 85 and standard deviation 11. Find the 90th per

jonny [76]

Answer:

99.1 is the 90th percentile of these scores.

Step-by-step explanation:

We are given the following information in the question:

Mean, μ = 85

Standard Deviation, σ = 11

We are given that the distribution of score is a bell shaped distribution that is a normal distribution.

Formula:

$z_{score} = \displaystyle\frac{x-\mu}{\sigma}$

We have to find the value of x such that the probability is 0.90

$P( X < x) = P( z < \displaystyle\frac{x - 85}{11})=0.90$

Calculation the value from standard normal z table, we have,

$P(z \leq 1.282) = 0.90$

Putting values, we get,

$\displaystyle\frac{x - 85}{11} = 1.282\\\\x = 99.1$

Thus, 99.1 is the 90th percentile of these scores.
