Amanda earned a score of 940 on a national achievement test that was normally distributed. The mean test score was 850 with a st
snow_lady [41]
<span>In math notation, we've done this: z = (X - μ) / σ = (940 - 850) / 100 = 0.90 where z is the z-score X is Vivian's score (940) µ is the mean (850) σ is the standard deviation (100) As you may know, in a normal distribution it's expected that about 68% of all observations will fall within 1 standard deviation of the mean, 95% will fall within 2 standard deviations, and 99% will fall within 3 standard deviations. 
940 lie before the first standard deviation, in which 16.5% is above it
since 940 is 0.9 from the mean and 0.1 from the first standard deviation
so above it is 17.5 % = 0.175 or about 0.18 </span>

What is the sum of the 12th square number and the 9th square number
Inessa [10]

Answer: 225

Step-by-step explanation:

<u>What is a square number</u>?

A square number is a product of a number times itself

So, the 12th square number would be 12 * 12, or 12²

The 9th square number would be 9 * 9, or 9²

The equation would be 12² + 9²

So:

12² + 9²

= 144 + 81

= 225

So, the answer is 225

Use the information in the table. You are making a circle graph showing the total number of successful United States space launc
timama [110]

Answer:

52.9°

Step-by-step explanation:

step 1

we know that

The total number of successful United States space launches that happened in the years 1957-1995 is equal to

15+470+258+153+146=1,042

step 2

The numbers of successful United States space launches that happened in the years 1980-1989 is equal to

153

step 3

The percentage of successful United States space launches that happened in the years 1980-1989 is equal to

\frac{153}{1,042}(100)=14.68\%

step 4

Find out the measure of the central angle you would draw in a circle graph to represent the number of successful United States space launches  that happened in the years 1980-1989

we know that

In a circle, 360 degrees represent the 100%

so

using proportion

Find out the measure of the central angle by a percentage of 14.68%

\frac{360^o}{100\%}=\frac{x}{14.68\%}\\\\x=360^o(14.68\%)/100\%\\\\x= 52.9^o
