The grades of a statistics midterm are normally distributed with a mean of 70 and a standard deviation of 2. Without using a calculator, what is the probability that a student will receive a grade between 74 and 76? Group of answer choices

a. 34.12%

b. 4.30%

c. 13.6%

d. 2.15%

The Empirical Rule can be used to solve this problem since a grade of 74 is exactly 2 standard deviations above the mean and a grade of 76 is exactly 3 standard deviations above the mean.

Step-by-step explanation:

This is all I know. But 34.12% is NOT the answer.

location: point 0

step-by-step explanation:

well, -8 to 10 on a number line is 18 spaces.

1/9 of 18 is 2.

so, 4/9 of 18 must be 8.

8 spaces from -8 (a) is 0.

so, 4/9 of the way from -8 to 10 is 0!

x = 17

step-by-step explanation:

in the given figure, two triangles are inscribed in a circle where ∠bae ≅ ∠dae which makes the side be and de equal so we can write it as:

3x - 24 = x + 10

solving this equation for x to get:

3x - x = 10 + 24

2x = 34

x = 34/2

x = 17

therefore, the value of x = 17.
