2 answers:

8 0

Think of quarters. 1 Quarter is equal to $0.25 and 4 quarters equal to 1.00. If you take a quarter away from your dollar you get 0.75. I would say the answer is 75.

25% is .25 as a decimal 100*.25=25 so 25% of 100 is equal to 25 because, 25% goes into 100% 4 times so we immediately know that where looking for a number that can go into 100 4 times and it just so happens that 25=25 is true and 100=100 is true so are answer is literally in the question.

An English professor assigns letter grades on a test according to the following scheme. A: Top 5% of scores B: Scores below the

tangare [24]

Answer:

Grade D score:

$69 \leq x \leq 74$

Step-by-step explanation:

We are given the following information in the question:

Mean, μ = 78.8

Standard Deviation, σ = 7.1

We are given that the distribution of scores on test is a bell shaped distribution that is a normal distribution.

Formula:

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

D: Scores below the top 77% and above the bottom 9%

We have to find the value of x such that the probability is 0.77

$P( X > x) = P( z > \displaystyle\frac{x - 78.8}{7.1})=0.77$

$= 1 -P( z \leq \displaystyle\frac{x - 78.8}{7.1})=0.77$

$=P( z \leq \displaystyle\frac{x - 78.8}{7.1})=0.23$

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

$\displaystyle\frac{x - 78.8}{7.1} =-0.739\\\\x = 73.55$

We have to find the value of x such that the probability is 0.09

$P(X < 0.09) = \\\\P( X < x) = P( z < \displaystyle\frac{x - 78.8}{7.1})=0.09$

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

$\displaystyle\frac{x - 78.8}{7.1} = -1.341\\\\x = 69.27$

Thus, the numerical value of score to achieve grade D is

$69 \leq x \leq 74$

Hello!

A straight line measures to 180°

The angle that measures 134 and x make a straight line

180 = 134 + x

Subtract 134 from both sides

46 = x

The answer is 46°

Hope this helps!
