Answer:
The number of games must a store sell in order to be eligible for a reward is 135.
Step-by-step explanation:
Let the random variable <em>X</em> represent the number of video games sold in a month by the sores.
The random variable <em>X</em> has a mean of, <em>μ</em> = 132 and a standard deviation of, <em>σ</em> = 9.
It is provided that the company is looking to reward stores that are selling in the top 7%.
That is,
.
The <em>z</em>-score related to this probability is, <em>z</em> = 1.48.
Compute the number of games must a store sell in order to be eligible for a reward as follows:



Thus, the number of games must a store sell in order to be eligible for a reward is 135.
Answer: $37.50
Step-by-step explanation: Assuming you mean 25% off and not 25% of the original price, first convert 25% to a decimal by dividing by 100. 25%/100=0.25. Multiply the price by 0.25. 50*0.25=12.5. Subtract the discount from the original price. 50-12.5=37.5.
Answer:
23
Step-by-step explanation:
x+x+1=x+2=72
3x+3=72
3x=69
x=23
23+24+25=72
You have to find the cos of angle A, so use the Pythagorean equation and trig laws to find the other side of the triangle created by angle A. 3^2 + x^2 = 5^2. x=4. This means cos(A) = 4/5). Make both cos (A) and cos (B) have equal denominators, and add. 148/185 + 60/185 = 208/185. This answer is correct, though it doesn’t appear to be any of the answers you wrote, so either those answers are wrong or you wrote something incorrectly in the problem.
