Answer:
Let us first jot down all the data given in the question;
Number of low quality computers (LQ) = 72
Number of medium quality computers (MQ) = 112
Number of high quality computers (HQ) = 711
∴ Total number of computers found in a random sample = 72 + 112 + 711 = 895.
∴ To find the probability of purchase for each category of computers, we use the following formula;
So,
P(LQ) = 72/895 = 0.08
P(MQ) = 112/895 = 0.125
P(HQ) = 711/895 = 0.794
Ans) Probability of purchase of a low quality computer, a medium quality computer, and a high quality computer are 0.08, 0.125, and 0.794 respectively

Answer:
The original point P is (-1, -5)
Since the original point was reflected over the y axis then you would reflect over the x axis to get the original point and when you reflect over the x axis the x coordinates stay the same and you change the y coordinates to the opposite of what it is

Answer:
The area of the octagon is <u>505.76 </u>
Step-by-step explanation:
In this question, we are tasked with calculating the area of an octagon given the values of the apothem and the perimeter
Mathematically, the area can be calculated using the formula below;
Area = 1/2 × apothem × perimeter
where according to the question, the apothem = 11.6 inches and the perimeter = 87.2 inches
Plugging these value into the equation given above, we have
Area = 1/2 × 11.6 × 87.2 = 505.76
