I can not see the pic so can u explain the question
This problem calls for a simple substitution. We need to substitute 3x in for y in the equation 3x + 2y = 18 and then simplify by combining like terms.
3x + 2y = 18
y = 3x
3x + 2(3x) = 18
3x + 6x = 18
<u>9x = 18</u>
Now, if you want to solve for x, just divide both sides by 9 and simplify:
9x / 9 = 18 / 9
<u>x = 2</u>
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
