Answer:
A
Step-by-step explanation:
when multiplying two powers that have the same base, you can add the exponents.
8+3=11
to multiply two exponents with the same base, you keep the base and add the powers.
The probability that the instructor asks one of Sam and John whose probabilities of being asked are as indicated in the task content is; 0.12.
<h3>What is the probability that the instructor asks one of these two students?</h3>
It follows from the task content that the probability that Sam is being asked is; 0.05 while that for John being asked is; 0.07.
Consequently, we may conclude that the probability of either of the two classmates being asked the question in discuss is; the sum of the probabilities and hence, we have;
P(Sam or John) = 0.05 + 0.07
= 0.12.

Answer: 15cm and 5cm
Step-by-step explanation:
A rectangle's area is the product of the length and width
Given length x and width y, 2x+2y = 40 and x*y = 75.
Verifying my answer:
2(15)+2(5) = 40
30+10 = 40
40 = 40
15*5 = 75
75= 75
This is a week late so I hope this helped.
