Thank you for posting your question here at brainly. The probe's elevation relative to sea level after the first minute, the probe dropped 11 feet per minute, therefore, it dropped 11 feet in the first minute. I hope the answer helps you.
The answer to the question
Answer:
a. p = n + m
where: n is the number of pens, and m is the number of pencils
b. p = 71
Step-by-step explanation:
Let the number of pens and pencils that Alex has be represented by n and m respectively.
But,
number of pens, n = 14
number of pencils, m = 57
Then,
total number of pens and pencils, p = number of pens + number of pencils
i.e p = n + m
p = 14 + 57
p = 71
The total number of pens and pencils that Alex has is 71.
Assuming uniform distribution and independence, then
<span>P(1st number less than 8 and 2nd number less than 8) = </span>
<span>P(1st number less than 8)*P(2nd number less than 8) = </span>
<span>(7/12)*(7/12) = about 34%</span>
