Answer:
b. E(X) = 3.015, STDEV(X)= 0.049, P (X ≤ 2.98) = 0.2941
Step-by-step explanation:
An uniform probability is a case of probability in which each outcome is equally as likely.
For this situation, we have a lower limit of the distribution that we call a and an upper limit that we call b.
The mean of the uniform probability distribution is:

The standard deviation of the uniform distribution is:

The probability that we find a value X lower than x is given by the following formula.

Uniform distribution between 2.93 and 3.1 volts
This means that
. So
Mean:

Standard deviation:

What is the probability that a battery has a voltage less than 2.98?

So the correct answer is:
b. E(X) = 3.015, STDEV(X)= 0.049, P (X ≤ 2.98) = 0.2941
Answer:
92.5
Step-by-step explanation:

cross multiply:
18.5 · 500 = 9250
100 · x = 100x
isolate x by dividing 100 from both sides:
x = 92.5
hope this helps!
00.7 is the value
(It’s not allowing me to post cuz it’s short)
Both of the first two choices represent the amount Connor paid.
15% = 0.15, so when you subtract 15% of d from d, you get the 2nd expression. When you simplify that, you get the 1st expression.
The correct choices are ...
• 0.85d
• d - 0.15d
Volume=π r(square)×height so pi×64(8square)×12=2412.74
