Answer:
6.7 = 6
-0.92= -
-0.1= -
-5.05=-5
Step-by-step explanation:
:-)
First rewrite the decimal as a number with 1 in the denominator.
2nd multiply to remove 2 decimal places by (100/100)
3rd reduce the result of the multiplication
Then simplify the improper fraction

the arc length is calculated by the formula then
or it can be calculated using the circumference of the circle since we have a semicircle the circumference 2πr must be divided by 2 С=2πr:2=πr =8π=<u>25,12</u>
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
