96 degrees is your answer
supplementary means the angles add up to be 180 degrees. if 1 angle is 84 degrees then 180-84=96
Area of a circle is = PI x r^2
Area = 27 PI
This means the radius would be the square root of 27:
√27 = 3√3
The answer is F.
Answer:
Kayla plays on average 0.2 more chess games than Becker
Step-by-step explanation:
The first thing we must do is calculate the mean of each one.
Becker:
(5 + 2 + 4 + 1 + 1 + 4 + 5 + 3 + 2 + 1) / 10 = 2.8
Kayla:
(2 + 3 + 1 + 1 + 4 + 1 + 5 + 3 + 5 + 5) / 10 = 3
if we subtract these averages, we have to:
3 - 2.8 = 0.2
which means that Kayla plays on average 0.2 more chess games than Becker. Since it is not even a complete game, the difference between the two is very small and almost irrelevant.
Answer:
4.01% probability that the battery will break down during the warranty period
Step-by-step explanation:
When the distribution is normal, we use the z-score formula.
In a set with mean
and standard deviation
, the zscore of a measure X is given by:

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.
In this question, we have that:

a. What is the probability that the battery will break down during the warranty period
Warranty of 2 years = 24 months. So this is the pvalue of Z when X = 24.



has a pvalue of 0.0401
4.01% probability that the battery will break down during the warranty period
Answer:
True
Step-by-step explanation:
same numbers on both sides = equivalent expression
