Answer:
its a square, so all sides similar
28. SV = RT/2 = 5.7/2 = 2.8
29. RT^2 = RQ^2 + QT^2
--> RT = √
(4^2 + 4^2)
RT = √32 =5.7
30. perimeter of RVS = 2.8 + 2.8 + 4 = 9.7
I believe it’s a trapezoid but i’m not too sure... sorry :((
Answer:
2.28% probability that a randomly selected Tesla model 3 can travel more than 310 miles
Step-by-step explanation:
Problems of normally distributed samples are solved using 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 problem, we have that:

What is the probability that a randomly selected Tesla model 3 can travel more than 310 miles?
This is 1 subtracted by the pvalue of Z when X = 310. So



has a pvalue of 0.0228
2.28% probability that a randomly selected Tesla model 3 can travel more than 310 miles
