If im correct it would be -2(2)+4(-2)-5 which is -4-8-5 which would be -17
Answer:
I think it's a or b but if I get you this wrong I'm sorry try with a first then b again I aploizge if I get you this wrong.
Answer:
The area of the shaded region is 0.9082.
Step-by-step explanation:
Problems of normally distributed samples can be 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, which is the area of the shaded region, 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:

Area of the shaded region:
pvalue of Z



has a pvalue of 0.9082
So
The area of the shaded region is 0.9082.
The greatest common factor of two numbers is, as the name suggests, the greatest integer that divides both numbers.
You number are already factored in product of primes, so it is obvious that the first number 133 = 19x7 is divisible by 1, 7, 19 and 133.
The same goes for 15 = 3x5: it is divisible by 1, 3, 5 and 15.
As you can see, there is no non-trivial divisor which is common to both number, so the answer is 1
