Answer:
x= 16 degrees
Step-by-step explanation:
the angles can be a little hard to remember but just know that the angles that are outside of the transversal are exterior angles and if they are on the opposite sides of the line that passes through the parallel lines then they're alternate exterior angles and those angles that are inside are interior angles and if they are on the opposite sides of the line passing through the parallel then they are alternate interior angles .
Using the normal distribution, it is found that the percentages are given as follows:
The z-score of a measure X of a normally distributed variable with mean and standard deviation
is given by:
The prorportion of students who receive an A is <u>one subtracted by the p-value of Z = 1.8</u>.
Looking at the z-table, Z = 1.8 has a p-value of 0.9641.
1 - 0.9641 = 0.0359.
3.59% of the grades will be A.
For B, it is the <u>p-value of Z = 1.8 subtracted by the p-value of Z = 1.1</u>, hence:
0.9641 - 0.8643 = 0.0998.
9.98% of the grades will be B.
For C, it is the <u>p-value of Z = 1.1 subtracted by the p-value of Z = -1.2</u>, hence:
0.8643 - 0.1151 = 0.7492.
74.92% of the grades will be C.
For D, it is the <u>p-value of Z = -1.2 subtracted by the p-value of Z = -1.9</u>, hence:
0.1151 - 0.0287 = 0.0864.
8.64% of the grades will be D.
For F, it is the <u>p-value of Z = -1.9</u>, hence 2.87% of the grades will be F.
