Answer:
x = -3
Step-by-step explanation:
Notice that the addition of angle <CDH plus angle <HDE have to give the measure of angle <CDE (which is 144 degrees as stated in the problem)
Then, we can say in equation form:
<CDH + <HDE = 144
replacing with their expressions in terms of x:
x + 93 + 57 + x = 144
solving for x:
2 x + 150 = 144
2 x = 144 - 150
2 x = - 6
x = -3
Answer:
About 84 % of the area is between z equals minus 2 and z equals 2
Step-by-step explanation:
A standard normal distribution refers to a normal distribution with a mean of 0 and a standard deviation of 1.
To find the percentage of area that is between -2<z<2, we are going to use a graphic calculator. We get that P(-2<z<2) = 0.84
Therefore, About 84 % of the area is between z equals minus 2 and z equals 2
