The normal distribution is also known as the Gaussian distribution. The percentage of all possible values of the variable that are less than 4 is 15.87%.
<h3>What is a normal distribution?</h3>
The normal distribution, also known as the Gaussian distribution, is a symmetric probability distribution about the mean, indicating that data near the mean occur more frequently than data distant from the mean. The normal distribution will show as a bell curve on a graph.
A.) The percentage of all possible values of the variable that lie between 5 and 9.
P(5<X<9) = P(X<9) - P(5<X)
= P(z<1.5) - P(-0.5<z)
= 0.9332 - 0.3085
= 0.6247
= 62.47%
B.) The percentage of all possible values of the variable that exceed 1.
P(X>1) = 1 - P(X<-2.5)
= 1-0.0062
= 0.9938
= 99.38%
C.) The percentage of all possible values of the variable that are less than 4.
P(X<4) = P(X <4)
= P(z<-1)
= 0.1587
= 15.87%

B) m∠C = m∠F
Because now m∠B = m∠E because of the 180 total rule, and if all 3 ∠s are = then they are similar
Answer:
74.47%
Step-by-step explanation:
Divide the total number of students by the number who passed
passed/total
35/47
0.74468085
As a percent:
0.74468085*100=74.4680851
Rounded to the nearest hundreth:
74.4680851
74.47%
So, 74.47% passed the geometry test
Hope this helps! :)
Answer: You put this in math when this is french, if you want this in english, the translation is ”what was the temperature at noon that day”
Step-by-step explanation:
1a. You can't do much for it, answer could be x(x+8)
1b. (x+5)(x+3)
1c. (x + 3y)(x - 3y)
1d. (5x - 4) (x + 2)
2. It's very likely you need a protractor and a ruler for this. If not, tell me and I'll try to find it.
