-4/9 times -5/8 you can cross cancel the 4 and 8 so it makes the problem -1/9 times -5/2 which equals -5/18
Solution :
Given data :
The mean length of the steel rod = 29 centimeter (cm)
The standard deviation of a normally distributed lengths of rods = 0.07 centimeter (cm)
a). We are required to find the proportion of rod that have a length of less than 28.9 centimeter (cm).
Therefore, P(x < 28.9) = P(z < (28.9-29) / 0.07)
= P(z < -1.42)
= 0.0778
b). Any rods which is shorter than
cm or longer than
cm that re discarded.
Therefore,
P (x < 24.84 or 25.16 < x) = P( -59.42 < z or -54.85)
= 1.052
Answer:
8
Step-by-step explanation:
4 different shirts would be 4 combinations. You can have one of each of the jeans on the mannequin, giving 4x2=8.
How do i find the graph to help you
The doctor has 35,602 and she needs 69,600.
We need to do subtraction to find out how much more she needs to raise.
69,600 - 35,602 = ?
69,600 - 35,602 = 33,998
The doctor needs to raise $33,998 more.
Your final answer is A. $33,998
