Answer:
0.40517 is the probability
Step-by-step explanation:
The first thing to do here is to calculate the corresponding z-score
Mathematically;
z-score = x-mean/SD
from the question,
x = 78, mean = 75 and SD = 12.5
Plugging these values in the z-score equation, we have;
z-score = (78-75)/12.5 = 3/12.5 = 0.24
So the probability we want to calculate is that;
P(z < 0.24)
we can get this by using the standard normal distribution table,
The value according to the table is;
0.40517
1 - <span>A.The morning temperature was 5 degrees above the afternoon temperature.
2 - </span><span>B.The younger brother owes Bill $12.75, and the older brother does not owe him any money.
3 - question was not completed</span>
Step-by-step explanation:
Straight line = 180 °
5x + 78 = 180
5x = 180 - 78
5x = 102
x = 20.4
and y = 78 ° because y is an opposite angle of 78 °
You add each number that is in the same position correlated to the box. Ex: 12+-3=9
8,000 kilograms = 8000000 grams
