Answer:
b. the area to the right of 2
Step-by-step explanation:
Problems of normally distributed samples are solved using the z-score formula.
In a set with mean 
and standard deviation 
, the zscore of a measure X is given by:
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X, which is also the area to the left of Z. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X, which is the area to the right of Z.
In this problem:
Percentage who did better:
P(Z > 2), which is the area to the right of 2.
Given that,
Alonzo is $120 in debt. He makes $15 per hour. He wants to have at least $75 left over after he has paid off his debt.
To find,
The inequality and the solution.
Solution,
Let he make $x per hour. Here, $120 is fixed. $15 is added per hour.
ATQ,
For atleast, we use 
.
Subtract 120 from both sides.
So, the required answer is greater than -3.
I guess the answer is 31 because two sides are the same so 12is the sa,e on the other side and 12+12=24 plus the 7 equals 31cm.
Answer: The slope is -3/2
Step-by-step explanation:
To find the slope, find the difference in the y coordinates and divide it by the difference in the x coordinates.
y coordinates; 9 - 15 = -6
x coordinates : 8 - 4 = 4
Slope: -6/4 = -3/2
Answer: 305 miles
Step-by-step explanation: (60 times 1) + (55 times 3) + (40 times 2) = 305 miles
