Answer: 0.002718
Step-by-step explanation:
Given : The population mean annual salary for environmental compliance specialists is about $62,000.
i.e. 
Sample size : n= 32
Let x be the random variable that represents the annual salary for environmental compliance specialists.
Using formula 
, the z-value corresponds to x= 59000 will be :
Now, by using the standard normal z-table , the probability that the mean salary of the sample is less than $59,000 :-
Hence, the probability that the mean salary of the sample is less than $59,000= 0.002718
Alright, if the original scale was 1 inch = 8 miles, and Dale's house to his school are 1 1/2 inches apart, let's find the amount of miles.
Here's a fast way. 1 inch is 8 miles, and half of 8 equals 4 miles, which is 1/2 of an inch., 8 + 4 = 12 miles.
So if his house and the school were 12 miles apart, and we we're using the 1 inch. = 6 miles scale, then it'd be 2 inches on the map.
How?
If 1 inch. = 6 miles
x inches = 12 miles
12/6 = 2
2 inches = x
Answer:
Step-by-step explanation:
The distance from Q to S is 2 - (-14), or 16.
We start at point Q. Note how 3 and 5 add up to 8, which allows us to write:
R = Q + (3/8)(16), or R = -14 + 6, or R = -8.
From R to S it is (5/8)(16), or 10 units.
The directed line segment is partitioned into segments of lengths 6 and 10, whose combined length is 16, as expected.
Answer:
Ed used 39/60 of one hour to complete his tasks.
Step-by-step explanation:
Find the least common denominator (LCD), which would be 20
Then, find how to get from 5 to 20 and 4 to 20.
Use division.
20/5 = 4, 20/4 = 5
After this, multiply the numerator to the according number.
2*4 = 8 = 8/20
1*5 = 5 = 5/20
Make the denominator 60 to represent 60 minutes in one hour
5/20*3/3 = 15/60
8/20*3/3 = 24/60
Add the two results.
15/60 + 24/60 = 39/60
