A. p = 8n - 30
Each item n is $8.
Expenses totaling $30 are subtracted.
So if the profit (p) is $170.00,
170 = 8n - 30
Now you need to solve.
Add 30 to both sides.
200 = 8n
Divide both sides by 8.
25 = n
25 items were bought.
b. If 25 items were bought, but the expenses were instead $40, what would be the total profit?
p = 8(25) - 40
p = 200 - 40
p = 160
The profit decreased by 10.
Answer:
that is the nearest thousands decimal place
Answer:
-29
Step-by-step explanation:
On a number line, negative numbers lie on the left side of zero and positives on the right. The furthest to the right of the number line will be the large number and the furthest to the left will be the smaller. -10 is furthest to the right making it the larger integer and -29 the smallest.

Answer: 0.2134
Step-by-step explanation:
Given : Mean readings on thermometers =
Standard deviation =
We assume that the readings on thermometers are normally distributed.
Let x be the random variable that represents the reading on a random thermometer.
To find z-score :
For x = -0.99
For x= -0.32
By using the standard normal distribution table , the probability that a randomly selected thermometer reads between -0.99 and -0.32 will be :-
