Only c and d are giving the total as -66.
c) (-34) + (-32) = -66
d) (-30) + (-36) = -66
since it is mentioned as consecutive integers, answer d can be rejected.
Therefore the answer is c.
c) (-34) and (-32)
Answer: Andy will pay $1.38 and Emily will pay $0.84 .
Step-by-step explanation: Divide the cost by inches. Ex 7.20/120 or 8.70/145 and so so , you will get 0.06. This means that each inch cost 0.06 . Next you will just multiply that by how many inches each person needs . 23•0.06=1.38 and 14•0.84=0.84
Answer:
Step-by-step explanation:
Line is passing through the point and has slope (m) = - 9
General equation of line in point slope form is given as:
Therefore
This is the required equation of line in point slope form.
Given Information:
Mean weekly salary = μ = $490
Standard deviation of weekly salary = σ = $45
Required Information:
P(X > $525) = ?
Answer:
P(X > $525) = 21.77%
Step-by-step explanation:
We want to find out the probability that a randomly selected teacher earns more than $525 a week.
The z-score corresponding to 0.78 from the z-table is 0.7823
Therefore, there is 21.77% probability that a randomly selected teacher earns more than $525 a week.
How to use z-table?
Step 1:
In the z-table, find the two-digit number on the left side corresponding to your z-score. (e.g 0.7, 2.2, 1.5 etc.)
Step 2:
Then look up at the top of z-table to find the remaining decimal point in the range of 0.00 to 0.09. (e.g. if you are looking for 0.78 then go for 0.08 column)
Step 3:
Finally, find the corresponding probability from the z-table at the intersection of step 1 and step 2.
