-1.99, 1.99
Step-by-step explanation:
Use a table to find the z-scores.
For the first z-score:
P(x < z) = 0.0233
z = -1.99
For the second z-score:
P(x > z) = 0.0233
P(x < z) = 1 − 0.0233 = 0.9767
z = 1.99
Answer:
Step-by-step explanation:
The hardware store has 200 paintbrushes. They order 9 boxes with 12 paintbrushes each. This means that the total number of paintbrushes that was ordered is
12 × 9 = 108
Therefore, the total number of paintbrushes that the store has would be
200 + 108 = 308
They sell 11 boxes that have 6 paintbrushes each. This means that the total number of paintbrushes that they sold is
11 × 6 = 66
Therefore, the number of paintbrushes left would be
308 - 66 = 242
The manager's estimate is reasonable. They ordered about 120 paintbrushes and sold about 60 of them so they should have about 60 more paintbrushes than they started with.

Step-by-step explanation:
(1)
To find the unit rate divide the amount by 3
$3.84 ÷ 3 = $1.28 ← unit rate
(2)
Using proportion
$45 → 4 months
$180 → 4 × 
= 
= 16 months
(3)
sum the parts of the ratio, 8 + 1 = 9 parts
Divide 90 by 9 to find the value of one part
90 ÷ 9 = 10 ← value of 1 part
Thus
8 × 10 = 80
