Answer:
-44° F
Step-by-step explanation:
In order to get the temperature after the decrease, we need to subtract 16 from -28. You can write this as -28 - 16, or (-28) + (-16) because subtracting a positive number from a negative number is just like adding two negative numbers.
Furthermore, adding negative numbers is just like adding positive numbers, but just with a negative sign. So, (-28) + (-16) = <u>-44</u>.
Answer:
You should stock 59 thousands of postcards
Step-by-step explanation:
In the standard normal distribution table, you want to find the Z with probability 0.4, which is (see figure attached) 1.28. Z is calculated as follows:
Z = (x - μ)/σ
where μ is the mean and σ is the standard deviation. Replacing with data:
1.28 = (x - 50)/7
x = 1.28*7 + 50 = 59 thousands of postcards
So, approximately 80% of the demand would be satisfied with a number of postcards between 41000 and 59000 (notice the curve is symmetrical).
