Answer:
B = 5 and F = 5
Step-by-step explanation:
Step 1: B = 5 because 350(5) = 1750
Step 2: F = 5 because 525(5) = 2625
Step 3: 2625 + 1750 = 4375
The equation representing the cost of 6 chairs and a table is:
6x + x + 50 = 750
⇒
7x = 700
This equation is true for x = 100 because:
7(100) = 700
So, the cost of one chair will be $100.
Cost of table is $50 more than a chair, so the cost of one table is $150.
So the answers are:
$ 100
$ 100
$ 150
Z scores are (age - mean) / std dev
= 23 - 27 / 2 = -2 and 27-27 / 2 = 0
