Answer:
A. 64%, B. 62%
Step-by-step explanation:
Find how many people do not have an email account.
168 + 24 = 192 Find the percentage.
192/300 = 0.64 Hence, 64% of shoppers don't have an email.
Do the same for B.
168 + 18 = 186
186/300 = 0.62
62% of shoppers don't have access to a computer.
Pythagorean theorem:
AB = √30^2 + 16^2 = 34
These are similar triangles.
∠BAC is congruent to ∠BAD
∠ACB is congruent with ∠ABD (both right angles)
Using ratios:
AC / AB = AB / (AC + CD)
AC + CD = AB² / AC
CD = AB² / AC - AC
CD = 34² / 16 - 16
CD = 56.25
The answer to this question is 56.
