One question in a survey about what kind of cars people prefer to drive is:

“Would you prefer a ‘soccer Mom’ minivan or a ‘cool Mom’ convertible?”

This question contains:

A) data
B) statistics
C) bias
D) errors

The question is biased toward mothers, and does not consider women who do not have kids. A biased question leans toward a certain group, or set of groups, of people; at the same time, other groups are left out and not represented. One way to remove the bias is to ask "Would you prefer a minivan or a convertible?".

answear:

a

step-by-step explanation: a

d. bc = 12 and ef = 16

step-by-step explanation:

we are given that δabc : δdef such that .

also, it is given that

so, from the options, we need that .

a.

b.

c.  

d.

as, we can see that only option d gives the same ratio as i.e. .

hence, the possible lengths are bc = 12 and ef = 16.
