Mathematics
1 answer:
ss7ja [257]3 years ago

Answer:

The length of GH is 2 inches

Step-by-step explanation:

The given parameters are;

Parallelogram ABCD ~ Parallelogram EFGH

Segment BC of parallelogram ABCD corresponds to segment FG of parallelogram EFGH

Similarly

Segment CD of parallelogram ABCD corresponds to segment GH of parallelogram EFGH

In parallelogram ABCD, we have;

Segment BC = 21 in.

Segment CD = 6 in.

In parallelogram ABCD, we have;

Segment FG = 7 in.

Given that parallelogram ABCD is similar to parallelogram EFGH, we have;

\dfrac{\overline{BC}}{\overline{FG}} = \dfrac{\overline{CD}}{\overline{GH}}

Which by substitution, gives;

\dfrac{21}{7} = 3 = \dfrac{6}{\overline{GH}}

\therefore \overline{GH} = \dfrac{6}{3}  = 2

\overline{GH}= 2 inches

galina1969 [7]

Answer:

a. P=0.04

b. P=0.54

c. P=0.96

Step-by-step explanation:

If half of the college graduates are married, then we have:

- 21% are college graduates and married.

- 21% are college graduates and not married.

If 75% of the workers are married, and 21% of the workers are college graduates and married, then (75%-21%)=54% of the workers are not college graduates that are married.

If 25% of the workers are married, and 21% of the workers are college graduates and not married, then (25%-21%)=4% of the workers are not college graduates that are not married.

a) P=0.04 (explanation above)

b) P=0.54

c) In this case, the probability is the complement of point "a". Then we can calculate it by substracting the probability of not being married and not being a college graduate.

P=1-0.04=0.96
