kherson [118]

Answer:

The answer is "0.765 and 0.2353".

Step-by-step explanation:

Please find the complete question in the attached file.

In point a:

P(a substantive term only)=0.75-0.2 =0.55

P(major health insurance only) = 0.45-0.20=0.25

P(both)= 0.20

P(renewal) =P(insurance and renewal term only)+P (substantial and renewable health insurance only)+P (both and renew)

=0.55\times 0.7+0.25 \times 0.8+0.2 \times 0.9 \\\\ =0.765

In point b:

In reality, the probability of having both life and major medical insurance provided the policyholder would renew next year

= \frac{\text{P(both and renew)}}{\text{P(renew)}}

=\frac{0.2\times 0.9}{0.765}\\\\=0.2353

Ming wrote the table of points below.
anzhelika [568]

Answer:

Ming has described a proportional relationship because the ordered pairs are linear and the line passes through the origin

Step-by-step explanation:

Given

x - y

5 - 10

10 - 20

15 - 30

Required

Determine if the data are proportional

The dataset is small; so, we can derive the relationship by observation.

By observing the x and y values, the relationship is:

y = 2x --- i.e. multiply x values by 2.

This is further proven by:

y = 2 * 5 = 10

y = 2 * 10 = 20

y = 2 * 15 = 30

y = 2 * 0 = 0 --- the origin

Hence, the dataset is proportional and it passes through the origin.
