h^2 - 12h + 20 can be factored to:

(h-10)(h-2)

These cannot be zero so, h cannot be 10 or 2.

Hello from MrBillDoesMath!

Answer:   h <> 10 and h <> 2      ( <> means not equal)

Discussion :


The domain restrictions are where the denominator  is 0. In this problem that occurs when

h^2 -12h + 20 = 0.

Factoring this equation gives

(h-10) (h-2) = 0

So   the values h = 10 and h =2 are NOT in the domain of this function,


Regards, MrB

8.33 Suppose Paul receives a 6% raise every year. After four such raises, what is the total percentage increase to the nearest w
Oksana_A [137]

Answer:

Given:

Suppose Paul receives a 6% raise every year.

To find:

After four such raises, the total percentage increase to the nearest whole percent.

The formula used to calculate percentage is: (value/total value)*100%.

Step-by-step explanation:

Step 1 of 1

Assume his salary is originally  100 dollars.

Then, in the next year, he would have 106 dollars, and in the next, he would have 112.36 dollars.

The next year he would have 119.1016 dollars and in the final year, he would have 126.247.

As the total increase is,

((126.247 -100)/100) *100

= 26.247%

the answer is 26%.

A certain disease occurs most frequently among older women. Of all age groups, women in their 60s have the highest rate of breas
Law Incorporation [45]

Answer:

The probability that a woman in her 60s has breast cancer given that she gets a positive mammogram is 0.0276.

Step-by-step explanation:

Let a set be events that have occurred be denoted as:

S = {A₁, A₂, A₃,..., Aₙ}

The Bayes' theorem states that the conditional probability of an event, say <em>A</em>ₙ given that another event, say <em>X</em> has already occurred is given by:

P(A_{n}|X)=\frac{P(X|A_{n})P(A_{n})}{\sum\limits^{n}_{i=1}{P(X|A_{i})P(A_{i})}}

The disease Breast cancer is being studied among women of age 60s.

Denote the events as follows:

<em>B</em> = a women in their 60s has breast cancer

+ = the mammograms detects the breast cancer

The information provided is:

P(B) = 0.0312\\P(+|B)=0.81\\P(+|B^{c})=0.92

Compute the value of P (B|+) using the Bayes' theorem as follows:

P(B|+)=\frac{P(+|B)P(B)}{P(+|B)P(B)+P(+|B^{c})P(B^{c})}

            =\frac{(0.81\times 0.0312)}{(0.81\times 0.0312)+(0.92\times (1-0.0312)}\\

            =\frac{0.025272}{0.025272+0.891296}

            =0.02757\\\approx0.0276

Thus, the probability that a woman in her 60s has breast cancer given that she gets a positive mammogram is 0.0276.
