BRCA1 is a gene that has been linked to breast cancer. Researches at Stanford University wanted to estimate what proportion of w

omen with a family history of breast cancer show a BRCA1 mutation. In 2014, they used DNA analysis to search for BRCA mutations in 173 women with family histories of breast cancer. Of the 173, they found that 29 had BRCA1 mutations. Calculate the Point Estimate. Give your answer to 3 decimal places.

Answer:

The point estimate for the proportion of women with BRCA1 mutation is 0.168

Step-by-step explanation:

The point estimate for the proportion of women with BRCA1 mutation is the number of women with this mutation divided by the size of the sample.

Of the 173, they found that 29 had BRCA1 mutations.

29/173 = 0.168

The point estimate for the proportion of women with BRCA1 mutation is 0.168

Answer:

C or 8

Step-by-step explanation:

Once again, first you ant to simplify the equation before putting in the numbers.  So the simplified equation is mh + mp -p/h +m. Then you put the numbers in. mh is actually 3(-1), which is -3. mp is really 3*4, which is 12. p/h is 4/-1, which is -4, and then you add m. So when you put the numbers is it ends up as -3 + 12 - 4 +3, which simplified is 8, or C

The difference between the most hours of sleep and the least of these students was 2.5 hours. True or false?​
SashulF [63]

The correct anwer is False

Explanation

According to the graph, it can be seen that a student has four hours of sleep as the minimum number of hours of sleep; two students have six hours of sleep, four students have six and a half hours of sleep, four have seven hours of sleep, three have seven and a half hours of sleep, five have eight hours of sleep, and one has eight and a half hours of sleep as maximum hours of sleep. Therefore, it can be affirmed that the statement that the difference between the maximum amount and the minimum number of hours is two and a half hours is false because between four hours and eight and a half hours there are four and a half hours of difference. So, the correct answer is False.

How do I find out if a function is in standard form
anzhelika [568]
Hey!

A function in slope-intercept form would look like y=mx+b; with the x and y values on the opposites of the equation.

A function in standard form would look like ax+by=c; with the x and y values on the same side of the equation.


Hope this helps!

Answer:

<h2><u><em>x = -2.27272727273</em></u></h2><h2><u><em>in fraction</em></u></h2><h2><u><em>x = -25/11</em></u></h2>

<u><em></em></u>

Step-by-step explanation:

Solve for X

6x+60x+150=0

66x = -150

x = -150 : 66

<u><em>x = -2.27272727273</em></u>

<u><em>in fraction</em></u>

<u><em>x = -25/11</em></u>
