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
Step-by-step explanation:
Let's represent the two integers with the variables
and
.
From the problem statement, we can create the following two equations:


With the first equation, we can subtract
from both sides to isolate the
variable to the left-hand side:

Now that we have a value for
, we can plug it into the second equation and solve for
:


Now, let's move everything to one side of the equation:

Factoring this quadratic will give us two values for
:


Since we now know
, we can plug this back into either of the original equations to get a value for
, which will be
.
So the two numbers that sum to
and have a product of
are
.
This is an acute scalene triangle
The triangle is acute since all three angles (58, 57, 65) are less than 90 degrees
The triangle is scalene as the angles are all different. So this leads to the sides being different lengths. No two sides are the same length.
Answer: 7.5
Step-by-step explanation:
use pythagorean theorem
13^2 + b^2 = 15^2
- 13^2
b^2 = 56 - square root
= 7.5
