Answer:
Step-by-step explanation:
When adding rational numbers, if the denominator is the same you simply keep the denominator (bottom of fraction) as it is and apply the operation given to the numerator ( top of fraction )
So we have 
==> remove parenthesis and apply signs
==> simplify numerator by combining like terms
and we are done!
Note:
like terms are terms with the same variable and exponent
An example of like terms are 6x^7 and 3x^7 as they have x as a variable and a power of 7
The like terms being combined here were (6x² and 4x²) and (5 and -2)
The answer is A; 1/2. You add 1 1/2 and 1 1/2 together to get 3. Then you subtract 3 1/2 and 3 to get your answer 1/2. I hope that helps!
Answer:
B
Step-by-step explanation:
If you plug in 5 1/3 to the equation, the result is 6, meaning that the point lies on the line.
Answer:
if thisa is a triangle then 180-30+30 = 120 degree and we say all angles on a triangle add up to 180
Then reaply the rule changing 180 to 360 on all 4 sided shapes
180(n-2) to all other shapes.
ie) pentagon 180(n-2) = 540
continue with 540-30-30 = 480 etc....

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
