Answer:
y=(x+5)²/6 + 1/3
Step-by-step explanation:
Use the distance formula to plug in the values you know:
√(y+1)² =√(x+5)² +( y-2)²
the square roots cancel out
(y+1) ²= (x+5)² +(y-2)²
(y+1) (y-1)= (x+5)² + (y-2) (y-2)
y²+2y+1= (x+5)² + y² -4y+4
the y² cancel out
2y+ 4y = (x+5)² + 4-1
6y= (x+5)² +3
y= (x+5)² /6+ 1/3
D and E. An acute angle is any angle that is less than 90(a right angle). A is an obtuse angle(more than 90). And B + C are right angles. Hope this helps you!

Answer:
a) 49%
b) 49
Step-by-step explanation:
We have that:
The proportion of adult women in a certain geographical region is approximately 49%.
a) What proportion of women in the sample of 100100 would you expect to see?
The same as the region, that is 49%.
b) How many women, on average, would you expect to find in a sample of that size?
There are 100 people. In the region, the proportion of women is 49%.
So, in a sample of 100 people, you would expect to find 49 women.
