It would be 6 haha I just took a test and got it right
Answer:
x=3
y=-1
Step-by-step explanation:
add
x+y+x-y=2+4
2x=6
x=6/2=3
3+y=2
y=2-3=-1
Answer: 1443
Step-by-step explanation:
Formula we use to find the sample size , if prior proportion is available :-
Given : Percent of the claims are covered : p= 60% =0.60
Margin of error : E=3% = 0.03
Critical value for 98 % confident :
Then , the required sample will be :
Hence, the required sample size = 1443
(1,0) as the x-intercept is when the equation goes through the x-axis and that y would be equal to 0
Here you'll need to do some online research, using "area of a cone" as your search term. There is a formula! But it's complicated.
Once you've found this formula online, substitute 17 feet for r. The height of the cone has to be calculated from the slant height (these are not the same):
(slant height)^2 = (12 feet)^2 = r^2 + h^2, where h is the actual height of the cone.
The area of the base is pi*r^2, or pi*17^2 square feet.
