Answer:
Step-by-step explanation:
using the y=mx+b equation, where m=slope and b=y-intercept, we can place our known slope and y-intercept to form our answer, :-) hope this helped!
Answer: the margin of error is 0.02
Step-by-step explanation:
Confidence interval for population proportion is written as
Sample proportion ± margin of error
If the confidence interval for this population proportion is (0.52, 0.56.), it means that the lower boundary is 0.52 and the upper boundary is 0.56
Let x represent the sample proportion and y represent the margin of error. Therefore,
x - y = 0.52
x + y = 0.56
Subtracting the second equation from the first equation, it becomes
- 2y = - 0.04
y = - 0.04/-2
y = 0.02
This is a square root problem since the patio is square.
A of a square is L x W or L^2 or W^2 - it's all the same.
So find the square root of 220 feet.
14.8323 We are to round to nearest hundreth which is the second position right of decimal. Look at the number to the right of that position.
It is a 2. So we do not round the number up.
14.83 is the rounded sq. ft of each side.
Check it!
14.83^2 = 219.92 Because we rounded, this number is not exact, but close.
Answer:
y = -3x - 5
Step-by-step explanation:
y - 1 = -3 (x + 2)
y - 1 = -3x - 6
y = -3x -5
