Answer:
Answer: (7,-2)
Step-by-step explanation:
Look at the formula
1) (x – h)^2 + (y – k)^2 = r2
the center is described by (h,k)
now look at
(x – 7)^2 + (y +2)^2 = 25
here h=7
but k= -2 because is (y+2) =(y-(-2))
Answer:
2nd option, x > 1.10
Step-by-step explanation:
Add 5 to both sides,
Divided both sides by 7,
Apply Exponent Rule,
x > ln(3) or x > 1.09861

Answer: The difference between M and mu is due to the sampling error is <u>-6.59
.</u>
Step-by-step explanation:
As per given:
in population, the average number of minutes spent in active play on weekends is μ = 65.87
In sample, the average number of minutes the children spend in active play on weekends is M = 59.28
Now, the difference between M and μ is due to the sampling error is M- μ
= 59.28 - 65.87
= -6.59
So, the difference between M and mu is due to the sampling error is <u>-6.59
.</u>
This is how you work it out:
u + xy
Plug in your numbers that you know:
20 + 9 * 8
20 + 72
92
