Answer:
-14/9, -14
Step-by-step explanation:
y = -9x - 14
For x intercept, replace y with 0 and solve.
0 = -9x - 14
14 = -9x
-14/9 = x
- 1 5/9 = x
For y intercept, replace x with 0 and solve.
y = -9(0) - 14
y = -14
It will be 16[tex] 16^{2} = 256
Answer:
280
Step-by-step explanation:
Margin of error = critical value × standard error
Here, the margin of error is 2.
At 99% confidence, the critical value is z = 2.576.
The standard error is s / √n = 13 / √n.
2 = 2.576 (13 / √n)
2 = 33.49 / √n
√n = 16.74
n = 280.4
Rounded to the nearest person, the required sample size is 280.
Answer:
The mean absolute deviation (MAD) is 0
Step-by-step explanation:
20 + 16 + 21 + 16 + 22 + 16 + 15
= 126 ÷ 7 = 18
(20 - 18) + (16 - 18) + (21 - 18) + (16 - 18) + (22 - 18) + (16 - 18) + (15 - 18) =
2 +(-2) + 3 + (-2) + 4 + (-2) + (-3) = 0 ÷ 7= 0
The mean absolute deviation (MAD) is 0
1.75r +5=40
