Answer:
1. χ² = 18.548
2. χ² = 23.685
Step-by-step explanation:
1. Confidence level is 99% (α = 0.01), but we're only interested in the left half, so α/2 = 0.005. Degrees of freedom are 7−1 = 6. Looking up in a chi square table, χ² = 18.548.
2. Confidence level is 90% (α = 0.10), but we're only interested in the right half, so α/2 = 0.05. Degrees of freedom are 15−1 = 14. Looking up in a chi square table, χ² = 23.685.
The answers to this question are y = -3x - 2 and 3x + y = -2
y + 5 = -3(x - 1)
y + 5 = -3x + 3
y = -3x - 2 --> a choice
3x + y = -2 -- > a choice
Answer:
The land which are used for exhibits are <u>89 acres</u> (approximately).
Step-by-step explanation:
Given:
Village is spread across 240 acres of land. 37% of land is used for the exhibits.
Now, we have to find acres of land which are used for exhibits.
So, here it is given that land used for exhibits is 37%, and we have to calculate the quantity from the percentage given:
According to question:
37% of 240 acres of land.
So, the land used for exhibits are 88.80 acres.
Therefore, the land which are used for exhibits are <u>89 acres </u>(approximately).
1.
A. This statement is wrong because the prediction is valid, not valid.
B. Refer to A.
C.This statement is valid, yet explains the prediction incorrectly.
[D.] This statement is correct because 50 x 6 = 300, therefore 20% of 300 is 60.
2.
A. This is incorrect because it equals 125%
B. This is also incorrect, it equals 12.5%
C. Refer to B
[D.] This is correct, it equals 1.14%, which is less than 1.25%
Answer:
it equals x=10 so i guess it's B
