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.
Step-by-step explanation:
-4x - 28
x = -28 + 4
x = -24
I HOPE THIS IS CORRECT IN ONLY THIS WAY SORRY IF IT IS WRONG
CAN YPU MARK ME AS BRAINLIEST
Answer:
C.
is greater than zero.
Step-by-step explanation:
We know that graph is obtained from the function of the form
. According to the graph and if
, we find that:
(1)
(2)
By (1) and (2):


Hence, correct answer is C.
The sequence is
740, 707.60,675.20,642.80,...
Here first term is 740, and common difference, d is

Now we use the formula of nth term, which is

Substituting the values of a,n and d, we will get

Correct option is the second option .
