Answer: the correct answer is ( 7 * 5 ) + (7 * 9 )
Step-by-step explanation:
7 * ( 5+9) = (7 * __) + ( 7 * __) = ( 7 * 5 ) + (7 * 9 )
I think your answer is D because when you solve for K by simplifying both sides of the equation you get k>-10 so D would be your answer
Answer:
x = -9
Step-by-step explanation:
-18+24 = -2(x+6) Distribute and simplify
6 = -2x-12 Add 12 to both sides
18 = -2x Divide by -2 on both sides
-9 = x Here's your answer
Hope this helps! :D
Answer: Option 'b' is correct.
Step-by-step explanation:
Since we have given that
s = 0.81
n = 31
We need to find the 93% confidence interval to estimate the true standard deviation.
degrees of freedom = df = n-1=30
Here, α = 0.93
1-α=0.07
so,
and
So, we will use "Chi square distribution"
So, the interval would be
Hence, 93% confidence interval would be (0.6581,1.058).
Therefore, Option 'b' is correct.
