X should be 1/2
The way I solved this was by viewing 1/8. I grabbed 8 from the equation and did 8^(1/3) which got me 2. In addition both 1/8 and 1/2^3 in decimal form are both 0.125
Answer:
7 gallon
Step-by-step explanation:
Divide the space that needs paints by how much space has been painted
2500/785 = 3.18
Then double that because it takes 2 gallons to paint every 785 square feet
3.18 x 2 = 6.36
You would need 6.36 gallons of paint, which would round up to 7 because you cannot buy 0.36 of a gallon
Answer:
a
Step-by-step explanation:
Step-by-step explanation:
a. The mean can be found using the AVERAGE() function.
x = 272.7
b. The standard deviation can be found with the STDEV() function.
s = 39.9
c. The t-score can be found with the T.INV.2T() function. The confidence level is 0.04, and the degrees of freedom is 26.
t = 2.162
d. Find the lower and upper ends of the confidence interval.
Lower = 272.7 − 2.162 × 39.9 = 186.5
Upper = 272.7 + 2.162 × 39.9 = 358.9
Answer: 
Step-by-step explanation:
Since we have given that
Now, we know the rule for summation , we'll apply this ,
Now, it becomes geometric progression, so we us the formula for sum of terms in g.p. which is given by
So, our equation becomes ,
Hence ,
