Answer:
X = 64
Step-by-step explanation:
Comparing the two triangle put the right angle into consideration.
(17 + X)/(X + 8) = (X + 8)/X
Cross multiplying
X(17 + X) = (X + 8)(X + 8)
17X + X^2 = X^2 + 8X + 8X + 64
Collecting like terms
X^2 - X^2 + 17X - 8X - 8X = 64
X = 64
Answer:
Critical value t-score=2.701.
Step-by-step explanation:
When we calculate a confidence interval with an unknown population standard deviation, we estimate it from the sample standard deviation and use the t-score instead of the z-score.
The critical value for t depends on the level of confidence and the degrees of freedom.
If the sample size is 42, the degrees of freedom are:
For a confidence level of 99% and 41 degrees of freedom, the critical value of t is t=2.701.
Answer:
gallons of water will be needed to fill the pool 19388.16 gallons
Step-by-step explanation:
given data
Length of rectangular pool = 36 feet
Width of rectangular pool = 18 feet
1 cubic foot = 7.48 gallons water
solution
we consider here Depth of rectangular pool = 4 feet
so Volume of the pool = Length × Width × Depth ..............................1
put here value
Volume of the pool = 36 × 18 × 4
Volume of the pool = 2592 cubic feet
and
1 cubic feet = 7.48 gallons
so 2592 cubic feet will be
2592 cubic feet = 7.48 × 2592
2592 cubic feet = 19388.16 gallons
