Answer:
(53.3; 56.1)
Step-by-step explanation:
Given that:
Sample size, n = 41
Mean, xbar = 54.7
Standard deviation, s = 5.3
Confidence level, Zcritical at 90% = 1.645
Confidence interval :
Xbar ± Margin of error
Margin of Error = Zcritical * s/sqrt(n)
Margin of Error = 1.645 * 5.3/sqrt(41)
Margin of Error = 1.362
Lower boundary = 54.7 - 1.362 = 53.338
Upper boundary = 54.7 + 1.362 = 56.062
(53.3 ; 56.1)
Left 7 units and up 3 units
Given:
Triangular prism.
Base area : 37.4 square yards
height : 5 yards
To find the volume of the ramp based on the given figures, we simply multiply the base area by the height.
Volume = base area * height
V = 37.4 square yards * 5 yards
V = 187 cubic yards.
The volume of the triangular prism-shaped ramp is 187 cubic yards.
