I will need a picture. Then I will try to answer.
Step-by-step explanation:
Answer: u = (41.659, 36.341)
Step-by-step explanation:
Constructing a 90% confidence interval for mean is given by the formulae below.
u = x + Zα/2 * σ/√n...... This is the upper limit
u = x - Zα/2 * σ/√n........ This is the lower limit.
u = population mean
x = sample mean = 39
σ = population standard deviation = 9
Zα/2 = Z score for a two tailed test with an a level of significance = 1.645 ( for 90% confidence level)
Upper limit
u = 39 + 1.645 * (9/√31)
u = 39 + 1.645 * (1.616)
u = 39 + 2.6590
u = 41.659
Lower limit
u = 39 - 1.645 * (9/√31)
u = 39 - 1.645 * (1.616)
u = 39 - 2.6590
u = 36.341
Answer:
8 1/8 units^3
Step-by-step explanation:
This figure is a rectangular prism, and the volume of a rectangular prism is given by the formula:
lwh
But since we have the area of the base snd the height of the figure, there is also one formula that we can use to find the volume:
bh
Which means area of base times the height.
USE THE FORMULA bh:
16 1/4 x 1/2
= 65/4 x 1/2
= 65/8
SIMPLIFIED: 8 1/8
Volume is measured in cubic units
SO YOUR ANSWER IS 8 1/8 units^3
The answer is 7/16 because if you turn the denominator into a bigger number so you can get the answer, it becomes 14/16 and half of that is 7/16.
