Answer:

angle X = 136 degrees

Step-by-step explanation:

Given XYZW is a trapezoid means XY || WZ.

Given XW ≅ YZ means that base angles are equal

XWZ = YZW = 44

Since interior angles between parallel lines are supplementary,

angle X = YXW = 180-XWZ = 180-YZW = 180-angle Z = 180-44 = 136 degrees

In a random sample of 8 people, the mean commute time to work was 33.5 minutes and the standard deviation was 7.2 minutes. A 95

Elina [12.6K]

Answer: Margin of error = 6.58

Confidence interval = (26.91, 40.08)

Step-by-step explanation:

Since we have given that

Sample size n = 8

Sample mean = 33.5 minutes

Population standard deviation = 9.5 minutes

At 95% confidence interval,

α = 0.05

t = 1.96

So, Margin of error is given by

$t\times \dfrac{\sigma}{\sqrt{n}}\\\\=1.96\times \dfrac{9.5}{\sqrt{8}}\\\\=6.58$

Confidence interval would be

Lower limit:

$\bar{x}-6.58\\\\=33.5-6.58\\\\=26.91$

Upper limit:

$\bar{x}+6.58\\\\=33.5+6.58\\\\=40.08$

Hence, the interval would be (26.91, 40.08)

But at standard deviation 7.2 minutes, the confidence interval was (27.5, 39.5)

Confidence interval using the standard normal distribution is wider than the confidence interval using t distribution.

Santigo wants to paint the lateral surface of the foam pit red.How many square feet of the foam pit will be painted red?

Mnenie [13.5K]

Answer:

468 square feet.

Explanation:

The lateral surface of the foam pit can be calculated as:

Lateral Surface = Perimeter Base x Height

So, the perimeter of the base can be calculated as:

Perimeter = 12 ft + 24 ft + 12 ft + 24 ft

Perimeter = 72 ft

Therefore, the lateral surface is equal to:

Lateral surface = 72 ft x 6.5 ft

Lateral surface = 468 ft²

Then, 468 square feet will be painted red.
