Answer:
The P-value is 80.23%
Step-by-step explanation:
Given;
number of samples, n = 64
sample mean, X = 1.03
standard deviation, σ = 0.189
[tex]sample \ mean \ (X) = \frac{Sum \ of \ samples}{number \ of \ samples \ -1} \\\\1.03 = \frac{Sum \ of \ samples}{64 -1}\\\\Sum \ of \ samples = 1.03(63)\\\\Sum \ of \ samples = 64.89[/tex]
Population mean (μ) is given as;
[tex]\mu = \frac{Sum \ of \ samples}{number \ of \ samples} \\\\\mu = \frac{64.89}{64} \\\\\mu = 1.01 \\[/tex]
The z-score is given as;
[tex]z = \frac{X -\mu}{\frac{\sigma}{\sqrt{n} } }\\\\z = \frac{1.03 -1.01}{\frac{0.189}{\sqrt{64} } }\\\\z = \frac{0.02}{\frac{0.189}{8} }\\\\z = 0.8466 \\[/tex]
z ≅ 0.85
From the z-table, the P-value at the given z-score is 0.8023 = 80.23%;

Find a X
HELP IM TAKING A TIMED TEST 51 POINTS
Answer:
60
Step-by-step explanation:
Answer:
x = 55, upper left angle is 135, down left angle is 55
Step-by-step explanation:
The shape is a quadrilateral and all of the quadrilaterals angles added together is 360 degrees and that little square at the bottom right of the shape means it's a right angle and a right angle is 90 degrees so:
4x - 85 + 80 + x + 90 = 360
rearrange to make it easier to add like terms
4x + x - 85 + 80 - 90 = 360
add like terms
5x + 85 = 360
subtract 85 from both sides
5x = 275
divide both sides by 5
x = 55
Plug 55 into 4x - 85 to find the angles
4(55) - 85 = 135

Jeremy’s house is 45 feet wide. In a photograph the width of the house was 2.5 inches, and its height was 2 inches. What is the actual height of Jeremy’s house?
Hello!
[tex]\large\boxed{36 ft}[/tex]
We can use proportions to solve for the actual height of his house. Remember, we must convert from inches to feet:
1 foot = 12 inches
45 ×12 = 540 inches
Set up a proportion:
[tex]\frac{2.5}{540} = \frac{2}{x}[/tex]
Cross multiply:
2.5 · x = 540 · 2
2.5x = 1080
Divide both sides by 2.5:
x = 432 inches
Convert back to feet:
432 / 12 = 36 feet
