If a man is 6 feet 2 inches tall, his z-score is equal to 1.82.
If a woman is 5 feet 10 inches tall, her z-score is equal to 2.92.
The 5 feet 10 inches American woman is relatively taller.
What is a z-score?In a normal distribution, the z-score of a given sample score can be calculated by using this formula:
Z-score = (x - μ)/σ
Where:
σ represents the standard deviation.x represents the sample score.μ represents the mean score.Next, we would convert the height in feet to inches as follows:
American man = 6 × 12 + 2 = 74 inches.
American woman = 5 × 12 + 10 = 70 inches.
For the American man's z-score, we have:
Z-score = (74 - 69.2)/2.64
Z-score = 4.8/2.64
Z-score = 1.82
For the American woman's z-score, we have:
Z-score = (70 - 64.2)/2.53
Z-score = 5.8/2.53
Z-score = 2.92
Therefore, the 5 feet 10 inches American woman is relatively taller because she has a higher z-score (2.92 > 1.82).

Step-by-step explanation:
Zack is on his school's color guard and is practicing throwing and catching his flag. He throws the flag into the air from a height of 5 feet at a velocity of 30 feet per second. After the flag starts to come back down, he catches it 7 feet above the ground.
To the nearest tenth of a second, how long is the flag in the air before Zack catches it?
Hint: Use the formula h=16t2+vt+s.
The Nearest tenth of a second, the flag is in the air for approximately 0.1 seconds before Zack catches it.
To determine the time the flag is in the air before Zack catches it, we can use the kinematic equation for vertical motion:
h = 16t^2 + vt + s
Where:
h is the height of the flag,
t is the time in seconds,
v is the initial vertical velocity of the flag,
s is the initial height of the flag.
In this case, the flag is thrown into the air from a height of 5 feet (s = 5) with an initial vertical velocity of 30 feet per second (v = 30). Zack catches it at a height of 7 feet (h = 7).
We can rewrite the equation as:
7 = 16t^2 + 30t + 5
To find the time (t) when the flag is at a height of 7 feet, we can rearrange the equation and solve for t. However, since this is a quadratic equation, we can also use the quadratic formula.
The quadratic equation in this case is:
16t^2 + 30t + 5 - 7 = 0
16t^2 + 30t - 2 = 0
Now, we can use the quadratic formula:
t = (-b ± √(b^2 - 4ac)) / (2a)
Applying the values from the quadratic equation, we have:
t = (-30 ± √(30^2 - 4 * 16 * (-2))) / (2 * 16)
Simplifying further:
t = (-30 ± √(900 + 128)) / 32
t = (-30 ± √1028) / 32
Using a calculator, we find two solutions:
t ≈ -1.08 seconds or t ≈ 0.06 seconds
Since time cannot be negative in this context, we discard the negative solution.
Therefore, to the nearest tenth of a second, the flag is in the air for approximately 0.1 seconds before Zack catches it.

A rainstorm in Portland, Oregon, wiped out the electricity in 7% of the households in the city. Suppose that a random sample of 50 Portland households is taken after the rainstorm.
A Estimate the number of households in the sample that lost electricity by giving the mean of the relevant distribution (that is, the expectation of the relevant random variable). Do not round your response.
B Quantify the uncertainty of your estimate by giving the standard deviation of the distribution. Round your response to at least three decimal places.
The estimate the number of households in the sample that lost electricity by giving the mean of the relevant distribution is 3.5 and the quantify the uncertainty of your estimate by giving the standard deviation of the distribution is 1.64.
As per the question given,
Imagine you're in Portland, Oregon, and a rainstorm has just passed through, causing a power outage in 7% of the households in the city. Now suppose you take a random sample of 50 households to see how many of them were affected by the outage. How can you estimate the number of households in the sample that lost electricity, and how certain can you be of your estimate?
By using the binomial distribution with parameters n=50 and p=0.07, we can calculate that the average number of households in a random sample of 50 that lost electricity is 3.5. This means that we can expect around 3 or 4 households in the sample to have been affected by the power outage on average.
But we don't just want to know the average - we also want to know how much variation we can expect in our sample. By calculating the standard deviation of the distribution, we can see that the number of households that lost electricity in a sample of 50 is likely to vary by around 1.64 on average.
Of course, it's important to keep in mind that these calculations assume that our sample is random and representative of the population of Portland households, and that there are no dependencies or correlations between households that could affect the probability of losing electricity during the rainstorm. But armed with this information, we can make a reasonable estimate of the number of households affected by the power outage and have a sense of how uncertain our estimate is likely to be.

Use this data set to answer all questions on this page.
513, 490, 496, 380, 490, 513, 503, 513, 500, 492
Question 1 Which of the following would be APPROPRIATE measure(s) of center. (1)Mean (2)Median (3) Mode. Question 2 Find the standard deviation. Round your answer to the tenths place(one decimal place)
Answer:
Question 1: The appropriate measures of center for this data set would be (1) Mean and (2) Median. There is no mode in this data set as there are no repeating values.
Question 2: To find the standard deviation, we first need to find the mean:
Mean = (513 + 490 + 496 + 380 + 490 + 513 + 503 + 513 + 500 + 492) / 10 = 494.0
Next, we find the difference between each data point and the mean:
(513 - 494.0), (490 - 494.0), (496 - 494.0), (380 - 494.0), (490 - 494.0), (513 - 494.0), (503 - 494.0), (513 - 494.0), (500 - 494.0), (492 - 494.0)
19, -4, 2, -114, -4, 19, 9, 19, 6, -2
Then we square each difference:
361, 16, 4, 12996, 16, 361, 81, 361, 36, 4
The sum of these squared differences is:
361 + 16 + 4 + 12996 + 16 + 361 + 81 + 361 + 36 + 4 = 14136
To find the variance, we divide the sum of squared differences by the number of data points minus one:
Variance = 14136 / 9 = 1570.7
Finally, we find the standard deviation by taking the square root of the variance:
Standard deviation = √1570.7 ≈ 39.6 (rounded to the tenths place)

We can use a system of equations to solve x + 8 = 12 and the both equations are true, we can conclude that the number is 4.
What is system of equations ?
A system of equations is a collection of two or more equations that are solved simultaneously to find the values of the variables that satisfy all of the equations. Each equation in the system represents a constraint on the variables, and the solution to the system is the set of values for the variables that satisfy all of the constraints.
We can use a system of equations to solve this problem. If the number in question is called "x", we can write:
x + 8 = 12
y
3 * x = 12
Now we can solve for "x". First, we will isolate "x" from the first equation:
x + 8 = 12
x = 12 - 8
x = 4
Now we can check if this result also satisfies the second equation:
3 * x = 12
3 * 4 = 12
Since both equations are true, we can conclude that the number is 4.

Given m∥n, find the value of x.
Answer:
x = 11
Step-by-step explanation:
The two angles measuring (7x + 14)° and (9x - 8)° are corresponding angles, which are always congruent to each other and thus equal to each other.
Step 1: Thus, we can find the value of x by setting the two angles equal to each other:
7x + 14 = 9x - 8
7x + 22 = 9x
22 = 2x
11 = x
Optional Step 2: We can check that we've found the correct answer by plugging in 11 for x in both (7x + 14) and (9x - 8) and checking that we get the same number:
7(11) + 14 = 9(11) - 8
77 + 14 = 99 - 8

My checking account balance was $443 on February 1st and $872 on February 7th. Show the rate of change
Answer:
$61.29 per day.
Step-by-step explanation:
Checking account balance on February 1st: $443
Checking account balance on February 7th: $872
Difference in balances: $872 - $443 = $429
Number of days between February 1st and February 7th: 7 days
Rate of change = Difference in balances / Number of days
Rate of change = $429 / 7 days
To find the rate of change per day, divide the difference in balances by the number of days:
Rate of change = $429 / 7 days ≈ $61.29 per day
Therefore, the rate of change in your checking account balance during that period was approximately $61.29 per day.
∠A and ∠B are complemntry angles. If m∠A = (3x+18) and m∠B = (2x+17) then find the measure of ∠A
Work Shown:
Complementary angles add to 90 degrees.
A+B = 90
(3x+18)+(2x+17) = 90
5x+35 = 90
5x = 90-35
5x = 55
x = 55/5
x = 11
Then we can determine each angle:
angle A = 3x+18 = 3*11+18 = 33+18 = 51 degrees is the final answerangle B = 2x+17 = 2*11+17 = 22+17 = 39 degreesAs a check: A+B = 51+39 = 90 to confirm the answer.
