A z-table is also known as the standard normal distribution table. The percentage of the population that would fall in the 10 to 22 mm Hg range is 0.9386.
What is a Z-table?A z-table also known as the standard normal distribution table, helps us to know the percentage of values that are below (or to the left of the Distribution) a z-score in the standard normal distribution.
Given the mean and the standard deviation are 16mmHg and 3.2 mmHg, therefore, the percentage of the population whose blood pressure will fall in the range of 10 to 22 mm Hg are,
[tex]P(10 < x < 22) = P(\dfrac{10-16}{3.2} < Z < \dfrac{22-16}{3.2})[/tex]
[tex]= P(-1.875 < Z < 1.875)\\\\=P(Z < 1.875)-P(Z < -1.875)\\\\= 0.9693-0.0307\\\\= 0.9386[/tex]
Hence, the percentage of the population that would fall in the 10 to 22 mm Hg range is 0.9386.

Suppose that you are a member of the typical American household and your family carries a credit card debt of
$7942. Use the TVM (Time-Value-of-Money) Solver to model a few credit card scenarios. (Note: Use months
rounded to the nearest hundredths on all calculations.)
1. If the average annual interest rate is 17.11%, how many months will it take the average American family
to pay off their debt of $7,942 if they make a minimum payment of $175 each month and no additional
purchases are made?
2. How much interest did you pay during this time?
1. At an annual interest rate of 17.11%, an average family needs 74 months to settle $7,942 at a $175 monthly payment.
2. The total interest is $4,932.10.
What is a monthly payment?The monthly payment is the amount paid each month to settle the loan within its maturity period.
The monthly payment can be computed using an online finance calculator.
We can also determine the period of payment using the same online finance calculator as below.
Data and Calculations:I/Y (Interest per year) = 17.11%
PV (Present Value) = $7,942
PMT (Periodic Payment) = $-175
FV (Future Value) = $0
Results:
N = 73.566
Sum of all periodic payments = $12,874.10
Total Interest = $4,932.10
Thus, while it will take 74 months for the average American family to pay off the loan of $7,942 with a monthly payment of $175 at 17.11% interest, the total interest paid is $4,932.10.

What is the area of the shaded sector of Point B below?
Answer:
A) 175π / 9 squared inches,
Step-by-step explanation:
Radius = 10 inches
AB = BD = 10 = radius
Triangle ABD is isosceles
Angle DAB = Angle BDA = 35 degrees,
Base angles theroem
35 + 35 + x = 180, angles in triangle
x = 180 - 70
x = 110 degrees
Angle DBC is supplementary with ABD
110 + x = 180
x = 70
70 degrees is angle for the sector
70 is 70/360, 7/36 of the circle
The area will also be 7/36 of the circle area
Area of circle = πr^2
Area = 100π
Area of sector = (100π * 7) / 36
Area of sector = 700π / 36
Simplified area = 175π / 9 squared inches
Solve the equation on the
interval [0,21).
2 csc x + 17 = 15 + CSC X
Answer:
7π/6, 11π/6
Step-by-step explanation:
2cscx + 17 = 15 + cscx
1. Subtract cscx and 17 from both sides ⇒ cscx = -2
2. cscx = 1/sinx ⇒ 1/sinx = -2
3. Multiply by sinx and divide by -2 ⇒ sinx = -1/2
When is sinx equal to -1/2? ⇒ 7π/6, 11π/6
The solution of the equation 2cosec x+17 = 15+cosec x is 7π/6 and 11π/6.
What is the solution of the given equation in the interval [0, 2π)?Given:
The equation which is given is 2Cosec x + 17 = 15 + Cosec x.The interval is [0,2π).Find:
The solution of the given equation.Solution:
2Cosec x + 17 = 15 + Cosec x
⇒ 2Cosec x - Cosec x = 15 - 17
⇒ Cosec x = -2
Now, 1/sinx = -2
⇒ sinx = -1/2
we know, sin 30° = 1/2
Since, sinx is negative,
x will be in 3rd and 4th quadrant.
value in 3rd quadrant = 180° + 30° = 210°
value in 4th quadrant = 360° - 30° = 330°
So, x = 210° = 210 * π/180 = 7π/6
Also, x = 330° = 330 * π/180 = 11π/6

Describe a data set that has the same mean, median, and mode.
I not really understanding this question could somebody help
Answer: Okay, so you probably already know this but,
The mean - is the same as the average value of a data set and is found using a calculation. Add up all of the numbers and divide by the number of numbers in the data set.
Add up all of the numbers and divide by the number of numbers in the data set. The median is the central number of a data set. Arrange data points from smallest to largest and locate the central number.
The mode of a data set is the number that occurs most frequently in the set. To easily find the mode, put the numbers in order from least to greatest and count how many times each number occurs. The number that occurs the most is the mode!
Step-by-step explanation:
In a perfectly symmetrical distribution, the mean and the median are the same. This example has one mode (unimodal), and the mode is the same as the mean and median. In a symmetrical distribution that has two modes (bimodal), the two modes would be different from the mean and median.
hope this helps you!!
Answer:
One of the many examples is {0, 0, 0, 0, 0}
Step-by-step explanation:
The mean is the average of a data set.
The median is the number in the middle (or between the 2 middle numbers) of a data set that is placed from least to greatest.
The mode is the value that shows up the most times in the data set.
A few examples of a set with the same mean, median, and mode could be any number repeated in a data set:
{0, 0, 0, 0, 0}
This would work because the mean is 0, the median is 0, and the mode is 0.

Enter your answer as a decimal in the box. Round only your final answer to the nearest tenth.
in²
The figure contains a triangle. One side is 13 inches. A second side is 7.5 inches. The angle between the given sides is 94 degrees.
Answer:
Area = 48.6 in²
Explanation:
The area of the triangle can be calculated using the side-angle-side method as follows:
Area = 0.5 * first side * second side * sin(angle included between the two sides)
This rule is illustrated in the attached image.
Now, we have:
first side = 13 in
second side = 7.5 in
The angle included between the two sides = 94 degrees
The given angle is included between the two given sides, therefore, we can apply the above rule to get the area.
Area of triangle = 0.5 * 13 * 7.5 * sin(94)
Area of triangle = 48.63 which is approximately 48.6 in²

Answer: The vector is < 2, 5 >
==========================================================
Explanation:
Label the initial point (1,-7) as point P and (3,-2) as point Q.
The x coordinate of P is 1The x coordinate of Q is 3This is a change of +2, meaning we move 2 units to the right.
Therefore, the x component of the vector is +2 or simply 2.
The y coordinate of P is -7The y coordinate of Q is -2This is a change of +5 when moving from P to Q. We have moved 5 units up. The y coordinate of the vector is +5 or simply 5.
Overall, the vector is < 2, 5 > which tells the reader "move 2 units to the right and 5 units up.

the negative sign in front of x^2 is also -1, which is the "a". A controls if the parabola will opek up or down, and the width of the function. In this problem, the parabola opens down. the -3 corresponds to "k" in vertex form. K is the vertical shift or the y coordinate of the vertex. If k is positive it moves up, and if it is negative it moves down. Because of the -3, the vertex of the parabola will move down 3 units on the y-axis.
