The overhead reach distances of adult females are normally distributed with a mean of 205.5 and a standard deviation of 8.6 . a. Find the probability that an individual distance is greater than 218.00 cm. b. Find the probability that the mean for 15 randomly selected distances is greater than 204.00 c. Why can the normal distribution be used in part (b), even though the sample size does not exceed 30?
Answer:
a) 0.073044
b) 0.75033
c) The normal distribution can be used in part (b), even though the sample size does not exceed 30 because initial population size is been distributed normally , therefore, the mean of the samples will be normally distributed regardless of their size(meaning whether the sample size is less than or equal to or exceeds 30, the sample means the mean of the samples will be normally distributed regardless of their size).
Step-by-step explanation:
The overhead reach distances of adult females are normally distributed with a mean of 205.5 and a standard deviation of 8.6 .
a. Find the probability that an individual distance is greater than 218.00 cm.
We solve using z score formula
z = (x-μ)/σ, where
x is the raw score = 218
μ is the population mean = 205.5
σ is the population standard deviation = 8.6
For x > 218
z = 218 - 205.5/8.6
z = 1.45349
Probability value from Z-Table:
P(x<218) = 0.92696
P(x>218) = 1 - P(x<218) = 0.073044
b. Find the probability that the mean for 15 randomly selected distances is greater than 204.00
When = random number of samples is given, we solve using this z score formula
z = (x-μ)/σ/√n
where
x is the raw score = 204
μ is the population mean = 205.5
σ is the population standard deviation = 8.6
n = 15
For x > 204
Hence
z = 204 - 205.5/8.6/√15
z = -0.67552
Probability value from Z-Table:
P(x<204) = 0.24967
P(x>204) = 1 - P(x<204) = 0.75033
c. Why can the normal distribution be used in part (b), even though the sample size does not exceed 30?
The normal distribution can be used in part (b), even though the sample size does not exceed 30 because initial population size is been distributed normally , therefore, the mean of the samples will be normally distributed regardless of their size(meaning whether the sample size is less than or equal to or exceeds 30, the sample means the mean of the samples will be normally distributed regardless of their size).

What is inverse sine function?The inverse sine function (also called arcsine) is the inverse of sine function. Since sine of an angle (sine function) is equal to ratio of opposite side and hypotenuse, thus sine inverse of same ratio will give the measure of the angle.
According to the graph
Domain = [-1, 1]
Range = [-[tex]\frac{\pi }{2}[/tex], [tex]\frac{\pi }{2}[/tex]]
Restrict the domain of the sine-function y =sinx, so that it is one to one, and not infinite by setting an interval [-[tex]\frac{\pi }{2}[/tex], [tex]\frac{\pi }{2}[/tex]].
The restricted function passes the horizontal line test, therefore it is one to one .
Each range value (-1 to 1) is within the limited domain (-[tex]\frac{\pi }{2}[/tex], [tex]\frac{\pi }{2}[/tex]).
Inverse sine function:Inverse sine or arcsine is the inverse of the restricted sine function , y =sinx, [-[tex]\frac{\pi }{2}[/tex], [tex]\frac{\pi }{2}[/tex]].
The equation is y = [tex]sin^{-1}x[/tex] or y = arc sinx
Which also means , siny = x, where -[tex]\frac{\pi }{2}[/tex] ≤ y ≤ [tex]\frac{\pi }{2}[/tex], -1 ≤ x ≤ 1.
The coordinates of the inverse sine function (-1, -[tex]\frac{\pi }{2}[/tex]), (0, 0), (1, [tex]\frac{\pi }{2}[/tex]).
Thus, y = [tex]sin^{-1}x[/tex] function is represented in the graph.

The equation below describes a linear function. y=−2(x+1)+4 The range of the function is {−4,−2,4} . What is the domain of the function
9514 1404 393
Answer:
{-1, 2, 3}
Step-by-step explanation:
We need to find the values of x that correspond to these y-values.
{-4, -2, 4} = -2(x +1) +4 . . . substitute the range values for y
{2, 1, -2} = x +1 -2 . . . . . . .divide by -2
{2, 1, -2} = x -1 . . . . . . . . . simplify
{3, 2, -1} = x . . . . . . . . . . . add 1

Answer:
Slope= 4
Step-by-step explanation:
When you start at (0, 0) and then go to (1, 4), then you have to use the slope.
So, to figure out the slope, you have to do rise over run, rise/run.
So, as shown in the graph, the rise is 4 because the rise is the y so to get from 0 to 4, you have to add 4.
And the run, which would be the x side is 1 because to get from 0 to 1. You add 1.
This shows us that the slope is 4/1 which could be simplified to just 4.
if a(2x-3) = bx+5 then the solution for x in terms of a and b is
Answer:
x=(3a+5)/(2a-b)
Step-by-step explanation:
We spread the a to the 2x and -3 first,
2ax -3a= bx+5 5ax
By adding 3a, we pass the -3a over
2ax=bx+5+3aa bx+5+3aa
We'll pass the bx over the bx, then
2ax-bx=5+3aa-bx=5
Now we will party like this on the left side,
5+3a) x(2a-b)=5+3a)
Everything we have to do to find x is to separate both sides by (2a-b)
x=(3a+5)/=(3a+5)/ (2a-b)
Answer:
x = (5 + 3a)/(2a - b)
General Formulas and Concepts:
Pre-Algebra
Equality PropertiesStep-by-step explanation:
Step 1: Define equation
a(2x - 3) = bx + 5
Step 2: Solve for x
Distribute a: 2xa - 3a = bx + 5Add 3a on both sides: 2xa = bx + 5 + 3aSubtract bx on both sides: 2xa - bx = 5 + 3aFactor out x: x(2a - b) = 5 + 3aIsolate x: x = (5 + 3a)/(2a - b)On a piece of paper, graph:

What is a step function?The definition of a step function is a piecewise constant function with a finite number of parts.
The given function is [tex]f(x)=\begin{cases}{1\text{ if }-1 < x\leq0\\2\text{ if }0 < x\leq1\\3\text{ if }1 < x\leq2}\end{cases}[/tex].
Note that from -1 to 0 the value of f(x) is 1, therefore, its graph will be a horizontal line passing through y = f(x) = 1 from -1 to 0.
Similarly, the graphs of f(x) =2 from o to 1 and f(x) = 3 from 1 to 2 will look like this.
The graph of the function is shown.
The graph matches the graph in option (D), hence, option (D) is the correct answer.

I don't know how to answer question 1, but the answer from question 2 is x=5
Step-by-step explanation:
The triangle shown is an isosceles triangle because it has two congruent sides. The base angles of isosceles triangles are congruent so ∠y=∠x. since the ∠x is 52 the ∠y is also 52. We subtract the measure of angles x and y in order to find the measure of the third angle. 180-(52+52) or 180-104 is 76. this means that 14x=6=76. All we have to do to get the answer now is solve. 76-6 is 70 and 70 divided by 14 is 5. x=5.
