The following histogram shows the relative frequencies of the height recorded to the nearest inch of population of women the mean of the population is 64.97 inches and the standard deviation is 2.66 inches
(a) Based on the histogram, what is the probability that the selected woman will have a height of at least 67 inches? Show your work
Answer:
0.22268
Step-by-step explanation:
z-score is z = (x-μ)/σ,
where x is the raw score
μ is the population mean
σ is the population standard deviation.
(a) Based on the histogram, what is the probability that the selected woman will have a height of at least 67 inches? Show your work
At least means equal to or greater than 67 inches
z = 67 - 64.97/2.66
z = 0.76316
P-value from Z-Table:
P(x<67) = 0.77732
P(x>67) = 1 - P(x<67) = 0.22268
The probability that the selected woman will have a height of at least 67 inches is 0.22268

If I dilate a 2x2 square by a scale factor of 3, what will be the new area?
Answer:
36 square units
Step-by-step explanation:
A 2x2 square has sides that are 2 units long.
When you dilate by a factor of 3, each side has a length 3 times the original length. 2 * 3 = 6. Each side is now 6 units long.
area = side * side = 6 units * 6 units = 36 units^2

On the graph of f(x)=sinx and the interval [2π,4π), for what value of x does f(x) achieve a minimum?
Answer:
Step-by-step explanation:
The minimum value of sinx is -1 when x = 3π/2, 7π/2, ...
In [2π, 4π), x = 7π/2
The function f(x)=sin(x) achieves its minimum value of -1 at x=3π.
The function f(x)=sin(x) is a periodic function with a period of 2π, meaning it repeats every 2π units. Within the interval [2π,4π), which is one period of the function, the minimum value of sin(x) occurs at x=3π.
This is because at x=3π, the sine function reaches its minimum value of -1. As you move further away from 3π, the sine function starts increasing again.
So, within the interval [2π,4π), the function f(x)=sin(x) achieves its minimum value of -1 at x=3π.

find the slope of the line that passes through the points A(-6,2) and B(5,-1).
A 3/11
B -3/11
C -1
D -11/3
Answer:
[tex]\boxed{\sf{m=-\dfrac{3}{11} }}[/tex]
Step-by-step explanation:
You simply need to use a slope formula that passes through the points in order to solve this problem.
Slope:
[tex]\sf{\dfrac{Y_2-Y_1}{X_2-X_1}=\dfrac{RISE}{RUN} }[/tex]
y2=(-1)
y1=2
x2=5
x1=(-6)
Rewrite the problem down.
[tex]\sf{\dfrac{-1-2}{5-(-6)}=\dfrac{-1-2}{5+6}=\dfrac{-3}{11}=\boxed{\sf{-\dfrac{3}{11} }}}[/tex]
-3/11
Therefore, the slope is -3/11, which is our answer.

The length of a rectangular parking area is two times the width. The perimeter is 90 ydFind the length and width of the parking area.
Question :-
The Length of a Rectangular Parking Area is Two times the Width. The Perimeter is 90 yards . Find the Length and Width of the Parking Area .Answer :-
Length of Parking Area is 15 yards .Width of Parking Area is 30 yards .Explanation :-
As per the provided information in the given question, we have been given that the Length of a Rectangular Parking Area is Two times the Width . The Perimeter is given as 90 yards . And, we have been asked to calculate the Length and the Width .
Let the Values be like :-
Length = xBreadth = 2xNow, for calculating the Length & Width , we will use the Formula :-
[tex] \bigstar \: \: \boxed{ \sf{ \: Perimeter \: _{Rectangle} \: = \: 2 \times [ \: Length + Breadth \: ] \: }} [/tex]
Therefore , by Substituting the given values in the above Formula :-
[tex] \dag \: \: \: \sf{Perimeter \: _{Rectangle} \: = \: 2 \: \times \: [ \: Length \: + \: Breadth \: ]} [/tex]
[tex] \longmapsto \: \: \: \sf { 90 \: = \: 2 \: \times \: [ \: x \: + \: 2x \: ]} [/tex]
[tex] \longmapsto \: \: \: \sf {90 \: = \: 2 \: \times \: [ \: 3x \: ]} [/tex]
[tex] \longmapsto \: \: \: \sf {90 \: = \: 2 \: \times \: 3x } [/tex]
[tex] \longmapsto \: \: \: \sf {90 \: = \: 6x } [/tex]
[tex] \longmapsto \: \: \: \sf {x \: = \: \dfrac { \: 90 \: }{6}} [/tex]
[tex] \longmapsto \: \: \textbf {\textsf{ x \: = \: 15}} [/tex]
Therefore :-
[tex] \Longrightarrow \: [/tex] Length = x = 15 yards
[tex] \Longrightarrow \: [/tex] Breadth = 2x = 2 × 15 = 30 yards
[tex] \underline {\rule {210pt} {4pt}} [/tex]

If h(x) = 2x+3 and g(x) = 3x-2, find the value of goh(5).
Answer:
h(x)=2x+3
g(x)=3x-2
First we will find goh(x) then we will put the value of x i.e 5.
goh(x)= 3(2x+3)-2
goh(x)=6x+9-2
goh(x)=6x+7
Now put the value of x, we get
goh(5)=6(5)+7
We get the answer 37

2. Consider the line
y = 3/5x -8
What is the
slope of the line perpendicular to this line?
Answer:
The slope of the perpendicular line is [tex]-\frac{5}{3}[/tex]
Step-by-step explanation:
The product of the slopes of the perpendicular lines is -1That means to find the slope of a perpendicular line to a given line, reciprocal its value, and reverse its signEx: If the slope of a line is [tex]\frac{1}{3}[/tex], then the slope of the line perpendicular to it is -3Let us solve the question
∵ The equation of a line is y = [tex]\frac{3}{5}[/tex] x - 8
→ The form of the equation is y = m x + b, where m is the slope
∴ The slope of the line is [tex]\frac{3}{5}[/tex]
→ To find the slope of the line perpendicular to it reciprocal it and
reverse its sign
∵ The reciprocal of [tex]\frac{3}{5}[/tex] is [tex]\frac{5}{3}[/tex]
→ Change its sign from positive to negative
∴ The slope of the perpendicular line is [tex]-\frac{5}{3}[/tex]

Identify the mistake and write down the correct answe 2/5 + 1/3 = 3/8
Answer:
The mistake is that the denominators are not the same in these fractions so you cannot add them yet. So, you would have to change the denominators to be the same before adding. The denominators I chose is 15, 2/5 times 3 which is equal to 6/15 and 1/3 times 5 which is equal to 5/15. Now, we can add 6/15 and 5/15 which is equal to 11/15!
