Using the normal distribution, it is found that 0.13% of American women CAN NOT use the bicycles designed by this company.
What is Normal Probability Distribution?The z-score of a measure X of a normally distributed variable with mean and standard deviation is given by:
[tex]z=\dfrac{x-\mu}{\sigma}[/tex]
The z-score measures how many standard deviations the measure is above or below the mean.Looking at the z-score table, the p-value associated with this z-score is found, which is the percentile of X.The mean and the standard deviation are given, respectively, by:
[tex]\mu = 65\ \ \sigma= 3.5[/tex]
The proportion of women that cannot use the bikes(smaller than 54.5 inches) is the p-value of Z when X = 54.5, hence:
[tex]z=\dfrac{x-\mu}{\sigma}[/tex]
[tex]z = \dfrac{54.5-65}{3.5}[/tex]
Z = -3
Z = -3 has a p-value of 0.0013.
0.0013 = 0.13% of American women CAN NOT use the bicycles designed by this company.

Guys, can you please correct my answer for Question #45 of The Quadratic Relations for me, please?
Answer:
[tex]y=3(x-7)^2[/tex]
Step-by-step explanation:
Translations
For [tex]a > 0[/tex]
[tex]f(x-a) \implies f(x) \: \textsf{translated}\:a\:\textsf{units right}[/tex]
[tex]y=a\:f(x) \implies f(x) \: \textsf{stretched parallel to the y-axis (vertically) by a factor of}\:a[/tex]
Parent function
[tex]y=x^2[/tex]
Translated 7 units to the right
Subtract 7 from the x-value:
[tex]f(x-7) \implies y=(x-7)^2[/tex]
Vertically stretched by a factor of 3
Multiply the whole function by 3:
[tex]3f(x) \implies y=3(x-7)^2[/tex]
Streched 7 units right means change in x
So new equation
y=(x-7)²Vertically streched by 3
y=3(x-7)²Calculate.

Is this an example of inductive reasoning, deductive reasoning, or neither?
At the grocery store Mia saw a sign indicating that 3 grapefruit cost $2.50, so Mia bought 3 grapefruit.
A. Inductive
B. Deductive
C. Neither
Since the specific conclusion is based on a general premise, this is a case of deductive reasoning.
What is deductive reasoning?The term deductive reasoning has to do with the process of arriving at a specific conclusion based on a more general premise.
In this case, the conclusion arrived at was based on the fact that Mia saw a general sign that read that 3 grapefruit cost $2.50. Hence, this is a case of deductive reasoning.

How does the volume of the larger cube compare to the volume of the smaller cube? Use pencil and
paper. Use this and other examples to describe what happens to the volume of a cube if you triple the length
of the edges.
Answer:
Option C, The volume of the length cube is 3 times the volume of the smaller cube
Step-by-step explanation:
21.8 / 7.8 = 2.8
the volume of the larger would be 21.8^3 = 10360.23
the volume of the larger would be 7.8^3 = 474.55

Decide whether quadrilateral ABCD with vertices 4(3,1), B(-1,-1) C(1,3), and D(5,5) is a rectangle, rhombus,
square, or parallelogram.
Answer: rectangle
Step-by-step explanation:
From the options, it is implied that it is a parallelogram.
From inspection, we can tell that not all the sides are congruent, so it is not a rhombus or a square.
To determine if it is a rectangle, we can use the slope formula to see if there is a pair of perpendicular sides (if this is the case, then this will be a parallelogram with a right angle, making it a rectangle)
[tex]m_{\overline{AB}}=\frac{1-0}{-4-(-3)}=-1\\m_{\overline{BC}}=\frac{4-1}{-1-(-4)}=1\\\therefore \overline{AB} \perp \overline{BC} \text{ because} \left(m_\overline{AB} \right) \left(m_{\overline{BC} \right)=1[/tex]

Using the information in the diagram, what is the height of the tree to the nearest foot?
45 ft
54 ft
60 ft
135 ft
The relationship between the corresponding sides of similar triangles indicates that the height of the tree is 60 feet. The correct option is therefore;
60 ftWhat are similar triangles?Similar triangles are triangles in which the ratio of the corresponding sides of the triangles are equivalent for the three sides of the triangle.
The location of the tree divides the hypotenuse side and the base of the triangle formed by the building into two parts of the same length, therefore;
The length of the hypotenuse side to the building = 2 × 108 ft = 216 ft
The length of the base to the building = 2 × 90 ft = 180 ft
The ratio of corresponding sides of similar triangles and the trigonometric ratio of sines, indicates that we get;
Height of the tree/108 = 120/216
Height of the tree = 108 × (120/216) = 60 feet

V ... volume
B ... area of base
h ... height
The base of this pyramid is a square. Area of a square is side times side.

Solve |5x + 30| = 10x Identify the solution and an extraneous solution
Answer:
B
Step-by-step explanation:
the absolute value function always gives a positive result
However, the value inside can be positive or negative, that is
5x + 30 = 10x or - (5x + 30) = 10x
solving both
5x + 30 = 10x (subtract 5x from both sides )
30 = 5x ( divide both sides by 5 )
6 = x
or
- (5x + 30) = 10x
- 5x - 30 = 10x ( add 5x to both sides )
- 30 = 15x ( divide both sides by 15 )
- 2 = x
As a check
substitute these values into the equation and if both sides are equal then it is a solution.
x = 6
left side = | 5(6) + 30 | = | 30 + 30 | = | 60| = 60
right side = 10(6) = 60
Then x = 6 is a solution
x = - 2
left side = | 5(- 2) + 30 | = | - 10 + 30 | = | 20 | = 20
right side = 10(- 2) = - 20 ≠ 20
Thus x = - 2 is an extraneous solution
