Answer: 6
Step-by-step explanation: Since there are three different ways to get from A to B, that creates three variants of each way to get from B to C.
Say the roads are numbered. From A to B, you can use roads 1, 2, or 3. From B to C, you can use roads 4 or 5. The different combinations are 1-4, 1-5, 2-4, 2-5, 3-4, and 3-5.

Jody decides to ride her bike from her house to the park. The distance she travels on her bike, in kilometers, is equal to the function f(t), where t represents the number of hours she has been riding her bike. Jody rides her bike from her house to the park. Before Jody leaves her house f(0) = 0, and when Jody reaches the park f(2) = 30. From the information given, determine whether each statement is a correct interpretation that can be made about Jody's bike ride. Select Correct or Incorrect for each statement. Correct Incorrect It takes Jody 2 hours to bike to the park. The park is located 2 kilometers from Jody's house. When Jody is at her house she has biked for 0 hours.
Answer:
A)It takes Jody 2 hours to bike to the park.- Correct
B)The park is located 2 kilometers from Jody's house.- Incorrect
C) When Jody is at her house she has biked for 0 hours.- Correct
Step-by-step explanation:
We are given that The distance she travels on her bike, in kilometers, is equal to the function f(t), where t represents the number of hours she has been riding her bike.
f(t)= Distance covered in t hours
t = time in hours
Jody rides her bike from her house to the park. Before Jody leaves her house f(0) = 0
So, Distance covered in 0 hours is 0 km
So, When Jody is at her house she has biked for 0 hours
Jody reaches the park f(2) = 30.
So, Distance traveled in 2 hours is 30 km
So, It takes 2 hours to reach park
A)It takes Jody 2 hours to bike to the park.- Correct
B)The park is located 2 kilometers from Jody's house.- Incorrect
C) When Jody is at her house she has biked for 0 hours.- Correct

Bethany uses the equation d=3.75h to find the distance, d, she travels while walking for h number of hours. what is the constant of proportionality between d and h? show your work
Answer:
The constant of proportionality between d and h is 3.75
Step-by-step explanation:
The direct proportionality function is called any function in which the dependent variable (y) is obtained by multiplying the independent (x) by a constant value. This type of function is more commonly called a linear function and has an expression of the form:
y=m*x
The value m is a constant called the constant of proportionality or the slope of the line and represents the inclination of the line with respect to the abscissa axis, that is, the x axis. Graphically this linear function is a line with slope m that passes through the origin of coordinates, that is, the point 0 in x and 0 in y, which is the point (0,0).
You know that Bethany uses the equation d=3.75*h to find the distance, d, she travels while walking for h number of hours. Comparing with the direct proportionality function y = m * x, then y is represented by the distance d, x is represented by the number of hours h and the constant of proportionality or slope m is the number 3.75.
So, the constant of proportionality between d and h is 3.75

The Stanford-Binet Intelligence Scale is an intelligence test, which, like many other IQ tests, is standardized in order to have a normal distribution with a mean of 100 and a standard deviation of 15 points.
As an early intervention effort, a school psychologist wants to estimate the average score on the Stanford-Binet Intelligence Scale for all students with a specific type of learning disorder using a simple random sample of 36 students with the disorder.
Determine the margin of error,
, of a 90% confidence interval for the mean IQ score of all students with the disorder. Assume that the standard deviation IQ score among the population of all students with the disorder is the same as the standard deviation of IQ score for the general population, =15
points.
Give your answer precise to at least two decimal places.
Answer:
4.11
Step-by-step explanation:
Margin of error equals critical value times standard error.
MoE = CV × SE
For 90% confidence and n > 30, the critical value is z = 1.645.
The standard error is SE = σ/√n = 15/√36 = 2.5.
Therefore, the margin of error is:
MoE = (1.645) (2.5)
MoE = 4.11
The margin of error of a 90% confidence interval for the mean IQ score of all students with the disorder is 4.1125 and this can be determined by using the formula of margin of error.
Given :
Standardized in order to have a normal distribution with a mean of 100 and a standard deviation of 15 points.A school psychologist wants to estimate the average score on the Stanford-Binet Intelligence Scale for all students with a specific type of learning disorder using a simple random sample of 36 students with the disorder.90% confidence interval.According to the given data, the confidence is 90% and n > 30, so the critical value is z = 1.645.
Now, to determine the standard error using the below formula:
[tex]\rm SE = \dfrac{\sigma}{\sqrt{n} }[/tex]
[tex]\rm SE = \dfrac{15}{\sqrt{36} }=\dfrac{15}{6}[/tex]
SE = 2.5
Now, the formula of margin of error is given by:
[tex]\rm MOE = z\times SE[/tex]
MOE = (1.645) [tex]\times[/tex] (2.5)
MOE = 4.1125
So, the margin of error is 4.1125.

Titus took 30 minutes to walk 2 miles at a constant rate. Let d represent the distance Titus walks in miles after t minutes. What are two different constants of proportionality for the relationship between distance, in miles, and time, in minutes?
Answer:
15 and 1/15
Step-by-step explanation:
Given
Time (t) = 30 minutes
distance (d) = 2 miles
To determine the first constant of proportionality
Let time be directly proportional to distance.
t = kd
Where k is the constant of proportionality
Make k the subject
k = t/d
Substitute values for t and d
k = 30/2
k = 15
To determine the second,
Let distance be directly proportional to time.
d = kt
Make k the subject
k = d/t
Substitute values for d and t
k = 2/30
k = 1/15
Hence, the constant of proportionality are
15 and 1/15

In triangle QRS the measure of right angle S is SQ=90 degrees Sq=47 feet and Rs=70 feet. Find the measure of angle R to the nearest tenth of a degree
Answer:
x=33.9°
Step-by-step explanation:
Trigonometric Ratios
In a right triangle, i.e. the triangles that have an internal angle of 90°, the so-called trigonometric ratios are valid.
There are six trigonometric ratios that can be used in right triangles, depending on the data available for each problem.
The current question gives us two sides in a right triangle and requires us to calculate the angle x.
The angle x 'looks' at the sides of the triangle in this way: RS=70 is the adjacent leg, SQ=47 is the opposite leg, and RQ is the hypotenuse.
We should use the trigonometric ratio that relates both the adjacent and the opposite led. There are two possibilities: The tangent and the cotangent. We'll use the tangent for no particular reason.
The tangent of an angle is defined as:
[tex]\displaystyle \tan\x=\frac{\text{opposite leg}}{\text{adjacent leg}}\\[/tex]
Use the given values:
[tex]\displaystyle \tan x=\frac{47}{70}=0.6714[/tex]
Using a calculator (in degree mode), we calculate the angle:
[tex]x=\tan^{-1}(0.6714)=33.9^\circ[/tex]
x=33.9°
