In 1912, the U.S. government began issuing licenses to radio stations. Each station was given a unique three-letter call sign. Radio stations in the western United States were given call signs starting with K. Stations in the east were given call signs starting with W. For example, the radio station with the call sign ABC is KABC in California, and WABC in Georgia.
a. How many different three-letter call signs are there?
Hint: don’t worry about the K or W – just find the number of ways to arrange any 3 letters
b. How many different three-letter call signs are there where the first letter is a D?
Hint: again, the K and W don’t matter
c. In a random selection of radio station call signs, what is the probability of selecting a radio station with a call sign that starts with the letter D?
Answer:
A would make sense

Write an equation of the line that passes through (-1,4) and is perpendicular to the line shown.
Yeah my math class is coocoo, and im stuck on this. Im slow. Help me :(
Answer:
y=4x+4
Step-by-step explanation:
i was learning this not too long ago so i hope this helps y=mx+b aka slope is 4 and then for b you put the y intercept aka 4 and then the x and y factors you csn leave blank cause you dont have them
An equation of the line that passes through (-1,4) and is perpendicular to the line given in the graph is y=3x+7.
The coordinates from the line on the graph is (-3, 4) and (3, 2).
What is slope of a line?The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.
The formula to find the slope of a line is slope = (y2-y1)/(x2-x1)
Now, slope =(2-4)/(3+3)
= -2/6
= -1/3
Substitute m=-1/3 and (x, y)=(-3, 4) in y=mx+c, we get
4=-1/3 (-3)+c
⇒ c=3
The slope of a line perpendicular to given line is m1=-1/m2
So, slope =3
An equation of the line that passes through (-1,4)
Now, 4=3(-1)+c
c=7
Put m=3 and c=7 in y=mx+c, we get
y=3x+7
Therefore, an equation of the line that passes through (-1,4) and is perpendicular to the line given in the graph is y=3x+7.

Please help I really need it!! A student found out that 8% of the students in his school are left-handed.If there are 114 lefties, how many students are in his school?
Answer:
x = 1425
Step-by-step explanation:
Given that,
A student found out that 8% of the students in his school are left-handed.
Total no of lefties = 114
We need to find the total number of students in the school. Let they are be x.
ATQ,
8% of x = 114
[tex]\dfrac{8x}{100}=114\\\\x=\dfrac{114\times 100}{8}\\\\=1425[/tex]

What is the vertex for the graph shown below?
a. (0,0)
b. v=1
c. v=5
d. (5,1)
Answer:
D. (5,1)
Step-by-step explanation:
The vertex of the graph is V ( 5 , 1 ).
Given data:
The vertex of a function is a point on the graph where the function reaches its highest or lowest point, depending on whether the function is concave up or concave down.
The vertex represents the minimum or maximum point of the function and provides information about the axis of symmetry of the graph. If the function opens upward (concave up), the vertex is the lowest point (minimum).
So, the highest point in the graph where the function reaches the minimum value is when x = 5
So, the value of y = 1
Hence , the vertex is V ( 5 , 1 ).

Determine whether or not the equation shows a proportional relationship. If it does, identify the unit rate (constant of proportionality).
y =25x, a = 5x + 5, m = 105.25n
Answer:
y = 25·x shows a proportional relationship
a = 5·x + 5 does not show a proportional relationship
m = 105.25·n shows a proportional relationship
Step-by-step explanation:
An equation that shows a proportional relationship is of the form, y = kx
Where;
k = The constant of proportionality = y/x
Therefore, the equation, y = 25·x shows a proportional relationship
The constant of proportionality = k = y/x = 25
Similarly, the equation m = 105.25·n shows a proportional relationship
The constant of proportionality = k = m/n = 105.25
When the equation shows a proportional relationship, the graph of the equation passes through the origin, therefore, the equation of the form, y = m·x + c, where c = the y-intercept > 0, the equation does not show a proportional relationship
The equation a = 5·x + 5, which is of the form, y = m·x + c, with c = 5 > 0, therefore, does not show a proportional relationship.
Therefore;
y = 25·x shows a proportional relationship
m = 105.25·n shows a proportional relationship
a = 5·x + 5 does not show a proportional relationship.
Eric conducted a survey of the cars in four parking lots and wrote the following observations:
15 of the 36 cars in lot 1 were blue
43 of the 92 cars in lot 2 were blue
12 of the 30 cars in lot 3 were blue
32 of the 52 cars in lot 4 were blue
Based on the survey, which parking lot had the greatest percentage of blue cars?
explain your answer
Answer:
Lot 4 since 61.5% is the highest percentage of blue cars of all lots.
Step-by-step explanation:
Find the percentage that each number of blue cars is in its parking lot.
percent = part/whole * 100%
15 of the 36 cars in lot 1 were blue
15/36 * 100% = 41.667%
43 of the 92 cars in lot 2 were blue
43/92 * 100% = 46.739%
12 of the 30 cars in lot 3 were blue
12/30 * 100% = 40%
32 of the 52 cars in lot 4 were blue
32/52 * 100% = 61.538%
Answer: Lot 4 since 61.5% is the highest percentage of blue cars of all lots.
Answer:
Parking Lot 4
Step-by-step explanation:
15÷36 x 100 = 41.666%
43÷ 92 x 100 = 46.739%
12 ÷ 30 x 100 = 40%
32÷ 52 x 100 = 61%
61% is the largest percentage out of all of them, therefore Parking Lot 4 ( 32 out the 52 cars) is the Parking Lot that has the greatest percentage of blue cars!

There is 1/2 of a greater chance in drawing a spade over drawing a 7
How to determine the probability?From the complete question added as an attachment, we have the following parameters:
n(Spade) = 4n(7) = 1Total = 6The probability of getting a spade is:
P(Spade) = 4/6
The probability of getting a 7 is:
P(7) = 1/6
The difference between both probabilities is:
Difference = 4/6 - 1/6
Evaluate
Difference = 3/6
Simplify
Difference = 1/2
Hence, there is 1/2 of a greater chance in drawing a spade over drawing a 7
