How many ways can 7 basketball players be listed in order in a program? A. 5,040 B. 720 C. 120 D. 1
Answers
Answer:
A. 5040
Step-by-step explanation:
Number of players of the basketball = 7 and these players are to be listed in order in a program.
Since in any question if order is important then permutation is used and if order does not matters combination is applied.
Therefore for this question where 7 basketball players are to be listed in order, means order matters so permutation is to be used.
Therefore option A 5040 is the right answer.
Since the order of basketball players is important, permutation is used. The problem could be interpreted as the permutation of 7 taken 7 at a time
nPr = n! /(n-r)! = 7! /0! = 5040 ways.
The answer is A.

Answer:
a = 3
Step-by-step explanation:
f(x) = a(bˣ)
At x = 0
f(0) = a(b⁰)
f(0) = a(1)
f(0) = a
From the graph
f(0) = 3
Therefor
a = 3

Angles in a triangle may or may not be congruent.
The values of x and y are 90 and 47, respectively.
From the figure, we have:
This means that, angle x is a right-angle.
So, we have:
Triangle ABC is an isosceles triangle.
So, we have:
The measure of y is then calculated as:
--- sum of angles in a triangle
This gives
Subtract 137 from both sides
Hence, the values of x and y are 90 and 47, respectively.

Recall the properties of Isosceles Triangle:
An isosceles triangle has equal base angles an two equal legs that are opposite the base angles.
Triangle ABC is an isosceles triangle.
- Therefore:
m<ACD = m<ABD = 47 degrees
Find y:
- Substitute
y = 1/2(180 - (47 + 47))
y = 43 degrees.
Find x:
x = 180 - (y + m<ABD)
- Substitute
x = 180 - (43 + 47) (sum of triangle)
x = 90 degrees
Therefore, applying the properties of Isosceles triangle and the sum of triangle theorem, the values of x and y in the image given are:

Let's start by breaking down the problem so that it's not overwhelming.
For now, we're only going to focus on the very beginning of the problem -- 4c.
When a number is next to a letter with no signs in between (in terms of this kind of math), the number is called a coefficient and the letter is called a variable. When you see this in math, it means that the coefficient is being multiplied by the variable. But how do you know what the variable is?
In other examples of math, you'd have to solve for the variable, but in this case, they already give it to you! Look back at the top... what does C equal? It equals 4! This means that 4c is actually 4x4, or 4(4)!
What we just did there, changing 4c to 4 multiplied by 4, is called substitution. You just substituted the c with 4. Now you know that to solve this, you need to use the method of substitution. What do you get if you substitute all of the variables with the numbers they equal (as shown above)...?
((4*-4)*5)((10(2*2))/(50(5)))+20(-1). You didn't use parentheses to separate the term /50d + 20q, so I'm assuming that the first part of the problem is only divided by just 50d, and not 50d+20q. In the future, be sure to clarify with parentheses. Anyway...
((4*-4)*5)((10(2*2))/(50(5)))+20(-1). Do NOT let this scare you. All the parentheses do is help you see what is being multiplied. All that's left is simple order of operations! You should get -340 as your answer.
