Which expression represents
(25– 12)!12!?
25012
o 23C13
25P 12
Answer:
[tex]25C_{12}[/tex]
Step-by-step explanation:
We are given that an expression
[tex]\frac{25!}{(25-12)!12!}[/tex]
We have to find the expression which represents [tex]\frac{25!}{(25-12)!12!}[/tex].
We know that
[tex]nP_r=\frac{n!}{(n-r)!}[/tex]
[tex]nC_r=\frac{n!}{(n-r)!r!}[/tex]
By using the formula
By comparing we get
n=25,r=12
[tex]\frac{25!}{(25-12)!12!}[/tex]
[tex]=25C_{12}[/tex]
Hence, option a is true.

Answer:
8units²
Step-by-step explanation:
Area of the trapezoid = 1/2(a+b)h
a and b are the opposite sides
h is the height
Take a square as 1 unit
a = 1 unit
b = 3 units
height h = 4 units
Substitute
A = 1/2(1+3)*4
A = 1/2 * 4 * 4
A = 16/2
A = 8units²
Hence the area of the trapezoid is 8units²
2x+6y=21 and -2x+3y=24 using the elimination method and write as an ordered pair
Answer:
(-0.5,7.66)
Step-by-step explanation:
2x+6y=21
-2x+3y=24
so 3y=24+2x
reduce
y=(24+2x)/3
substitute for y
2x+6(24+2x/3)=21
2x+(72+12x)/3=21
2x+24+4x=21
6x=-3
x=-0.5
y=(24+-1)/3=7.66
2m+(m-15)=90 solve for m
Answer:
m = 35
Step-by-step explanation:
2m + m -15 = 90
3m -15 = 90
+15 +15
3m = 105
/3 /3
m = 35
To check the work just insert 35 for m:
2(35) + 35 -15 = 90
70 + 35 -15 = 90
105 - 15 = 90
90 = 90

Make a table showing all the possible outcomes for spinning the pointer of a spinner with four equal-sized sections labeled 1–4 and another spinner with four equal-sized sections labeled A–D. Use this table to determine the probability that the two pointers will land on an odd number and the letter C. Give the probability as a percent, rounded to the nearest tenth of a percent.
P(odd number, C) =
%
Answer:
12.5%
Step-by-step explanation:
There are two types of spinners here and the outcome of them is independent. That means
P(odd number,C) = P(odd number) * P(C)
There are two odd numbers out of four numbers in the first spinner. The chance of odd number will be:
P(odd) = 2/(2+2)= 1/2= 50%
There are four letters and the desired outcome is C. The chance for C will be:
P(C)= 1/4= 25%
Then the chance will be:
P(odd number,C) = P(odd number) * P(C)
P(odd number,C) =50% * 25% = 12.5%
