Given:
The expression are
(i) [tex]5x-3[/tex]
(ii) [tex]11-2y^2[/tex]
(iii) [tex]2x-1[/tex]
To find:
The terms which are not constants and their numerical coefficients.
Solution:
Constants: The terms which are free from variables.
Numerical coefficient: Number multiplied with a variable.
(i) [tex]5x-3[/tex]
Constant = -3
Term which is not constant = 5x
Numerical coefficient = 5
(ii) [tex]11-2y^2[/tex]
Constant = 11
Term which is not constant = [tex]-2y^2[/tex]
Numerical coefficient = -2
(iii) [tex]2x-1[/tex]
Constant = -1
Term which is not constant = 2x
Numerical coefficient = 2
Therefore, the terms which are not constants are [tex]5x,-2y^2,2x[/tex] respectively and their numerical coefficients are 5, -2, 2 respectively.

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:
31%
Step-by-step explanation:
93/300=0.31
0.31=31%
The percentage of the surveyed students said their favorite color was purple will be 31%.
What is mean by Percentage?
A number or ratio that can be expressed as a fraction of 100 or a relative value indicating hundredth part of any quantity is called percentage.
To Calculate the percent of a number , divide the number by whole number and multiply by 100.
Given that;
Total number of students = 300
And, There are 93 students said their favorite color was purple.
Now,
The percentage of the surveyed students said their favorite color was purple is find as;
Total number of students = 300
And, There are 93 students said their favorite color was purple.
So, Percent of the surveyed students said their favorite color was purple is;
Percent = 93 / 300 x 100
= 31%
Thus, The percentage of the surveyed students said their favorite color was purple will be 31%.

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

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%

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

) A computer program found that the line LaTeX: c=2t-89c = 2 t − 89 is a good fit for the data. Use this equation to predict how many cups of lemonade Lin might sell on a day when the high temperature is 74 degrees. We predict she will sell 40 cups of lemonade.
Answer:
Number of cups of lemonade = 59 cups
Step-by-step explanation:
Given the linear function :
C = 2t - 89
At temperature of 74° ;
The cups of lemonade as calculated using the linear model:
C = 2t - 89 ; where c = cost of lemonade ; t = temperature.
C = 2(74) - 89
C = 148 - 89
C = 59
A function assigns the values. The prediction that she will sell 40 cups of lemonade that day is wrong.
What is a Function?A function assigns the value of each element of one set to the other specific element of another set.
As it is given that function, c=2t-89, where the number of cups of lemonade is represented by c, and t represents the temperature of the day.
Now, as it is given that the temperature at the day is 74, therefore, the number of cups that will be sold that day can be predicted as,
[tex]c = 2t-89\\\\c = 2(74)-89\\\\c = 148-89\\\\c = 59[/tex]
Hence, the prediction that she will sell 40 cups of lemonade that day is wrong.
