Answer:
3c + 14d
Step-by-step explanation:
Hello There!
We can simplify this expression by combining like terms
Now what are like terms?
They are terms that have the same variable ex. 4a and 2a are like terms as they have the same variable (a)
Now lets look back at the expression and see if there are any like terms
which there are (4c and -c) and (6d and 8d)
so lets combine them
4c - c =3c
6d + 8d = 14d
so the simplified version would be 3c + 14d
Answer:
B) 3c+14d
Step-by-step explanation:
We use the addition property for the following question
First we rearrange the following problem and we get
4c-c+6d+8d
The easiest way is to just add and subtract or if you want have a better understanding, you can factor our the like terms which gives us
(4-1)c+(6+8)d
and then we can simplify to get
3c+14d

In a large population, 92% of the households have cable tv. A simple random sample of 225 households is to be contacted and the sample proportion computed. What is the mean and standard deviation of the sampling distribution of the sample proportions
Answers
Answer:
the mean and the standard deviation is 0.92 and 0.01808 respectively
Step-by-step explanation:
The computation of the mean and the standard deviation is shown below:
The mean is 0.92
And, the standard deviation is
= √0.92 × (1 - 0.92) ÷ √225
= √0.92 × 0.08 ÷ √225
= √0.0736 ÷ √225
= √3.27
= 0.01808
Hence, the mean and the standard deviation is 0.92 and 0.01808 respectively

Complete question :
From Monday through Friday, James works in the library on 2 days and in the cafeteria on another day. On Saturday and Sunday, James washes cars 50% of the days. How many days does James work in a week? What percent of the days from Monday through Friday does he work?
Answer:
4 days ;
60%
Step-by-step explanation:
From Monday to Friday
Number of days in library = 2
Number of days in cafeteria = 1
50% of days in weekends
Number of weekend days = 2
50% of 2 = 0.5 * 2 = 1 day
Total. Number of days worked = (2 +1 + 1) = 4 days
What percent of the days from Monday through Friday does he work?
Number of days workwd from. Monday to Friday = 3
Total number of days from Monday to Friday = 5
Percentage of days worked from Monday to Friday
= number of days worked / total number of days
= 3 /5 * 100%
= 0.6 * 100%
= 60%

Answers
(This should be typed into a calculator - it’s the equation)
Remember the differences between sine, cosine, and tangent
If you set up the equation of:
sin theta = opposite / hypotenuse
You get sin38° = x / 12.7
You are trying to find x so multiply both sides by 12.7
* x is the opposite side because it is across from the angle given
A triangle has sides with lengths of 26 yards, 76 yards, and 78 yards. Is it a right triangle?
Options:
Yes
No
Answers
Answer:
No
Step-by-step explanation:
a^2 + b^2 = c^2
Since 78 is the largest it will be c.
26^2 + 76^2 = 78^2
676 + 5776 = 6084
6452 does NOT = 6084
Since c^2 is larger it is an obtuse triangle.

Voting in Seaside's annual school board elections has been going down by 10% from one election to the next. If 990 parents voted this year, how many will vote 4 years from now?
If necessary, round your answer to the nearest whole number.
Answers
Answer:
FV= 676
Step-by-step explanation:
Giving the following formula:
Present value (PV)= 990 parents
Decrease rate (d)= 10% = 0.1 per year
Number of periods (n)= 4
To calculate the future value of votes, we need to use the following formula:
FV= PV / (1 + d)^n
FV= 990 / (1.1^4)
FV= 676

What value of x makes this proportion true? x/6=36/24 O A. 8 O B. 9 O C. 18 O D. 7
Answers
Answer:
B. 9
Step-by-step explanation:
Proportions are just like fractions and to figure them out sometimes you can use simplification in different forms.
[tex]\frac{x}{6}[/tex] = [tex]\frac{36}{24}[/tex]
Now to get to 6, 24 had to be divided by 4...in proportions and fractions usually, the top and bottom are both simplified or proportioned to the same number or scale
36 ÷ 4 = 9
Check your answer by inserting it there to see if it works
9*4 = 36 6*4 = 24
Answer:
[tex]\boxed {\boxed {\sf B. \ 9}}[/tex]
Step-by-step explanation:
We are given this proportion:
[tex]\frac {x}{6}=\frac{36}{24}[/tex]
We want to solve for x, so we must isolate the variable using inverse operations.
It is being divided by 6. The inverse of division is multiplication, so we multiply both sides of the proportion by 6.
[tex]6*\frac {x}{6}=\frac{36}{24}*6[/tex]
[tex]x=\frac{36}{24}*6[/tex]
[tex]x=1.5*6 \\x=9[/tex]
Another way to solve is with cross multiplication. Multiply the first numerator by the second denominator, then the first denominator by the second numerator.
[tex]\frac { x}{6}=\frac{36}{24}[/tex]
[tex]24*x=6*36[/tex]
[tex]24x=216[/tex]
The variable is being multiplied by 24. The inverse of multiplication is division, so we divide both sides of the equation by 24.
[tex]24x/24=216/24\\x=9[/tex]
The value of x that makes this proportion true is 9.
