Answer:
[tex]\boxed {\tt 23}[/tex]
Step-by-step explanation:
In order to find the mean, we must add all the values together, then divide by the number of values.
1. Add the values together
The values are: 5, 15, 25, 25, 45 Add the together: 5+ 15 + 25 + 25 +45=1152. Divide by the number of values.
Count how many values are in the set of data. There are 5 values. Divide by 5.
Divide: 115/5 =23The mean is 23.
Bill placed a coordinate grid over a drawing of his back yard. Points A (-2, -3) and B (4, 9) represent two corners of his garden. He wants to place a water sprinkler (C) at the midpoint between A and B.
Answer:
(1;3)
Step-by-step explanation:
midpoint=(x1+x2;y1+y2)÷2
=(-2+4;-3+9)÷2
=(2;6)÷2
=(1;3)
Brad and Stella volunteer to help at the party. Brad volunteers at the prize table and Stella
volunteers at the refreshment table. Both workstations allow volunteers a short break, but at
different intervals. The prize table allows volunteers a short break every 20 minutes, but the
refreshment table allows a short break only every 30 minutes. If the party is scheduled to start
at 2:00 pm and Brad and Stella both start working then, what is the first time that they will be
on break together? Show all work.
Answer:
They will be able to have their break together in 60 minutes.
Step-by-step explanation:
You will have to find the least common multiple (LCM) between 20 and 30.
The prime factorization of 20 is: 2 x 2 x 5
The prime factorization of 30 is: 2 x 3 x 5
Eliminate the duplicate factors of the two lists, then multiply them once with the remaining factors of the lists to get lcm(20,20) = 60
In a box there are 3 red pens, 2 green pens, and 1 blue pen. What is the probability of picking a red pen, not replacing it, and then picking a blue pen
Answer:
1/10
Step-by-step explanation:
First, find the probability of choosing the red pen:
There are 6 total pens and 3 are red, so the probability will be 3/6
This can be simplified to 1/2
Then, find the probability of choosing a blue pen after not replacing the red one:
There are 5 total pens now, since we did not replace the red one.
There is only 1 blue pen, so the probability is 1/5
Then, multiply these 2 probabilities together:
1/2(1/5)
= 1/10
So, the probability is 1/10

Are 12/16 and 6/9 equivalent? Explain your answer.
Answer:
No
Step-by-step explanation:
Times the numerator and denominator by 2. 6 does turn into 12, but 9 doesn't turn into 16. Therefore, these fractions are not equivalent.
The sales tax rate in Virginia is 4.5%. This is 2.5% less than the sales tax rate in Rhode Island. What is Rhode Island’s sales tax rate?
Answer:
7.0%
Step-by-step explanation:
If the sales tax in Virginia is 2.5% less than Rhode Island, then the tax rate in Rhode Island is 2.5% MORE than Virginia, so we add it to Virginia’s tax rate.
4.5% + 2.5% = 7.0%
48 = 4x – 2 + 6x
Need help ASAP
Answer:
x= 5
Step-by-step explanation:
48 = 4x – 2 + 6x
Combine like terms
48 = 10x-2
Add 2 to each side
48+2 = 10x-2+2
50 = 10x
Divide by 10
50/10 = 10x/10
5 =x
Answer:
[tex] \boxed{ \bold{ \huge{ \boxed{ \sf{x = 5}}}}}[/tex]
Step-by-step explanation:
[tex] \sf{48 = 4x - 2 + 6x}[/tex]
Collect like terms
[tex] \longrightarrow{ \sf{48 = 10x - 2}}[/tex]
Swap the sides of the equation
[tex] \longrightarrow{ \sf{10x - 2 = 48}}[/tex]
Move 2 to right hand side and change it's sign
[tex] \longrightarrow{ \sf{10x = 48 + 2}}[/tex]
Add the numbers: 48 and 2
[tex] \longrightarrow {\sf{10x = 50 }}[/tex]
Divide both sides by 10
[tex] \longrightarrow{ \sf{ \frac{10x}{10} = \frac{50}{10}}} [/tex]
Calculate

HELP DUE LIKE RIGHT NOW
Answer:
The correct answer is x = 17.
Step-by-step explanation:
If EF bisects DEG, this means that angles DEF and angles FEG are congruent, and they each make up half of angle DEG.
Therefore, we can set up the equation:
DEF + FEG = DEG
However, since we know that DEF and FEG represent the same value, we can change this equation into the following:
2(DEF) = DEG
Now, we can substitute in the expressions that we are given:
2(3x+1) = 5x + 19
To simplify, we should first use the distributive property on the left side of the equation.
6x + 2 = 5x + 19
Our next step is to subtract 5x from both sides of the equation.
x + 2 = 19
Finally, we can subtract 2 from both sides of the equation to get x by itself on the left side.
x = 17
Therefore, the value of x is 17.
Hope this helps!

Answer:
[tex]x=3/2=1.5[/tex]
Step-by-step explanation:
So we have the equation:
[tex]49=7^{2x-1}[/tex]
Note that 49 is the same as 7 squared. Thus:
[tex](7)^2=(7)^{2x-1}[/tex]
Since they now have the same base, the exponents must be equal to each other. So:
[tex]2=2x-1[/tex]
Add 1 to both sides:
[tex]3=2x[/tex]
Divide both sides by 2:
[tex]x=3/2=1.5[/tex]

Let f(x) = 16 - x^2, g(x) = 4 - x. Find (fg)(x) and its domain.
Answer:
(fg)(x) = x^3-4x^2-16x+64, D: All Real Numbers
Step-by-step explanation:
(fg)(x) = f(x) x g(x)
= 16-x^2(4-x)
=64-16x-4x+x^3
(fg)(x) = x^3-4x^2-16x+64
Domain is all real numbers because you can substitute any real number for x and the function would still work.
Thus the value of [tex](fg)(x) = x^3 -4x^2 -16x -64[/tex] , and the domain is a set of real numbers.
The domain is a set of all real numbers because by substituting any value in the equation we only get real numbers.
The function is defined as a relationship between two variables a dependent and an independent variable. A function consists of a domain and a co-domain. The set of codomains is called a range.
Example : [tex]f(x) = 4x+ 3[/tex]
All those values of a set for which a function is defined are called a domain.
According to the question :
[tex]f(x) = 16 - x^2\\ g(x) = 4 - x.[/tex]
[tex](fg)(x) = (16- x^2) (4-x)\\(fg)(x) = [16(4-x) -x^2(4- x)]\\\(fg)(x) = [64- 16x -4x^2+x^3]\\(fg)(x) = x^3 -4x^2 -16 x -64[/tex]
Thus the value of [tex](fg)(x) = x^3 -4x^2-16x-64.[/tex]

What value of n makes the equation?
8n - 5 = -2n + 5 true?
Answer:
[tex]n=1[/tex]
Step-by-step explanation:
[tex]8n - 5 = -2n + 5[/tex]
First, add 5 to both sides.
[tex]8n-5+5=-2n+5+5\\[/tex]
[tex]8n=-2n+10[/tex]
Then, add 2n to both sides.
[tex]8n+2n=-2n+10+2n[/tex]
[tex]10n=10[/tex]
Finally, divide both sides by 10.
[tex]\frac{10n}{10}=\frac{10}{10}[/tex]
[tex]n=1[/tex].
Answer:
[tex]n=1[/tex]
Step-by-step explanation:
So we have the equation:
[tex]8n-5=-2n+5[/tex]
First, add 2n to both sides. The right side cancels:
[tex]10n-5=5[/tex]
Add 5 to both sides:
[tex]10n=10[/tex]
Now, divide both sides by 7:
[tex]n=1[/tex]
