132 people in the survey were in the 21 - 30 year old group
How to determine the number of people in the groupFrom the complete question, 22% of people are in the 21 - 30 year old group
Given that 600 people were surveyed.
The number of people in the 21 - 30 year old group would be:
n = 22% * 600
This gives
n = 132
Hence, 132 people in the survey were in the 21 - 30 year old group

8j + 5 = 61
Steps to solve
Answer:
j =7
Step-by-step explanation:
8j + 5 = 61
Subtract 5 from each side
8j + 5-5 = 61-5
8j = 56
Divide each side by 8
8j/8 = 56/8
j = 7
Answer:
J = 7
Step-by-step explanation:
8j + 5 = 61
8j = 61 - 5
8j = 56
8j ÷ 8 = 56 ÷ 8
j = 7

A jar contains n nickels and d dimes. There are 26 coins in the jar, and the total value of the coins is $1.90. How many nickels and how many dimes are in the jar?
Answer:
14 Dimes and 12 Nickels
Step-by-step explanation:
So you want to make 2 equations like this:
n+d=26
0.05n+0.10d=2
Now, use substitution and get d=26-n
plug that into the next equation and get
0.05n+0.10(26-n)=2
Distribute and combine like terms
0.05n+2.6-0.10n=2
2.6-0.05n=2
subtract 2.6 from both sides and you get
-0.05n=-0.6
Solve for n by dividing and you get
12 nickels.
Now, plug that into the first equation and you get
12+d=26
d=14

Chris is opening candy store. He is charging $4 for a small box of candy and then $1.25 for each additional box. What is the slope and y-intercept for this situation?
Answers:
Slope = 1.25
y intercept = 4
Explanation:
The slope is the rate of change. In this case, it's the price of getting an extra box.
The y intercept is the starting cost assuming that everyone has to get at least one small box of candy.
pls answer i have to get this done
Answer:
[tex]\huge\boxed{\times 2}[/tex]
Step-by-step explanation:
1 turned into 2, that means, it has been multiplied by 2.
1 × 2 = 2
3 turned into 6, that also means, it has been multiplied by 2.
3 × 2 = 6
So, both have been multiplied by 2.
[tex]\rule[225]{225}{2}[/tex]
Hope this helped!
~AH1807Answer: x 2
The answer is "x 2". This is because, as we see, 1 is then turned into 2. This is because 1 is multiplied by 2, which equals 2. 1 x 2 = 2. And 3 is turned into 6 through multiplication. 3 x 2 = 6. So we can see that the relationship between the quantities is "x 2".

Answer:
the first four terms are 2, 4, 6, and 8
Step-by-step explanation:
the y intercept becomes the first term. the for each value y increases by 2, this is the common difference.there are two ways you can get it. the by using equation of linear graphs y=mx+c and another by using the formula of AP Tn=a+(n-1)d.
both m(slope) and common difference(d) means the same thing.

Step-by-step explanation:
Noticing that 216 = 6^3 and using (x^a)^b = x^ab
216^2/3 = (6^3)^2/3 = 6^3 times 2/3 = 6^2 = 36

Answer:
x = 6
y = 5.5
Step-by-step explanation:
Since the shapes are similar:
A = E and
C = G
60+8x = 108 subtract 60 from both sides
8x = 48 divide both sides by 8
x = 6
8y - 3x = 62 we know x is 6
8y - 3*6 = 62
8y - 18 = 62 subtract 18 from both sides
8y = 44 divide both sides by 8
y = 5.5
In a bus of 40 passengers, the number of women is 7 times more than the number of men. How many women are on that bus? Explain your answer.
Answer: is 5
Step-by-step explanation:
x is the missing number for women women are 7 times more than the number of men
So you do x times 7, which is 7x
Then you add them together
x + 7x = 8x
8x = 40
At last you divide 40 by 8
And the answer is 5
If f(x) is an exponential function where f(1.5) = 7 and f(8.5) = 46, then find the value of f(14), to the nearest hundredth.
Answer:
[tex]f(14)=201.932[/tex]
Step-by-step explanation:
Set up a system of equations and solve for "b"
[tex]\left \{ {{46=ab^{8.5}} \atop {7=ab^{1.5}}} \right\\ \\\left \{ {{\frac{46}{b^{8.5}}=a } \atop {\frac{7}{b^{1.5}}=a} \right\\\\\frac{46}{b^{8.5}}=\frac{7}{b^{1.5}}\\ \\46b^{1.5}=7b^{8.5}\\\\46=7b^7\\\\\frac{46}{7}=b^7\\ \\b=1.308604899[/tex]
Determine the value of "a" using "b"
[tex]y=ab^x\\\\46=a(1.308604899)^{8.5}\\\\46=9.837224985a\\\\a=4.676115477[/tex]
Find f(14) using the new function
[tex]f(x)=4.676115477(1.308604899)^x\\\\f(14)=4.676115477(1.308604899)^{14}\\\\f(14)\approx201.932[/tex]

Error Analysis A math test asks the students to solve the inequality X-2511, and then graph the
solutions. Mason said the solutions are x s9 and graphed the solutions as shown below. Solve the
inequality and graph the solutions. What error might Mason have made?
What are the solutions?
X
Answer: x < 18
Step-by-step explanation:
x - 2 < 16
We eliminate 2 to isolate the variable, x by adding 2 to both sides. -2 + 2 = 0.
x < 18
We can test this because 17 is less than 18. Pretend x = 17
17 < 18✅
Mason subtracted 2, instead of adding 2.
In order to graph this, put an open circle at 18, and the arrow should point to the left.
Find all integers greater than 3 but less than 10

There's a positive correlation between the amount of fertilizer a homeowner uses
and the height of the plants in her garden.
Which statement is true?
The correlation is most likely a causation.
The correlation is most likely a coincidence.
The correlation is most likely due to a lurking variable.
Answer:
The correlation is most likely a causation
Step-by-step explanation:
Causation
A change in one variable causes a change in another variable
Coincidence
The two variables are not related at all, but correlate by chance.
Lurking variable
A variable that is not measured in the study (i.e. it's a third variable that is neither the explanatory nor the response variable)
As fertilizer directly affects plant growth, then the correlation is most likely a causation

An article reports that men over 6 feet tall earn more than men under 6 feet, with these numbers: average 6 foot plus male’s salary $55,000, average male’s salary under 6 foot tall of $47,000, with a p-value of 0.45. Based on that reported p-value, and using the common definition of "statistical significance," which is the case?
Answer:
D
Step-by-step explanation:
as the p value is 0.45 > 0.05 so the report that men over 6 feet tall earn more then men under 6 feet tall is accepted. So the salary differences are statistically signifcant
