Answer:
The population is 9,000 and the sample is 1,080
Step-by-step explanation:
Your population is 9,000 because that is how many people got the survey. The number 182,000 is irrelevant because that information does not matter with regards to the surveys. Your sample is 1080 because that is the number of people that responded.

Answer:
It is rigid
It is isometric
The size is preserved
Step-by-step explanation:
Given that Triangle ABC was translated to form A'B'C', then both triangles are congruent triangles.
A translation only moves the figure, preserving the size.
Because the size is preserved, it is a rigid transformation or isometric transformation.

The graphs below have the same shape. What is the equation of the blue graph? G(x) =
A. G(x)= (x+4)^2
B.G(x)=x^2+4
C.G(x)= (x-4)^2
D.G(x)= x^2-4
Answer:
CStep-by-step explanation:
G(x) is transformed from the parent function f(x)=x^2 by:
right 4 units
since we all know that the vertex form of a quadratic equation is y=a(x-h)^2+k
since 4 is h, and k is 0 ( graph is on the x-axis), we can write the equation of this graph:
g(x)=(x-4)^2, which is C
Decimal expansion of 5/8
Answer:

Step-by-step explanation:
1/8 = 0.125
0.125 times 55 = 0.625
What is the value for x?
Enter your answer in the box.
Answer:
8
Step-by-step explanation:
because we know its an isosceles triangle angle A and C will both be the same and since we know A = 69 C will also be 69. we also know that angles in a triangle add to 180 so take away the two 69s from the 180 to get 42
then we work backwards if its 5x + 2 then we need to do 5x - 2 to get 40 then divide it by 5 to get your answer 8!

Nate upgrades his phone. He makes 3 equal payments of $288 each and pays an additional $15 in taxes. What is x, the total cost of the phone?
Nate bought his 3 children identical phones and chargers. He spent a total of $288. If each charger was $15, what is x, the cost of one phone?
Nate bought his 3 children identical phones and chargers. He spent a total of $288. If each charger was $5, what is x, the cost of one phone?
Nate bought his 3 children identical phones totaling $288. Nate used a coupon for “$15 off total purchase.” What is x, the discounted price of one phone?
Answer:
the first and last option.
Step-by-step explanation:
the equation will be equal to 288.
x is the amount of one payment that he makes 3 times, hence the 3x.
15 is his initial payment so that is added to the 3x to equal 288.
the second equation still equals to 288.
the 15 is still there because added to the phone price it is equal to 288.
the x represents the price of the phones and 3 is how many he's getting, hence the 3x.

There are xboys playing in the park. The number of girls playing in the park is equal to the square root of the number of boys. If the total
number of boys and girls playing in the park is 42, find the number of boys.
A. 49
B.6
C. 36
D. 7
Answer:
x = 36 and √x = 6; total 42 children
Step-by-step explanation:
Number of boys: x
Number of girls: √x
Total number of kids: x + √x = 42.
Find x.
Rewrite x + √x = 42 as √x = 42 - x. Then square both sides:
x = 1764 - 84x + x^2, or
x^2 - 85x + 1764 = 0
Check out Answer C: x = 36. Is the above equation true for x = 36? YES
Check out Answer A: x = 49. Is the above equation true for x = 49? YES
Assume that x = 36. This would be the number of boys. The number of girls would be √36, or 6. Does the sum of 36 and 6 equal 42? YES. So the number of boys is 36 and the number of girls is 6.
Assume that x = 49. This would be the number of boys. The number of girls would be √49, or 8. Does the sum of 49 and 7 equal 42? NO. So we reject x = 49 as the number of boys and accept x = 36 as being correct.

An endangered whale species has a population of 6000. Biologists estimate that the stock is decreasing at 3% per year. At this rate, approximately how many years will it be before only 60% of the species remains?
A 9.0 years
B 9.6 years
© 10.0 years
D 16.8 years
9514 1404 393
Answer:
D. 16.8 years
Step-by-step explanation:
The multiplier each year is 1-3% = 0.97, so the multiplier after x years is 0.97^x. You want to know the value of x when that multiplier is 60%, or 0.60.
0.97^x = 0.60
x·log(0.97) = log(0.60) . . . . . . take logarithms
x = log(0.60)/log(0.97) ≈ 16.8
At the given rate, it will be 16.8 years before 60% of the species remains.

Sarah graphed the solution to the inequality StartAbsoluteValue f + 3 EndAbsoluteValue less-than 9 on the number line.
A number line going from negative 14 to positive 10. Open circles are at negative 12 and positive 6. Everything between the points is shaded.
Which inequality statement can be used to help determine if the graph is correct?
When f = 0, StartAbsoluteValue 0 + 3 EndAbsoluteValue less-than 9, which is true because 3 is less than 9.
When f = negative 12, StartAbsoluteValue negative 12 + 3 EndAbsoluteValue less-than 9, which is true because 9 is equal to 9.
When f = 10, StartAbsoluteValue 10 + 3 EndAbsoluteValue less-than 9, which is true because 9 is greater than 13.
When f = negative 14, StartAbsoluteValue negative 14 + 3 EndAbsoluteValue less-than 9, which is true because 9 is greater than –11.
Answer:
Correct option: first one.
Step-by-step explanation:
Let's analyse each option:
1)
When f = 0, |0 + 3| < 9, which is true because 3 is less than 9.
This statement is true, and the value f = 0 in inside the solution graphed by Sarah.
2)
When f = -12, |-12 + 3| < 9, which is true because 9 is equal to 9.
This statement is false, because the inequality uses a "less-than" symbol and not a "equal" symbol, so 9 < 9 is false
3)
When f = 10, |10 + 3| < 9, which is true because 9 is greater than 13.
This statement is false, because 9 is not greater than 13.
4)
When f = -14, |-14 + 3| < 9, which is true because 9 is greater than –11.
This statement is false, because the value of |-14 + 3| is 11 and not -11.
So the correct option is the first one.

Answer:
x = -6.
Step-by-step explanation:
5 -2x = -4x - 7
Add '4x' to both sides:
5 - 2x + 4x + -4x + 4x -7
5 + 2x = -7
Subtract '5' from both sides:
5 - 5 + 2x = -7 - 5
2x = -12
Divide both sides by '2':
x = -6.

OB.g(x) = 4(x+5)-6
O C.g(x) = 44.1
OD.g(x) = 4x + 5
Answer:
Step-by-step explanation:
For this case we have a function of the form:
f (x) = 4 ^ x-6
We want to move the graph five units up.
Therefore, the new function is given by:
g (x) = f (x) +5
Substituting we have:
g (x) = 4 ^ x-6 + 5
Rewriting the function:
g (x) = 4 ^ x-1

Option C is the correct answer.
What is a function?A function has an input and an output.
A function can be one-to-one or onto one.
It simply indicated the relationships between the input and the output.
Example:
f(x) = 2x + 1
f(1) = 2 + 1 = 3
f(2) = 2 x 2 + 1 = 4 + 1 = 5
The outputs of the functions are 3 and 5
The inputs of the function are 1 and 2.
We have,
To shift the graph of function f up 5 units, we need to add 5 to the output (y-value) of the function.
Therefore, the function g(x) will be:
g(x) = f(x) + 5
Substituting the expression for f(x), we get:
[tex]g(x) = 4^x - 6 + 5\\g(x) = 4^x - 1[/tex]
Therefore,
The function g which is created by shifting the graph of function f up 5 units is given by [tex]g(x) = 4^x - 1.[/tex]

Of 60 corn seeds that were planted, 18 of them did not sprout. What percent of the corn seeds
did not sprout? Show how you arrived at your answer.Of 60 corn seeds that were planted, 18 of them did not sprout. What percent of the corn seeds
did not sprout? Show how you arrived at your answer.
Answer:
30%
Step-by-step explanation:
18 / 60 = .3 * 100 = 30%
Answer:
The percent of the the corn seeds is 30%.
Step-by-step explanation:
Because when you calculate 60% and 18% will get a percent 30%.
Solution for 18 is what percent of 60:
18:60*100 =
( 18*100):60 =
1800:60 = 30
Now we have: 18 is what percent of 60 = 30
Question: 18 is what percent of 60?
Percentage solution with steps:
Step 1: We make the assumption that 60 is 100% since it is our output value.
Step 2: We next represent the value we seek with $x$.
Step 3: From step 1, it follows that $100\%=60$.
Step 4: In the same vein, $x\%=18$.
Step 5: This gives us a pair of simple equations:
$100\%=60(1)$.
$x\%=18(2)$.
Step 6: By simply dividing equation 1 by equation 2 and taking note of the fact that both the LHS
(left hand side) of both equations have the same unit (%); we have
$\frac{100\%}{x\%}=\frac{60}{18}$
Step 7: Taking the inverse (or reciprocal) of both sides yields
$\frac{x\%}{100\%}=\frac{18}{60}$
$\Rightarrow x=30\%$
Therefore, $18$ is $30\%$ of $60$.
