Answer:
x = 1,650
Step-by-step explanation:
A real-world problem with a sample and a population is modeled by the proportion 66/100=x/2,500. Use the proportion to complete the sentences.
From the above question, we have to solve for x
Hence, we have the proportion
66/100=x/2,500
Cross Multiply
100 × x = 66 × 2,500
x = 66 × 2,500/100
x = 1,650

3(2x-4)=3X-3. What is the x?
Answer:
x = 3
Step-by-step explanation:
Distributive property: a(b + c) = (a*b) + (a*c)
3(2x - 4) = 3x - 3
3*2x - 3*4 = 3x - 3
6x - 12 = 3x - 3 {Add 12 to both sides}
6x -12 + 12 = 3x -3 + 12
6x = 3x + 9 {subtract 3x from both side}
6x - 3x = 3x - 3x + 9
3x = 9 {Divide both sides by 3}
3x/3 = 9/3
x = 3

Answer: 9
Step-by-step explanation: so first you remove the ( ) because they’re useless in this then once you remove then Since two opposites add up to zero, remove them from the expression then you only get left with 9.
BASED ON THESE NUMBERS, AND YOUR KNOWLEDGE OF FIBONACCI NUMBERS, IS THE STATEMENT THAT FOLLOWS TRUE OR FALSE? F(N+2) IS EXACTLY EQUAL TO THE SUM OF THE FIRST N TERMS OF THE FIBONACCI SEQUENCE.
A. TRUE
B. FALSE
Answer:
false
Step-by-step explanation:
which three statements are true about the line segment CB
it's the radius of the circle
it is the circumference of the circle
it is a cord
it is 6cm long
it is diameter of the circle
it is 7cm long
it is 1.75cm long
Answer:
1. it is 7 cm long
2. it is a chord
3. it is the diameter of the circle
Step-by-step explanation:
Here, we want to select three statements that are true about CB
From what we have, CB runs from one edge to the other, passing through the center of the circle
Also, as we can see, AD is a radius as it is the distance from the center of the circle to the circumference; CB is twice this as it is the diameter
The diameter is a chord that passes through the center of the circle and it is a radius
So let us select the correct statements;
1. it is 7 cm long
2. it is a chord
3. it is the diameter of the circle
Lawrence found a shirt he liked in the clearance aisle for 15% off the original price. If the original price of the shirt was $35, how much will Lawrence be saving when he buys it?
Answer:
15/100 x 35 = $5.25
Of means multiplication
Always consider a percent as a fraction but it has to be out of 100.
A way to remember that is that the word "cent" means 100. So you multiply the two numbers (divide at the end 21/4 = 5.25)
HELPP ASAP I WILL GIVE 14 POINTS
Given:
A box-and-whisker plot of data set.
To find:
The percentage of the data values that are greater than 80.
Solution:
From the given box-and-whisker plot, it is clear that:
Minimum value = 8
First quartile = 60
Median = 68
Third quartile = 80
Maximum value = 92
We know that the 25% the data value are greater than or equal to third quartile because the third quartile divides the data in 75% to 25% and 80 is the third quartile.
Therefore, about 25% of the data values that are greater than 80.

Eighteen students decide they don't want to be
rescued and want to continue to live in the
jungle. If this represents 40% of the students,
how many students want to be rescued?
Type your answer into the box to continue.
Answer: 45
Step-by-step explanation:
18 = 40% N
18 = 0.4 N
Divide both sides by 0.4
N = 45
There are 45 students want to be rescued.
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.
Given that;
Eighteen students decide they don't want to be rescued and want to continue to live in the jungle.
And, This represents 40% of the students.
Now,
Let the number of students want to be rescued = x
So, We can formulate;
⇒ 40% of x = 18
Solve for x as;
⇒ 40/100 × x = 18
⇒ 40x = 1,800
⇒ x = 1800/40
⇒ x = 45
Thus, The number of students want to be rescued = 45

can u help me finish setting up the tangent ratio?
This is because
tan(angle) = opposite/adjacent
For the reference angle 38, we have 10 as the opposite side and x as the adjacent side.
Therefore, tan(38) = opposite/adjacent = 10/x
Side note: if you solve for x, you should get roughly x = 12.799
Kade has $45 in savings and wants to purchase a video game console for $250. He has a coupon for 10% off, and sales tax is 8.25%. In order to be financially responsible, Kade wants to wait until he has enough in savings to not have to borrow money. If Kade is able to save $45 each week, what is the minimum number of weeks Kade should save before making his purchase?
Answer:
5 weeks
Step-by-step explanation:
First, solve for the total cost of the game console after tax and a coupon
Solve for tax:
$250 × 8.25%
Convert percentage into a decimal
250 × 0.0825
20.625
Round up to nearest hundredths place (because the unit is dollars)
20.63
Add this tax onto the original cost
250 + 20.63
270.63
Subtract the coupon from the total
270.63 - 10
260.63
Total cost is $260.63
Now let's find how much Kade needs to save so set up an equation
Variable x = number of weeks
45 + 45x = 260.63
Subtract 45 from both sides to isolate the variable
45x = 215.63
Divide both sides by 45
x = 4.791777...
Round up to nearest whole number (because units are weeks)
x = 5 weeks
