b. because it would be more difficult to ask 20,000 people a question than 100 or 2000 people. it would take more time/effort/energy/resorces.
44 is 2 thirds of a number, what is the number?
Answer:
The number is 66
Step-by-step explanation:
Since 44 is two thirds of a number, 44/x = 2/3
If you multiply the numerator and denominator of 2/3 by 22, you get 44/66
Since 44/x = 44/66,
x=66
If 44 is 2 thirds of a number, then the number is 77.
We can solve this problem by setting up the following equation:
2/3 * x = 44
Where x is the unknown number.
To solve for x, we can multiply both sides of the equation by 3/2. This gives us the following equation:
x = 44 * (3/2)
Simplifying the right side of the equation, we get x = 77.
Therefore, the number is 77.
Here is the solution in more detail:
Define the variables.
x: The unknown number.
Set up the equation.
We know that 2/3 of the number is 44, so we can set up the equation 2/3 * x = 44.
Solve for x.
To solve for x, we can multiply both sides of the equation by 3/2. This gives us the equation x = 44 * (3/2).
Simplifying the right side of the equation, we get x = 77.
The answer.
Therefore, the number is 77.

Jason was hired to mow a lawn that covers an area of 2 3/4 acres. It took him 4 1/8 hours to complete the job. What was his unit rate in hours per acre?
In this activity, you will multiply the numerator in a complex fraction by the reciprocal of the denominator to calculate a unit rate involving fractions. Answer the questions below to calculate Jason’s unit rate as he mowed.
Answer:
2 3/4 = 11/4
4 1/8 = 33/8
11/4 / 33/8 = 11/4 * 8/33 = 88/132 = 2/3

Hi, I still have to struggle with this and it's due later today! If someone could show me how to do it I will make you're a brain list and give you 28 points I need help w part C to E. I would appreciate it.
Answer:
C) Explain how the equations are equal and just prove it with a check or just plug in a number like for ex: x=1 and I checked with both and it equals out.
d) Use inverse operations (or you can say do the order of operations in reverse and then use invers operations), provide an example if you think what you said doesn’t make sense, like for
Ex: 2x-1=43+5x
2x=44+5x (add the -1)
-3x=44 (subtract 5x to both sides)
X=44/-3 (isolate the variable by dividing 3 on both sides)
An example is always better
E) Just use inverse operations and solve it like what you would normally do

Romb ma obwód równy 32 cm. Jakie jest pole tego rombu, jeżeli jego wysokość ma 3 cm?
Answer:
24 cm²
Step-by-step explanation:
Z zadanego powyżej pytania uzyskano następujące dane:
Obwód (obwód) = 32 cm
Wysokość (h) = 3 cm
Obszar rombu (A) =?
Następnie określimy długość boku rombu. Można to uzyskać w następujący sposób:
Obwód, czyli obwód (P) = 32 cm
Strona (y) =?
P = 4 s
32 = 4 s
Podziel obie strony przez 4
s = 32/4
s = 8 cm
Stąd długość boku rombu wynosi 8 cm
Na koniec określimy obszar rombu w następujący sposób:
Długość boków = 8 cm
Wysokość (h) = 3 cm
Obszar rombu (A) =?
A = sh
A = 8 × 3
A = 24 cm²
Dlatego obszar rombu jest
24 cm².

What is the smallest integer value of r for which it is true that -2.5 < r < 7?
Answer:
[tex]r = -2[/tex]
Step-by-step explanation:
Given
[tex]-2.5 < r < 7[/tex]
Required
Determine the smallest value or r
For an inequality [tex]a < r < b[/tex]
The smallest value is represented as:
[tex]r>a[/tex]
In this case:
[tex]a = -2.5[/tex]
[tex]b = 7[/tex]
So:
[tex]r>a[/tex] becomes
[tex]r > -2.5[/tex]
r > -2.5 implies that the value of r is greater than -2.5
The smallest integer value after -2.5 is -2
Hence, the smallest value of r in this case is:
[tex]r = -2[/tex]

Which measure Is the sarne as the standard error of the mean?
A. Standard devlation of the population
B. Standard devlation of the sample means
C. mean of the sarnple
D. mean of the population
Answer:
The answer is B.
Step-by-step explanation:
The standard error (SE) of a statistic (usually an estimate of a parameter) is the standard deviation of its sampling distribution.
Formula of the standard error of the means is standard deviation divided by square root of the sample size.
SE = δ/√n
This formula also gives the standard deviation of the sample means.
The answer is standard deviation of the sample (B).
For example, "The notation for standard error can be any one of SE, SEM (for standard error of measurement or mean)."

Answer:
After evaluating the function [tex]f(x)=\frac{x}{7}[/tex] by putting x = 7, we get f(7)= 1
Step-by-step explanation:
We need to evaluate the function [tex]f(x)=\frac{x}{7}[/tex] and find f(7)
For finding f(7) we will put x = 7 in the given function [tex]f(x)=\frac{x}{7}[/tex]
So, putting x= 7 and finding f(7)
[tex]f(x)=\frac{x}{7}\\Put\:x=7\\f(7)=\frac{7}{7}\\f(7)=1[/tex]
So, after evaluating the function [tex]f(x)=\frac{x}{7}[/tex] by putting x = 7, we get f(7)= 1

3 lines are shown. A line with points T, R, W intersects a line with points S, R, W at point R. Another line extends from point R to point U between angle T, R, V. Angle V R W is (3 x) degrees and angle T R S is (2 x + 18) degrees.
What is m∠SRW?
18
54
126
108
Given:
Consider the three point of second line are S, R, V instead of S, R, W.
A line with points T, R, W intersects a line with points S, R, V at point R. Another line extends from point R to point U between angle T, R, V.
[tex]\angle VRW=(3x)^\circ[/tex]
[tex]\angle TRS=(2x+18)^\circ[/tex]
To find:
The m∠SRW.
Solution:
The figure according to the given information is shown below (not to scale).
From the below figure it is clear that, [tex]\angle VRW[/tex] and [tex]\angle TRS[/tex] are vertically opposite angles. So, their measures are equal.
[tex]3x=2x+18[/tex]
Subtract 2x from both sides.
[tex]3x-2x=18[/tex]
[tex]x=18[/tex]
Using x=18 the measure of angle VRW is
[tex]\angle VRW=(3x)^\circ[/tex]
[tex]\angle VRW=(3\times 18)^\circ[/tex]
[tex]\angle VRW=54^\circ[/tex]
Now,
[tex]\angle VRW+\angle SRW=180^\circ[/tex] [Linear pair]
[tex]54^\circ+\angle SRW=180^\circ[/tex]
[tex]\angle SRW=180^\circ-54^\circ[/tex]
[tex]\angle SRW=126^\circ[/tex]
Therefore, the correct option is C.

From where Kiana is standing she must look up at a 50° angle to see the top of a building she backs up 50 feet she will need to look up a 40° angle to see the top of the same building approximately how tall is the building
For this case, what we must do is solve the following system of equations: tan (50) = h / x tan (40) = h / (x + 50)
Solving the system we have: (x + 50) * tan (40) = h (x) * tan (50) = h
Matching: (x + 50) * tan (40) = (x) * tan (50)
Rewriting: x (tan (50) - tan (40)) = 50 * tan (40) x = 50 * tan (40) / (tan (50) - tan (40)) x = 118.9692621
Substituting: h = (x) * tan (50) h = (118.9692621) * tan (50) h = 141.7820455
