You basically see if statements are correct or not. Remember this is sample, sample is portion of population so if everything is dome correctly, the results of sample will also display the results of population +- error (standard deviation). So you can just use the sample results to answer questions about the population.
A is correct because social studies has 4 students and reading has 8. Math has twice.
B is correct because reading has 2 and math has 8. Reading is one fourth of math 8*1/4 = 8/4=2.
D is NOT correct because math is 8, social studies is 4. Math is not half of social studies. Social studies is half of math.

[tex]x+4=3(x-2)[/tex]
Answers
Answer:
x = 5
Step-by-step explanation:
x + 4 = 3(x - 2) ← distribute parenthesis by 3
x + 4 = 3x - 6 ( subtract 3x from both sides )
- 2x + 4 = - 6 ( subtract 4 from both sides )
- 2x = - 10 ( divide both sides by - 2 )
x = 5
Answer:
Solution of equation is 5Step-by-step explanation:
In the question we have given an equation that is x + 4 = 3 ( x - 2 ) . And we are asked to solve the question that means we have to find the value of x .
Solution : -
[tex] \longrightarrow \quad \: x + 4 = 3(x - 2)[/tex]
Step 1 : Solving parenthesis on right side :
[tex] \longrightarrow \quad \: x + 4 = 3x - 6[/tex]
Step 2 : Subtracting 4 on both sides :
[tex] \longrightarrow \quad \: x + \cancel{4} - \cancel{ 4 }= 3x - 6 - 4[/tex]
On further calculations we get :
[tex] \longrightarrow \quad \: x = 3x - 10[/tex]
Step 3 : Subtracting 3x on both sides :
[tex] \longrightarrow \quad \: x - 3x = \cancel{3x } - \cancel{3x}- 10[/tex]
On further calculations we get :
[tex]\longrightarrow \quad \: - 2x = - 10[/tex]
Step 4 : Dividing both sides by -2 :
[tex]\longrightarrow \quad \: \dfrac{ \cancel{ - 2}x}{ \cancel{ - 2} } = \cancel{\dfrac{ - 10}{ - 2} }[/tex]
On further calculations we get :
[tex]\longrightarrow \quad \: \red{\underline\red{\boxed{ \frak{ x = 5}}}}[/tex]
Therefore , value of x is 5 .Verifying : -
We are verifying our answer by substituting value of x in given equation. So ,
x + 4 = 3 ( x - 2 )5 + 4 = 3 ( 5 - 2 )9 = 3 ( 3 )9 = 9L.H.S = R.H.S Hence, Verified.Therefore, our answer is correct .

Answers
Answer:
91,300 to 3 s.f.
Step-by-step explanation:
The population is reduced by a percentage 100-7 = 93% ( or 0.93) per year.
So after 5 years thatwould be 300,000(0.93)^5
= 208707
that is 300,000 - 208,706
= 91293
= 91,300 to 3 s.f.

At Central High School, there are 48 football players and 20 cheerleaders. What is the ratio of cheerleaders to football players?
Answers
Answer:
The answer should be 5:12.
Step-by-step explanation:
Since the question asks what's the ratio of cheerleaders to football players, the ratio before simplifying would be 20:48.
So, just find the greatest common divisor of 20 and 48, which would be 4.
20/4 = 5
48/4 = 12
Therefore, the answer to this question and the ratio of cheerleaders to football players is 5:12.

In this question we must determine the volumes of pyramids of circular base and polygonal base (V). All the formulas needed are described below:
Volume of the pyramidV = (π/3) · B · h (1)
Base of the pyramid - CircleB = (π/4) · R² (2)
Base of the pyramid - Regular polygon
B = (n · L²)/(4 · tan 0.5α) (3)
Base of the pyramid - Right triangleB = (1/2) · b · z (4)
Base of the pyramid - RectangleB = b · z
Where:
R - Radiusn - Number of sides of the polygon.l - Side lengthα - Internal angle, in degree.h - Height of the pyramidb - Base of the right triangle/rectangle.z - Length of the right triangle/rectangle.Now we proceed to solve each pyramid:
1) Square, n = 4, α = 90°, L = 14 cm, h = 22 cm
B = 196 cm², V = 1437.333 cm³
2) Circle, R = 3 km, h = 8 km
B ≈ 28.274 km², V = 75,398 km³
3) Right triangle, b = 12 ft, z = 3.7 ft, h = 8 ft
B = 22.2 ft², V = 59.2 ft³
4) Rectangle, b = 23 yd, z = 9 yd, h = 5.7 yd
B = 207 yd², V = 393.3 yd³
5) Circle, R = 9.5 m, h = 12 m
B ≈ 283.529 m², V = 1134.116 m³
6) Regular pentagon, B = 110 mm², h = 11 mm
V = 403.333 mm³
7) Square,n = 4, α = 90°, L = 13 in, h = 7.2 in
B = 169 in², V = 405.6 in³
8) Regular triangle, n = 3, α = 120°, L = 16 ft, h = 24 ft

The least common multiple is the product of all factors in the greatest number of their occurrence.
LCM = 2 x 2 x 3 x 3 x 7
LCM = 2^2 x 3^2 x 7
LCM = 252
The least common multiple of 28, 42 and 63 is 252.
Answer:
LCM = 252.

The red arrow represents an outlier in the given dot plot. which the correct answer would be an option (A).
What is the dot plot?A dot plot, sometimes known as a dot chart, is a sort of basic histogram-like graphic used in statistics for very small data sets with discrete values.
An outlier is a value in a random sampling from a population that is significantly different from the other values. In some ways, this definition leaves it up to the analyst (or a consensus process) to determine what is abnormal. Normal observations must first be characterized before anomalous observations may be identified.
The dot plot is given in the question,
According to the given dot plot,
Most data are clustered around [12, 14], while 24 is distant from this interval.
Thus, the red arrow represents an outlier in the given dot plot.

Answer:
y = 110 degree
x = 70 degree
z = 70 degree
Step-by-step explanation:
Vertical angles are always congruent.
so, the angle with the 110 degree is equal to the angle y.
now we have the measure of y.
as you can see angle y and angle z form a straight light wich means the sum of angle y and angle x is 180 degree
now, to get the measure of angle z,
180 - 110 = angle z
70 = angle z
now we have the measure of angle z
as angle z and angle x are vertical angle, they are congruent.
so angle x = 70
x = 70
z= 70
y = 110
