One number is 2 times a first number. A third number is 100 more than the first number. If the sum of the three numbers is 468 , find the numbers
Answer:
Step-by-step explanation:
Givens
Let the first number = x
Let the second number = 2x
Let the third number = x + 100
Total = 468
==============
Solution
x + 2x + x + 100 = 468 Combine the xs
4x + 100 = 468 Subtract 100 from both sides
4x = 468 - 100
4x = 368 Divide by 4
x = 368/4
x = 92
===============
Answer
First number = 92
Second num = 2 * 92= 184
Third number = 92 + 100= 192
Total 468

Question 10(Multiple Choice Worth 1 points)
(05.02 MC)
The table below shows data from a survey about the amount of time students spend doing homework each week. The students were in either college or high school:
High Low Q1 Q3 IQR Median Mean σ
College 50 6 8.5 17 8.5 12 15.4 11.7
High School 28 3 4.5 15 10.5 11 10.5 5.8
Which of the choices below best describes how to measure the spread of these data?
(Hint: Use the minimum and maximum values to check for outliers.)
Both spreads are best described by the IQR.
Both spreads are best described by the standard deviation.
The college spread is best described by the IQR. The high school spread is best described by the standard deviation.
The college spread is best described by the standard deviation. The high school spread is best described by the IQR.
Answer:
The college spread is best described by the IQR. The high school spread is best described by the standard deviation.
Step-by-step explanation:
The college data has large outliers which skews the data, therefore the IQR is better measure of spread.
The high school data does not appear to be skewed so the standard deviation is fine as a measure of spread.

Answer:
A.) 3/4
Step-by-step explanation:
You can find this by dividing the distance from point Z to point Y by the distance of point X to point Y. The distance from Z to Y is 6 and the distance from X to Y is 8, so that means that the slope is 6/8, which simplifies to 3/4.

The two prisms below are similar. What is the value of x?
24
4
16
A. 4
B. 24
C. 16
D. 1
Answer:
A
Step-by-step explanation:
Since the prisms are similar then the ratios of corresponding sides are equal, that is
[tex]\frac{16}{4}[/tex] = [tex]\frac{x}{1}[/tex] ( cross- multiply )
4x = 16 ( divide both sides by 4 )
x = 4 → A
The value of x on the prism is 4.
What are Similar Figures?Similar figures are those figures which are having the same shape, but the sizes are different.
Given are two prisms.
We have to find the length of x.
Given that they are similar.
So the ratio between their dimensions is equal.
So,
x / 1 = 16 / 4
x = 4
Hence the value of x is 4.

-1/3 (n + 15) = -2
46 = -6t -8
Urgent. Please answer ASAP. Thanks guys!
Answer:
n= -9, t= -9
Step-by-step explanation:
1) -1/3(n+15)=-2
-1/3×n+-1/3×15=-2
-1/3×n -5= -2
-1/3 n-5+5= -2+5
-1/3×n=3
3/-1×-1/3×n=3/-1×3
n= -9
2) 46 = -6t -8
−6t−8=46
−6t−8+8=46+8
−6t=54
Divide both sides by -6
t=-9
