A report states that the mean household income last year for a certain rural county was $46,200 and the median was $54,500. If a histogram were constructed for the incomes of all households in the county, would you expect it to be skewed to the right, to the left, or approximately symmetric
Answers
Answer:
skewed to the left
Step-by-step explanation:
A histogram is used to represent data graphically. the histogram is made up of rectangles whose area is equal to the frequency of the data and whose width is equal to the class interval. the frequency is usually on the vertical axis while the class interval is usually on the horizontal axis.
If the mean is greater than the median, the histogram would be skewed to the right
If the mean is less than the median, the histogram would be skewed to the left.
The mean in this question is $46,200 while the median is $54,500. So, the histogram would be skewed to the left

Step-by-step explanation:
f(x): 2x^3 - 3x^2 + 7x - 10
Repace x = -1

Find the percent of real fruit juice in the first brand if the mixture contained 30 percent real fruit juice. Which of the following equations could be used to solve this?
Group of answer choices
a(9)+48(8)17=0.30100
a(9)+0.48(8)17=30100

Second brand:
8 gal 48% contains: 8x40% = 3.84 gal pure juice
5.10 − 3.84 = 1.26 gal
1.26 gal is coming from 9 gal of first brand
The percentage of first brand is:

How many factors of 10 are in 1000, only answer are three, two, four
Answers
Answer:
Step-by-step explanation:
The number 1000 has prime factors: 2, 2, 2, 5, 5, 5.
The factors of 1000 include 1 and combinations of these numbers multiplied together (in any arrangement):
1, 2*2*2*5*5*5 or 1, 1000
1*2, 2*2*5*5*5 or 2, 500
1*2*2, 2*5*5*5 or 4, 250
. . . (You already did these)
But, a “factor” is “a number or quantity that when multiplied with another produces a given number or expression,” so you should consider the following:
How many 1's? How many 5's? How Many 2's? [and any others ...]
1 = 1 0 0
2 = 1 0 1
4 = 1 0 2
8 = 1 0 3
5 = 1 1 0
10 = 1 1 1
20 = 1 1 2
40 = 1 1 3
25 = 1 2 0
50 = 1 2 1
100 = 1 2 2
200 = 1 2 3
125 = 1 3 0
250 = 1 3 1
500 = 1 3 2
1000 = 1 3 3

Step-by-step explanation:
Equation of the circle is

( h, k ) are coordinates of the center
~~~~~~~~~~~~~~~~~~~~~
Coordinates of the center of the circle are

Complete Question
Hal says the volume of the sphere shown below is 36 cm³.Find the correct volume, using 3.14 for π. Round to the nearest hundredth. What was Hal's likely error? Use the drop-down menus to explain your answer.
Radius of the sphere = 3 cm
Answer:
a) The volume of the sphere = 113cm³
b) Hal's likely error was :
He used the wrong formula and did not make use of π = 3.14 in his calculation.
Step-by-step explanation:
a) The Volume of a Sphere = 4/3πr³
The radius of the sphere = 3cm
π = 3.14
The volume of the sphere = 4/3 × 3.14 × 3³
= 113.04 cm³
Approximately to the nearest hundredth = 113cm³.
b) Hal's likely error comes in two forms:
1) He used the wrong formula which is Surface area of the sphere(4πr²) in his calculation instead of the right formula which was the Volume of a Sphere(4/3πr³)
ii) Also he did not use π in his calculation.
This means Hal's calculation=
Surface Area of a Sphere = 4πr²
But Hal's used = 4r²
Where r = 3cm = 4 × (3cm)²= 36 cm³

There is a prism with a pentagonal base the height is 8 cm the area of the pentagonal base is 30.5cm what is the volume of the prism
Answers
Answer:
244 cm³
Step-by-step explanation:
Step 1: Given data
Height of the prism with a pentagonal base (h): 8 cm
Area of the pentagonal base (A): 30.5 cm²
Step 2: Calculate the volume of the prism with a pentagonal base
We have a regular pentagonal prism, that is, the 5 sides of the base are equal and we know the area of the base and the height of the prism. We can calculate its volume using the following expression.
V = A × h
V = 30.5 cm² × 8 cm = 244 cm³

At a high school the average grade for the first semester for all subjects was 79.3. Based on this mean , the principal concludes that half of the grades were 79.3. Higher is her conclusion justified? Why or why not?
Answers
Answer:
That is incorrect. It would be appropriate if the median were 79.3, since the median is the value in the middle (when placing the data in order).
Conclusion of principal about mean is not justified. Mean represents the average of the data. For such conclusion mode is the correct option.
What is mean?
" Mean is defined as the ratio of the sum of all the given numbers in the data to the total numbers of numbers in the data. It is also known as average of the data."
What is mode?" Mode represents the value which occurs maximum numbers of times in the set of data."
According to the question,
Average grade for the first semester for all subjects = 79.3
Based on this mean
Principal concludes that half of the grades scored 79.3.
For example:
There are 5 students 3students score 100 , one student score 48 and another one got 50.
Mean of the class = [tex]\frac{398}{5}[/tex]
= 79.6
Here no student score 79.6.
Principal conclusion is not justified.
Mean is not the correct option to justify maximum number of students marks it is represented by mode.
Hence, conclusion of principal about mean is not justified. Mean represents the average of the data. For such conclusion mode is the correct option.
