Molique is taking a road trip every time he stops for gas he records the number of miles he has driven and the number of gallons of gasoline his car has used the number of miles Millie drives is proportional to the number of gallons of gasoline his car uses how fill in the missing values in the table
Answers
Based on the fact that the distance driven is proportional to the gallons used, the missing figure is 8 gallons.
Why is 8 gallons the missing figure?The question is incomplete so I will use a similar question to explain the concept.
If the number of miles driven is proportional to the number of gallons used then you can find the number of miles driven per gallon as:
= Number of miles driven / Number of gallons used
= 112 / 4
= 28 miles per gallon
You can also use other entries in the table to get the same answer:
= 280 / 10 gallons
= 28 miles per gallon
If 224 miles have been driven, the number of gallons used would therefore be:
= Number of miles driven / Miles per gallon
= 224 / 28
= 8 gallons

Profit = Total Revenues - Total cost
Given that,
you and Omar are talking about which two frozen treats would be best to sell.
Omar claims that because 50% of the frozen treats sold in Week 1 were sundae cups, the sundae cups accounted for 50 % of the profit.
Total number of the frozen treats = 100%
If 50% of the frozen treats sold in Week 1 were sundae cups, then the profit of the frozen treats will be 50% of the total which came from sundae cups.

What is the answer to this 3x+17=-2x-13???
Answers
Answer:
x = -6
Step-by-step explanation:
3x + 17 = -2x - 13
==> add 2x to both sides
5x + 17 = - 13
==> subtract 17 from both sides
5x = -30
==> divide both sides by 5
x = -6
move like terms (remember to change signs)
3x + 2x = -13 -17
5x = -30
get x to equal to the following
x = -30 / 5
x = -6

There will be $793 in the account after 4 years.
Which statements are true about the data sets? check all that apply. set a is symmetrical. set b has the same mean and median. set b is right skewed. set a is left skewed. the median of set a is larger than the mean of set a.
Answers
1) The mean of set A is larger than the mean of set B.
2)The median of set A is larger than the median of set B.
A = {10, 12, 12, 6, 8, 5, 4, 10, 8, 10, 12, 12, 6}
B = {8, 8, 8, 7, 9, 7, 9, 10, 6, 8}
What is the mean?Mean is the ratio of the sum to the total number of observations.
Mean of set A = 115/13
Mean of set B =80/10 =8
So, the mean of set A is larger than the mean of set B.
Arranging both the sets in ascending order
A = {4, 5, 6, 6, 8, 8, 10, 10, 10 12, 12, 12, 12 }
Median of set A = middle term = 7th term = 10
Similarly, the median of set B =8
So, the median of set A is larger than the median of set B.
Thus, 1) The mean of set A is larger than the mean of set B.
2)The median of set A is larger than the median of set B.

Simplify both equations
4x + 1 = 5x-15y - 6
-x + 15y = -7
3x + 18y + 4 = 9y + 19
3x + 9y = 15

(easier for adding both equations)
-3x + 45y = -21
3x + 9y = 15
Add both equations
x cancels out
54 y = -6

The expected value is 50 then Carmen’s prediction is low because 200 times one-fourth is 50. Then the correct option is B.
How to calculate the expectation value?Expectation can be taken as a weighted mean, weights being the probability of occurrence of that specific observation.
Thus, if the random variable is X, and its probability mass function is given as
[tex]E(X) = \sum_{i=1}^n( f(x_i) \times x_i)[/tex]
(n is the number of values X takes)
Carmen is going to roll an 8-sided die 200 times.
She predicts that she will roll a multiple of 4 twenty-five times.
The sample will be
Total event = 8 {1, 2, 3, 4, 5, 6, 7, 8}
Then the favorable event will be to roll an 8-sided die and get a multiple of 4. Then we have
Favorable event = 2 {4, 8}
Then the probability will be
[tex]\rm P = \dfrac{2}{8} = \dfrac{1}{4}[/tex]
A dice is rolled 200 times, then by the binomial theorem we have the expected value will be

On the histograms, each interval represents possible integer values from the left endpoint up to but not including the right endpoint. (a) The median teaching year for one high school is 6, and the median teaching year for the other high school is 7. Identify which high school has each median and justify your answer. (b) An additional 18 teachers were not included with the data recorded from the 200 teachers at High School A. The mean teaching year of the 18 teachers is 2. 5. What is the mean teaching year for all 218 teachers at High School A
Answers
The mean teaching year for all 218 teachers at High School A is 7.73 if the teaching year is recorded as an integer, with first-year teachers recorded as 1, second-year teachers recorded as 2, and so on.
What is a histogram?It is defined as the numerical data representation in the graph with the help of a bar without space. The histogram gives an idea about the data's approximate distribution.
We have two histograms representing the teaching year with frequency.
From the first histogram the two reactangles represents = 45+48 = 93
From the second hisogram = 79+34 = 113
Median divided into two equal parts.
From the data:
The first graph has 200 points
The second graph has 221 points
The first graph median should be near the 100th data point
The second graph median should be the 111th data point
We obtain 93 from rectangles on a, which is less than 100, and these two rectangles include 1-4 and 4-7 (not including?) As a result, we might argue that this data covers 1-6.
We clearly need more values after we reach the medians, thus we must include the following interval. As a result, in a medium, 7 should be used.
The same reasoning applies to b), where the first two rectangles yield 113 and the median is the 111th datum point. We don't need to add these two rectangles because it includes them. So, for this median, the next interval (7-10) must be 6.
For part (b):
Mean of 18 = 2.5
= 2.5×18 ⇒ 45
Mean of 200 = 8.2
= 200×8.2 ⇒ 1640
New mean = Total/number of observation
= (45+1640)/(200+18)
= 1685/218
= 7.729
= 7.73
Thus, the mean teaching year for all 218 teachers at High School A is 7.73 if the teaching year is recorded as an integer, with first-year teachers recorded as 1, second-year teachers recorded as 2, and so on.

Answers
Answer:
y = -1x + 3 or y = -x + 3 (**That is the last option which is D**)
Step-by-step explanation:
You need to do slope-intercept formula and the slope formula.
The Slope-Intercept Formula: y=mx+b
The Slope Formula: y2 - y1 / x2-x1
Your coordinates:
(-1,4) and (1,2)
2 - 4/1- (-1)
-2/2
Simplified is -1
Your "m" in the slope-intercept formula is -1
Formula: y=-1x + b
Now, you need to find the Y-Intercept which is the "b"
Using our slope-intercept formula, you need to plug in "x1" and "y1"
4 = -1(-1) + b
4 = 1 +b
4-1 = b
3 = b
So your equation is:
y = -1x + 3 or y = -x + 3
