Answer:
$1.89
Step-by-step explanation:
This is a simple unit-rate proportion. We're trying to find the rate of 1 gallon to unknown money. To get 1 gallon, we have to divide it by 13, because that's the total gallons we start with.
13 = 24.57
/13
_________
1=24.57
Whatever we do to one side of the equation, we have to do to the other, so we divide 24.57 by 13, too.
1 = 24.57
/13
_________
1=1.89
For every gallon of gas, you pay 1.89 dollars.
Hope this helps!

A student is assessing the correlation between the average number of hours of internet browsing and average score on a math test. The table below shows the data:
Number of hours of internet browsing
(x) 0 0.5 1 1.5 2 2.5 3 3.5 4 4.5
Score on math test
(y) 95 94 93 92 91 90 89 88 87 86
Part A: Is there any correlation between the average number of hours of internet browsing and average score on the math test? Justify your answer. (4 points)
Part B: Write a function which best fits the data. (3 points)
Part C: What does the slope and y-intercept of the plot indicate? (3 points)
Answers
Yes there is a correlation between the hours of internet browsing and the average score on the math test.
How to solve for the correlation of variablesa. From the data we have, we can see that as the number of the internet browsing hours increases by 0.5, the test scores fall by 1. So we conclude that there is a correlation.
b. A function that best fits this data is
Test score = f(browsing hours)
This tells us that the test score is a function of a students hours spent browsing the internet.
c. On this table the y intercept is the point where x is at 0. When x is 0, we can see that y is 95. This tells us that a student does his best in the math test if he spends 0 hours on the internet.

For example the age of the Earth (see above) can be written as 4.6 X 109 years. This means that this number has 9 places after the decimal place - filled with zeros unless a number comes after the decimal when writing scientific notation. So 4.6 X 109 years represents 4600000000 years.
Answer:
4.6 × 10⁹
Step-by-step explanation:
I'm not really sure how I would write it down to show how I worked it out.
For me, I usually know in scientific notation, it's usually a decimal number multipled by 10 raised to a certain level of power.
So I just did 4,600,000,000 and turned that into a decimal without its extra zeros, which would be 4.6. Then I worked out how many places the decimal would be from there, which is 9 spaces behind 4.6.

Suppose you borrow money for a year at a simple interest rate of 7.2%. You pay $86.40 in interest. How much have you borrowed?
Answers
Answer:
$1200
Step-by-step explanation:
You want to know the amount borrowed at 7.2% if the simple interest for one year is $86.40.
InterestThe interest formula is ...
I = Prt
where P is the amount borrowed, r is the interest rate, and t is the number of years.
ApplicationUsing the given values, we have ...
86.40 = P·0.072·1
P = 86.40/0.072 . . . . . . divide by the coefficient of P
P = 1200
You have borrowed $1200.
Answer: 1200
Step-by-step explanation: Linear equation. 7.2x = 100(86.40). then divide by 7.2 on each side. x=1200

Find the volume of a pyramid with a square base, where the perimeter of the base is
16.9 cm and the height of the pyramid is 19.6. Round Your answer to the nearest tenth of the cubic centimeter.
Answers
Answer:

Step-by-step explanation:
Volume = ⅓ × area of base ×height. We don't have the area of base, we need to find it.
Perimeter (4×Length) = 16.9 cm
Length = 16.9÷4 = 4.225 cm
Area = L² = 4.225² =

Answer: Range and mean = 8 of both
variance of Set X= 4.7
variance of Set Y= 4.6
Step-by-step explanation:
Two sets of data, set X and set Y are given
a.) Range is the difference of the highest value and the lowest value,
Therefore, Range of set X = 12-4=8
Range of set Y = 12-4=8
Now, Mean of a given data set is the average of all the terms present in the given data set
Mean of set X= Σxif/n = (4+5+6+7+16+18+24)/10 = 8
Mean of set Y= (4+5+7+32+20+12)/10= 8
Therefore, both the data sets has same range and mean.
b.) Standard deviation tells about the variability of the date and is given by,
S.D= σ = √∑ ( X − μ )^2/n
S.D of set X= √(16+9+4+1+0+1+16)/10= √4.7
S.D of set Y= √(16+9+1+0+4+16)/10= √4.6
Variance is the square of S.D, that is, σ^2
Therefore, variance of set X=4.6
variance of set Y= 4.7
c.) The calculated variances of set X and set Y are 4.7 and 4.6 respectively. It implies that the data is more distributed or varied in set X than in set Y. In the other words, data in set Y is more consistent data than of set X.

Step-by-step explanation:
First, I multiplied all of the values to each other, to get the area^3 of the box.
With my answer, 4.73925, I used a longer method, and divided my answer by each answer displayed.
a-4.73925/1/3=12.21775
b-4.73925/2/3=7.108875
c-4.73925/1/2=9.4785
d-4.73925/1=4.73925
I didnt use the full answer from when I multiplied all the answers together, so the answer will be just hardly off a whole number. So, b should be the answer.
If the answers were side lengths, read below
First, I multiplied all of the values to eachother, to get the area^3 of the box.
With my answer, 4.73925, I used a longer method, and divided my answer by each answer displayed, after I cubed them.
a-1/3^3=1/27
b-2/3^3=8/27
c-1/2^3=1/8
d-1^3=1
Next, I divided 4.73925 by all of the values listed above.
a-4.73925/1/27=127.9595
b-4.73925/8/27=15.9949
c-4.73925/1/8=37.914
d-4.73925/1=4.73925
After I had completed this process, b is still the closest to a whole number, So, b is my answer.

Firstly, brainly allows 1 question per question. So do not try this again.
Lets make the fractions all like terms.
242/4 - 37/4=205/4. Lets now make this a mixed fraction.
By doing 205/4, we find out that 4 goes in less than 51 times.
1. 51 1/4.
2. 11/2 = 66/12.....so 66/12 - 29/12= 37/12. Make it mixed fraction: 3 1/12.
3. 36/5=72/10. 72/10 - 37/10 = 35/10. As a mixed it is 3 1/2
4. 35/3 - 17/2 can be rewritten by finding their GCM (Greatest Common Multiple). In this case it is 6.
