A line of best fit for this data is C = 51m + 4.4, where Cis the cumulative cell phone cost and m is the number of months.
Using this data, which value is the best prediction of the cumulative cell phone cost after 18 months?
Answer:
cumulative cell phone cost after 18 months = 922.4
Step-by-step explanation:
We are given the line of best fit for the data as;
C = 51m + 4.4
where;
C is the cumulative cell phone cost
m is the number of months.
Now, we are told that m = 18 months
Thus;
C = 51(18) + 4.4
C = 918 + 4.4
C = 922.4
Tthe best prediction of the cumulative cell phone cost after 18 months is 922.4
Given the equation for the line of best fit expressed as C = 51m + 4.4,
where
C is the cumulative cell phone cost
m is the number of months.
We need to predict the cost after 18 months. Substitute m = 18 into the function to get C
C = 51m + 4.4
C = 51(18) + 4.4
C = 918 + 4.4
C = 922.4
Hence the best prediction of the cumulative cell phone cost after 18 months is 922.4

One gram of sugar(S) contains 4 calories and one gram of fat(F) contains 9 calories. If one serving of a food contains 160 calories and has 7 grams of sugar , how many grams of fat are if this serving?
Round your answer to 1 decimal place.
Answer: 14.7 grams of fat.
Step-by-step explanation:
The data we have is:
1g of sugar contains 4 cal
1g of fat contains 9 cal.
Let's define:
S = # of grams of sugar.
F = # of grams of fat.
We know that:
A serving has 160 calories:
S*4cal + F*9cal = 160 cal.
S = 7.
Then we can replace the second equation into the first one, and get:
7*4cal + F*9cal = 160cal
F*9cal = 160cal - 28cal = 132 cal.
F = 132cal/9cal = 14.66...
Now we want to round it to the first decimal place, the next decimal after it is a 6, so we must round up.
F = 14.7
This means that the serving has 14.7 grams of fat.

Mia is mixing nuts and cereal squares to make 12 pounds of trail mix. Nuts cost $8 a pound, and cereal squares cost $3 a pound. If Mia wants her cost for the trail mix to be $5.50 a pound, how many pounds of nuts and how many pounds of cereal squares should she use?
Step-by-step explanation:
If n is pounds of nuts, and c is pounds of cereal squares, then:
n + c = 12
8n + 3c = 5.5(12)
Solve with substitution:
8n + 3(12 − n) = 5.5(12)
8n + 36 − 3n = 66
5n = 30
n = 6
c = 12 − n
c = 6
So Mia should use 6 pounds of nuts and 6 pounds of cereal squares.

Let x represent the dollar amount spent on supermarket impulse buying in a 10-minute (unplanned) shopping interval. Based on a newspaper article, the mean of the x distribution is about $34 and the estimated standard deviation is about $7. A button hyperlink to the SALT program that reads: Use SALT. (a) Consider a random sample of n = 80 customers, each of whom has 10 minutes of unplanned shopping time in a supermarket. From the central limit theorem, what can you say about the probability distribution of x, the average amount spent by these customers due to impulse buying
Answer:
Kindly check explanation
Step-by-step explanation:
Given the following :
Population mean (Mp) = 34
Population standard deviation (sd) = $7
Number of customers (n) = 80 customers
According to the central limit theorem:
If the number of samples is large (usually ≥ 30), then the distribution will be normal and mean of sample will be the same as the mean of population.
Population mean(Mp) = sample mean(Ms)
Mp= Ms
$34 = $34
Sample standard deviation = standard error
Standard Error(SE) = (population standard deviation / √n)
SE = 7 / √80
SE = 7 / 8.9442719
SE = 0.7826237 = $0.78
Hence, sample distribution is Normally distributed with a mean of $34 and standard deviation of $0.78

Step-by-step explanation:
The approximate measure of angle JGH is 70.529°.
Analysis of a right triangle
According to this question, we have a right triangle in which lengths of its hypotenuse ([tex]GH[/tex]), in centimetres, and one leg ([tex]JH[/tex]) are known and we must determine the measure of an angle ([tex]m\angle JGH[/tex]), in degrees.

If the purchase price of a condominium is $123500, down payment of 23%, then the total of down payment and the closing costs is $166725.
What is percentage?Percentage is the number or ratio that is expressed in fraction of 100. It is expressed as %. It shows some part of large quantity.
How to find total?We have been given that the price of condominium is $123500. Down payment is 23% of the total price , it is 23%*123500=$28405
Left out amount will be 123500-28405=$95095.
Points=(2*3+1)/2=7/2
let the percentage of fees be x% then fees percentage will be :
7/2=x/100
x=35%
Fees will be 123500*35%=$43225.
Closing cost=95095+43225=$138320
Total will be 28405+138320
=$166725
Hence the total of down payment and closing cost will be $166725.

find all the points (x,6) that are 10 units from the point P (-17,-2)
Answer:
The points that are 10 units from P(-17,-2) are (-23,6) and (-11,6)
Step-by-step explanation:
Distance Between Points in the Plane
Given two points A(x,y) and B(w,z), the distance between them is:
[tex]d=\sqrt{(z-y)^2+(w-x)^2}[/tex]
It can be also expressed as:
[tex]d^2=(z-y)^2+(w-x)^2[/tex]
Substituting the values of both points, and knowing the distance is 10:
[tex]10^2=(6-(-2))^2+(x+17)^2[/tex]
[tex]100=8^2+(x+17)^2[/tex]
Swapping both sides:
[tex]64+(x+17)^2=100[/tex]
Moving the constants to the right side:
[tex](x+17)^2=100-64=36[/tex]
Taking the square root:
[tex]x+17=\pm 6[/tex]
We get two possible answers:
[tex]x=-17-6=-23[/tex]
[tex]x=-17+6=-11[/tex]
Thus the points that are 10 units from the point P(-17,-2) are (-23,6) and (-11,6)
