The final point on the number line will be at 2/3 from 0 point, which represents the value of the expression -2/6 + (5/6).
Modelling -2/6 + (5/6 on the number lineTo correctly model the expression -2/6 + (5/6) on a number line, we can use the following steps:
Start at 0 on the number line.Move to the left by 1/3. This represents the value of -2/6 which is equivalent to -1/3.Move to the right by 5/6. This represents the value of 5/6.The final point on the number line will be 2/3 to the right of the point (-1/3) which we reached in step 2, this represents the sum of -2/6 and 5/6, which is the final result.So to model the expression -2/6 + (5/6) on a number line, we start at 0 and move 1/3 to the left, to represent -2/6, and then move 5/6 to the right to represent 5/6.

For 36 people with candy corn = 3.9 cups
For 4 people with candy corn = 0.43 cups
For 6 people with candy corn = 0.65 cups
Step-by-step explanation:
1. Set up a proportion to find how many cups it takes to feed 36 people peanuts given that it takes 3 cups to feed 12 people. This means that the proportion would be 3/12 = x/36. Cross multiply. This would give you 12x = 108. Divide 12 on both sides. Now, the equation is solved since you found out x = 9 cups.
2. Set up a proportion to find how many cups it takes to feed 4 people peanuts given that it takes 3 cups to feed 12 people. This means that the proportion would be 3/12 = x/4. Cross multiply. This would give you 12x = 12. Divide 12 on both sides. Now, the equation is solved since you found out x = 1 cup.
3. Set up a proportion to find how many cups it takes to feed 6 people peanuts given that it takes 3 cups to feed 12 people. This means that the proportion would be 3/12 = x/6. Cross multiply. This would give you 12x = 18. Divide 12 on both sides. Now, the equation is solved since you found out x = 1.5 cups.
4. Set up a proportion to find how many cups it takes to feed 4 people M & Ms given that it takes 2 cups to feed 12 people. This means that the proportion would be 2/12 = x/4. Cross multiply. This would give you 12x = 8. Divide 12 on both sides. Now, the equation is solved since you found out x = 0.67 cups.
5. Set up a proportion to find how many cups it takes to feed 6 people M & Ms given that it takes 2 cups to feed 12 people. This means that the proportion would be 2/12 = x/6. Cross multiply.

5. Set up a proportion to find how many cups it takes to feed 36 people raisings given that it takes 0.5 cups to feed 12 people. This means that the proportion would be 0.5/12 = x/36. Cross multiply. This would give you 12x = 46.8. Divide 12 on both sides. Now, the equation is solved since you found out x = 3.9 cups.
6. Set up a proportion to find how many cups it takes to feed 4 people raisins given that it takes 0.5 cups to feed 12 people. This means that the proportion would be 0.5/12 = x/4. Cross multiply.

A student is graduating from college in 12 months but will need a loan in the amount of $10,958 for the last two semester. The student may receive either an unsubsidized Stafford Loan or a PLUS Loan. The terms of each loan are:
Unsubsidized Stafford Loan: annual interest rate of 3.85%, compounded monthly, and a grace period of six months from time of graduation
PLUS loan: annual interest rate of 4.15%, compounded monthly, with a balance of $11,421.51 at the time of repayment
Which loan will have a higher balance, and by how much at the time of repayment?
Answers
Answer:
To determine which loan will have a higher balance at the time of repayment, we need to calculate the balance of each loan after the interest has been compounded over the repayment period.
The unsubsidized Stafford Loan has an annual interest rate of 3.85% and a grace period of six months from the time of graduation. This means that the loan will accrue interest for a total of 12 months - 6 months = 6 months.
The balance of the unsubsidized Stafford Loan at the time of repayment can be calculated using the following formula:
Balance = Principal * (1 + Interest rate / Number of compounding periods per year)^(Number of compounding periods)
Plugging in the given values, we have:
Balance = $10,958 * (1 + 0.0385 / 12)^(6) = $10,958 * (1.003125)^(6) = $11,283.16
The PLUS loan has an annual interest rate of 4.15% and a balance of $11,421.51 at the time of repayment.
The balance of the PLUS loan at the time of repayment can be calculated using the same formula:
Balance = $11,421.51 * (1 + 0.0415 / 12)^(6) = $11,421.51 * (1.003479)^(6) = $11,973.54
Therefore, the PLUS loan will have a higher balance at the time of repayment, by $11,973.54 - $11,283.16 = $690.38.

1,416 cm²Step-by-step explanation:
There are various lines dividing this figure into shapes, such as rectangles and triangles; this makes it easier to find the area.
To find the area of a triangle, multiply the base and the height, then multiply the product by 1/2.To find the area of a rectangle, multiply the width by the length.First, find the area of the triangles.
In this figure, there are two triangles with heights of 12 and bases of 18.
[tex]12 * 18 = 216[/tex]
Then, multiply the product by 1/2.
[tex]216 * 1/2 = 108[/tex]
There are two triangles, so multiply, the product, 108, by 2.
[tex]108*2 = 216[/tex]
The area of both combined triangles is 216 cm; the area of a single triangle is 108 cm.
Secondly, find the area of the rectangles.
There are two rectangles with widths of 25 and lengths of 15.
[tex]25*15 = 375[/tex]
There are two rectangles, so multiply the product, 375, by 2.
[tex]375*2 = 750[/tex]
The area of both rectangles combined is 750 cm; the area of a single rectangle is 375 cm.
Lastly, we find the area of the rectangle in the middle.
This rectangle has a length of 18 and a width of 25.
18[tex]18*25 = 450[/tex]
The area of this rectangle is 450 cm.
Lastly, add the areas of all the shapes.
[tex]108 + 108 + 375 + 375 + 450 = 1,416.[/tex]
Therefore, the area of this figure is 1,416 cm².

A sample with size n=10 has x¯=508.5, and s=21.5. The dotplot for this sample is given below.
Indicate whether or not it is appropriate to use the t-distribution.
Yes / No
Answers
Answer:
1) Yes
2) No
Step-by-step explanation:
In the first test t distribution is appropriate to use because in the dot plot the 16 data points can be seen other the the data points clustered round the mean.
Here degrees of freedom = n-1= 74
S. E= s/√n
S.E= 10.1/ √74= 1.17
For t - distribution it is assumed that the sample is approximately normal which is visible in the dot plot in the first test.
In the second case z test should be applied.
Z test is used when the population standard deviation is not known .
In the second test t distribution is not appropriate to use because in the dot plot only 2 data points can be seen other the the data points clustered round the mean.
For t - distribution it is assumed that the sample is approximately normal which is not visible in the dot plot.

Estimate a 15% tip on a dinner bill of $49.35 by first rounding the bill amount to the nearest ten dollars.
Answers
9514 1404 393
Answer:
$7.50
Step-by-step explanation:
Rounded to the nearest $10, the $49.35 bill becomes $50.
We can find 10% of that amount by moving the decimal point to the left. 10% of $50 is $5.00.
Then 5% of $50 is half of 10%, so is $5/2 = $2.50.
The estimated tip of 15% is the sum of 10% and 5% of the bill, so is ...
15%($50) = 10%($50) +5%($50) = $5.00 +2.50 = $7.50
The estimated 15% tip is $7.50.
To calculate the cost of painting his silo, a farmer must find its height. The farmer uses a cardboard square to line up the top and bottom of the silo as shown in the diagram below. Approximate the height of the silo, rounded to the nearest foot.
Answers
Answer:
Height of the silo = 18 feet.
Step-by-step explanation:
From the figure attached BC is the length of the silo and the height of the farmer is 5 ft.
Farmer is standing at 8 ft distance from the silo.
From triangle AEC,
tan(∠CAE) = CE/AE=5/8
m(∠CAE) = tan-1 (5/8)
= 32°
m∠BAE = 90° - 32° = 58°
From the triangle ABE,
tan58° = BE/AE
BE = 8tan58°
BE = 12.8 ft
Total height of the silo = BE + EC
= 12.8 + 5
= 17.8
≈ 18 ft
Therefore, the total height of the silo is 18 ft.
