Answer:
Hi i know im very late answering this question but i believe the correct option is: b = 2C - a
Step-by-step explanation:
I believe this is the answer because:
2C = the average of 2 test scores combined
A and B = the two scores
were trying to solve for b so what we would do to figure that out is have the average of both test scores and then subtract A which will leave you with only B. therefor the answer is B = 2C - a
hope this helped.

What is the area of a figure?
Answer:
8 x 3 = 24, 24 divided by 2 = 12
I got 3(base of triangle) from subtracting 4 from 7.
12 x 2 = 24(area of two triangles)
16 x 4 = 64(area of long rectangle below)
I got 16 by the given length below, and i got the height from the middle which is the height that says 4.
Add both given areas:
24 + 64 = 88 square inches is your area.

The two-way table shows the results of a recent study on the effectiveness of the flu vaccine.
A 4-column table has 3 rows. The first column has entries Vaccinated, not vaccinated, total. The second column is labeled Positive with entries 465, 485, 950. The third column is labeled Negative with entries 771, 600, 1,371. The fourth column is labeled Total with entries 1,236, 1,085, 2,321.
What is the probability that a randomly selected person who tested positive for the flu is vaccinated?
StartFraction 465 Over 2,321 EndFraction
StartFraction 465 Over 1,236 EndFraction
StartFraction 465 Over 950 EndFraction
StartFraction 465 Over 485 EndFraction
The probability that a randomly selected person who tested positive for the flu is vaccinated is 465/2321.
What is the probability?
Probability determines the chances that an event would happen. The odds the event occurs is 1 and the odds that the event does not occur is 0.
The probability that a randomly selected person who tested positive for the flu is vaccinated = number of people who tested positive and have been vaccinated / total number of people

The nutritional content per ounce of three foods is presented in the table below. If a meal consisting of the three foods allows exactly

Food A:
OZ
Food B:
OZ
Food C:
OZ
Answer:
A = 5 ounces
B = 1 ounces
C = 4 ounces
Step-by-step explanation:
The 3 foods contain exactly 1800 calories but food A is 100 calories, food B is 500 calories and food C is 200 calories. Thus;
100A + 500B + 200C = 1800 - - - (eq 1)
The 3 meals allows exactly 75 grams of protein while A is 5 grams, B is 6 grams, C is 11 grams.
Thus;
5A + 6B + 11C = 75 - - - (eq 2)
The 3 meals allows exactly 5650 milligrams of vitamin C while A is 400 mg, B is 2050 mg and food C is 400 mg. Thus;
400A + 2050B + 400C = 5650 - -(eq 3)
Solving the 3 equations simultaneously online, we have;
A = 5 ounces
B = 1 ounces
C = 4 ounces
Food A is 5 ounces, Food B is 1 ounce, and Food C is 4 ounces and this can be determined by forming the linear equation in three variables.
Given :
The nutritional content per ounce of three foods is presented in the given table.A meal consisting of the three foods allows exactly 1800 calories, 75 grams of protein, and 5650 milligrams of vitamin C.Let the total amount of Food A be 'A', total amount of Food B be 'B', and the total amount of Food C be 'C'.
The linear equation that represents total calories in each food is:
100A + 500B + 200C = 1800
[tex]\rm A =\dfrac{ 1800 - 500B-200C}{100}[/tex]
[tex]\rm A =18 - 5B-2C[/tex] --- (1)
The linear equation that represents total protein in each food is:
5A + 6B + 11C = 75 ---- (2)
The linear equation that represents total Vitamin C in each food is:
400A + 2050B + 400C = 5650 --- (3)
Now, substitute the value of 'A' in equation (2).
[tex]\rm 5(18-5B-2C)+6B+11C=75[/tex]
Simplify the above equation.
90 - 25B - 10C + 6B + 11C = 75
C - 19B = -15
C = 19B - 15 ---- (4)
Now, substitute the value of 'C' in equation (1).
A = 18 - 5B - 2(19B - 15)
A = 18 - 5B - 38B + 30
A = 48 - 43B --- (5)
Now, substitute the value of A and C obtains in equations (4) and (5) in equation (3).
A = 5 ounces
B = 1 ounce
C = 4 ounces

A summer camp has 20 boys and 20 girls. Each day, all camper names are put in a hat, and one name is drawn to receive a prize. What are the odds in favor of boys names being drawn on three out of three nights?
Answer:
[tex]\frac{1}{8}[/tex] or [tex]\frac{9}{78}[/tex]
(see explanation)
Step-by-step explanation:
This problem is asking about compound probability, what is the probability of this even happening three times in a row.
Since there are 20 boy's names and 20 girl's names in the hat, one can say that half of the names in the hat. Assume that after drawing it from the hat, the name is put back into the hat. Therefore, on each night, there is a half-chance of the event happening. To find the probability of the event, one must multiply ([tex]\frac{1}{2}[/tex]) by itself (3) times,
[tex](\frac{1}{2})(\frac{1}{2})(\frac{1}{2})\\=\frac{1}{8}[/tex]
In this case, assume that after each drawing the name is not replaced into the hat. This means that after every draw, one must subtract (1) from both the numerator and denominator of the fraction when the fraction is in the un-simplified form.
[tex](\frac{1}{2})(\frac{19}{39})(\frac{18}{38})[/tex]
Simplify,
[tex](\frac{1}{2})(\frac{19}{39})(\frac{9}{19})[/tex]
[tex]\frac{9}{78}[/tex]
