B. 1 ÷ 1/3 = 3
C. 1 × 1/3 = 1/3

Enter your answer in the box.
brownies
Answers
Answer:
Part A = B. 1 ÷ 1/3 = 3
Part B = 27 brownies
Step-by-step explanation:
Part A
From the ingredients given in above question:
1/3 cup of butter = 1 batch of brownies
Hence: 1 cup of butter = x
Cross Multiply
1/3 cup of butter × x = 1 cup of butter × 1 batch of brownies
x = 1 cup of butter × 1 batch of brownies/1/3 cup of butter
x = 1 batch of brownies ÷ 1/3
x = 1 batch of brownies × 3/1
x = 3 batches of brownies
Hence, the number brownies Jackson can make with 1 cup of butter Is 3 batches of brownies
Therefore, the equation you can use to solve the problem is Option B. 1 ÷ 1/3 = 3
Part B
If each brownie is 1/9 of a batch, how many brownies did he make?
We know from Part A that Jackson made 3 batches of brownies hence:
1/9 of a batch of brownies = 1 brownie
3 batches of brownies = x
Cross Multiply
1/9 of a batch of brownies × x = 1 brownie × 3 batches of brownies
x = 1 brownie × 3 batches of brownies/ 1/9 of a batch of brownies
x =( 3 ÷ 1/9) brownies
x = ( 3 × 9/1) brownies
x = 27 brownies
Therefore, the number of brownies he made was 27 brownies.

The midpoint of AB is M (2,0). If the coordinates of A are, (-3, 3), what are the coordinates of B?
Answers
Given:
M is the midpoint of AB.
M(2,0) and A(-3, 3).
To find:
The coordinates of point B.
Solution:
Midpoint formula:
[tex]Midpoint=\left(\dfrac{x_1+x_2}{2},\dfrac{y_1+y_2}{2}\right)[/tex]
Let the coordinates of point B are (a,b). Then, using the midpoint formula, we get
[tex](2,0)=\left(\dfrac{-3+a}{2},\dfrac{3+b}{2}\right)[/tex]
On comparing both sides, we get
[tex]\dfrac{-3+a}{2}=2[/tex]
[tex]-3+a=2\times 2[/tex]
[tex]a=4+3[/tex]
[tex]a=7[/tex]
And,
[tex]\dfrac{3+b}{2}=0[/tex]
[tex]3+b=0[/tex]
[tex]3+b-3=0-3[/tex]
[tex]b=-3[/tex]
Therefore, the coordinates of point B are (7,-3).

A health care organization, StarCare, wants to implement a program to increase use of diabetes care services. In the past StarCare has billed insurance companies $350 per group session on cardiac care, a similar service, and thus plans to bill $350 for the diabetes group sessions. Operational expenses for the diabetes care services will be $1,000. Because StarCare is concerned with quality of services, it plans to have a consistent group size of 20 participants. However, the number of group facilitators will vary based on the number of diabetes care group participants. For every participant, it costs StarCare $300 in facilitator salary and other expenses. StarCare will only do one session if it is profitable. Based on this information, what are the (a) fixed costs for the proposed diabetes care program and the (b) the total variable costs for 20 participants?
Answers
Answer:
a) The fixed cost is $1350.
b) Total variable cost is $6000.
Step-by-step explanation:
a) The fixed cost = Operational cost + Insurance company bill.
= $ 1000 + 350 = $1350.
b) Variable cost:-
The number of facilitators = 20.
The salary for each facilitator = $300.
Total variable cost = $300 x 20 = $6000.

cm
Answers
Answer:
Step-by-step explanation:
circumference of a circle = 2πr
9.22 cm = 2*3.14*r
9.22 cm = 6.28*r
9.22 cm /6.28 = r
1.4681 = r
diameter of a circle = 2*r
=2*1.4681
=2.9362
=2.9 cm
Answer:
The Length of diameter of circle is 2.93cm.
Step-by-step explanation:
Given :-Circumference of circle = 9.22 cmTo Find : -Length of diameter, dFormula Used :-Circumference of circle = π × dwhere , d is the length of diameterSolution:-Using formula
Circumference of circle = π × d
substitute the values
9.22 cm = π × d
Using value of π = 3.14
9.22 cm = 3.14 × d
divide each side by 3.14
9.22 cm / 3.14 = 3.14 × d /3.14
2.93 cm = d
Hence, The Length of diameter of circle is 2.93cm.

After the first exam in a statistics course, the professor surveyed 14 randomly-selected students to determine the relation between the amount of time they spent studying for the exam and exam score. She found that a linear relation exists between the two variables. The least-squares regression line that describes this relation is: y=6.3333x+53.0298.
Required:
a. Predict the exam score of a student who studies 2 hours.
b. Interpret the slope.
c. What is the mean score of students who did not study?
d. A student who studies 5 hours for the exam scored 81 on the exam. Is this student's exam score above or below average among all students who studies 5 hours?
Answers
Solution :
Given :
Equation :
y = 6.3333 x + 53.0298
Here, x = number of hours studied
y = the exam score
a). To predict the exam score, we have to replace x in the least square regression line by 2 :
y = 6.3333 x + 53.0298
y = 6.3333 (2) + 53.0298
= 65.6964
Thus he predicted exam score is 65.6964
b). The slope is the co-efficient of x in the least squares regression line :
Slope = 6.3333
The slope represents the average increase in y as x increases by 1.
The exam score increases on average by 6.3333 points per hour studied.
c). The mean score of the [tex]\text{ students who did not study}[/tex] (studied 0 hours) is obtained by replacing x in the least squares regression line by 0 :
y = 6.3333 x + 53.0298
y = 6.3333 (0) + 53.0298
= 53.0298
d). To predict the exam score of a student who studied 5 hours, we replace x in the least squares regression line by 2 :
y = 6.3333 x + 53.0298
y = 6.3333 (5) + 53.0298
y = 84.6963
Thus the average exam score of a student who studied 5 hours is 84.6963
Since the actual exam score 81 is less than the average exam score of 84.6963 the student's exam score is below the average.
