Mrs. Green has to buy enough candy canes for every student in her school to each get one. Candy canes are sold 10 to a box for $3 a box. There are 7 teams in the school, and each team has between 93 and 116 students. a. Is this situation discrete or continuous? How do you know? b. What is the domain and range? (Really think about what you are collecting data on in this question)
Answers
Answer:
a. The situation is discrete for the domain and continuous for the range.
b. i. 651 ≤ x ≤ 812. ii. $ 195.3 ≤ x ≤ $ 243.6.
Step-by-step explanation:
a. This is because we can only have a whole number of students which in turn leads to a whole number of candies. Also, since the cost of each candy box is $ 3/10 = $ 0.3, it is a real number. So, the total cost of candy will also be a real number. Thus, the situation is discrete for the domain and continuous for the range.
b. i. Let x be the number of students which also equals number of candies to be bought. Since there are 7 teams and between 93 and 116 students per team, the minimum number of students is 93 × 7 = 651 and the maximum number of students is 116 × 7 = 812. So, the domain, the number of candies is 651 ≤ x ≤ 812.
ii. The range of the function is the cost of the candies. Since the cost of the candies is $ 3 per box and there are 10 per box, each candy costs $ 3/10 = $ 0.3. So the total cost of candies C = cost per candy × number of students = $0.3x.
So, the range of the candies is the minimum and maximum values of students times $ 0.3. So, 651 × $ 0.3 ≤ x ≤ 812 × $ 0.3 = $ 195.3 ≤ x ≤ $ 243.6

Answers
Answer:
J = 7.5
Step-by-step explanation:
* This is going off of the estimate that the = sign means the equation is = to 0, as there is no value after the equal sign. *
First, start off by adding all of the like numbers.
11 + (-3) + 7 = 8 + 7 = 15
- 1/8 j - 3/8 j = - 4/8 j.
Combining those two sums, we get:
15 - 4/8 j = 0
Subtract 15 from both sides,
-4/8 j = -15
Simplify -4/8 to -1/2, and then to -0.5
-0.5j = -15
Divide.
-15/-0.5 = 7.5
When you divide a negative number by another negative number, you get a positive. Therefore, the answer is J = 7.5
If the number after the = sign IS NOT 0, then when you get to 15 - 0.5j, just do the steps but with a number that isn't 0.

Answers
Gallons (volume) and feet (length) are not compatible units. I guess you mean cubic feet.
Apparently, 1 gal = 231 in³, so
32 gal/min
= (32 gal/min) • (231 in³/gal) • (1/12 ft/in)³ • (1/60 min/s)
= (32 • 231) / (12³ • 60) ft³/s
= 77/1080 ft³/s
≈ 0.0713 ft³/s

(-4, -7) and (-6, 9) in slope-intercept form. Show work
Answers
Answer:
Equation of line in slope-intercept form is: y = -8x-39
Step-by-step explanation:
Given points are:
(-4, -7) and (-6, 9)
The slope-intercept form is given by the equation
[tex]y = mx+b[/tex]
Here m is the slope of the line and b is the y-intercept.
m is found using the formula
[tex]m = \frac{y_2-y_1}{x_2-x_1}[/tex]
Here
(x1,y1) = (-4-7)
(x2,y2) = (-6,9)
Putting the values in the formula
[tex]m = \frac{9+7}{-6+4} = \frac{16}{-2} = -8[/tex]
Putting slope in general equation
[tex]y = -8x+b[/tex]
Putting (-6,9) in the equation
[tex]9 = -8(-6)+b\\9 = 48+b\\b = 9-48\\b = -39[/tex]
Putting the value of b we get
[tex]y = -8x-39[/tex]
Hence,
Equation of line in slope-intercept form is: y = -8x-39
