Answer:
Each girl should sell at least 77 boxes.
Step-by-step explanation:
Considering the number of boxes and how many girls will them, just take [tex]\dfrac{100}{13} \approx 77[/tex]
The exact result is [tex]\dfrac{100}{13} = 76.923...[/tex], but [tex]76 \cdot 13 = 988[/tex] and [tex]77 \cdot 13 = 1001[/tex], therefore, 76 cannot be the result. So, each girl should sell at least 77 boxes.

if a student is selected at random, find the probability the student is a junior. round to the nearest whole percent! i’m not good at probability so an explaination would be appreciated!!!
Answer:
the answer is 40%.
Step-by-step explanation:
probability= total number of juniors all over total number.
that is , 8
20
2
5
rounding it the nearest whole percent is
2 × 100
5
40%.
The probability that the selected student is a junior is 27%.
What is the probability of an event?The probability of an event is the ratio of the number of outcomes favorable to the event to the total number of outcomes for the event. This represents the chance for the event to take place.
If A is the event, n is the number of outcomes favorable to the event and S is the total number of outcomes, then the probability of the event A is given as:
P(A) = n/S.
How do we solve the given question?We are given a two-way table showing the number of freshmen, sophomores, juniors, and seniors in the class with respect to their gender.
We are asked to find the probability of selecting a junior student while picking a random student from the class.
Let the event of selecting a junior student from the class be A.
Number of favorable outcomes to event A (n) = 2 + 6 = 8 (junior males + junior females)
Total number of outcomes (students in the class) (S) = 4 + 6 + 2 + 2 + 3 + 4 + 6 + 3 = 30.
∴ The probability that the selected student is a junior is given by:
P(A) = n/S = 8/30
or, P(A) = (8/30)*100% = 26.67% = 27% (rounding to the nearest whole percent).
∴ The probability that the selected student is a junior is 27%.

Answer:
A, D, & F
Step-by-step explanation:
When you distribute, you get 6a + 5a + 5 - 3a + 21.
After combining like terms, you get 8a + 26.
Lastly, all you have to do is figure out which expressions are equivalent to
8a + 26.
A) 8a + 26 = 8a + 26
D) 6a + 5a + 5 - 3a + 21 (combine like terms) = 8a + 26
F) 2(4a + 13) - Simple distribution
2 x 4a = 8a
2 x 13 = 26
2(4a + 13) = 8a + 26

MT is a diameter of OE. Calculate the measure of ZMTH.
A. 17°
B. 34°
C. 68°
D. 146
NEED HELP please, check the picture
Answer:
A. 17°
Step-by-step explanation:
Recall: measure of an inscribed angle = ½(intercepted arc)
Inscribed angle = m<MTH
Intercepted arc = arc MH = 34°
Therefore,
m<MTH = ½(Arc MH)
Substitute
m<MTH = ½(34)
m<MTH = 17°

Suppose you plan to go out for a picnic during spring break. You plan to bring sandwiches, fruits, and drinks. But you only have one picnic basket that can only hold a certain capacity. Each of the items has a value and a size, and you cannot hold all your items in the basket. The picnic basket can hold a total size of 17. Given that the size and the value of items are as follows, how many of each item should you bring to maximize the total value?
Size Value
Sandwich 9 6
Fruit 3 4
Drink 4 6
a) List and explain carefully what the decision variables are.
b) Write out the objective function.
c) Write out the constraints.
d) Write the linear program.
e) Solve the Linear Programming problem using excel. Show your results.
Answer:
e) z (max) = 24
x₁ = x₂ = 0 x₃ = 4
Step-by-step explanation:
a) The problem requires maximizing the total value from sandwich fruits and drink, therefore the objective function is associated to the sum of the values of each value.
We have three variables xi ( x₁, x₂, x₃ ) the values of sandwich, fruits and drink, and we have to maximize such quantities subject to the constraint of size (the capacity of the basket)
b) z = 6*x₁ + 4*x₂ + 6*x₃ Objective Function
Constraint :
basket capacity 17
9*x₁ + 3*x₂ + 4*x₃ ≤ 17
General constraints:
x₁ ≥ 0 x₂ ≥ 0 x₃ ≥ 0 all integers
e) z (max) = 24
x₁ = x₂ = 0 x₃ = 4
NOTE: Without the information about fractional or decimal feasible solution we decided to use integers solution

Which inequality represents all values for X for which the product below is defined?
Answer:
x ≥0
Step-by-step explanation:
Given the product:
√(5x)*√(x+3)
The function has to be defined if x ≥0
Hence;
√(5x)*√(x+3)≥0
Find the product
√(5x)(x+3)≥0
Square both sides
(5x)(x+3)≥0
5x≥0 and x+3≥0
x≥0/5 and x ≥0 - 3
x ≥0 and x ≥-3
Hence the required inequality is x ≥0

(231 lb)/(7 wk) = 33 lb/wk
The pumpkin gained 33 pounds per week.
__
In the 3 weeks after the pumpkin plant was chosen, it would have gained 3×33 = 99 pounds. It weighed 141 pounds at that point, so must have had an initial weight of 141 -99 = 42 pounds at t=0. The weight of the pumpkin can be modeled as ...

Solve 5(11x - 2) = 155
Answer:
3
Step-by-step explanation:
5(11x-2) = 155
⇔ 55x - 10 = 155
⇔ 55x = 155 + 10
⇔ 55x = 165
⇔ x = [tex]\frac{165}{55}[/tex]
⇔ x = 3
Answer:
x=3
Step-by-step explanation:
5(11x - 2) = 155
Divide each side by 5
5/5(11x - 2) = 155/5
11x-2 = 31
Add 2 to each side
11x-2+2 = 31+2
11x=33
Divide by 11
11x/11 = 33/11

Hao Sheng, his father and his grandfather have an average age of 53. One-half of his grandfather's age, plus one-third of his father's age, plus one-fourth of Hao Sheng's age is 65. If 4 years ago, Hao Sheng's grandfather was four times as old as Hao Sheng, then how old are they now?
Answer:
[tex]x = 24[/tex] ---- Hao Sheng
[tex]y =51[/tex] --- His father
[tex]z = 84[/tex] ---- His grandfather
Step-by-step explanation:
Given
[tex]x \to Hao\ Sheng[/tex]
[tex]y \to his\ father[/tex]
[tex]z \to his\ grandfather[/tex]
From the question, we have:
[tex]\frac{x + y + z}{3} = 53[/tex] --- The average of their age
[tex]\frac{z}{2} + \frac{y}{3} +\frac{x}{4}= 65[/tex]
[tex]z - 4 = 4(x - 4)[/tex] --- 4 years ago
Required
Their current age
[tex]z - 4 = 4(x - 4)[/tex]
Open bracket
[tex]z -4 = 4x-16[/tex]
Make z the subject
[tex]z = 4x-16+4[/tex]
[tex]z = 4x-12[/tex]
Multiply [tex]\frac{z}{2} + \frac{y}{3} +\frac{x}{4}= 65[/tex] by 12
[tex]6z + 4y + 3x = 780[/tex]
Substitute [tex]z = 4x-12[/tex] in [tex]6z + 4y + 3x = 780[/tex]
[tex]6(4x - 12) + 4y + 3x = 780[/tex]
[tex]24x - 72 + 4y + 3x = 780[/tex]
Collect like terms
[tex]24x + 3x + 4y = 780+ 72[/tex]
[tex]27x + 4y = 852[/tex]
Substitute [tex]z = 4x-12[/tex] in [tex]\frac{x + y + z}{3} = 53[/tex]
[tex]\frac{x + y + 4x - 12}{3} = 53\\[/tex]
Multiply through by 3
[tex]x + y + 4x - 12 = 159[/tex]
Collect like terms
[tex]x + 4x + y = 159+12[/tex]
[tex]5x + y = 171[/tex]
Make y the subject
[tex]y = 171 - 5x[/tex]
Substitute [tex]y = 171 - 5x[/tex] in [tex]27x + 4y = 852[/tex]
[tex]27x + 4(171 - 5x) = 852[/tex]
[tex]27x + 684 - 20x = 852[/tex]
Collect like terms
[tex]27x - 20x = 852-684[/tex]
[tex]7x = 168[/tex]
Divide by 7
[tex]x = 24[/tex]
Solve for y in [tex]y = 171 - 5x[/tex]
[tex]y =171 -5*24[/tex]
[tex]y =171 -120[/tex]
[tex]y =51[/tex]
Solve for z in [tex]z = 4x-12[/tex]
[tex]z = 4 * 24- 12[/tex]
[tex]z = 96- 12[/tex]
[tex]z = 84[/tex]
