Your friend, Broseph, recently graduated from the University of Bros. During his last semester he passed "Introduction to Brotistics with an Emphasis on Tinder Applications". His final project required that he use the Binomial Distribution to calculate the probability of going on a date with more than half of his next 20 Tinder matches.
Broseph found that he had a 64% chance of going on a date with any given Tinder match from historical data.
Broseph should use the ____________ to calculate the probability. Since he is calculating the probability of going on dates with more than half of his next 20 matches--the number of successes is ________ , n = ________ , and p = ______ .
Broseph has a __________ chance of going on dates with at least half of his next 20 Tinder matches. Round the answer to nearest tenth as a percentage i.e. 14.2%.

([tex]\frac{2}{3}[/tex], 2 )
Step-by-step explanation:
Given the 2 equations
3x + [tex]\frac{1}{2}[/tex] y = 3 → (1)
6x - y = 2 → (2)
Multiplying (1) by - 2 and adding to (2) eliminates the term in x, that is
- 6x - y = - 6 → (2)
Add (2) and (3) term by term to eliminate x
- 2y = - 4 ( divide both sides by - 2 )
y = 2
Substitute y = 2 into either of the 2 equations and solve for x
Substituting into (2)
6x - 2 = 2 ( add 2 to both sides )
6x = 4 ( divide both sides by 6 )
x = [tex]\frac{4}{6}[/tex] = [tex]\frac{2}{3}[/tex]
Solution is ( [tex]\frac{2}{3}[/tex], 2 )

Will runs a business that employs 105 staff.
Each member of staff works 35 hours a week and gets an hourly wage of £7.60
The staff have complained that they are not being paid enough and have asked
for a 10% pay rise.
How much will the proposed pay rise cost Will on a weekly basis?
£
Answers
Each employee makes 35 x 7.60 = 266 per week.
105 employees x 266 = 27,930 per week total pay.
27930 x 10 % = 27930 x 0.10 = 2,793 more per week.

Casey is making a flower arrangement with roses r and carnations c the cost of each rose is $0.50 and the cost of each carnation is $0.10 . the arrangement has a total $20. how many of each flower did Casey put in his arrangement
Answers
Answer:
r+c=80
.50r+.10c=20
Step-by-step explanation:
each rose costs $0.50
each carnation costs $0.10
The number of roses is r, and the number of carnations is c.
the arrangement has a total of 80 flowers, so we have that:
r + c = 80
the cost is $20, so we have:
r*0.5 + c*0.1 = 20
so our system of equations is:
r + c = 80
r*0.5 + c*0.1 = 20
and we can also solve it; for this isolate one of the variables in the first equation:
r = 80 - c
now let'r replace this in the second equation:
(80 - c)*0.5 +c*0.1 = 20
40 - c*0.4 = 20
c = 20/0.4 = 50
this means that we have 50 carnations, and the other 30 are roses.

The morning low tide at the beach is 12 inches. After 6 hours, the afternoon high tide is 57 inches. What is the average number of inches the tide changed per hour?
Answers
Answer:
7.5 inches per hour
Step-by-step explanation:
Given that:
Morning low tide at beach = 12 inches
Afternoon tide after 6 hours = 57 inches
Average number of inches tide changed per hour :
(Afternoon tide - morning tide) / number of hours
(57 inches - 12 inches) / 6 hours
45 inches / 6 hours
= 7.5 inches per hour

for m(x)=-2x+7, find the value of x for which m(x)=13
Answers
Answer:
x = -3
Step-by-step explanation:
m(x) = -2x + 7
13 = -2x + 7
6 = -2x
x = -3
The explanation if you need it is since m(x)=13 we get the equation 13=-2x+7. Then we use the equation to find x.
13= -2x+7
-7 -7
6= -2x
— —
-2 -2
-3=x
You then want to check your answer by substituting -3 for x
13= -2(-3) +7
13= 6+7
13=13

Answers
Answer:
14) C (-2, 4)
15) D (-3, -3)
Step-by-step explanation:
-6x + 4y = 28
6x + 9y = 24
-6x + 4y = 28
4y = 28 + 6x
y = 7 + 1.5x
6x + 9y = 24
6x + 9(7 + 1.5x) = 24
6x + 63 + 13.5x = 24
19.5x + 63 = 24
19.5x = -39
x = -2
-6x + 4y = 28
-6(-2) + 4y = 28
12 + 4y = 28
4y = 16
y = 4
____________
4x - 4y = 0
-4x + 3y = 3
4x - 4y = 0
4x = 4y
x = y
-4x + 3y = 3
-4(y) + 3y = 3
-4y + 3y = 3
-1y = 3
y = -3
4x - 4y = 0
4x - 4(-3) = 0
4x + 12 = 0
4x = -12
x = -3
