Step-by-step explanation:
If you add up all the male and female categories, the total is 400
the number of females between 22 and 39 is 51
P(22 - 39) = 51 / 400
P(22 - 39) = 0.1275
I think the answer you want is 51/400

The employees from maintenance go for coffee together every day at 9 a.m. On Monday, Hector paid $4.60 for three cartons of milk, three cups of coffee, and seven
doughnuts. On Tuesday, Guillermo paid $8.30 for four milks, nine coffees, and eight doughnuts. On Wednesday, Anna paid $4.90 for two milks, five coffees, and six
doughnuts. On Thursday, Alphonse had to pay for five milks, two coffees, and eight doughnuts. How much change did he get back from his $10 bill?
Answers
Answer:
The change will be $4.75
Step-by-step explanation:
Given data:
Monday
Total paid = 5.45
milk bought =3
coffee bought = 4
doughnuhts = 7
Tuesday
Total paid = 5.30
milk bought =4
coffee bought = 2
doughnuhts = 8
Wednesday
Total paid = 5.15
milk bought =2
coffee bought = 5
doughnuhts = 6
Thursday
Total paid = X
milk bought =5
coffee bought = 2
doughnuhts = 9
Let milk be m, Let coffee be c and Let doughnuts be d
3m + 4c + 7d = 5.45 (eqaution 1)
4m + 2c + 8d = 5.30 (equation 2)
2m + 5c + 6d = 5.15 (equation 3)
Using equation 1 and equation 2 ( to eliminate m)
3m + 4c + 7d = 5.45 (Multiply the whole equation by 4)
4m + 2c + 8d = 5.30 (Multiply the whole equation by 3)
12m + 16c +28d = 21.8
12m + 6c +24d = 15.9 (Subtracting the two equations)
0m +10c + 4d = 5.9
therefore 10c +4d = 5.9 (equation 4)
Using equation 2 and equation 3 (to eliminate m)
4m + 2c + 8d = 5.30 (Multiply the whole equation by 2)
2m + 5c + 6d = 5.15 (Multiply the whole equation by 4)
8m + 4c + 16d = 10.6
8m +20c +24d = 20.6 (Subtracting the two equations)
0m -16c -8d = -10
-16c -8d = -10 (equation 5)
Solving equation 4 and equation 5( to eliminate d)
10c +4d = 5.9 (Multiply whole equation by 8)
-16c -8d = -10 (Multiply whole equation by 4)
80c + 32d = 47.2
-64c -32d = -40 (Adding the equations)
16c =7.2
therefore c = 0.45
Substituting into equation 4
10(0.45) + 4d = 5.9
4.5 + 4d = 5.9
4d = 5.9-4.5
4d = 1.4
therefore d = 0.35
Substituting c and d into equation 1
3m + 4c + 7d = 5.45
3m + 4(0.45) + 7(0.35) = 5.45
3m + 1.8 + 2.45 = 5.45
3m = 5.45-2.45-1.8
3m = 1.2 therefore m = 0.4
Alphonse has to pay 3m + 2c + 9d
Alphonse change will be 10 - (3m + 2c + 9d) (Substituting m, c and d)
10- (3(0.4) + 2(0.45) + 9(0.35) = 10 -(1.2+0.9+3.15)
which simplifies to 10- 5.25=4.75
The change will be $4.75
A round balloon has a diameter of 7 inches
Which of the following is closest to the number of
cubic inches of air can it hold?
A) 181 in
B) 189 in
C) 196 in
D) 208 in
E) 210 in
None of the above
+3
Answers
Answer:
The right answer is approximately 210.031 cubic inches. (Answer: E)
Step-by-step explanation:
First, we need to convert the diameter ([tex]D[/tex]), in inches, of the round balloon to an entirely decimal mode:
[tex]D = 7\,in + \frac{3}{8}\,in[/tex]
[tex]D = \frac{56 + 3}{8}\,in[/tex]
[tex]D = \frac{59}{8}\,in[/tex]
[tex]D \approx 7.375\,in[/tex]
The volume of the balloon is modelled after the volume function of a sphere ([tex]V[/tex]), in cubic inches:
[tex]V = \frac{\pi}{6}\cdot D^{3}[/tex] (1)
If we know that [tex]D \approx 7.375\,in[/tex], then the volume of the round balloon is:
[tex]V = \frac{\pi}{6}\cdot D^{3}[/tex]
[tex]V = \frac{\pi}{6} \cdot (7.375\,in)^{3}[/tex]
[tex]V \approx 210.031\,in^{3}[/tex]
Hence, the right answer is approximately 210.031 cubic inches.
Kenny and Ben start competing businesses selling hats. Kenny buys supplies, costing $3, before he starts selling his
hats for $0.50 each.
Ben sells his hats for $0.25 each and spent only $1 on supplies. At
what point have they sold the same number of hats and made the
same profit (income minus costs)?
Write your answer as a coordinate point (hats, profit). HELP PLZ WHAT ARE THE EQUATIONS??
Answers
9514 1404 393
Answer:
(8, 1)
Step-by-step explanation:
Let x represent the number of hats sold by each seller.
__
Kenny's cost: $3
Kenny's revenue: $0.50x
Kenny's profit = revenue - cost: y = 0.50x -3
__
Ben's cost: $1
Ben's revenue: $0.25x
Ben's profit = revenue - cost: y = 0.25x -1
__
The profit and sales will be the same when the same (x, y) values satisfy both profit equations.
y = 0.50x -3
y = 0.25x -1
0.50x -3 = 0.25x -1 . . . . . substitute for y
0.25x = 2 . . . . . . . . . . . add 3-0.25x
x = 8 . . . . . . . . . . multiply by 4
y = 0.25x -1 = 2 -1 = 1 . . . using Ben's profit equation
The profit and sales will be the same for ...
(hats, profit) = (8, 1)

A swimming team from East High School is participating in a swim meet with, with three swimmers competing in the
butterfly stroke race.
There are 15 total swimmers competing in the butterfly stroke race.
What is the probability that two East High School swimmers finish first and second in the race?
Enter your answer as a simplified fraction.
Answers
Answer:
1/35
Step-by-step explanation:
P= 6 *13! / 15! = 1/35
The probability of two east high school swimmers to come first and second is 1/35.
How to calculate probability?
First, let us calculate the number of desired outcomes:
The first position has 3 possibilities and 2nd position has 2 possibilities and 3rd position has 13 possibilities (leaving people of 1st and 2nd position).
Total=2.3.13
Now, calculate the total outcome:
1st position has 15 possibilities, 2nd has 14 and 3rd has 13.
Total=15.14.13
Probability=desired outcome/total outcome
=2.3.13/15.14.13
=1/35
Therefore, probability of the given situation is 1/35.
