B = boys g = girls
.................................
b + g = 195 b = 195 - g
<u>b</u> = <u>8</u>
g 7
Substitute b for 195 - g in the 2nd equation:
<u>b</u> = <u>8</u>
g 7
<u>195 - g</u> = <u>8</u>
g 7
Cross Multiply
8g = 7 . ( 195 - g )
8g = 1365 - 7g
8g + 7g = 1365
15g = 1365
g = <u>1365</u>
15
g = 91
Substitute g for 91 in one of the equations:
b + g = 195
b + 91 = 195
b = 195 - 91
b = 104
S = 104 boys.
Answer:
Is Jack's mom trying to give him diabetes?
Step-by-step explanation:
The total number of possibilities of drawing their names
is given by permutation.
4P4 = 24
The total possibility of drawing their names in
alphabetical is only 1.
Therefore the probability is:
P = 1 / 24
P = 0.0417
<span>Therefore there is about 4.17% chance that it will be in
alphabetical order</span>
16(5)+30
16x5=80
80+30=110
5(5)-12
5x5=25
25-12=13
110x13=1430
There are 1430 girls at the soccer tournament.
Hope this helps!
Answer:
50
Step-by-step explanation:
Let the event of people who believe that fuchsia is pink = A
Let the event of people who believe that fuchsia is purply = B
- Since 100 people were surveyed, the Universal Set =100
- 60 believe that fuchsia is ``kinda pink'', n(A)=60
- 27 believe it is both ``kinda pink,'' and also ``purply.'':
- 17 think that fuchsia is neither ``kinda pink'' nor ``purply.
We want to determine the number of those who believe that fuchsia is ``purply'', n(B).
In set theory, we have:
Therefore, the number of those who believe that fuchsia is ``purply'' is 50.
