Answer:
The school will approximately raise 1500p.
Step-by-step explanation:
For part a) you're asked to complete the possibility space, this simply means to fill out in the provided chart with all possible outcomes for spinning the two spinners and adding the result of each.
You are already given two examples, particularly the case of landing a 2 and 1 (hence you get a 3) and landing a 8 and 3 (hence you get an 11). Just finish filling up the chart per the examples.
For part b) we must calculate the probability of having the outcome be 7. Assuming all sides of both spinners have the same probability of landing, we calculate this using classical probability so, as follows:
[tex]P(7)=\frac{n(7)}{n(all)}[/tex]
Where [tex]P(7)[/tex] represents the probability of getting seven, [tex]n(7)[/tex] the number of ways the two spinners can land in which they add up to 7, and [tex]n(all)[/tex] the number of all possible outcomes from spinning the two spinners. We are just doing the rule of "all favorable outcomes over all outcomes".
The total number of outcomes is 12, as there's only 12 ways the two spinners could land. The total number of ways we can get 7 is 3 (only by spinning 1 and 6, or 2 and 5, or 3 and 4). So, the probability of landing 7 is:
[tex]P(7)=\frac{n(7)}{n(all)}=\frac{3}{12}=\frac{1}{4}=.25[/tex]
So, there's a 25% chance of getting a 7 (hence of winning at this game). This means, if 120 play, approximately a 25% of them will win - so, approximately 30 contestants will win.
The school is charging 20p for playing, so the 120 participants are paying 2400p. However, because approximately 30 people will win, the school will have to buy 30 lollipops that cost 30p each - so, at the end the school will raise approximately 2400p (total earnings of tickets) - 900p (total losses from people winning) = 1500p (total money raised).

1 pipe can drain a swimming pool in 4 hours. A second pipe can drain the pool in 6 hours. How long will it take to drain the pool if both pipes are used?
3 hours
2 2/5 hours
10 hours
2 hours
Answers
Answer:
[tex]2 \dfrac25[/tex]
Step-by-step explanation:
The first pipe drains 1/4 of the pool every hour, and the second pipe drains 1/6 of the pool every hour. Combined, they drain [tex]\dfrac14 + \dfrac16 = \dfrac{5}{12}[/tex] of the pool per hour. Therefore, it will take 12/5 hours, or 2 2/5 hours.
(brainliest pls ty)
Both pipe are together then they take 6 hour to fill the pool.
In 1 hour they fill the pool is 110 hours
What is the explanation?In 1 hour pipe A can fill the pool = x/1
In 1 hour pipe B can fill the pool= y/1
so
4 hours=x/4
6 hours=y/6
If both pipe are together then they take 6 hour to fill the pool.
If the are together then in 1 hour they fill the pool.
x/1 + y/1 = 6/1+4/1= −−−−(1)
=10 hours
Example:A swimming pool may be filled using two pipes in 12 hours. Only half of the pool can be filled if the larger pipe is utilized for 4 hours and the smaller pipe for 9 hours.
10,000 divided by 240 minutes, or 4 hours, yields approximately 41.6. With the drain blocked, your pool would therefore fill at a rate of about 41 gallons per minute.

Step-by-step explanation:
the perimeter o DOG is 33. If DO = 10 and DG = 12, find the larger of the two segments into which the third side is divided by the angle bisector of ODG
Answers
Answer:
The size of the larger of the two segments = 6
Step-by-step explanation:
Attached below is the triangle ( DOG )
perimeter of Triangle = 33
DO = 10
DG = 12
OG = x
formula for perimeter = DO + DG + OG = 33
= 10 + 12 + OG = 33
hence: OG = 33 - ( 10 + 12 ) = 33 - 22 = 11
third side ( x ) = 11
Finally determine the length of the larger of the two segments of side ( OG)
from the diagram below
[tex]\frac{y'}{x'} = \frac{12}{10}[/tex] -------------------- ( 1 )
where x' = 11 - y'
hence equation 1 becomes
10y' = 12x'
10y' = 12 ( 11 - y' )
10y' = 132 - 12y'
22y' = 132
∴ y' = 132 / 22 = 6
hence x' = 5

difference in grams?
Answers
Answer:
The watermelon weighs 2,500 grams more than the cantaloupe.
Step-by-step explanation:
Giving the following information:
Watermelon= 5kg
Cantaloupe= 2,500 grams
We know that 1 kilogram equals 1,000 grams.
First, we need to determine the weight of the watermelon in grams.
Watermelon= 5*1,000= 5,000 grams
Now, the difference:
Difference= 5,000 - 2,500
Difference= 2,500 grams
The watermelon weighs 2,500 grams more than the cantaloupe.

Hillary works at a video store. she earns $8.50 per hour plus 12% commission on all the weekly sales she makes. If she works 24 hours in a week, which expression best describes her sales (x) if she earns at least $324 during that week
Answers
Answer: See explanation
Step-by-step explanation:
Let her sales be represented by x.
Based on the information given in the question, the equation to calculate her sales goes thus:
(8.50 × 24) + (12% × x) ≥ 324
204 + (0.12 × x) ≥ 324
204 + 0.12x ≥ 324
0.12x ≥ 324 - 204
0.12x ≥ 120
x ≥ 120/0.12
x ≥ 1000
Her sales is at least $1000
