Answer:
-2
Step-by-step explanation:
The school can expect to raise 1500p for charity.
<u>Explanation:</u>
(a)
The possibility space is solved in the image attached.
(b)
20p for each player
30p for lollipop
Number of people = 120
Charity amount = ?
Out of 12 outcomes, the probability of getting 7 is 3
So, probability of getting 7 for 120 people = 
= 30
Money earned from the players = 20p X 120
= 2400p
Cost of 30 lollipops = 30p X 30
= 900p
Money received for charity = 2400p - 900p
= 1500p
Therefore, the school can expect to raise 1500p for charity.
Answer:
<u><em>y = -5x + 10</em></u>
Step-by-step explanation:
<em>We know the slope-intercept form is :-</em>
<em>y = mx + b</em>
<em></em>
<em>Now, convert it into that form.</em>
<em>25x + 5y = 50</em>
<em>5y = -25x + 50</em>
<u><em>y = -5x + 10</em></u>
Answer:
A. f(x)=x^2+x+0.25
Step-by-step explanation:
If x represents Lindsey's distance at 2:00 PM, then 2x represents Kara's distance at 2:00 PM because she walked twice as far as Lindsey. Then adding on the values we got for 2:30 PM, we get that Kara walked a distance of 2x+1 and Lindsey walked a distance of x+0.5 at the time of 2:30 PM. Now, we know that they have formed a right triangle because we are given the directions they walked in; east and north. This allows us to use a formula for the area of a right triangle: 1/2(L x W). Plugging in our values, we get...
1/2(2x+1)(x+0.5)
which simplifies to...
1/2(2x^2+2x+0.5)
which further simplifies to...
x^2+x+0.25
which is our answer.
Answer:
When multiplying fractions, multiply the top number by the top number, and the bottom number by the bottom number.
So we have: (9x2)/(10x5).
This simplifies to: 18/50, or 9/25.
Let me know if this helps!
