Probability that Sara does not wins a raffle is [tex]\frac{3}{n+3}[/tex].
What is probability?Probability is simply how likely something is to happen. Whenever we're unsure about the outcome of an event, we can talk about the probabilities of certain outcomes—how likely they are.
Given
Probability that Sara wins a raffle is given by the expression
P(win) = [tex]\frac{n}{n+3}[/tex]
Probability that Sara does not wins a raffle is given by
P(does not win) = 1 - [tex]\frac{n}{n+3}[/tex]
= [tex]\frac{n+3}{n+3} -\frac{n}{n+3}[/tex]
= [tex]\frac{n+3-n}{n+3}[/tex]
= [tex]\frac{3}{n+3}[/tex]
Thus, probability that Sara does not wins a raffle is [tex]\frac{3}{n+3}[/tex].

Esteban finds 12 baseball cards on Monday and 24 more baseball cards on Tuesday. He gives some baseball cards to his sister, and now he has 13 baseball cards left. How many cards did he give to his sister?
Answer:
23 cards.
Step-by-step explanation:
After Monday, Esteban has 12 cards.
After Tuesday, Esteban has 12 + 24 = 36 cards.
He gave to his sister x cards.
36 - x = 13
36 = 13 + x

Factor f(x) into linear factors given that k is a zero of f(x).
f(x) = 4x3 + 23x² – 34x +7; k= 1
f(x) = (Factor completely.)
Step-by-step explanation:
step 1. if k is a zero then (x - 1) is a factor of 4x^3 + 23x^2 - 34x + 7.
step 2. we "can" use long division but synthetic division is easier!

Step-by-step explanation:
The circumfrence of a circle is as follows
2πr
For this question π=3.14
So we have
113.04=2πr
solve for r
r= 18
which means that diameter is 36
Just do the same thing with the other questions
18.84=2πr
r=3
31.4=2πr
r=5
37.68=2πr
r=6 which means that the diamater is 12

if mr.s rivas has 256 donust and she needs to give the same amount of dounts to her 5 freinds
Answer:
256/5=51.2
Step-by-step explanation:
Answer:
51 with a remainder of one, or 51.2
Step-by-step explanation:
She has 256 donuts and 5 friends. I assume this is for long division practice, so I will do long division.
5 | 256
Look at the first term. Does 5 go into 2? No. Bring down the next term.
5|256
25
Does 5 go into 25? Yes! How many times? 5. The first digit of our answer will be 5.
5|256 = 5
25
Now to get rid of the 25, we multiply the number we took for our answer by the divisor. 5x5 = 25. Subtract this from 25 and bring down the next (and last term).
5|256 = 5
25
-25
06
Does 5 go into 6? Yes. One time. Repeat what we did just now with this term now.
5|256 = 51
06
-5
1
Does 5 go into 1? No, it is smaller. Therefore we have a remainder of one donut.
If we are trying to divide ALL of the donuts equally, we will have to cut up the donut into 5 equal pieces. They would each be 1/5 of the donut, or 0.2.
So adding this, each friend would get 51 donuts, with an extra donut for Mrs Rivas, or each friend would get 51.2/51 and 1/5 donuts.

Answer:

The maximum value that the function reaches is 0, which occurs at x = 6.
What is a Quadratic equation?ax²+bx+c=0, with a not equal to 0 is a quadratic equation, which is a second-order polynomial equation in a single variable. It has at least one solution because it is a second-order polynomial equation, which is guaranteed by the algebraic fundamental theorem. The answer could be simple or complicated.
Since a blank grid is given, we can plot the graph of the quadratic function f(x) = x^2 - 5x - 24 using the given points:
X: 10 -8 6 4 2 4 6 8 10
f(x): -116 -12 0 -8 -20 -8 0 8 24
The graph of the quadratic function looks like a parabola opening upwards, with the vertex at the point (2, -20).
Based on the graph, we can make the following observations:
The function has a minimum value of -20, which occurs at x = 2.The function is symmetric about the vertical line that passes through the vertex (2, -20).The function intersects the x-axis at x = -3 and x = 8.The function intersects the y-axis at y = -24.Therefore, the statement that is NOT a true description of this quadratic function is:
"The function has a maximum value of 24, which occurs at x = 10."
This statement is not true because the function has a minimum value of -20 at x = 2, but it never reaches a maximum value of 24. The maximum value that the function reaches is 0, which occurs at x = 6.

Answer:

1000 at £1.10
1000 x 1.10 = £1100
35% of 1000 is given away
1000 - 35% = 1000 - 350 = 650 left
35% of £1100 = £385, subtract to get £715 pounds worth of pins left
650 are left, with 385 pounds lost
60% of 650 = 390 pins sold at £3 each
40% of 650 = 260 sold at £5 for 2
3 x 390 = £1170 made from the first lot
260/2 = 130 x 5 = £650 made from the second lot
£1170 + £650 = £1820 from sales
Sales - cost to make - losses (giveaways) = profit value
1820 - 1100 - 385 = 335 pounds of profit
To find the gross profit margin, we take the profit, and find what percentage of the production cost it is.
335 is about 30.45% of 1100
30.45%, which is 30.4% to 1 decimal place.

When dealing with graphs, involving points in between numbers, we have to carefully look at the x and y axis.
On the graph, the y-axis is going by 2s: 0, 2, 4, 6, 8, 10
On the x-axis, it's going by 1s: 0, 1, 2, 3, 4, 5, 6
Between 2 and 4 is 3
Between 4 and 6 is 5
Between 6 and 8 is 7
Between 8 and 10 is 9
Between 2 and 3 is 2.5
Between 3 and 4 is 3.5
Between 4 and 5 is 4.5
Between 5 and 6 is 5.5
Between 6 and 7 is 6.5
Between 7 and 8 is 8.5
Between 8 and 9 is 8.5
Between 9 and 10 is 9.5
Between 10 and 11 is 10.5
You get to see the pattern going on here...
On point E, we can see that the x-axis is 2.
Now on the y-axis, it is between 6 and 7. But if you look closely, you'll see that it's not on the line, that indicates 6.5.
So we find the median...
6, 6.1, 6.2, 6.3, 6.4, 6.5 6.2 and 6.3 are on the medium
[tex]\frac{6.2 + 6.3}{2}[/tex] = 6.25 Answer on E: (2, 6.25)
On point F, we can see that the x-axis is 3.
On the y-axis, it is between 8 and 10, which would be 9, BUT, look closely that it's also between 9 and 9.5.
The answer would be 9.5, but it is SLIGHTLY below 9.5, so I think it's 9.4
Answer on F: (3, 9.4)
On point G, the x-axis is between 3 and 4, so it's 3.5.
On the y-axis, we know it's going by 2s. We can see that G is between 10 and 12, so it would be 11. Because it is on that thin line, as you can see.
Answer on G: (3.5, 11)
