The odds against Jim beating a friend at golf are 7:2. Find the probability that Jim will win.
Answer:
if the probability is 7:2, then there are 9 possible outcomes
so do 7 divided by 9 and Jim has a 77% chance of winning
Probability helps us to know the chances of an event occurring. The probability that Jim will win is 22.22%.
What is Probability?Probability helps us to know the chances of an event occurring.
[tex]\rm Probability=\dfrac{Desired\ Outcomes}{Total\ Number\ of\ outcomes\ possible}[/tex]
Given that the odds against Jim beating a friend at golf are 7:2. Therefore, the ratio of the number of games that Jim's friend wins to the number of games that Jim wins is,
Number of games Jim's friend wins/ Number of games Jim wins = 7/2
Now, the total of games they both play will be 9, which is the sum of 7 and 2. Therefore, the probability that Jim will win is,
Probability (Jim wins) = Number of games Jim wins / Total number of games
= 2 / 9
= 22.22%
Hence, the probability that Jim will win is 22.22%.

w(x) = x2 + 1; Find w(x + 3)
Given the function w:
[tex] \displaystyle \large{w(x) = {x}^{2} + 1 }[/tex]
Since we want to find w(x+3), the input would be x+3.
Substitute x = x+3 in.
[tex] \displaystyle \large{w(x + 3) = {(x + 3)}^{2} + 1 }[/tex]
Alternate Solution
The answer above works if you want it in vertex form. For this alternate solution, I will convert the function in standard form.
As we know:
[tex] \displaystyle \large{ {(x + y)}^{2} = {x}^{2} + 2xy + {y}^{2} }[/tex]
Therefore:
[tex] \displaystyle \large{ {(x + 3)}^{2} = {x}^{2} + 2(x)(3) + {3}^{2} } \\ \displaystyle \large{ {(x + 3)}^{2} = {x}^{2} + 6x+ 9}[/tex]
Now for function w:
[tex] \displaystyle \large{w(x + 3) = {x}^{2} + 6x + 9+ 1 } \\ \displaystyle \large{w(x + 3) = {x}^{2} + 6x + 10}[/tex]
Hence:
The answer is w(x+3) = (x+3)^2+1 for vertex formOR w(x+3) = x^2+6x+102 (1 - x) + 5 > 3 (2 x 1)

a number, y, less than 50 is 82
Answer:
y = -32
Step-by-step explanation:
I'm not completely sure of what you're asking but less than means you subtract the number from 50.
So...
50 - y = 82
Subtract 50 from both sides
-y = 32
Divide both sides by -1
y = -32
Question 1 options:
You want to go out shopping to buy 2 dozen eggs at $10, 3 loaves of bread each at $5, and 5 bottles of drinks, each at $8. How much money do you need
Answer:
Step-by-step explanation:
24 eggs = 10 dollars
3 loafs of bread for 5 dollars each x 3 = amount together so 15
5x8=40 dollars for all drinks, so
10+15+40
Hey there! I'm happy to help!
First, we have our eggs, which cost $10
10
Then, we have our 3 loaves of bread. Each one costs $5. 5×3 is 15, so we will add this to our total.
10+15
And then we have our 5 drinks, each costing $8. 8×5 is 40, so we will add 40 to our total.
10+15+40=65
So, we need $65 dollars to go out shopping.

What is the measure of angle C?
Enter your answer in the box.
Answer:
The measure of angle C is 92°
Step-by-step explanation:
In a quadrilateral opposite angles are supplementary (Angles add up to 180°)
So since we have two opposite angles already set up the equation:
(x+24)+(x+10) = 180
Combine like terms - x+x+24+10 = 180 → 2x+34 = 180
Cancel out the constant to solve for x: 2x+34-34 = 180-34
Divide both sides by 2 so x is isolated: 2x/2=146/2
Solve: x=73
Now that we know x = 73 we can find angle C by setting up the equation:
Let C represent the unknown angle of ∠C
73+15+C=180
Combine like terms: 88+C=180
Isolate C: 88-88+y=180-88
Solve for C: C=92

Mathewson middle school band is selling t-shirts to raise money for new uniform they need to raise $1260. They are selling t-shirt for $12 each. There is 6 profit for each shirt sold . So far they have sold 85 t - shirt how many more t-shirts do they need to sell to raise the $1260?
Step-by-step explanation:
Ok they need to make $1,260.
Each t-shirt sells for $12 but they only make half that amount $6
So far 85 t-shirts have been sold
85 * 12 = 1,020
Ok but remember its half that amount-
1,020 / 2 = 510
So far they have $510 raised.
1260 - 510 = 750
They still need to raise $750.
If we divide $750 / 6 = 125
So that's our answer, now if we wanna verify-
125 * 12 = 1500
1500 / 2 = 750
So after revising, we are left with the answer 125, Mathewson middle school must sell 125 more t-shirts to make the desired amount.
Hope this helps! :)

find the value of x
a. 10
b. 6
c. 35
d. 21
explain please
Answer:
x = 10
Step-by-step explanation:
Assuming that the triangles are similar we can use ratios to solve for x.
x / 6 = 35 / 21
Using cross products we acquire,
35 * 6 = 210
21 * x = 21x
21x = 210
Divide both sides by 21
21x/21=x
210/21=10
x = 10

Graph the data in the table. Which kind of function best models the data? Write an equation to model the data.
A. quadratic; y = –2.5x2
B. linear; y = 2.5x
C. exponential; y = 2.5x
D. quadratic; y = 2.5x2
Answer:
D. quadratic; y = 2.5x2
Step-by-step explanation:
Answer:
A. quadratic; y = 2.5x2
Step-by-step explanation:
Answer:
Option (1)
Step-by-step explanation:
x -2 -1 0 1 2
y 10 2.5 0 2.5 3.0
Ist difference,
= -2.5
= 2.5
= 7.5
2nd difference,
= 5
= 5
= 5
Since 2nd difference is common, given table represents a quadratic equation.
Let the equation is,
y = ax²+ bx + c
For a point (0, 0) passing through the quadratic equation,
0 = c
Therefore, quadratic equation is y = ax² + bx
Since ordered pair (-1, 2.5) passes through the graph of the function,
2.5 = a(-1)² + b(-1)
a - b = 2.5 ------(1)
For another point (1, 2.5)
2.5 = a(1)² + b(1)
a + b = 2.5 ------(2)
By adding equations (1) and (2),
2a = 5
a = 2.5
and from equation (2)→ y = 0
Therefore, equation of the quadratic function given in the table is y = 2.5x²
Option (1) is the answer.
