Justin ,cam and Ben are playing a board game where exactly one player will win .Ben estimates that Justin has a 20% chance of winning each game and that cam has a 50% chance of winning each game?
Answers
Question :
Justin, Cam, and Ben are playing a board game where exactly one player will win. Ben estimates that Justin has a 20%, percent chance of winning each game and that Cam has a 50%, percent chance of winning each game. What is the probability that Ben will win the board game?
Answer: 30%
Step-by-step explanation:
Given the following :
Justin's chance of winning each game = 20%
Cam's chance of winning each game = 50%
Therefore, probability of :
Justin winning = 20/100 = 0.2
Cam winning = 50/100 = 0.5
Overall probability = 100% = 1
Therefore,
P(Justin winning) + P(Cam winning) + P(Ben winning) = 1
0.2 + 0.5 + P(Ben winning) = 1
P(Ben winning) = 1 - 0.7
P(Ben winning) = 0.3
0.3 = 30%

The tree increased in height each month until the time period between month 9 and month 11
The statement that can be supported by the given information is, "The height of the tree increased in height each month until the time period between month 9 and month 11".
Given a table that shows the height of the tree that Margo planted over an 11-month period.
When the months are 1, 3, 5, 7, 9, and 11, the height of the tree is 1.4, 1.5, 2.1, 2.7, 3, and 1.8 respectively.
It is clear that the height of the tree increases during the months from 1 to 9.
During the time period between 9 and 11, the height of the tree decreases to 1.8 from 3.
So, the height of the tree increased in height each month until the time period between month 9 and month 11.

26 fifth graders are learning to make balloon animals. There are 580 balloons to share equally among the students. How many balloons will be left over?
Answers
Answer: There will be 8 balloons left over.
Step-by-step explanation: A total of 580 balloons to be distributed equally among 26 students means 580 ÷ 26.
The division is not exact, since 580 are not divisible by 26, it will result in a rest, so
580 ÷ 26 = 22 and has rest 8
Therefore, there will be 8 balloons left over.

Sarah burned 280 calories running 20 minutes. The next day, Sarah burned 490 calories running for 35 minutes. Let c represent the number of calories. Let t represent time, in minutes, spent running. Which equation represents this relationship?
Answers
Answer:
c = 14 * t
Step-by-step explanation:
we have to calculate the average to make the equation, the first thing is to calculate the calories burned per minute in the two days:
the first day:
280/20 = 14
second day:
490/35 = 14
that is, how it does not change from day to day, the average is 14 calories per minute, therefore, the equation would be:
c = 14 * t
The equation represents this relationship is [tex]c = 14 \times t[/tex]
Calculation of an equation:Since Sarah burned 280 calories running 20 minutes. The next day, Sarah burned 490 calories running for 35 minutes. Let c represent the number of calories. Let t represent time, in minutes, spent running.
So, here we need to determine the burned per minute for 2 days
So,
the first day
[tex]= 280\div 20[/tex]
= 14
And, the second day:
[tex]= 490\div 35[/tex]
= 14
Therefore, The equation represents this relationship is [tex]c = 14 \times t[/tex]

What is the area of the square adjacent to the third side of the triangle?
If known could u answer the other as well ?
Answers
Answer:
85 units^2 = Area of Blue Square
and
x = 5 units
Step-by-step explanation:
To do this we use the Pythagorean theorem (a^2 + b^2 = c^2). a and b represent the legs of the triangle whereas c represents the longest side of the triangle, or the hypotenuse.
Since we know the area of a square is the side length multiplied by itself (or the side length squared), [tex]\sqrt{35}[/tex] is the side length of the pink square and [tex]\sqrt{50}[/tex] is the side length of the green square.
That means a = [tex]\sqrt{35}[/tex] and b = [tex]\sqrt{50}[/tex] , so...
[tex](\sqrt{35} )^{2} + (\sqrt{50})^{2} = c^{2}[/tex]
35 + 50 = c^2
85 = c^2
[tex]\sqrt{85} = c[/tex]
Now we need to square the square root of 85 to find the area of the blue square.
[tex](\sqrt{85})^{2} = Area of blue square[/tex]
85 units^2 = Area of Blue Square
To solve the other question we use the same formula again.
[tex]x^2 + 12^2 = 13^2\\x^2 +144 = 169\\-144\\x^2 = 25\\x=\sqrt{25} \\x=5[/tex]

The sum of 3 consecutive odd integers is 411. State the values of the integers.
Answers
Answer:
135, 137, 139
Step-by-step explanation: My bad, I did not see that it said consecutive odd integers
x+x+2+x+4=411
3x+6=411
3x=405
x=135
x+2+137
x+4=139
Represent 3 consecutive odd integers as follows.
X ⇒ first odd integer
X + 2 ⇒ second odd integer
X + 4 ⇒ third odd integer
Since their sum in this problem is 411, x + (x + 2) + (x + 4) = 411.
Now combine like terms to get 3x + 6 = 411.
No subtract 6 from both sides to get 3x = 405.
Now divide both sides by 3 and x = 135.
So x + 2 would be 137 and x + 4 would be 139.
So our consecutive odd integers are 135, 137, and 139.
Rewrite the function by completing the square
F(x)=x^2+6x-78
F(x)=(x+?)^2+?
Answers
Answer:
F(x) = (x + 3)^2 -87
Step-by-step explanation:
Here, we want to rewrite the function by completing the square.
Firstly, we move the c term(-78) to the right hand side of the equation and that becomes
x^2 + 6x = 78
Then, we can complete the square on the right hand side here, to be
Let’s add 9 to both sides
That would be;
x^2 + 6x + 9 = 78 + 9
x^2 + 6x + 9 = 87
(x+3)^2 = 87
or simply
(x+3)^2 -87 = 0
So our F(x) becomes
F(x) = (x + 3)^2 -87

The expression after completing the square is:

Thea enters a positive integer into her calculator, then squares it, then presses the $\textcolor{blue}{\bf\circledast}$ key, then squares the result, then presses the $\textcolor{blue}{\bf\circledast}$ key again.

The final number is $243$.
As previously the $\textcolor{blue}{\bf\circledast}$ key was pressed,
the number before $243$ must be $324$.
As previously the number was squared, so the number before $324$ must be $18$.

A bicycle manufacturing company knows that the equation R=-2.5p?+ 500 p models
the relationship between the price (p) and the revenue (R) for one of its product lines.
What is the maximum revenue possible?
$
Answers
Answer:
The maximum revenue is $25,000
Step-by-step explanation:
The model equation is;
R = -2.5p^2 + 500p
To find the maximum value, we differentiate this and set result = 0
The first differential of this model equation is -5p + 500
we set this to zero to get the maximum price
5p = 500
p= 500/5
p = 100
Now to get the maximum revenue, we simply substitute the value of the maximum price
That would be -2.5(100)^2 + 500(100)
= -2.5(10,000) + 50,000
= 25,000 + 50,000
= 25,000

Answers
Answer:
[tex]m\widehat {EB}[/tex] = 96°
Step-by-step explanation:
From the figure attached,
m∠ECB = 25°
[tex]m\widehat {EB}={(4x+16)}[/tex] degrees
[tex]m\widehat{DB}=(7x+6)[/tex] degrees
From the theorem of secants intersecting outside the circle,
m∠ECB = [tex]\frac{1}{2}[m\widehat {DB}-m\widehat{EB}][/tex]
25° = [tex]\frac{1}{2}[(7x + 6) - (4x + 16)][/tex]
25° = [tex]\frac{1}{2}(3x-10)[/tex]
50 = 3x - 10
3x = 60
x = [tex]\frac{60}{3}[/tex]
x = 20
[tex]m\widehat {EB}[/tex] = (4 × 20 + 16)°

HEELPPP how do I solve this equation please do it step by step
Answers
Answer:
x = -24/7 or x = -3 3/7
Step-by-step explanation:
In this equation, the first thing we will do is to get rid of the denominators -- they complicate everything. So, we can multiply the entire equation by 10, since 10 is the lowest common multiple of 5 and 2, which are the denominators.
Then, the equation will look like this:
2(4x-2) + 5(1) = 5(3x+7) - 10(1)
Notice that the denominators will no longer exist.
Now, distribute on both sides of the equation.
The equation will look like this now:
8x - 4 + 5 = 15x + 35 - 10
Then, we must combine like terms. We want to isolate the variable x on one side of the equation. Let's isolate it on the right side. So, subtract 8x from both sides. The equation will look like this now: - 4 + 5 = 7x + 35 - 10
Now that x is on one side, let's move all the other terms to the left side. Subtract 25 from both sides (35 - 10 = 25 on the right side, get rid of it by subtracting 25). The equation now looks like this: - 4 + 5 - 25 = 7x
Finally, combine all on the left side.
Final equation: -24 = 7x
Now, we know 7x = -24. We want to solve for the value of x. So, divide both sides by 7.
x = -24/7 or x = -3 3/7
