3. Diya's chances of winning the game are
only 40%.
Express this as a probability fraction.
Answer:
2/5
Step-by-step explanation:
40% as a fraction is 4/10, when this fraction is simplified, it ends up as 2/5.
The probability of the event that Diya's chance of wining the game is 0.4 or 2/5.
What is probability of an event?The probability of an event is the chance of happening that particular event.
Let, Diya can play a game 100 times.
Therefore, the number of times she can win the game is 40.
Let, D = the event that Diya is participating in the game.
Therefore, the probability that Diya will win the game is
[tex]= P(D)\\= \frac{40}{100}\\ = \frac{2}{5}\\ = 0.4[/tex]

If f(x) = 3x - 4 and g(x)=x?, find the value of
f(3) - g(2)
A) 4
B) 9
C) 1
D) 7
Answer:
C) 1
Step-by-step explanation:
f(x) = 3x - 4 when x = 3
= 3(3) - 4
= 9 - 4
= 5
g(x) = x^2 when x = 2
= 4
Subtract both values.

Does the following represent a function?
f = [ (3, -1), (2, 5), (4, -6), (3, 4), (5, -8) ]
Answer:
Not a function
Since x= produces y- -1 and y=-4, the relation (3,-1),(2,5),(4,-6),(3,4),(5,-8) is not a function.

We understand this to be two separate problems.
-3/9 +(-2 9/10) = -(3/9 +2 9/10)

Points A, B, and C are collinear and B lies between A and C. If AC = 48, AB = 2x + 2, and BC = 3x + 6, what is BC?
BC=
On a number line, suppose point E has a coordinate of −3,and EG=8.What are the possible coordinates of point G?
The possible coordinates for G are?
Please help!
Answer:
30
Step-by-step explanation:
AC = AB + BC
48 = 2x + 2 + 3x + 6
48 = 5x + 8
48 - 8 = 5x
40 = 5x
40/5 = x
8 = x
Finding BC
BC = 3x + 6
BC = 3(8) + 6
BC = 24 + 6
BC = 30
#2
Coordinate = -3 + 8 = 5
Answer:
BC = 305Step-by-step explanation:
We know that adding AB and BC will give us AC so we can create an equation and solve for x.
2x + 2 + 3x + 6 = 48
~Combine like terms
5x + 8 = 48
~Subtract 8 to both sides
5x = 40
~Divide 5 to both sides
x = 8
Now that we know the value of x, we can solve for BC.
= 3(8) + 6
= 24 + 6
= 30
I would assume 8 is the length of EG so we would add that value to -3 and find where that would be at on the number.
-3 + 8 = 5

Find the area of the triangle
9514 1404 393
Answer:
D. 72sin(α)cos(α)
Step-by-step explanation:
Given two sides and the angle between, the area of a triangle can be found from the formula ...
Area = (1/2)ab·sin(C)
Here, that translates to ...
Area = (1/2)(12)(y)sin(α)
Using the trig relation ...
Cos = Adjacent/Hypotenuse
we can find y:
cos(α) = y/12
y = 12·cos(α)
__
Substituting this into the area calculation above, we have ...
Area = (1/2)(12)(12·cos(α))sin(α)
Area = 72sin(α)cos(α)
please help that’s all i just need to make i’m correct it due tomorrow early so please
Find the area of this figure. round your answer to the nearest hundredth.
Answer:
The area of the figure is 49.12ft² (nearest hundredth)
Step-by-step explanation:
The area of the figure is the sum of the areas of the right triangle and semi circle that make up the figure.
Note that the radius of a circle is twice its diameter
That means, the radius of the semi-circle is 4 feet
Area of the triangle = 1/2 x Base X Height = 1/2 x 6 ft x 8 ft =24 ft²
Area of the semi circle = 1/2 πr² = 1/2 x 3.14 x 4² = 25.12 ft²
Hence, the area of the figure is:
24 ft² + 25.12 ft² = 49.12 ft²

Hello so can someone help me with this problem. My teacher doesn't explain it very well </3
[tex] t= 50 + \frac{n - 4}{4} [/tex]
switch sides
[tex]50 + \frac{n - 4}{4} = t[/tex]
subtract 50 from both sides
[tex]50 + \frac{n - 4}{4} - 50 = t - 50[/tex]
simplify
[tex] \frac{n - 4}{4} = t - 50[/tex]
simplify
[tex] \frac{n - 4}{4} = t - 50[/tex]
multiply both sides by 4
[tex]4 \frac{(n - 4)}{4} = 4t - 4 \times 50[/tex]
simplify
[tex]n - 4 = 4t - 200[/tex]
add 4 both sides
[tex]n - 4 + 4 = 4t - 200 + 4[/tex]
[tex] n = 4t - 196[/tex]

P, Q, V, and K are collinear with V between K and P, and Q between V and K. If VP = 14x + 4, PK = x + 630, VQ = 17x + 6, and KQ = 11x + 5, solve for VP.
9514 1404 393
Answer:
VP = 214
Step-by-step explanation:
The order of points on the line is KQVP. The whole is the sum of the parts, so we have ...
KQ +QV +VP = KP
(11x +5) +(17x +6) +(14x +4) = x +630
42x +15 = x +630 . . . . . . . . . . . . . . . . . collect terms
41x = 615 . . . . . . . . . . . subtract x+15
x = 15 . . . . . . . . . . divide by 41
Then the measure of VP is ...
VP = 14x +4 = 14·15 +4 = 210 +4
VP = 214
