The expected value of the defective skateboard will be 4/25. Then the correct option is B.
What is probability distribution?Probability distribution of a random variable is the collection of value and its probability pair for values of that considered random variable.
It might be a function, a table, etc.
The table is shown below.
Then the expected value of the defected skateboard will be
p = 0 x 9/10 + 1 x 1/20 + 2 x 1/25 + 3 x 1/100
p = 1/20 + 2/25 + 3/100
p = 5/100 + 8/100 + 3/100
p = 16/100
p = 4/25

Answer:
[tex] \frac{5}{12} [/tex]
Hope it helps............
HELP ME PLEASEEEEE
Answer:
x = 4
Step-by-step explanation:
x(x + 8) = 48
x² + 8x = 48
x² + 8x - 48 = 0
times into -48
add into 8
(x - 4)(x + 12) = 0
x - 4 = 0
x = 4
or
x + 12 = 0
x = -12
A length cannot be a negative number therefore x = 4

Enter the solution (x, y) to the system of equations shown.
Answer:
(2, 5 )
Step-by-step explanation:
y = 2x + 1 → (1)
3y = 4x + 7 → (2)
substitute y = 2x + 1 into (2)
3(2x + 1) = 4x + 7 ← distribute parenthesis on left side
6x + 3 = 4x + 7 ( subtract 4x from both sides )
2x + 3 = 7 ( subtract 3 from both sides )
2x = 4 ( divide both sides by 2 )
x = 2
substitute x = 2 into (1) for corresponding value of y
y = 2(2) + 1 = 4 + 1 = 5
solution is (2, 5 )

Determine the following probabilites based on a standard deck of cards
1) Pblack or heart)=
2) Pired or 10) =
3) P(Q or 6) =
4) P(5 or club) =
5) P(picture card or 4) =
6) P(black 9 or red) =
There are 52 cards total.
Hearts and diamonds are red.
Clubs and spades are black
LQ and K are called picture cards.
Answer & Step-by-step explanations:
I assume they want probability as a decimal as opposed to a fraction. I will do two questions for you, apply the same logic to all the rest.
P(Black or heart):
There are 26 black cards in a deck, and 13 (red) hearts.
26 + 13 out of 52 cards.
39 / 52 as a decimal is 0.75
P(Black or heart) = 0.75 or 75%
If wanted as a fraction, simplify your fraction down
39/52 has a common factor of 13, divide both numbers by 13
P(Black or heart) = 3/4
P(Red or 10):
There are 26 red cards and four 10's in a deck. Two of these 10's are red, so we will not double count them.
26 + 2 out of 52 cards.
28 / 52 as a decimal is about 0.54 or 54%
P(Red or 10) = 0.54 or 54%
If wanted as a fraction, simplify your fraction down
28/52 has a common factor of 4, divide both numbers by 4
P(Red or 10) = 7/13

Ruben had a 18.4 m length of rope. He used 6.4 m of the rope
to make a rope ladder for a playground. He cut the remaining
rope into 2 equal pieces to make tire swings. How long is each
tire swing rope?
Answer:
3.2m
Step-by-step explanation:
First you do 18.4-6.4m, to get the amount of rope left after Ruben has used some to make that rope ladder. Then you get your answer, which in this case is 6.4, and divide it by 2. This way we get the length of one of the two equal lengths. After this we get 3.2m, which is the length of each tire swing rope!
Answer:
6 m.
Step-by-step explanation:
Remaining length = 18.4 - 6.4 = 12 m
So the length of each swing rope
= 12/2
= 6 m.

Write a quadratic equation that has only one real-number solution
The equation that has only one real number solution is
4a²x²+4abx+ b² = 0 and the solution is x = -b/2a where a, b, and c are real values.
What is a quadratic equation?Any equation of the form [tex]\rm ax^2+bx+c=0[/tex] Where x is variable and a, b, and c are any real numbers where a ≠ 0 is called a quadratic equation.
As we know, the formula for the roots of the quadratic equation is given by:
[tex]\rm x = \dfrac{-b \pm\sqrt{b^2-4ac}}{2a}[/tex]
If the quadratic equation has only one solution, then
[tex]\rm b^2 - 4ac = 0[/tex] or
[tex]\rm b^2 = 4ac[/tex]
[tex]\rm x = \dfrac{-b}{2a}[/tex]
2ax = - b
(2ax+b) = 0
(2ax+b)² = 0 (square on both sides)
[tex]\rm 4a^2x^2 + 4abx+ b^2 = 0[/tex]
Thus, the equation that has only one real number solution is
4a²x²+4abx+ b² = 0 and the solution is x = -b/2a where a, b, and c are real values.

Is the point (2,-11) on the circle with radius 5 and center (2,13)?
Answer:
No
Step-by-step explanation:
Identify the equation for the circle
[tex](x-h)^2+(y-k)^2=r^2\\(x-2)^2+(y-13)^2=5^2\\(x-2)^2+(y-13)^2=25[/tex]
Check if (2,-11) is a point on the circle
[tex](x-2)^2+(y-13)^2=25\\(2-2)^2+(-11-13)^2=25\\0^2+(-24)^2=25\\576\neq25[/tex]
Since both sides of the equation are not equal to each other, then (2,-11) is not a point on the circle.
How would logx (49) = x look like in exponential form
I'm assuming the given log equation is [tex]\log_{\text{x}}(49) = \text{x}[/tex]
If so, then the exponential form is [tex]\text{x}^{\text{x}} = 49[/tex]
This is because the general form [tex]\log_{\text{b}}(\text{x}) = \text{y}[/tex] transforms into [tex]\text{y} = \text{b}^{\text{x}}[/tex]
For both equations, the 'b' is the base.

Jim's got profit percentage is 46.67%
What is profit percentage?Profit percentage is refer to "the amount of profit that has been incurred in terms of percentage".
According to the question,
Jim buys a wardrobe for £30 which is cost price of wardrobe and he sells £44.
In order to find profit percentage we have to use formula.
Profit percentage = [tex]\frac{selling price - cost price }{cost price}[/tex] × 100
= [tex]\frac{(44-30)}{30}[/tex] × 100
= [tex]\frac{14}{30}[/tex] × 100
= 46.6667% ≈ 47%
Hence, Jim's got profit percentage is 46.67%.
