A cell phone plan costs $200 to start. Then there is a $50 charge each month.Is there a proportional relationship between time and the cost of the cell phone plan? Explain your answer.
Answer:
No because there is a initial cost of $200.
Answer:
see below
Step-by-step explanation:
The equation is
y = 200+50x
This is not a proportional relationship because it does not go through the origin
If x=0, y does not equal 0

B.
0.43
C.
0.51
D.
0.67
E.
0.92
Answer:
lol don't listen to him/her, they're wrong.
it's 0.92, for plato. i got it right
Step-by-step explanation:
The probability that an athlete uses steroids, given that he tests positive is 0.92. Therefore, option E is the correct answer.
What is the probability?Probability can be defined as the ratio of the number of favourable outcomes to the total number of outcomes of an event.
Let the total number of athletes be 'x'. and let 'P' denotes the probability.
Let A shows the event that a athlete test positive for steroids.
Let B shows the event that athlete use steroids as given in the question 12% of the athletes test positive for steroids=0.12 x.
P(A)=0.12 x
also we know that 11% of the athletes test positive for steroids actually use steroids=0.11 x.
P(A∩B)=0.11 x
Now we are asked to find the probability that an athlete uses steroids, given that he test positive that is we have to find
Now, P(B|A)=P(A∩B)/P(A)
= 0.11x/0.12x
= 0.92
Therefore, option E is the correct answer.

A group of 6 friends of varying ages meets at a coffee shop and sits in a circle. What is the probability that the
youngest member of the group sits in the seat closest to the door?
Answer:
[tex]100.00 \div 6 [/tex]
The probability that the youngest member of the group sits in the seat closest to the door 1 / 6
Given that, a group of 6 friends of varying ages meets at a coffee shop and sits in a circle, we need to find the probability that the youngest member of the group sits in the seat closest to the door,
So, the probability = favorable outcomes / total outcomes
Here, the favorable outcome = 1
The total outcomes = 1, 2, 3, 4, 5, 6 = 6
So, the probability = 1/6 = 1/2
Hence, the probability that the youngest member of the group sits in the seat closest to the door 1 / 6

Answer:
x = -3/2 x =0
Step-by-step explanation:
(2x+3) ^2 - 6x-9 = 0
Factor out -3 from the last 2 terms
(2x+3) ^2 - 3( 2x+3) = 0
Let m = 2x+3
m^2 - 3m = 0
Factor out m
m(m-3) =0
Using the zero product property
m=0 m-3 =0
m=0 m=3
Substitute 2x+3 back in for m since we are looking for the value of x
2x+3 =0 2x+3 =3
2x +3-3=0-3 2x+3-3=3-3
2x = -3 2x=0
x = -3/2 x =0

f(x)=4x+1 and g(x)=x^2-5find(f-g)(x)
Answer:
-x²+4x +6Step-by-step explanation:
Given f(x)=4x+1 and g(x)=x²-5
(f-g)(x) is derived by taking the difference of both functions
(f-g)(x) = f(x)-g(x)
(f-g)(x) = 4x+1 - (x²-5)
(f-g)(x) = 4x+1-x²+5
(f-g)(x) = -x²+4x +6

What is an equation of a circle?A circle can be characterized by its center's location and its radius's length.
Let the center of the considered circle be at (h,k) coordinate.
Let the radius of the circle be 'r' units.
Then, the equation of that circle would be:
(x-h)² + (y-k)² = r²
If a circle is graphed with the equation on the graph, also, all the points given are graphed, then it can be observed that the only point that lies on the circle is (-3,-4).

A 26-foot ladder is placed against a house and reaches the 24-foot roof. What is the distance between the base of the ladder and the base of the house if the ground meets the house at a right angle?
Answer:
The distance from the base of the ladder to the base of the house is 10ft
Step-by-step explanation:
From the question, we can gather that the ladder makes a right angle shape with the wall of the house.
The length of this ladder which represents the hypotenuse of the right angled triangle is 26ft while the height of the house to the roof is 24ft
To calculate the distance between the base of the ladder and the base of the house, we shall be employing the use of Pythagoras’ theorem which states that the square of the hypotenuse equals the sum of the square of the 2 other sides
We have established that the hypotenuse is the length of the ladder which is 26ft
Let the distance we want to calculate be d
26^2 = 24^2 + d^2
d^2 = 26^2 -24^2
d^2 = 676 - 576
d^2 = 100
d = square root of 100
d = 10ft
Answer:
10
Step-by-step explanation:
24^2 = 576
26^2 = 676
676 - 576 = 100
the square root of 100 is 10 so the answer is 10
