Erik decides to save money to buy a new computer. He starts with $100. He then adds a
constant amount each week.
● After 2 weeks, he has $140
● After 4 weeks, he has $180
Write an equation to represent the linear relationship between his total savings, S, in dollars, and the
number of weeks since he started saving, n. (Hint: use the equation Y 2 − Y 1 )

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

The Answer Is: E: -3,-4

A circle can be characterized by its center's location and its radius's length. The point that lies on the circle is represented by the equation (x−3)² + (y+4)² = 6² is (-3,-4).

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).

Hence, the point that lies on the circle is represented by the equation (x−3)² + (y+4)² = 6² is (-3,-4).

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

Step-by-step explanation:

Each one has 3 even and 3 odd numbers.

For the first one to be even there is a 3/6 probability, which reduces to 1/2.

The probability of the second one being even is also 1/2.

The probability of both being even would be 1/2 x 1/2 = 1/4 probability

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.

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.

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

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

Probability of obtaining a different result on each coin is [tex]\frac{1}{2}[/tex].

Probability means possibility. It is a branch of mathematics that deals with the occurrence of a random event. The value is expressed from zero to one.

Given

Olga flips 2 fair coins.

Probability of obtaining a different result on each coin

Total Number of favorable outcomes = {HH,TT,TH,HT} = 4

Number of favorable outcomes = {HT,TH} = 2

P(E) = [tex]\frac{Total Number of favorable outcomes }{Number of favorable outcomes}[/tex]

P(E) = [tex]\frac{2}{4}[/tex]

P(E) = [tex]\frac{1}{2}[/tex]
