Answer:
The first statement “The lines have different slopes” That’s the only true statement. In the equation y=2x-3 it tells us that the slope is 2, but in the other equation, it has no slope.

Reasoning behind the other statements:
It can’t be statement 2 because there is a solution. And the solution is (0,-3)

It can’t be statement 3 either because both equations DONT have the same slope, if they did, the graphs would be the same and will have infinite solutions. Also it says “different y-Intercepts” BUT they do have the same y- intercepts, and the y-intercept is -3

Now finally, the last statement isn’t true because like I mentioned earlier, the solution is (0,-3) NOT (-3,-9)

What is 12% on $3,200 in sales?
Karolina [17]

Answer:

The easiest way of calculating discount is, in this case, to multiply the normal price $3200 by 12 then divide it by one hundred. So, the discount is equal to $384. To calculate the sales price, simply deduct the discount of $384 from the original price $3200 then get $2816 as the sales price.

The probability of winning on an arcade game is 0.659. if you play the arcade game 30 times. What is the probability of winning
stealth61 [152]

The probability of winning exactly 21 times is 0.14 when the probability of winning the arcade game is 0.659.

We know that binomial probability is given by:

Probability (P) = ⁿCₓ (probability of 1st)ˣ x (1 - probability of 1st)ⁿ⁻ˣ

We are given that:

Probability of winning on an arcade game = P(A) = 0.659

So, the Probability of loosing on an arcade game will be = P'(A) = 1 - 0.659 = 0.341

Number of times the game is being played = 30

We have to find the Probability of winning exactly 21 times.

Here,

n = 30

x = 21

P(A) = 0.659

P'(A) = 0.341

Using the binomial probability formula, we get that:

Probability of winning exactly 21 times :

P(21 times) = ³⁰C₂₁ (0.659)²¹ x (0.341)⁷

P( 21 times ) = 0.14

Therefore, the probability of winning exactly 21 times is 0.14
