Answer:

Slope: 16

y-intercept: (0, 0)

<u>Yes</u> it is proportional

Step-by-step explanation:

<h2>What's the slope</h2>

To find the slope we can do rise over run.

 192 - 96           96

----------------- = ----------- = 16

    12 - 6              6

So the slope is 16

<h2>What is the y-intercept?</h2>

For the y intercept we can just look where the line crosses the y-line so (0, 0)

We can check that by inputing some numbers:

y = mx + b -------> 96 = 6 · 16 + b

                            96 = 96 + b

                            - 96     - 96

                               0 = b

in this equation b represents the y-intercept

<h2>Is it proportional?</h2>

And the definition of a proportional slope is if the equation is y = mx, which in this case it is true, as the equation is y = 16x. (m is the slope which we've already found above)

So evidently the slope is proportional.

The slope is 1, so put either “x” or “1” and the y-intercept is at the origin so it’s 0, so put “(0,0)”

I played 4 games of badmintonand scored 12 points per game. The average score of the first 3 games was 10 points per game. how m
Ne4ueva [31]
You scored 18 points in your fourth game because if you played 4 games and got 12 points each game that equals 48 points all together and if the average is 10 points for the first 3 games that equals 30 points for the three games so 48-30=18

BlueSky Air has the best on-time arrival rate with 80% of its flights arriving on time. A test is conducted by randomly selectin
Strike441 [17]

Answer:

0.211 = 21.1% probability that 2 flights of BlueSky Air arrive late

Step-by-step explanation:

For each flight, there are only two possible outcomes. Either they arrive late, or they do not. The probability of a flight arriving late is independent of any other flight. This means that the binomial probability distribution is used to solve this question.

Binomial probability distribution

The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.

P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}

In which C_{n,x} is the number of different combinations of x objects from a set of n elements, given by the following formula.

C_{n,x} = \frac{n!}{x!(n-x)!}

And p is the probability of X happening.

BlueSky Air has the best on-time arrival rate with 80% of its flights arriving on time.

This means that 100 - 80 = 20% are late, which means that p = 0.2

Randomly selecting 16 BlueSky Air flights

This means that n = 16

What is the probability that 2 flights of BlueSky Air arrive late?

This is P(X = 2).

P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}

P(X = 2) = C_{16,2}.(0.2)^{2}.(0.8)^{14} = 0.211

0.211 = 21.1% probability that 2 flights of BlueSky Air arrive late

Answer:

I could do 1 and 3

1) 2x-3y=-2 ....1

-

2x+y=14......2

=-4y=-16

y=4

<u>Substitute</u><u> </u><u>(</u><u>y</u><u>=</u><u>4</u><u>)</u><u> </u><u>into</u><u> </u><u>equation</u><u> </u><u>1</u>

2x-3 (4)=-2

2x-12=-2

2x=-2+12

2x=10

×=5

3) 5x+5y=20....1

-

-3x+5y=4......2

=8x=16

x=2

<u>S</u><u>ubstitute</u><u> </u><u>(</u><u>x</u><u>=</u><u>2</u><u>)</u><u> </u><u>into</u><u> </u><u>equation</u><u> </u><u>1</u>

<u>5</u><u> </u><u>(</u><u>2</u><u>)</u><u>+</u><u>5y</u><u>=</u><u>20</u>

<u>10</u><u>+</u><u>5y</u><u>=</u><u>20</u>

<u>5y</u><u>=</u><u>20-10</u>
