Answer:

Step-by-step explanation:

P (blue)  fraction = 2/8   decimal=.25     percent=25%

P(purple) fraction=0/8   decimal=0         percent =0%

P(not green)  fraction=5/8     decimal=.625     percent= 62.5%

P(not brown) fraction=8/8     decimal=1   percent =100%

2)Refer to the table on air travel selected airports. Suppose a flight that arrived at <u>El Centro</u> is selected at random. What is the probability that the flight <u>did not arrive on time?</u> write your answer as a fraction, decimal and percent.    

80% on time so 20% are not on time

20/100 ÷ 20 =1/5

20%, .2, 1/5

3)The spinner has 8 sectors labeled with letters. Each sector of the spinner below is the same size, as shown.

If the arrow is spun 400 times , how many times  would it be  expected to land on a sector labeled B?

\frac{B}{Total} \\\frac{3}{8} =\frac{x}{400\\}

A)50                 C)150

B)100                D)250

Vadim26 [7]

Answer:   \bold{\dfrac{12\pm \sqrt{144-0}}{2(17)}}

<u>Step-by-step explanation:</u>

17x^2=12x\quad \rightarrow \quad 17x^2-12x+0=0\quad \rightarrow \quad a=17,\ b=-12,\ c=0\\\\\\\text{Quadratic formula is: }x=\dfrac{-b\pm \sqrt{b^2-4ac}}{2a}\\\\\\x=\dfrac{-(-12)\pm \sqrt{(-12)^2-4(17)(0)}}{2(17)}\\\\\\.\ =\dfrac{12\pm \sqrt{144-0}}{2(17)}

The answer is X = 6

Because 3 times 2 x is 6x ... then -1 plus 1 is 0 so it levels out and x is 6

What is an equation of the line that passes through the points (6, 0) and (-1, -7)?
Orlov [11]

Answer:

y = x - 6

Step-by-step explanation:

We want to write a line in slope-intercept form, which is y = mx + b, where m is the slope and b is the y-intercept.

First, we need to find the slope, which is just the change in the y-coordinates divided by the change in the x-coordinates:

slope = m = \frac{6-(-1)}{0-(-7)} =\frac{7}{7}=1

Our equation now looks like this: y = x + b

Now, to find the y-intercept, let's use one of the points provided and plug those values of x and y into the incomplete equation we have to solve for b:

0 = 6 + b  ⇒  b = -6

So, the equation is: y = x - 6.

Hope this helps!
