Answer:

y=3x+1, or the second option

Step-by-step explanation:

We can see on the graph the line converges with the y-axis at (0, 1), so we can cross out the last two answers. Then we can also see that the slope is 3 on the graph and an equation that has x^2 must be a parabola. The answer is then narrowed down to the second option.

A 208-yard-long road is divided into 16 parts of equal length. Mr.Ward paints a 4-yard-long strip in each part. How long is the
Andreas93 [3]

Answer:

Length of unpainted strip of each part of the road = 9 yard

Step-by-step explanation:

Total length of the road = 208 yard

When it is divided into 16 equal parts,

length of each part = \frac{208}{16}

                                 = 13 yard

Mr.Ward paints 4 yard long strips in each part .That is he does not completely paint the part but paints only a small section of each part.

Length of unpainted strip of each part of the road = length of each strip - length of strip painted by Mr.Ward

Length of unpainted strip of each part of the road = 13 - 4

Length of unpainted strip of each part of the road = 9 yard

Flight 202's arrival time is normally distributed with a mean arrival time of 6:30 p.m. and a standard deviation of 15 minutes.
natta225 [31]

Answer:

The probability is 0.0015

Step-by-step explanation:

We know that the mean \mu is:

\mu=6:30\ p.m

The standard deviation \sigma is:

\sigma=0:15\ minutes

The Z-score is:

Z=\frac{x-\mu}{\sigma}

We seek to find

P(x>7:15\ p.m.)

The Z-score is:

Z=\frac{x-\mu}{\sigma}

Z=\frac{7:15-6:30}{0:15}

Z=\frac{0:45}{0:15}

Z=3

The score of Z = 3 means that 7:15 p.m. is 3 standard deviations from the mean. Then by the rule of the 8 parts of the normal curve, the area that satisfies the conficion of 3 deviations from the mean has percentage of 0.15%

So

P(x>7:15\ p.m.)=P(Z>3)=0.0015

Use the method of completing the square to transform the quadratic equation into the equation form (x – p)2 = q. x2 - 12x - 9 =
marissa [1.9K]

Hence, the correct answer is: C) (x - 6)^2 = 45

Further explanation:

Given equation is:

x^2-12x-9=0

We will move the constant term on other side of the equation

x^2-12x=9

To complete the square, we will take the coefficient of x and divide it by 2, as we already know that one term is x.

\frac{12}{2}=6

So, adding (6)^2 on both sides

(x)^2-2.x.6+(6)^2=9+(6)^2\\(x-6)^2=9+36\\(x-6)^2=45

Hence, the correct answer is: C) (x - 6)^2 = 45
