Answer:

Step-by-step explanation:

The given line's equation is in slope-intercept form:

y = mx + b

where m = -4 is the slope, and b = -1 is the y-intercept.

The slope of the perpendicular line will be ...

-1/m = -1/(-4) = 1/4

You want the point-slope equation for the line, which is ...

y -k = m(x -h) . . . . line with slope m through point (h, k)

Your equation will have m=1/4, (h, k) = (-2, 7), so it will be ...

y -7 = 1/4(x +2)

F(x)= -2x^2<br>what is the vertex of this and/or how do you find the vertex??

Doss [256]

Answer:

(0,0)

Step-by-step explanation:

x value of vertex = -b/2a

ax^2+bx+c

-2x^2+0x+0 sinc you have no value of b & c in your quadratic function

-b = 0

2a = (2)(-2)

-b/2a = (0/-4) = 0

x value of the vertex = 0

plug 0 in for all values of x in the function to find y coordinate value

-2(0)^2 = 0

(x,y) = (0,0)

The average score of this quiz is 24 points with a standard deviation of 1.5 points. What is the probability that someone scored

navik [9.2K]

Answer:

8.08 %

Step-by-step explanation:

Let us denote : $X=$ score X follows a normal distribution with mean $=24$ and standard deviation $=1.5$

Step 2

The probability that someone scored 21.9 or less is :

$\mathrm{P}(\mathrm{X} \leq 21.9)$

$=\mathrm{P}\left(\mathrm{Z} \leq \frac{21.9-24}{1.5}\right)$

$=\mathrm{P}(\mathrm{Z} \leq-1.4)$

$=0.0808$

$=8.08%$

Answer : $8.08 %$

Suzanne can read 1 page in 3 minutes. how many pages can she read in 5 hours?

pychu [463]

If Suzanne can read 1 page in 3 minutes, that means that in ONE hour, she can read 20 pages.
1 page per 3 minute
60minutes : 3 = 20 pages
Now, multiply 20 pages by 5 hours.
20 x 5 = 100.

I hope it helps! (She's pretty slow at reading)
