Write an equation for each line.

Mathematics
1 answer:
Effectus [21]3 years ago
3 0

Answer:

y = -x+2

Step-by-step explanation:

We know the y intercept is 2  ( where it crosses the y axis)

We know two points on the line

(0,2) and (2,0), so we can find the slope

m = ( y2-y1)/(x2-x1_

   = (0-2)/(2-0)

   = -2/2

  = -1

The slope intercept form of the line is

y = mx+b where m is the slope and b is the y intercept

y = -1x +2

y = -x+2

A rectangular prism that has a length of 8 feet, width of 6 feet, and height of 12 feet. What is the volume of the prism? ft3
Lady bird [3.3K]

Answer:

The volume of the prism is 576 cubic feet

Step-by-step explanation:

Length of rectangular prism = 8 feet

Width of rectangular prism = 6 feet

Height of rectangular prism = 12 feet

Volume of rectangular prism = Length \times Breadth \times Height

Volume of rectangular prism =8 \times 6 \times 12

Volume of rectangular prism =576 feet^3

Hence the volume of the prism is 576 cubic feet

Let f(x)=49 -x^2, g(x)=7-x. Find (f-g)(x)
Karolina [17]
F(x) = -x² + 49
g(x) = -x + 7

(f - g)(x) = (-x² + 49) - (-x + 7)
(f - g)(x) = (-x² + 49) + (x - 7)
(f - g)(x) = -x² + x + 49 - 7
(f - g)(x) = -x² + x + 42

The shuttle bus from your parking lot and your office building operates on a 15 minute schedule. You arrive at the parking lot a
mylen [45]

Answer:

(a) The standard deviation of your waiting time is 4.33 minutes.

(b) The probability that you will have to wait more than 2 standard deviations is 0.4227.

Step-by-step explanation:

Let <em>X</em> = the waiting time for the bus at the parking lot.

The random variable <em>X</em> is uniformly distributed with parameters <em>a</em> = 0 to <em>b</em> = 15.

The probability density function of <em>X</em> is given as follows:

f_{X}(x)=\frac{1}{b-a};\ a

(a)

The standard deviation of a Uniformly distributed random variable is given by:

SD=\sqrt{\frac{(b-a)^{2}}{12}}

Compute the standard deviation of the random variable <em>X</em> as follows:

SD=\sqrt{\frac{(b-a)^{2}}{12}}

      =\sqrt{\frac{(15-0)^{2}}{12}}

      =\sqrt{\frac{225}{12}}

      =\sqrt{18.75}\\=4.33

Thus, the standard deviation of your waiting time is 4.33 minutes.

(b)

The value representing 2 standard deviations is:

X=2\times SD=2\times4.33=8.66

Compute the value of P (X > 8.66) as follows:

P(X>8.66)=\int\limits^{10}_{8.66} {\frac{1}{15-0}}\, dx\\

                    =\frac{1}{15}\times \int\limits^{10}_{8.66} {1}\, dx\\

                    =\frac{1}{15}\times |x|^{15}_{8.66}\\

                    =\frac{15-8.66}{15}\\

                    =0.4227

Thus, the probability that you will have to wait more than 2 standard deviations is 0.4227.
