kobusy [5.1K]4 years ago
5 0

Answer:

y- intercept = - 10 or (0, - 10 )

Step-by-step explanation:

to find the y-intercept, that is where the graph crosses the y- axis let x = 0 in the equation

f(0) = - \frac{1}{3} (3)³ - 1

     = - \frac{1}{3} × 27 - 1 = - 9 - 1 = - 10

Let x be the amount of time (in hours) the wait is to get a table at a restaurant. Suppose the cdf is represented by f(x)=⎧⎩⎨⎪⎪⎪
sattari [20]

Option a is correct. The calculated answer is 0.150

<h3>How to get the value using the cdf</h3>

In order to get  P(0.5 ≤ X ≤ 1.5).

This can be rewritten as

p = 0.5

and P = 1.5

We have the equation as

\frac{1}{16} x^{2}

This would be written as

1.5²/16 - 0.5²/16

= 0.1406 - 0.015625

= 0.124975

This is approximately 0.1250

What's the Volume of this??
mr_godi [17]

Answer:

V = 90 cm^3

Step-by-step explanation:

The volume is given by

V = Bh

where B is the area of the base and  h is the height

The base is the two sides that are identical, which is the triangle

B = 1/2 bh

   = 1/2 (4*3)

   = 1/2 (12)

   = 6

Substituting into the volume equation, where h = 15

V = 6*15

V = 90 cm^3

Examine this system of equations. Which number can be multiplied by each equation so that when the two equations are
andreyandreev [35.5K]

Answer:

15 times the first equation and -12 times the second equation

Step-by-step explanation:

we have

\frac{3}{4}x+\frac{2}{3}y=6 ------> first equation

\frac{5}{8}x+\frac{5}{6}y=12 ------> second equation

Multiply the first equation by 15 both sides

(15)\frac{3}{4}x+(15)\frac{2}{3}y=6(15)

\frac{45}{4}x+10y=90 -----> new first equation

Multiply the second equation by -12 both sides

(-12)\frac{5}{8}x+(-12)\frac{5}{6}y=12(-12)

-\frac{60}{8}x-10y=-144 -----> new second equation

Adds the two new equations

\frac{45}{4}x+10y=90\\-\frac{60}{8}x-10y=-144\\-----------\\\frac{45}{4}x-\frac{60}{8}x=90-144

The y-term was eliminated
