Answer:

The amount of popcorn needed to  fill the paper cone is V=1,005\ cm^{3}

Step-by-step explanation:

we know that

The volume of a cone is equal to

V=\frac{1}{3}\pi r^{2} h

In this problem we have

r=8\ cm

h=15\ cm

\pi =3.14

substitute

V=\frac{1}{3}(3.14)(8)^{2}(15)

V=1,005\ cm^{3}

Find the values of the mode when median is given to be 5 and mean is 7.
Reil [10]

Answer:

<u>Mode = 1</u>

Step-by-step explanation:

<u>Relation between the Central Measures of Tendency</u>

  • Mean, Median, and Mode are commonly referred to as the Central Measures of Tendency
  • The formula between the three is given by :
  • ⇒ <u>Mode = 3Median - 2Mean</u> or <u>Mode + 2Mean = 3Median</u>

<u></u>

<u>Solving</u>

  • We know that :
  1. Median = 5
  2. Mean = 7

Therefore,

  • Mode = 3(5) - 2(7)
  • Mode = 15 - 14
  • <u>Mode = 1</u>

Find the solutions to the system of equations. Select all that apply. Y=x^2-1 y=2x-2
Sliva [168]

Answer:

Option C (1, 0)

Step-by-step explanation:

We have a system with the following equations:

y = x ^ 2-1\\\\y = 2x-2

The first equation is a parabola.

The second equation is a straight line

To solve the system, substitute the second equation in the first and solve for x.

2x-2 = x ^ 2 -1

Simplify

x ^ 2-2x + 1 = 0

You must search for two numbers that when you add them, obtain as a result -2 and multiplying both results in 1.

These numbers are -1 and -1

Therefore

x ^ 2-2x + 1= (x-1)(x-1)\\\\x ^ 2-2x + 1= (x-1)^2=0

Finally the solutions are

x = 1\\y =0
