Four diners have ordered a platter of desserts. The platter holds 8 chocolate chip cookies and 4 slices of chocolate cheesecake.

Furkat [3]

Answer:

$P(Y>1 \cap Y$

And we can find this probability like this:

$P(Y>1 \cap Y$

And we can replace the values and we got:

$P(Y>1 \cap Y$

Step-by-step explanation:

For this case we define the random variable Y as: the number of slices of cheesecake left on the platter after the first serving. And we have the following distribution for Y:

Y | 0 1 2 3 4

P(Y) | 0.005 0.114 0.429 0.381 0.071

And we want to find the following probability:

$P(Y>1 \cap Y$

And we can find this probability like this:

$P(Y>1 \cap Y$

And we can replace the values and we got:

$P(Y>1 \cap Y$

A pharmaticeutical company is making a new medicine capsule shaped like a cylinder with a half sphere at each end. The

DerKrebs [107]

Answer:

339.12 cubic millimeters

Step-by-step explanation:

The picture of the question in the attached figure

we know that

The volume of the figure is equal to the volume of the two hemispheres (one sphere) plus the volume of the cylinder

step 1

Find the volume of the cylinder

The volume is given by

$V=Bh$

where

B is the area of the base of cylinder

h is the height of cylinder

we have

$B=\pi r^{2}$

we have

$h=8\ mm$

$r=6/2=3\ mm$ ----> the radius is half the diameter

$B=(3.14)(3)^{2}$

$B=28.26\ mm^2$

substitute

$V=(28.26)(8)=226.08\ mm^3$

step 2

Find the volume of the sphere

The volume is given by

$V=\frac{4}{3}\pi r^{3}$

we have

$r=6/2=3\ mm$ ----> the radius is half the diameter

substitute

$V=\frac{4}{3}(3.14)(3)^{3}=113.04\ mm^3$

step 3

Adds the volumes

$226.08+113.04=339.12\ mm^3$

-1 3/5 divided by -2/3 written as mixed number

blondinia [14]

First, you must change all of this into improper fractions, like shown below.
$- \frac{8}{5}\div - \frac{2}{3} =$
Now you must change the sign.
$- \frac{8}{5}* - \frac{2}{3} =$
Then we must reciprocalize 2/3.
$- \frac{8}{5}* - \frac{3}{2} =$
Now we multiply, to get 2 4/10.

Explain why this statement is true:<br> 7a +4 – 2a = 7a + (-20)+4

MAVERICK [17]

Answer:

This equation has one solution so given statement is true.

Step-by-step explanation:

7a +4 – 2a = 7a + (-20)+4

5a + 4 = 7a - 16

5a - 7a = -16 - 4

- 2a = - 20

a = 10

This equation has one solution so given statement is true.

How can you recognize when a pattern in real life is linear or nonlinear?

andreev551 [17]

Answer:

Step-by-step explanation:

If a table is linear, Y must change at a constant rate as X increases by 1. If a table is not linear, Y doesn't change at a constant rate at all. In fact, nonlinear tables don't even have an equation because there's no predicting what the Y-value is.
