Answer:

The die lands with a​ 1, 2,​ 3, 4, or 5 on top ⇒ answer D

Step-by-step explanation:

- Complementary events are two outcomes of an event that are the

 only two possible outcomes

- The Complement Rule states that the sum of the probabilities of

  an event and its complement must equal 1

- P(A) + P(A') = 1

- Lets solve the problem

- The event A is:

  " a die lands with a 6 on​ top "

∴ P(A) = \frac{1}{6}

∵ P(A) + P(A') = 1

∴ \frac{1}{6} + P(A') = 1

- Subtract \frac{1}{6} from both sides

∴ P(A') = \frac{5}{6}

∵ The die has six numbers from 1 to 6

∴ The other numbers than 6 are 1 , 2 , 3 , 4 and 5

∴ The complement of event A is:

   " A die lands with 1 , 2 , 3 , 4 or 5 "

* The complement of the event is:

 The die lands with a​ 1, 2,​ 3, 4, or 5 on top

The phony bologna meat company offers two platters. platter a comes with 4 hamburgers, 3 hot dogs, and 2 pig's feet, and costs $
Brrunno [24]
The solution for this problem is:
If there is 60 platters of B at a cost of $720: 
(220 - 60 x 3) / 4 = 10 platters of A to make up for the deficit in hamburgers 
(270 - 60 x 4) / 3 = 10 platters of A to make up for the deficit in hot dogs 
(250 - 60 x 5) / 2 = 0 platters of A since there is no deficit in pigs feet 

So 10 platters A are required at a cost of $150. $720 + $150 = for a total minimum cost of $870.

The formula for the volume of a pyramid is V=(1/3) ⁢B⁢h, where B is the area of the base and h is the height. Rearrange the form
PIT_PIT [208]
To make an equation that solves for the height as according to the volume of a pyramid, you must isolate the variable h on one side.

The first thing you have to do is to multiply both sides by 3 to get 3V=Bh.

Then, divide both sides by B to get your answer as h=3V/B.

Dafna11 [192]

Answer:

Third option is correct. Scale factor 3 ; enlargement.

Step-by-step explanation:

It is given that the figure A'B'C'D' is a dilation of figure ABCD.

We know that after dilation the corresponding sides of image and preimage are in the same proportion.

The image of AD is A'D'.

From the figure it is noticed that the A(-1,2), D(-1,-1), A'(-3,6) and D'(-3,-3).

Distance formula is

d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}

AD=\sqrt{(-1+1)^2+(-1-2)^2}=\sqrt{9}=3

A'D'=\sqrt{(-3+3)^2+(-3-6)^2}=\sqrt{81}=9

Scale factor is constant which represents the relation between image and preimage.

k=\frac{A'D'}{AD}

k=\frac{9}{3}

k=3

Therefore the scale factor is 3.

If k>0 it means enlargement and if k<0 it means reduction. Therefore third option is correct.
