3x+7=5x
-3x -3x
7=2x
(Divide both sides by 2)
x=3.5

Your subtracting 3x from 5x: 5x-3x
This is so you only have a variable on one side

Write down all of the #'s on a piece of paper
18,23,15,16,15,17,22,16,19,11,24,14,12,16,20,18,14,13,21,11

Put them in order
11,11,12,13,1414,15,15,16,16,16,17,18,18,19,20,21,22
Cross em off on eah side until you reach the middle 
16, 16
Since there's 2 instead of 1 middle # Add up the 2 (16+16 = 32) 
Then divide by 2 (32/2 = 16)

You're answer is 16

1..Suppose an experiment has five equally likely outcomes: E1, E2, E3, E4, E5. Assign probabilities to each outcome and show tha
stellarik [79]

Answer:

1.

P(E1)=P(E2)=P(E3)=P(E4)=P(E5= )1/5

2.

P(E1)=0.4

P(E2)= 0.26

P(E3)=0.34

3.

No the probability assignments are invalid

Step-by-step explanation:

1

Total number of possible outcomes = 5

<u>Equation (4.3)</u>

0< P(Ei)<1

<u>Equation (4.4)</u>

P(E1) + P(E2) +........+P(En)=1

As the outcomes are equally likely therefore,

Probability for each outcome= P(Ei) = 1/5

2

Total number of outcomes = 50

Outcomes for event E(1)= 20

Outcomes or event E(2)= 13

Outcomes or event E(3) = 17

P(Ei)= (number of outcomes for event Ei/ Total number of outcomes)

P(E1)=20/50=0.4

P(E2)= 13/50=0.26

P(E3)=17/50=0.34

3

P(E1) .10,

P(E2) .15,

P(E3) .40,

P(E4) .20

0.1 +0.15+0.40+0.20=0.85<1

According to  equation (4.4) the probability assignments are invalid as the sum of probabilities for all outcomes must be equal to 1.

Find the height of a cone with volume 4034.66 cm^3 and radius 13 cm.
pav-90 [236]
Volume of cone=4034.66cm^3
Pi×r^2×h/3=4034.66
Pi×13×13×h=4034.66×3
22×13×13×h/7=4034.66×3
h=4034.66×3×7/13×13×22
h=45.57
So h=45.6cm
