Step-by-step explanation:

Let the number be x.

4-4x= 2x

4= 2x+4x

4= 6x

6x=4

x= 4/6

x= 2/3

Hope it helps :)

Answer:

$1 \to 22 \to 0.176$

$2 \to 13 \to 0.104$

$3 \to 18 \to 0.144$

$4 \to 29 \to 0.232$

$5 \to 37 \to 0.296$

$6 \to 6 \to 0.048$

Step-by-step explanation:

Given

$n = 125$

See attachment for proper table

Required

Complete the table

Experimental probability is calculated as:

$Pr = \frac{Frequency}{n}$

We use the above formula when the frequency is known.

For result of roll 2, 4 and 6

The frequencies are 13, 29 and 6, respectively

So, we have:

$Pr(2) = \frac{13}{125} = 0.104$

$Pr(4) = \frac{29}{125} = 0.232$

$Pr(6) = \frac{6}{125} = 0.048$

When the frequency is to be calculated, we use:

$Pr = \frac{Frequency}{n}$

$Frequency = n * Pr$

For result of roll 3 and 5

The probabilities are 0.144 and 0.296, respectively

So, we have:

$Frequency(3) = 125 * 0.144 = 18$

$Frequency(5) = 125 * 0.296 = 37$

For roll of 1 where the frequency and the probability are not known, we use:

$Total \ Frequency = 125$

So:

Frequency(1) added to others must equal 125

This gives:

$Frequency(1) + 13 + 18 + 29 + 37 + 6 = 125$

$Frequency(1) + 103 = 125$

Collect like terms

$Frequency(1) =- 103 + 125$

$Frequency(1) =22$

The probability is then calculated as:

$Pr(1) = \frac{22}{125}$

$Pr(1) = 0.176$

So, the complete table is:

$1 \to 22 \to 0.176$

$2 \to 13 \to 0.104$

$3 \to 18 \to 0.144$

$4 \to 29 \to 0.232$

$5 \to 37 \to 0.296$

$6 \to 6 \to 0.048$

What is the value of x? x−2/5=7 Enter your answer in the box in simplest form. x =

fenix001 [56]

Answer:

Your answer is 17.5

Step-by-step explanation:

Turn your fraction into a decimal

2/5 = 0.4

Next multiply my given answer by 0.4

17.5 x 0.4 = 7

Therefore 17.5 is your final answer

If one end of a line segment is (4, 4) and midpoint is (-2,2), find the co-ordinates of the other end.

Soloha48 [4]

Answer:

-8,0

Step-by-step explanation:

From one end of a segment to the midpoint, it takes -6x to get to the midpoint. Based on that, you can go another 6 over the y graph and get -8 for x.

For y, the segment goes from 4 to 2 (a -2 over the x graph). you can infer then that the other end will be 0.

In some country's congress, the number of representatives is 25 less than five times the number of senators. there are a total

Nataliya [291]

Let number of senators = x, then:-

number of representatives = 5x - 25 so

x + 5x - 25 = 515
6x = 540
x = 90
number of reps = 515 - 90 = 425

so there are 90 senators and 425 representatives.
