I NEED HELP ASAP!!!!!!
krek1111 [17]

Answer:

83.3%

Step-by-step explanation:

The probability of rolling a 3 on a 6-sided dice is 1/6

Since you don't want a three, there's a 5/6 chance of not rolling a 3

5/6 (use calculator and divede 5 by 6) = 0.833333 (move decimal 2 to the right) = 83.3%

Therefore, the most reasonable answer would be C, 83.3%

A number decreased by the total of the number and fourteen
Charra [1.4K]

The answer to this would be x-(x+14)

Here's an explanation:

Let x represent the unknown number. The problem says that x has been decreased by the sum of x and 14. So, to put this in a form of an equation, it would be x-(x+14), since you have to do the addition first before you can subtract the two number since you don't know what x is. This equation is equal to -14 no matter what x is.

Find the mean, median, mode, and range of this data: 49, 49, 54, 55, 52, 49, 55. If necessary, round to the nearest tenth.
Zigmanuir [339]
The mean is the average.
So, to find the mean you want o add up all of the numbers and then divide by the number of numbers.

49 + 49 + 54 + 55 + 52 + 49 + 575 = 363
363 / 7 = 51.85
Rounded to 52

For the median you want o line all of your number up from least to greatest and then find the middle number.

49,49,49,52,54,55,55

Your median is 52

The mode is the number that is listed most often

49 is listed 3 times
54 is listed 1 time
52 is listed 1 time
55 is listed 2 times

So, your mode is 49

Please select the best answer and click submit Solve kx-4=9 for x
shepuryov [24]

Answer:

Option B. x = \frac{13}{k}.

Step-by-step explanation:

The given equation is kx - 4 = 9

We will add 4 on both the sides of the equation

kx - 4 +4 = 9 +4

kx = 13

Now we will divide by k on both the sides of the equation

\frac{1}{k}(13x) = \frac{1}{k}13

x = \frac{13}{k}

Therefore Option B x = 13/k is the right answer.
