Answer:

The expected value of one draw is the average value of these 10 slips of paper which is:

24 / 10  =  2.4

Step-by-step explanation:

We have a bag with 10 slips of paper in it. 8 slips of paper each has a 2 on them; 2 slips of paper each has a 4 on them.

The total value of all the slips when added together is:

= (8)(2) + (2)(4)  

=  16 + 8 = 24

The expected value of one draw is the average value of these 10 slips of paper which is:

24 / 10  =  2.4  ....

HELP ASAP!!!<br> Find the slope of this equation: <br> 6x+6=−4y
Dmitriy789 [7]

Answer:

the slope is -3/2

Step-by-step explanation:

We need to get the equation in the form

y = mx +b where m is the slope and b is the y intercept

6x+6 = -4y

Divide by -4

-6x/-4 +6/-4 = -4y/-4

-3/2 x -3/2 = y

The slope is -3/2 and the y intercept is -3/2

<span>  <span>first off your answer is 21.90 and the step by step i  wrote it for you:) Finding the square root of a number is the inverse operation of squaring that number. Remember, the square of a number is that number times itself. </span> The perfect squares are the squares of the whole numbers. The square root of a number, n, written below is the number that gives n when multiplied by itself.   </span>                                                                                                                                                                          <span>Many mathematical operations have an inverse, or opposite, operation. Subtraction is the opposite of addition, division is the inverse of multiplication, and so on. Squaring, which we learned about in a previous lesson (exponents), has an inverse too, called "finding the square root." Remember, the square of a number is that number times itself. The perfect squares are the squares of the whole numbers: 1, 4, 9, 16, 25, 36, 49, 64, 81, 100 … </span> The square root of a number, n, written <span> is the number that gives n when multiplied by itself.

Finding square roots of of numbers that aren't perfect squares without a calculator 1. Estimate - first, get as close as you can by finding two perfect square roots your number is between. 2. Divide - divide your number by one of those square roots.
3. Average - take the average of the result of step 2 and the root. <span>4. Use the result of step 3 to repeat steps 2 and 3 until you have a number that is accurate enough for you.

15 For exercise, Cindy swims every 6 days and jogs every 8 days. She did both today.
Drupady [299]

Answer:

24 days

Step-by-step explanation:

To find the answer we need to find the LCM

first, find the prime factorization of 6 and 8

6=2*3

8=2^3

8*3=24

So she'll swim and jog on the same day in 24 days

The perimeter of given figure is 20 meters.

Step-by-step explanation:

Given lengths of shape are;

3m, 4m, 7m, 1m, 5m

We have to find the perimeter of the shape.

A perimeter is the length of outline or boundary of any shape.

Perimeter of the shape = Sum of lengths

Perimeter of the shape = 3+4+7+1+5

Perimeter of the shape = 20 meters

The perimeter of given figure is 20 meters.

Keywords: addition, perimeter
