Find the mean for the set of data.<br> 0.2, 0.21, 0.17, 3.22, 0.2
Sholpan [36]

Answer:

0.8

Step-by-step explanation:

Find the mean of the list:

(0.2, 0.21, 0.17, 3.22, 0.2)

The mean of a list of numbers is given by:

(sum of elements)/(number of elements)

(sum of elements) = 0.2 + 0.21 + 0.17 + 3.22 + 0.2:

(0.2 + 0.21 + 0.17 + 3.22 + 0.2)/(number of elements)

Counting, we see that the list has 5 elements:

(0.2 + 0.21 + 0.17 + 3.22 + 0.2)/5

0.2 + 0.21 + 0.17 + 3.22 + 0.2 = 4:

4/5

4/5 = 0.8:

Answer:  0.8

Maria and victor each play a video game. The ratio of the number of points Maria scores to the number of points victor scores is
zvonat [6]

Answer:

Step-by-step explanation:

I don't know what a tape diagram is but I can give you the equation and the answer.

Let Victor have x points

Let Maria have y points

y = x + 424

y/x = 5/3                     Cross multiply

3y = 5x                       Divide by 3

y = 5x/3                      I Could have just multiplied by x

y = x + 424

5x/3 = x + 424           Multiply both sides by 3

5x = 3x + 1272           Subtract 3x from both sides.

5x-3x = 1272              Combine the left.

2x = 1272                    Divide by 2

2x/2 = 1272/2

x = 636

Victor Scored 636 points

Maria Scored 636 + 424 = 1060

Find the value of X. .
Sliva [168]

The value of x is 12. 94°

<h3>How to determine the angle</h3>

From the diagram shown, we can see that the two angles are on a straight line.

It is important to note that angles on a straight line sum up to 180 degrees

Hence, we have;

(11x- 15) + 5x - 12 = 180°

collect like terms

11x + 5x - 15 - 12 = 180

Add like terms

16x - 27 = 180

16x = 180 + 27

16x = 207

Make 'x' the subject of formula

x = 207/ 16

x = 12. 94°

Thus, the value of x is 12. 94°
