Will give brainliest and 100 points
____ [38]

Answer:

Kayla plays on average 0.2 more chess games than Becker

Step-by-step explanation:

The first thing we must do is calculate the mean of each one.

Becker:

(5 + 2 + 4 + 1 + 1 + 4 + 5 + 3 + 2 + 1) / 10 = 2.8

Kayla:

(2 + 3 + 1 + 1 + 4 + 1 + 5 + 3 + 5 + 5) / 10 = 3

if we subtract these averages, we have to:

3 - 2.8 = 0.2

which means that Kayla plays on average 0.2 more chess games than Becker. Since it is not even a complete game, the difference between the two is very small and almost irrelevant.

The area of a rectangular picture frame is 4 1/3 square inches. The length of the frame is 3 1/2 inches. Find the width of the f
goldenfox [79]

Answer:

13/14

Step-by-step explanation:

Area of a rectangle = l * b

=> 4 1/3 = 3 1/2 + b

=> (4 1/3) / (3 1/2) = b

=> (13/4) / 7/2  = b

=> 13/4 * 2/7

=> 13/2 * 1/7

=> 13/14

Therefore the width = 13/14

If my answer helped, kindly mark me as the brainliest!!

Thank you!!

1. Which expresses the given inequality in interval notation?
Digiron [165]
1)  x < 4  the answer is  <span>  Option C: x E(-infinity,4)  (it is strict)
2)  </span>2x +6 < 8, and  <span>2x < 8 - 6 = 2, and x<2/2=1
the answer is </span>
<span>D. x E (-infinity, 1)
</span>3)  <span>X greater than or equal to 8 and  x <  - 4
</span>X greater than  8  means x ≥ 8
so we have x ≥ 8 and  <span> x <  - 4
so the answer is  </span>
<span>B. x E (-4,8]
</span> 4) 
7 > x + 6 or x -2 greater than or equal to 3,
<span>7 > x + 6 or x -2 ≥ 3
</span>
<span>7 -6> x, and 1>x
</span>
x -2 ≥ 3   x<span>≥ 3+2=5
finally
</span>x<1 and x≥5   

the answer is
<span>C.x E (1,5]
5)
</span>
|x+3| > 12, 
|x+3| = { -(x+3) if <span>x+3<0 or  </span><span>(x+3)  if </span><span>x+3>0}</span>

so, it is  -(x+3)>12 is equivalent to (x+3)< -12  or (x+3)>12
the answer is
<span>B. x + 3 > 12 or x + 3 <-12</span>
