Ira Lisetskai [31]

Answer: Mean = 27.33

Median = 27

Mode = 25 and 27

Step-by-step explanation:

1. Mean is the addition of all the numbers divided by how many numbers that are there.

Mean = (16 + 17 + 19 + 20 + 20 + 21 + 23 + 24 + 25 + 25 + 25 + 26 + 26 + 27 + 27 + 27 + 28 + 29 + 30 + 32 + 33 + 33 + 34 + 35 + 37 + 39 + 40) / 27

Mean = 738/27

Mean = 27.33

2. Median is the number in the middle in the ascending or descending other and this will be:

Median = 27/2 = 13.5 = 14th number = 27.

The median is 27.

3. Mode is the number that appears most and this will be 25 and 27 since they appear thrice which is the most times

Calculate x. Show all your work
Jlenok [28]

Step-by-step explanation:

126+y =180(sum of angles on a straight line is 180°)

y=180-126

y=54°

54+58+z=180(sum of interior angles of a triangle equals 180°)

112+z=180

z=180-112

z=68°

x+z=180(sum of angles on a straight line equals 180°)

x=180-z

x=180-68

x=112°

Two step inequalities intergers
wlad13 [49]
.Two-step inequalities<span> are very easy to solve and the rules you have to adhere to are the same as for the one-step inequalities – remember that you need to change the sign of inequality when </span><span> multiplying or </span>dividing<span> the whole inequality with a negative number. The </span>order of operations<span> will not come into play often since there are not many operations to perform here.
