Fill in the blank. class width is found by a. subtracting the smallest value in the data set from the largest value in the data set b. subtracting the lower limit of one class from the upper limit of that same class c. subtracting a lower class limit from the next consecutive lower class limit d. adding the lower class limit to the upper class limit and dividing by two

C. subtracting a lower class limit from the next consecutive lower class limit.

Step-by-step explanation:

Class width can be found by

Subtracting a lower class limit from the next consecutive lower class limit.

C. subtracting a lower class limit from the next consecutive lower class limit

Step-by-step explanation:

Class width can be defined as the difference between the upper and lower boundaries of any class. It may sometimes refer to;

1) the difference between the upper limits of two consecutive classes

2) the difference between the lower limits of two consecutive classes.

Therefore, class width can be found by subtracting a lower class limit from the next consecutive lower class limit.

$25

step-by-step explanation:

25 - 4.50 = 20.5

20.5 / 2 = 10.25

10.25 + 10 = 20.25

20.25 - 12.50 = 7.75

therefore the answer is $25 as shown as the first number.

5=812a+9+3

step 1: simplify both sides of the equation.

5=812a+9+3

5=(812a)+(9+3)(combine like terms)

5=812a+12

5=812a+12

step 2: flip the equation.

812a+12=5

step 3: subtract 12 from both sides.

812a+12−12=5−12

812a=−7

step 4: divide both sides by 812.

812a /812 = -7/812

a= -1/116

so the answer is

a=   -1/116
