(b - 4z)/7 = a
b - 4z = 7a
b = 7a + 4z
Answer: b = 7a + 4z
Answer:
See Explanation
Step-by-step explanation:
The question is incomplete, as the required lengths are not given.
I will use the following data set to answer the question.

First, is to determine the range of the dataset



Next, we will make use of 4 classes. So, we divide range by 10 to get the number of class. 10 represents the interval




<em>So, we use 4 classes</em>
Plot the frequency distribution table as follows:

<em>See attachment for histogram</em>
Percent error=|

| times 100
(note the || is absolute value, means that whatever the result is inside, it is made positive)
predicted value=261
actual value=293
subsitute
percent error=|

| times 100
so using pemdas
do parenthasees first
|

|
|-0.12|
absolute value
0.1226
time 100
0.1226 times 100=12.26
answer is 12.26%
answer is B
