It is a good sampling method because it will show a varied amount of hours per person. Not everyone works at the same business so they will all be different. If he was to survey everyone in the high school then he would have an even MORE varied chart of hours each person works.
Answer:
4 times
Step-by-step explanation:
35/(3+3+2) = circa 4
Follow the a² + b² = c² formula
The hypotenuse always equal the c
a and b can be the other two numbers and are interchangeable
plug in 5 and 6 into a and b
(5)² + (6)² = c²
simplify
25 + 36 = c²
add
c² = 61
isolate the c, root both sides
c² = 61
√c²= √61
c = √61
Roots are Irrational numbers, and so D) irrational number should be your answer

Answer:
4
Step-by-step explanation:
-5g -6
Let g= -2
-5 (-2) -6
Multiply
10 -6
4
-31 - 4x = 5 - 5 ( 1 + 5x )
-31 - 4x = 5 - 5 - 25x
-31 - 4x = -25x
+ 31 to both sides
-4x = 6
/ -4 to both sides
x = 6/-4 = 3/-2
