Answer:
Step-by-step explanation:
Mean= 10+2+5+2+6+7+9+2+3/9
=46/9 = 5.11
Arrange in Ascending order:
2,2,2,3,5,6,7,9,10
Mode = 2 ( that occurs most number of times)
Median = 5 ( median is the middle term)
Answer:
Step-by-step explanation:
The area of a triangle is:
A=05*b*h
b= base = x
h = height = x-12
A = (1/2)(x)(x-12)
Answer:
See explanation.
Step-by-step explanation:
2) Your written answer is correct, y = x +4
3) Slope of perpendicular line: 5/2
y=mx+b
4 = (5/2)(4) + b
4 = 10 + b
b = -6
So, y=(5/2)x - 6
4) Slope of perpendicular line: 1
y=mx+b
5 = (1)(4) + b
5 = 4 + b
b = 1
So, y = x + 1
7) Slope of perpendicular line: 3/4
y=mx+b
4 = (3/4)(4) + b
4 = 3 + b
b = 1
So, y = (3/4)x + 1
8) Slope of perpendicular line: 1/4
y=mx+b
-2 = (1/4)(0) + b
b = -2
So, y = (1/4)x - 2
Answer:
she can make a maximum of 4 bags.
peach bags containing 7 pencils and 18 erasers.
Step-by-step explanation:
find all the factors each numbers are divisible by:
28 => 1, 2, 4, 7, 14, 28
72 => 1, 2, 3, 4, 8, 9, 18, 24, 36, 72
choose the maximum common denominator.
Answer:
280m
Step-by-step explanation:
Work rate would be (210m)/(45people)(60days)=7/90 m/(people)(day)
7/90 m/(people)(day) * 72people * 50days =280m
