The cactus one I think is 0.875
1st, find the mean of all values. 1+2+3+4=10 10/4=2.5 The mean is 2.5.
2nd, find the distance of each value from the mean. So 2.5-1=1.5; the distance between 1 and 2.5 is 1.5. Repeat it for all of them, and you get 1.5, .5, .5, and 1.5.
3rd, you take each distance and find the mean. 1.5+.5+.5+1.5=4 4/4=1 The mean deviation is 1.
Answer:
Each car magnet costs $4.95 and each pom-pom costs $0.425
The club spent $495 on 100 car magnets and $85 on 200 pom-poms.
Step-by-step explanation:
I guess that we have to calculate the price of pom-poms and how much money was spent purchasing car magnets and pom-poms.
x + y = 300
2x = y (now we replace y)
x + 2x = 300
3x = 300
x = 100
The club purchased 100 car magnets and 200 pom-poms.
To determine the price of each pom-pom:
($4.95 x 100) + 200P = $580
$495 + 200P = $580
200P = $85
P = $0.425
Answer:
9, 7,-8.3,>
Step-by-step explanation:
5)-3 is marked exactly 3 units to the left of origin 0.
(since negative sign we mark on left of 0)
6) |-9| = absolute value of 9 = 9
7) y-11=-4
Add 11 to both the sides
WE get y =7 is the solution
8) a + b when a = 2.5 and b = -10.8.
= 2.5+(-10.8) = -(10.8-2.5) = -8.3
9) 0.4 is positive hence lies to the right of origin.
Partition the space between 0 and 1 into 10 equal subparts and mark 4th subdivision to get 0.4
10) -1.8>-2.5
