Answer:
Step-by-step explanation:
Assuming width=diameter
diameter/2=radius
area=hpir^2
w=d=2
d/2=2/2=1=r
h=6
area=6pi1^2
area=6pi1
area=6pi
aprox pi=3.141592
area=18.85 cm³
Answer:
D
Step-by-step explanation:
We calculate the z-score for each
Mathematically;
z-score = (x-mean)/SD
z1 = (1.9-2.1)/0.2 = -1
z2 = (2.3-2.1)/0.2 = 1
So the proportion we want to calculate is;
P(-1<x<1)
We use the standard score table for this ;
P(-1<x<1) = P(x<1) -P(x<-1) = 0.68269 which is approximately 68%
Answer:
The pedals
Step-by-step explanation:
A tricycle requires 3 tires, 1 frame, and 2 pedals.
Divide all the amounts by the amounts needed for one tricycle.
270/3=90
90/1=90
170/2=85
The pedals can only be assembled onto 85 tricycles while everything else can be assembles into 90 tricycles.
