Step-by-step explanation:
1. 200 = 10h
320 =
320x10 / 200
= 16h
2. 1.5 = 50m
x = 150 m
150x1.5 / 50
= 4.5cm
3. 4$ = 40balls
x = 100balls
100x4 / 40
= $10
Answer:
4 vests
Step-by-step explanation:
Larry has 9 yards of fabric, in which 2 are needed to make a vest.
Divide 9 with 2: 9/2 = 4.5
However, note that you cannot have half a vest, so you must round down.
4.5 becomes 4.
4 vests is the maximum Larry can make with 9 yards of fabric.

2 - 3i is just another of writing (2, -3) in the cartesian plane, the 2-3i however is using the "imaginary axis" for the imaginary plane, is all however the imaginary axis is simply the equivalent of the y-axis. Likewise 9+21i is just (9,21), so let's just use the distance formula.

<span>The best answer that is given to the question that is being presented above would be 68%. Since it is normally distributed and the lengths' range fall between the first lower and upper standard deviations of the distribution (which is 68%), then the answer is 68%. </span>
