Answer:
450 considering Blue appears 45 times in 100 spins.
Step-by-step explanation:
Let us assume that frequency of Blue is 45 times in 100 spins.
So we have to calculate the number of times the spinner lands on blue in 1000 spins.
It simply can be calculated as
Expected number of landing on blue:
Expected frequency = probability × number of trials
= (45/100)×1000
= 450 times
So, Expected number of landing on blue = 450

Answer:
a) ±0.73
b) ±3%
Step-by-step explanation:
One side of the right angle triangle is 12cm
The opposite angle(x) is 30 degree
Possible error = ±1degree
a) Let the hypotenus= h
h/12 = cosecx
h = 12cosecx
Differentiate h with respect to x
dh= -12cosecxcotcdx
The possible error in the angle measurement is dx
dx= ±1degree
Convert degree to radians
dx = ±1*π/180
dx = ± π/180
Put x and dx into dh
dh = -12cosec30cot30(±π/180)
= -12(2)(√3)(±π/180)
= -24√3(±π/180)
= ±24π√3/180
= ±0.73
b) To find the percentage error, recall that
dh = 12cosecx
dh = 12cosec30
dh = 12(2)
= 24
Percentage error =
(change in value/initial value) 100
Percentage error = (dh/h)100
= (±0.73/24)100
= ±0.030*100
= ±3%
