Answer: 0.02
Step-by-step explanation:
Given: Sample size : 
The population proportion 
Then, 
The formula to calculate the standard error is given by :-
Hence, the standard deviation of the sample proportions (i.e., the standard error of the proportion) is <u>0.02</u>.
We have to find 100% of the number. We can use proportion to get it
3% -----------1.5m
100% -------- x
crossmultiply now
3*x=1.5*100
3x=150 /:3 divide both sides by 3
x=50m
2. Similar situation
40% ------------1000
100% -----------x
crossmultiply
40*x=100*1000
40x=100000 /:40
x=2500 - its the answer
Answer:
$5.40
Step-by-step explanation:
First, figure out the cost of the items with tax; for Tommy we have 20*0.08 = 1.6, add that 1.6 to the 20 and his purchase is $21.6, for John we have 25*0.08 = 2, add 2 to his 25 and his purchase is $27. To find the difference we subtract 27-21.6 = 5.4 or $5.40

Answer:
C - 1 / sin^2x
Step-by-step explanation:
as csc x = 1 / sin x
so, csc^2 x = 1 / sin^ 2x
