Answer:
The value of given expression for x = - 10 is - 81
Step-by-step explanation:
Given expression as :
3 
x - 2 
Or, 3 + x - 2 -
Or, 
x - 
or, 
Now for x = - 10
Or, 
∴ - 76 - 5
Or, - 81
Hence The value of given expression for x = - 10 is - 81 Answer
Step-by-step explanation:
Margin of error = critical value × standard deviation
We aren't given the critical value or any information to calculate it, so we need to make some assumptions. Assuming the data set is large enough to be approximated as normal, and that the confidence level is 95%, then the critical value is 1.96.
ME = 1.96 × 9.5
ME = 18.62
You may choose to round 1.96 to 2, in which case the margin of error is:
ME = 2 × 9.5
ME = 19
You have to convert the fraction so the bottom number is 100
1900: 14/25=56/100
1910: 29/50=58/100
1920: 53/100
1930: 13/20= 65/100
1940: 3/5=60/100
Your answer would be 1930: 13/20= 60/100
