Answer:
Step-by-step explanation:
if we tip/tax 6% of 156.67 we will do:
156.67*(6/100)=9.40 this is the amount of tip
156.67+9.40=166.07
Answer:
Step-by-step explanation:
We are looking for a new number which is 1000 more than 103.
We will get the new number by adding 1000 to 103.
We write it down as:
103+1000=1103
And finally the solution for: What number is 1000 more than 103?
is <em>1103</em> ans

D - the graph is descending best estimate answer for hour 10
The 2 marked angles add up to 180 if m and n are parallel.
I cant solve for x because the image is very unclear.
The confidence interval is
. This means that we can be 99% confident that the mean number of books people read lies between 9.15 and 11.85.
To find the confidence interval, we first find the z-score associated with it:
Convert 99% to a decimal: 0.99
Subtract from 1: 1-0.99=0.01
Divide by 2: 0.01/2 = 0.005
Subtract from 1: 1-0.005 = 0.995
Using a z-table (http://www.z-table.com) we see that this is associated with a z-score between 2.57 and 2.58. Since both are equally far from this value we will use 2.575.
We calculate the margin of error using
This means that the confidence interval is
The lower limit is given by 10.5-1.35 = 9.15.
The upper limit is given by 10.5+1.35 = 11.85
