Exponents are used as a shorthand notation for repeated multiplication.
Answer: 99% confidence interval would be (0.13,0.26).
Step-by-step explanation:
Since we have given that
Sample size n = 1418
x = 354
So,
At 99% level of significance, z = 2.58
So, interval would be
Hence, 99% confidence interval would be (0.13,0.26).
Answer:
Step-by-step explanation:
The standard form equation for a circle is
where h and k are the coordinates of the center. Our center is given as (-6,7) and the radius is given as 9, so that information fits into our standard form like this:
and simplified, it looks like this:
That's choice C
Decimal : 1.5
Percent : 150%
Answer:
x=8
Step-by-step explanation:
You move all terms that don't contain x to the right side and solve.
3x-6=18
