1 modulo 9 is the set of numbers as follows:
(0(9) + 1), (1(9) + 1, ....)
which is:
1, 10, 19
All we have to do is divide 1000 by 9, and round down.
1000/9 = 111.111......
There are 111 numbers.
Now let us check our work.
the set is as follows:
(1,10,19, ....... (111)9 +1)
(1, 10, 19 ........ 1000)
We are within 1000.
Therefore, 111 of the 1000 smallest positive integers are congruent to 1 modulo 9.
Answer:
B
Step-by-step explanation:
Variance can be said to be a measure of dispersion for a random sample.
Variance = pq/n
When given the variance, we can find the standard deviation.
Standard deviation = √variance
= √pq/n
Answer:
no, since the numbers are mixed up both negative and positive
16 = 2/3f
16 ÷ 2/3 = f
16 × 3/2 = f
48/2 = f
24 = f
Answer:
449 per hour
Step-by-step explanation:
First of all we know the question is asking us to round to the nearest tenth and find the rate of gallons per hour.
First:
Know there are 60 minutes in one hour
Second:
Take 7.48 and multiply it by 60
Third:
This should give you---448.8
Which is correct, but we are not done
Fourth:
Round to the nearest whole number
448.8
8 is closer to 10 than it is to 1 so we add 0.2
Which gives us 449
Five:
Just add the "per hour"
Six:
Your answer is---449 per hour---
