Let's assume we were given 2 numbers: 15 and 30. Their sum is:
We want to express it as the product of GCF and another sum.
15 is divisible by: 1, 3, 5, 15
30 is divisible by: 1, 2, 3, 5, 6, 10, 15, 30
The greatest number that appears in 2 series is 15.
In this case sum of two numbers can always be written as:
Answer:a/b x c/d= a x c/b x d
Show that ac and bd are integers

Answer with explanation:</h2>
Let 
be the population mean.
By considering the given information , we have
Null hypothesis : 
Alternative hypothesis : 
Since alternative hypothesis is right-tailed , so the test is a right-tailed test.
Given : Sample size : n=16 , which is a small sample , so we use t-test.
Sample mean: 
;
Standard deviation: 
Test statistic for population mean:
i.e. 
Using the standard normal distribution table of t , we have
Critical value for 
: 
Since , the absolute value of t (2.333) is smaller than the critical value of t (2.602) , it means we do not have sufficient evidence to reject the null hypothesis.
Hence, we conclude that we do not have enough evidence to support the claim that answering questions while studying produce significantly higher exam scores.
The answer would be A.
Explanation:
If they enter with one car, that’s a price of $3 for the car alone. Because there’s also a fee for each person who enters, and there is a family of 5 who enters, x is representative of the cost for each person who enters. Therefore, there would be 5 x’s and one 3 that when solved would add up to the total of $45 they spent. That would mean A is correct because the equation would be x + x + x + x + x + 3 = 45.
Answer:
(-2,-1); (-2,-4); (0,-1); (0,-3); (-1,-4); (-1,-3)
Step-by-step explanation:
Just reflect it starting at x=-2
