Just distribute the 3. 3(x + 4y) = 3x + 12y
3x + 12y is the answer.
Hi there!
Inequality:
25 - 0.75x <= 13
Since x is the amount of MP3 downloads he can buy and each CD costs 0.75 dollars, and since the total price spent needs to be less than 13 dollars and the total amount of money he has is 25 dollars, this is the answer.
Hope this helps!
Answer: 
Step-by-step explanation:
- A null hypothesis is a type of hypothesis that is used in statistics that assumes there is no difference between particular characteristics of a population wheres the alternative hypothesis shows that there is a difference.
Given: A 37 bag sample had a mean of 421 grams.
Let 
be the population mean.
Then, the null hypothesis would be:
whereas the alternative hypothesis would be:
BC IS 36 because when you compare the smaller triangle to the bigger one and the other side of the smaller triangle is multiplied by three to get to fifteen so 12 times 3 is correct answer 36
You can express 0.000036 as 3.6 × 10^-5 (we move the decimal 5 places left)
Then we find 3.6 × 10^-5 × 20.5 × 10^7
The exponents add to become just 10^2.
3.6 × 20.5 = 73.8
73.8 × 10^2 is our answer...
In proper scientific notation, this is 7.38 × 10^3. (the left # should be <10)
In standard notation, this is 7380. (we move the decimal 3 places right)
