Answer:

We know the following information:

Alan is conducting an experiment to determine whether a new medication is effective in reducing coughing.

Alan finds 2000 volunteers with coughing issues and divides them into two groups.

The control group does not receive any medication; the treatment group receives the medication. The patients in the treatment group show reduced signs of coughing.

Therefore, Alan can conclude that the new medication is effective in reducing coughing.

Alan can say that the medicine given to people most likely worked as the treatment group showed signs of reduced coughing.

When Louisa arranges her pennies into a rectangle with two equal rows, three equal rows, four equal rows, or six equal rows, she
kodGreya [7K]

Answer:

37

Step-by-step explanation:

The answer must be (a multiple of 2, 3, 4 and 6) + 1, and (a multiple of 5) + 1, because 1 or 2 coins were left over when dividing by 2, 3, 4, 6 or 5.

Let's look at the lowest common multiples of 2, 3, 4, 6:

Prime factorisation:

2 = 2

3 = 3

4 = 2 * 2

6 = 2 * 3

therefore, the lowest common multiple is 2 * 2 * 3 = 12

Let's look at the answers that this would give us (ie multiples of 12):

12 + 1 = 13 <-- this would work, but 11 (ie two less than 13) is not a multiple of 5

12 * 2 + 1 = 25 <-- 23 is not a multiple of 5 either

12 * 3 + 1 = 37 <-- 35 (two less than 37) is a multiple of 5 :)

therefore 37 is our answer since it is one more than a multiple of 12 (ie 36) and two more than a multiple of 5 (ie 35)

Suppose a principal amount of $7500 was invested at an interest rate of 6%. How long did it take to reach $10650?
Oliga [24]

Based on the information how long did it take to reach $10650 is 7years.

Given:

Principal=$7,500

Rate=6%

Amount=$10650

Time=?

Simple Interest(SI)=A-P

=$10650-$7500

=$3150

Time=(100×SI)/(p×r)

T=(100×3150)/(7500×6)

T=315,000/45,000

T=7 years

Inconclusion how long did it take to reach $10650 is 7years.
