Answer:

4.5

Step-by-step explanation:

First, you have to put them in order from least to greatest

0,2,3,4,5,6,7,9

Now we start crossing out the ends on both sides until we get to one in the middle.

2,3,4,5,6,7

3,4,5,6

4,5

Now, we will add these two and then divide them by 2

4+5=9

9÷2=4.5

Answer:

75

Step-by-step explanation:

Scores for his first tests were 65, 67, 69.

Rate of change: +2

y=2x+63; 63 is the 0th test he took, his first test was 65, so 65-2=63. 2x is the rate of change, his tests scores increase by 2 each time.

x=6, 6th test score

y=2(6)+63

y=12+63

y=75

So, on his 6th test he will get a score of 75

What is a​ placebo and why is it important?
Ksju [112]

Answer:

A placebo is a fake put into place in order to make a user believe something is happening when it is not.

Step-by-step explanation:

A placebo is a fake put into place in order to make a user believe something is happening when it is not. This is used often in medicine, where a doctor may tell a patient they are receiving treatment for some condition, but in fact they are getting nothing. Often times this can actually make a change for the patient due to simply believing they are getting treatment. The placebo effect is also used in Statistics, with 2 groups, one getting the treatment, and one simply receiving a placebo. This is helpful because it shows the effect of treatment or medication more accurately.
