Answer:

Max

Step-by-step explanation:

Max percentage improvement in the first exam = (\frac{6}{20} ×100) %

=\frac{600}{20}%

= 30%

Maria percentage improvement in the first exam =(\frac{30}{90} ×100)%

= \frac{3000}{90}

= 33.3333333333 Round 33.33%

Hence, 30% < 33.33%

Therefore, Max showed less improvement.

A case in riverhead, new york, nine different crime victims listened to voice recordings of five different men. all nine victims
Alexus [3.1K]

the complete question in the attached figure

1) Find the probability that all nine victims would select the same person. You should enter your answer as a decimal, not as a percent. Do not round, as your answer should be a terminating decimal.

P=(1/5)*(1/5)*(1/5)*(1/5)*(1/5)*(1/5)*(1/5)*(1/5)*(1/5)=0.000000512

2) what is the probability that the first victim picks SOMEONE? ANYONE? 

P=(1/5)=0.20  ---------------- > 20%

3) Now let’s look at victim #2. What is the probability that they pick the same person as victim #1?

P=(1/5)*(1/5)=0.04 --------------> 4%

4) Now let’s look at victim #3. What is the probability that they pick the same person as victim #1?

P=(1/5)*(1/5)*(1/5)=0.008 --------------> 0.8%

5) Now let's look at victim #9. What is the probability that they pick the same person as victim #1? 

P=(1/5)*(1/5)*(1/5)*(1/5)*(1/5)*(1/5)*(1/5)*(1/5)*(1/5)=0.000000512

6) Once you find all those probabilities, what rule would apply?

the probability is given by (1/5)^n

n=number of victims that pick the same person---------> in this problem = 9

P=(1/5)^9= 0.000000512

How many solutions does the equation 4n + 6 = 4 + 2 + 4n have?
lara31 [8.8K]
4n+6=4+2+4n, well first combine like terms, 4n+6=6+4n and those are exactly the same, there's no magical n that can make 4n+6 not equal 4n+6, so <span>many

ahrayia [7]
1.30(2) + X = 6.10
This would be one of a few equations to do. 1.30(2) represents the cartons of eggs which are each 1.30. the X will represent the price of pancake mix and the total is 6.10.

Make x the subject! urgent help
Serhud [2]

Answer:

x =  \frac{n}{b -  {t}^{2} }

Step-by-step explanation:

I supposed that is a "n".

Steps as below:

{t}^{2}  = b -  \frac{n}{x}  \\ b -  \frac{n}{x}  =  {t}^{2}  \\  -  \frac{n}{x}  =  {t}^{2}  - b \\  \frac{n}{x}  =  - ( {t}^{2}  - b) \\  \frac{n}{x}  = b -  {t}^{2}  \\ n = x(b -  {t}^{2} ) \\ x(b -  {t}^{2} ) = n \\ x =  \frac{n}{b -  {t}^{2} }
