The number of people that can be safely carried in a lift depends on their mass. A lift will safely

Mathematics

Answer:

Step-by-step explanation:

If a lift will carry 8 people safely with an average mass of 75kg each we multiply to find the weight the lift can safely carry.

8 x 75kg = 600kg

If the average mass of the people is 100kg each, we divide to find the number of people it can carry. We know the lift can carry 600kg.

600kg/100kg = 6

So the lift can carry 6 people if their average mass is 100kg.

A B C D E Confirm Supplies for last year cost $1,477, which was $177 over budget. Rounded to the nearest 1%, by what percent did
Paha777 [63]
It would be over 12% (11.98375085%)

Lets break it down:

You need to find what percent 177 is of 1,477.
To do this, you need to do 177÷1,477 to get 0.1198 and so on

(To find a percent from a decimal, you move the decimal point 2 places to the right)

If you find the percent, it would be 11.98 (and so on) percent. Rounded to the nearest 1%, it would be 12%

Hope this helps!

You just discovered that you have 100 feet of fencing and you have decided to make a rectangular garden. What is the largest are
Rudik [331]
The area is:
 A = x * y
 The perimeter is:
 P = 2x + 2y = 100
 We clear y:
 2y = 100-2x
 y = 50-x
 We write the area in terms of x:
 A (x) = x * (50-x)
 Rewriting:
 A (x) = 50x-x ^ 2
 Deriving:
 A '(x) = 50-2x
 We equal zero and clear x:
 50-2x = 0
 x = 50/2
 x = 25
 Then, the other dimension is given by:
 y = 50-x
 y = 50-25
 y = 25
 Therefore, the largest area is:
 A = (25) * (25)
 A = 625 feet ^ 2
 Answer:
 
the largest area you can enclose using the materials you have is:
 
A = 625 feet ^ 2

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
