The mean of a set of twelve numbers is 5.5. The mean of another set of eight numbers is k. The mean of the combined set of twenty numbers is 8.5. Find the value of k.Can you please help me

Answers

mean is (sum of the values of the numbers in the set)/(how many numbers are in the set)


first bit
mean of 12 numbers is 5.5 is the same as
(12 numbers)/12=5.5

the second bit
mean of 8 numbers is k
(8 numbers)/8=k

(12numbres+8numbers)/20=8.5

interesting
one way is to solve the first and second equations for 12numbers and 8numbers

(12numbers)/12=5.5
times 12 both sides
12numbers=66

(8numbers)/8=k
multiply 8 both sides
8numbers=8k
input

(66+8k)/20=8.5
mulitply both sides by 20
66+8k=170
minus 66 both sides
8k=104
divide 8 both sides
k=13


k=13
k= 13.

You do (8.5 X 20) - (5.5 X 12), which is equal to 170 - 66 = 104
104 divided by 8 equals 13

Really confused with this problem. It would be great if someone could help

A cartoon lasts 18 minutes.How many seconds is the cartoon?

what is Unitary Method?

The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.

For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.

12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.

As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.

This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.

Given:

A cartoon lasts 18 minutes.

We know, 1 minute  = 60 seconds

So, 18 minutes= 60  x 18

                       = 1080 seconds

Hence, the cartoon lasts 1080 seconds.

18 Minutes
So 1 minute equals to 60 seconds.
So 60 times 18 equals 1,080.

each evening, Marisol spend at least twice as much time reading as she spends doing homework. If Marisol works on her homework for 42 minutes, how much time can she spend reading?

Answers

To get the result we can use knowledge that reading is 2 times longer than HW.
To find this value we just have to multiply 42 times 2 so
40*2=80
Its 1 hour and 20 min - its the result
multiply 42 times 2 and your answer will be 84

Use rounding or compatible numbers to estimate the sum 302+412

Answers

i think it would be 710 because you can round the 302 to 300 and then 412 to 410 and then you add the but it asks to estimate so it would probably be 700   
well i just looking at the first numbers of each one and added those up that became 700 and since the numbers behind them arent so big it rounds out to 700:))
