Answer:

It is a data set that can be shown as its mean after totals are multiplied. It can also be part of a question set of discrete data where all data is totaled up and further info shown to find a mean of each school. To find such mean it uses the third set of data to replace the 2nd data (students 1-25) replacing with no of students (with reference to lining up with the first list being list one hours 1, 2,3,4,5 etc. Here when say larger data says 250 students in the borough spend 1 hr we can multiple these factors to get the first multiplication value to multiply that with the totals added under each title. So it would read h x s x h(s) to find such discrete mean.

What is the answer to this equation? 3(x – 2) = 22 – x

denpristay [2]

Use the distributive property on right side and solve:

3x-6=22-x

4x-6=22

4x=28

x=7

So the solution is x=7

Hope this helped!

ASAP. Can someone help me find the percentage of these please, I can't figure it out. (Pic below)

Answer:

Interphase: 55.56%

Prophase: 27.78%

Metaphase: 8.33%

Anaphase: 5.56%

Telophase: 2.78%

Step-by-step explanation:

All you need to do is follow the instructions. To get the percentage, all you need to do is divide the part by the whole then multiply it by 100%.

$\dfrac{Part}{Whole}\times 100\%$

Now let's take your problem:

Number of cells in interphase:

20 this is the part and the whole would be the total cells, which is 36. Now we insert that into our equation:

$\dfrac{20}{36}\times 100\%=0.5556\times100\%=55.56\%$

So now we apply the same to the rest:

Prophase:

$\dfrac{10}{36}\times 100\%=0.2778\times100\%=27.78\%$

Metaphase:

$\dfrac{3}{36}\times 100\%=0.0833\times100\%=8.33\%$

Anaphase:

$\dfrac{2}{36}\times 100\%=0.0556\times100\%=5.56\%$

Telophase:

$\dfrac{1}{36}\times 100\%=0.0278\times100\%=2.78\%$

lois wants to send a box of oranges to a friend by mail. The box of oranges cannot excede a mass of 10 kg. If each orange has a

lubasha [3.4K]

Easy first cover kilograms into grams 1kg=1000g. resulting in 10,000g dividing that by the weight of the oranges getting 10,000/200=50 so the answer is 50 oranges. (assuming they all weigh the same)
