The mean weight for 5 friends is 56.6kg . if 2 more people weighting 62 and 64.5kg join them , what will be their new mean weight

58.5kg

Step-by-step explanation:

=56.6kg×5

=283kg(5 friends total weight)

=283kg+62kg+64.5kg÷7

=58.5kg

Hope this will help ya!

58.5kg

Step-by-step explanation:

To calculate mean, you add all the values, and divide the sum by the number of values. So, to find the total weight, you must multiply because multiplication is the inverse operation. 56.6 * 5= 283 kg. Two more people join, so you must add their weight to the total weight. 283 + 64.5 + 62= 409.5

Now, there are a total of 7 people (5+2=7). SO to find the mean, divide the total weight (409.5) by the total number of people (7) to find the mean.

409.5 / 7= 58.5

plants store their excess carbohydrate in the form of starch so that it could be used as energy source later on. the excess carbohydrate is converted into starch in the plastid i.e. chloroplast & this process occurs in the presence of sunlight. it is an insoluble polymer of glucose which gets stored in cell organelles named as amyloplasts. in some plants, starch is also stored in roots and embryos.

the answer would be 1 1/72

step-by-step explanation:

you can rewrite the equation by separating the parts and then solving individually:

10-9=1

1/8 - 1/9=

find l c d and then combine:

1 1/72
