mortar is made by mixing water cement and sand in the following ratio 1 : 2 : 3 . how much of each component is needed to make 3kg of mortar

To make 3 kg of water, we need

0.5 kg water

1 kg cement

1.5kg sand

Step-by-step explanation:

Here, we want to calculate the mass of each component needed to make 3 kg of mortar

We work with the ratio

Total ratio is:

1 + 2 + 3 = 6

water

1/6 * 3kg = 0.5 kg

cement

2/6 * 3 kg = 1 kg

sand

3/6 * 3 = 1.5 kg

for finding the midpoint of any given 2 pair of points simply add the respective x coordinates with other x coordinate and the y coordinate with other y coordinate and divide them by 2

in your question it will be :

(3+1)/2 for the x coordinate of mid point i.e 2

[8+(-4)]/2 for the y coordinate of midpoint i.e 2

so coordinates of mid point of points (3,8) and (1,-4) will be (2,2)

the median here is 25. your lowest value is 14 and highest value is 48. to find the third quartile, find the medium number in between 25 and 48 which would be 42 i believe.
