If i raked 5/12 of grass and someone else raked 4/9 how much more needs to be raked

1 answer:

5 0

To solve this problem, you can subtract the sum of 5/12 and 4/9 from 1. To find the sum of 5/12 and 4/9, you need to make them have common denominators.
5/12*3/3=15/36
4/9*4/4=16/36

Now add the two fractions.
15/36+16/36=31/36

Lastly, subtract the sum from 1.
1-31/36=5/36.

Step-by-step explanation:

Note that 92 and 128 are 3 standard deviations from the mean

The emperical rule or the 68–95–99.7 rule states that 68% of outcomes are wihtin 1 standard deviation from the mean

95% of outcomes are within 2 standard deviations from the mean

99.7% of outcomes are within 3 standard devations from the mean

This is 3 standard deviations so the answer is 99.7

olchik [2.2K]

Answer:

$V = \frac{4}{3} \pi R^{3}$ and

$v = \frac{4}{3} \pi r^{3}$

Step-by-step explanation:

Dawn wants to compare the volume of a basketball with the volume of a tennis ball.

Now, if the radius of the basketball is R and that of the tennis ball is r, then the formula that can be used to determine the volume of each ball will be

$V = \frac{4}{3} \pi R^{3}$ and

$v = \frac{4}{3} \pi r^{3}$

Now, dividing V by v we can compare the volume of the basketball and the tennis ball. (Answer)
