Well so 15000-2000 leaves 13000kgs of available weight allowed. Then 13000 divided by 1500 we get around 8.67 cubicmeters of gravel to be allowed to be lifted safely.

The density of a substance is defined as its mass per unit volume. In a mathematical language, this can be written as follows:
From the problem, a student is trying to calculate the density of a ball. She already knows the mass, but is facing a problem because she also needs to find the volume. From geometry, we know that the volume of a sphere is:
Since a ball is a sphere, then the student can use this formula. She just need to measure the radius of the ball and compute the Volumen, then she have to plug both the value of the mass and the value of the Volume in the equation 
. An easy way to find the radius is to take the measure of the diameter of the ball and divide that value by 2.
Answer:
This means we reject that all the three groups have same means.
Step-by-step explanation:
given that in a one-way ANOVA, we reject the statement in the null hypothesis if three treatment groups are being compared
In anova one way we compare the means of more than two groups.
The hypotheses are set up as
H0: Means of all three groups are equal against
Ha: atleast two means are different
When we find out F statistic by dividing SST by MST
we get p value.
Whenever p is less than significant level, we reject null hypothesis
This means we reject that all the three groups have same means.
Then we can go further to check up which pair is different by doing Tukey test or pairwise t test.
