The diameter of a volleyball is 15.5 find its radius and volume​

Mathematics
1 answer:
lilavasa [31]3 years ago
4 0

Step-by-step explanation:

diameter = 2 × radius.

15.5 = 2 × r.

r = 15.5 ÷ 2.

r = 7.75.

volume = πr²

v = π × 7.75².

v = 188.7.

I ain't confident about the volume answer but, the diameter answer is correct.

hope it helps. :)

The transitive property of equality states that:
Naily [24]

Answer: If a=b and b=c, then a=c

Step-by-step explanation:

Let be "a", "b", and "c" all real numbers, the Transitive property of equalities states that :

If a=b and b=c, then a=c

You can observe that if two numbers are equal to the same number, then all this numbers are equal to each other.

For example, applying the Transitive property of equalities to:

x+3=5 and 2x+1=5

You can equate them:

x+3=2x+1

And solve for "x":

3-1=2x-x\\\\x=2

Which of the following represents a weak positive correlation? And explain.
Soloha48 [4]

Answer:

  1. R= 0.2
  2. 2

Step-by-step explanation:

explaining the answer to 1

I'll explain everything so you understand.

The correlation coefficient tells us about the strength of the relationship between the variables. In other words, it tells us how well the data fits on the line of best fit.

So, the closer the points lie on the line of best fit the stronger the relationship and correlation.

The further the points lie from the line of best fit, the weaker the correlation

It is important to note that the correlation coefficient (r) always lies between -1 and 1.

So, the closer the value of r lies to -1 or 1 the stronger the relationship between the variables.

The closer the value of r is to 0 the weaker the relationship between the variables and the weaker the correlation.

explaining the answer to 2

the correlation coefficient (r) always lies between -1 and 1 so it can't be 2.

Hope this helps.
