Answer:

Mean is 5.

Step-by-step explanation:

We have been given the information to find mean

We have formula for $mean=\frac{total number of observations}{number of observations}$

Here, we have given:

Number of sites 15 and

total number of shield darters 75

On substituting the values in the formula we get

$Mean=\frac{75}{15}=5$

What is the volume of a cone with a diameter of 30 feet and a height of 600 feet? Use 3.14 for tt

Tomtit [17]

Answer:

the volume is about 1884

Step-by-step explanation:

v of cone= 1/3(pi)r^2h

diameter to radius is 30=5.477225575051661

so 1/3(3.14)5.477225575051661^2(60)

=1/3(3.14)30(60)

=1/3(5652)

=1884

ON A TIME LIMIT PLS HELP!!!! thank youu

Slav-nsk [51]

Answer:

RQS=110

TQS=70

Step-by-step explanation:

(12x+2)+(7x+7)=180

The two equations added together give us a straight line which is angle 180

19x + 9 = 180

19x = 171

We solve for x

x = 9

Now that we have x we plus in to each equation

RQS= (12(9)+2)

= 110

TQS=(7(9)+7)

=70
