Spotlight Dance increased the number of dancers on its competition team. Last

Mathematics
1 answer:
Nana76 [90]3 years ago
3 0

Answer:

80%

Step-by-step explanation:

To find percentage increase, we use the following formula:

Percentage Increase = \frac{New-Old}{Old}*100

Here

New means the latest value (which is 18 dancers)

Old means the previous value (which is 10 dancers)

The Multiplication by 100 is to convert the decimal answer to percentage.

So, we have:

New = 18

Old = 10

Now we substitute and find:

\frac{New-Old}{Old}*100\\\frac{18-10}{10}*100\\\frac{8}{10}*100\\80

So, there was an increase of 80%

Aside from that, the only number within the range provided that meets all requirements is 2.

Given the table :

Source of Variation - - SS - - - df - - - MS - - - - F

Regression - - - - - -3177.17 - - -2 - - 1588.6

Residual - - - - - - - - ______ --17 - - -17.717

Total - - - - - - - - - - 3478.36 - - 19

Calculate the SSR, Sum of Square residual

The Sum of Square RESIDUAL (SSR), Mean Square Residual (MSR) and Degree of Freedom RESIDUAL (DFR) are related by the formular :

MSR = SSR / DFR

Hence,

SSR = MSR × DFR

Fr the table ;

MSR = 17.717 ; DFR = 17

SSR = (17.717 × 17)

SSR = 301.189

A cylinder has a height of 6 millimeters and a radius of 4 millimeters. What is its volume? Use ​ ≈ 3.14 and round your answer t
netineya [11]

Answer:

V=301.44\ \text{mm}^2

Step-by-step explanation:

Given that,

Height of the cylinder, h = 6 mm

Radius of the cylinder, r = 4 mm

We need to find the volume of the cylinder. The formula for the radius of the cylinder is given by :

V=\pi r^2 h

Putting given values,

V=3.14\times (4)^2 \times 6\\\\V=301.44\ \text{mm}^2

So, the volume of the cylinder is 301.44\ \text{mm}^2.
