Find the circumference of this circle. Round to the nearest tenth.<br><br> Area= 63.6 inches squared
Virty [35]

Answer:

C = 28.048

Step-by-step explanation:

Circumference = 2pi(r)

Area = pi(r)^2

62.6 = pi(r)^2

r^2 = 62.6/pi

r^2 = 19.926

r = 4.464

Therefore, circumference = 2pi(4.464)

= 28.048

Serggg [28]

Answer:

No.

Step-by-step explanation:

As x increases 2^x will grow faster than 5 x^2. This is because the x in 2^x is an exponent and its graph grows very steeply compared with 5x^2 , as x increases.

For example when x = 10

5x^2 = 5*10^2 = 500

2^x =  2^10 =1024

When x = 11:

5x^2 = 605

2^x = 2048 and the difference will continue to increase.

For the following paired data, (1) Calculate the correlation coefficient, r, and (2) at the 0.05 significance level, determine w
expeople1 [14]

Answer:

Linear correlation exists

Step-by-step explanation:

Given the data :

X : | 2 4 5 6

Y : | 6 9 8 10

Using technology to fit the data and obtain the correlation Coefficient of the regression model,

The Correlation Coefficient, r is 0.886

To test if there exists a linear correlation :

Test statistic :

T = r / √(1 - r²) / (n - 2)

n = number of observations

T = 0.886 / √(1 - 0.886²) / (4 - 2)

T = 0.866 / 0.3535845

T = 2.449

Comparing Pvalue with α

If Pvalue < α ; Reject H0

Pvalue = 0.1143

α = 0.05

Pvalue > α ; We reject the null and conclude that linear correlation exists
