Find the distance between the two points in simplest radical form.
SCORPION-xisa [38]

Answer:

The answer is \sqrt{61}

.

Step-by-step explanation:

The distance formula:

d =  \sqrt{(x_2 - x_1)^{2} + (y_2 - y_1)^{2}  }

.

☆All we need to do is plug in!

d =  \sqrt{(x_2 - x_1)^{2} + (y_2 - y_1)^{2}  }  \\ \\  d =   \sqrt{( - 1 - 4) ^{2} + ( - 9 - ( - 3))^{2}  }  \\ d =  \sqrt{( - 5)^{2} + ( - 6) ^{2}}  \\ d  =  \sqrt{25 + 36 }  \\  d =  \sqrt{61}

alexira [117]

Answer:

There is a significant linear correlation between the two variables.

Step-by-step explanation:

Given that part time weekly earnings are

x y

 

10 93

15 171

20 204

20 156

35 261

 

 

 

Correlation 0.9199

H0: r=correlatin =0

Ha: r ≠0

(two tailed test)

r difference = 0.9199

t = r*\sqrt{(n-2)/(1-r^2)} \\=4.063

p value < 0.0001

Since p <0.05 we reject null hypothesis

There is a significant linear correlation between the two variables.
