On a recent quiz, the class mean was 70 with a standard deviation of 2.1. Calculate the z-score (to 4 decimal places) for a pers
Igoryamba
The equation to find a z score is (x- mean)/(standard deviation)

So, in this case the equation would be
(76-70)/(2.1)

For,
X=76
Mean=70
Standard Deviation= 2.1

After solving we find that the z score equals 2.85714

or

2.8571

Item 6 Your city is represented in a coordinate plane where each unit represents 1 kilometer. The library is at (−3, −3), the po
Snezhnost [94]

We know, shortest distance between two points (x_1,y_1) and (x_2,y_2) is :

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

So, distance between house and library is :

d_1=\sqrt{(-5-(-3))^2+(2-(-3))^2}\\\\d_1=5.39\ km

Distance between library and post office :

D=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}\\\\D=\sqrt{(-3-2)^2+(-3-2)^2}\\\\D=7.07\ km

Distance between post office and house :

D=\sqrt{(2-(-5)^2)+(2-2)^2}\\\\D=7\ km

Therefore, minimum distance that you can ride your bike is (5.39+7.07+7) km = 19.46  km.

Hence, this is the required solution.

= (6)(y + 3)
= (6)(y) + (6)(3)
= 6y + 18(answer)

Hope I helped!
