Answer:

True.

Step-by-step explanation:

We have been given a statement and we are asked to determine whether our given statement is true or false.

Statement:

A z-score of 1.0 corresponds to a value one standard deviation from the mean.

We know that z-score of a data set represents how many standard deviation a data point is above or below mean.

Since the z-score of a data set is 1.0, so it represents that the data is 1 standard deviation above mean.

Therefore, our given statement is true.

rodikova [14]

$\sf{\red{Answer}}$

$\sf{m = \frac{1}{2} }$

$\sf{\purple{Explanation}}$

$\sf{m = \frac{y_{2}- y_{1}}{m_{2} - m_{1}} }$

$\sf{m = \frac{9- 3}{7- ( - 5)} }$

$\sf{m = \frac{6}{7 + 5} }$

$\sf{m = \frac{6}{12} }$

$\sf{m = \frac{1}{2} }$

In a factory A, about 3 out of every 2,000 toys have a defect. In factory B, about 5 out of every 4,500 toys have a defect. One

gavmur [86]

Answer:

Step-by-step explanation:

Factory A proportion:

3 : 2,000

Factory B proportion:

5 : 4,500 (this can be simplified):

1 : 900

Now plug in 18,000 to each proportion:

Factory A:

x : 18,000

3 : 2,000

x = 27

Factory B:

x : 18,000

1 : 900

x = 20

Factory A had the greater amount of defects, 27

Find dy/dx by implicit differentiation and evaluate the derivative at the given point.xy = 12, (-4, -3)

mojhsa [17]

Xy=12
xdy/dx + y = 12
xdy/dx = 12 - y
dy/dx= (12-y) /x
dy/dx | x=-4 ,y=-3 = (12-(-3))/(-4)
= (12+3)/-4 = -15/4
