Two processes in a manufacturing line are performed manually: operation A and operation B. A random sample of 50 different assem

MArishka [77]

Answer:

3.06

Step-by-step explanation:

The correct answer is - 3.06

Reason -

For sample A :

mean, $\bar{x_{1} }$ = 8.05

Standard deviation, $\sigma_{1}$ = 1.36

Size, $n_{1}$ = 50

For sample B :

mean, $\bar{x_{2} }$ = 7.26

Standard deviation, $\sigma_{2}$ = 1.06

Size, $n_{2}$ = 38

Now,

$\bar{x_{1} }$ - $\bar{x_{2} }$ = 8.05 - 7.26 = 0.79

Standard deviation error, SE = √( $\sigma_{1}$ ²/ $n_{1}$ + $\sigma_{2}$ ²/ $n_{2}$ ) = 0.2580

Now,

Z-statistic = ( $\bar{x_{1} }$ - $\bar{x_{2} }$ )/ SE

= 0.79/0.2580

= 3.06

⇒Z-statistic = 3.06

Answer: 100 rides are needed to break even.

Step-by-step explanation:

C(x)=15x+2000 - x is the number of rides.

R(x)=35 x , where x is the number of rides

35x=15x+2000

35-15x=2000~subtract 15x from both sides~

20x=2000 ~simplify~

x=2000/20 ~dividing both sides by 20~

x=100

The base of a rectangular prism has an area of 13 2/3, and the height of the prism is 8 5/6. What is the volume of the prism? Be

Fed [463]

Answer:

120 $\frac{13}{18}$

Step-by-step explanation:

The formula for finding the volume of a prism is:

V = Bh

You have to convert 13 $\frac{2}{3}$ into an improper fraction, like so:

$\frac{41}{3}$

Convert the other:

$\frac{53}{6}$

Multiply:

$\frac{41}{3}$ · $\frac{53}{6}$ = $\frac{2173}{18}$

Convert to mixed fraction:

120 $\frac{13}{18}$
