A Demolition ball weigths 2 tons . what is the weigtht in ounces?also what is a demolition ball?

kkurt [141]

Answer:

64,000 oz

Step-by-step explanation:

A demolition (wrecking) ball is a relatively large dense mass, often spherical, typically swung from a crane, used to demolish buildings or other structures.

We assume you want to convert from a US short ton (2000 pounds) to Avoirdupois ounces (16 ounces per pound).

Then your ball's weight is ...

(2 tons)(2000 lb/ton)(16 oz/lb) = 64,000 oz

Find the slope of the line that passes through each pair of points (8,2) (8, -1)

mash [69]

Answer:

Undefined

Step-by-step explanation:

Use the following formula to solve for slope:

$\frac{y_2-y_1}{x_2-x_1} =m$

$m=\frac{(-1)-2}{8-8}$

$m=\frac{-3}{0}$

The equation is not a function and therefore the slope is undefined because there are multiple y values for a single x value.

ATCs are required to undergo periodic random drug testing.

aleksandr82 [10.1K]

Answer:

The responsess to the given question can be defined as follows:

Step-by-step explanation:

$P(medication\ used) = 0.007 \\\\P( drug \not\ used ) = 1 - 0.007 = 0.993\\\\P(test\ positive | medication \ used) = 0.96 \\\\ P(test \ negative | medication \ used) = 1 - 0.96 = 0.04\\\\$

$P(Point | Non-used\ medication )=0.93\\\\ P(Point |No\ medication ) = 1 - 0.93 = 0.07$

As per the given info we draw the tree diagram which is defined in the attachment file.

$P ( test \ is\ positive ) = P( medication \ used ) \times P( Test \ positive | medication \ used ) + P( medication not \ used ) \times P( Test\ positive | medication \ not \ used )$

$= ( 0.007 \times 0.96 ) + ( 0.993\times 0.07 )\\\\= 0.0762$

$P( medication \ used | test\ positive )= \frac{\textup{P( medication used ) *P( Test positive given medication used )}}{\textup{P( medication used )}}$

$= \frac{( 0.007\times 0.96 )}{0.0762}\\\\= 0.0882$
