40.

45 seconds is 3/4 of a minuet so after 45 seconds you have done 30/40 push ups after a minute you have done 40/40= one minuet.

40.

#2 Find the slope given the points (6,-12) and (15,-3)*

castortr0y [4]

Greetings :)

To find slope of two points we will need to use this equation: $\frac{y^2-y^1}{x^2-x^1}$

$x^1$ $x^2$ $y^1$ $y^2$

( 6 , -12 ) ( 15 , -3 )

Now let's replace the equation with the numbers. (it will be a fraction).

$\frac{-3-(-12)}{15-12}$ = $\frac{9}{9}$

The equation equals 9 over 9, which also equals 1.

The slope of the line is 1.

A group of dental researchers are testing the effects of acidic drinks on dental crowns. They have five containers of crowns lab

mestny [16]

Answer:

$\begin{array}{cccccc}{x} & {V} & {W} & {X} & {Y} & {Z} & P(x) & {0.20} & {0.20} & {0.20} & {0.20} & {0.20} \ \end{array}$

Step-by-step explanation:

Given

$S = \{V,W,X,Y,Z\}$

$n(S) = 5$

Required

The probability model

To do this, we simply calculate the probability of each container.

So, we have:

$P(V) = \frac{n(V)}{n(S)} = \frac{1}{5} = 0.20$

$P(W) = \frac{n(W)}{n(S)} = \frac{1}{5} = 0.20$

$P(X) = \frac{n(X)}{n(S)} = \frac{1}{5} = 0.20$

$P(Y) = \frac{n(Y)}{n(S)} = \frac{1}{5} = 0.20$

$P(Z) = \frac{n(Z)}{n(S)} = \frac{1}{5} = 0.20$

So, the probability model is:

$\begin{array}{cccccc}{x} & {V} & {W} & {X} & {Y} & {Z} & P(x) & {0.20} & {0.20} & {0.20} & {0.20} & {0.20} \ \end{array}$

Find YW. YW = _<br><br> I just need the answer for YW no explanation needed.

KATRIN_1 [288]

Answer:

$YW=20\ units$

Step-by-step explanation:

we know that

In a parallelogram the diagonals bisect each other

The figure XYZW is a parallelogram

VW=VY

VX=VZ

<em>Find the value of b</em>

VW=VY

substitute the given values

$b+8=5b$

solve for b

$5b-b=8\\4b=8\\b=2$

Find the length of YW

$YW=YV+VW$ ----> by addition segment postulate

$YW=5b+b+8$

substitute the value of b

$YW=6(2)+8=20\ units$
