-3(6r + 1) = 14 - r; -3×6r= -18r; -3×1= -3; -18r - 3 = 14 - r; -r + 18r= 17r;
17r - 3 = 14; 14+3= 17; 17r = 17; 17 ÷ 17= 1; r = 1
The answer is r = 1.

Hope this helps :)

You first have to do distributive property to get -18r-1=14-r, now get teh smallest r to the other side, in this case add 1r to both sides to get -17r=14, now add 3 to both sides to get -17r=17, now divide by -17 to leave r by itslef and get teh answer of r=-1

Hope this helps

Given: △RST ~ △VWX

tatiyna

Answer:

Given

Step-by-step explanation:

Given that: △RST ~ △VWX, TU is the altitude of △RST, and XY is the altitude of △VWX.

Comparing △RST and △VWX;

TU ~ XY (given altitudes of the triangles)

<TUS = <XYW (all right angles are congruent)

<UTS ≅ <YXW (angle property of similar triangles)

Thus;

ΔTUS ≅ ΔXYW (congruent property of similar triangles)

<UTS + <TUS + < UST = <YXW + <XTW + <XWY = $180^{0}$ (sum of angles in a triangle)

Therefore by Angle-Angle-Side (AAS), △RST ~ △VWX

So that:

$\frac{TU}{XY}$ = $\frac{US}{YW}$ (corresponding side length proportion)

A community college has 150 word processors. The probability that any one of them will require repair on a given day is 0.025. T

Volgvan

Answer:

Binomial Distribution

Step-by-step explanation:

In this case there are only two possible outcomes that is either the processor requires repair or does not require.

In such cases binomial distribution is beneficial to use.

Binomial Distribution is simply the probability of failure or success in an experiment that is repeated multiple times.

for binomial to be used following three conditions are to be used:

1. Fixed number of trails

2. Each trial or observation is independent

3. probability of success is exactly same
