12 / 14 =
(22 * 3) / (2 * 7) =
((22 * 3) : 2) / ((2 * 7) : 2) =
(12 : 2) / (14 : 2) =

vagabundo [1.1K]

The total bill (before tax and tip) = $90

0.06 x $90 = $5.4

Tip = 20% = 0.20

0.20 x $90 = $18

$90 + $18 + $5.4 = $113.4 (Answer)

Multiple Choice: A prism and a pyramid have identical bases and heights. The volume of the prism is: Twice as large as the pyram

Natali [406]

Answer:

<h3>Three times as large as the pyramid's volume</h3>

Step-by-step explanation:

Let the volume of prism be Vp

Let the Volume of pyramid be Vy

Vp = Base Area * Height .... 1

Vy = Base * Height/3 ....2

From 2;

Vp = BH/3

BH = 3Vy

Since Vp = BH, then;

Vp = 3Vy

This shows that the volume of prism is three times as large as pyramids volume

A box of candy hearts contains 52 hearts, of which 19 are white, 10 are tan, 7 are pink, 3 are purple, 5 are yellow, 2 are orang

laiz [17]

Answer-

a. Probability that three of the candies are white = 0.29

b. Probability that three are white, 2 are tan, 1 is pink, 1 is yellow, and 2 are green = 0.006

Solution-

There are 19 white candies, out off which we have to choose 3.

The number of ways we can do the same process =

$\binom{19}{3} = \frac{19!}{3!16!} = 969$

As we have to draw total of 9 candies, after 3 white candies we left with 9-3 = 6, candies. And those 6 candies have to be selected from 52-19 = 33 candies, (as we are drawing candies other than white, so it is subtracted)

And this process can be done in,

$\binom{33}{6} = \frac{33!}{6!27!} =1107568$

So total number of selection = (969)×(1107568) = 1073233392

Drawing 9 candies out of 52 candies,

$\binom{52}{9} = \frac{52!}{9!43!} = 3679075400$

∴P(3 white candies) = $\frac{1073233392}{3679075400} =0.29$

Total number of ways of selecting 3 whites, 2 are tans, 1 is pink, 1 is yellow, and 2 are greens is,

$\binom{19}{3} \binom{10}{2} \binom{7}{1} \binom{5}{1} \binom{6}{2}$

$=(\frac{19!}{3!16!}) (\frac{10!}{2!8!}) (\frac{7!}{1!6}) (\frac{5!}{1!4!}) (\frac{6!}{2!4!})$

$=(969)(45)(7)(5)(15)=22892625$

Total number of selection = 3 whites + 2 are tans + 1 is pink + 1 is yellow + 2 greens = 9 candies out of 52 candies is,

$\binom{52}{9}=\frac{52!}{9!43!} =3679075400$

∴ P( 3 whites, 2 are tans, 1 is pink, 1 is yellow, 2 greens) =

$\frac{22892625}{3679075400} = 0.006$
