Answer:

x = 6/3y+1

Step-by-step explanation:

x+3xy=6

Step 1: Factor out variable x.

x(3y+1)=6

Step 2: Divide both sides by 3y+1.

x(3y+1) / 3y+1

so x = 6/3y+1

1. Turn x+3y=6 into slope intercept form:

3y = 6 - x

y = 2 - 1/3x

2. The perpendicular slope is always the negative reciprocal.

-1/3 becomes 3/1

3. Find the intercept

5 = (3/1)1 +b

b = 2

Answer: y = 3x + 2, or y = 3/1x + 2

Philip and Veronica are in band together. He asked her a statistical question. Which question

Karo-lina-s [1.5K]

The answer would be D. How long are the songs you practice playing on your instrument?

Statistical questions are ones that will show variability. The first three questions will have a straight answer. The last one however will have data that varies, since most likely every song is not the same length.

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,

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