1 answer:

8 0

If these are all separate answers, then: y=3r-1

Substitute r for the value it's asking for.

R=-1
y=3(-1)-1
(Answer) y=-4

R=-8
y=3(-8)-1
y=-24-1
(Answer) y=-25

R=-4
y=3(-4)-1
y=-12-1
(Answer) y=-13

R=2
y=3(2)-1
y=6-1
(Answer) y=5

R=6
y=3(6)-1
y=18-1
(Answer) y=17

A gumball machine contains 300 grape flavored balls, 400 cherry flavored balls, and 500 lemon flavored balls. What is the probab

Svet_ta [14]

Answer:

Pr(of getting 1grape ball, 1 cherry ball and 1 lemon ball) =0.20832

Step-by-step explanation:

Let the grape falvored ball be represented by G,

Cherry flavored balls be C

Lemon flavored balls be L

the possible order of picks for getting 1grape ball, 1 cherry ball and 1lemon ball are; GCL or GLC or CGL or CLG or LGC or LCG

Pr(of getting 1grape ball, 1 cherry ball and 1 lemon ball)

= Pr(GCL) or Pr(GLC) or Pr(CGL) or Pr(CLG) or Pr(LGC) or Pr(LCG)

with replacement we have;

Probability = $\frac{number of required outcomes}{number of possible outcomes}$

= $\frac{300}{1200}*\frac{400}{1200}*\frac{500}{1200} +\frac{300}{1200}*\frac{500}{1200}*\frac{400}{1200} +\frac{400}{1200}*\frac{300}{1200}*\frac{500}{1200} \\ \\+\frac{400}{1200}*\frac{500}{1200}*\frac{300}{1200} +\frac{500}{1200}*\frac{300}{1200}*\frac{400}{1200} +\frac{500}{1200}*\frac{400}{1200}*\frac{300}{1200}$

= 0.03472 + 0.03472 +0.03472 + 0.03472 + 0.03472 + 0.03472

=0.20832

What is the parent function of g(x) = 3cos (x + 180°) + 1

nexus9112 [7]

The parent function of the function g(x) = 3cos (x + 180°) + 1 is f(x) = cos(x)

<h3>What are parent functions?</h3>

Parent functions are the basic function that represents the entire family of that function family

<h3>How to determine the parent function?</h3>

The function is given as;

g(x) = 3cos (x + 180°) + 1

As a general rule, the parent function of any function is the basic equation of the function family

The basic equation of the function g(x) = 3cos (x + 180°) + 1 is f(x) = cos(x)

Hence, the parent function of the function g(x) = 3cos (x + 180°) + 1 is f(x) = cos(x)

Tell whether lines parallel perpendicular neither y=-3x+7 -2x+6y=3

Alexus [3.1K]

Hey there!!

Hmmm you seem familiar :D

Okay let's get started!!!! Okay so remember that if two lines are parallel then the slopes must be exactly the same (ex: -4 and -4) if two lines are perpendicular then the slopes are negative reciprocals (ex: -4 and 1/4)

y = -3x + 7 -2x + 6y = 3
y = (x/3) + 1/2

So these two are perpendicular since the slopes negative reciprocals

y = (x/5) + 6 -2x + 10y = 5
y = (x/5) + 1/2

So these lines are parallel since the slopes are exactly equal

I hope this helps!
