Answer:

y= (6/5)x-3

if you want the slope it's 6/5 and the y intercept is -3

Step-by-step explanation:

sI'm not too sure what the question so i'll just assume that you want to write this in slope intercept form

or y=mx+b

to do this all we need to do is have y be positive and by itself

to do this you can just divide both sides by -5

which gives us

y= (6/5)x-3

The slope of the equation is 6/5 and the intercept is (0,-3) and slope intercept form y=mx+b is y=6/5x -3

Simplest form of ratio 24:36:60

kumpel [21]

Answer:

2:3:5

Step-by-step explanation:

24:36:60

1) Find the greatest common factor

24 ⇒ 1, 2, 3, 4, 6, 8, 12, 24

36 ⇒ 1, 2, 3, 4, 6, 9, 12, 18, 36

60 ⇒ 1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 30, 60

Therefore, the greatest common factor is 12.

2) Divide all values by 12

24 ÷ 12 = 2

36 ÷ 12 = 3

60 ÷ 12 = 5

Therefore, the simplified form of the ratio is 2:3:5.

I hope this helps!

find the probability of at least 3 successes in a 3 trials of a binomial experiment i which the probability of successe is 50%

katrin2010 [14]

each trial is independent so do

.5 x .5 x .5 or .5^3

.125 is the probability.

The formula c = 5p + 215 relates c, the total cost in dollars of hosting a birthday party at a skating rink, to p, the number of

emmasim [6.3K]

Answer: a. p = c/5 - 43 b. 17 people

Step-by-step explanation:

c= 5p + 215

A) a said solve for p so we will solve for p in the equation.

c= 5p + 215 First Subtract 215 from both sides

-215 -215

c - 215 = 5p Now divide both sides by 5.

p = c/5 - 43

B) If c is the total cost of hosting a birthday party then we will input 300 into the equation for c and solve for p.

300 = 5p + 215 First subtract 215 from both sides

-215 -215

85 = 5p Divide both sides by 5

p = 17

This means 17 people can attend the meeting if Allies parents are willing to spend $300.

If tanA=a then find sin4A-2sin2A/ sin4A+2sin2A

anygoal [31]

Answer:

The value of the given expression is

$\frac{sin4A-2sin2A}{sin4A+2sin2A}=-a^2$

Step by step Explanation:

Given that $tanA=a$

To find the value of $\frac{sin4A-2sin2A}{sin4A+2sin2A}$

Let us find the value of the expression :

$\frac{sin4A-2sin2A}{sin4A+2sin2A}=\frac{2cos2Asin2A-2sin2A}{2cos2Asin2A+2sin2A}$ ( by using the formula $sin2A=2cosAsinA$ here A=2A)

$=\frac{2sin2A(cos2A-1)}{2sin2A(cos2A+1)}$

$=\frac{(cos2A-1)}{(cos2A+1)}$

$=\frac{(-(1-cos2A))}{(1+cos2A)}$ (using $sin^2A+cos^2A=1$ here A=2A)

$=\frac{-(sin^2A+cos^2A-(cos^2A-sin^2A))}{sin^2A+cos^2A+(cos^2A-sin^2A)}$ (using $cos2A=cos^2A-sin^2A$ here A=2A)

$=\frac{-(sin^2A+cos^2A-cos^2A+sin^2A)}{sin^2A+cos^2A+(cos^2A-sin^2A)}$

$=\frac{-(sin^2A+sin^2A)}{cos^2A+cos^2A}$

$=\frac{-2sin^2A}{2cos^2A}$

$=-\frac{sin^2A}{cos^2A}$

$=-tan^2A$ ( using $tanA=\frac{sinA}{cosA}$ here A=2A )

$=-a^2$ (since tanA=a given )

Therefore $\frac{sin4A-2sin2A}{sin4A+2sin2A}=-a^2$
