Y = -3. Yeah this can be hard at first but you'll get the hang of it, its simple once u have that clicking moment.
What the goal is is to get y by itself, right? Then u would have y = blank and thats what u need because ur trying to find y. So to get y alone and have that y = blank, u can "balance the equation." That means if u add something on the left side of the equation (before the equal sign) u have to add it to the right. Same with subtraction. In this equation, u would subtract 6 from both sides so there would be no 6 left on the left and a 6 on the right instead. ask me questions if u need more help! :)

Expand ( 2 − x ) 5 and identify each part of the expression.

dimaraw [331]

You use distributive property. So (5 x 2)-(5 x x)= 10 - 5x.

What are the relative frequencies, to the nearest hundredth, of the rows of the two way table?

Nookie1986 [14]

Answer: A B

Group A 0.25 0.75

Group B 0.45 0.55

Step-by-step explanation:

Since we have given that

Number of people of A in Group A = 15

Number of people of B in Group A = 45

Number of people of A in Group B = 20

Number of people of B in Group B = 25

Total number of people in Group A = 15+45 = 60

Total number of people in Group B = 20+25 = 45

So, Relative frequencies will be given below:

Relative frequency of A in Group A is given by

$\frac{15}{60}=0.25$

Relative frequency of B in Group A is given by

$\frac{45}{60}=0.75$

Relative frequency of A in Group B is given by

$\frac{20}{45}=0.45$

Relative frequency of B in Group B is given by

$\frac{25}{45}=0.55$

Hence, A B

Group A 0.25 0.75

Group B 0.45 0.55

Find the probability that a randomly selected point within the circle falls in the white area

MrMuchimi

Answer:

Step-by-step explanation:

The white area is the area of the circle minus the area of the triangle.

Aw=pr^2-hb/2

Aw=p4^2-6.5(6)/2

Aw=16p-19.5

The probability of selecting the white area is the white area divided by the area of the circle

P(W)=(16p-19.5)/(16p), p=3.14

P(W)=0.61
