Hey everyone. I need the answer to this ASAP!: Michael knows that 2 cans of paint is the exact amount he needs to paint a 10-foo

t by 12-foot wall. Graph the relationship between the total square feet of the walls and the number of paint cans necessary to paint them. Show your work or explain how you got your graph in part A . There is a picture of the graph attached.​

Answer:

See attachment for graph

<em></em>

Step-by-step explanation:

Given

2 cans = 10ft\ by\ 12ft

Required

Graph the relationship between both parameters

First, calculate the area;

Area = 10ft * 12ft

Area = 120ft^2

This implies that: (2, 120) i.e. 2 cans for 120ft^2.

So we have:

(0,0) and (2,120)

(0,0) implies that: 0 cans for 0 square feet

Calculate the slope:

m = \frac{y_2 - y_1}{x_2 - x_1}

m = \frac{120 - 0}{2-0}

m = \frac{120 }{2}

m  = 60

The equation is:

y = m(x - x_1) + y_1

So, we have:

y = 60 * (x - 0) + 0

y = 60 * (x )

y = 60 x

Veseljchak [2.6K]

Answer:

In a certain Algebra 2 class of 30 students, 22 of them play basketball and 18 of them play baseball. There are 3 students who play neither sport. What is the probability that a student chosen randomly from the class plays both basketball and baseball?

I know how to calculate the probability of students play both basketball and baseball which is 1330 because 22+18+3=43 and 43−30 will give you the number of students plays both sports.

But how would you find the probability using the formula P(A∩B)=P(A)×p(B)?

Thank you for all of the help.

That formula only works if events A (play basketball) and B (play baseball) are independent, but they are not in this case, since out of the 18 players that play baseball, 13 play basketball, and hence P(A|B)=1318<2230=P(A) (in other words: one who plays basketball is less likely to play basketball as well in comparison to someone who does not play baseball, i.e. playing baseball and playing basketball are negatively (or inversely) correlated)

So: the two events are not independent, and so that formula doesn't work.

Fortunately, a formula that does work (always!) is:

P(A∪B)=P(A)+P(B)−P(A∩B)

Hence:

P(A∩B)=P(A)+P(B)−P(A∪B)=2230+1830−2730=1330

A line is graphed to show the relationship between the number of words typed and the time Mary spends on a typing test.
Ilya [14]
Thanks for including the graph! 

Okay, so -

From examining the graph, we can see that for every minute the number of words increases by 40. 

Now, since the x axis (the horizontal thingy kabob at the bottom) is time, and the y axis (the vertical thingy kabob) is the number of words - we can conclude that the answer is B! 

Just remember that the value of the y axis is dependent on the value of the x axis. Also, note that x almost always represents time!

What would be the equation for this line?
Nata [24]

Answer:

  y = -x -2

Step-by-step explanation:

  The line goes down 1 grid square for each grid square to the right. Hence its slope is -1. The graph shows the y-intercept to be -2, so the slope-intercept equation with m = -1 and b = -2 is ...

  y = mx + b

  y = -x -2
