FIRST GETS BRAINIEST Michael finds that 35 customers at his grandfather's grocery store use a coupon. To simulate the behavior o

f the next 5 customers, he writes the numbers 1, 2, 3, 4, and 5 on cards and mixes them up. He writes down that 1, 2, and 3 represent someone using a coupon and 4 and 5 represent someone not using a coupon. Michael then randomly selects a card, puts it back, and records the number. He repeats this 5 times to represent 5 customers or 1 trial. He repeats this experiment for a total of 15 trials. The results are shown in the table. 43454 24511 55555 43453 55315 25215 32235 43311 11154 13342 42514 13223 44215 45313 13324 Using this simulation, what is the probability that, out of the next 5 customers, 4 or more will use a coupon? Enter your answer, as a fraction in simplified form, in the box. FIRST GETS BRAINIEST

1/3 is the answer! (for future visitors)

There were 5 of the 15 in the simulation that used a coupon.  To find the probability you just divide 5 by 15

P(=>4) = 5/15 = 1/3 - probability of 4 or more

Which statement describes how to determine if a relation given in a table is a function?
const2013 [10]

Answer: B

Step-by-step explanation: A function is a relation in which each input value is paired to exactly one output value.

Technically, if you had the same input value twice and the same output value corresponded to each of those, it would still be a function because you are just repeating what you have twice.

However, most teachers want to think of it as each input value must have exactly one corresponding value to be a function.

Graph the linear equation x-3y=-6
TEA [102]

Answer:

Step-by-step explanation:

One of the easier approaches to graphing a linear equation such as this one is to solve it for y, which gives us both the slope of the line and the y-intercept.

x-3y=-6 → -3y = -x - 6,  or 3y = x + 6.

Dividing both sides by 3, we get   y = (1/3)x + 2.

So the slope of this line is 1/3 and the y-intercept is 2.

Plot a dot at (0, 2).  This is the y-intercept.  Now move your pencil point from that dot 3 spaces to the right and then 1 space up.  Draw a line thru these two dots.  End.

Alternatively, you could use the intercept method.  We have already found that the y-intercept is (0, 2).  To find the x-intercept, let y = 0.  Then x = -6, and the x-intercept is (-6, 0).

Plot both (0, 2) and (-6, 0) and draw a line thru these points.  Same graph.

Somebody please help me with my homework it do tomorrow!!!
xxTIMURxx [149]

The solution to given system of equations is (x, y) = (2, -1)

<em><u>Solution:</u></em>

Given system of equations are:

-1x + 2y = -4  -------- eqn 1

4x + 3y = 5 ------- eqn 2

We can solve the above system of equations by elimination method

<em><u>Multiply eqn 1 by 4</u></em>

4(-1x + 2y = -4)

-4x + 8y = -16  ------ eqn 3

<em><u>Add eqn 2 and eqn 3</u></em>

4x + 3y = 5

-4x + 8y = -16

( + ) --------------------

0x + 11y = -16 + 5

11y = -11

y = -1

<em><u>Substitute y = -1 in eqn 1</u></em>

-1x + 2(-1) = -4

-x -2 = -4

-x = -4 + 2

-x = -2

x = 2

<em><u>Check the answer:</u></em>

Substitute x = 2 and y = -1 in eqn 2

4x + 3y = 5

4(2) + 3(-1) = 5

8 - 3 = 5

5 = 5

Thus the obtained answer is correct

Thus the solution to given system of equations is (x, y) = (2, -1)
