State whether the graph of the linear relationship is a solid line or a set of unconnected points. Complete the explanation of your reasoning.

The relationship between the number of $3 lunches you buy with a $150 school lunch card and the money remaining on the card

The relationship is a ( set of unconnected points, solid line )
because you (can, cannot) buy a ( positive number of lunches, fractional part of a lunch)

Answers

Answer 1

Answer:

The relationship is a solid line because you can buy a positive number of lunches.

Step-by-step explanation:

$3 lunches $150 school lunch card

Let number of lunches = x

Let number of amount remaining on card = y

y = 150 - 3x

When you buy 1 lunch

y = 150 - 3(1)

150 - 3

y = 147

When you buy 2 lunches

y = 150 - 3(2)

150 - 6

y = 144

The decrease in the amount is constant and you can see on the graph that it is linear.

Give an example of a compound event.
How do you calculate the probability of a compound event?

Answers

Compound probability is equal to the probability of the first event multiplied by the probability of the second event.

Just multiply the probability of the first event by the second. For example, if the probability of event A is 2/9 and the probability of event B is 3/9 then the probability of both events happening at the same time is (2/9)*(3/9) = 6/81 = 2/27.

Answer:

Compound probability is equal to the probability of the first event multiplied by the probability of the second event.

what equation do you get when you solve h-t=h+px for p?

Answers

We will want to get p by itself
h-t=h+px
We will first subtract h from the right and left
-t = px
We will then divide by x on both sides
-t/x = p

-t/x=p this is the equation that you get when you solve for p

2. Line A passes through the points (0,-5) and (12,1). Line b passes through the points (0,-4) and (10,1).

Write an equation for each line.

How many times will the lines intersect? How do you know?

can some help me pls and dont give me fake answer

Answers

so if line A passes through (0,-5) and (12,1) you can put it into the equation m=y2-y1/x2-x1. m=1+5/12-0 m=6/12 or m=1/2
if line B passes through (0,-4) and (10,1) you can use the same equation to find the slope. m=1+4/10-0 m=5/10 or m=1/2
(0,-5) and (0,-4) are y-intercepts so you can now put it into the equation y=mx+b
line A: y=1/2x-5
line B: y=1/2x-4
because the slope is the same and the y-intercept is different they will never intersect.
let me know if this helped i’m glad to.

Nikki has an Apple iTunes gift card with a credit of $20. She spends $20 downloading music and games. Write an ADDITION equation that represents this situation?

Answers

Answer:

Ill answer this and hope you meant subtraction if not, this is wrong.

20 - 20 = 0

Step-by-step explanation:

Well, you can't write an addition problem for subtraction which is the only thing happening in that situation, because Nikki is only losing money.

I think it may be negative twenty plus twenty equals 0? So -20+20=0? That is the only way I could think of to make it an addition problem. Sorry I don't know lol, hope this helps

Answer:

7/16 C.

Step-by-step explanation:

You need to find the common denominator which in this case is 16...it takes 8, two times to get to 16 which 1 times 2 is 2 so therefore it would 5+2 which is 7 and the common denominator stays the same so it would be 7/16. If you are still confused just private message me and I’d be happy to help if you though this was helpful please mark me as branlist thanks! HAVE A GOOD DAY!!!

Answer:

7/16

Step-by-step explanation:

you can divide 8 and 16 by 2 so do multiply 8x2 and that will give you 16, then you add you also add 1 to the one to make two and then it will become 2/16+5/16 then that will give you 7/16. I actually typed this all in.

There are 233 skiers in line to ride the chair lift. If each chair seats 5 people, how many skiers will be on the last chair?

Answers

Answer:

At first we will divide 233 with 5

233/5= 46.6

So,

there will be 46.6 chairlifts occupied

After that we will subtract 233 from 46

233-46=186/5=37

So,

there will be 37 skiers on the last chair lift

Step-by-step explanation:

Answer:

3 people will be seated on the last chair.

Step-by-step explanation:

46 seats can fit 5 people perfectly. But if you multiply 46*5, it will equal 230, and that isn't the total number of skiers. So, you only need 3 more skiers to make up the total, so that means that there will be 3 skiers in the last chair.
