Step-by-step explanation:

probability of an event = # times event has happened / total number of events

probability of someone liking potato chips or pretzels = # of people who like potato chips or pretzels / # total number of people

# of people who like potato chips or pretzels = # people who like potato chips + # people who like pretzels (this works because the two groups don't overlap)

Answer:

25.12 km

Step-by-step explanation:

The circle shape shown around the sphere is the circumference. The red line halfway through is the radius. To find the circumference of the circle using the radius, you must use this method: C = (2)(3.14)(r). 2 x 3.14 = 6.28. Next, multiply 6.28 x 4 because 4 is the radius. That equals 25.12. Therefore the circumference of the circle = 25.12 km.

1. Thad bought 8 notebooks that cost $3.79 each. If he gave the cashier a $50 bill, how much change did he get back from the purchase?
2.Lucy purchases a car for $16,314.40. If she makes a payment each month for the next 40 months, how much will she pay each month. (enter your answer as $dollars.cents)

Answers

Answer:

Step-by-step explanation:

1. Cost of each notebook = 3.79

Cost of 8 notebooks = 3.79 x 8 = 30.32

Amount gave to cashier = 50

Change = 50 - 30.32 = 19.68

407.86
Og. Cost - $16,314.40
Months - 40
I divided $16,314.40 by 40 and got $407.86

Lucy will pay $407.86 dollars each month for 40 months.

Find the range number of minutes.

Answers

Answer:

Range: 55

Step-by-step explanation:

Range = subtraction of the smallest number in the data set to the greatest number in the data set.

Greatest number: 1 hr (60 minutes)

Smallest number: 5 minutes

Range = 60 - 5

= 55

Hope this helps!

The answer is 55 darling

The Range is the difference between the lowest and highest values. Example: In {4, 6, 9, 3, 7} the lowest value is 3, and the highest is 9. So the range is 9 − 3 = 6. It is that simple!

The answer is 7x + 3

First, you have 3x-1 + 2x+1
Combine like terms and the 1’s cancel each other out. You are left with 5x.

Then, you add x+2 + x+1
Combine like terms and you have 2x+3

Add 5x + 2x+3 and you have 7x +3

So first we have to subtract the area of the other shapes. So…

352-

96
48
96
48

We will end up with 64

So divide that by 2 because there is 2 rectangles.

So then you’re left with an area of 32 for each rectangle!

Then you will do 42/4 (because one of the sides is 4) so you end up with 10.5

So then, that’s your missing side:

10.5 ft

The area of each missing face is 32ft squared and the length of each missing edge is 8ft squared

2. 6(-2 +x)
3. 6(-2 +x)

The pharmacist has a 2.8 L bottle of cough syrup. If she fills a bottle that is 1,200 ml, how many ml of cough syrup does the pharmacist have left?

160 ml
400 ml
1,600 ml
4,000 ml

Answers

Answer: 1,600 ml

Step-by-step explanation:

You can arrive at this answer by subtracting the amount of cough syrup used (1,200 ml) from the initial amount in the bottle (2.8 L, which is 2,800 ml).

2,800 ml - 1,200 ml = 1,600 ml

I hope this helps :)

Answer: 1,600 mL

Step-by-step explanation:

1. convert the 1,200 mL to L, which is 1.2 L.

2. Subtract that value from 2.8 L, equaling 1.6 L

3. Convert the 1.6 L back into mL by multiplying by 1000, which is equivalent to 1600 mL.
