What is the probability of tossing a penny and landing on heads 3 times in a row

Mathematics
1 answer:
Rasek [7]3 years ago
4 0

Answer:

Suppose you have a fair coin: this means it has a 50% chance of landing heads up and a 50% chance of landing tails up. Suppose you flip it three times and these flips are independent. What is the probability that it lands heads up, then tails up, then heads up? So the answer is 1/8, or 12.5%.

A line intersects the points (-14,-10) and (7,5). find the slope of the line and simplify
Tpy6a [65]
The slope of any line can be calculated using the following rule:
slope = (y2-y1) / (x2-x1)

The given points are (-14,-10) and (7,5), therefore:
y2 = 5
y1 = -10
x2 = 7
x1 = -14

Substitute with these values to get the value of the slope as follows:
slope = (5--10) / (7--14) = 5/7

Sara bought a 16-ounce jar of strawberry jam for $3.20 What is the unit price?
wolverine [178]

Answer:

$0.20

Step-by-step explanation:

so you have 16 ounces of jam. i personally like jelly, but that's besides the point lol

so for those 16 ounces, you paid $3.20 for them.

unit price is just a term for the price of 1 item or measurement. you can use this to find out what product you are purchasing has the better deal, because you always want more product, for less money.

you should take the amount of money you are spending, and divide it by how many total ounces it has.

$3.20 / 16 = 0.20

this means that 1 ounce of jam costs $0.20

you can check your work by multiplying the price of one ounce, by how many ounces the jar is.

.2 * 16 = 3.20

i hope this was helpful to you and i explained well enough!

stay safe!!

:)
