Step-by-step explanation:
GIVEN: Emma started biking to the coffee shop traveling 
, after some time the bike got a flat so Emma walked the rest of the way, traveling 
If the total trip to the coffee shop took 
and it was 
away.
TO FIND: how long did Emma travel at each speed.
SOLUTION:
Let the distance traveled by Emma through bike is 
Total time taken when traveled by bike 
Distance traveled through feet 
Total time taken when traveled by feet 
Now,
Total time taken 
Distance traveled through feet 
Hence distance traveled using bike is 
and by feet is 
When Z=3 it is 45 and when Z=-3 it is also 45.
Answer:
A histogram often looks similar to a bar graph, but they are different because of the level of measurement of the data. Bar graphs measure the frequency of categorical data. A categorical variable is one that has two or more categories, such as gender or hair color
Step-by-step explanation:
The sample space of Shari's tree diagram is the total possible outcomes of rolling the game piece and spinning the pointer.
It doesn't matter if Shari starts with the spinner or the game piece
<h3>How to determine the tree diagram</h3>
The experiment involves:
- Rolling a 12-sided game piece
- Spinning the pointer of a 4-section spinner
If Shari starts with the game piece, the sample size (n) would be:
n = 12 * 4
n = 48
If Shari starts with the spinner, the sample size (n) would be:
n = 4 * 12
n = 48
Notice that the sample size remains unchanged irrespective of what he starts with
Hence, it doesn't matter if Shari starts with the spinner or the game piece

Multiply by 1
Add 1 1 11 11
to both sides of the equation
