To understand unit rates, always keep the number 1 in mind.

Let’s say we’re looking at a table with the input of 2 and output of 6. The first step is to find what the multiplier is.
If we divide 6 and 2, we get 3. Another way to think about it is “what multiplied by 2 gets 6?” So we now know our multiplier is 3.

However, it is not the unit rate. The unit rate is the base number (1) and the multiplier.

To get the the base number and the multiplier, we now have to look for a number that can be divided by both the input and output. In this case, the number 2.

2 divided by 2 is 1. 6 divided by 2 is 3. We now have the numbers 1 and 3. These are the base numbers.

When thinking of unit rate, we know that a unit is one part of ____, so one unit plus another unit goes on and on.

Hope this helps!

answer to three friends each create 4 bags of starter bread dough. after ten days, each of those four bags is then divided into
vlabodo [156]
The answer is 20 days, we can solve this in following way:
Each friend creates 4 bags of dough and after ten days four bags divided into four more bags means:
3 friends x 4 bags = 12 bags  and 12 bags  x 4 = 48 bags
so in next 10 days, the 48 bags will be further divided into 4, so 
48 x 4 = 192 bags
10 days  + next 0 days  = 20 days
so 20 days is the answer.

I'm giving brainliest to the most helpful answer. For 50 points:
Alenkinab [10]

Answer:

1) \displaystyle\frac{5}{18}\approx27.78\%

2) \displaystyle\frac{4}{7}\approx57.14\%

3) \displaystyle  \frac{13}{16}=81.25\%

Step-by-step explanation:

We are given a two-way frequency table. Using the table, we will determine the probability for each case.

Question 1)

P(A Student With A Part Time Job Without A Car)

Using the first column, the total number of students that have a part time job is 78+30=108.

Likewise, using the first column, we can see that out of those 108 students, 30 do not have a car.

Hence, the probability that a student with a part time job without a car is:

\displaystyle P=\frac{30}{108}=\frac{5}{18}\approx27.78\%

Question 2)

P(No Car | Does Not Have A Part Time Job)

Remember that the vertical line means conditional probability.

So, we want the probability of a student having no car given that they do not have a part time job.

Using the second column, we can see that the total number of students that do not have a part time job is 18+24=42.

Likewise, using the second column, 24 do not have a car.

Hence, the probability that a student with a part time job without a car is:

\displaystyle P=\frac{24}{42}=\frac{4}{7}\approx57.14\%

Question 3)

P(Part Time Job | Car)

So, we want to probability of a student having a part time job given that they have a car.

Using the first row, the total students that have a car is 78+18=96.

And of those 96 students, 78 have a part time job.

Hence, the probability that a student with a car has a part time job is given by:

\displaystyle P=\frac{78}{96}=\frac{13}{16}=81.25\%
