In order to simplify the product, multiply the factors by taking the term in the first factor and multiplying it to every term in the second factor. Then take the second term in the first factor and multiply it to every term in the second factor. Add all terms and the correct answer is $x^2 - x -12$

What are the relative frequencies, to the nearest hundredth, of the rows of the two-way table?

sveta [45]

Answer: A B

Group 1 0.25 0.75

Group 2 0.44 0.56

Step-by-step explanation:

Since we have given that

Number of people of A in group 1 = 15

Number of people of B in group 1 = 45

Total number of people in group 1 is given by

$15+45=60$

Relative frequency of people of A in Group 1 is given by

$\frac{15}{60}=0.25$

Relative frequency of people of B in Group 1 is given by

$\frac{45}{60}=0.75$

Similarly, Number of people of A in group 2 = 20

Number of people of B in group 2 = 25

Total number of people in group 2 is given by

$20+25=45$

Relative frequency of people of A in Group 2 is given by

$\frac{20}{45}=0.44$

Relative frequency of people of B in Group 2 is given by

$\frac{25}{45}=0.56$

Hence, A B

Group 1 0.25 0.75

Group 2 0.44 0.56

Answer:

192.972 mi/h

Step-by-step explanation:

To solve this, you have to add up all of the speeds and divide by how many values there are.

So if all of them are added together, it equals 771.888. Then, you divide this number by 4 to find the average. In this case, the average is 192.972mi/h.
