Answer:

Step-by-step explanation:

P(x) = $\frac{2}{3x-1}$

Q(x) = $\frac{6}{-3x+2}$

P(x) × Q(x) = $\frac{2}{3x-1}\times \frac{6}{-3x+2}$

= $\frac{2\times 6}{(3x-1)(-3x+2)}$

= $\frac{12}{(3x-1)(-3x+2)}$

P(x) ÷ Q(x) = $\frac{2}{(3x-1)}$ ÷ $\frac{6}{(-3x+2)}$

= $\frac{2}{(3x-1)}\times \frac{(-3x+2)}{6}$

= $\frac{(-3x+2)}{3(3x-1)}$

In a recent survey in a Statistics class, it was determined that only 74% of the students attend class on Fridays. From past dat

Anna007 [38]

Answer:

a) 83%

b) 0.892

Step-by-step explanation:

percentage that attends class on friday = 74%

percentage that pass because they attend class on friday = 88%

percentage that pass but did not go to school on friday = 20%

a) percentage of students expected to pass the course

= (74% x 88%) +(88% x 20%)

= 0.6512 + 0.176

= 0.8272

= 83%

b) If a person passes the course, what is the probability that he/she attended classes on Fridays

= 74% divided by 83%

= 0.892

Write your answer as a fraction or as a whole or mixed number. 27pts

statuscvo [17]

What we know:

Bird feeder capacity: --> 2 4/5 cups
Samantha's scoop capacity: --> 7/10 cups

Lets first convert the mixed partial fraction --> improper fraction

--> for easier calculation

After Conversion:

Bird feeder capacity: --> 14/5 cups
Samantha's scoop capacity: --> 7/10 cups

To find how many scoops of birdseed will Samantha put into the feeder we must:

--> divide the total capacity by the scoop's capacity

--> find the number of scoops:

Solve:

$Total-number- of -scoops = \frac{\frac{14}{5} }{\frac{7}{10} } =\frac{14}{5} *\frac{10}{7} =\frac{14*10}{5*7} =\frac{14}{7} *\frac{10}{5} =2*2=4$

Thus the total number of scoops that Samantha will put into the bird feeder is 4

Answer: 4

Hope that helps!

Explain how to determine if you have a direct variation or proportional relationship

neonofarm [45]

Answer:

straight line that passes through the origin

Step-by-step explanation:

Two variables are said to have a direct variation or proportional relationship if it can be represented by y = kx, where k is a constant.

Comparing this with the equation of a straight line y = mx + b, where m is the slope of the line and b is the y intercept (value of y when x = 0), We can tell if the say that the graph of a direct variation or proportional relationship is a straight line with no y intercept (b = 0, that is it passes through the origin).
