Answer:

18 tests

Step-by-step explanation:

Create a proportion where x is the number of tests after 9 weeks:

$\frac{10}{5}$ = $\frac{x}{9}$

Cross multiply and solve for x:

5x = 90

x = 18

So, after 9 weeks, Vera will have taken 18 tests

Λ represents the average rate, and the expected number of events in a given time frame for the ____________ distribution.

enot [183]

Answer:

The correct answer is:

Poisson (A.)

Step-by-step explanation:

A Poisson distribution is used to model the number of events occurring within a given time interval, when the average number of times that the event occurs within the time interval is given.

Lambda ( λ ) is a rate parameter in Poisson's distribution, and it is used to represent "event/time", and it simply represents <em>the expected number of events in the interval.</em>

4688-3) -30X-5 CX-5)

pshichka [43]

Answer:

x = 13/3

Step-by-step explanation:

4(8x-3) - 30x = 5(x-5)

Distribute

32x - 12 - 30x = 5x -25

Combine like terms

2x -12 = 5x-25

Subtract 2x from each side

2x-12-2x = 5x-2x -25

-12 = 3x-25

Add 25 to each side

-12+25 = 3x-25+25

13 = 3x

Divide each side by 3

13/3 = x
