Answer: -3n-2. 

Because for the first term, for example, plug in 1, you'll get -3(1)-2=-3-2=-5, which is the first one. Try it with all terms.

Need help with easy/quick probability problems. Do 1-6 and explain how to do one of them
alexandr1967 [171]

Answer:

P(algebra, then statistics) = 7/80

Step-by-step explanation:

The total number of books is 7 + 8 + 5 = 20.

1. P(algebra, then statistics)

The probability that the first book is an algebra book is 7/20.

Carlos then replaces the book, so the total is still 20.

The probability that the second book is a statistics book is 5/20.

Therefore, the total probability is:

P(algebra, then statistics) = 7/20 × 5/20

P(algebra, then statistics) = 7/80

What is the solution of the system? use substitution. 5x - y =3 6x - y=8
Bess [88]
5x - y = 3 ------------ (1)
6x - y = 8 ------------ (2)

From (1):
5x - y = 3
y = 5x - 3 ------------ Sub into (2)

6x - (5x - 3) = 8
6x - 5x + 3 = 8
x + 3 = 8
x = 5 ------------------- Sub into (1)

5x - y = 3
5(5) - y = 3
25 - y = 3
y = 25 - 3
y = 22

---------------------------------
Ans: x = 5, y = 22

The sample data below shows the number of hours spent by five students over the weekend to prepare for Monday's Business Statist
Levart [38]

Answer:

8.5 hrs

Step-by-step explanation:

-A 75th percentile mathematically means that  75% of the time data points are below that value and 25% of the time are above that value.

-We plot the given our data {3 12 2 3 5} to determine the 75th percentile

#We can use alcula.com to plot our boxplot.

-From the plot, we find our 75th percentile to be 8.5 hrs

Hence, 75% of the time the number of hours spent to prepare was less than 8.5hrs.
