Write down in terms of n an expression for the nth term of the following sequence. A) 25,20,15,10,5

Answers

Answer 1

Answer:

(30-5n)

Step-by-step explanation:

The given sequence is :

25,20,15,10,5

Here,

First term, a = 25

Common difference = 20-25 = -5

We need to find the nth term of the given sequence. The formula for the nth term is given by :

[tex]a_n=a+(n-1)d\\\\a_n=25+(n-1)(-5)\\\\=25-5n+5\\\\=30-5n[/tex]

So, the nth term of the above sequence is (30-5n).

Timothy has 2 turtles named Buster and Bubbles. Buster is 75 millimeters long and Bubbles is 6 centimeters long. Buster is longer. Is this true or false?

Answers

Answer:

TRUE

Step-by-step explanation:

Buster measures 75 millimeters.

This converts to 7.5 centimeters.

Buster's length of 7.5 centimeters is greater than Bubble's length of 6 centimeters.

When the Buster is 75 millimeters long and Bubbles is 6 centimeters long so here the Buster should be longer. So, it is true.

Calculation of who is longer:

Since Timothy has 2 turtles named Buster and Bubbles. Buster is 75 millimeters long and Bubbles is 6 centimeters long

Now if convert 75 millimeters to centimeters so it is 7.5 centimeters.

And the Bubbles is 6 centimeters long

So based on this, we can say that buster should be longer.

We will remove two marbles from a jar that contains 3 green marbles, 2 blue marbles, 1 white marble, and 1 black marble. We might consider the conditional probability that the second marble we remove is green given that the first marble removed was green. Use the multiplication rule to calculate P( second green | first green). Convert your answer to a decimal and round to three decimal places.

Answers

Answer:

P( second green | first green) = 1/3

Step-by-step explanation:

There are 7 marbles in the jar in total

After the first pick, given the marble removes is green marbles, how many green marbles are there left in the jar? How many marbles are there left in the jar?

Green marbles left: 2

Marbles left: 6

Using the multiplication law of probability,

P(A∩B) = P(A) x P(B|A)

P(second green | first green) = P(second green and first green) / P(first green)

P(second green and first green) = 3/7 x 2/6 = 1/7

P(first green) = 3/7

∴(1/7) / (3/7) = 1/3

Thus, we come up to the conclusion P( second green | first green) = 1/3

What is the equation of the line that passes through the point (2,7) and has a slope
of 6?

Answers

Answer (assuming it can be in point-slope form):

[tex]y-7 = 6(x-2)[/tex]    

Step-by-step explanation:

Use the point-slope formula [tex]y-y_1 = m (x-x_1)[/tex] to write the equation of the line in point-slope form. All you need to do is substitute [tex]m[/tex], [tex]x_1[/tex], and [tex]y_1[/tex] for real values.

Since [tex]m[/tex] represents the slope, substitute 6 in its place. Since [tex]x_1[/tex] and [tex]y_1[/tex] represent the x and y values of one point the line intersects, take the x and y values of (2,7) and substitute them into the formula as well. So, substitute 2 for [tex]x_1[/tex] and 7 for [tex]y_1[/tex]. This gives the following equation and answer:

[tex]y-7 = 6(x-2)[/tex]
