Permutations acellus How many ways can 4 books be arranged on a shelf if there are 8 books to chose from? Note: nPr = n! —— (n-r)!

Answers

Answer:

1680 ways

Step-by-step explanation:

From the question,

nPr = n!/(n-r)!.................. Equation 1

Where, n = Total number of books to chose from, r = number of books to be arranged in the shelf.

Given: n = 8 books, r = 4 books.

Substitute into equation 1

8P4 = 8!/(8-4)!

8P4 = 8!/4!

8P4 = (8×7×6×5×4!)/4!

8P4 = 1680 ways.

Hence the number of ways 4 books can be arranged in a shelf if there are 8 books to chose from is 1680 ways

An insect population doubles every week. The function f(x)= 10(2)^x models the insect population after x weeks what will the population be after 4 weeks?
A.80
B.20,000
C.160

Answers

Given:

The insect population function is:

[tex]f(x)=10(2)^x[/tex]

Where x is the number of weeks.

To find:

The population after 4 weeks.

Solution:

The population of insect after x weeks is given by:

[tex]f(x)=10(2)^x[/tex]

We need to find the population after 4 weeks.

After substituting [tex]x=4[/tex], we get

[tex]f(4)=10(2)^4[/tex]

[tex]f(4)=10(16)[/tex]

[tex]f(4)=160[/tex]

The population after 4 weeks is 160. Therefore, the correct option is C.

A traffic light is green for 2 minutes, red for 40 seconds, and yellow for 10 seconds. When a car approaches the light, what is
the probability that it is not red?

Answers

here total second=170 second

probability that is not red=

[tex] \frac{12}{284} [/tex]

Step-by-step explanation:

i think that is the portability that is not red

The probability that the light is not red is 13/17

How to determine the probability?

The given parameters are:

Green = 2 minutes

Red = 40 seconds

Yellow = 10 seconds

Express green as seconds

Green = 120 seconds

The probability that the light is red is:

P(Red) =Red/Total

This gives

P(Red) = 40/(120 + 40 + 10)

Divide

P(Red) = 4/17

The probability that it is not red is:

P(Not Red) = 1 - P(Red)

This gives

P(Not Red) = 1 - 4/17

Subtract

P(Not Red) = 13/17

Hence, the probability that the light is not red is 13/17

2pi radians = 2*pi*9 = 18 pi

That's the circumference. Now you want to take pi/6 part of the circumference.

pi / 6 part of the circumference / 2pi is what you are looking for.

(pi / 6 // 2 pi) * 18 pi = 1/12 * 18 pi = 3/2 pi

Describe all 6 parts, for example, side "a" is one of the legs of the right triangle and is opposite Angle A, which is an acute angle, and side a appears to be the shortest side.

Answers

Answer:

The description of the 6 parts of the right triangle ABC are as follows;

The legs of the right triangle are side "a" and side "b"

The hypotenuse side of the right triangle is side "c"

The acute angles are ∠A and ∠B

The 90° angle is ∠C

The description of the 6 parts are therefore given as follows;

1) A; ∠A is the acute angle opposite side "a" and ∠A is formed between the hypotenuse side "c" and the leg "b"

2) B; ∠B is the acute angle opposite side "b" and ∠B is formed between the hypotenuse side "c" and the leg "a"

3) C; ∠C is the 90° angle (right angle) opposite the hypotenuse side "c" and ∠C is formed between the the two legs "a" and "b"

4) a; Side "a" is one of the two legs of the right triangle ΔABC and it is the leg opposite to ∠A

5) b; Side "b" is one of the two legs of the right triangle ΔABC and it is the leg opposite to ∠B

6) c; Side "c" is the hypotenuse side of the right triangle ΔABC and it (the hypotenuse side) is (all the time) the longest side of the right triangle and it is the leg opposite to ∠A
