Answer:

$m = 12.33$

Step-by-step explanation:

Given

Ferret:

$Weight = 2.1lb$

$Cost = \$3.40$

Labrador Retriever

$Weight = 70lb$

$Cost = \$7.50$

Required

Determine the slope

Represent the given as x or y

Taking the weight as explanatory variable;

We have:

x = 2.1; y = 3.4

x = 7.5; y = 70

Slope is calculated as:

$m = \frac{y_2 - y_1}{x_2 - x_1}$

$m = \frac{70 - 3.4}{7.5 -2.1}$

$m = \frac{66.6}{5.4}$

$m = 12.33$

<em>Hence, the slope is 12.33</em>

First five term for An=n^2-2n

densk [106]

First 5 terms are: -1,0,3,8,15

Step-by-step explanation:

we will put n=1,2,3,4,5 to find first 5 terms of the sequence

Explicit formula for sequence is:

$a_n = n^2-2n$

Putting n=1

$a_1 = (1)^2-2(1)\\= 1-2\\= -1$

Putting n=2

$a_2 = (2)^2-2(2)\\= 4 - 4 \\=0$

Putting n=3

$a_3 = (3)^2-2(3)\\= 9-6\\= 3$

Putting n=4

$a_4 = (4)^2 - 2(4)\\= 16-8 \\= 8$

Putting n=5

$a_5 = (5)^2-2(5)\\= 25 - 10\\= 15$

Hence,

First 5 terms are: -1,0,3,8,15

If you draw a card with a value of 4 or less from a standard deck of cards, I will pay you 165$ if not your pay me $45. (Aces ar

jekas [21]

Answer: The required expected value is $3.46.

Step-by-step explanation:

Since we have given that

Number of value of 4 or less are

2,3,4

So, there are 12 in numbers.

So, probability would be

$\dfrac{12}{52}$

Since Aces are considered as the highest card in the deck.

So, remaining probability would be

$\dfrac{40}{12}$

Amount paid or value of 4 or less = $165

Amount not paid for other case = $45

So, the expected value would be

$\dfrac{12}{52}\times 165-\dfrac{40}{52}\times 45\\\\=\dfrac{1980}{52}-\dfrac{1800}{52}\\\\=\dfrac{180}{52}\\\\=3.46$

Hence, the required expected value is $3.46.
