Answer:

≈5.099

Step-by-step explanation:

1) the rule is:

$d=\sqrt{(x_1-x_2)^2+(y_1-y_2)^2};$

2) according to the rule above, the required distance is:

$d=\sqrt{(-2-3)^2+(-2+3)^2}=\sqrt{26}$

d≈5.099

Need help with my question

Alika [10]

Answer:

See below ~

Step-by-step explanation:

<h3>What is the rat population in 1993?</h3>

⇒ Number of years since = 0 ⇒ <u>t = 0</u>

⇒ Apply in the formula

⇒ n(0) = 73e^(0.02 × 0)

⇒ n(0) = 73e⁰

⇒ n(0) = 73,000,000 rats

=============================================================

<h3>What does the model predict the rat population was in the year 2009?</h3>

⇒ Number of years since 1993 : 2009 - 1993 = 16 ⇒ <u>t = 16</u>

⇒ Applying in the formula

⇒ n(16) = 73e^(0.02 × 16)

⇒ n(16) = 73e^(0.32)

⇒ n(16) = 73 × 1.37712776 × 10⁶

⇒ n(16) = 100.530326 x 10⁶

⇒ n(16) = 100,530,326 rats

In a particular game, a spinnerwith four equally-sized sectors labeled 1, 3, 4, and 6 is spun twice. One turn is considered 2 sp

galina1969 [7]

Each spin consists in a choice of a number among 1, 3, 4 and 6. This means that there are two odd numbers and two even numbers.

You get an even number if you sum two numbers with the same parity, you get an odd number if you sum two numbers with opposite parity.

Whatever number you get from the first spin, you have a 50% chance of spinning a number with the same parity with the second spin, and a 50% chance of spinning a number with opposite parity with the second spin.

So, with each turn, you have a 50% chance of getting an even sum, and a 50% chance of getting an odd sum.

This means that, by definition, the expected number of spaces moved is

$\dfrac{1}{2}\cdot 6 + \dfrac{1}{2}\cdot (-2) = 3-1 = 2$

So, on average, you move 2 steps foward.
