Suppose a six-sided die is tossed 1200 times and a 6 comes up 419 times. (a) Find the empirical probability for a 6 to occur. (E

krok68 [10]

Answer:

Here both probabilities are not equal.

Therefore the die is not fair and biased.

Step-by-step explanation:

Now n= 1200 times and x = 419 times.

a) Empirical Probability:

$=\frac{x}{n} \\\\= \frac{419}{1200}\\ \\=0.349$

Probability = 0.349

b) Theoretical Probability:

$=\frac{1}{6}$

Here both probabilities are not equal.

Therefore the die is not fair and biased.

Cd has an endpoint at (2, -1) and a midpoint at (8, 3). which measure is closest to the length of cd

stepladder [879]

Answer:

4 $\sqrt{13}$

Step-by-step explanation:

The length of CD will be twice the distance from the midpoint to the endpoint

To calculate the length use the distance formula

d = √ (x₂ - x₁ )² + (y₂ - y₁ )²

with (x₁, y₁ ) = (2, - 1) and (x₂, y₂ ) = (8, 3)

d = 2 × $\sqrt{(8-2)^2+(3+1)^2}$

= 2 × $\sqrt{6^2+4^2}$

= 2 × $\sqrt{52}$

= 2 × $\sqrt{4(13)}$

= 2 × 2 $\sqrt{13}$ = 4 $\sqrt{13}$ ← exact length

<span>fixed annual membership fee of $20
</span><span>$2 per video game rented.
</span><span>Let f(n) represent the total annual cost of renting n video games
so
f(n) = 20 + 2n

if </span><span>increased by $15 the next year
then
f(n) = </span>20 + 2n + 15
f(n) = 2n + 35

answer

A || b what’s the value of X?

Anna007 [38]

<h3><u>Answer:</u></h3>

The value of x is 17.

<h3><u>Step-by-step explanation:</u></h3>

<u>We know that the lines are parallel because it is given that:</u>

a ∥ b

<u>Now, let's form an equation.</u>

=> 2x + 5 + 8x + 5 = 180

<u>Let's solve!</u>

=> 10x + 10 = 180
=> 10x = 170
=> x = 17

Hence, the value of x is 17.
