Spinner goes 1-4. Jose spins the spinner 8 times. In those 8 spins, the arrow never lands on 3. Based on this information, should Jose be concerned that the spinner is unfair? Explain.

Answers

Answer 1

Answer: If the spinner was fair, the probability of landing on 3 in a single spin is 1/4. The probability of never landing on 3 in 8 spins is (3/4)^8 = 0.1. The probability of landing on 3 at least once in 8 spins is 1 - 0.1 = 0.9.
Therefore Jose should be concerned that the spinner is unfair.

Answer 2

Answer: Well this is a more complicated question than it may seem. The laws of probability are based on observations whose number is very large or actually as the number of observations approaches infinity. So on the one hand, you should be concerned that you get 0/8 to land on 3. However, 42/500 land on 3 so your ratio has improved. It's not near 125 but it's also not 0. If it remained at 0, you would begin to be concerned and rightly so. Perhaps if you did 5000, you would be less concerned as the ratio improved and got closer to 1/4 of the observations. So at this point I don't think you have enough information to determine that the spinner is unfair.

Whats the integral of 1/X

Answers

$F(x) = \int\limits (1)/(x) dx =\int\limits x^-^1 dx \n f(x) = \int\limits x^-^1dx = (1)/(0) X^0$

$= f(x) = \int\limits X^-^1dx = In|x|$

$\left(\ln(|x|)\right)'=\frac{1}x$ hence $\int\frac{1}xdx=\ln |x|$

Which set of polar coordinates describes the same location as the rectangular coordinates (0, -2)

Answers

Polar coordinates identifie the points of the plane by a distance from the reference point and an angle from a reference direction.

In this case the distance of (0,-2) from the origin is 2 and the anglefrom the x-axis is 180°. So the polar coordinates are (2, 180°)

Enter the value of p so the expression 5/6 - 1/3n is equivalent to p(5-2n).

Answers

Let's solve for p when the two expressions are equal.

$p(5-2n)=\frac{5}6 - \frac{1}3n \n\n p=\frac{\frac{5}6-\frac{1}3n}{5-2n}*\frac{6}6= (5-2n)/(6(5-2n)) = \boxed{\frac{1}6}$

What times what equals 96

Answers

The requried 96 can be expressed as the product of two numbers in five different ways,

96 = 2 x 48

96 = 3 x 32

96 = 4 x 24

96 = 6 x 16

96 = 8 x 12

What is the factors?

A number or algebraic expression that evenly divides another number or expression—i.e., leaves no remainder—is referred to as a factor.

Here,
To find two numbers that multiply to 96, we can factorize 96 into its prime factors:

96 = 2 x 2 x 2 x 2 x 2 x 3

Now we can group these factors into pairs, where each pair multiplies to 96,

2 x 48 = 96

3 x 32 = 96

4 x 24 = 96

6 x 16 = 96

8 x 12 = 96
