It is assumed that the time customers spend in a record store is uniformly distributed between 3 and 12 minutes. Based on this i
monitta

Answer:

0% probability that a customer will be exactly 7.50 minutes in the record store.

Step-by-step explanation:

Uniform probability distribution:

An uniform distribution has two bounds, a and b.  

The probability of finding a value of at lower than x is:

P(X < x) = \frac{x - a}{b - a}

The probability of finding a value between c and d is:

P(c \leq X \leq d) = \frac{d - c}{b - a}

The probability of finding a value above x is:

P(X > x) = \frac{b - x}{b - a}

The uniform distribution is a continuous distribution, which means that the probability of an exact outcome is zero.

Uniformly distributed between 3 and 12 minutes.

This means that a = 3, b = 12

What is the probability that a customer will be exactly 7.50 minutes in the record store?

Continuous distribution, so:

0% probability that a customer will be exactly 7.50 minutes in the record store.

miv72 [106K]

Answer:

slope (m) = -\frac{3}{4}

Step-by-step explanation:

Slope of the line using two pairs of values from the table, (-2, 5) and (2, 2):

slope (m) = \frac{y_2 - y_1}{x_2 - x_1} = \frac{2 - 5}{2 - (-2)} = \frac{-3}{4}

slope (m) = -\frac{3}{4}

Use calculator to draw the graph F(x)=x^4-4x^3-x^2+12x-2
ohaa [14]

Answer:

Here's what I got  

Step-by-step explanation:

I used an online graphing calculator and got the graph below.

The function has zeroes at (-1.756,0), (0.738, 0), (1.564, 0), and (3.453, 0).

There are local minima at (-0,939, -15.061) and (2,795,-7,853) and a local maximum at (1.144, 1.143).

The end behaviour is

F(x) ⟶ ∞ as x ⟶ -∞

F(x) ⟶ ∞ as x ⟶ ∞

2ab( 4a2 + 3ab - 7b2)​
Kisachek [45]

Answer:

6ab + -3a2

Step-by-step explanation:

2ab(4a2 + 3ab - 7b2)     original problem

2ab(3ab + 4a2 - 7b2)     commutative property

2ab(3ab + -3a2)     subtract

4 - 7 = -3

6ab + - 3a2              mulitiply

2ab x 3ab = 6ab

and that is you final expression, you can't add the last 2 numbers cause they are not like terms.
