Answer:

B. The normal distribution has a mean of 0 and a standard deviation of 1.

C. The normal distribution cannot be used to approximate discrete probability distributions.

Step-by-step explanation:

We have to find the properties of normal distribution:

A) The given statement is false.

B) The given statement is true.

The normal distribution has a mean of 0 and a standard deviation of 1.

C) The given statement is true.

The normal distribution cannot be used to approximate discrete probability distributions because it is a continuous distribution and probability at any discrete value is zero.

D)The given statement is false.

The normal distribution has an area equal to 1.

determine the equation of the parabola (simplified) with roots -3+sqrt6 and -3-sqrt6, and passing through the point (-1,4)

klio [65]

Given:

Roots:

$\begin{gathered} -3+\sqrt[]{6} \\ -3-\sqrt[]{6} \end{gathered}$

Point: (-1,4)

To determine the equation of the parabola with the given roots and point, we find the missing values first.

Since the roots are given, we can say that the equation is:

$y=a(x+3-\sqrt[]{6})(x+3+\sqrt[]{6})$

Next, we expand the terms.

$y=a(x^2+6x+3)$

Then, we plug in x= -1, and y=4 into the equation to get the value of a.

$\begin{gathered} y=a(x^2+6x+3) \\ 4=a((-1)^2+6(-1)+3) \\ \text{Simplify and rearrange} \\ 4=a(-2) \\ a=\frac{4}{-2} \\ a=-2 \end{gathered}$

So,

Yesterday 170 guests at a hotel called for room service, and 255 guests did not call for ro service. What percentage of the gues

Levart [38]

Answer: 40%

Step-by-step explanation: you would need to find the total amount of guests which would be 425 since you’d add 170 and 255, then take the amount of guests that called for room service which is 170 and divide that by the total amount of guests 425 and you would get .4 then to get the percent you would multiply .4 by 100 which would equal 40%

The rectangle and the trapezoid have the same area. What is the length l of the rectangle?

Andre45 [30]

Answer:

length = 18 ft

Step-by-step explanation:

A(rect) = 9l

A(trap) = 1/2(9)(24+12) → 4.5(36) → 162

9l = 162

l = 162/9

l = 18
