Answer:

a. 1.94

b. 1.94

c. 1.05

d. 1.15

e. 0.44

f. 0.44

Step-by-step explanation:

z-table is used to calculate the values

<u>a. The area to the left of z is .9738</u>

z= 1.94

<u>b. The area between 0 and z is .4738 ( is positive)</u>

z= 1.94

<u>c. The area to the left of z is .8531</u>

z=1.05

<u>d. The area to the right of z is .1251</u>

z=1.15

<u>e. The area to the left of z is .6700</u>

z=0.44

<u>f. The area to the right of z is .3300</u>

z=0.44

Determine whether the random variable is discrete or continuous. In each​ case, state the possible values of the random variable
Deffense [45]

Answer:

C. The random variable is discrete. The possible values are x= 0, 1, 2... 100

C. The random variable is continuous. The possible values are a > 0.

Step-by-step explanation:

Here is the complete question :

Determine whether the random, variable is discrete or continuous.

In each case, state the possible values of the random variable.

(a) The number of people in a restaurant that has a capacity of 100

(b) The square footage of a house.

(a) Is the number of people in a restaurant that has a capacity of 100 discrete or continuous?

A. The random variable is discrete. The possible values are 0≤x≤ 100.

B. The random variable is continuous. The possible values are 0≤x≤ 100.  

C. The random variable is discrete. The possible values are x= 0, 1, 2... 100

D. The random variable is continuous. The possible values are x= 0, 1, 2... 100

b) Is the square footage of a house discrete or continuous?

A. The random variable is discrete. the possible values are a > 0  

B. The random variable is discrete. The possible values are a = 1, 2, 3...

C. The random variable is continuous. The possible values are a > 0.

D. The random variable is continuous. The possible values are a = 1,2, 3,

A discrete variable is a variable that can be counted. It has a finite amount of values. The number of people in the restaurant is finite. It cannot exceed 100. At any point in time when you count the number of people in the restaurant and it would be between 0 - 100

A continuous variable has an infinite amount of values it can take on. The square footage of a house can be of any size. there is no limit to the size of a house. it can be as small or big as the architect's imagination allows.

The product of a linear monomial and a linear binomial is a ​
oksian1 [2.3K]

Answer:

The product of a linear monomial and a linear binomial is a second degree binomial

Step-by-step explanation:

Examples of linear monomials are:

2x

2a

y

Examples of linear binomials are:

2x+y

x-y

3a+b

x+1

When we take the product of a linear monomial and a linear bbinomial we obtain:

2a(3a+b)=6a²+2ab

y(x+1)=xy+y

y(x-y)=xy-y²

These are all second degree binomials.

PLEASE HELP QUICK Suppose a particle is moving along the x-axis. The position, measured in feet, of the particle can be modeled
Romashka-Z-Leto [24]

When 'x' is zero, 'y' is -9.

That simply means that when time began ... when the starter

fired his pistol and the clock started running ... the particle

was 9 units 'before' zero, in the region of negative location.


By the way ... the way the question is written is enough to confuse

anyone, and I hope that hasn't contributed to your trouble with it.


If the particle is moving along the x-axis, then 'x' is its location,

and the time in seconds is something else. Say 't' for example.

Also, if it's moving along the x-axis, then 'y' is always zero.


The position of the particle is modeled by an equation like


X = 3t² - 12t - 9 .


'X' is the position of the particle, and 't' is the time in seconds.
