Determine whether the random variable is discrete or continuous. In each case, state the possible values of the random variable

yan [13]

Answer:

a) C. The random variable is discrete. The possible values are xequals0, 1, 2,....

b) B. The random variable is continuous. The possible values are x greater than or equals 0.

Step-by-step explanation:

Discrete variables are countable in a finite amount of time. Continuous variables can be infinitely many. They rather assume values in a range.

(a) Is the number of hits to a Web site in a day discrete or continuous?

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

(b) Is the weight of a Upper T dash bone steak discrete or continuous?

B. The random variable is continuous. The possible values are x greater than or equals 0.

In a sale normal prices are reduced by 10% natalie bought a pair of shoes in the sale for £54

Nookie1986 [14]

Answer:

Step-by-step explanation:

Steps to solve "54 is 90 percent of what number?"

We have, 90% × x = 54

or,

90/100 × x = 54

Multiplying both sides by 100 and dividing both sides by 90,

we have x = 54 × 100/90

x = 60

If you are using a calculator, simply enter 54×100÷90, which will give you the answer.

carol is excited to get a new kitten from the animal shelter. the kitten had an $299 adoption fee. carol had $50 off coupon for

Molodets [167]

Answer:

1 month

Step-by-step explanation:

249 is the amount she spends for buying the kitten, (299-50=249) which she only has to pay once.

20 is the amount she has to spend every month, the rate of change.

The problem can be modeled with the general equation:

y = 20x + 249

In this equation, x the the time in months and y is the amount of money spent.

Substitute 250 for y.

y = 20x + 249

250 = 20x + 249 <= isolate x to get the number of months

1 = 20x

x = 1/20

Carol will only spent money every month, not for 1/20 of a month.

It will only take Carol 1 month to spent $250.

Check answer:

Substitute x for 1

y = 20x + 249

y = 20(1) + 249

y = 269

269 is more than 250 already.

In a survey, 60% of interviewees say they like beach sports, while 55% like mountain sports. If 20% like both, what fraction of

My name is Ann [436]

Answer:

0.05

Step-by-step explanation:

To solve this problem, we first need to calculate the percentage of people that like beach or mountain sports.

This percentage can be calculated with the formula:

P(M or B) = P(M) + P(B) - P(M and B)

where:

P(M or M) is the percentage of people that like beach or mountain sports,

P(B) is the percentage of people that like beach sports,

P(M) is the percentage of people that like mountain sports,

P(B) is the percentage of people that like beach and mountain sports.

Then:

P(M or B) = 0.55 + 0.60 - 0.20 = 0.95

95% of the people like mountain or beach sport. Now, to find the percentage of people that like neither, we just need to make 1 minus the percentage of people that like beach or mountain sports:

P(Neither) = 1 - P(M or B) = 1 - 0.95 = 0.05

0.05 or 5% of the people interviewed like neither of these sports.
