Hey

Question 1: For this one, we simply need to look at the "fat grams over 25" and the "Total" sections. We can see that 27 out of 50 have fat grams over 25. This written as a percentage is: 54%

Question 2: Using the same logic above we conclude the answer is 45.45%

Question 3: For this we need to look at the "total" section and the answer is 50

Question 4: We add all the "over 300" and write it as a percentage out of 50 which is 14%

Question 5: Same as #1 answer is 21%

Hope this helps

The probability distribution for the random variable x follows. x f(x) 20 0.20 25 0.15 30 0.30 35 0.35 (a) Is this probability d
Damm [24]

Answer:

(a) The probability distribution is valid.

(b) The probability that x = 30 is 0.30.

Step-by-step explanation:

The probability distribution of the random variable <em>X</em> is:

<em>    x</em>:  20   |  25  |  30   |   35

f (<em>x</em>): 0.20 | 0.15 | 0.30 | 0.35

(a)

The properties of a probability distribution are:

  1. 0 ≤ P (X) ≤ 1
  2. ∑ P (X) = 1

All the probability value are more than 0 and less than 1.

Compute the sum of all the probabilities as follows:

\sum P(X)=0.20+0.15+0.30+0.35=1

The sum of all probabilities is 1.

Thus, the probability distribution is valid.

(b)

Consider the probability distribution table.

The probability of <em>X</em> = 30 is,

P (X = 30) = 0.30.

Thus, the probability that x = 30 is 0.30.

If rain is falling at 0.5 inches per hour and 1.5 inches have already accumulated, how many hours must have passed if there are
zavuch27 [327]

Given :

Rain is falling at 0.5 inches per hour and 1.5 inches have already accumulated.

To Find :

How many hours must have passed if there are 5 inches of rain .

Solution :

Let , after x hours rain accumulated is 5 inches .

We know , general equation of line :

y = mx +c

Here , m = 0.5 and c = 1 .

So , equation of rain accumulated is :

y=0.5x+1

Now , putting value of x = 5 hours .

We get :

y=0.5\times 5+1\\\\y=2.5+1=3.5\ inches

Hence , this is the required solution .

Professor Nwamabi is conducting an experiment in which he is examining the effects of air conditioning on sleep habits. 100 part
miskamm [114]

In the research of Professor Nwamabi  the use of air conditioning represents independent variable.

Given 100 participants are randomly selected in a research in which effects of air conditioning on sleep habits is studied.

Dependent variable is the variable whose value is dependent on the other variables like increase in profit and production.

Independent variable is the variable whose value is not dependent on the other variables.

In the research of Professor Nwamabi in which he is examining the effects of air conditioning on sleep habits, use of air conditioning represents independent variable. In this study the effect is on sleep habits means the value of sleep habits will change due to use of air conditioning. It shows that the use of air conditioning is not depending on other variable in the research.

Hence the use of air conditioning represents the independent variable.
