I need help with just a and b for question 5

Answer:

For first question, there is 12 marbles at first. So the probability of choosing blue marble is 3/12=1/4. Then marbles are not replaced, the total number is 11. The probability of choosing red is 5/11. So the finally answer is (1/4)*(5/11)=5/44. The same method for second question. Need to notice that you have already choose 1 white marble, so the number of white marble also changed. The answer is (4/12)*(3/11)=1/11.

Step-by-step explanation:

The probability of selecting 2 blue marbles without replacement will be 1/66.

Its simple notion is that something will most likely occur. The favorable event's proportion to the overall number of occurrences.

There are 4 white marbles, 6 red marbles, and 2 blue marbles.

Once a marble is selected, it is not replaced.

Then the total number of the marbles will be

Total marbles = 4 + 6 + 2

Total marbles = 12

Then the probability of selecting 2 blue marbles without replacement will be

P = 2/12 x 1/11

P = 2/132

P = 1/66

Answer:

Your computer sends a request for the file to a Web server, and the Web server sends back a response.

Step-by-step explanation:

Using the uniform distribution, it is found that there is a 0.0833 = 8.33% probability that the request is received by this server within the first 5 minutes (300 seconds) after the hour.

----------------------------------

An uniform distribution has two bounds, a and b.

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

[tex]P(X < x) = \frac{x - a}{b - a}[/tex]

The probability distribution of Y can be modeled by a uniform density  curve on the interval from 0 to 3600 seconds, thus [tex]a = 0, b = 3600[/tex].

Probability in the first 5 minutes(300 seconds) is:

[tex]P(X < 300) = \frac{300 - 0}{3600 - 0} = 0.0833[/tex]

0.0833 = 8.33% probability that the request is received by this server within the first 5 minutes (300 seconds) after the hour.

Answer:

471.25

Step-by-step explanation:

A volume of a box is equal to length x width x height (abbreviated lwh). The given was: 14 & 1/2 inches long, 5 inches high, and 6 1/2 inches wide. So, all you have to do is multiply the given (I know it sounds too easy, but that's it):

14.5 * 5 * 6.5 = 471.25

So, the volume of the box is 471.25 inches cubed.

The original price was £52 if the t-shirt increased in price by 1/4. After the increase, it was priced at £65.

Fraction number consists of two parts, one is the top of the fraction number which is called the numerator and the second is the bottom of the fraction number which is called the denominator.

The question is incomplete.

Please refer to the picture for the complete question.

We have:

A t-shirt increased in price by 1/4. After the increase, it was priced at £65.

Let's suppose the original price was x

(1 + 1/4)x = 65

(1 + 0.25)x = 65

1.25x = 65

x = £52

Thus, the original price was £52 if the t-shirt increased in price by 1/4. After the increase, it was priced at £65.

Answer:

We conclude that the 12x is the required expression that is equivalent to 7x + 4x + x and has only one term.

Step-by-step explanation:

Given the expression

[tex]7x+4x+x[/tex]

The current expression has three terms such as 7x, 4x, and x.

The current expression can be further simplified such as

[tex]7x+4x+x[/tex]

Add similar elements:  [tex]7x+4x+x=12x[/tex]

[tex]=12x[/tex]

Thus, the given expression [tex]7x+4x+x[/tex] can be expressed as the only one term such as [tex]12x[/tex].

i.e. [tex]7x+4x+x=12x[/tex]

Therefore, we conclude that the 12x is the required expression that is equivalent to 7x + 4x + x and has only one term.
