The random-number generator on calculators randomly generates a number between 0 and 1. The random variable X, the number generated, follows a uniform probability distribution.
(a) Identify the graph of the uniform density function.
(b) What is the probability of generating a number between 0.01 and 0.34?
(c) What is the probability of generating a number greater than 0.95?

Answers

Answer 1

Using the uniform distribution, we have that:

a) The graph is sketched at the end of this answer.

b) 0.33 = 33% probability of generating a number between 0.01 and 0.34.

c) 0.05 = 5% probability of generating a number greater than 0.95.

An uniform distribution has two bounds, a and b.

The probability of finding a value between c and d is:

[tex]P(c \leq X \leq d) = \frac{d - c}{b - a}[/tex]

The probability of finding a value above x is:

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

In this problem, uniformly distributed between 0 and 1, thus [tex]a = 0, b = 1[/tex].

Item b:

[tex]P(0.01 \leq X \leq 0.34) = \frac{0.34 - 0.01}{1 - 0} = 0.33[/tex]

0.33 = 33% probability of generating a number between 0.01 and 0.34.

Item c:

[tex]P(X > 0.95) = \frac{1 - 0.95}{1 - 0} = 0.05[/tex]

0.05 = 5% probability of generating a number greater than 0.95.

The ratio of boys to girls in school is
11:10. If there are 525 students in the
School, How many boys?

Answers

Answer: 275

How to get it: the ratio is 11:10 , therefore in total there is 21 to the ratio, (11+10), divide 525 by 21 and you get 25. To find out one side of the ratio you x25 by the side of the ratio you need, for this it would be 11x25, which is 275.

Which is the equation of the circle that has a diameter with endpoints located at (0, –3) and (6, 5)?
(x – 6)^2 + (y – 5)^2 = 100
(x – 3)^2 + (y – 1)^2 = 25
x^2 + (y + 3)^2 = 100
(x – 5)^2 + y^2 = 25

Answers

The equation of the circle that has a diameter with endpoints located at (0, –3) and (6, 5) is;

(x – 3)² + (y – 1)² = 25

The midpoint of the diameter of a circle is it's center.

As such; the coordinates of its center are;

x = (0 + 6)

x = 3

y = (-3 + 5)/2

y = 1

The coordinates of the center are then; (3, 1)

The radius of a circle is half the length of the diameter;

Radius, r = d/2

where; d = √(6-0)² + (5-(-3))²

d = √36 + 64

d = √100

d = 10

Therefore, radius, r = 10/2 = 5.

Therefore, the equation of the circle usually takes the form;

(x -f)² + (x -g)² = r²

In this scenario; the equation is;

(x – 3)² + (y – 1)² = 25.

= 17/2 * 9/4

= 153/8

= 19 1/8.

Answer:

₹ 19.125 or ₹ 19 1/8

Step-by-step explanation:

1 kg = ₹ 8 1/2

2 1/4 kg = x

8 1/2 can be written as 8.25

2 1/4 can be written as 2.25

To find x:

Aloysius was 3 times as old as his son 8 years ago. How old is his son now if
their total age is 68 years now?

Answers

9514 1404 393

Answer:

Step-by-step explanation:

8 years ago, both were 8 years younger, so the total of their ages would have been 68 -2×8 = 52. If the ratio of their ages was 1 : 3, then the son's age then was 1/(1+3) = 1/4 of the total. 1/4×52 = 13.

Now, 8 years later, the son's age is 13 +8 = 21.

Then, Aloysius was 3×13 = 39. Now, Aloysius is 39+8 = 47, and the sum of their ages is 21 +47 = 68, as required.

What is Normal Distribution?

A data collection with a normal distribution is put up so that the majority of the values cluster in the middle of the range and the remaining values taper off symmetrically in either direction.

The random variables whose values can locate any unknown value within a defined range are those that follow the normal distribution. for instance, determining the school's student population's height.

Given:

A data is normally distributed with a mean of 5%.

and a standard deviation of 5% .

So, z- score

z(0) = -1

PLEASE ANSWER THESE QUICK I NEED HELP PLEASE ITS ALGEBRA
1. Describe the graph of y = -|x + 4| - 5.

2. Describe how to use the Vertical Line Test and what it can tell us.

Answers

Step-by-step explanation:

1.) y = - |x - 4| - 5 is an absolute value graph, where its vertex occurs at point (4, -5). The general form of the absolute value function is y = a |x – h| + k, where where:

a ≠ 0, and the value of a determines whether the graph opens up or down. If a is between 0 and 1, the graph is wider than the parent function.(h, k ) represents the vertex.

The given absolute value function, y = - |x - 4| - 5 is a downward-facing graph, where it is translated 4 units to the right (as given by the value of h = 4), and 5 units downward (as given by the value of k = 5).

2.) The Vertical Line Test allows us to know whether or not a graph is actually a function. If a vertical line intersects the graph in all places at exactly one point, then the relation is a function. To use the vertical-line test, imagine dragging a ruler held vertically across the graph from left to right. If the graph is that of a function, the edge of the ruler would hit the graph only once for every x -value. If you do this for the given graph, every vertical line intersects the graph in at most one point.

Attached is the graph of the given function, where I performed the Vertical Line Test. As evidenced in the graph, every green vertical line intersects the graph at exactly one point (red dots on the graph). Thus, the graph passed the Vertical Line Test, thereby qualifying as a function.
