How many solutions are there to the equation 11x+25=7x+15

Answers

Just one 11x+25=7x+15 11x - 7x = 15 -25 4x = -10 x = -10/4 x = -5/2

There is only one solution for this equation which is x = -2.5 11x+25=7x+15 11x+25-7x=15 11x-7x=15-25 4x= -10 x = -10/4 x = -5/2 x = -2.5

The table gives the probability distribution of the annual rate of return on the stock of MNP Company, Inc.

The expected value of the rate of return is ______%.

Answers

Answer: The expected value of the rate of return is 23.5%.

Step-by-step explanation:

Since we have given that

Annual Return Probability

15% 0.2

20% 0.4

30% 0.3

35% 0.1

We need to find the expected value of the rate of return:

As we know the formula for "Expected value ": $E(x)=\sum xp(x)$

So, it becomes,

$E(X)=15* 0.2+20* 0.4+30* 0.3+35* 0.1=23.5\%$

Hence, the expected value of the rate of return is 23.5%.

Calculation:
15%*0.2 + 20%*0.4 + 30%*0.3 + 35%*0.1 = 23.5%

Answer:
The expected value of the rate of return is 23.5%

Function : y=4 sin(3x)-2Determine the period of the function. How is it related to the question?

Determine the midline of the function. How is it related to the question?

___________________if this function even or odd? Explain how you know

Describe the transformations from y = sin (x)

Answers

So the 4 represents the amplitude of the function. We can also see that because it is a positive number, the graph is even. ⁽⁽The number before the graph type (Sin or Cos) always represents the amplitude. The amplitude is how many units the graph travels up and down from the midline.
The -2 is the midline. This means that the midline is at -2 on the Y-axis. To find the max and min, you then add the amplitude to find the maximum, and subtract to find the minimum. [-6. 2]
To find the period, you divide 2π by the term in front of x. In this case, it's 3, so we do 2π/3. This cannot be simplified further, but in degrees this equals 120°. This means that, with the question asking for 2 full cycles, that the graph will go through 2 full cycles in 240°

Hope this helps, sorry i couldn't sketch the graph for you

PLEASE ANSWER ASAP!!! TIMED!!Finding which number supports the idea that the rational numbers are dense in the real numbers?

A. a fraction between π/2 and π/3
B. an integer between –11 and –10
C. a whole number between 1 and 2
D. a terminating decimal between –3.14 and –3.15

Answers

Using the concept of dense numbers, it is found that the correct option is:

A. a fraction between π/2 and π/3

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

The rational numbers are dense in the real numbers because all irrational numbers can be closely approximated to a rational.
There are no integers between -11 and -10, neither there are whole numbers between 1 and 2, thus, options B and C are incorrect.
Terminating decimals between -3.14 and -3.15, such as -3.141, are rational numbers, so it does not show the density, and thus, option D is incorrect.
$(\pi)/(2)$ and $(\pi)/(3)$ , just as $\pi$ , are non-terminating decimals, thus they are irrational numbers. However, through rounding, all can be approximated to a rational number, and thus, it shows that rational numbers are dense in the real numbers, being the correct option.

A similar problem is given at brainly.com/question/17405059

Answer:

A terminating decimal between -3.14 and -3.15

Step-by-step explanation:

A natural number includes non-negative numbers like 5, 203, and 18476.

It is encapsulated by integers, which include negative numbers like -29, -4, and -198.

Integers are further encapsulated by rational numbers, which includes terminating decimals like 3.14, 1.495, and 9.47283.

By showing a terminating decimal between -3.14 and -3.15, you are showing that rational numbers include integers (because integers include negative numbers)
