factor x out of 7x-4x^2

The expected value of y, rounded to one decimal place, is 5.0.

Here, we have to compute the expected value E(y), we multiply each value of y by its corresponding probability and sum them up.

E(y) = (1 * 0.20) + (5 * 0.30) + (6 * 0.40) + (9 * 0.10)

Calculating the above expression:

E(y) = 0.20 + 1.50 + 2.40 + 0.90

E(y) = 5

Therefore, the expected value of y, rounded to one decimal place, is 5.0.

The expected value of a discrete random variable can be calculated as the weighted average of all its possible values, with the weights being the probabilities of each value.

In order to calculate the expected value, we will need to multiply each value by its corresponding probability and then add up these products:

E(y) = 1 (0.20) + 5(0.30) + 6 (0.40) + 9(0.10)

E(y) = 0.20 + 1.50 + 2.40 + 0.90

E(y) = 5

Therefore, the expected value of y is 5.

Answer:

m=-7/2

Step-by-step explanation:

 (5 • (m + 2) -  m) -  (2m + 3)  = 0

 2m + 7  = 0

3.1      Solve  :    2m+7 = 0

Subtract  7  from both sides of the equation :

                     2m = -7

Divide both sides of the equation by 2:

                    m = -7/2 = -3.500

Answer

5(m+2)-m=2m+3

5m+10-m=2m+3

5m-2m-m=-10+3

3m-m=-10+3

2m=-7

m= -7/2

m= -3.5

Let's set our two numbers as x and y:

When two numbers multiply 25 --> xy = 25

Add to 26 --> x + y =26

The equations:

Now Solve:

Solve for y in the equation 2:

 y = 26 - x <-- equation 3

Plug equation 3's value of y into equation 1

x(26 - x) = 25

-x^2 + 26x - 25= 0

x^2 - 26x + 25 = 0

 (x - 1) (x -25) = 0

Thus say x = 1, then y = 25, it can be either way that x = 25 and y = 1, but our two numbers are 1 and 25

Given that the diameter of circle = twice the radius, the value of x = 4.7.

The diameter of a circle is a segment that divides the circle into two halves.

Diameter = 2(radius of circle).

Given:

Radius of circle = x + 1.5

Diameter = 9 2/5 = 9.4 cm

Therefore:

2(x + 1.5) = 9.4

2x + 3 = 9.4

2x = 9.4

x = 9.4/2

x = 4.7

Therefore, given that the diameter of circle = twice the radius, the value of x = 4.7.

[tex]f(x)=-x^2+11x-28[/tex]

Step-by-step explanation:

We see that the zeroes of the graphed parabola are [tex]x=4[/tex] and [tex]x=7[/tex], which are solutions to [tex]x-4=0[/tex] and [tex]x-7=0[/tex] respectively. We also observe that the parabola opens downward, so the leading coefficient is negative. By multiplying these two factors and negating the result, we can determine the actual function:

[tex]f(x)=-(x-4)(x-7)\\\\f(x)=-(x^2-11x+28)\\\\f(x)=-x^2+11x-28[/tex]

Thus, the quadratic equation represented by the graph is [tex]f(x)=-x^2+11x-28[/tex]

Answer:

No possible answer (unless the equal sign was supposed to be a plus sign, then see answer below)

Step-by-step explanation:

we can simplify the expression like such:

24 + 2x = 2x = 24

As you will notice 2x + 24 cannot equal 2x, or 24.

If the equals sign was a typo and was meant to be a plus sign then the answer is all real numbers.

2(12 + x) can be broken down to (2*12) + (2*x) which equals 2x + 24.

Then this equals the other side of the equation meaning that it doesn't matter what x equals the equation is always equal.

Answer:

h = 16°

Step-by-step explanation:

The total angle of a straight line = 180°.

So we can say that 151° + x = 180°

180° - 151° = x

x = 29°

total angles of a triangle = 180°

∴ 118 + 29 + 2h + 1 = 180

⇒ 148° + 2h = 180°

⇒ 2h = 180° - 148°

⇒2h = 32°

⇒h = 32° ÷ 2

⇒ h = 16°
