Total frequency = 56.

          Total fx = 1717

          midpoint of 45-49 = 47

          Mean of the data = 30.7

          Median of the data = 31.3

          Mode of the data = 32.5

<h3>What is Mean?</h3>

A measure of central tendency (also referred to as measures of centre or central location) is a summary measure that attempts to describe a whole set of data with a single value that represents the middle or centre of its distribution.

Here, total frequency  ∑f = 5+7+9+11+8+7+5+4

                                    = 56       (option B)

Total fx or ∑fx = 12X4 + 17X5 + 22X7 + 27X8 + 32X11 + 37X9 + 42X7+ 47X5

                        = 48 + 85 + 154 + 216 + 352 + 333 + 294 + 235

                        = 1717               (option B)

The midpoint of the score 45-49 = (45 + 49)/2  

                                                        = 47         (option B)

Mean of the data = ∑fx/ ∑f

                             = 1717 / 56

                             = 30.7                      (option D)

Median of the data = 31.3                (option A)

Mode of the data = 32.5                  (option B)

Thus, Total frequency = 56.

          Total fx = 1717

          midpoint of 45-49 = 47

          Mean of the data = 30.7

          Median of the data = 31.3

          Mode of the data = 32.5

Solve the system y = -x + 7 and y = -0.5(x - 3)2 + 8
arlik [135]

Answer:

The solution of the system is at point (1,6) and (7,0).

Step-by-step explanation:

Given : System of equation y=-x+7 and y=-0.5(x-3)^2+8

To find : Solve the system of equation?

Solution :

We solve the equation graphically as the intersection points give you the solution of the system.

The equation given is one linear and one parabolic.

(1) y=-x+7 is a linear equation in red line passes through (0,7) and (7,0).

(2) y=-0.5(x-3)^2+8 is a parabolic equation in blue line passes through (-1,0) and (7,0)

The intersection point of the equations are (1,6) and (7,0).

<u>Refer the attached figure below.</u>

Therefore, The solution of the system is at point (1,6) and (7,0).

HELPPP PLEASE 30 POINTSS!!! HURRYYY
Gemiola [76]

Answer:

(f \ o \ p)(9) = 4471

Step-by-step explanation:

<h3><em><u>We will assume the black dot between f and p (what we want to find) is a "composition of function".</u></em></h3>

So, it will mean, put the function p into the function f and then evaluate that at the value of s = 9.

So, lets find the composition first:

(f \ o \ p)(s) = 7(s^3-10s)-2\\(f \ o \ p)(s) = 7s^3-70s-2

Now, we put "9" into s and find the value:

(f \ o \ p)(s) = 7s^3-70s-2\\(f \ o \ p)(9) = 7(9)^3-70(9)-2\\(f \ o \ p)(9) = 4471

Please answer my question
hoa [83]

Answer:

3/4

Step-by-step explanation:

Two parts of the wheel are 5 and 8. So 2/8 are the parts you don’t wanna land. That leaves 6 parts open. As a fraction this is 6/8. Simplified, it is 3/4.

There’s a 3/4 chance it will not land on 5 or 8
