Answer:

A because theyare collecting data and because it is written down.

Step-by-step explanation:

A. Asking voters whom they will vote for and D. Weighing wrestlers are examples of data collecting.

Given that,

To determine two activities are examples of data collecting.

Statistic is the study of mathematics that deals with relations between comprehensive data.

Here,
The act of acquiring and analyzing data on certain variables in an established system allows one to analyze results and respond to pertinent inquiries. In all academic disciplines, including the physical and social sciences, the humanities, and business, data collecting is a necessary component of research.
So, asking voters whom they will vote for and  Weighing wrestlers are two examples of data collecting.

Thus, A. Asking voters whom they will vote for and D. Weighing wrestlers are examples of data collecting.

3 + 4 > 9

Step-by-step explanation:

Now, when we have 3 sides of a triangle, the sum of the length of any two sides must be greater than the third side

Thus, we have that;

3 + 4 > 9

This is because the above is impossible

Others are quite possible mathematical expressions

Step-by-step explanation:

The midpoint of a segment

Given points C(xc,yc) and B(xb,yb), the coordinates of the midpoint M can be found knowing that:

[tex]\overline{CM} = \overline{ MB}[/tex]

Applying that relation in both axes separately, we can write:

[tex]\displaystyle x_m=\frac{xc+xb}{2}[/tex]

[tex]\displaystyle y_m=\frac{yc+yb}{2}[/tex]

Knowing the coordinates of the midpoint and B, we can find the coordinates of the other extreme C solving both equations for the required variable:

[tex]x_c=2x_m-x_b[/tex]

[tex]y_c=2y_m-y_b[/tex]

Plugging in the known values: M=(-1,1) and B=(3,4):

[tex]x_c=2*(-1)-3=-2-3=-5[/tex]

[tex]y_c=2*1-4 = 2-4=-2[/tex]

The coordinates of C are (-5,-2)

The function f(x) = |x + 1| – 3 is represented by the graph.

In the graph of an absolute function given by (x - a) +b, the vertex is given by (a, -b)

Let's take the first function, f(x) = |x – 1| + 3. Its vertex is given by (1, 3) by using the rule.

Now let's take the second function, f(x) = |x + 1| - 3. It's vertex is given by (-1, -3) by using the rule.

Now let's take the third function, f(x) = |x - 1| - 3. It's vertex is given by (1, -3) by using the rule.

Now let's take the fourth function, f(x) = |x + 1| + 3. It's vertex is given by (-1, 3) by using the rule.

From this, we can see that the second function has a matching vertex.

Therefore, we have found that the absolute function f(x) = |x + 1| – 3 is represented by the graph.

39 MPH

Step-by-step explanation:

       d  =  rt

13 times 3,

20x3=60.

60=1 hour

13M = every 20m

60 divided by 20 =3.

13 times 3 = 39.

39MPH

Kayla is driving at 39 miles per hour.

The average is calculated as the product of all values divided by all possible values. It can also be described as mean. The mean in statistics is the average value for the particular sample or collection of data. It is determined by dividing the total number of observations by the total number of observations.

Given:

Kayla drove 13 miles in 20 minutes.

To find the average rate in miles per hour:

Miles / hour

= 1 / 1

Multiply by 3 to the rate,

So, 13 x 3 mils in 3 x 20 minutes.

39 miles per hour.

Therefore, the average rate is at 39mph.

======================================================

Explanation:

Recall that vertex form is

y = a(x-h)^2 + k

where (h,k) is the vertex. We want the vertex to be (-3,0) which means that h = -3 and k = 0 must be the case.

Plug those values in to get

y = a(x-h)^2 + k

y = a(x-(-3))^2 + 0

y = a(x+3)^2

Now we need the value of 'a', which determines two things

To determine 'a', we'll use the other point (-5,-4).

So we'll plug in x = -5 and y = -4 and solve for 'a'

y = a(x+3)^2

-4 = a(-5+3)^2

-4 = a(-2)^2

-4 = a(4)

-4 = 4a

4a = -4

a = -4/4

a = -1

The equation y = a(x+3)^2 updates to y = -1(x+3)^2 which simplifies to the final answer y = -(x+3)^2. The answer is choice D.

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

As a check, plugging x = -5 should lead to y = -4

y = -(x+3)^2

y = -(-5+3)^2

y = -(-2)^2

y = -(4)

y = -4

This helps confirm the answer.

I'll let you check to see if (-3,0) is on this graph. Plugging in x = -3 should lead to y = 0.
