Answer:

19/72

Step-by-step explanation:

To calculate the probability that a randomly-chosen child from this group likes either Chess or Swimming but not Football?

We already know the number that liked chess only which is 10, we have to solve for those that liked swimming only which is

8+7+16+x = 40

x which represent swimming only is

40-31 = 9

Thus probability = 10/72 + 9/72 = 19/72

Hi Troppic20Pdge32,

-2(6 + s) ≥ -15 - 2s (All Real Numbers)

3s + 6 ≤ -5(s + 2) (s ≤ -2)

4/3s - 3 < s + 2/3 - 1/3s (s < 5 1/2)

Hope This Helps!

Four transformations of the function f(x) are given below. For each transformation, drag the graph that shows the results of tha
anzhelika [568]

The graph that has been drag into the box in the image attached are the options that shows the results of that transformation.

<h3>What is the Function transformation about?</h3>

Note that there are 4 types of function transformations which are are:

  • Dilation
  • Translation
  • Rotation
  • Reflection

Therefore, The function above is known to have passed through the following points

(1,1) and (0,-1)

The graphs of the functions

(a) Function g(x)

The equation of the function is given as: g (x) = 2 + f (x)

This implies that f(x) is said to be translated up by 2 units.

The graph that shows this is graph (b)

(b) Function h(x) = f (x + 2)

This implies that f(x) is translated left by 2 units.

The graph that shows this is graph (e)

(c) Function k(x)  = f (x) -2

This implies that f(x) is translated down by 2 units.

The graph that shows this is graph (c)

(d) Function m(x) =  f (x - 2)

This implies that f(x) is translated right by 2 units.

The graph that depicts this is graph (f)

Therefore,  The graph that has been drag into the box in the image attached are the options that shows the results of that transformation.

Answer:

y = (2/1)x + 7

Step-by-step explanation:

First I found the slope using the slope formula (which was 2/1)

Then I used that slope to find the y-intercept (which was 7)

Then I put in an equation

Have a great day!
