There’s a 30% difference between the percent of increase and percent of decrease. There is a 50% increase when it goes from 30 to 45. And a 20% decrease from 45 to 36.

Answer:

30%

Step-by-step explanation:

The increase was 15/30 = 50%,

The decrease was 9/45 = 20%.

50% - 20% = 30%

Why is the vertex of vertex form y=a(x-h)^2+k (h,k) rather than (-h,k)? If that was y=2(x-5)^2+6, the vertex would be at (5,6) w
Sindrei [870]

Answer:

  (5, 6) is (h, k)

Step-by-step explanation:

Vertex form is an instance of the transformation of parent function f(x) = x². It is vertically scaled by a factor of 'a', and translated so the vertex is point (h, k). That is, the transformed vertex is h units right and k units up from that of the parent function (0, 0).

Parent:

  f(x) = x^2

Transformed:

  f(x) = a(x -h)^2 +k

__

When you compare the form to your specific instance, you need to pay attention to what it is that you're comparing. As the attachment shows, ...

  • a = 2
  • -h = -5   ⇒   h = 5
  • k = 6

Hence the vertex is (h, k) = (5, 6). The second attachment shows this on a graph.

2. What is the external probability of rolling a 4
Nataly_w [17]

Answer:

2. 1- Experimental probability of rolling a 4 = 40%

3. 2- Theoretical probability is 3%  greater than experimental probability.

Step-by-step explanation:

Experimental probability of rolling a 4 = 100 × \frac{8}{20}

                                                                  = 100 × 0.4

                                                                  = 40%

Experimental probability of getting at least one tail  = \frac{72}{100}

                                                                                    = 0.72

Theoretical probability of getting at least one tail  = \frac{3}{4}

                                                                                  = 0.75

Theoretical probability is 3%  greater than experimental probability.
