The point that is not included in the solution set for the inequality in the graph is (-1, 3).

<h3>How to explain the graph?</h3>

In the information given, (h, k) is the vertex point. In the graph, the vertex point will be (1, 2). The equation will be:

y = a(x + 1)² + 2

By the point of the graph(0, 3) the value of a will be:

3 = a(0 - 1)² + 2

3 = a + 2

a = 3 - 2

a = 1

The equation this becomes:

y = 1(x - 1)² + 2.

y = x² - 2x + 1 + 2

y = x² - 2x + 3

Therefore, the point that is not included in the solution set for the inequality is (-1, 3).

Andrew has a different cookie recipe that makes 28 cookies. He plans to have 21 guests at the party and wants each guest to have

joja [24]

Answer: Since each recipe makes 28 cookies, tripling the recipe would give him 28(3) = 84 cookies.

Step-by-step explanation: <em>Since each recipe makes 28 cookies, tripling the recipe would give him 28(3) = 84 cookies. </em>

<em>Then divide the total number of cookies by the number of guests: 84 21 = 4. Each person would get 4 cookies.</em>

<em>This process can be modeled by the expressions 28(3) ÷ 21 and </em>

<em>. This is because the fraction bar represents division.</em>

Luda [366]

The true statement is as follows "No because she did not use a simple random sample".

<h3>What is random sampling?</h3>

Random sampling is the method to choose the given samples of observation to make assumptions about the population.

It is given that

Population: All tenth-grade girls

Sample: 20 intramural tennis players

The 20 intramural tennis players cannot represent all tenth-grade girls.

This is so because the selection is biased here, and it could not be used to make inferences about the overall population. then she did not use a simple random sample.

Hence, the true statement is (b)
