Answer:

D. No, he chose members that were not part of the population

Step-by-step explanation:

A random sample is a sampling technique in which each sample has an equal chance of being chosen. For example, blindly selecting five names from a hat filled with named sheets of paper is a random sample.

Daniel's sample is not random because each sample did not have an equal probability of being chosen. All names he does not recognize are immediately eliminated from being chosen. With this, we can eliminate choices A and B.

Daniel did not chose names from the town he was collecting data for. He chose ones from his own neighborhood. It wasn't in the population he was focusing on.

Therefore, the best answer is D.

hope this helps :)

Suppose that a fashion company determines that the​ cost, in​ dollars, of producing x cellphone cases is given by ​C(x)equalsneg
Semenov [28]

Answer:

(a)$29.95

(b)A

Step-by-step explanation:

The​ cost, in​ dollars, of producing x cellphone cases is given by:

C(x)=-0.05 x^2+55 x.

We are required to evaluate: \dfrac{C(251)-C(250)}{251-250}

C(251)=-0.05(251)^2+55(251)=10654.95\\C(250)=-0.05(250)^2+55(250)=10625\\\text{Therefore:}\\\\\dfrac{10654.95-10625}{251-250}=29.95

\dfrac{C(251)-C(250)}{251-250}=\$29.95

The value calculated above represents the additional cost to produce one more item after making 250 items.

Read the excerpt from The Land.
babunello [35]

From the conversation it can be inferred that Paul's approach to getting on the horse is methodical (option c).

<h3>What is methodical behavior?</h3>

A methodical attitude or behavior refers to the preference of people to use an organized method and sequences to perform an activity correctly.

According to the above, it can be inferred that Paul behaves in a methodical manner because he prefers to relate to the horse slowly and in a controlled manner before proceeding to mount it.

Explain how to find the vertex of 2x^2+12x+16
Elina [12.6K]

The vertex form:

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

Use (a+b)^2=a^2+2ab+b^2\qquad(*)


2x^2+12x+16=2(x^2+6x)+16=2(x^2+2(x)(3))+16\\\\=2(\underbrace{x^2+2(x)(3)+3^2}_{(*)}-3^2)+16=2((x+3)^2-9)+16\\\\=2(x+3)^2+(2)(-9)+16=2(x+3)^2-18+16\\\\=\boxed{2(x-(-3))^2-2}\to h=-3,\ k=-2

<h3>Answer: (-3, -2).</h3>

Other method:

f(x)=ax^2+bx+c\\\\vertex:(h,\ k)\\\\h=\dfrac{-b}{2a},\ k=f(h)

We have

f(x)=2x^2+12x+16\\\\a=2,\ b=12,\ c=16

Substitute:

h=\dfrac{-12}{(2)(2)}=\dfrac{-12}{4}=-3\\\\k=f(-3)=2(-3)^2+12(-3)+16=2(9)-36+16=18-36+16=-2

<h3>Answer: (-3, -2).</h3>
