Galina-37 [17]

Answer:

We conclude that garbage collector's average picking is more than four tons of garbage per day.

Step-by-step explanation:

We are given the following information n the question:

First, we design the null and the alternate hypothesis

H_{0}: \mu \leq 4\text{ tons}\\H_A: \mu > 4\text{ tons}

Significance level = 5% = 0.05

P-value = 0.04

  • The p-value is the probability of obtaining the observed results of a test, assuming that the null hypothesis is correct.
  • P values evaluate how well the sample data support that the null hypothesis is true.
  • P-value is a measure or indicator that helps us to know that whether the sample belongs to the population or not.
  • Null hypothesis states that the sample belongs to the population.
  • A high p-values states that the null hypothesis is true ad the sample belongs to the population.ll.
  • A low p-value suggests that sample provides enough evidence that you the null hypothesis is not true and the sample does not belong to the population.
  • We compare p-value to significance level to obtain our result.

Here,

p-value = 0.04 < Significance level = 0.05

Since the p-value is lower than the significance level, we fail to accept the null hypothesis and reject it. That is there were enough evidence to support the fact that sample does not belong to the population and we conclude that garbage collector's average picking is more than four tons of garbage per day.

Approximately how much principal would need to be placed into an account earning 3.575% interest compounded quarterly so that it
Ainat [17]

<u>Answer-</u>

<em>$23377</em><em> must be deposited to get $68000 at the end of 30 years.</em>

<u>Solution-</u>

We know that for compound interest,

A=P(1+\dfrac{r}{n})^{nt}

Where,

A = Future amount = $68,000

P = ??

r = 3.575% annual = 0.03575

n = 4 as interest is compounded quarterly

t = time in year = 30 years

Putting the values,

\Rightarrow 68000=P(1+\dfrac{0.03575}{4})^{4\times 30}

\Rightarrow 68000=P(1.0089375)^{120}

\Rightarrow P=\dfrac{68000}{(1.0089375)^{120}}

\Rightarrow P=23377.45

Therefore, $23377 must be deposited to get $68000 at the end of 30 years.

Okay. The vertex of the point is (0, 0). After the transformation, the vertex becomes (0, 2). For this formula, we don't need the parenthesis. That eliminates A and B. When we move up, we always add, so the formula is g(x) = x² + 2. The answer is D.
