Answer:

2+n=?

Step-by-step explanation:

Because we do not know the amount Jared gave him and we do not know the total amount either.

the simplified form of (3x²y³/z³)³ is 27 * x⁶ * y⁹ / z⁹. the correct option is A

To simplify the expression (3x²y³/z³)³, we need to apply the power of a power rule. In this rule, we raise each term inside the parentheses to the power outside the parentheses.

So, let's simplify step by step:

(3x²y³/z³)³ = 3³ * (x²)³ * (y³)³ / (z³)³

Simplifying further:

3³ = 27

(x²)³ = x²⁽³⁾ = x⁶

(y³)³ = y³⁽³⁾ = y⁹

(z³)³ = z³⁽³⁾ = z⁹

Combining all the simplified terms, we have:

27 * x⁶ * y⁹ / z⁹

Therefore, the simplified form of (3x²y³/z³)³ is 27 * x⁶ * y⁹ / z⁹. the correct option is A. This expression represents the original expression after raising each term inside the parentheses to the power of 3 and combining them into a single term.

Answer:

B.

Step-by-step explanation:

AD, the entire segment, is composed of the three segments AB, BC, and CD. In other words:

[tex]AD=AB+BC+CD[/tex]

Since AB=CD, we can substitute:

[tex]AD=CD+BC+CD\\ AD=2CD+BC[/tex]

We know that CD is 9 and BC is 5x. AD is 53. So, substitute:

[tex]53=2(9)+5x[/tex]

Solve for x:

[tex]\begin{aligned} 53&=18+5x \\ 35&=5x \\ 7&=x \end{aligned}[/tex]

The value of x is 7.

Hence, our answer is B.

Graph 1 shown in the figure 1 is the scatter plot that shows a nonlinear association for the data.

When the relationship of the scatter plot does not resemble a straight line then that scatter plot is called a Non-linear scatter plot.

In figure 1, the scatter plot of graph 2, graph 3 and graph 4 can resemble a straight line but the graph 1 does not resemble a straight line.

As the slope of that graph also changes.

So, graph 1 is the scatter plot that shows a nonlinear association for the data.

Complete Question

A sample of 1200 computer chips revealed that 53% of the chips do not fail in the first 1000 hours of their use. The company's promotional literature claimed that more than 50% do not fail in the first 1000 hours of their use. Is there sufficient evidence at the 0.10 level to support the company's claim

Answer:

The decision rule is  

    Reject the null hypothesis

The  conclusion is  

   There is sufficient evidence to conclude that  the company's promotional literature claimed that more than 50% do not fail in the first 1000 hours of their use is correct

Step-by-step explanation:

From the question we told that

   The sample size is  n =  1200

   The significance level is  [tex]\alpha = 0.100[/tex]

   The sample proportion is  [tex]\^ p = 0.53[/tex]

    The null hypothesis  [tex]H_o : p = 0.50[/tex]

     The alternative hypothesis is  [tex]Ha : p > 0.50[/tex]

Generally the test statistics is mathematically represented as

        [tex]z = \frac{\^ p - p }{ \sqrt{\frac{p(1 - p )}{n} } }[/tex]

=>      [tex]z = \frac{ 0.53 - 0.5 }{ \sqrt{\frac{0.50 (1 - 0.50)}{1200} } }[/tex]  

=>      [tex]z = 2.078[/tex]

From the z table  the area under the normal curve to the right corresponding to  2.078  is  

      [tex]P(Z > 2.078 ) = 0.018855[/tex]

So

     [tex]p-value = 0.018855[/tex]

Generally the value obtained we see that  [tex]p-value < \alpha[/tex]  , Hence  

The decision rule is  

    Reject the null hypothesis

The  conclusion is  

   There is sufficient evidence to conclude that  the company's promotional literature claimed that more than 50% do not fail in the first 1000 hours of their use is correct

Answer:

HP=11

Step-by-step explanation:

Now that we have \blueE{HP}HPstart color #0c7f99, H, P, end color #0c7f99, we can find HDHDH, D.

\begin{aligned} HD&=\blueE{HP}+DP \\\\ &=\blueE{2}+9 \\\\ &=11 \end{aligned}

HD

​

=HP+DP

=2+9

=11

​

Using the AAA similarity theorem, the length of segment HD in the diagram given is: 11 units.

If all corresponding angles of two  triangles are congruent, then, they are similar triangles, based on the AAA similarity theorem.

ΔPOH ~ ΔPID by AAA similarity theorem.

Therefore, their corresponding sides would be proportional. Thus:

PH/PD = PO/PI

Substitute

PH/9 = 6/27

PH = (9 × 6)/27

PH = 2

HD = 2 + 9

HD = 11 units.

Answer: whole number is 5 and remainder is 2

Step-by-step explanation:

six goes into 32 5 times to get 30

32-30=2

Answer:

Explained below.

Step-by-step explanation:

According to the Central limit theorem, if from an unknown population large samples of sizes n > 30, are selected and the sample proportion for each sample is computed then the sampling distribution of sample proportion follows a Normal distribution.

The mean of this sampling distribution of sample proportion is:

[tex]\mu_{\hat p}=p[/tex]

The standard deviation of this sampling distribution of sample proportion is:

[tex]\sigma_{\hat p}=\sqrt{\frac{p(1-p)}{n}}[/tex]

A random sample of n = 658 items is sampled randomly from this population.

As the sample size is large, i.e. n = 658 > 30, the Central limit theorem can be applied to approximate the sampling distribution of sample proportion by a Normal distribution.

Compute the mean and standard deviation as follows:

[tex]\mu_{\hat p}=0.61\\\\\sigma_{\hat p}=\sqrt{\frac{0.61(1-0.61)}{658}}=0.019[/tex]

(a)

Compute the probability that the sample proportion is greater than 0.63 as follows:

[tex]P(\hat p>0.63)=P(\frac{\hat p-\mu_{\hat p}}{\sigma_{\hat p}}>\frac{0.63-0.61}{0.019})\\\\=P(Z>1.05)\\\\=1-P(Z<1.05)\\\\=1-0.85314\\\\=0.14686\\\\\approx 0.1469[/tex]

(b)

Compute the probability that the sample proportion is between 0.60 and 0.66 as follows:

[tex]P(0.60<\hat p<0.66)=P(\frac{0.60-0.61}{0.019}<\frac{\hat p-\mu_{\hat p}}{\sigma_{\hat p}}<\frac{0.66-0.61}{0.019})\\\\=P(-0.53<Z<2.63)\\\\=P(Z<2.63)-P(Z<-0.53)\\\\=0.99573-0.29806\\\\=0.69767\\\\\approx 0.6977[/tex]

(c)

Compute the probability that the sample proportion is greater than 0.592 as follows:

[tex]P(\hat p>0.592)=P(\frac{\hat p-\mu_{\hat p}}{\sigma_{\hat p}}>\frac{0.592-0.61}{0.019})\\\\=P(Z>-0.95)\\\\=P(Z<0.95)\\\\=0.82894\\\\\approx 0.8289[/tex]

(d)

Compute the probability that the sample proportion is between 0.57 and 0.60 as follows:

[tex]P(0.57<\hat p<0.60)=P(\frac{0.57-0.61}{0.019}<\frac{\hat p-\mu_{\hat p}}{\sigma_{\hat p}}<\frac{0.60-0.61}{0.019})\\\\=P(-2.11<Z<-0.53)\\\\=P(Z<-0.53)-P(Z<-2.11)\\\\=0.29806-0.01743\\\\=0.28063\\\\\approx 0.2806[/tex]

(e)

Compute the probability that the sample proportion is less than 0.51 as follows:

[tex]P(\hat p<0.51)=P(\frac{\hat p-\mu_{\hat p}}{\sigma_{\hat p}}<\frac{0.51-0.61}{0.019})\\\\=P(Z<-5.26)\\\\=0[/tex]
