Answer:

Option D. The sequence is not arithmetic because the terms do not have a common difference.

Step-by-step explanation:

We are given  points in a graph as:

             x              y         common difference

             1               1    

             2              4            4-1=3

             3               9           9-4=5

             4              16           16-9=7

             5              25          25-16=9

Clearly from the set of values that are given in the graph we could observe that the function that is formed using these set of values is:

y=f(n)=n² where n=1,2,3,4,5,.....

Hence, the following sequence is not an arithmetic sequence as the common difference is different.

( Common difference is the difference in the y-value  from it's preceding y-value)

Hence, option: D is the true option.

D. The sequence is not arithmetic because the terms do not have a common difference.

Sphinxa [80]

Answer:

1

Step-by-step explanation:

Using the rules of exponents

(a^m)^{n} = a^{mn}

a^{m} × a^{n} = a^{(m+n)}

Given

(\frac{1}{x^{(a-b)}) } ^{a+b} × (\frac{1}{x^{b+a}) } ^{b-a}

= \frac{1}{x^{(a-b)(a+b)} } × \frac{1}{x^{(b+a)(b-a)} }

= \frac{1}{x^{(a^2-b^2)} } × \frac{1}{x^{(b^2-a^2)} }

= \frac{1}{x^{(a^2-b^2+b^2-a^2)} }

= \frac{1}{x^{0} }

= \frac{1}{1}

= 1

A manufacturer of salad dressings uses machines to dispense liquid ingredients into bottles that move along a filling line. The
KonstantinChe [14]

Answer:

Step-by-step explanation:

From the given information:

The null hypothesis is:

H_o: \mu = 8

The alternative hypothesis is:

H_1 : \mu \ne 8

The sample size n = 35

Sample mean = 7.91

variance = 0.03

Standard deviation = \sqrt{0.03}  = 0.173

The t-test statistics is computed as:

t = \dfrac{\bar x - \mu}{\dfrac{s}{\sqrt{n}}}

t = \dfrac{7.91 -8}{\dfrac{0.1732}{\sqrt{35}}}

t = \dfrac{-0.09}{\dfrac{0.1732}{5.916}}

t = - 3.0741

Degree of freedom:

df = n - 1

df = 35 - 1

df = 34

Level of significance = 1 - C.I

= 1 - 0.99

= 0.01

The t_{critical} value for the two-tailed test at 0.01 is within the rejection region:

t_{critical} = -2.728 \ and \ 2.728

Decision rule: To reject H_o if  t< -2.728 \ or \ t > 2.728

As t_{statistics} fails the rejection region, we reject H_o

Conclusion: There is sufficient evidence to believe that the machine will not dispense 8 ounces & and it must be stopped for repairs.
