1. The probability of selecting exactly one tank with high-viscosity material is 0.

2. The probability of selecting at least one tank with high-viscosity material is 1.

3. The probability of selecting exactly one tank with high-viscosity material and exactly one tank with high impurities is 0.25.

1. The probability of selecting exactly one tank with high-viscosity material is calculated by the binomial distribution formula, P(X = n) = (nCx)p^x(1-p)^n-x, where n is the number of trials, x is the number of successes, and p is the probability of success. In this case, n = 4, x = 1, and p = 24/24 = 1. Therefore, P(X = 1) = (4C1)1^1(1-1)^4-1 = 0.

2. The probability of selecting at least one tank with high-viscosity material is calculated by the complement rule, P(X > 0) = 1 - P(X = 0). In this case, P(X > 0) = 1 - (4C0)1^0(1-1)^4-0 = 1.

3. The probability of selecting exactly one tank with high-viscosity material and exactly one tank with high impurities is calculated by the binomial distribution formula, P(X = n) = (nCx)p^x(1-p)^n-x, where n is the number of trials, x is the number of successes, and p is the probability of success. In this case, n = 8, x = 2, and p = 24/24 = 1. Therefore, P(X = 2) = (8C2)1^2(1-1)^8-2 = 0.25.

The correct relationship of the three principles is: The well-ordering principle for the integers is equivalent to strong mathematical induction, and neither is equivalent to weak mathematical induction.

The well-ordering principle for the integers states that every non-empty set of non-negative integers has a least element. Strong mathematical induction is a proof technique that involves proving that a statement is true for a base case, and then assuming that it is true for all cases up to a certain value, and then proving that it must also be true for the next case.

This requires assuming the truth of all cases up to a certain value, which is where the well-ordering principle comes in. Weak mathematical induction is a proof technique that involves proving that a statement is true for a base case, and then assuming that it is true for a particular case, and then proving that it must also be true for the next case.

Weak mathematical induction does not require assuming the truth of all cases up to a certain value, and is therefore weaker than strong mathematical induction.

Step-by-step explanation:

(a)

calculate the lengths using the distance formula

d = \(\sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2 }\)

with (x₁, y₁ ) = J (- 3, - 7 ) and (x₂, y₂ ) = K (3, - 8 )

JK = \(\sqrt{(3-(-3))^2+(-8-(-7))^2}\)

    = \(\sqrt{(3+3)^2+(-8+7)^2}\)

    = \(\sqrt{6^2+(-1)^2}\)

    = \(\sqrt{36+1}\)

    = \(\sqrt{37}\)

repeat with (x₁, y₁ ) = M (8, 3 ) and (x₂, y₂ ) = N (7, - 3 )

MN = \(\sqrt{(7-8)^2+(-3-3)^2}\)

      = \(\sqrt{(-1)^2+(-6)^2}\)

     = \(\sqrt{1+36}\)

     = \(\sqrt{37}\)

repeat with (x₁, y₁ ) = P (- 8, 1 ) and (x₂, y₂ ) = Q (- 2, 2 )

PQ = \(\sqrt{-2-(-8))^2+(2-1)^2}\)

      = \(\sqrt{(-2+8)^2+1^2}\)

Step-by-step explanation:

The approximate 95% confidence interval is (14.69, 18.51).

What is the confidence interval?

A confidence interval is a range of estimates for an unknown parameter in frequentist statistics. The 95% confidence level is the most popular, however other levels, such as 90% or 99%, are occasionally used when computing confidence intervals.

Here, we have

Given:

H₀ : μ = 15

H₁ : μ > 15

The test statistic t = ( x - μ) /(s/√n)

= (16.6 - 15)/(8√70/))

= 1.67

P-value = P(T > 1.67)

= 1 - P(T < 1.67)

= 1 - 0.9503

= 0.0497

At a 5% significance level, since the P-value < α (0.0497 < 0.05), so we should reject H₀.

So at a 5% significance level, there is sufficient evidence to conclude that employees spend more than 15 minutes on average on non-business activities.

The point estimate for the population mean (x) = 16.6

SE = (s/√n) = 8/√70 = 0.9562

At a 95% confidence interval, the critical value is t* = 1.995

The 95% confidence interval for the population mean is

x± t* (s/√n)

= 16.6 ± 1.995 × (8/√70)

= 16.6 ± 1.91

= 14.69, 18.51

Hence, the approximate 95% confidence interval is (14.69, 18.51).

On solving the provided proportionality question we got that, U = 7.72, is rounded off nearest to tenth digit.

We must determine the ratio of the two quantities for each value supplied in order to determine if two quantities are proportionate. The proportionate link between them is evident if their proportions are equal. Their connection is not proportionate if all the ratios are out of balance.

When two quantities or variables are linearly related in mathematics, the term "proportional" is used. Both quantities increase by two times when one increases by two. Each variable decreases in proportion to the other when it falls to 1/100th of its previous value.

Here,

\(\frac{U}{5} = \frac{17}{11} \\\\\)

\(U = \frac{17}{11} X 5\\\)

\(U = \frac{85}{11}\\ U = 7.72\)

A control chart that measures variables measures characteristics that can be measured on a continuum of value like weight and volume.

Control diagrams are a measurable instrument used to screen and control processes over the long haul. They are utilized to follow factors that can be estimated on a consistent scale, like weight, volume, temperature, or time. These factors are not discrete, yet rather fall along a reach or continuum of values. By plotting information over the long haul on a control graph, a cycle can be observed to guarantee that it stays inside a predetermined scope of OK variety. The control diagram gives a visual portrayal of the cycle information, permitting process proprietors to recognize when the interaction is crazy or when it might require remedial activity. Generally, control outlines that action factors assist with guaranteeing the nature of the cycle yield by empowering process proprietors to distinguish and address issues before they bring about deformities or mistakes.

The compounding formula is used to create the quarterly compounding formula. To the nearest cent, the compounded balance is $ \(12,832.27.\)

To reflect the quarterly interest computation as the only change, the interest rate is increased by 4*2.

\(A = P(1 + r/n)(nt)\)

Assume that we have a $  \(10,000\) Initial investment, a 6% yearly interest rate, and a 5-year investment period. We have n = 4 and t = 5 since the interest is compounded every three months.

Plugging in these values, we get:

\(A = 10,000(1 + 0.06/4)(4*5)\)

\(= 10,000(1.015)^20\)

\(= 12,835.72\)

Hence, the final balance is $ \(12,835.72\) to the nearest penny.

If the money is compounded continually, we may use the following formula to determine the balance:

\(A = Pe(rt)\)

With the identical values as before, we obtain:

\(A = 10,000e(0.06 \times5)\)

\(= 10,000e(0.3)\)

\(= 12,832.27\)

Therefore, So the balance, to the nearest cent, is $ \(12,832.27.\)
