Three different methods for assembling a product were proposed by an industrial engineer. To investigate the number of units assembled correctly with each method, 30 employees were randomly selected and randomly assigned to the three proposed methods in such a way that each method was used by 10 workers. The number of units assembled correctly was recorded, and the analysis of variance procedure was applied to the resulting data set. The following results were obtained: SST = 10,800; SSTR = 4560.
1. Set up the ANOVA table for this problem (to 2 decimals, if necessary).

Answer:

  22.3 ft

Step-by-step explanation:

The height of the portion of the pole that is above Ella's eyes can be found using the tangent function.

 Tan = Opposite/Adjacent

  tan(25°) = (height above eyes)/(36 ft)

  height above eyes = (36 ft)·tan(25°) ≈ 16.8 ft

Then the height of the flagpole is ...

  5.5 ft + 16.8 ft = 22.3 ft

The flagpole is 22.3 feet high.

Answer:

[tex]Rate = 19[/tex]

Step-by-step explanation:

Given

[tex]y = x^2 + 3x[/tex]

[tex]1 \le x \le 15[/tex]

Required

Determine the average rate of change

This is calculated as:

[tex]Rate = \frac{f(b) - f(a)}{b - a}[/tex]

Where

a = 1 and b = 15

So, we have:

[tex]Rate = \frac{f(15) - f(1)}{15 - 1}[/tex]

[tex]Rate = \frac{f(15) - f(1)}{14}[/tex]

Solve f(15):

[tex]f(15) = 15^2 + 3*15 = 270[/tex]

Solve f(1)

[tex]f(1) = 1^2 + 3*1 = 4[/tex]

So:

[tex]Rate = \frac{f(15) - f(1)}{14}[/tex]

[tex]Rate = \frac{270- 4}{14}[/tex]

[tex]Rate = \frac{266}{14}[/tex]

[tex]Rate = 19[/tex]

Answer:

By the time her grandson turns 21, the account will be worth $ 8,554.27.

Step-by-step explanation:

Given that at the time of her grandson's birth, a grandmother deposits $ 3000 in an account that pays 5% compounded monthly, to determine what will be the value of the account at the child's twenty-first birthday, assuming that no other deposits or withdrawals are made during this period, the following calculation must be performed:

X = 3,000 (1 + 0.05 / 12) ^ 21x12

X = 8,554.27

Thus, by the time her grandson turns 21, the account will be worth $ 8,554.27.

Answer:

0.345

Step-by-step explanation:

hits/at-bats = 345/1000 = 0.345

The probability of a hit, any particular time he goes to bat. is 0.345.

The problem does not request any particular format, so 0.345 is a perfectly good answer.

In baseball, that is called a 'batting average', and is actually expressed that way - as a decimal - in a player's statistics.

On the other hand, if we did want to express the probability as a percentage, we would do this:  

0.345 * 100% = (0.345 * 100) % = 34.5 %

Answer:

Based upon past experience, Barry expects no overdrafts. He expects no 2nd copies of statements. Barry estimates that he will use network ATMs about 5 times a month with either bank. Barry decides in the end to choose EECU. Assuming that both banks provide the necessary services equally well, and based upon the tables of fees given above, how much can Barry reasonably expect to save annually by choosing EECU in this case over E-town bank?

a.  $72

b.   $78 <<<CORRECT

c.   $144

d.   $24

Step-by-step explanation:

October 2021 EDGE

Barry can expect to save a total of $144 per year by choosing EECU over E-town bank.

Option C is the correct answer.

A bank account is a financial account that is opened with a bank or financial institution, which enables individuals or businesses to deposit, withdraw, or transfer money. It is a safe and convenient way to manage money and conduct financial transactions.

We have,

To calculate how much Barry can save annually by choosing EECU over E-town bank, we need to compare the fees charged by both banks for the services Barry expects to use.

According to the tables of fees given above:

- E-town bank charges $2.50 per out-of-network ATM transaction, while EECU charges $1.00.

- E-town bank charges $1.50 per month for paper statements, while EECU charges $0.00.

Based on Barry's expectations, here's how much he can expect to pay annually for these services with each bank:

Out-of-network ATM transactions:

Barry expects to use network ATMs about 5 times a month.

With E-town bank, that would cost him 5 x $2.50 x 12 = $150 per year.

With EECU, that would cost him 5 x $1.00 x 12 = $60 per year.

So Barry can save $150 - $60 = $90 per year by choosing EECU over E-town bank for ATM transactions.

Paper statements:

Barry expects no 2nd copies of statements, so this cost is irrelevant. However, if Barry received paper statements, E-town bank would charge him $1.50 per month, or $18 per year. EECU, on the other hand, does not charge any fee for paper statements, so Barry would save $18 per year by choosing EECU over E-town bank for this service.

So,

By choosing EECU over E-town bank, Barry can expect to save a total of $90 + $18 = $108 per year.

Thus,

Barry can expect to save a total of $144 per year by choosing EECU over E-town bank.

Answer:

-2√5

Step-by-step explanation:

You can simplify √20 into 2√5 by taking out a 4 out of the 20.

Then simplify √80 by taking out 16 and turning into 4√5

2√5 - 4√5 = -2√5

The limit does not exist at the jump discontinuity at x = -2.

From the left, the green-ish curve approaches 4; from the right, the orange curve approaches 6. These one-sided limits are not equal, so the two-sided limit does not exist.

A limit of a function does not exist at a point x is the limit of f(x) approaching x to the left is different of the limit of f(x) approaching x to the right.

Using this concept, we find that the limit does not exist at c = -2.

Points we need to verify:

Points in which there are changes in the definition of the function, which are:

x = -4, -2, 2, 4

At x = -4

The definitions are bunched together, so the lateral limits are the same, and the limit exists.

At x = -2

As the function approaches x = -2 to the left(x < -2), its value is close to 4, so the limit is 4.

As the function approaches x = -2 to the right(x > -2), its value is close to 6, so the limit is 6.

Since the lateral limits are different, for c = 2, the limit does not exist, and this is the correct answer.

At x = 2

The lateral limits are the same, the only thing that changes is the definition of the function at x = 2, which does not affect the limit, which exists.

At x = 4

The definitions are bunched together, so the lateral limits are the same, and the limit exists.
