We can see here that the probability that the password does not have repeated letters, expressed to the nearest tenth of a percent is = 9.8%.

Probability is a measure of how likely an event is to happen. It is expressed as a number between 0 and 1, where 0 means the event is impossible and 1 means the event is certain.

The probability of an event can be calculated using the following formula:

Probability = Favorable Outcomes / Total Outcomes

The number of possible passwords is:

26 × 26 × 26 × 26 × 26 × 26  = 308,915,776.

The number of passwords with no repeated letters is

26P6 = 30,260,000.

The probability of a password having no repeated letters is

= 30,260,000 / 308,915,776 = 0.09779 = 9.78%.

The circle's circumference is approximately 106.81 centimeters.

Explanation:

The formula for the circumference of a circle is C = 2πr, where C is the circumference, π is pi (approximately 3.14), and r is the radius of the circle.

So, for a circle with a radius of 17 centimeters, its circumference can be found by:

C = 2πr

C = 2 x 3.14 x 17

C ≈ 106.81 cm

Therefore, the circumference of the circle is approximately 106.81 centimeters.

Absolute value is defined as

\(|x| = \begin{cases}x & \text{if }x\ge0 \\ -x&\text{if }x<0\end{cases}\)

By this definition, we have

\(|2x-3| = \begin{cases} 2x-3 &\text{if }2x-3 \ge0 \\ -(2x-3) &\text{if }2x-3<0\end{cases}\)

or, after some simplifying,

\(|2x-3| = \begin{cases} 2x-3 &\text{if }x \ge\frac32 \\ 3-2x &\text{if }x<\frac32\end{cases}\)

So a = 3/2.

If x < 3/2, we get the second case:

\(f_1 = 1 + |2x-3| \\\\ f_1 = 1 + (3-2x) \\\\ \boxed{f_1 = 4 - 2x}\)

If x ≥ 3/2, we get the first case:

\(f_2 = 1 + |2x-3| \\\\ f_2 = 1 + (2x-3) \\\\ \boxed{f_2 = 2x-2}\)

The approximate location of the dolphin is 155 feet as it moves at the rate of 6.2 feet per second.

Answer:

d = 1.46 m

Step-by-step explanation:

We'll begin by obtaining the relationship between the force (F) and the distance (d). This can be obtained as follow:

From the question given above,

F is inversely proportional to square of d. This can be written as:

F ∝ 1/d²

F = K/d²

Cross multiply

K = Fd²

But:

Force (F) = 0.006 N

Distance (d) = 4 m

Constant (K) =?

K = Fd²

K = 0.006 × 4²

K = 0.006 × 16

K = 0.096 Nm²

Therefore, the relationship between the force (F) and the distance (d) is:

F = K/d²

F = 0.096 / d²

Finally, we shall determine the distance when the force is 0.045 N. This can be obtained as follow:

Force (F) = 0.045 N

Constant (K) = 0.096 Nm²

Distance (d) =?

F = K/d²

0.045 = 0.096 / d²

Cross multiply

0.045 × d² = 0.096

Divide both side by 0.045

d² = 0.096 / 0.045

Take the square root of both side.

d = √(0.096 / 0.045)

d = 1.46 m.

The shape that represents the sample mean of the 81 students who are selected is; Approximately normal

When a distribution of data is defined as skewed, it means that it does not take the normal distribution's bell shape. Rather, it tends to distort with values either to the left or right of the center of the data.

Now, the Central Limit Theorem states specifically that the distribution of sample mean is normally distributed. It goes further to state that if the population values from which the sample originates is not normally distributed, the sample distribution will be normal. This effect will lead to  increases as sample size increases.

Thus, we can conclude that the shape is normally distributed

The Operating income is $172,500.

To calculate the margin of safety, contribution margin ratio, and operating income, we need to use the given information.

a. Margin of Safety:

Margin of Safety = Actual Sales - Break-even Sales

Given that the break-even point is at $750,000 in sales revenue and actual sales are $1,100,000, we can calculate the margin of safety:

Margin of Safety = $1,100,000 - $750,000 = $350,000

Therefore, the margin of safety is $350,000.

b. Margin of Safety as a Percentage of Sales:

Margin of Safety Percentage = (Margin of Safety / Actual Sales) * 100

Using the values from the previous calculations:

Margin of Safety Percentage = ($350,000 / $1,100,000) * 100 = 31.82%

Therefore, the margin of safety expressed as a percentage of sales is approximately 31.82%.

c. Contribution Margin Ratio:

Contribution Margin Ratio = (Contribution Margin / Sales) * 100

To calculate the contribution margin, we need to subtract variable costs from sales:

Contribution Margin = Sales - Variable Costs = $1,100,000 - $645,000 = $455,000

Using the values, we can calculate the contribution margin ratio:

Contribution Margin Ratio = ($455,000 / $1,100,000) * 100 = 41.36%

Therefore, the contribution margin ratio is approximately 41.36%.

d. Operating Income:

Operating Income = Sales - Variable Costs - Fixed Costs

Using the values provided:

Operating Income = $1,100,000 - $645,000 - $282,500 = $172,500

Therefore, the operating income is $172,500.

h(8) = -15

f(3) = -(3)² + 8(3) - 11

f(3) = -9 + 24 - 11

f(3) = 4

h(8) - 2 f(3) = -15 - 2(4) = -23

The value of the h(8) is -15, the value of f(3) 4 after plugging the values of x in the function and the value of h(8) - 2 f(3) is -23.

It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.

It is given that:

Functions f(x) = -x²+8x-11 and

h(x)=-x-7

h(-8) = -8 - 7

h(-8) = -15

f(3) = -(3)² + 8(3) - 11

f(3) = -9 + 24 - 11

f(3) = 4

= h(8) - 2 f(3)

= -15 - 2(4)

= -23

From the information given,

w1 = 5(cos(15) + isin(15))

w2 = 3(cos(45) + isin(45))

Let A represent 15 degrees and B represent 45 degrees

To find w1 * w2, we would multiply each term in the first parentheses by each term in the second parentheses. We have

w1 * w2 = 5(Cos(A) + iSin(A)) * 3(Cos(B) + iSin(B))]

= 15[CosACosB + CosA * iSinB + iSinACosB + i^2SinASinB]

= 15[CosACosB + i(CosASinB + SinACosB) + i^2SinASinB]

= 15[CosACosB + i(SinACosB + CosASinB) + i^2SinASinB]

Recall, i^2 = - 1

Thus, we have

15[CosACosB + i(CosASinB + SinACosB) - SinASinB]

15[CosACosB - SinASinB + i(SinACosB + CosASinB)]

Recall the following trigonometric identities

Cos(A + B) = CosACosB - SinASinB

Sin(A + B) = SinACosB + CosASinB

By applying these identities, we have

15[Cos(A + B) + i(Sin(A + B)]

By replacing A with 15 and B with 45, we have

15[Cos(15 + 45) + i(Sin(15 + 45)]

= 15[(Cos60 + iSin60]

Option 1 is correct
