Step-by-step explanation:

There is a 5/6 probability that you will remove pairs of socks to make sure you obtain a pair that is not navy.

Simply put, the probability is the likelihood that something will occur. When we don't know how an event will turn out, we can discuss the likelihood or likelihood of several outcomes.

Statistics is the study of events that follow a probability distribution.

So, we know that:

27 black socks.

18 grey socks.

9 navy socks.

Probability formula: P(E) = Favouravle events/Total events

Now, insert values in the formula as follows:

P(E) = Favouravle events/Total events

P(E) = 27+18/27+18+9

P(E) = 45/54

P(E) = 15/18

P(E) = 5/6

Therefore, there is a 5/6 probability that you will remove pairs of socks to make sure you obtain a pair that is not navy.

Step-by-step explanation:

The surface area of a cylinder can be found by adding the area of the top and bottom circles to the lateral area (the curved surface). The exact surface area of the cylinder is 10 pi square units.

The area of each circle is pi times the radius squared, so:

Area of top circle = pi * (5/4)^2 = 25/16 * pi

Area of bottom circle = pi * (5/4)^2 = 25/16 * pi

The lateral area is the height times the circumference of the circle, so:

Lateral area = height * circumference = (11/4) * (2 * pi * (5/4)) = 55/8 * pi

Adding these three areas together, we get:

Surface area = 2 * (25/16 * pi) + 55/8 * pi

Surface area = 50/16 * pi + 55/8 * pi

Surface area = 25/8 * pi + 55/8 * pi

Surface area = 80/8 * pi

Surface area = 10 * pi

Therefore, the exact surface area of the cylinder is 10 pi square units. None of the answer options provided matches this exact result, but the closest one is 19 3/8 pi cm sq.

Answer:

C; 8x+3y= 45  

Step-by-step explanation:

The process is really long so here we go...

8x+3y=15 is the equation and we want to bring it to slope intercept form so that we can know what the slope is.

(8x+3y=15) -8x = (3y=-8x+15) /3 = y= -8/3x +5

We now know that the slope of the equation is -8/3x, and since we are trying to find out a line parallel to the that equation we can use the same slope in the equation: y+y1=m(x+x1)

Which would be: y-1=-8/3(x+6)

then: y-1=-8/3x-16

then: y= 8/3x+15

We're not done yet because we have to simplify it to standard form so we can subtract 8/3x so that it can join the y's side, and we would have the multiply the whole equation by -3 so that x wouldn't be a fraction, which results it not being in standard form. That leaves the final answer, 8x+3y=45

The equation in standard form of the line that passes through the point (6, -1) and is parallel to the line represented by  8x + 3y = 15 is 8x + 3y = 45

Ax + Bx = C

where

Therefore, using slope intercept form

y = mx + b

where

m = slope

b = y-intercept

8x + 3y = 15

3y = -8x + 15

y = -8 / 3 x + 5

slope = - 8 / 3

It passes through (6, -1)

let's find b

-1 = - 8 / 3 (6) + b

-1 = -48 / 3 + b

-1  = -16 + b

b = -1 + 16

b = 15

Therefore,

y = - 8 / 3 x + 15

8 / 3 x  + y = 15

8x + 3y = 45

If the width is 5 inches, then the volume of the box is 330 inches³.

Based on the problem, the width of the box is 5 inches, then we can substitute that value into the equation for width:

x - 1 = 5

Solving for x, we get:

x = 5 + 1 = 6

Now that we know the value of x, we can substitute it into the equations for length and height:

length = 2x - 1 = 2(6) - 1 = 11 inches

height = x = 6 inches

Use these measurements to calculate the volume of the box. The volume of a rectangular box is found by multiplying the length, width and height:

volume = length x width x height

volume = 11 x 5 x 6 = 330 inches³

Therefore, the volume of the box is 330 cubic inches.

Loop3 (O(\(log_2\)(n))) has the fastest running time.

Let's analyze the three loops and determine their time complexities.

Loop1:

while n > 50

   n ← π/\(b^2\)

endwhile

m ← -10n

In this loop, the value of n is updated in each iteration as n ← π/\(b^2\), where b is a constant. The loop continues until n becomes less than or equal to 50. The value of n decreases with each iteration, converging towards 50. Since the value of n is divided by \(b^2\) in each iteration, the number of iterations required for n to reach 50 can be approximated as \(log_b\)(n/50). Therefore, the time complexity of this loop can be expressed as:

Time complexity of Loop1: O(\(log_b\)(n/50))

Loop2:

while n > m

   n ← n - b

endwhile

m ← 2n

In this loop, the value of n is decremented by b in each iteration until it becomes less than or equal to m. Then m is updated to 2n. The number of iterations required for n to reach m can be approximated as n/b. Therefore, the time complexity of this loop can be expressed as:

Time complexity of Loop2: O(n/b)

Loop3:

while n > 2

   n ← √n

endwhile

In this loop, the value of n is updated in each iteration as n ← √n. The loop continues until n becomes less than or equal to 2. The value of n decreases with each iteration, converging towards 2. The number of iterations required for n to reach 2 can be approximated as \(log_2\)(n). Therefore, the time complexity of this loop can be expressed as:

Time complexity of Loop3: O(\(log_2\)(n))

To answer the question regarding Ω(\(log_2\)(n)), O(\(log_2\)(n)), or Θ(\(log_2\)(n)), it seems that the third loop, Loop3, has a time complexity of O(\(log_2\)(n)). The other two loops, Loop1 and Loop2, have different time complexities.

Finally, when b = 2, we can compare the time complexities of the loops:

Loop1: O(\(log_2\)(n/50))

Loop2: O(n/2)

Loop3: O(\(log_2\)(n))

Comparing these time complexities, we can observe that Loop3 (O(\(log_2\)(n))) has the fastest running time, as the time complexity is independent of n. Loop1 (O(\(log_2\)(n/50))) depends on the value of n, and Loop2 (O(n/2)) has a linear time complexity with respect to n.

To determine the interest rate Bank B must pay, we equate the future values of both accounts after 10 years and solve for Bank B's interest rate.

To find the interest rate Bank B must pay for Derek to have the same amount in both accounts after 10 years, we can calculate the future value of each account and equate them. For Bank A, using the formula for monthly compound interest:

Future Value = Principal * (1 + (interest rate/12))^n, where n is the number of months

Principal = $240.00, interest rate = 14.00% per annum

Future Value of Bank A = $240.00 * (1 + (0.14/12))^(10*12)

For Bank B, using the formula for annual compound interest:

Future Value = Principal * (1 + interest rate)^n, where n is the number of years

Principal = $2,467.00, interest rate = unknown

Future Value of Bank B = $2,467.00 * (1 + interest rate)^10

Equating the future values and solving for the interest rate of Bank B gives the required rate.Therefore, To determine the interest rate Bank B must pay, we equate the future values of both accounts after 10 years and solve for Bank B's interest rate.

The three values (60, 62, and 84) are identified as outliers for the age group 40 years to 50 years is D. Only 60 and 84 are identified as outliers

we need to use the same method as for the age group 20 years to 30 years.

The interquartile range (IQR) for the age group 40 years to 50 years is calculated as follows:

Q3 - Q1 = 76 - 70 = 6

To identify outliers, we consider values that are either 1.5 times the IQR greater than the upper quartile (Q3 + 1.5 * IQR) or 1.5 times the IQR less than the lower quartile (Q1 - 1.5 * IQR).

For the age group 40 years to 50 years:

Upper limit = Q3 + 1.5 * IQR = 76 + 1.5 * 6 = 85

Lower limit = Q1 - 1.5 * IQR = 70 - 1.5 * 6 = 61

Now let's compare these limits with the three values:

60 is less than the lower limit (61), so it is considered an outlier.

62 is between the lower and upper limits, so it is not considered an outlier.

84 is greater than the upper limit (85), so it is considered an outlier.

Therefore, the values identified as outliers for the age group 40 years to 50 years are 60 and 84. The value 62 is not considered an outlier.

The correct answer is (D) Only 60 and 84 are identified as outliers.

By applying the same method of identifying outliers based on the 1.5 times IQR rule, we can determine which values fall outside the acceptable range for each age group. Therefore, Option D is correct

The volume of composite figure is 1,079.66 in³.

The volume  and surface area of the composite figure is calculated by applying the following formula as shown below;

The surface area = area of cone + area of hemisphere

S.A = πr(r + l) + 3πr²

S.A = π x 10 (10 + 13)  +  3π(10²)

S.A = 1,665.04 in²

The volume of composite figure is calculated as follows;

V = ¹/₃πr²h  +  ²/₃πr²

For the probability distribution of a discrete random variable x, the sum of all values of x must be equal to 1.

We have,

The sum of all values of a discrete random variable x in its probability distribution should be equal to 1 because the probability distribution represents the likelihood of each possible value occurring.

In other words, the probabilities assigned to each value of x should account for all possible outcomes and collectively add up to the total probability of 1, which represents the certainty or 100% likelihood of an event occurring.

In a probability distribution, each value of x has an associated probability assigned to it.

These probabilities must satisfy two conditions: they must be non-negative (greater than or equal to 0) and their sum must be equal to 1. This ensures that the total probability accounts for all possible outcomes and covers the entire sample space.

By summing up the probabilities for all values of x in the probability distribution, we can verify if they add up to 1. If the sum is not equal to 1, it implies that there is an error in the probability distribution, and it needs to be adjusted to meet the requirement of a valid probability distribution.

Thus,

For the probability distribution of a discrete random variable x, the sum of all values of x must be equal to 1.
