Chance is a term used to represent the percentage of time a specific result is expected to occur when the same basic procedure is repeated over and over again, where each repetition is independent.

Chance is a term that is used to describe the probability that a certain outcome will occur given a set of fundamental instructions repeated again with each repetition being independent.

Ultimately, this means the number of times a result of an event occurs when repeated over a number of times is chance.

Answer:

13mm

Step-by-step explanation:

To calculate the mean length of the insects Mick found, we need to find the sum of all the lengths multiplied by their respective frequencies, and then divide it by the total frequency.

The length intervals and their frequencies are as follows:

0 < x ≤ 10 (frequency = 9)

10 < x ≤ 20 (frequency = 6)

20 < x < 30 (frequency = 5)

To calculate the mean length, we can follow these steps:

Multiply each length interval by its corresponding frequency:

Sum = (9 * (0 + 10)/2) + (6 * (10 + 20)/2) + (5 * (20 + 30)/2)

= (9 * 5) + (6 * 15) + (5 * 25)

= 45 + 90 + 125

= 260

Calculate the total frequency by adding up the frequencies:

Total frequency = 9 + 6 + 5

= 20

Divide the sum by the total frequency to find the mean length:

Mean length = Sum / Total frequency

= 260 / 20

= 13

Therefore, the estimate of the mean length of the insects Mick found is 13 mm.

since we the the value of a straight line is 180° we can make an equation

Answer: The total number of members in the club is 140 + 695 + 210 = 1,045.

The number of non-senior members is 140 + 695 = 835.

The probability that the first member selected at random will not be a senior member is 835 / 1,045 = 0.798 or 79.8%.

So, the answer is 0.798 or 79.8%.

The sequence given is known as the Collatz sequence or the Hailstone sequence.

According to the given sequence,

if a value is even, divide it by 2 and if it is odd, multiply it by 3 and add 1.

This process of operation must continue until the number 1 is reached.

Suppose the first number in the sequence is x, and then we can define the sequence as a 0 = x;an+1 = an / 2,

if an is even; an+1 = 3 X an + 1, if an is odd.

The sequence will continue in this manner until we reach the value of ak = 1.

To determine the equation of the tangent plane and normal line of the given curve at the point P(2, -3, 18), we need to find the partial derivatives of the function f(x, y, z) = x^2 + y^2 - 2xy - x + 3y - z - 4.

Taking the partial derivatives with respect to x, y, and z, we have:

fx = 2x - 2y - 1

fy = -2x + 2y + 3

fz = -1

Evaluating these partial derivatives at the point P(2, -3, 18), we find:

fx(2, -3, 18) = 2(2) - 2(-3) - 1 = 9

fy(2, -3, 18) = -2(2) + 2(-3) + 3 = -7

fz(2, -3, 18) = -1

The equation of the tangent plane at P is given by:

9(x - 2) - 7(y + 3) - 1(z - 18) = 0

Simplifying the equation, we get:

9x - 7y - z - 3 = 0

To find the equation of the normal line, we use the direction ratios from the coefficients of x, y, and z in the tangent plane equation. The direction ratios are (9, -7, -1).Therefore, the equation of the normal line passing through P(2, -3, 18) is:

x = 2 + 9t

y = -3 - 7t

z = 18 - t

where t is a parameter representing the distance along the normal line from the point P.

Considering the probability space whose outcomes are these random permutations and a random variable X defined on this probability space such X = 1 when the product xyz is even and X = 0 when that product is odd. E[X] = \[\frac{53}{63}\]

To find the expected value of the random variable X given the permutation of 10 decimal digits, we will determine the probability of the random variable X being odd or even. If the product xyz is odd, then X is odd, otherwise X is even.

Let A be the event that x is odd, B be the event that y is odd and C be the event that z is odd. The probability of A occurring is:

P(A) = \[\frac{5}{9}\] since there are 5 odd digits out of the 9 remaining after any digit is chosen as the first digit in x. Similarly, P(B) = \[\frac{4}{7}\] since there are 4 odd digits out of the 7 remaining after any digit is chosen as the first digit in y. Also, P(C) = \[\frac{3}{6}\] since there are 3 odd digits out of the 6 remaining after any digit is chosen as the first digit in z.

Therefore, P(A ∩ B ∩ C) is the probability of the product being odd which is given as:

P(A ∩ B ∩ C) = P(A) × P(B) × P(C) = \[\frac{5}{9}\] × \[\frac{4}{7}\] × \[\frac{3}{6}\] = \[\frac{10}{63}\]

Thus, the probability of the product being even is:

P(A ∩ B ∩ C)¯ = 1 − P(A ∩ B ∩ C) = 1 − \[\frac{10}{63}\] = \[\frac{53}{63}\]

Therefore, the expected value of X is given as:

E[X] = (0 × \[\frac{10}{63}\]) + (1 × \[\frac{53}{63}\]) = \[\frac{53}{63}\]

The probability that the next chew Harper removes from the bag will be a lime chew is 26%.

We know that there are a total of 38 chews in the bag, and that 10 of them are lime chews. This means that the probability of randomly selecting a lime chew is 10/38 = 0.2631578947. To the nearest whole number, this is 26%.

It is important to note that this is just a probability. It is possible that the next chew Harper removes from the bag will not be a lime chew. However, based on the results of the experiment, the probability is 26% that it will be.

Here are some additional details about the probability of randomly selecting a lime chew from the bag:

The probability of randomly selecting a lime chew is not guaranteed to be 26%. If Harper performs the experiment more times, the probability may change.

The probability of randomly selecting a lime chew is also affected by the number of lime chews in the bag. If Harper removes more lime chews from the bag, the probability of randomly selecting a lime chew will decrease.

The probability of randomly selecting a lime chew is also affected by the way that Harper removes the chews from the bag. If Harper does not return the chews to the bag after each selection, the probability of randomly selecting a lime chew will increase.

According to the equation of the trend line the population will reach 52900 in 27831 years.

A mathematical statement known as an equation is a combination of two expressions joined together by the equal sign.

The equation of the trend line is:

y = 1.9x + 21

where, y is the population and x indicate the year.

To find the number of years in which the population reach 52900, substitute y = 52900.

y = 1.9x + 21

52900 = 1.9x + 21

52900 - 21 = 1.9x

52879/ 1.9 = x

x = 27831

Hence, according to the equation of the trend line the population will reach 52900 in 27831 years.
