The probability that a randomly selected Atlantic cod has a length of 53.68 cm or less is given by the equation P ( x > 38.68 ) = 0.99865

The relationship between a value and the mean of a set of values is expressed numerically by a Z-score. The Z-score is computed using the standard deviations from the mean. A Z-score of zero indicates that the data point's score and the mean score are identical.

The Z-score is calculated using the formula:

z = (x - μ)/σ

where z: standard score

x: observed value

μ: mean of the sample

σ: standard deviation of the sample

Given data ,

Let the probability that a randomly selected Atlantic cod has a length of 53.68 cm or less be represented as P

Now , the equation will be

The observed value of x = 38.68 cm

The mean of the sample μ = 49.9 cm

The standard deviation of the sample σ = 3.74 cm

Now , z-score is calculated using the formula:

z = (x - μ)/σ

Substituting the values in the equation , we get

z = ( 38.68 - 49.9 ) / 3.74

z = -3

Now ,the p value from the z table is

P ( x > 38.68 ) = 1 - P ( x < 38.68 )

P ( x < 38.68 ) = 0.0013499

P ( x > 38.68 ) = 0.99865

And , the probability is P ( x > 38.68 ) = 0.99865 = 99.865 %

Hence , the probability is 84.392 %

A statistic is an estimate or calculation based on a sample size of data, while a parameter is a numerical characteristic of an entire population.

A statistic is a value or set of values which are calculated from a sample of data. Statistic values are used to measure attributes of a population, such as the mean, median, or mode of a population. Statistic values are estimates and can be subject to sampling error. Parameters, on the other hand, are numerical characteristics of an entire population. Parameters are fixed values which describe the population as a whole. For example, thirty percent of all dog owners might be a statistic, as it is an estimate based on a sample of data. However, the total number of dog owners would be a parameter, as it describes the entire population of dog owners. Parameters are not subject to sampling error, and they cannot be calculated from a sample set of data.

Answer: a. The rate of change in this situation represents the average number of pages read per minute. From the table, it can be seen that the rate of change is constant, as the ratio of the change in y (pages) to the change in x (minutes) is always the same.

For example, when x increases from 0 to 5, y increases from 0 to 25, so the rate of change is 25/5 = 5 pages per minute.

b. To represent the total number of pages as it relates to the number of minutes read, a linear equation can be used. The slope of the line represents the rate of change, and the y-intercept represents the number of pages read when x is equal to 0 (minutes).

Using the rate of change from the above example (5 pages per minute), the equation can be written as y = 5x + 0, where x represents the number of minutes and y represents the total number of pages read.

a vertical line is just  X = ......

So for this one through the point  7,-7     just      x = 7

The slope-intercept form of the lines are given below.

In mathematics, a line's slope, also known as its gradient, is a numerical representation of the line's steepness and direction.

If a line passes through two points (x₁ ,y₁) and (x₂, y₂),

then the equation of line is

y - y₁ = (y₂- y₁) / (x₂ - x₁) x (x - x₁)

To find the slope;

m =  (y₂- y₁) / (x₂ - x₁)

Given:
A). Line 5 passes through (0, 5) and (10, 0),

then the equation of the line is,

y - 5 = -1/2(x)

B). Line 6 passes through (0, 7) and (1, 7),

then the equation of the line is,

y = 7

C). Line 7 passes through (0, 0) and (9, 3),

then the equation of the line is,

y = 3x

D). Line 8 passes through (-1, 0) and (0, 1),

then the equation of the line is,

y = x + 1

E). Line 9 passes through (-1, 1) and (0, -1),

then the equation of the line is,

y = -2x - 3

F). Line 10 passes through (0, 2) and (-0.5, 8),

then the equation of the line is,

y = -12x + 24

G). Line 11 passes through (4, 0) and (4, 1),

then the equation of the line is,

x = 4

Step-by-step explanation:

The measure of the smallest angle of the triangle would be = 33°

The total angle measurement of a triangle is a total of 180°.

That is ;

180° = 90 + (4x-7)° + (3x-15)°

180 = 90-7-15+4x+3x

180 = 90-22+7x

180 = 68+7x

180-68 = 7x

7x = 112

X= 112/7

X= 16

substitute X=16 into both angles (4x-7)° and (3x-15)° to know the smallest.

It took the 26 offshore oil workers an average of 94.85 seconds to complete the simulated escape exercise, with a variance of 828.19 and a standard deviation of 28.79 seconds.

The data set consists of 26 offshore oil workers who took part in a simulated escape exercise. The data set measures the time (in seconds) it took for each worker to complete the escape. To analyze the data, we can calculate the mean, variance, and standard deviation.

The mean is calculated by adding up the time for each worker and dividing the sum by the total number of workers (26). This results in a mean of 94.85 seconds.

The variance is calculated by subtracting the mean from each individual time, squaring the results, adding the squared results together, and dividing the sum by the total number of workers (26). This results in a variance of 828.19.

The standard deviation is calculated by taking the square root of the variance. This results in a standard deviation of 28.79 seconds.

In conclusion, it took the 26 offshore oil workers an average of 94.85 seconds to complete the simulated escape exercise, with a variance of 828.19 and a standard deviation of 28.79 seconds.

Given that, a group of retailers will buy 104 televisions from a wholesaler if the price is $350 and 144 if the price is $300.

Here, (104, 350) and (144, 300)

Now, slope (m)=(300-350)/(144-104)

= -50/40

= -1.25

Substitute m=-1.25 and (x, y)=(104, 350) in y=mx+c, we get

350=-1.25(104)+c

350=-130+c

c=480

Substitute m=-1.25 and c=480 in y=mx+c, we get

y= -1.25x+480

The wholesaler is willing to supply 68 if the price is $300 and 148 if the price is $390.

Thus, we can find the percentage of a number using the formula

[tex]Px=y[/tex], where P is the percentage.  In context of the question, x is how many megabytes have already downloaded and y is 281.

We simply need to solve for x and round to the nearest:

[tex]\frac{16.3}{100}x=281\\ \\0.163x=281\\x=1723.92638=1723.9[/tex]

Answer:

P = C(55,845, 40) / C(56,142, 40) = (55,845!) / (40! * (55,845 - 40)!) / (56,142!) / (40! * (56,142 - 40)!)

Step-by-step explanation:

To find the probability that none of the 40 subjects randomly selected left the treatment center against medical advice, we can use the formula for combinations. The number of ways to choose 40 subjects out of 55,845 that did not leave against medical advice is given by C(55,845, 40), which can be calculated as:

C(55,845, 40) = 55,845 choose 40 = (55,845!) / (40! * (55,845 - 40)!)

The probability that none of the 40 subjects randomly selected left the treatment center against medical advice is given by the number of ways to choose 40 subjects out of 55,845 that did not leave against medical advice, divided by the number of ways to choose 40 subjects out of 56,142 total subjects:

P = C(55,845, 40) / C(56,142, 40) = (55,845!) / (40! * (55,845 - 40)!) / (56,142!) / (40! * (56,142 - 40)!)

The measure of the angle m∠BDE obtained using the exterior angles theorem is 86°. The correct option is therefore;

86°

The exterior angle theorem states that the angle formed by two secants, a secant and a tangent or two tangents of a circle is equivalent to the half of the difference of the arcs intercepted.

The specified interior angle of the triangle ΔOBJ, ∠J = 47°

The segments OJ and BO are radial lengths of the circle, therefore;

JO ≅ BO

JO = BO (definition of congruency)

The triangle ΔOBJ is an isosceles triangle (definition of isosceles triangles)

∠J ≅ ∠B (Base angles of an isosceles triangle)

∠B = ∠J = 47°

m∠BOJ = 180°- 47° - 47° = 86° (angle sum property of a triangle)

Whereby EJ is a diameter of the circle, with center at O, we get;

∠BOJ and ∠BOE are linear pair angles, therefore;

m∠BOJ + m∠BOE = 180° (Linear pair angles are supplementary)

m∠BOE = 180° - m∠BOJ

m∠BOE = 180° - 86° = 94°

The exterior angle theorem indicates that we get;

m∠BDE = Half the difference of the intercepted arcs BJE and BE, found as follows;

[tex]m\widehat{BE}[/tex] = m∠BOE = 94°

[tex]m\widehat{BJE}[/tex] = 360° - m∠BOE = 360° - 94° = 266°

[tex]m\widehat{BJE}[/tex] = 266°

m∠BDE = ([tex]m\widehat{BJE}[/tex] - [tex]m\widehat{BE}[/tex])/2

To determine whether the consumer group's belief is supported by the sample data, we can perform a one-sample t-test.

The null hypothesis is that the true average score improvement is equal to 50 points, while the alternative hypothesis is that it is less than 50 points.

Using the sample data, we can calculate the t-statistic as:

t = (sample mean - hypothesized mean) / (sample standard deviation / sqrt(sample size))

t = (44 - 50) / (27 / √(31))

t = -1.24

The degrees of freedom for this test is 30 (sample size minus one).

Using a t-distribution table or calculator, we can find the p-value associated with this t-statistic and degrees of freedom, which is the probability of observing a t-statistic as extreme as -1.24 or more extreme, assuming that the null hypothesis is true.

The p-value is approximately 0.112.

Since the p-value is less than the significance level of 0.05, we reject the null hypothesis and conclude that there is evidence that the true average score improvement is less than 50 points.
