Step-by-step explanation:

Therefore, the standard deviation for the number of people with the genetic mutation in groups of 500 is approximately 6.726.

To find the standard deviation for the number of people with the genetic mutation in groups of 500, we can use the binomial distribution formula.

Given:

Probability of having the genetic mutation (p) = 0.09

Sample size (n) = 500

The standard deviation (σ) of a binomial distribution is calculated using the formula:

σ = √(n * p * (1 - p))

Substituting the given values:

σ = √(500 * 0.09 * (1 - 0.09))

Calculating the standard deviation:

σ ≈ 6.726 (rounded to three decimal places)

On a certain portion of an experiment, a statistical test result yielded a p-value of 0.18. From here we can conclude that test statistic at least as extreme as that observed 21% of the time, so the test is not statistically significant.

a field of mathematics concerned with the gathering, examination, interpretation, and presentation of large amounts of numerical data.: a set of numerical data

Statistics is the study and manipulation of data, including methods for data collection, evaluation, analysis, and interpretation. Descriptive statistics and inferential statistics are the two main subfields of statistics.

In the exercise, we obtain a value of p of 0.21; we assume that for it to have statistical significance, the value must be less than 0.05, which is constant; if this result is higher, it indicates that there is no statistically significant evidence. The test of the statistical p helps us determine the probability that a statistical value occurs in the null hypothesis.

The variance of the number of packages that will be filled before the process is stopped will be 600 when the probability of falling outside the specification is 0.04.

Variability is measured by the variance. The average of the squared deviations from the mean is used to calculate it. The degree of spread in your data set is indicated by variance. The variance is greater in relation to the mean the more dispersed the data. In statistics, the variance is used to assess how accurately the mean summarizes all of the data. For instance, more range exists within the set the higher the variance. 

P(fail)=0.04

P(pass)=0.96

variance=(1-P)/P²

=(1-0.04)/0.0016

=0.96/0.0016

Step-by-step explanation:

x+5+x+7x-5=180 degree (being the interior angles of a triangle)

9x=180

x=180/9

x=20 degree

Answer:

x° = 20°

Step-by-step explanation:

Sum of angles of triangles = 180°

Therefore,

(x + 5) + (7x - 5) + x = 180

x + 5 + 7x - 5 + x = 180

9x = 180

x = 20

∠M = (x + 5) = 20 + 5 = 25°

Therefore, Cassidy's upfront cost was $11.50.

Answer:

To find Cassidy's upfront cost, we need to use the information given in the problem and the formula for the linear function that models his profit:

Cassidy purchased a total of 150 containers of popcorn to sell.

After selling 25 containers, he will make a total profit, after his upfront costs, of $5.50.

Cassidy's profit after upfront costs can be modeled by a linear function in the form y = mx + b.

We know that when Cassidy sells 25 containers of popcorn, his profit after upfront costs is $5.50. Using the linear function, we can plug in 25 for x and solve for b, which represents the upfront costs:

y = mx + b

$5.50 = m(25) + b

$5.50 = 0.68(25) + b

$5.50 = $17.00 + b

b = $5.50 - $17.00

b = -$11.50

Therefore, Cassidy's upfront cost was $11.50.

Step-by-step explanation:

1. Cassidy is selling popcorn for a fundraiser sale at the following prices: $1

per container for the first 25 containers, $0.75 per container for the next 50

containers, and $0.50 per container for the remaining containers.

2. Cassidy purchased a total of 150 containers of popcorn to sell.

3. After selling 25 containers, Cassidy will make a total profit, after upfront

costs, of $5.50.

4. Cassidy's profit can be modeled by a linear function in the form of y=mx+b.

Answer:

C. The function will be continuous because Cassidy's profit will change

smoothly as he sells more containers of popcorn.

DD. To write the function that models Cassidy's profit, we need to find the slope

(m) and y-intercept (b) values.

Slope (m) = (profit for 50 containers-profit for 25 containers) / (50-25) =

($22.50 - $5.50) / 25 = $0.68

y-intercept (b) = $5.50

Therefore, the function that models Cassidy's profit is y = 0.68x + 5.50, where x

represents the number of containers of popcorn sold after the first 25.

E. The domain of the function is the set of non-negative integers from 0 to 125,

because Cassidy can sell anywhere from 0 to 125 containers of popcorn after

the first 25.

F. Cassidy's loss if he does not sell any popcorn is $-5.50, which means he lost

money due to the upfront costs.

G. Cassidy's profit if he sells all the popcorn is $82.00, which is the profit for

selling 125 containers of popcorn after the first 25.

H. The range of the function is the set of non-negative real numbers, because

Cassidy's profit can be any non-negative amount of money.

Formula used:

Slope (m) = (profit for 50 containers-profit for 25 containers) / (50-25)

• y-intercept (b) = $5.50

• Function: y = 0.68x + 5.50 (where x represents the number of containers of

popcorn sold after the first 25)

The measure of arc BC is 720 times the measure of angle BAC.

Given that AC is the diameter of the circle and AB is a chord with a length of 16 units, we need to find BC (the length of the other chord) and mBC (the measure of angle BAC).

To find BC, we can use the property of chords in a circle. If two chords intersect within a circle, the products of their segments are equal. In this case, since AB = BC = 16 units, the product of their segments will be:

AB * BC = AC * CE

16 * BC = 2 * r * CE (AC is the diameter, so its length is twice the radius)

Since the area of the circle is given as 289 square units, we can find the radius (r) using the formula for the area of a circle:

Area = π * r^2

289 = π * r^2

r^2 = 289 / π

r = √(289 / π)

Now, we can substitute the known values into the equation for the product of the segments:

16 * BC = 2 * √(289 / π) * CEBC = (√(289 / π) * CE) / 8

To find mBC, we can use the properties of angles in a circle. The angle subtended by an arc at the center of a circle is double the angle subtended by the same arc at any point on the circumference. Since AC is a diameter, angle BAC is a right angle. Therefore, mBC will be half the measure of the arc BC.

mBC = 0.5 * m(arc BC)

To find the measure of the arc BC, we need to find its length. The length of an arc is determined by the ratio of the arc angle to the total angle of the circle (360 degrees). Since mBC is half the arc angle, we can write:

arc BC = (mBC / 0.5) * 360

arc BC = 720 * mBC

Therefore, the length of the arc BC equals 720 times the length of the angle BAC.

It will take the town 21 years 4 months to reach 4600 in population

a rate is a ratio that compares two different quantities which have different units. For example, if we say John types 50 words in a minute, then his rate of typing is 50 words per minute. The word "per" gives a clue that we are dealing with a rate.

initial population = 3000

population increase every year = 2.5% of 3000

which is 2.5/100 x 3000 = 75

let the time taken to reach 4600 be d

increment for d number of years = 75d

Total population after d years is 75d + 3000

so 75d + 3000 = 4600

75d = 4600  - 3000

75d = 1600

d = 1600/75

d = 21.33 years which is 21 years 4 months

The slope of AB is different from the slope of BC

==================================================

Reason:

Points A,B,C are all on the same line. We consider them collinear points. This means that the slopes of AB, AC and BC are the same value.

If the slopes were different at all, then the points wouldn't be collinear. In this case, the slope is 2/3 because we move up 2 each time we move to the right 3 units.
