What is a Binomial Distribution?

The binomial distribution is a type of probability distribution that predicts the likelihood of obtaining one of two outcomes given a set of inputs. It summarizes the number of tries where each trial has the equal chance of producing the same result.

The formula for Binomial Distribution is given by

P ( x ) = [ n! / ( n - x )! x! ] pˣqⁿ⁻ˣ  

where

n = number of trials

x = number of successes

p = probability of getting a success in one trial

q = probability of getting a failure in one trial

q = 1 - p

Given data ,

Let the probability that you will have to deal with no more than 4 incidents be P ( x ≤ 4 )

Now , the success is one of your customers once every 9 weeks

So , p = 1/9

q = 1 - p = 8/9

x = 4

Number of trials n = 52 weeks

And , the probability that you will have to deal with no more than 4 incidents be P ( x ≤ 4 ) is

P ( x ≤ 4 ) = [ n! / ( n - x )! x! ] pˣqⁿ⁻ˣ  

Substituting the values in the equation , we get

P ( x ≤ 4 ) = [ 52! / ( 48 )! 4! ] ( 1/9 )⁴( 8/9 )⁴⁸

On simplifying the equation , we get

P ( x ≤ 4 ) = 0.3008

P ( x ≤ 4 ) = 30.08 %

Therefore , the value of P ( x ≤ 4 ) is 30.08 %

Hence , the probability of no more than 4 incidents is 30.08 %

Which function is shown in the graph below? On a coordinate plane, a function is shown. The curve starts in quadrant 4 and curves up to quadrant 1. It goes through (0.5, negative 0.4), (1, 0), and (6, 1). y = log Subscript one-sixth Baseline x y = log Subscript 0.5 Baseline x y = log Subscript 1 Baseline x y = log Subscript 6 Baseline x

Answers

Answer:

c

Step-by-step explanation:

The y-values of the graph increases as the value of x increases, which

indicates that a characteristic of the base of the logarithm function.

Correct response:

The function that corresponds with the graph is; [tex]\underline{\mathrm{y = log_6 x}}[/tex]

How can the function of a log graph be determined?

The given points on the graph are;

The point where the graph starts = Quadrant 4

Direction of the graph = From quadrant 4 to quadrant 1

Points on the graph are;

(0.5, -0.4), (1, 0), and (6, 1)

The given options are;

[tex]y = \mathrm{log_{\frac{1}{6} } x}[/tex]

[tex]y = \mathrm{log_{0.5} x}[/tex]

[tex]y = \mathrm{log_1 x}[/tex]

[tex]y = \mathrm{log_{6} x}[/tex]

From the shape of the graph, in which, log x increases as x increases, therefore;

The base, b, of the logarithm is larger than 1, given that we have;

[tex]\mathbf{log_bx} = y[/tex]

[tex]\mathbf{b^y} = x[/tex]

From the given coordinate points, x increases as y increases, therefore;

b > 1

The possibly option is therefore, y = log₆x

Verifying, we have;

At x = -0.4, y = 0.5

[tex]b^y = x[/tex]

[tex]6 ^{(-0.4)}[/tex] ≈ 0.488

Therefore, the point (0.5, -0.4) is close to the graph of y = log₆x

At the point (1, 0), we have;

6⁰ = 1

Therefore, the point (1, 0), is on the graph of y = log₆x

At the point (6, 1), we have;

6¹ = 6

Therefore, the point (6, 1) is on the graph of y = log₆x

The function of the graph is therefore;

[tex]\underline{ \mathrm{y = log_6 x}}[/tex]

Average point per game = 18 points

Number of games played = 16

Total points claimed = number of games played * average points per game

Total points = 18 * 16 = 288 points on average

Print rate = 12 pages per minute

Copying rate = 10 pages per minute

To print a 24 page research paper :

Time taken = number of pages / printing rate

Time taken = 24 / 12 = 2 minutes

Answers

Answer:

D. 8

Step-by-step explanation:

y varies jointly as x and z

y = k(xz)

-------------------------

Find k, the constant of variation

y = 12 when x = -2 and z=3

12 = k(-2 * 3)

12 = k(-6)

k = -2

-------------------------

find y when x is 4 and z is -1

using k = -2

y = -2(4 * -1)

y = -2(-4)

y = 8

What are the center and radius of the circle defined by the equation

O A. Center (3,-5); radius 9
B. Center (-3, 5); radius 3
C. Center (3,-5); radius 3
D. Center (-3, 5); radius 9

Answers

Answer: Center (3,-5); radius 3

Step-by-step explanation:

The center and radius of the circle defined by the equation is (3, -5) and 3.

What is Equation of Circle?

The standard equation of a circle is given by:

(x-h)² + (y-k)² = r²

Where (h,k) is the coordinates of center of the circle and r is the radius.

We have Equation,

x² + y² -6x + 10y +25= 0

Now, rearranging the terms

x² -6x + y² +10y +25 = 0

Now, add and subtract 9

x² -6x + 9 + y² +10y +25  -9 = 0

(x-3)² + (y+5)² = 3²

(x- 3)² + y(-(-5))² = 3²

So, the Centre of Circle is (3, -5) and the radius is 3.

Step-by-step explanation:

Can a person train to become better at holding their breath? An experiment was designed to find out. A group of 12 volunteers were randomly assigned to 1 of 2 groups. The 6 volunteers assigned to group 1 were given breath-holding exercises to perform for 2 weeks. The other group was not given any information about the experiment. At the end of the 2 weeks, all 12 volunteers were individually tested to determine how long they could hold their breath. Here are the data (in seconds):

Group 1: 90, 88, 70, 110, 75, 105

Group 2: 40, 48, 35, 50, 55, 62

The researcher would like to determine if these data provide convincing evidence that the true mean amount of time volunteers who were given training held their breath is greater than the true mean amount of time volunteers without training held their breath. The researcher tests H0: μ1 – μ2 = 0, Ha: μ1 – μ2 > 0, where μ1 = the true mean amount of time that volunteers who were given training held their breath and μ2 = the true mean amount of time that volunteers without training held their breath. The conditions for inference are met. The standardized test statistic is t = 5.44. What is the P-value of this test closest to?

Answer is A, 0

Answers

The null hypothesis may be significantly rejected. Choose A, 0, for the closest response.

What does "true mean" refer to?

In statistics, the term "true mean" refers to the true mean of a population or set of data.

It is typically unknown; hence it is estimated using inferential statistics using a sample.

For group 1, s1²= 250.67

group 2, s2² = 96.27

t= 5.44 which is the difference of mean.

Given the data values:

Group 1: 90 88 70 110 75 105

Group 2: 40 48 35 50 55 62

For group 1, n1 = 6

group 2, n2 = 6

Given that H_o= u1 - u2 = 0

H_a = u1 - u2 > 0

To find the t-test about the difference, we would use the formula to solve.

The totals are displayed below:

x1 = 538

x2 = 290

(x1-x2) ² = 1253.3334

x2-x2= 0

(X2-x2) ² =481.3334

For group 1, s1²= 250.67

group 2, s2² = 96.27

t= 5.44 which is the difference of mean.
