A parachutist has made thousands of successful jumps. His assumption is that when he pulls the rip cord, that parachute will open.

What are the null and alternative hypothesis?

Describe a Type I error along with the consequence.

Describe a Type II error along with the consequence.

What is a more serious error in this context? Justify your answer.

Most parachutes have a backup in case the ripcord malfunctions. Does the guard against Type I or Type II errors? Explain.

Suppose you went skydiving and pull the ripcord and it does not function. You have time to pull it again or pull the back up but not both. What would you do?

Answers

The null hypothesis is the one in which any statement which is the claim of the experiment is chosen to decide the results for .

The alternate hypothesis is the opposite of the null hypothesis.

Type I Error:  Type I Error occurs when H0 is true but it is rejected and Ha is accepted.

Type II Error:  Type II Error occurs when Ha is true but it is rejected and the false null hypothesis H0 is accepted which is wrong decision.

In this case the null hypothesis is

H0: On pulling the rip cord the parachute will open.

Ha: On pulling the rip cord the parachute will not open.

In this experiment the alternate hypothesis Ha :On pulling the rip cord the parachute will not open is accepted then type I error occurs.

In this experiment the null hypothesis H0 :On pulling the rip cord the parachute will not open is accepted then type II error occurs.

In this experiment Type I Error is a more serious error because the true null hypothesis H0: the parachute will open is rejected.

In this experiment Type II Error is a more serious error.

Type I and Type II Errors are independent of the confidence interval.

When the parachute has a backup in case of ripcord malfunctions then the confidence level of the hypothesis can be 100 percent. That is we are 100 percent sure that the parachute will land safely and there will be no accidents.

This is does not guard the type I and type II errors because these are made on the wrong decision.

The null and alternate hypotheses can be understood here

how to solve x^2+x-90=0 in completing the square method​

Answers

Rearrange the equation by writing

x² + x - 90 = 0

x² + x = 90

x² + x + 1/4 = 90 + 1/4

Recall that (a + b)² = a² + 2ab + b². Then

x² + 2 • x/2 + (1/2)² = 361/4

(x + 1/2)² = 361/4

x + 1/2 = ± √(361/4)

x = -1/2 ± 19/2

x = 9   or   x = -10

-Write a real-world situation that could be represented by the equation 12.5x + 30 = -7.5x + 90.5.

What does the variable represent?​

Answers

Answer:

Imagination

Step-by-step explanation:

12.5x + 30 = -7.5x + 90.5.

12.5x + 30 = -7.5x + 90.5.

20x =60.5

x = 3 1/5

The sales from a music event comes from x tickets sold, at $12.50 a ticket, plus a rental income fee of $30 for an advertising billboard behind the stage.

The cost of the performance includes a musician's fee of $7.50 per ticket sold, plus a $90.5 rental fee for the stage.

The equation will tell us the number of tickets, x, that must be sold to break even (Inclome on the left and expenses on the right).

We need to sell at least 3 1/5 tickets to break even.  It's going to be close.

The equation 12.5x + 30 = -7.5x + 90.5  used to determine the point in time (number of weeks) at which their combined savings and spending will equal the cost of the trip.

The equation 12.5x + 30 = -7.5x + 90.5 could represent their financial situation.

The variable "x" represents the number of weeks they have been saving money.

The term 12.5x represents the total amount of money Friend A has saved over "x" weeks at a rate of $12.5 per week.

The term -7.5x represents the total amount of money Friend B has spent over "x" weeks at a rate of $7.5 per week (which is subtracted since it's being spent).

The constants 30 and 90.5 represent initial savings and the total funds needed for the trip, respectively.

Step-by-step explanation:

apply formula for (4m^2)/(2m^-3)

=(4m^(2--3)/(2)

=4m^5/2

divide 4/2

=3n^2/ -m^3

both parts:

(2m^5* 3n^2)/ -m^3

= -(2m^5* 3n^2)/ m^3

= -(2m^(5-3)* 3n^2)/ 1

= -(2m^2* 3n^2)

The perimeter of a rectangle is 80 inches. The length of the rectangle is 12 inches.

Which equation could represent the width of the rectangle, w?

Answers

Answer:

That will be 7

Step-by-step explanation:

The equation that represents the width of the rectangle will be 2(L + W) = 80. And its width is 28 inches.

What is the perimeter of the rectangle?

Let W be the rectangle's width and L its length.

The perimeter of the rectangle will be defined as the total length of all of its sides. So the rectangle's perimeter will be

Perimeter of the rectangle = 2(L + W) units

The perimeter of a rectangle is 80 inches. The length of the rectangle is 12 inches. Then the equation is given as,

2(L + W) = 80

2(12 + W) = 80

12 + W = 40

W = 40 - 12

W = 28 inches

The equation that represents the width of the rectangle will be 2(L + W) = 80.
