5(3-x)-4(2-3x)>2 what is the inequality of x

Plair wants to save $100. so far she has saved $ 63. how much more does plair need to save ?

Novay_Z [31]

Hello!

To find out how much more she needs to save, simply subtract 63 from 100:

100-63=37.

I hope it helps!

Did I graph this linear equation correctly?

devlian [24]

Answer:

Step-by-step explanation:

The question asks you to graph the inequality

<em>The steps of drawing the inequality are the same steps of drawing the equation except the area of the solution</em>

→ The solution of the equation is just all the points lie on the line

→ The solution of the inequality is one of these cases:

All the points on the line and on the area down the line if the inequality y ≤ ......

All the points on the line and on the area over the line if the inequality y ≥ .......

All the points on the area down the line if the inequality y < ......

All the points on the area over the line if the inequality y > .......

∵ The inequality is 4x - 3y ≤ 6

∴ The equation of the line is 4x - 3y = 6

Your drawing is right, BUT you must shade the area over the line because the solution of the inequality is all the points on the line and over the line

The coefficient of y is -3 which means we will divide the sides of the inequality by a negative number, so sign the inequality must e reversed

I attached the figure of the inequality to show you the explanation above.

The red shaded is the area of the solution of the inequality.

Smallest number to the largest number 0.078,0.78,0.87,0.708

PilotLPTM [1.2K]

0.078, 0.708, 0.78, 0.87.

The further down the number is after the decimal point , the smaller it is; for example, 0.005 is smaller than 0.05. Hope that helped.

What is meant by the term "90% confident" when constructing a confidence interval for a mean? Group of answer choices

Harman [31]

Answer:

The question is not complete, below is the complete question:

What is meant by the term 90% confident? when constructing a confidence interval for a mean?

a. If we took repeated samples, approximately 90% of the samples would produce the same confidence interval.

b. If we took repeated samples, approximately 90% of the confidence intervals calculated from those samples would contain the sample mean.

c. If we took repeated samples, approximately 90% of the confidence intervals calculated from those samples would contain the true value of the population mean.

d. If we took repeated samples, the sample mean would equal the population mean in approximately 90% of the samples.

Answer:

The correct answer is:

If we took repeated samples, approximately 90% of the confidence intervals calculated from those samples would contain the true value of the population mean. (c)

Step-by-step explanation:

a 90% confidence level means that if repeated samples were taken, 9 out of 10 times, the confidence intervals of the sample chosen will be close to the mean (true value), which is a true representation of the population parameter. when using confidence intervals, there are always margins of allowable accuracy, and this is suggested by using standard diviations snd variances.

I attached a simple document to this answer that will give you more insight into confidence intervals used in statistics.
