HELP ME ASAP PLEASE I'LL GIVE U BRAINIEST Recall your studies of geometry (or another math course) and algebra. Choose one that

you think is better. Define what you mean by better, and explain your choice. Better could mean, for example, more interesting, more challenging, more accessible, more abstract, or more tangible.

This is what I put in my response

For me I thought that algebra was better. I loved algebra I mean math is math somethings in math are hard, somethings are easy, sometimes in math you will come across something that seems impossible. Sometimes you will fly thru but, what makes the journey bearable is the people around you. Why I think algebra is better is because of the people that were in math course with me and my teacher because. The teachers make all the difference.

Im broke have this but like whats 24X58-9=<br><br><br><br> 800x24=?
Mekhanik [1.2K]

Answer:

24X58-9=1,383

800x24=19,200

Step-by-step explanation:

24x58=(24x8)+(24x50)

24x8=160+32=192

24x50=200+1,000=1,200

192+1,200=1,392-9=1,383

800x24=3,200+16,000=19,200

What is the slope of the line represents by 5x-12y=24 -2 24/5 -12 5/12 How do you get the answer? Please epxlain
mrs_skeptik [129]

5x - 12y = 24 - it's a standard form of equation of a line

The slope-intercept form: y = mx + b

m - slope

b - y-intercept.

Convert the standard form to the slope-intercept form:

5x - 12y = 24       <em>subtract 5x from both sides</em>

-12y=-5x+24      <em>divide both sides by (-12)</em>

y=\dfrac{5}{12}x-2

Answer: \boxed{\dfrac{5}{12}}

The speeds of vehicles traveling on a highway are normally distributed with an unkown population mean and standard deviation. A
Maksim231197 [3]

Answer:

The 90% confidence interval would be given by (60.09;69.91)    

We are 90% confident that the true mean for the speeds of vehicles traveling on a highway is between 60.09 and 69.91 miles per hour.

Step-by-step explanation:

1) Previous concepts

A confidence interval is "a range of values that’s likely to include a population value with a certain degree of confidence. It is often expressed a % whereby a population means lies between an upper and lower interval".

The margin of error is the range of values below and above the sample statistic in a confidence interval.

Normal distribution, is a "probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean".

\bar X =65 represent the sample mean for the sample  

\mu population mean (variable of interest)

s=9 represent the sample standard deviation

n=11 represent the sample size  

2) Confidence interval

The confidence interval for the mean is given by the following formula:

\bar X \pm t_{\alpha/2}\frac{s}{\sqrt{n}}   (1)

In order to calculate the critical value t_{\alpha/2} we need to find first the degrees of freedom, given by:

df=n-1=11-1=10

Since the Confidence is 0.90 or 90%, the value of \alpha=0.1 and \alpha/2 =0.05, and we can use excel, a calculator or a table to find the critical value. The excel command would be: "=-T.INV(0.05,10)".And we see that t_{\alpha/2}=1.81

Now we have everything in order to replace into formula (1):

65-1.81\frac{9}{\sqrt{11}}=60.09    

65+1.81\frac{9}{\sqrt{11}}=69.91

So on this case the 90% confidence interval would be given by (60.09;69.91)    

We are 90% confident that the true mean for the speeds of vehicles traveling on a highway is between 60.09 and 69.91 miles per hour.
