Q.Find the selling price if the cost price is $1200 and loss percent is 25?

Write in step by step ​

Answers

Answer 1

Step-by-step explanation:

C.p=1200

loss percent=25

s.p=?

s.p=100- loss×C.p/100

s.p=100- 25×1200/100

S.p=75×1200/100

s.p=90000/100

s.p=900

Perpendicular slops come from reversing the numerator and denominator and making it negative so the new slope would be:

m=-4/5

Then you use point slope formula and plug in your values:

y-y1=m(x-x1)

y-1=-4/5(x-1)

y=(-4/5)x+9/5

What is the difference between a tax credit and a tax deduction?

Answers

Answer:

A deduction can only lower your taxable income and the tax rate that is used to calculate your tax. This can result in a larger refund of your withholding. A credit reduces your tax giving you a larger refund of your withholding, but certain tax credits can give you a refund even if you have no withholding.

Step-by-step explanation:

Computer use.
A random sample of 197 12th-grade students from across the United States was surveyed, and it was observed that these students spent an average of 23.5 hours on the computer per week, with a standard deviation of 8.7 hours. If we plan to use these data to construct a 99% confident interval, the margin of error will be approximately.

(a.) 0.07
(b.) 0.62
(c.) 1.6
(d.) 8.7

Answers

Answer:

The margin of error will be approximately =

(c.) 1.6

Step-by-step explanation:

Sample of 12th-grade students = 197

Average hours spent on computer per week = 23.5 hours

Total hours spent = 4,625 (197 * 23.5) hours

Standard deviation = 8.7 hours

Confidence interval = 99%

Square root of sample size = [tex]\sqrt{x}[/tex] = 14.04

Standard deviation/square root of sample size = 8.7/14.04 = 0.6196

Z value at 99% confidence = 2.58

Margin of error = 0.6196 * 2.58

= 1.59857

= 1.6

This question can be determined by the  concept of standard deviation. The margin of 1.6 error will be approximately.

 

Given:

Random sample of 12th-grade students = 197

Average hours spent on computer per week = 23.5 hours

Therefore,

Total hours spent by 12th grade students  = [tex]\bold{(197 \times23.5=4629.5)hours}[/tex]  

Standard deviation = 8.7 hours (Given)

Confidence Interval =99% (Given)

 

Square root of  random sample size =  = 14.04

[tex]\bold{\dfrac{Standard\: deviation}{Square\: root\: of\: sample\: size} =\dfrac{8.7}{14.04 } = 0.6196}[/tex]

 

Therefore,

Z value at 99% confidence = 2.58

Margin of error = [tex]0.6196 \times2.58[/tex]  

                          = 1.59857 error

                          = 1.6 error

Thus, the correct option is (c) 1.6 error.

Amber is an engineer designing a suspension bridge. She has a tower at each end of the bridge that will hang four diagonal cables. Her design is shown. Explain the process she should use to determine the lengths of her cables. Use complete sentences.

Answers

Answer

she should find the length from where the tower begins to where the cable touches the ground, and use that number to be leg B, with the hight of the tower being constant and being leg A. then she uses the two numbers to find the hypotenuse of the new triangle. Repeat this with the other 3 cables and you have the answer! (Note: leg A's length will remain constant, but leg B's length will not because it is reliant on how far away the cables contact the ground in relation to the tower.)

Answer:

  no; 1+1=2, a number not in the set

Step-by-step explanation:

A set is closed under addition if the addition of any two members of the set results in a member of the set.

  0 + 0 = 0 . . . in the set

  0 + 1 = 1 . . . in the set

  1 + 0 = 1 . . . in the set

  1 + 1 = 2 . . . not in the set. The set is not closed under addition.

Why are post hoc test preferred over several t-test

Answers

Almost all the post-hoc paired comparisons are variations on t test, but basically the difference between post hoc paired comparisons from t test is the way that the standar error is estimated. On t test the standard error between two groups is easily calculated, but what happen when you have three or more groups? Then you must to perform an ANOVA test, and this gives you the answer to the standard error: the mean square of error (within groups) can be used to estimate this, and all post-hoc procedures uses this value in its calculus.
