So ill show you how i like to do these problems. First change the percentage into a decimal 20%= 0.20. 45*.2= 9. So its $9.00 off and the total price is $36.00

<u><em>function </em></u>: p(x) = 65 + 25(x)

for 3 sells

  • p(3) = 65 + 25(3)
  • p(3) = 140

for 10 sells

  • p(10) = 65 + 25(10)
  • p(10) = 315

So,

140 ≤ p(x) ≤ 315

What are the hypotheses for testing to see if a correlation is statistically significant?
Andrew [12]

Answer:

Step-by-step explanation:

For testing of significance of correlation coefficient denoted by r, we create hypotheses in three ways

They are one tailed, two tailed.  One tailed can be stated as right tailed and also left tailed.

The null hypothesis would normally be as r=0

Verbally we can say this there is no association between the dependent and independent variable (linear)

Against this alternate hypothesis is created as

either r not equal to 0

or r>0 or r<0

If r not equal to 0, we say two tailed hypothesis test

If r>0 is alternate hypothesis, it is right tailed test

If r<0 is alternate hypothesis, then it is left tailed test.

70,000 devided by 7,000
marusya05 [52]
It would be 10 because 7000 can go into 70,000 10 times. You can you a calculator or look at the zeros take away the 3 zeros in 7000 and then 3 zeros in 70,000 making it 7 and 70 and 7 goes into 70 10 times as well. I hope this helps!

Find the indicated angle measures. Then justify the answer. ​
ExtremeBDS [4]
Pretty sure it’s 65 since its alternate interior angles which equal 180
