47 times 22 = 1034
1034/2 = 517
380 is less than 517 so Renee has more than enough for each student.
Answer:
<h2>$38.4</h2>
Step-by-step explanation:
Step one:
we are told that the price online is $39.99
and that the discount is 10%
and also tax is 6%
Step two:
discount
let us solve for the deduction first
=10/100*39.99
=$3.99
Tax
=6/100*39.99
=$2.4
The final cost= cost online-10% discount+6% tax
Final cost= 39.99-3.99+2.4
Final cost = $38.4
Let the number be x
(9+2x)×2= (-3x)+4
18+4x=-3x+4
4x+3x=4-18
7x=-14
x=-2
Answer:what equation
Step-by-step explanation:
Answer:
A researcher is interested in comparing the usage of bank debit cards by consumers in rural (r) and urban (u) areas. Each year for the past five years, she has surveyed 500 individuals (one‑half urban, one‑half rural) randomly selected from across the United States. She is specifically interested in any differences that may exist between the two groups with regard to usage. The results of the current study indicate that people in urban areas use bank debit cards 12 times per month on average, while those in rural areas use bank cards 10 times per month on average. Which of the following is the null hypothesis that the researcher should use in comparing the usage rates?
Option C is the correct answer.
Step-by-step explanation:
The null hypothesis is the hypothesis of no difference. Therefore, the appropriate null hypothesis will be:
There is no difference in the average monthly usage of debit cards between urban and rural people.
Therefore, option C is the correct answer.
