Answer:
10
Step-by-step explanation:
-3 = 7 - x
Add x to both sides
x -3 = 7 - x +x
x - 3 = 7
Now, add 3 to both sides
x - 3 + 3 = 7 + 3
x = 10
Answer:
B 10% off sale, with a total price to pay of 756
Step-by-step explanation:
Retail price (Rp) = $800
Taxes (T) = 5%
- Offer A $75 instant rebate
Total price A (TA) = Rp - 75 + (Rp - 75) 5%
TA = 800 - 75 + (800-75) 5%
TA = 725 + 725 5%
725 5% = 725*5/100 = 36.25
TA= 725+36.25 = $761.25
Total price B (TB) = RP - RP 10% + (RP - RP 10%) 5%
TB = 800 - 800 10% + (800 - 800 10%) 5%
800 10% = 800*10/100 = 80
TB = 800 - 80 + (800 - 80) 5%
TB = 720 + 720 5%
720 5% = 720*5/100 = 36
TB = 720 + 36 = $756
- Offer C 5% off sale plus store pays sales tax
store pays sales tax means Walden's family will not need pay for taxes
Total price C (TC) = RP - RP 5%
TC = 800 - 800 5%
800 5% = 800*5/100 = 40
TC = 800 - 40 = $760
- Offer D a “no tax” sale—the store pays the tax
Means that Walden's family will need pay just the retail price
TD = $800
The beast deal is from the store B
Umm, I think it is the first one.
Answer:
0.15401
Step-by-step explanation:
Given that test statistic = 3.7408
From the question, we could deduce that, this is scenario could be analysed A ONE - WAY analysis of Variance method as it has one independent variable, Age subdivided into 3 levels
The test statistic value obtained is the Chisquare (χ²) value, which equals 3.7408
To Obtain the requested Pvalue, we need the degree of freedom, which is :
(Number of columns - 1) * (number of rows - 1)
Number of candidates = 2
Number of levels = 3
Hence,
Degree of freedom = (3 - 1) * (2 - 1) = 2 * 1 = 2
Using the Chisquare Pvalue calculator or distribution table :
χ²;3.7408, 2 = 0.154062
Pvalue = 0.1541
