Answer:
Week 4
Step-by-step explanation:
A week consist of 7 days (MO, TU, WE, TH, FR, SA, SU)
The mean of the sells done by the store is calculated as the following:
(MO+TU+WE+TH+FR+SA+SU ) 1/7
If we calculate the mean of every given week we have this
Week 1: 6.57
Week 2: 8.86
Week 3: 2.28
Week 4: 8
Since a typical day the jewelry store sells 8 bracelets, in a typical week, the mean of bracelets sold is 8.
The week 4 is the best estimate of the jewelry store's weekly sales throughout the year.
Step by step solution :
Step 1 :
Equation at the end of step 1 :
(0 - (26 • (b2))) + (0 - 33b2)
Step 2 :
Equation at the end of step 2 :
(0 - (2•13b2)) + -33b2
Step 3 :
Final result :
-53b2
Question: How do I do fractions and proportions?
Answer: To solve this proportion, you have to cross multiply, and to do fractions, make sure the bottom numbers (the denominators) are the same, and the top numbers (the numerators) put that answer over the denominator, and simplify if need be.
Hope this helps, have a good day. c;
One operator is missing. I will assume it is a + and that the equation is: 4y -2/5y +4/5 = -3
Solution step by step
1) Sum -4/5 to both sides
4y - 2/5y + 4/5 - 4/5 = -3 -4/5
2) Sum alike terms
18/5 y = -19/5
3) Multiply both sides by 5
18 y = -19
4) Divide both sides by 18
y = -19/18
