Step-by-step explanation:
Option D is the correct answer
Because if the blouse is of 8 dollars then 4 blouses = 32 and skirt = 12 so 3 skirts = 36
36 + 32 = 68
Susan bought 6 blouses = 8 x 6 = 48
3 skirts = 12 x 3 = 36
48 + 36 = 84
50% or 1/2 of 4 is 2 50% or 1/2 of 6 is 3 so then just add them to the respective number since its going up by 50% or 2 in by 3 in \[\frac{ 6 }{ 9}\]
Step-by-step explanation:
<u>Step 1: Convert into expressions</u>
y = one-fourth x minus 1 → 
y = negative one-half x minus one-fourth → 
They intersect at 
Answer: Option A, (1, negative three-fourths)
Well, let us solve this step by step.
We know that Michelle earns 349 plus 3% of the Purchase
price. Let us call the Purchase price as P, so that:
Earnings, E = 349 + 0.03 P
So if she earns 8,965 (E = 8,965) so we can find P:
8,965 = 349 + 0.03 P
0.03 P = 8,616
P = $287,200
Answer:
Null hypothesis: ∪ = $7,000
Step-by-step explanation:
The null hypothesis is a general statement that there is no relationship between two measured instances or no association among groups.
In this case, the sales of a grocery store had an average of $7,000 per day is the null hypothesis. Then the research was carried out to test for the effectiveness of the advertising campaigns in increasing sales.
Thus, this is the alternative hypothesis. The researchers wish to test against the null with regards to the involvement of the advertising campaigns.
Thus, the null hypothesis is just the average sales without the advertising campaigns which is
Null hypothesis: ∪ = $7,000
Alternative hypothesis: ∪ ≠ $7,000
