Answer:
$925
Step-by-step explanation:
First you need to understand what does "profit" mean. When you sell something, you need to get the balance between the money you spend on the item and the money you've earned by selling it.
So, profit= sale price(Ps) - purchase price(Pp)
For one item:
Ps=$13.99 and Pp=$10.29
Profit= $13.99 - $10.29 = $3.7
Now, in the question, we are asked about 250 items. As every item has the same price, the profit is the same for each one. Then, it is 250 times the profit of one item.
For 250 items:
Profit= 250 × $3.7= $925
Answer:
The appropriate hypothesis set for Andraya to test is:
Step-by-step explanation:
The makers of the game claim that the wheel has an equally likely probability of landing on each section.
That is, the makers claim that the probability of earning the grand prize is:
Andraya has played the game for several months and believes that the grand prize occurs less often than the game makers claim.
At the null hypothesis, we test if it happens as often as the makers claim, that is, the proportion is 0.125. So
At the alternate hypothesis, we test if it happens less ofter than the makers claim, that is, the proportion is less than 0.125. So
The appropriate hypothesis set for Andraya to test is:
Answer:
x=-45
Step-by-step explanation:
-x/3=15
-x=15×3
=45
Hence, x=-45.
