500*40%=200
500-200=$300 is the actual cost with the discount
Answer:
The answer is A (i just took the test)
Step-by-step explanation:
Answer: The outcomes do not appear to be equally likely, so a uniform probability model is not a good model to represent probabilities in Pilar's experiment
The outcomes are: 1 2 3 4 5
The Relative Frequency: 0.05 0.35 0.26 0.13 0.21
As you can see the outcomes do not appear to be equally likely since 0.05 and 1 are not close in number range along with the other options
Answer: |81-x|<5
Step-by-step explanation:
Given: Temperature of an enclosure for a pet corn snake should be an average of 81° F.
Temperature in the enclosure should not vary by more than 5° F.
Let x= Temperature in the enclosure
Then, difference between average and current temperature should less the 5.
i.e. |81-x|<5 (required absolute value equation )
hence, the absolute value equation could be used to determine the minimum and maximum temperatures recommended for the corn snake enclosure:
|81-x|<5
Answer:
Step-by-step explanation:
You would require the table with the number of males and females who prefer either pink or yellow lemonade at the state fair.
Pink Lemonade Yellow Lemonade TOTAL
Male 156 104 260
Female 72 48 120
TOTAL 228 152 380
P(pink lemonade | female) = 72 / (48 + 72) = 72 / 120 = 0.6
P(pink lemonade) = (156 + 72) / (156 + 72 + 104 + 48) = 228 / 380 = 0.6
Therefore, The event "prefers pink lemonade" and "female" are independent because P(pink lemonade | female) = P(pink lemonade) = 0.6
-17 is less than -1 so you will use the less than sign (<)
Answer: 17 __<__-1
< is less than
> is greater than
= is equal to
<span>≥ is greater than or equal to</span>
