Answer:
The unlimited mileage plan would save money for Lia from 410 miles onwards.
Step-by-step explanation:
Since Lia can rent a van for either $ 90 per day with unlimited mileage or $ 50 per day with 250 free miles and an extra 25 ¢ for each mile over 250, to determine for what number of miles traveled in one day would the unlimited mileage plan save Lia money, the following calculation must be performed:
90.25 - 50 = 40.25
40.25 / 0.25 = 161
161 + 250 = 411
Therefore, the unlimited mileage plan would save money for Lia from 410 miles onwards.
Mathieu grows specialty tomatoes that are much larger than typical tomatoes. The distribution of their weights is strongly skewed to the left with a mean of 232g and a standard deviation of 12g. Suppose we were to calculate the mean weight from a random sample of 16 of Mathieu's tomatoes. We can assume independence between tomatoes in the sample.
What is the probability that the mean weight from the sample of 16 tomatoes x is within 6g of the population mean?
Answer:
We cannot calculate this probability because the sampling distribution is not normal.
Step-by-step explanation:
Since the parent population is not normally distributed, the small sample size will result in a sampling distribution that isn't normal.
In one U.S. city, the taxi cost is $5 plus $0.90 per mile. If you are traveling from the airport, there is an additional charge of $3.50 for tolls. How far can you travel from
the airport by taxi for $40.00?
Answer:
35 miles
Step-by-step explanation:
At the start, you lose $8.5 for tolls and the taxi cost.
You're left with $31.5 after that, every mile costs you $0.9, so you can go 31.5 : 0.9 = 35 miles.

What is the volume of this sphere?
Use a 3.14 and round your answer to the nearest hundredth.
6 yd
Answer:
Volume = 904.78 yards
Step-by-step explanation:
The formula for a sphere is:
V=4/3πr³
Since we already know that the radius is 3 yards and that π is 3.14 all we have to do is plug in the numbers.
V=4/3(3.14)(6)³
V=4/3(3.14)(216)
V=4.1897(216)
V≈904.78 yards

If point A, shown on the coordinate plane below, is reflected over both axes to create A’, what will be the coordinates of A’?
(-6, 3)
(-6, -3)
(6, -3)
(6, 3)
Answer:
(c) (6, -3)
Step-by-step explanation:
Reflection over both axes is the same as reflection across the origin, or rotation 180° about the origin. It has the effect of negating both coordinates:
(x, y) ⇒ (-x, -y) . . . . . reflection over both axes
The coordinates of A are (-6, 3), so the coordinates of A' will be ...
A(-6, 3) ⇒ A'(6, -3)

3x^2 + 300 = 0
Answer:
x = 10i - 10i
Step-by-step explanation:
3x^2 + 300 = 0
3(x^2 + 300) = 0
x^2 + 100 = 0
x^2 = -100
x = -100 (sqr root)
x = 10i - 10i

Write an equation of a line that passes through -4, -4 and 4,4
Answer: y=x
Step-by-step explanation:
The slope is (y2-y1)/(x2-x1) = 8/8 = 1
Plugging it into the equation y = mx+b:
y = x + b
Plugging in one of the coordinates:
4 = 4+b
b = 0
Therefore, the equation of the line is y=x
A bike with an original price of 90$ is discounted 40%. What is he sale price
Answer:
$54
Step-by-step explanation:
Original Price = $90
Discounted = 40%
Percent to decimal 40% = .40
$90 x .40=36 ( 36 is the Discount)
$90 - 36=54
Sale Price = $54
Hence, Sale Price = $54

from the definition of absolute value, |3x|= when x>=0
Explanation:
When x is zero or larger, then |x| = x.
An example: |9| = 9
This applies to |3x| as well, so |3x| = 3x when [tex]x \ge 0[/tex]

you have 5 apples, multiply it by x, and get 1345. What is x?
Answer:
x = 269
explanation:
5 apples multiplied by x and equals to 1345solve:
5 * x = 1345
x = 1345/5
x = 269
Therefore x is 269.
note: changing sides changes multiplication(*) to division(/) and division(/) to multiplication(*).
Answer:
x = 269
Step-by-step explanation:
For this question, they are asking you to create a problem out of the information given. For this problem, we will require the use of division. Before we can solve, we need to create the problem first.
Because the problem says 5 multiplied by x, we have to multiply these two. (Important:) Anytime you are multiplying a coefficient (5 in this case) by a variable (x in this case) we have to put the coefficient in front of the variable, like this:
5x _ ___.
Now that we know that, the question states that this basically equals 1345. With that said, that just gave us the rest of the problem. Now let's put it together:
5x = 1345.
Now we can solve. To single out the variable (x) to find our answer, divide 5 into 1345:
5x = 1345
5 5
So, 1345 ÷ 5 = 269. After that, we are left with x and 269 (because the 5 was canceled out with the division). So, the answer is:
x = 269.
I hope that this helps.

Of students in the AP curriculum at a prep school, 40% take one AP exam, 45% take two AP exams, and the remaining 15% take 3 AP exams. The highly desirable score of 5 is hard to earn, and only 20% of these students will earn a 5 on any given exam they take. Assuming their results on each exam are independent, what is the probability a student in the AP curriculum will earn at least one 5
It should be noted that the probability that a student will earn at least one 5 will be 0.3152.
How to calculate the probabilityTest P(x). P(at least one 5)
1. 0.4. 0.2
2. 0.45. 0.36
3. 0.15. 0.488
Therefore, the probability that a student in the AP curriculum will earn at least one 5 will be:
= (0.4 × 0.2) + (0.45 × 0.36) + (0.15 × 0.488)
= 0.3152
In conclusion, the correct option is 0.3152.

3 of those pieces represent half the circle (3/6 = 1/2)
2 more pieces represent one third (2/6 = 1/3)
