Use the quadratic formula to solve for x.
3x2 + 2x - 6 = 0
Answer:
x = 1/3 (sqrt(19) - 1) or x = (1/3 (-1 - sqrt(19)))
Step-by-step explanation:
Solve for x over the real numbers:
3 x^2 + 2 x - 6 = 0
Using the quadratic formula, solve for x.
x = (-2 ± sqrt(2^2 - 4×3 (-6)))/(2×3) = (-2 ± sqrt(4 + 72))/6 = (-2 ± sqrt(76))/6:
x = (-2 + sqrt(76))/6 or x = (-2 - sqrt(76))/6
Simplify radicals.
sqrt(76) = sqrt(4×19) = sqrt(2^2×19) = 2sqrt(19):
x = (2 sqrt(19) - 2)/6 or x = (-2 sqrt(19) - 2)/6
Factor the greatest common divisor (gcd) of -2, 2 sqrt(19) and 6 from -2 + 2 sqrt(19).
Factor 2 from -2 + 2 sqrt(19) giving 2 (sqrt(19) - 1):
x = 1/6(2 (sqrt(19) - 1)) or x = (-2 sqrt(19) - 2)/6
In (2 (sqrt(19) - 1))/6, divide 6 in the denominator by 2 in the numerator.
(2 (sqrt(19) - 1))/6 = (2 (sqrt(19) - 1))/(2×3) = (sqrt(19) - 1)/3:
x = (1/3 (sqrt(19) - 1)) or x = (-2 sqrt(19) - 2)/6
Factor the greatest common divisor (gcd) of -2, -2 sqrt(19) and 6 from -2 - 2 sqrt(19).
Factor 2 from -2 - 2 sqrt(19) giving 2 (-sqrt(19) - 1):
x = 1/3 (sqrt(19) - 1) or x = 1/6(2 (-1 - sqrt(19)))
In (2 (-sqrt(19) - 1))/6, divide 6 in the denominator by 2 in the numerator.
(2 (-sqrt(19) - 1))/6 = (2 (-sqrt(19) - 1))/(2×3) = (-sqrt(19) - 1)/3:
Answer: x = 1/3 (sqrt(19) - 1) or x = (1/3 (-1 - sqrt(19)))

3. Suppose a retail business sale its commodities at a margin of 25% on all items purchased and sold. Moreover the company uses 5% commission as selling expense and Birr 12,000 as a Fixed Cost, then Find the Breakeven revenue for the retail business after developing the equation
The Breakeven revenue for the retail business is Birr 12,500
What is breakeven?
Breakeven is the point at which the revenue is equals to the cost, hence the profit is zero.
Revenue = Cost
Let x represent the number of items sold, hence:
Revenue = (100% + 25%) of x = 1.25x
Cost = 5% of x + 12000 = 0.05x + 12000
At breakeven:
1.25x = 0.05x + 12000
x = 10000
Hence:
Revenue = 1.25(10000) = Birr 12,500
The Breakeven revenue for the retail business is Birr 12,500

Answer:
Never
Step-by-step explanation:
It should be never since as the value of x increases, so does y.
If the y value increases as x increases, the function is said to be increasing.
If the y value decreases as x increases, the function is said to be decreasing.

What is the probability of picking an orange marble and flipping tails?
Solution:
First let see how many orange marbles are there:
As we can see there is 1 orange marble out of 7 total. The probability of picking an orange marble is 1/7.
Now let see how many side a coin have:
As we can see the probability of flipping tails is 1/2 because 1 side is tails out of 2 sides total.
Now multiply both together:
(1/7)× (1/2) = (1×1)/(7×2) = 1/14
This represents the probability of getting an orange marble and flipping tails.
In additionally 1/14 can't be simplify anymore.
Kavinsky
Answer:
[D] 1/14
Step-by-step explanation:
Knowing that there are 5 purple marbles, 1 brown marble, 1 orange marble. Since, on the given question all we need to know is the total marbles and the orange marbles.
Which the probability is 1/7
Now for the coin.
Knowing that there are two sides on a coin
Heads and tails (1/2)
Which is only 1/2 also known as 50% probability.
Now multiply straight across:
1/2 × 1/7
⇒ 1 × 1 = 1
⇒ 2 × 7 = 14
Thus, the answer is 1/14
can't be farther simplify.

Melissa deposits $5000 into an account that pays simple interest at a rate of 4% per year. How much interest will she be paid in the first 2 years?
Answer:
$400 is the intrest she will pay in the first 2 yrs
Step-by-step explanation:
principal (p) = 5000
time (t) = 2yrs
rate (r) = 4%
Now,
Intrest(I) = p×t×r/100
= 5000×2×4/100
= 400$

If the data for the heights of players on a basketball team is skewed right, which statistical measure represents the spread of the data best?
A. Interquartile Range
B. Mean
C. Median
D. Range
Answer:
Median
Step-by-step explanation:
I know that you can't do Range, since it's skewed right.
The mean can't be it since it's also not representative when it's skewed right.
I'd say Median, or IQR at first glance but if you look at a graph, the IQR might follow with the skewed and move over a bit.
That leaves Median.
The correct statistical measure which represents the spread of the data best is, Median.
Given that;
The data for the heights of players on a basketball team is skewed right.
Since, We know that;
For the data for the heights of players on a basketball team is skewed right,
We can use Median for the spread of the data best.
Hence, The correct statistical measure which represents the spread of the data best is, Median.

The first night the individual sold 45 Senior tickets and 92 Adult tickets. The second night, the individual sold 26 Senior tickets and 45 Adult tickets. Which night did the individual sell a higher ratio of Senior tickets to Adult tickets?
Step-by-step explanation:
the ratio senior to adult tickets on the first night :
45/92
the ratio on the second night :
26/45
which ratio is higher ? that means we have to determine which fraction is bigger.
the simplest and fastest way to compare them is to bring them to the same denominator (bottom part).
and the simplest way to do that is simply by multiplying the numerator and denominator of each fraction by the denominator of the other fraction :
45/92 × 45/45 = 2025 / 4140
26/45 × 92/92 = 2392 / 4140 (this is therefore bigger)
so, the ratio on the second night is higher.
