Answer: Third quartile =$21.58
Step-by-step explanation:
Let x be value of a stock .
For uniform distribution,
probability density function =
Let a be the stock value such that P(x<a) =75% or 0.75
Hence, 75% of all days the stock is below $21.58 or Third quartile =$21.58 .
Answer:
x = 4 , y = 2
Step-by-step explanation:
Using the sine / tangent ratios in the right triangle and the exact values
sin60° = and tan60° = , then
sin60° = = = ( cross- multiply )
x = 4 ( divide both sides by )
x = 4
and
tan60° = = = ( multiply both sides by y )
y = 2 ( divide both sides by )
y = 2

Answer:
9/10
Step-by-step explanation:
If you are truly "struggling," you might want to consider working the problem using your calculator. It will give you a decimal answer: 0.9.
You know this is nine tenths, or 9/10 when written as a fraction.
__
When adding fractions, you are instructed to use a common denominator. Usually, that instruction is to find the "least" common denominator. In many cases, that simplifies reducing the fraction that will be the answer.
However, <em>any</em> common denominator will do. The easiest one to find is the product of the denominators. Here, that is 2·5 = 10.
The first fraction has a denominator of 2, so to make its denominator 10, you need to multiply it by 5/5.
The second fraction has a denominator of 5, so to make its denominator 10, you need to multiply it by 2/2.
__
Effectively, we have used the formula for the sum of two fractions:
(a/b) +(c/d) = (ad +bc)/(bd)
1/2 + 2/5 = (1·5 +2·2)/(2·5) = 9/10
Hello.
The Manager has concluded that 2 out of 25 light bulbs are faulty.The table he created represents the ratio of bulbs checked and which ones were found faulty.
A way that he could verify that the table is correct is by simplifying each ratio. If each of them turn out to 2:25, then the conclusion is correct.
The best answer that matches this is answer choice "C.)" as it also defines our method of verifying the table's validity (just the order of the ratio is reversed, and that's fine as long as the variables are matching as well). We can further prove that this answer is correct by making ratios of our table and simplifying them;
100:8; divide both sides by 4.
25:2
500:40; divide both sides by 20.
25:2
2,000:160; divide both sides by 80.
25:2
This ratio is always the simplified answer.
Your answer is: "C.)"
I hope this helps!
