hi

technique is  to decompose both part of the fraction ( in prime numbers if possible )

 8 * 5/6   =     2*4*5  / 3*2   =   20/3

A company rounds its losses to the nearest dollar. The error on each loss is independently and uniformly distributed on [–0.5, 0
lesya [120]

Answer:

the 95th percentile for the sum of the rounding errors is 21.236

Step-by-step explanation:

Let consider X to be the rounding errors

Then; X \sim U (a,b)

where;

a = -0.5 and b = 0.5

Also;

Since The error on each loss is independently and uniformly distributed

Then;

\sum X _1 \sim N ( n \mu , n \sigma^2)

where;

n = 2000

Mean \mu = \dfrac{a+b}{2}

\mu = \dfrac{-0.5+0.5}{2}

\mu =0

\sigma^2 = \dfrac{(b-a)^2}{12}

\sigma^2 = \dfrac{(0.5-(-0.5))^2}{12}

\sigma^2 = \dfrac{(0.5+0.5)^2}{12}

\sigma^2 = \dfrac{(1.0)^2}{12}

\sigma^2 = \dfrac{1}{12}

Recall:

\sum X _1 \sim N ( n \mu , n \sigma^2)

n\mu = 2000 \times 0 = 0

n \sigma^2 = 2000 \times \dfrac{1}{12} =  \dfrac{2000}{12}

For 95th percentile or below

P(\overline X <  95}) = P(\dfrac{\overline X - \mu }{\sqrt{{n \sigma^2}}}< \dfrac{P_{95}- 0 } {\sqrt{\dfrac{2000}{12}}}) =0.95

P(Z< \dfrac{P_{95} } {\sqrt{\dfrac{2000}{12}}}) = 0.95

P(Z< \dfrac{P_{95}\sqrt{12} } {\sqrt{{2000}}}) = 0.95

\dfrac{P_{95}\sqrt{12} } {\sqrt{{2000}}} =1- 0.95

\dfrac{P_{95}\sqrt{12} } {\sqrt{{2000}}} = 0.05

From Normal table; Z >   1.645 = 0.05

\dfrac{P_{95}\sqrt{12} } {\sqrt{{2000}}} =1.645

{P_{95}\sqrt{12} } = 1.645 \times {\sqrt{{2000}}}

{P_{95} = \dfrac{1.645 \times {\sqrt{{2000}}} }{\sqrt{12} } }

\mathbf{P_{95} = 21.236}

the 95th percentile for the sum of the rounding errors is 21.236

What is the answer to this somebody!!!
Galina-37 [17]

So with this, you'll be using a proportion to solve it. And here's what your equation will look like:


\frac{30}{x} =\frac{x}{24}


Firstly, you'll need to cross-multiply. Your equation will look like this: 720=x^2


For this, all you need to do is square root, and your answer is \sqrt{720} =x, however this answer can be simplified further.


\sqrt{720} =\sqrt{30*24} =\sqrt{5*6*6*4}=\sqrt{5*3*2*3*2*2*2} =4*3\sqrt{5} =12\sqrt{5}


In short, your answer is 12\sqrt{5}

Sami took six quizzes in science class. The grades for the quizzes are 86, 92, 79, 96, 80, and 95. What is the median grade?
mart [117]

Answer:

The median grade would be 89

Step-by-step explanation:

To find the median, first put the numbers all in ascending order.

79, 80, 86, 92, 95, 96

Now isolate the middle term or terms. Since there is an even amount of numbers, we pick the two in the middle. To find the median, we take an average of those terms.

(86 + 92)/2 = 89
