At the beginning of the day the stock market goes down 50 1/2 points and stays at this level for most of the day. At the end of
IrinaK [193]

Answer:

<h2>The change for the day is 29 3/4</h2>

Step-by-step explanation:

In this problem, we are expected to calculate the change in the price of a particular stock

Given that the days high is 80 1/4

and also that the days low is 50 1/2

we can calculate the change by subtracting the days low from the days high

i.e 80 1/4- 50 1/2= 321/4-101/2= (321-202)/4= 119/4 = 29 3/4

<em>hence the change for the day is 29 3/4</em>

Also we can calculate the percentage change as

%change = (high-low)/low*100

%change= 80 1/4- 50 1/2/50 1/2= 29 3/4/50 1/2 *100

%change= 119/4*2/101 *100= 119/202*100= 0.589*100= 58.9%

%change= 58.9%

How do you do prime factorisation for 48/72?
Mrac [35]
48:
48/2 = 24 24/2 = 12 12/2 = 6 6/2 = 3
 We can not divide by 2, but we can divide by 3: 3/3 = 1
  That's as far as we go. So I divided by 2 four times and once by 3: Therefore: 48 = 2 * 2 * 2 * 2 * 3
 Now we take 72
 72 / 2 = 36 36 / 2 = 18 18 / 2 = 9 Nine is not divisible by 2, but it is by 3, so: 9 / 3 = 3 3 / 3 = 1
 That's as far as we can go. I divided by 2 three times and by 3 two times. Therefore 72 = 2 * 2 * 2 * 3 * 3 So, taking the bigger picture:
<span><span>4872</span>=<span><span>2∗2∗2∗2∗3</span><span>2∗2∗2∗3∗3</span></span></span> Now three two's cancel out and one three cancels out and we get <span>2\3
answer=2\3</span> <span>

consider an infinite set of pairwise independent random variables which are uniformly distributed between 0 and 1. what's the ex
r-ruslan [8.4K]

When two random variables X and Y are considered to be independent, it means that neither X's distribution nor Y's values have any bearing on the other.

<h3>What do you mean by independent random variable?</h3>

A random variable is a variable used in an experiment, such as the number of coin tosses or card draws. An independent random variable is a random variable in your experiment that doesn't affect the other random variables. In other words, it has no impact on the likelihood that another event will occur. For illustration, suppose you randomly selected 50 bags of sugar from various grocery stores in order to determine the average weight of a bag of sugar. The factors are independent since you wouldn't anticipate the weight of one bag having an impact on another. A dependent random variable, on the other hand, does have an impact on the probability of other random variables.

What percent of 150 is 162
Novay_Z [31]
To find a percentage of a number, you divide by that number.
So to find what percent of 150 162 is, you divide 162 by 150
162 ÷ 150 = 1.08
Now, to find the percentage, we take the decimal and move the point two places to the right.
1.08 = 108%
162 is 108% of 150.
