BaLLatris [955]3 years ago

Answer:

Look again at the equation y = a sin (bx + c). Notice that we have varied a, the amplitude, and b, the period. ... In the first equation, y = sin x, c is equal to zero. Look at the graph on the left to see that curve as well as the curve of the equation y = sin (x + 2).

What is a common denominator of 1/2 and 1/4
attashe74 [19]
<span>If you're trying to rewrite 1/2 and 1/4 in terms of the same common denominator, all you have to do is multiply the top and bottom of 1/2 by 4 (which is the denominator of 1/4) and the top and bottom of 1/4 by 2 (which is the denominator of 1/2) to find that 1/2 = (1 x 4) / (2 x 4) = 4/8 and 1/6 = (1 x 2) / (4 x 2) = 2/8.</span>

neonofarm [45]

Answer:

\bar X = \frac{\sum_{i=1}^n X_i f_i}{n}= \frac{1394}{88}=15.8

s^2 = \frac{88(32372) -(1394)^2}{88(88-1}=118.3

Sd(X) = \sqrt{118.273}=10.9

Step-by-step explanation:

Previous concepts

In statistics and probability analysis, the expected value "is calculated by multiplying each of the possible outcomes by the likelihood each outcome will occur and then summing all of those values".

The variance of a random variable Var(X) is the expected value of the squared deviation from the mean of X, E(X).

And the standard deviation of a random variable X is just the square root of the variance.  

Solution to the problem

For this case we can calculate the properties required with the following table:

Interval     Mid point (x)     f           x*f         x^2 *f

_________________________________________

1-10               5.5               40        220         1210

11-20             15.5              15        232.5       3603.75

21-30            25.5             23       586.5       14955.75

>31                35.5             10        355          12602.5

________________________________________

Total                                 88        1394         32372

We assume that the mid point for the class >31 is 35.5 using the problem information.

For this case the expected value would be given by:

\bar X = \frac{\sum_{i=1}^n X_i f_i}{n}= \frac{1394}{88}=15.8

The variance owuld be given by this formula"

s^2 = \frac{n(\sum x^2 f) -(\sum xf)^2}{n(n-1}

And if we replace we got:

s^2 = \frac{88(32372) -(1394)^2}{88(88-1}=118.3

The standard deviation would be just the square root of the variance:

Sd(X) = \sqrt{118.273}=10.9

Nastasia [14]

Answer: 20 names from each grade

Step-by-step explanation:

The two answers it comes down to are between every student from all of her classes and 20 students from each grade, however since the poll wants to determine how many people across the entire student body would attend, pulling from just Miranda's classes would add a grade level bias to the dance and would not be entirely random. 20 students from each grade is completely unbiased and properly represents the entire student body.
