A rationla power is a power in form a/b

remeber these 2 simple rules
1. x^{-m}=\frac{1}{x^m}
2. x^\frac{m}{n}=\sqrt[n]{x^m}

and the combo of these
x^\frac{-m}{n}=\frac{1}{\sqrt[n]{x^m}}

that's all

P(<br> b.=15/16,p(a and <br> b.=3/4 find p(a
Bess [88]
And or both means we multiply the given probability situations that are mutually exclusive and exhaustive - they cannot occur at the same time.

let P(a)=x

then: P(b) * P(a) =3/4

         15/16 * x = 3/4

          15x/16 = 3/4
therefore x= 3/4 *16/15
          x = 4/5
P(a) = 4/5

hope it's clear

A video game company surveys a random sample of 225 of its best customer and finds that the average gamer spends $406 a year on
Burka [1]
The second survey is more believable because there is randomness in the second rather than the first survey. Since the second company surveyed in all interest levels while the first company only surveyed their best customers. Random sampling like what the second company did helps produce representative samples by removing voluntary response bias and undercover age bias.

For a t distribution with 16 degrees of freedom, find the area, or probability, in each region. (to 2 decimals)
Fiesta28 [93]

Answer:

The area to the right of 2.120 is 0.0250 rounded to 4 decimal places

Step-by-step explanation:

We are required to find P(t>2.120)

To find this area we have to use the t distribution. Also we can use technology like excel to find the area to the right of 2.120.

The excel function is:

=TDIST(2.120,16,1)=0.0250

Where:

2.120 is the value of the test statistic

16 is the degrees of freedom

1 denotes the one tailed.

Therefore, the area to the right of 2.120 is 0.0250
