Remember
(ab)(cd)=(a)(b)(c)(d)=(ac)(bd),
and
(x^m)(x^n)=x^(m+n)
(9x^2y^3)(7xy^2)=
(9)(x^2)(y^3)(7)(x)(y^2)=
(9)(7)(x^2)(x)(y^3)(y^2)=
(63)(x^3)(y^5)=
63x^3y^5
Answer:
The probability of having high cholesterol = 0.496
Step-by-step explanation:
Given frequency data table
cholesterol level
Normal <em> High </em> Total
Heart diseases Yes 11 223 234
<u> No 367 149 516</u>
<u>Total 378 </u><em><u> 372 </u></em><u> </u><em><u> 750</u></em>
<em><u /></em>
<em>Given data </em>
<em>The </em> Cholesterol level is high n ( High cholesterol) = 372
Total n( S) = 750
The probability of having high <em>cholesterol level</em>
<em> P( E) = </em><em></em>
You question is of two parts.
For the first part:
<span>A group of men and women were asked what their favorite pet was, and the results of the survey were tabulated.
</span>Let event A be defined as randomly
choosing someone who picked cats or dogs as their favorite pet. Let
event B be defined as a randomly
chosen person being male.
Find P(B| NOT A).
P(A) = P(choosing cat) + P(choosing dog) =
P(NOT A) =
P(B and NOT A) = P(males that did not choose cat or dog) =
P(B | NOT A) =
For the second part of the question.
<span>Petey
is considering investing $19 in a certain company. Financial advisors
forecast that there is a 30% chance that the stock will increase in
value by 10%, and a 70% chance he will lose his initial investment.
Determine if Petey should make the investment, and find the expected
value of the investment.
If his investment increases by 10%, the value of the investment will be 1.1 x $19 = $20.90 with a probability of 30% or 0.3
The expected value of the investment is given by
Therefore, Petey should not make the investment as there is an expectation of a loss from the investment.

Depending on if you're solving for X or Y:
X less than or equal to 4y/3 -5
Y greater than or equal to 3x/4+15/4
Okay <em>we need to know the number of degrees in this shape first</em> in order to find x.
The formula to find the # of degrees in any polygon is
180 ( n - 2 )
n = the number of sides the figure has
This figure has 8 sides
180 ( 8 - 2 )
180 (6) = 1080°
This figure is 1080°
To find x, let's <u>subtract all the other degrees</u> they gave us
<em>1080° - 124° - 136° - 132° - 129° - 116° - 158° - 141° = 144°</em>
x = 144°
I hope I helped!
