Answer:
(a)0.34
(b)0.5
(c)0.185
(d)0.544
(e)0.655
(f)Not disjoint events
(g)Independent events
Step-by-step explanation:
The summary of education levels among party lines is given in the table below
(a)Probability a randomly selected participant has a college degree.
The probability a randomly selected participant has a college degree is:
(b)The probability that a randomly selected participant is a democrat.
(c)The probability that a randomly selected participant is a democrat and has a college degree.
(d)Probability of being a democrat given that the participant has a college degree.
(e)The probability of begin a democrat or having a college degree
Number of Democrats =100
Number of Those with College degrees = 68
Number of democrats with College degrees =37
Therefore:
Probability of begin a democrat or having a college degree
(f)The event of having a college degree and being a democrat are not disjoint events as there are some democrats who have a college degree.
(g)The event of having a college degree and being a democrat are independent events as the outcome of one does not affect the other.
4xy-3y=12
y(4x-3)=12
y=12/(4x-3)
The summation of the money Myla spend altogether is $41.9
As in the given problem we can see Myla bought
a shirt for $25.36 and
a hat for $5.09 and
a belt for $11.45.
Hence we need to know the cummulative price she spend altogether.
To get the total price we should add the price of shirt hat and belt.
Summing all the prices we get
$25.36+$5.09+$11.45=$41.9
As all the quantities are given in one currency thus we can add them by simple addition formula.
Thus she spend $41.9 altogether at the mall.

Answer:
Step-by-step explanation:
The given equation is 
We substitute the ordered pairs to see which ones satisfies the equation.
For (-1,-8), we put x=-1 and y=-8 to get:
This is not true.
For 
we put x=-1 and 
to get
This is true
For (3,3/2) we have 2(3)+6(3/2)=15
This implies 6+9=15
15=15
This is also True
For (-5,25/6), we have 2(-5)+6(25/6)=-10+25=15
This is also true.
The length of the rectangle is 8cm longer than the width.
l=w+8
If the length of the original rectangle is increased by 6cm and the width is increased by 3cm the perimeter is 76cm.
p=76=((l+6)+(w+3))*2=(l+6+w+3)*2=(l+w+9)*2
to solve this substitute l=w+8 into the p= equation:
p=76=((w+8)+w+9)*2=
76=(2w+17)*2
76=4w+34
42=4w
10.5=w
l=w+8=10.5+8=18.5
