Answer:
x= -8 x=2
Step-by-step explanation:
x^2 +6x-6= 10
Subtract 10 from each side
x^2 +6x-6-10= 10-10
x^2 +6x-16 = 0
What 2 number multiply to -16 and add to 6
8 * -2 = -16
8 -2 = 6
(x+8) (x-2)=0
Using the zero product property
x+8=0 x-2=0
x= -8 x=2
Answer:
The probability that Joe will be accepted at one and only one university
P(A n B ) = 0.1
Step-by-step explanation:
Given data the acceptance rate for applicants with similar qualifications is 25% for University A
P(A) = 25% =0.25
The acceptance rate for applicants with similar qualifications is 40% for University B
P(B) = 40% =0.40
<u>Independent events:</u>
let E and F are said to be independent events then
P(E n F ) = P(E ) P(F)
both universities are independent
The probability that Joe will be accepted at one and only one university
P(A n B ) = P(A) P(B) = 0.25 X 0.40 = 0.1
The total amount would be 13/20 I believe I'm not too sure
Using a system of equations, it is found that the unit prices are:
- $2.25 for a bag of chips.
- $1.50 for a liter of pop.
- $1.75 for a chocolate bar.
For the system:
- x is the unit price of a bag of chips.
- y is the unit price of liter of pop.
- z is the unit price for a chocolate bar.
From the table, the equations are:



Replacing the <u>first equation on the second and the third:</u>









Since
:




Then:


The unit prices are:
- $2.25 for a bag of chips.
- $1.50 for a liter of pop.
- $1.75 for a chocolate bar.
