The answer is 8 it should be
Alright in this one, you are going to need to factor.
The width is x
The length is 2x-4
To find the area of a rectangle is L*W
so (2x-4)(x) when distributed is 2x^2 -4x
Then put that in the equation and you have:
2x^2 -4x = 96
2x^2 -4x -96 = 0
2x^2+12x-16x-96=0
3x(x+4)-4(x+4)=0
(3x-4)=0
(x+4)=0
x=-4
<u>x=3/4</u>
Since length isn't negative
we will use <u>3/4 as x.
</u>
Width= 0.75 ft
Length= 1.5
Both have D as the correct answer.
Answer:
35%
Step-by-step explanation:
Data provided in the question:
P(Master card) = 27% = 0.27
P(American express card) = 19% = 0.19
P( Visa card ) = 22% = 0.22
P( Master and American express card ) = 9% = 0.09
P( Visa and master card ) = 14% = 0.14
P( American express and visa card ) = 6% = 0.06
Now,
The probability of selecting a family that has either a Visa card or an American Express card
= P( Visa card ) + P( American express card ) - P( Visa and American express card )
= 0.22 + 0.19 - 0.06
= 0.35
or
= 0.35 × 100% = 35%
