Mama's Italian Restaurant has collected data about customer sauce orders. It calculated that P(marinara) = 0.82, P(alfredo) = 0.
wariber [46]
Denote by m for marinara and by a for alfredo and recall the following law:
P(M\cup A)=P(M)+P(A)-P(M\cap A)
Therefore 
P(M\cap A)=P(M)+P(A)-P(M\cup A)\\ 0.82+0.76-0.96\\ =0.62
The correct answer is the last one.

The area of a rectangle is represented by the polynomial 16x2  56x . The width of the rectangle is given by thebinomial 2x7. (
weqwewe [10]

Answer:

a) Length = 8x

b) Width = 27 units        

Step-by-step explanation:

We are given the following in the question:

Area of rectangle, A =

A = 16x^2 + 56x

Width of rectangle, w =

w = 2x + 7

a) Length of the rectangle.

Area of rectangle is given by:

A = l\times w

where l is the length of rectangle.

Putting values, we get,

16x^2 + 56x = a(2x+7)\\\\l = \dfrac{16x^2 + 56x}{2x + 7}\\\\l = \dfrac{8x(2x+7)}{2x+7}=8x

b) Width of rectangle

Length of rectangle = 80

8x = 80\\\Rightarrow x = 10

Thus, width of rectangle is

2x + 7\\=2(10) + 7= 27

Thus, the width of rectangle is 27 units.

Order from least to greatest: 2/3, 25%, 3/5, 0.40 and show work
enyata [817]
First, you will have to convert all of these numbers to decimals.
2/3=0.6 repeating 
25%=0.25
3/5=0.6
0.40 is already in the decimal form
Then, you order them.
25%, 0.40, 3/5, 2/3 (because the 6 is repeating. So basically 0.60 is smaller than 0.66 in case you are wondering)
