Answer:

5/11

Step-by-step explanation:

probability = # of favorable outcomes / # of total outcomes

favorable outcome = selecting a pair of formal shoes.

There are 5 pairs of formal shoes so # of favorable outcomes = 5

The total number of outcomes = sum of different pairs of shoes. There are  5 pairs of formal shoes, 2 pairs of traditional shoes, and 4 pairs of casual shoes, so total there are 5 + 2 + 4 = 11 pairs of shoes

so we have probability =  # of favorable outcomes / # of total outcomes

and # of favorable outcomes = 5 and total # of outcomes = 11 so probability of selecting a pair of formal shoes is 5/11

A polynomial is factored using algebra tiles
dezoksy [38]

Answer:

A) x^2-2x-8

Step-by-step explanation:

The polynomial factored is equal to the area of the algebra tiles. This means the quadratic is

x^2 + x+ x -x -x -x -x-1-1-1-1-1-1-1-1\\x^2-2x-8

After writing out each tile as a term, combine like terms to simplify. This ia the quadratic.

x^2-2x-8

Which fractions are equivalent to 15/20
Digiron [165]

Answer:

\frac{3}{4}, \frac{30}{40}, \frac{45}{60}, \frac{60}{80}....e.t.c are all equivalent fractions

Step-by-step explanation:

For the answer you need to know bout equivalent fractions

TO find equivalent fractions you have to multiply the numerator and denominator by the same amount

E.x.\frac{15}{20}=\frac{(15)(2)}{(20)(2)} =\frac{30}{40}

Therefore \frac{30}{40} is an equivalent fraction

What is P(4 ≤ X ≤ 6)? Explain. <br> If P(X ≤ a) = 0.2, what is a? Explain.
melamori03 [73]

Answer:

(a) 0.4

(b) a = 3

Step-by-step explanation:

(a) The area under the curve from x=4 to x=6 is 0.2 units high and 2 units wide, so is 0.2·2 = 0.4. (The area of a rectangle is the product of length and width.)

(b) The area is 0.2 and the height of the curve is 0.2, so the width of the region of concern is 0.2/0.2 = 1. (Again, area = height·width, or width = area/height.) 1 unit from the left end is found at X=3, so a = 3.
