Use the probability distribution graph to answer the question.

Mathematics
1 answer:
vivado [14]3 years ago
7 0

Answer:

5

Step-by-step explanation:

So we want to find the value of x where the area to the left of it is equal to 0.6.

Let's start by finding the area of the first triangle, between x=0 and x=4.

A = 1/2 bh

A = 1/2 (4) (0.2)

A = 0.4

So we know a > 4.  What if we add the area of that rectangle?

A = 0.4 + bh

A = 0.4 + (1) (0.2)

A = 0.6

Aha!  So a = 5.

Help please! factoring polynomials
alexgriva [62]

Answer:

B

Step-by-step explanation:

you can use foil and the graph,

because you can see (in the graph) that the lines intersect at 1 and 4.

just use foil to help figure out which matches the slope.

something else (the normal way) is find which 2 numbers equal to the last coefficient, in this case it can be

-2 and -2,  2 and 2, 4 and 1 or -4 and -1, multiply them and if they make up the last coefficient, and added it equals the second coefficient it is correct.

lions [1.4K]

Answer:

2

Step-by-step explanation:

{n}^{ - 3}  =  \frac{1}{8}  \\  \\  {n}^{ - 3}  =  \frac{1}{ {2}^{3} }  \\  \\  {n}^{ - 3}  = {2}^{ - 3}.. (\because \frac{1}{a^n} = a^{-n}) \\  \\ n = 2 \\(\because exponents \: are \: same\: hence\: \\bases\: will \: also\: be\: equal)
