Ok
y=mx+b
b=yintercept
that's all you need to know

ok so we just list the yintercepts then order them
10,0.5,3,-5,7,-12
arrange from least to greatest
-12,-5,0.5,37,10

so the order of the functions is
y=-5x-12
y=0.5x-5
y=-4.5+3
y=-2x+7
y=2.5x+10

A box contains three plain pencils and 5 pens. A second box contains three colored pencils and three crayons. One item from each
worty [1.4K]

Answer:

Therefore the probability that a pen from the first box and a crayon from the second box are selected is \frac5{16}

Step-by-step explanation:

Probability:

The ratio of the number of favorable outcomes to the number all possible outcomes of the event.

Probability=\frac{\textrm{The number favorable outcomes}}{\textrm{The number all possible}}

Given that,

Three plain pencils and 5 pens are contained by the first box.

Total number of pens and pencils is =(3+5)=8

The probability that a pen is selected from the first box is

=P(A)

=\frac{\textrm{The number pens}}{\textrm{Total number of pens and pencils}}

=\frac{5}{8}

A second box contains three colored pencils and three crayons.

Total number of pencils and crayons is =(3+3)=6

The probability that a crayon is selected from the second box is

=P(B)

=\frac{\textrm{The number of crayon}}{\textrm{Total number of crayons and pencils}}

=\frac{3}{6}

Since both events are mutually independent.

The required probability is multiple of the events

Therefore the required probability is

=\frac58\times \frac36

=\frac5{16}

A fair coin is flipped 120 times. Estimate the expected number of ‘heads’.
Bumek [7]

when coin is flipped 5 times probability is 1/2

so coin heads comes out to be 2.5

This is a binomial distribution with a probability of success = 0.5 (fair coin).

n=10

so

mean = E[x] = np =10*0.5 =5
