5. Comparing Chances a) Suppose a coin is tossed repeatedly. Without any calculation other than obvious conversions between counts and percents, say which (if any) of the following chances is bigger. Explain your answer. the chance of getting between 40 and 60 heads (that is, 40 through 60) in 100 tosses the chance of getting between 400 and 600 heads in 1000 tosses

if x decreases by 4 then y increases by 10

step-by-step explanation:

x= -3 and

step-by-step explanation:

to find the roots of a cubic, use division or factoring to find the factors then set equal to 0. as this is a difference of cubes, it factors into

where a is the cube root of .

here   this is 27 and the cube root of 27 is 3. so we write using the form:

.

set each factor to 0 and solve for x.

x-3=0

x=3

the quadratic expression does not factor and must be solved using the quadratic formula.

where a = 1, b=3, and c=9

this cubic has two complex roots.

the answer is (-8,-5)

step-by-step explanation:

the endpoint to midpoint is half the length. the length is (-2,-1) so when you are at the midpoint just add it to it to find your answer -6+(-2)= -8 and -4+(-1)=-5 so (-8,-5)

he has now walked a total of what?

if i know what this is maybe i can
