50% of babies are born female. Olive wants to find the probability that 20 or more of the 50 babies born today
were female.
We need to design a simulation. Which random device can we use to
BEST represent this situation?
Use a pair of dice and assign
doubles as female and
everything else as male.
Use a double-sided coin and
assign heads as females and
tails as males.
Use a random number generator
with the numbers 1 through 100
and assign 1 through 20 as
female and 21 through 100 as
male.
Use a spinner with 50 parts
and assign 20 parts as female
and 30 parts as male.

"image"

step-by-step explanation:

in most of these problems, the notation is that the point with a "prime" is the image of the point without. that is, b' is the image of b.

here, there is no dilation or reflection. there is simply translation (with no direction shown). which figure you call the "preimage" and which one you call the "image" is up to you. as a matter of convention, the naming is as described above.

0.0076, if you meant 4.125 divided by 0.03125 it would be 132

step-by-step explanation:

first you have to move the decimal in 0.03125 over until its behind the 5 which is 5 places over. now the number is 3125

then you have to move the decimal in 4.125, 5 places over. now the number is 4,112,500.

now you divide like you would normally would and get 0.0076
