High school hurdling competition. He has a 10% chance of knocking
down a hurdle in one lap. He wants to know the probability of doing at least three laps before he
knocks a hurdle down. Which simulation can best be used to compute the probability?
A. Model D: Use a standard deck of cards. Randomly draw one card from the deck. After drawing
the card, place it back in the deck and shuffle. For one trial, draw a card from the deck three
times. Count the trial if only on the third draw, the card is an ace or a king of clubs. Repeat the
process for 200 trials.
B. Model C: Draw a tile from a bag containing ten different-colored tiles. For one trial, draw a tile,
with replacement, until the green tile is drawn. Count the trial if the green tile is drawn on the third
draw or later. Repeat the process for 200 trials.
C. Model B: Use a spinner with ten different colors of equal area. For one trial, spin the spinner
until it lands on pink. Count the trial if the spinner lands on pink on the second spin or later.
Repeat this process for 120 trials.
D. Model A: Draw a marble from a bag containing seven different colored marbles. For one trial,
draw the marbles, with replacement, until the green marble is drawn. Count the trial if the green
marble is drawn on the third draw or later. Repeat the process for 50 trials.

c: y > - 1/6x + 1

step-by-step explanation:

dashed line - meaning this < or > also not equal

solid line - meaning this < or > also equal

your answer is c because y > means up & it's shaded up, but y < means down

hope this ! : )

when functions are first introduced, you will probably have some simplistic "functions" and relations to deal with, usually being just sets of points. these won't be terribly useful or interesting functions and relations, but your text wants you to get the idea of what the domain and range of a function are. small sets of points are generally the simplest sorts of relations, so your book starts with those.

step-by-step explanation:

state the domain and range of the following relation. is the relation a function?

{(2, –3), (4, 6), (3, –1), (6, 6), (2, 3)}

the above list of points, being a relationship between certain x's and certain y's, is a relation. the domain is all the x-values, and the range is all the y-values. to give the domain and the range, i just list the values without duplication:

domain: {2, 3, 4, 6}

range: {–3, –1, 3, 6}

(it is customary to list these values in numerical order, but it is not required. sets are called "unordered lists", so you can list the numbers in any order you feel like. just don't duplicate: technically, repetitions are okay in sets, but most instructors would count off for this.)

while the given set does indeed represent a relation (because x's and y's are being related to each other), the set they gave me contains two points with the same x-value: (2, –3) and (2, 3). since x = 2 gives me two possible destinations (that is, two possible y-values), then this relation is not a function.

note that all i had to do to check whether the relation was a function was to look for duplicate x-values. if you find any duplicate x-values, then the different y-values mean that you do not have a function. remember: for a relation to be a function, each x-value has to go to one, and only one, y-value.

state the domain and range of the following relation. is the relation a function?

{(–3, 5), (–2, 5), (–1, 5), (0, 5), (1, 5), (2, 5)}

i'll just list the x-values for the domain and the y-values for the range:

60.9774

step-by-step explanation:

because when you add 47.6 plus 7.32 equals 54.92

and when you add .0574 + 6= 6.0574

and when you add 54.92 and 6.0574 you get the answer of 60.9774.

plzz mark brainlest last one got deleted. cause i didn't explain it but i did but i understand what the mod meant
