Which situation shows dependent events?

A.
Raul rolled a number cube twice.

B.
Amelia tosses a coin and it shows tails. She tosses the coin again.

C.
Eric has a bag with 10 purple marbles and 7 blue marbles. Eric picks a marble, looks at the color, and puts the marble back into the bag. Eric picks a second marble.

D.
Ivy has a piggy bank with 7 one-dollar bills and 8 five-dollar bills. She reaches in and randomly pulls out a one-dollar bill. Without putting it back, she takes out another bill.

the answer is the option b

the range is all real numbers

step-by-step explanation:

we know that

the absolute value parent function is equal to

see the attached figure to better understand the problem

so

a. it is v-shaped > is true

b. the range is all real numbers > is not true

because the range is the > [0,∞)

all real numbers greater than or equal to zero

c. it goes through the origin > is true

d. the domain is all real numbers > is true

step-by-step explanation:

yeah i know the problem you need. i am taking it right now. the answer is step 3

answer-

the equation that models this pattern is

solution-

a researcher placed a petri dish with 32,000 bacterial cells. one hour after being placed in the vacuum chamber, the number of cells in the petri dish had halved. another hour later, the number of cells had again halved.

this can be represented as exponential decreasing function,

where,

putting the values,

y-intercept means, where x=0, so

the coordinate of this poin will be (0, 32000)

this means when x=0 or at the starting of the research, the number of bacteria cells was 32000.

after 3 hours, number of bacteria cells will be,

the   coordinate of this point will be (3, 4000)
