I need help ASAP!! Mike is a local farmer who is interested in how often residents in her town go to a farmer's market each month. She surveys 124 families and finds that, on average, those families visit a farmers' market 4.2 times
per month with a sample standard deviation of 1.3. If Mika wants to be 99% confident (z = 2.58) using this
sample, what should her margin of error be and what does it mean?

positive

step-by-step explanation:

the quadrant is facing upwards

answer: 8d

step-by-step explanation:

45+5= 50+5=55+5=60

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)
