PLEASE HURRY Janice rides the bus to school each day. She always
arrives at her bus stop on time, but her bus is late 80% of
the time.
Janice runs a simulation to model this using a random
number generator. She assigns these digits to the possible
outcomes:
• Let 0 and 1 = bus is on time
Let 2, 3, 4, 5, 6, 7, 8, and 9 = bus is late
The table shows the results of the simulation.

What is the estimated probability that Janice's bus will be late every day next
week?
A. 1 = 30%
B. b = 50%
c. 10 = 0%
D. 16 = 60%

hi! : )

a farmer that lived in ancient egypt would most likely be barried in the sand, in the desert!

: )

d. 24+-0.114

step-by-step explanation:

the question requires us to calculate the approximate 95% confidence interval for the mean number of ounces of ketchup per bottle in the sample given the following statistics;

sample mean = 24

standard deviation, σ = 0.4

sample size , n = 49

the confidence interval for a population mean is calculated using the formula;

sample mean ± z-score*(σ/sqrt(n))

the z-score associated with a 95% confidence interval, from the standard normal tables, is;

1.96

substituting these values into the formula;

24 ± 1.96*(0.4/7)

= 24 ± 0.112

from the alternatives given, choice d is closest to the above expression;

answer: translate the circles so they share a common center point and dilate circle y by a scale factor of 3.

we can't see all full 4 options, but if this is the full option, than the very left one is correct:

-2/5 * -3 3/4

remake the question, adding a picture of all the question, or write down the full left and right answers.
