Answer:
Step-by-step explanation:
she had $ 24 to spend on 7 pencils....and after buying them she had $ 10.
this means that the total of the pencils was (24 - 10) = $14
and assuming each pencil cost the same price....
14/7 = $ 2 per pencil
or u can set it up as an equation
24 - 7x = 10....with x being the price of a pencil
24 - 10 = 7x
14 = 7x
14/7 = x
2 = x <==

The probability that the eruptions lasted between 1.14 min and 5.5 minutes is greater than 75%
Step-by-step explanation:
The explanation can be found in the attached picture. Chebyshev's <u>inequality </u>was used. It predicts the probability of the random variable to be in ( mean- K* standard dev< x < mean + K*standard dev).
Note: K must be greater than 1
