The probability that a data value is between 54 and 66 is 81.9%
z score is used to determine by how many standard deviations the raw score is above or below the mean.
The z score is given by:
Given that μ = 62, σ = 4
For x = 54:
For x = 66:
P(54 < x < 66) = P(-2 < z < 1) = P(z < 1) - P(z < -2) = 0.8413 - 0.0228 = 81.9%
The probability that a data value is between 54 and 66 is 81.9%

The slope can be found using rise over run
the line goes up 5 and over 10
so the slope would be 5/10 or 1/2
therefore the equation of the line is:
y=1/2x
Answer:
23/35
Step-by-step explanation:
Probability ratio will be expresses with denominators of 12+7+16=35
Probability of selecting carmel is 12/35
Probability of selecting mints is 7/35=1/5
Probability of selecting chocolates is 16/35
Probability of not selecting a carmel will be given by 1-probability of selecting a carmel since maximum probability is always 1 or 100%
Probability of not selecting a camel will be 1-12/35=35/35-12/35=23/35
Alternatively, the probability of not selecting a carmel is equivalent to the sum of probability of either selecting a dark chocolate or mint which will be 7/35+16/35=23/35
The answers are the same, 23/35
