Answer:
3 1/2 pints
Step-by-step explanation:
A pint is two cups
7 cups / 2cups/pint = 7/2 pint = 3 1/2 pints
Binomial
Binomial distribution can be used because the situation satisfies all the following conditions:1. Number of trials is known and remains constant (n=10)2. Each trial is Bernoulli (i.e. exactly two possible outcomes) (defective/normal)3. Probability is known and remains constant throughout the trials (p=5%)4. All trials are random and independent of the others (assumed from context)The number of successes, x, is then given by
where
Substituting values, p=0.05, n=10, X=exactly 1
for X=1 (defective out of n)
P(X=1)=C(10,1)0.05^1*(1-0.05)^(10-1)
=10!/(1!9!)*0.05*0.95^9
=10*0.05*0.0630249
=0.315125 (to 6 places of decimal)
Based on the information given you create an image to guide you best. From there you need to remember that the reference angle is given (which is 40) since the length opposite to this angle is given (65 in height of Jessica) the length of the shadow is needed or the length adjacent to this angle. Therefore the rule of tangent is used and once all calculations are completed you get that the length of the shadow is 77 inches.
