Answer:
$59.27
Step-by-step explanation:
It is exponential decrease.
After each year goes by its worth 100 - 0.13 = 0.87 of the previous value.
The equation of decrease is V = 90(0.87)^t where t = the number of years.
So after 3 years it is worth 90(0.87)^3
= $59.27.

Answer:
0.7611 = 76.11% probability that the weight of a randomly selected steer is less than 1140lbs.
Step-by-step explanation:
Problems of normally distributed samples can be solved using the z-score formula.
In a set with mean and standard deviation , the zscore of a measure X is given by:
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.
In this problem, we have that:
Find the probability that the weight of a randomly selected steer is less than 1140lbs.
This is the pvalue of Z when X = 1140. So
has a pvalue of 0.7611
0.7611 = 76.11% probability that the weight of a randomly selected steer is less than 1140lbs.
44 square feet
Diameter (4) divided by 2 is radius (2).
SA = 2πr^2 + 2πrh
SA = 2 * 3.14 * 2^2 + 2 * 3.14 * 2 * 3
SA = 2 * 3.14 * 4 + 2 * 3.14 * 2 * 3
SA = 6.28 * 4 + 6.28 * 3
SA = 25.12 + 18.84
SA = 43.96
Round to the nearest tenth.
SA = 44 square feet
