75 I think since 75 divided by 3 equals 25

= <span>

From there you can cross multiply to get rid of the denominators.
4e=2x20
4e=40
e=10
There would be 10 ears.

Answer:
0.9466 = 94.66% probability that the weight of a randomly selected steer is between 639 and 1420lbs.
Step-by-step explanation:
Problems of normally distributed samples are 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 between 639 and 1420lbs.
This is the pvalue of Z when X = 1420 subtracted by the pvalue of Z when X = 639. So
X = 1420



has a pvalue of 0.9821
X = 639



has a pvalue of 0.0355
0.9821 - 0.0355 = 0.9466
0.9466 = 94.66% probability that the weight of a randomly selected steer is between 639 and 1420lbs.
Answer:
8
Step-by-step explanation:
Let the width of the rectangle be x. Then the length would be x+2
Area=(length)*(width)
48=x(x+2), => x=6. Width is 6 and length is 8
