Both (m + n)2<span> and 36 are </span>perfect<span> squares, and 12(m + n) is twice the product of (m + n) and 6. Since the middle term is positive, the pattern is (a + b)</span>2<span> = a</span>2<span> + 2ab + b</span>2. Place the x2<span> tile, 4 x-tiles and 4 1-tiles in the grid. Fill the outside sections of the grid with x-tiles and 1-tiles that complete the pattern.</span>

Step-by-step explanation:
The intersection of the graphs is at (-3,4).
Answer:
1. x = -4
y = -20
2. x = -1
y = 3
3. x = 7
y = 4
4. x = -6.5
y = -10.5

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.
