Answer: (x-12)^2-144
Step-by-step explanation:
use the formula (b/2)^2 in order to create a new term to complete the square.
LET ME KNOW IF ITS RIGHT
Answer:
x = 14
Step-by-step explanation:
you would first distribute the -2 with x - 2, which should give you -2x + 4, and you want to do the -3 - 21, which would give you -24, then subtract 4 from -2x + 4, then you should have -2x = -28, then divide it by -2, which should give you x = 14
Answer:
8
Step-by-step explanation:
401.92 divided by 16 = 25.12
25.12 divided by 3.14 is 8
Area = Length x Width
L = 2.25 m = 225 cm
W = 1.8 m = 180 cm
A = 225 * 180 = 40,500 cm²
Answer: Area of the blanket is 40,500 cm².
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.
