to solve this system I first multiplied the second equation by 2 to make the x coefficient equal. then I subtracted equation two from equation one. this eleminated the x. solving for y gave me y=0. then I put 0 back in the original equation and that gave me x=-4.
The empirical rule says that roughly 99.7% of the population is within 3 standard deviations of the mean.
Start at the center 60 which is the mean. Add on 3 standard deviations
60 + 3*4.5 = 73.5
and subtract off 3 standard deviations from the mean
60 - 3*4.5 = 46.5
So roughly 99.7% of the population of cattle has horn lengths between 46.5 inches and 73.5 inches
<h3>Answer: Choice D. 46.5 in - 73.5 in</h3>
0.00373134328
I think you can round that but I think that's the answer.

Answer:
a = 1
Step-by-step explanation:
7*9 =
We can rewrite 9 as 10-1
7 * (10-1)
7 * 10 - 7*1
a = 1
