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>
Answer:
25/19
Step-by-step explanation:
100/76 we can divide both the numerator and denominator by 4 to get 25/19. The decimal answer would be around 1.32.
1 quarter is 191/200 inches......so 8 quarters is :
8 * 191/200 = 1528/200 = 7.64 inches long <==
(3,-4) is your x and y. Plug it in the equation so,
For x,
2x+3y=3
2x+3(-4)=3
2x-12=3
2x=12+3
2x=15
2x/2=15/2
x=7.5
For y,
2(3)+3y=3
6+3y=3
3y=-6+3
3y=-3
3y/3=-3/3
y= -1
