Answer:
slope = (4-(-3))/(-3-2)=7/-5=-
Step-by-step explanation:
582 because you can not round to make it 3 582.091 rounds to 582.1 and you cant round on to make the 2 to a 3. 5 or above give it a shove 4
250,000 x 0.05 = 12,500
5500 / 12500 = 0.44
0.44 x 100 = 44%
Answer:
The interval [32.6 cm, 45.8 cm]
Step-by-step explanation:
According with the <em>68–95–99.7 rule for the Normal distribution:</em> If is the mean of the distribution and s the standard deviation, around 68% of the data must fall in the interval
around 95% of the data must fall in the interval
around 99.7% of the data must fall in the interval
So, the range of lengths that covers almost all the data (99.7%) is the interval
[39.2 - 3*2.2, 39.2 + 3*2.2] = [32.6, 45.8]
<em>This means that if we measure the upper arm length of a male over 20 years old in the United States, the probability that the length is between 32.6 cm and 45.8 cm is 99.7%</em>
I believe she will be at the age of 14 if she is 3 years younger
