Answer: No
Step-by-step explanation:
There is only one pair of congruent angles that can be determined, but to prove triangles similar, there needs to be two pairs of congruent angles.
Answer:
Mean = 13 kilometer per second
Standard Deviation = 0.4082 kilometer per second
Step-by-step explanation:
We are given the following data set of rocket speed in kilometer per second in the question:
12.7, 13.4, 12.6, 13.3
Formula:
where
are data points,
is the mean and n is the number of observations.
Deviations from mean = -0.3, 0.4, -0.4, 0.3
Sum of squares of differences =
0.09 + 0.16 + 0.16 + 0.09 = 0.5
![S.D = \sqrt{\dfrac{0.5}{3}} = 0.4082](https://tex.z-dn.net/?f=S.D%20%3D%20%5Csqrt%7B%5Cdfrac%7B0.5%7D%7B3%7D%7D%20%3D%200.4082)
Mean = 13 kilometer per second
Standard Deviation = 0.4082 kilometer per second
Answer:
The first equation is correct
Step-by-step explanation:
Three hundred and forty-one of one thousand
.8 (88%)+.2x=90%
70.4%+.2x=90%
subtract 70.4% from 90% to get 19.6%
make the .2x into 2 and the 19.6 into 196
divide 196 by 2 to come up with the answer of 98%.
you will need a 98% to have a 90% for the final grade
