Answer:
the plane was 2500 meters
Step-by-step explanation:
the time/second on the graph show the number 1200 following the blue line it is in between 2000 and 3000
hope this answer your question good luck
Step-by-step explanation:
sum of the ratio=3+3+4=10
now,
angle I = 3/10×180=54
angle II= 3/10×180=54
angle III=4/10×180=72
that shows th given triangle is isoceles
Answer:
0.0403
Step-by-step explanation:
Given that 76% of americans prefer coke to pepsi.
Let x be the number of people who prefers coke to pepsi.
X is binomial as each trial is independent, and there are only two outcomes.
A sample of 27 was taken.
We have to find the probability that less than sixty percent of the sample prefers coke to pepsi
60% of 27 = ![27(0.6) = 16.2](https://tex.z-dn.net/?f=27%280.6%29%20%3D%2016.2)
Required probability = ![P(X](https://tex.z-dn.net/?f=P%28X%3C16.2%29%20%5C%5C%3DP%28X%5Cleq%2016%29%5C%5C%5CSigma%5E16_%7Br%3D0%7D%2027Cr%280.76%29%5Er%20%280.24%29%5E%7B27-r%7D)
Hence prob=0.0403
Image below, rotation for point (5,-2) gives you (2,5).
The discriminant is-
b^2-4ac=64-64=0
as the discriminant is 0, one solution will be -b/2a = -1/2
But still, we can't say that it has only one solution due to the nature of quadratic equations(It's tendency to have two solutions).
But we can say that both solutions are coincident.
Hence it has two solutions.
