So, we know that the internal angles of a triangle add up to 180 degrees, yes?
60 degrees plus 50 degrees equals 110 degrees, and subtract 110 from 180, and you get 70 degrees for angle y.
Now, if the triangles are congruent (identical) and the shape you are describing is like an hourglass, then because of the vertical angles theorem, angle x should be 70 degrees too!
Hope I helped!! :)
I did the test. The answer is "Group X has less variability in the data."
|2x+7| less than or equal to 27 is equal to -10 less than or equal to x less than or equal to 10. try writing it in a math form and you will get your answer.
Answer:
Probability distribution B
Step-by-step explanation:
Probabilities cannot be negative numbers. This means we can exclude distributions A and C.
Probability can be a maximum of 1.0. This means we can eliminate distribution D.
This leaves distribution B.
We can double check by finding the sum of the distribution. The sum of a probability distribution is 1.0. Adding these probabilities together, we have
0+0.45+0.16+0.39 = 1.00
B is correct.
