Answer:
Dont know how to exactly explain but
Step-by-step explanation:
Both triangles angle y is 85 i forgot the proof name
For normal distribution 95% lie in the range mean-2*standard deviation for lower bound and mean+2*standard deviation for upper bound.
Upper bound is 78+2*6=78+12=90
Lower bound is 78-2*6=78-12=66
B. 66 and 90
I dont even get the question
Answer:
<1=23
Step-by-step explanation:
If WXZ contains both <1 and <2, and <2 is 4 times <1, then we can set this up as x + 4x = 115
This is easily simplified to 5x = 115
Divide both sides by 5 and you will get x=23
Answer:
Triangle has three sides so u can dismiss 2nd easily
scalene triangle has 2 equal sides
so, 1st is the correct answer
