Answer:
C: x=-10
Step-by-step explanation:
Alternate interior angles are congruent to each other meaning that x+80=70 making x equal to -10. I hope this helped and this is one of my favorite units so post more these questions :)
Answer:
Given expressions are equivalent.
Step-by-step explanation:
Given expression:
4 (x + 3) + 2x and 6 (x + 2)
Find:
Given equivalent expressions or not
Computation:
By taking LHS
4 (x + 3) + 2x
4x + 12 + 2x
6x + 12
By taking RHS
6 (x + 2)
6x + 12
We say that
LHS = RHS
So,
Given expressions are equivalent.

Step-by-step explanation:
Answer: 0.16
Step-by-step explanation:
Given that the run times provided are normally distributed ;
Mean(x) of distribution = 3 hours 50 minutes
Standard deviation(s) = 30 minutes
The probability that a randomly selected runner has a time less than or equal to 3 hours 20 minutes
3 hours 20 minutes = (3 hrs 50 mins - 30 mins):
This is equivalent to :
[mean(x) - 1 standard deviation]
z 1 standard deviation within the mean = 0.84
z, 1 standard deviation outside the mean equals:
P(1 - z value , 1standard deviation within the mean)
1 - 0.8413 = 0.1587
= 0.16
