Answer:
19.8 years old
Step-by-step explanation:
If Z=(x-μ)/σ where Z=-1.32, σ=3.2, and μ=24, then:
-1.32=(x-24)/3.2
-4.224=x-24
19.776=x
19.8
Therefore, the age of a concert attendee with a z-score of -1.32 is 19.8 years old.
Answer:
90.80
Step-by-step explanation:
6x+4
= (6)(13)+4
= 78+4
=82
3x
=(3)(13)
= 39
So we know the sides are 39 and 82
Pythagoras theorem in triangles
= a2+b2= c2
Now, we know the value of a and B but not c (the hypotenuse)
Therefore,
c2 = (39)^2 + (82)^2
= 1521+ 6724
= 8245
so, c = √8245
= 90.80 unitd
