Answer:
P = 0.688
Step-by-step explanation:
Since x= 1764, n = 2565
95%. CI= ( 0.670, 0.706)
a) P= x/n
P = 1764/2565
P = 0.688
Answer:
28
Step-by-step explanation:
1) subtract 12 from both sides
2) divide by negative 1
That's correct.
She will need to travel 244 miles a week for 9 weeks.
From the right triangle given, to obtain the unknown value we use the Trigonometry:
s/t
tan B=b/a
where:
B=15°
b=9
thus the value of a will be:
tan 15=9/a
solving for a we get:
a=9/tan 15
a=33.588~33.59
