Answer:
If you live to be 70, you will have spent 10 years of your life on Monday.
$7.75+$7.75=$15.50 (He took the taxi 2x)
$0.56(14)+$0.56(7)=$11.76 (14 miles on the way to work, 7 miles on the way home since he only rode half way and walked the other half)
$15.50+$11.76=$27.26
Ryan pays $27.76 for the taxi ride per day.
Missing sides or angles??
If it's missing sides... Then using sine rule
A/ sin A = B/ sin B
Let sin A =30° and A=8
Let sin B=60° and B =?
Hence 8/sin 30°=B/sin 60°
Multiplying 8 x sin 60 =B sin 60
6.928 = 0. 5B
Dividing both sides by 0.5
Hence B= 13.856
doing same for side c
Let sin A =30° and A =8
Let sin c =90° and C =?
Hence 8/sin30° = C/sin 90
Sin 90° x8 =. 0.5c
Sin 90=1
1x8 =0.5c
Dividing both sides by 0.5 gives 16
Hence C=16
Answer:
0.22
Step-by-step explanation:
Sample given is 500, so use z-score for the critical value
Given 95% confidence interval;
∝=100-95 =5% =0.05
∝/2 = 0.05/2 =0.025 ----because you are interested with one tail area
1-0.025= 0.975 -----area to the left
proceed to z-table to read 0.975 = 1.96 as the critical value
standard deviation from the question is 2.5 but because this is a sample then;
standard error for the mean is= standard deviation/√sample= 2.5/√500
=0.1118
Margin of error=1.96*0.1118 =0.2191
