Answer:
The mammoth died 17.190 years ago.
Step-by-step explanation:
Given information:
- Half-life of C-14 is 5.700 years.
- Living elephant bones commonly contain about 40% C-14.
For every 5700 years, the elephant's bones losses a half-life of C-14. And supposing that the living mammoth bones had the same percentage of C-14.
If the mammoth when living has 40%, then:
- After 5.730 years, the mammoth bones will contain 20%.
- After 11.460 years(2 half-lives), the mammoth bones will contain 10%.
- After 17.190 years(3 half-lives), the mammoth bones will contain 5%.

Step-by-step explanation:
Given : Sample size of cars : n= 150, sample size is greater than 30 , so we use z-test.
Number of cars tested do have faulty catalytic converters =42
Then the proportion of cars have faulty catalytic converters : 
Critical value of z for 99% confidence level : 
Formula for Margin of error :
Hence, the required margin of error =

Step-by-step explanation:
Data
Rectangular ceiling
base = 63 ft
height = 60 ft
Formula
Area = base x height
Process
Area = 63 x 60
= 3780 m²
Hello!
If s(x) = x - 7 and t(x) = 4² - x + 3, find (t · s)(x) is also known as a composite function. (t · s)(x) is read as "t is composed of s", or "the composition of t and s".
(t · s)(x) = 4² -(x - 7) + 3
(t · s)(x) = 16 - x + 7 + 3
(t · s)(x) = -x + 16 + 7 + 3
(t · s)(x) = -x + 26
Therefore, (t · s)(x) = -x + 26.
