Answer:
range=u ± 3.09 sd
Step-by-step explanation:
Given:
mean, u= 26.8 mpg
standard deviation, sd=72 mpg
% contained in interval = 99.8%
the interval for 99.8% of the values of a normal distribution is given by
mean ± 3.09 standard deviation= u ± 3.09 sd
=26.8 ± 3.09(72)
=26.8 ± 222.48
= 249.28 , -195.68
range=u ± 3.09 sd = 249.28 , -195.68 !
Answer:
1.) 3.18
2.)3.375 (not rounded)
Step-by-step explanation:
To find the mean, you need to count the total value of the dots and divide that number by the amount of dots. For example: The value of the dots is 51, and the amount of dots is 16. So 51/16=3.18. This also applies to adding an extra dot in the 3's column. So 51+3=54. 54/17=3.176.
Answer:
82° ; 50° ; 52° ;domain error ;51° ; domain error
Step-by-step explanation:
Using a calculator :
sin(A) = 0.9903
A = sin^-1(0.9903) = 82.01 = 82°
6.) cos(A) = 0.6428
A = cos^-1(0.6428) = 49.99 = 50°
8.) tan(A) = 1.2851
A = tan^-1(1.2851) = 52.111 = 52°
9.) cos(A) = 1.2608
A = cos^-1(1.2608) = domain error
10.) sin(A) = 0.7777
A = sin^-1(0.777) = 50.98 = 51°
11.) sin(A) = 1.8330
A = sin^-1(1.8330) = domain error
