Answer:
54 R 53
54 53/83
Step-by-step explanation:
4535 divided by 83 equals
54 with a remainder of 53
What sample size is needed so that the length of the interval is $60 with 95% confidence? We Assume: σ = $150.
Showing Work:
n ======> is the sample size we want to find:
N = ( z a/2^σ / E )^2
= ( 1.96 * 150 / 30 )^2 (margin of error is 1.96 times the standard error):
Answer: =======> 96.04 ≈ 97
Hope that helps!!!! : )
Option B:
BC = 49 feet
Solution:
Given m∠A = 130°,
AB = c = 30 feet
AC = b = 24 feet
BC = a = ?
Law of cosines:
Substitute the given values in the formula.
Taking square root on both sides, we get
a = 48.96
a = 49 feet
BC = 49 feet
Option B is the correct answer.
the problem would be set up as 6+(7*x)=41
first u take off the number 6 by subtracting it from itself to cancel it out then u do the same to the number 41
7x =41 now u need to cancel out the number 7 attatched to the x so u divikde it by itself and then do the same to the other side so 41 divided by 7 =5.9
so x =5.9
