No matter what, if you get at least 2 pair of flip flops you will be spending $8.50. So that's the amount you're going to spend plus 3.75 per pair after that. If she has $34.75 to spend and cannot go over, the inequality sign will be less than or equal to. It's ok if she spends less than that and it's ok if she spends exactly that, but she cannot spend more than she has. The inequality then would be this:
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!!!! : )
Answer: the value of x is 15°
Step-by-step explanation:
A is 2x. B is 2(2x), so 4x. C is 3(2x) so 6x.
The sum of all the angles of a triangle is 180°
Set up the equation:
2x + 4x + 6x = 180
12x = 180°
x = 15°
