Draw a diagram
the diagram is a right triangle
use the tangent function
tan=opposite/adjacent
call the angle "θ"
tanθ=15/57
tanθ=0.2631579
use the arctan function on your calculator
tan-1θ=0.2631579
θ=14.74356312º or 14º 44' 36.827"
an equation is undefined, when its denominator is 0, or turns to 0, because we can't divide anything by 0.
so let's simply set the denominator of this one = 0.

A study done by researchers at a university concluded that 70% of all student-athletes in this country have been subjected to some form of hazing. The study is based on responses from 1800 athletes. What are the margin of error and 95% confidence interval for the study?
Answer:
Step-by-step explanation:
Given that:
The sample proportion
The sample size n = 1800
At 95% confidence interval level:
The level of significance = 1 - 0.95 = 0.05
Critical value:
Thus, the Margin of Error E =
the Margin of Error E = 0.021
At 95% C.I for the population proportion will be:
= 0.70 ± 0.021
= (0.70 - 0.021, 0.70 + 0.021)
= 0.679, 0.721)
Hello!

Answer:
D
Step-by-step explanation:
D is the only answer choice where the terms in the polynomials are descending in power, or their exponents. The powers are 7, 5, 4, 3, 0. The other answer choices have powers that aren't in descending order.
