The perimeter is 16.2. Let me know if you need me to show you how I got this
Negative correlation refers to an inverse relationship between two variables. When one variable increases, the other decreases.
The variables are latitude and average temperature.
The explanatory variable is latitude and the response is the average temperature. Choice B.
As the latitude increases, the average temperature decreases. This is a strong negative correlation of between the two variables.
Answer:
4) Unbiased; 5) Biased
Step-by-step explanation:
4) states that the audience of the poll was "random" people meaning it's a good foundation of data as they weren't chosen for the employee noticing their specific affiliation with being overjoyed with the product (as the question doesn't say) or for not liking (have complaints about it) the product.
5) The audience of the poll is fans of a sports team--definitely biased because they'll say they love the 49ers being a fan for them. Leads to skewed results not representing a portion of a population accurately.
Step-by-step explanation:
remember, the sum of all angles in a triangle is always 180°.
and the sum of all angles around one point at one side of a line is also airways 180° (because you can imagine that point to be the center of a circle, and the line would cut that circle in half = 180° for every half).
in the triangle LKM we know 2 angles already :
angle 1 = 44°
angle K = 90° (right angle).
so, angle 2 = 180 - 90 - 44 = 46°
and so, angle 5 = 180 - 46 = 134°.
as the angles around point L on line KL are the angles 2 and 5.
angle 5 = 134°
