Given:
A figure of a right triangle.
To find:
The missing side by using the trigonometric ratios.
Solution:
In a right angle triangle,

In triangle ABC,



Multiply both sides by 270.



Therefore, the missing side length is b=231.4 inches.
B. 5:10 because 15-5=10 which is the number of pencils with erasers and the 5 left are the amount of pencils which are missing an eraser
Answer:
Data is quantitative, data is categorical, data must be from a simple random sample, the data mut have normal distribution,
Step-by-step explanation:
When we make inference about one population proportion, we must ensure that the sample was taken randomly and observations follow a normal distribution. The sample size must be as large as possible with at least 10 counts of failures an 10 counts of successes. The individual observations must be independent. They must be quantified and categorized.
The standard form:

The point-slope form:

m - slope
(x₁, y₁) - point
The formula of a slope:

We have the points (2, -3) and (4, 2). Substitute:


<em>use distributive property</em>
<em>multiply both sides by 2</em>
<em>subtract 6 from both sides</em>
<em>subtract 5x from both sides</em>
<em>change the signs</em>

It would be B) 8x-10. You distribute the 5 to the (x-2) to get 5x-10 and then simplify the expression.
