Pani-rosa [81]

Answer:

Mr Blake's science class

Step-by-step explanation:

The standard deviation is a measure of variation.

It tells us how far each of the data set in the distribution are far from the mean of the distribution.

The average score of students in Mr. Blake's science class was 73 with a standard deviation of 11, while the average score of students in Mrs. Arnold's class was 75 with a standard deviation of 10.

Since 11>10, Mr Blake's science class is more variable than Mrs. Arnold's class.

Type the correct answer in the box.<br><br><br> In this triangle cosA/cosB= blank
Elina [12.6K]

Answer:

1

Step-by-step explanation:

A triangle is a polygon with three sides and three angles. The types of triangles are scalene triangle, equilateral triangle, right angled triangle and obtuse triangle.  

Trigonometric functions are used to show the relationship between the angles of a triangles and the sides of the triangle. For a right angled triangle, the ratio of the sides can be gotten using trigonometric functions such as:

cosθ = adjacent/hypotenuse, sinθ = opposite/hypotenuse, tanθ = opposite/adjacent

Given the right angle triangle:

cos(A) = adjacent / hypotenuse = 3 / 4.24

cos(A) = 3 / 4.25

cos(B) = adjacent / hypotenuse = 3 / 4.24

cos(B) = 3 / 4.24

cos(A) / cos(B) = (3 / 4.24) ÷ (3 / 4.24) = 1

cos(A) / cos(B) = 1
