Answer:

Step-by-step explanation:

The reference angle is given as 63 degrees. The sides in question, x and 1, are adjacent to and opposite of this angle, respectively. The trig ratio that utilizes the sides adjacent to and opposite of angles is the tangent ratio; namely:

tan(63)=\frac{1}{x} and rearrange algebraically to get

x=\frac{1}{tan(63)} to get

x = .5

A set of quiz scores is shown in the histogram below. The mean of the data set is 20.2, and the (population) standard deviation
Neko [114]

Answer:

13

Step-by-step explanation:

As the mean is 20.2 and the standard deviation is 2.4

The range within the first standard deviation is

(17.8,22.6)

This means that we can safely use the range of (18,22) as we cannot confirm whether the other values fall within the range.

Within this range there are

2+3+4+3+1=13

Three more than twice a number is less than negative thirteen. Solve the inequality for the unknown number.
Goshia [24]

Answer:

Step-by-step explanation:

The number = x

Three more than the number = x + 3

twice the number = 2x

which means:

           

          2x + 3 < -13

          2x + 3 -3 < -13 -3                 (subtract 3 from both sides)

          2x < -16

          2x/2 < -16/2                       (divide 2 from both sides)

          x < -8
