Since you didn't give an amount of time, we can't give an exact value. However, I can help you with the steps so you can get the correct answer.

First, you need to find the correct z-score. Then, use a standard normal distribution table to find the percent.

Let the time that you are looking for equal X.

The formula for your z-score is:

(x - 8.7) / 2.1 = z-score

Staph the inequality and plot a point in the solution set. Explain how you know the point is a solution.

seropon [69]

Answer:

The points when graphed are: (3,0) and (0,-5)

Step-by-step explanation:

I know that these points are a solution to the graph because it has one x value and one y value that stays constant.

For an example, if we used an X and Y table we could see that each variable has one other variable.

This is how it look like when graphed:

Suppose 0 is an angle in the first quadrant and cos(0) = 1 What is the value of sin(0)?

suter [353]

Answer:

Step-by-step explanation:

I'm going to use a Pythagorean identity to help make this make sense.

$sin^2\theta+cos^2\theta=1$

We are given that cos(0) = 1, so

cos²θ = 1² which simplifies to

cos²θ = 1. So filling into our trig identity:

sin²θ + 1 = 1 and

sin²θ = 0 then

sinθ = √0 so

sinθ = 0

$sin^{-1}\theta=0$ so

sin(0) = 0

What is the lower quartile of the data? 16, 18, 59, 75, 30, 34, 25, 49, 27, 16, 21, 58, 71, 19, 50

svetlana [45]

Answer:

19.

Step-by-step explanation:

First arrange in ascending order:

16, 16, 18, 19, 21, 25, 27, 30, 34, 49, 50, 58, 59, 71, 75.

There are a total of 15 numbers, so the median is the 8th number = 30.

The lower quartile is halfway alone the first 7 numbers which is the 4th number and it is 19.

The median which is the middle number
