Answer:
The value of x is 
Step-by-step explanation:
From the question we are told that
The length of the vertical length is 
The length of the base leg is L = 330 + d units
The length of the bisecting line segment is h
The base angle is 
The angle between d and line segment is 
For the first angle

=> 
For the whole big triangle

=> 
So equating the both d

Substitute values




Answer:
The 99% confidence interval for the mean peak power after training is [299.4, 330.6]

Step-by-step explanation:
We have to construct a 99% confidence interval for the mean.
A sample of n=7 males is taken. We know the sample mean = 315 watts and the sample standard deviation = 16 watts.
For a 99% confidence interval, the value of z is z=2.58.
We can calculate the confidence interval as:

The 99% confidence interval for the mean peak power after training is [299.4, 330.6]
Answer:
This idea of reflection correlating with a mirror image is similar in math.
This complete guide to reflecting over the x axis and reflecting over the y axis will provide a step-by-step tutorial on how to perform these translations.
First, let’s start with a reflection geometry definition
Math Definition: Reflection Over the X Axis
A reflection of a point, a line, or a figure in the X axis involved reflecting the image over the x axis to create a mirror image. In this case, the x axis would be called the axis of reflection.
Math Definition: Reflection Over the Y Axis
A reflection of a point, a line, or a figure in the Y axis involved reflecting the image over the Y axis to create a mirror image. In this case, theY axis would be called the axis of reflection.
What is the rule for a reflection across the X axis?
The rule for reflecting over the X axis is to negate the value of the y-coordinate of each point, but leave the x-value the same.
Answer:
18.0
Step-by-step explanation:
Note the tenth place value (underlined and bolded): 18.<u>0</u>49
Look at the number to the direct right of the tenth place value (or the hundredth place value in this case). It is a 4.
Note the rules of rounding. If the number:
1) is 5 or greater, round up.
2) is 4 or less, round down.
In this case, it is 4, so you will round down.
18.049 rounded to the nearest tenth is 18.0
