Answer:
A
The value is 
B
The value is 
Step-by-step explanation:
From the question we are told that
The population mean is 
The standard deviation is 
The sample size is n = 25
Generally the probability that a boy born full term in the US weighs less than 7 lbs is mathematically represented as
=> 
From the z table the area under the normal curve to the left corresponding to -0.6364 is
=>
Generally the standard error of mean is mathematically represented as
=> 
=> 
Generally the probability that the average weight of 25 baby boys born in a particular hospital have an average weight less than 7 lbs is mathematically represented as
=> 
From the z table the area under the normal curve to the left corresponding to -3.1818 is
=> 
=>
84!
All the sides are 18,24, and 30. Then the two triangles are 12.
Answer:
a. 129 meters
Step-by-step explanation:
The given parameters of the tree and the point <em>B</em> are;
The horizontal distance between the tree and point <em>B</em>, x = 125 meters
The angle of depression from the top of the tree to the point <em>B</em>, θ = 46°
Let <em>h</em> represent the height of the tree
The horizontal line at the top of the tree that forms the angle of depression with the line of sight from the top of the tree to the point <em>B</em> is parallel to the horizontal distance from the point <em>B</em> to the tree, therefore;
The angle of depression = The angle of elevation = 46°
By trigonometry, we have;
tan(θ) = h/x
∴ h = x × tan(θ)
Plugging in the values of the variables gives;
h = 125 × tan(46°) ≈ 129.44
The height of the tree, h ≈ 129 meters
