The sound intensity of rustling leaves, y = 20 decibels
<u>Step-by-step explanation:</u>
y = 10logx
The sound intensity of rustling leaves is 100 times the reference intensity.
x = ratio of intensity of sound to reference to intensity
x = 100:1 or x = 100
y = 10 log(100) = 10 * 2 = 20 decibels
y = 20 decibels

Answer:
The probability is 
Step-by-step explanation:
From the question we are told that
The mean is 
The standard deviation is 
The sample size is n = 25
The combined resistance is 
Generally the sample mean is mathematically represented as
=> 
=> 
Generally the standard error of the mean is mathematically represented as
=> 
=> 
Generally the probability that a random sample of 25 of these resistors will have a combined resistance of less than 1010 ohms is mathematically represented as
From the z table the area under the normal curve to the left corresponding to 1 is
Answer:
Step-by-step explanation:
The point slope form is expressed as
y - y1 = m(x - x1)
Where
m represents slope
Slope, m =change in value of y on the vertical axis / change in value of x on the horizontal axis
change in the value of y = y2 - y1
Change in value of x = x2 -x1
y2 = final value of y
y 1 = initial value of y
x2 = final value of x
x1 = initial value of x
The given points are (2,6) and (-1,3)
y2 = 3
y1 = 6
x2 = - 1
x1 = 2
Slope,m = (3 - 6)/(- 1 - 2) = - 3/- 3 = 1
To determine the equation, we would substitute x1 = 2, y1 = 6 and m= 1 into the point slope form equation. It becomes
y - 6 = x - 2
