If a certain machine makes electrical resistors having a mean resistance of 40 ohms and a standard deviation of 2 ohms, what is
V125BC [204]

Answer:

The probability is  P(\= X  <  40.4) = 0.84134

Step-by-step explanation:

From the question we are told that

   The mean is  \mu =40 \ \Omega

   The standard deviation is  \sigma  = 2 \ \Omega

   The sample size is  n = 25

    The combined resistance is   \sum x_i = 1010 \ \Omega

Generally the sample mean is mathematically represented as

      \= x  = \frac{\sum x_i }{n}

=>   \= x  = \frac{1010 }{25}

=>   \= x  = 40.4 \ \Omega

Generally the standard error of the mean is mathematically represented as

     \sigma_{x} = \frac{\sigma }{\sqrt{n} }

=>  \sigma_{x} = \frac{ 2 }{\sqrt{25} }

=>  \sigma_{x} = 0.4

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

       P(\= X  <  40.4) = P( \frac{\= X - \mu }{\sigma_{x }} <  \frac{ 40.4 - 40 }{0.4}  )

\frac{\= X -\mu}{\sigma }  =  Z (The  \ standardized \  value\  of  \ \= X )

    P(\= X  <  40.4) = P( Z <  1 )

From the z table  the area under the normal curve to the left corresponding to  1 is

     P(\= X  <  40.4) = P( Z <  1 ) = 0.84134

     P(\= X  <  40.4) = 0.84134

Which line has the same slope as the lone passing through (-4,-1) and (-1,-7)
Julli [10]

Answer:

1) 6x+3y=5    

Step-by-step explanation:

1) First, find the slope of the line passing through (-4, -1) and (-1, -7). Use the slope formula m = \frac{y_2-y_1}{x_2-x_1}. Substitute the x and y values of the two points into the formula and solve:

m = \frac{(-7)-(-1)}{(-1)-(-4)} \\m = \frac{-7+1}{-1+4} \\m = \frac{-6}{3} \\m = -2

So, the slope is -2.

2) Now, identify the slopes of the lines in the options. We already know the slope of y = -\frac{1}{2} x-7  is -\frac{1}{2} since it is in slope-intercept form. y = -2 must have a slope of 0 since it's horizontal, and all equations with the format of y = a number are horizontal.

To find the slope of 6x + 3y = 5, isolate y to put the equations into slope-intercept form (y = mx + b format), and whatever the coefficient of the x-term is will be the slope.

6x + 3y = 5\\3y = -6x+5\\y = -2x + \frac{5}{3}.

So, the slope of the first option is -2. It matches the slope we calculated in the first step, so that must be the answer.

Write the equation of the line with a slope of -1/3 and passing through the point (6, -4).
Lina20 [59]
Y = -1/3x + b
then plug it in
-4 = (-1/3 x 6) + b. (6 times -1 divided by 3)
-4 = -2 + b. (move -2 to other side)
b = -2. (now put em all together)
y = -1/3x -2
