Write the equation of a line in - form that contains the point (- 1, - 2) and is perpendicular to the line y = 5x - 10 degrees
galina1969 [7]

Answer:

y+2= -1/5(x+1)

Step-by-step explanation:

if lines are perpendicular their slopes are negative reciprocal

y=mx+b where m is the slope

y=5x-10 has the slope 5 so a perpendicular line will have slope -1/5

equation point slope form

(y-y1) = m(x-x1) where m is slope, and (x1,y1) any point that belongs to the line

y+2= -1/5(x+1)

The mean lifetime of a tire is 46 months with a variance of 49. if 133 tires are sample, what is the probability that the mean o
nata0808 [166]
Answer: The correct probabilities is about 0.1192.

To start we need to find the standard deviation, it is the square root of the variance or 7.

Now, we need to find the z-score of a value that is 1.05 months above the mean.

1.05 / 7 = 0.15 produces a value of 0.5596. Since we are dealing with a range from 0.15 below and above the mean, we have 0.0596 to the right of the mean and the same below the mean.

0.0596 x 2 = 0.1192

Compute the critical value z Subscript alpha divided by 2 that corresponds to a 96​% level of confidence.
Katarina [22]

Complete Question

Compute the critical value  Z_{\frac{\alpha }{2} }   that corresponds to a  96​%  level of confidence.

Answer:

The value is  Z_{\frac{\alpha }{2} } = Z_{\frac{0.04}{2} }= 2.326

Step-by-step explanation:

From the question we are told that

    The confidence level C =  96\%

     

Generally the level of significance is mathematically represented as

      \alpha  = (100 -96)\%

      \alpha = 0.04

Now from the normal distribution table the critical value for \frac{\alpha }{2} is

    Z_{\frac{\alpha }{2} } = Z_{\frac{0.04}{2} }= 2.326
