Answer:
6/5
Step by step explanation:
Here we are provided with a equation which is ,
And we are interested in finding the slope of the line which is perpendicular to the given line. We may rewrite the equation as ,
Recall the slope intercept form of the line which is <u>y</u><u> </u><u>=</u><u> </u><u>mx</u><u> </u><u>+</u><u> </u><u>c</u><u> </u>.On comparing to which we get ,
Again , recall that product of slopes of two perpendicular lines is -1. So that ,
Hence ,
And we are done !
Answer:
The probability a random selected radish bunch weighs between 5 and 6.5 ounces is 0.8185
Step-by-step explanation:
The weight of the radish bunches is normally distributed with a mean of 6 ounces and a standard deviation of 0.5 ounces
Mean =
Standard deviation =
We are supposed to find the probability a random selected radish bunch weighs between 5 and 6.5 ounces i.e.P(5<x<6.5)
At x = 5
Z=-2
At x = 6.5
Z=1
Refer the z table for p value
P(5<x<6.5)=P(x<6.5)-P(x<5)=P(Z<1)-P(Z<-2)=0.8413-0.0228=0.8185
Hence the probability a random selected radish bunch weighs between 5 and 6.5 ounces is 0.8185
