Answer:
-1/3 is the slope perpendicular
Step-by-step explanation:
When we have 2 points, we can use the formula
m = (y2-y1)/(x2-x1) to find the slope
m = (1-7)/(3-5)
=-6/-2
=3
The slope is 3
We want a slope perpendicular
Remember that is the negative reciprocal
- (1/3)
-1/3

Answer:
And we can find this probability with this difference
And we can see the figure in the plot attached.
Step-by-step explanation:
Let X the random variable that represent the redings on thermometers of a population, and for this case we know the distribution for X is given by:
Where 
and 
We are interested on this probability
We can use the z score formula given by:
Using this formula we got:
And we can find this probability with this difference
And we can see the figure in the plot attached.
The area of the shaded region is 0.1271 (12.71%).
<h3>What is the
z score?</h3>
Z score is used to determine by how many standard deviations the raw score is above or below the mean. It is given by:
z = (raw score - mean)/standard deviation
Given:
Mean 0 and standard deviation 1. Hence, for z=-1.14:
P(z < -1.14) = 0.1271
The area of the shaded region is 0.1271 (12.71%).

Answer:
<h2><em><u>ᎪꪀsωꫀᏒ</u></em></h2>
➪40
Step-by-step explanation:
5x³+x²-2x
=> 5(2)³+(2)²-2(2)
=> 5(8)+4-4
=> 40
