Let's solve ~
If it passes through x, then let's find x when y = 0
So, required values of x are 3 and -2
Now, let's differentiate the equation to get slope slope for tangent ~
Now, plug in the values of x to find slopes of tangents
and
We know, tangent are normal are perpendicular. so let's find out slopes of normals m1' and m2'
and
Now, write the equations of normals using point slope form :
Normal 1 : passing through (3 , 0), and slope = -1/5
and
Normal 2 : passing through (-2 , 0), and slope = 1/5
That's all for Aunty ~ hope it helps !

Answer:
a = g/c - r/c + d/c
Step-by-step explanation:
Isolate the variable by dividing each side by factors that don't contain the variable
Answer:
0.03 is the probability that for the sample mean IQ score is greater than 103.
Step-by-step explanation:
We are given the following information in the question:
Mean, μ = 100
Standard Deviation, σ = 16
Sample size, n = 100
We are given that the distribution of IQ score is a bell shaped distribution that is a normal distribution.
Formula:
Standard error due to sampling =
P( mean IQ score is greater than 103)
P(x > 103)
Calculation the value from standard normal z table, we have,
0.03 is the probability that for the sample mean IQ score is greater than 103.
