Answer:
LCL = 59.26 to two decimal places
Step-by-step explanation:
Here, we want to estimate the LCL of the population mean with 90% confidence
We proceed as follows;
Given alpha = 0.1, then Z(0.05)=1.645 (from standard normal table), s = 15
Mathematically;
LCL =x_bar -Z*s/√( n)= 62 - (1.645 * 15)/√81
LCL = 62- (24.675)/9 = 59.2583
LCL = 59.26 to two decimal places
Given the equation:

Let's identify the type of polar graph for the equation.
To identify the type of polar graph, use the formula below to get the Cartesian form:

Thus, we have:
![(x^2+y^2)=3\sqrt[]{x^2+y^2}-5x](https://tex.z-dn.net/?f=%28x%5E2%2By%5E2%29%3D3%5Csqrt%5B%5D%7Bx%5E2%2By%5E2%7D-5x)
We have the graph of the equation below:
We can see the graph forms a Limacon with an inner loop.
Therefore, the type of polar graph for the given equation is a limacon with inner loop.
ANSWER:
N+-6=11 Write the original equation.
+6 +6 Add 6 to both sides.
N=17 This is the answer.
