Answer:

D) plausible values that a parameter could take

Step-by-step explanation:

Confidence interval is estimated range of values for a population parameter could take in a given <em>confidence level</em>.

It can be represented as M±ME where

  • M is the point of estimate
  • ME is the margin of error

Confidence Intervals is measured to deal with <em>uncertainty</em>. For example, 95% confidence interval for a population mean is (25, 35) means that there is 95% chance that population mean is between the values 25 and 35.

If perimeter is 60 so the side is 60 ÷ 3 = 20

Now we can apply the area formula for triangles;

A=\frac{1}{2}.b.h\\&#10;\\&#10;A=\frac{1}{2}.20.17.3=10.17.3=173 \ cm^2

Convert r=53sinθ−cosθ to rectangular form.
Helga [31]

Answer:

y = \frac{1}{3} x + \frac{5}{3}

Step-by-step explanation:

r = 5/(3sinθ-cosθ)

multiply both sides by (3sinθ-cosθ):

r(3sinθ-cosθ) = 5

expand:

3rsinθ-rcosθ = 5

replace rsinθ with y and rcosθ with x:

3y-x = 5

add x to both sides:

3y = x + 5

divide both sides by 3:

y = 1/3x + 5/3
