Based on a random sample of 1200 adults, a 95% confidence interval for the proportion of all adults who
regularly wear a wrist watch is (0.29, 0.35).
What is the point estimate for the proportion of all adults
who regularly wear a wrist watch based on these sample
results?
a 0.32
b It cannot be determined from the given information.
с 0.03
d 0.33

step-by-step explanation:

it works trust me

logv3(x+2)=1

rewrite in exponential form:

logb(x) = y is equal to b^y =x

b = 3, y = 1

now solve for x:

3^1 = x+2)

x = 3-2

x = 1

2.2°  

step-by-step explanation:

let θ = the angle of elevation.

tanθ =77/2020

tanθ = 0.038 12

      θ = tan⁻¹0.038 12

      θ = 2.2°

no
