Answer:

Step-by-step explanation:

When two angles add up to 90, they are complementary angles

∠a + ∠b = 90

59 + ∠b = 90

∠b = 90 - 59

∠b = 31°

The International Air Transport Association surveys business travelers to develop quality ratings for transatlantic gateway airp

yKpoI14uk [10]

Answer:

Confidence Interval in 95% confidence level for the quality rating is (6.06,7.46)

Step-by-step explanation:

Confidence Interval can be calculated using the formula M±ME where

M is the mean of the sample
ME is the margin of error in a given confidence level

Using the sample obtained from 50 business travelers we get

Mean of the sample is 6.76
standard deviation of the sample is 2.526

Margin of error (ME) around the mean using the formula

ME= $\frac{z*s}{\sqrt{N} }$ where

z is the corresponding statistic in 95% confidence level (1.96)

s is the standard deviation of the sample (2.526)

N is the sample size (50)

Using the numbers in the formula we get:

ME= $\frac{1.96*2.526}{\sqrt{50} }$ ≈ 0.70

Then the confidence interval becomes 6.76±0.70

The length of a rectangle is 6 meters more than its width. The area of the rectangle is 114 square meters. Which of the followin

Leno4ka [110]

Answer:

last one

Step-by-step explanation:

x = width

x+6 = length

Area = length times width

x(x + 6) = $x^{2}$ + 6x

$x^{2}$ + 6x = 114 (subtract 114 from both sides)

$x^{2}$ + 6x -114 = 0
