NASA scientists obtained the following data from airborne radiometer scans using the ESTAR method of aperature synthesis Soil Mo

isture Percentages: 19,16,15,16.5,15,14 Source: D. M. LeVine, A. J. Griffis, C. T. Swift, and T. J. Jackson, "ESTAR: A Synthetic Aperature Microwave Radiometer for Remote Sensing Applications," Proceedings of the IEEE, December 1994, p. 1795 These data represent sample measurements taken over the 220-240 degree K brightness temperature range. The theoretical model states that the mean volumetric soil moisture percentage should be 13.5%. Use the confidence interval approach to conclude whether the sample data support or refute the null hypothesis that the mean ESTAR measurements equal the theoretical level, using a .05 level of significance. Lower 95% confidence limit Upper 95% confidence limit . What is your conclusion?

In a movie theater, the number of seats in a row is 8 greater than the total number of rows. How many rows are in the movie thea
Harman [31]

Answer:

26 rows

Step-by-step explanation:

this is like a rectangle length×width situation.

seats per row = s

number of rows = r

s × r = 884

s = r + 8

so, we can use e.g. the second equation in the first :

(r + 8) × r = 884

r² + 8r = 884

r² + 8r - 884 = 0

the general solution to such a quadratic equation is

x = (-b ± sqrt(b² - 4ac))/(2a)

in our case

x = r

a = 1

b = 8

c = -884

r = (-8 ± sqrt(8² - 4×1×-884))/(2×1) =

= (-8 ± sqrt(64 + 3536))/2 = (-8 ± sqrt(3600))/2 =

= (-8 ± 60)/2 = -4 ± 30

r1 = -4 + 30 = 26

r2 = -4 - 30 = -34

a negative number did not make any sense for the number of rows, so r = 26 is our answer.

Can I have help with 42?
Sphinxa [80]
#42.
14n - 32 = 22
add 32 to both sides
14n - 32 + 32 = 22 + 32
simplify
14n = 54
divide both sides by 14
14n/14 = 54/14
simplify
n = 3 12/14
n = 3 6/7 or n = 3.857
