The probability of selecting a respondent who does not prefer Cell C is 0.775
<h3>How to determine the probability?</h3>
The complete question is in the attached image
From the attachment, we have
Prefer cell C = 90
Total = 400
So, the number of respondents that do not prefer cell C is
Do not = 400 - 90
Do not = 310
The probability is then calculated as:
P = 310/400
Evaluate
P = 0.775
Hence, the probability of selecting a respondent who does not prefer Cell C is 0.775

Answer:
Step-by-step explanation:
1. Two points are (2, 0) and (0, -2)
Slope of a line can be found from two given points.
Y-intercept is (0, -2)
m is slope and b is y-intercept
2. Slope of a line can be found from two given points.
Y-intercept is (0, 5)
m is slope and b is y-intercept
4 over 5 is greater than 2 over 3
(or)
4/5>2/3
Answer:
width = 5 ft
length = 9 ft
Step-by-step explanation:
Here, we want to get the length and width of the garden
length is 1 ft less than twice the width
if width = w
length = 2w-1
The product of the two is 45
so, we have it that;
w(2w-1) = 45
2w^2 - w = 45
2w^2 - w -45 = 0
2w^2 - 10w + 9w -45 = 0
2w(w-5) + 9(w-5) = 0
(2w + 9)(w-5) = 0
2w + 9 = 0
or w -5 = 0
w = 5 or-9/2
w cannot be negative, so we = 5
l = 2(5) -1 = 10 - 1 = 9 ft
