Answer:
Hence the best estimate is population with correct option is 74% and
the value for x=148
Step-by-step explanation:
Given:
A sample of 200
Of which 148 prefer brand new coffee
To Find:
Which statement is true?
Solution:
n=200
x=148
remaining 52 prefer old ones .
So estimate population proportion,
p=x/n
p=148/200
p=0.74
p=74 %
Now, when x=52
p=x/n,
p=52/200
p=0.26
p=26%
There is no option for 52 and 24 %
Hence x=148 and p=74%.
Answer:
P(t) = 27000 * (1/9)^(t/4)
Step-by-step explanation:
This problem can me modelled with an exponencial formula:
P = Po * (1+r)^t
Where P is the final value, Po is the inicial value, r is the rate and t is the amount of time.
In this problem, we have that the inicial population/value is 27000, the rate is -8/9 (negative because the population decays), and the time t is in months, so as the rate is for every 4 months, we use the value (t/4) in the exponencial.
So, our function will be:
P(t) = 27000 * (1-8/9)^(t/4)
P(t) = 27000 * (1/9)^(t/4)

Answer:
1 < x < 29
Step-by-step explanation:
The triangle inequality requires the sum of the two shortest sides exceed the longest side.
<u>When x and 14 are the shortest</u>:
x + 14 > 15
x > 1
<u>When 14 and 15 are the shortest</u>:
14 +15 > x
29 > x
Then the requirement for the length of x is ...
1 < x < 29
_____
<em>Additional comment</em>
The length of the third side of a triangle can be between the difference and sum of the two given sides.
