Answer:
The store can be 90% confident that the interval from 0.293 to 0.355 captures the proportion of all customers of this store who have moved in the past 5 years.
Step-by-step explanation:
The confidence interval provides a range of values (lower and upper bound) based on a certain confidence level at which the true proportion or mean value of a given sample mean or proportion exists. In the scenario above, the confidence level is 90% and the confidence interval is 0.293 to 0.355. Hence, we can be 90% confident that the true proportion of all customers of the store who have moved within the last five years exists within this interval.
We know, the sum of all the angle in an triangle is 180,
So, We can calculate adjacent angle of angle 1,
Let, that adjacent angle = b
So, 34 + 103 + b = 180
b = 180 - 137
b = 43
Now, angle b forms linear pair with angle a, so their sum would be 180
a + b = 180
a + 43 = 180
a = 180 - 43
a = 137
In short, Your Answer would be Option C

here is your answer a good question
Answer:
A. 800 bacteria
B. 1.41 * 10^16 bacteria
Step-by-step explanation:
The model we have is
p(x) = 50 • 2^x
Doubling time is 30 minutes each
a. For 2 hours, we shall need to calculate the number of 30-minutes in 2 hours. That is 4
Thus the population after 2 hours would be
P(x) = 50 * 2^(4) = 50 * 16 = 800 bacteria
B. After one day
The number of hours in a day is 24;
since 60 minutes makes one day, the number of 30 minutes in a day would be 60/30 * 24 = 48
There are 48 30-minutes in a day
Thus the population of the bacteria after one day will be
P(x) = 50 * 2^48 = 1.41 * 10^16 bacteria
