Answer: 0.02
Step-by-step explanation:
Given: Sample size : 
The population proportion 
Then, 
The formula to calculate the standard error is given by :-
Hence, the standard deviation of the sample proportions (i.e., the standard error of the proportion) is <u>0.02</u>.
Answer:
I believe it is .0801
Step-by-step explanation:
- A negative exponent will always turn into a fraction
- First change it to a fraction
1/10^2
- Simplify the exponent
10 times 10 = 100
- Change the fraction
1/100 or in decimal form which is 0.01
- Now the addition
8 + 0.01 = <u>8.01</u>
- Move decimal to two decimal places
.0801
Answer:
x <= -2 or x >= 3
Step-by-step explanation:
Shaded circles represent <= or >=, and the first arrow points left from -2, and the second arrow points right from 3. Therefore x <= -2 or x >= 3 would represent the graph.
Answer:
5
Step-by-step explanation:
5 makes sense since the period of time this takes place is 5 days. therefore [?] should be 5
Answer:
Only option B is correct, i.e. all real values of x except x = 2.
Step-by-step explanation:
Given the functions are C(x) = 5/(x-2) and D(x) = (x+3)
Finding (C·D)(x) :-
(C·D)(x) = C(x) * D(x)
(C·D)(x) = 5/(x-2) * (x+3)
(C·D)(x) = 5(x+3) / (x-2)
(C·D)(x) = (5x+15) / (x-2)
Let y(x) = (C·D)(x) = (5x+15) / (x-2)
According to definition of functions, the rational functions are defined for all Real values except the one at which denominator is zero.
It means domain will be all Real values except (x-2)≠0 or x≠2.
Hence, only option B is correct, i.e. all real values of x except x = 2.
