Answer:
confidence interval =(0.10,0.16)
Step-by-step explanation:
Given that sample proportion was
26/200 =0.13 for a sample size of 200
Margin of error is given as 0.03
We know that confidence interval is one which is calculated as sample proportion ±Margin of error
Here sample proportion=0.13
Margin of error = 0.03
Hence
confidence interval lower limit = 0.13-0.03 = 0.10
Confidence interval upper limit = 0.13+0.03 = 0.16
Hence confidence interval =(0.10,0.16)
<u>Option A)</u> when y=6 and w= 2, <u>Option B)</u> when y=4 and w=-1 are the TWO correct choices.
Step-by-step explanation:
The given inequality is w<x<y and x>2.
<u>step 1</u>: let us <u>assume that x=3</u>, since it is given that x>2.
<u>step 2</u>: substitute the value of x=3 and each options in the inequality
<u>step 3</u>: option A) w=2, y=6. Then w<x<y = 2<3<6 (the condition satisfies).
option B) w= -1, y=4. Then w<x<y = -1<3<4 (the condition satisfies).
option C) w= 0, y=2. then w<x<y ≠ 0<2<2 (does not satisfies).
option D) w= -2, y=0. then w<x<y ≠ -2<2<0 (does not satisfies).
option E) w= -4, y= -1. then w<x<y ≠ -4<2<-1 (does not satisfies).
Answer:
The number in scientific notation is
Step-by-step explanation:
Given : The approximate distance between our solar system and Alpha Centaur (the nearest star) is 25,000,000,000,000 miles.
To find : Express the number in scientific notation ?
Solution :
The scientific notation is defines ad writing a number into smaller way or writing in terms of powers of 10.
Number - 25,000,000,000,000
It has already 12 zeros and add one zero to place a decimal,
Therefore, the number in scientific notation is
The answer is A !!! Good luck!
