Answer:
16000 bacteria after 60 days
Step-by-step explanation:
60 divided by 12 = 5
500 x 2= 1000
1000 x 2 = 2000
2000 x 2 = 4000
4000 x 2 = 8000
8000 x 2 = 16000
Answer: 1
Step-by-step explanation:
Gcf of 3 : 1 * 3
Gcf of 12184 : 1 * 12184
2 * 6092
4 * 3046
8 * 1523 .......
Gcf of 1545: 1 * 1545
3 * 515
5 * 309
All the the numbers do not have any common number except 1 so therefore 1 is the only common number which makes It the GCF in all three numbers.
Answer:
28.8 ft
Step-by-step explanation:
SOH CAH TOA reminds you that ...
Tan = Opposite/Adjacent
The height to the top of the antenna is opposite the angle of elevation, and the distance to the building is adjacent. So, we have ...
tan(58°) = (160 ft +antenna height)/(118 ft)
(118 ft)·tan(58°) = 160 ft + antenna height . . . . . . . multiply by 118 ft
188.8 ft - 160 ft = antenna height = 28.8 ft . . . . . . subtract 160 ft, evaluate
The height of the antenna is 28.8 ft above the top of the building. (The total height of building + antenna is 188.8 ft.)
Y = 5x - 1...so we sub 5x - 1 in for y in the other equation
-15x - 3y = 3
-15x - 3(5x - 1) = 3
-15x - 15x + 3 = 3
-30x = 3 - 3
-30x = 0
x = 0
y = 5x - 1
y = 5(0) - 1
y = -1
it has one solution (0,-1) <=
Answer:
The confidence level of the study is 99.9%
The confidence level is 99.9% of the margin error is 8%
Step-by-step explanation:
<u>Explanation</u>:-
Candy has observed 250 sports cars
The sample size 'n' = 250
Sample proportion 'p' = 15% = 0.15
The margin of error = 8% = 0.08
<em>The margin of error is determined by </em><em> = </em><em />
<em> </em><em />
<u>Conclusion</u>:-
The z- score of 99.9% level of significance = 3.54 for two tailed test
<em>Hence the confidence level is 99.9% of the margin error is 8%.</em>
