Answer:
95% confidence interval for the population mean is 20.255 and 17.945
Step-by-step explanation:
given data
mean = 19.1
standard deviation = 1.5
n = 9
to find out
95% confidence interval for the population mean
solution
we know 95% confidence interval formula i.e.
mean +/- t * standard deviation/
.............1
here t for 9 students 2.31 ( from t table)
so put all value n t standard deviation and mean in equation 1
= mean +/- t * standard deviation/
= 19.1 +/- 2.31 * 1.5/
= 19.1 +/- 2.31 * 1.5/
= 20.255 and 17.945
95% confidence interval for the population mean is 20.255 and 17.945
Answer:
The greatest common factor is 1
Step-by-step explanation:
The factors of 4 are: 1, 2, 4
The factors of 6 are: 1, 2, 3, 6
The factors of 45 are: 1, 3, 5, 9, 15, 45
Then the greatest common factor is 1.
(5,7) because when you divide that’s the answer you get
According to "Black Hole Beginnings," the destruction of some stars results in an an intense gravitational pull.
To answer the question, we need to know what Black Holes are.
<h3>What are Black Holes?</h3>
Blackholes are regions of space in which no matter can escape
<h3>Characteristics of black holes</h3>
- Black holes are formed from the remnants of large star that dies in a supernova
- As long as the star is three times or more larger than the sun, it will collapse
- The gravitational force on the star causes it to collapse into a black hole
So, when black holes are formed, some stars are destroyed and collapse due to intense gravitational forces.
So, according to "Black Hole Beginnings," the destruction of some stars results in an an intense gravitational pull.
