Answer:
9.5
Step-by-step explanation:
1. Arrange in ascending order
4 5 6 7 8 9 10 11 12
2. Upper Quartile formula:
3×(N+1)÷4
3. Number of terms (N) = 9
4. Apply:
3×(9+1)/4
=3×10/4
=30/4
=7.5th term
5. 7.5th term is the average of the 7th and the 8th term so
Take average
7th term is 9 and 8th term is 10
6. Find average of 9 and 10 = 9.5
7. ANSWER : THE UPPER QUARTILE IS 9.5 FOR THE GIVEN DATA
Answer:
the correct answer is choice 2
Step-by-step explanation:
reason being that both bc and ac would both be vertical lines so they have the same slope of undefined
Check the picture below
use the far-arc near-arc equation
bear in mind, your far-arc and near-arc are both in y-terms, so, the angle will be in y-terms as well
Answer:
Null Hypothesis, H0 = The pulse rates of men have a standard deviation equal to 10 beats per minute
Alternate Hypothesis, H1 = The pulse rates of men do not have a standard deviation equal to 10 beats per minute
Step-by-step explanation:
The null hypothesis is basically the problem statement i.e
Pulse rates of men have a standard deviation equal to 10 beats per minute
Hence, H0 = The pulse rates of men have a standard deviation equal to 10 beats per minute
The alternate hypothesis will contradict or negate the null hypothesis i.e
H1 = The pulse rates of men do not have a standard deviation equal to 10 beats per minute
Answer:
x = 45/2 = 22.5 cm
Step-by-step explanation:
2x + 45 = 90
2x = 90- 45= 45
2x = 45
x = 45/2 = 22.5 cm
