Answer:
A is true and B is false.
Step-by-step explanation:
x + 6.2 ≥ 10.9
Replace x for 4.7...
4.7 + 6.2 ≥ 10.9
10. ≥ 10.9 ( So this is true!)
x - 6.2 ≤ - 5
Replace x for 4.7...
4.7 - 6.2 ≤ -5
-1.2 is not ≤ -5 (So this is false!)
Answer:
The score is
Step-by-step explanation:
From the question we are told that
The population mean is
The standard deviation is
From the question we are told that the score follow a normal distribution
i.e
The proportion of score in the top 10% is mathematically
Where x is the minimum score required to be in the top 10%
Now the
So
So
So the critical value of 0.10 from the normal distribution table is
So
80 percent
Explanation:
Divide 60 by 75 and get the outcome of .80
Answer:
Side b = 10.2 m (1 d.p.)
Step-by-step explanation:
11² = 121
15² = 225
225 - 121 = 104
√104 = 10.2 (1 d.p.)
Side b = 10.2m
(Full answer = 10.198039)
11² + 10.2² = 15²
Answer:
I think the answer is b
