Answer:
69.5%
Step-by-step explanation:
A feature of the normal distribution is that this is completely determined by its mean and standard deviation, therefore, if two normal curves have the same mean and standard deviation we can be sure that they are the same normal curve. Then, the probability of getting a value of the normally distributed variable between 6 and 8 is 0.695. In practice we can say that if we get a large sample of observations of the variable, then, the percentage of all possible observations of the variable that lie between 6 and 8 is 100(0.695)% = 69.5%.
Answer:
x=1/25
Step-by-step explanation:
Answer:
11196.15 km
Step-by-step explanation:
Consider the attached diagram
If the Airplane is at point A and the floating debris at point C, we want to determine the horizontal distance |AB| before they fly over it.
Using trigonometry
Cross multiply
|AB|X Tan 15 =3000
|AB| = 
=11196.15 km
Therefore, the horizontal distance |AB| before they fly over it is 11196.15 km
Answer:
0.22
Step-by-step explanation:
The point estimate is simply the middle of the confidence interval.
p = (0.195 + 0.245) / 2
p = 0.22
(a) m<IJK = 90 since segment IK is a diameter
(b) KI = 10 since since LM = KM = KI = 5. The 3 segments are radii.
(c) EP * PL = OP * PF; EP = 2
(d) m<OFH = 178/2 = 89; inscribed angle is half measure of intercepted arc
