Answer:

99% Confidence interval: (1196,1973)

Step-by-step explanation:

We are given the following in the question:

Sample size, n = 20

Mean, μ = 1584

Standard Deviation, σ = 607

99% Confidence interval:

$\bar{x} \pm t_{critical}\displaystyle\frac{s}{\sqrt{n}}$

Putting the values, we get,

$t_{critical}\text{ at degree of freedom 19 and}~\alpha_{0.01} = \pm 2.86$

$1584 \pm 2.86(\dfrac{607}{\sqrt{20}} )\\\\ = 1584 \pm 388.18\\ = (1195.82 ,1972.18)\\ \approx (1196,1973)$

Thus, there is a 99% chance that it will break in approximately 1196 to 1972

Answer:

no, he will not.

Step-by-step explanation:

If he goes 140 miles in 2 hours, then in 6 hours he would go 420 miles. 420 miles is not equivalent to 490 miles, so he would not reach his destination on time.

An airplane flying at an altitude of 1000 feet spots a runway beacon 4000 feet away.What should the airplane’s angle of descent

eimsori [14]

tan(theta) = opposite side/adjacent side
So tan (theta) = 1000/4000= 1/4
so theta= arc tan(1/4)= 0.245 radians= 0.245*180/pi = 14degree
So option a is correct.
