Answer:
67.88°
Step-by-step explanation:
If three sides of a triangle are known and you want to determine one angle, this can be done using cosine rule.
Given sides x, y, and z and the angle Y is opposite to side y, the cosine formula is given as:
y² = x² + z² - 2xzcosY
For this problem, x = 400 miles, y = 599 miles, z = 320 miles.
Using the cosine formula:

Degree to adjust its route at point Y = 180° - 112.12° = 67.88°
It needs to adjust by 67.88° at point Y
From the problem, we have the following given
u = 5
x = 0
We use the Poisson distribution probability formula:
P = (e^-μ) (μ^x<span>) / x!
Substituting
P = (e^-5) (5^0) / 0!
P = 0.0067

The probability is 0.0067 or 0.67%<span />
No. The new area is 2.25 times the original area. That's (1.5 times 1.5).
Answer:
6, 5
Step-by-step explanation:
-3 + 9 = 6
15-10 = 5
4.5 thats the answer. Im just typing so its long enough blah blah blah
