Answer: Your answer is 3.5 miles per hour.
Step-by-step explanation:
Answer:
x = 1
Step-by-step explanation:
Step 1: Write equation
9 - 2x = 7x
Step 2: Solve for <em>x</em>
<u>Add 2x on both sides:</u> 9 = 9x
<u>Divide both sides by 9:</u> x = 1
Step 3: Check
<em>Plug in x to verify it's a solution.</em>
9 - 2(1) = 7(1)
9 - 2 = 7
7 = 7
Answer:
21.77% probability that the antenna will be struck exactly once during this time period.
Step-by-step explanation:
In a Poisson distribution, the probability that X represents the number of successes of a random variable is given by the following formula:

In which
x is the number of sucesses
e = 2.71828 is the Euler number
is the mean in the given interval.
In this question:

Find the probability that the antenna will be struck exactly once during this time period.
This is P(X = 1).


21.77% probability that the antenna will be struck exactly once during this time period.
Erotically angles are opposite each other and equal the same degree.
In the image 5x and 120 are vertical angles so 5x needs to equal 120.
X = 120/5
X = 24
