3/5n - 4/5 = 1/5
3/5n = 1
n = 1/1 * 5/3
n = 5/3

3/5 n - 4/5 = 1/5. Add 4/5 on both sides and get 3/5n = 1. Therefore n equals 5/3. Hope this helps.

How much is 1.4 kg minus 650 grams
faltersainse [42]
First of all you have to convert kg to grams

.4 kg is 400g
1000+400= 1400g

1400-650 = 750 kg

that's your final answer

Situation D: Suppose that, in a one-minute period during an electrical storm, the number of lightning strikes on a radar antenna
Crank

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:

P(X = x) = \frac{e^{-\mu}*\mu^{x}}{(x)!}

In which

x is the number of sucesses

e = 2.71828 is the Euler number

\mu is the mean in the given interval.

In this question:

\mu = 2.40

Find the probability that the antenna will be struck exactly once during this time period.

This is P(X = 1).

P(X = x) = \frac{e^{-\mu}*\mu^{x}}{(x)!}

P(X = 1) = \frac{e^{-2.40}*2.40^{1}}{(1)!} = 0.2177

21.77% probability that the antenna will be struck exactly once during this time period.

Zepler [3.9K]

Answer:

6 tickets

Step-by-step explanation:

Amount spent by Mr Harrison on plane tickets = $3600

Cost of each ticket = $585

Thus, largest number of tickets purchased is;

n = 3600/585

n = 6.15

Approximating to the nearest whole number gives 6 tickets
