S and Tare mutually<br> exclusive events. Find P(sort)<br> P(S) = 12% P(T) =27%
mario62 [17]

The value of the probability P(S or T) is 39%

<h3>How to determine the probability?</h3>

The probability values are given as:

P(S) = 12% P(T) =27%

For mutually exclusive events,

P(S or T) = P(S) + P(T)

This gives

P(S or T) = 12% + 27%

Evaluate the sum

P(S or T) = 39%

Hence, the value of the probability P(S or T) is 39%

In 2017 there were enough renewable energy sources to supply a total of 9309 megawatts of electricity in a country. This graph s
STatiana [176]

Approximately 1700 megawatts of electricity could be supplied by Hydropower in 2017. Option B is correct.

Given that,
In 2017 there were enough renewable energy sources to supply a total of 9309 megawatts of electricity in a country. The graph shows the proportions that the different renewable energy sources could supply.

<h3>What are percentages?</h3>

the percentage is the ratio of the composition of matter to the overall composition of matter multiplied by 100.

Here, from the graph contribution of the hydropower is 18.2%.
So the electricity produced through hydropower is,
= 9309 * 18.2%
= 9309 * 18.2/100
= 1694.23
≈ 1700 megawatts

Thus, approximately 1700 megawatts of electricity could be supplied by Hydropower in 2017.

Find a formula for an arithmetic sequence that begins 80, 83, 86, 89, ...​
mel-nik [20]

Answer:

a_{n} = 3n + 77

Step-by-step explanation:

The nth term of an arithmetic sequence is

a_{n} = a₁ + (n - 1)d

where a₁ is the first term and d the common difference

Here a₁ = 80 and d = a₂ - a₁ = 83 - 80 = 3 , then

a_{n} = 80 + 3(n - 1) = 80 + 3n - 3 = 3n + 77
