Answer:

<u>678.4 cm^2</u>

Step-by-step explanation:

total surface area of prism is equal to ph+2B where <em>p</em> represents the perimeter of the base, <em>h</em> the height of the prism and <em>B</em> the area of the base.

Firstly, we calculate the <u>perimeter of the base. </u><u>This is equal to 10 + 14 + 10 + 14, or 48.</u>

Secondly, we must calculate the <u>height of the prism, </u><u>which is shown as 8.3.</u>

Lastly, we must calculate the <u>area of the base, </u><u>which is 10 * 14, or 140.</u>

We can now substitute these values into the formula, ph + 2B to find the total surface area of the prism:

ph + 2B,

(48)(8.3) + 2(140),

398.4 + 280,

678.4

<em><u>This means that the total surface area of this prism is 678.4 cm^2</u></em>

For an outdoor concert by the city​ orchestra, concert organizers estimate that 19 comma 000 people will attend if it is not rai
Amiraneli [1.4K]

Answer:

14,800 people are expected to attend the concert

Step-by-step explanation:

In this question, we are tasked with calculating the expected number of people that will attend a concert on a particular day.

The key to answering this question is to multiply the individual probabilities of the two events by the expected number of people

Mathematically, what we obtain is the following;

The expected number of people at the concert = (probability of raining × expected number of people when it rains) + (probability of not raining × Expected number of people when it does not rain)

From the question, we identify that;

Probability of raining = 30% = 30/100 = 0.3

Probability of not raining = 1-probability of raining = 1-0.3 = 0.7

Expected number of people when it rains = 5,000

Expected number of people when there is no rain = 19,000

we plus these vales into the equation we have;

The expected number of people at the concert =( 0.3 × 5,000) + (0.7 × 19,000) = 1,500 + 13,300 = 14,800 people
