((10.68÷9.99)−1)×100
=6.9%

Jawaban:

n(menang) = 6

n(seluruh) = 20

P(menang) = n(menang)/n(seluruh) = 6/20 = 3/10 atau 0,3 atau 30%

Response: B. 0.45

Detailed explanation:

According to the table provided, the total number of students is 137

The total of sophomore students is 35 + 42 = 77

Let A represent the event for sophomore students.

Thus, the probability of the students being sophomores is calculated as:

Out of these, the sophomore students who went to the jazz concert number 35

Let B denote the event of attending the jazz concert.

The probability of attending the jazz concert while being sophomores is calculated as:

Therefore, the probability that a student attended the jazz concert given that they are a sophomore is given by:-

The volume of a cylinder can be determined using the formula pi*h*d^2/4, which leads us to V = pi*(39 mm)(39 mm)^2 / 4 = 46,589 mm^3. Dividing the mass of 1 kg by the volume of 46,589 mm^3 results in a density of 2.1464 x 10^-5 kg/mm^3. Typically, density is expressed in kg/m^3, so we convert this by multiplying by 1x10^9, yielding a density of 21,464 kg/m^3.

(1 3/4) divided by (1/5) =
(7/4) ÷ (1/5) =
7/4 multiplied by 5/1 =
35/4 or 8 3/4 <===
