The area of the triangle is expressed as 2.718cm²

<h3>Area of a triangle</h3>

The formula for calculating the area of a triangle is expressed as:

A = 0.5absinФ

  • a and b are the sides
  • Ф is the angle

Given the following

  • p = 2.5 cm
  • n = 2.3 cm and;
  • ∠O=71°

Substitute the given parameters to have:

Area = 0.5(2.5)(2.3)sin71

Area = 2.718cm²

Hence the area of the triangle is expressed as 2.718cm²

in a certain group of students, the probability of a randomly chosen students being male is 40%, the probability of the students
melamori03 [73]

Divide the 5% of Spanish by 40% male:

0.05 / 0.40 = 0.125

Change to a percent by multiplying by 100:

0.125 x 100 = 12.5%

The answer is a. 12.5%

Vikentia [17]

Answer:

the other side would be 15

The probability of tossing heads with a standard coin is 1/2, because it is one of two possible outcomes. The probability of tos
spayn [35]

Answer:

  a) 1/64

  b) 1/4096

Step-by-step explanation:

As you can tell from the example, the exponent of 1/2 is the number of heads in a row.

a) p(6 heads in a row) = (1/2)^6 = 1/(2^6) = 1/64

b) p(12 heads in a row) = (1/2)^12 = 1/(2^12) = 1/4096

_____

<em>Additional comment</em>

The probability of a head is 1/2 because we generally are concerned with a "fair coin." That is defined as a coin in which each of the 2 possible outcomes has the same probability, 1/2. Similarly, a "fair number cube" has 6 faces, and the probability of each is defined to be the same as any other, 1/6. Loaded dice and unfair coins do sometimes show up in probability problems.

3x + 9b + 5ax + 15ab​
Irina-Kira [14]

Answer:

(x + 3b)(3 + 5a)

Step-by-step explanation:

Assuming you require the expression factorised.

Given

3x + 9b + 5ax + 15ab ( factor the first/second and third/fourth terms )

= 3(x + 3b) + 5a(x + 3b) ← factor out (x + 3b) from each term

= (x + 3b)(3 + 5a) ← in factored form
