The manager of a video game store found that 35 of the 140 people who preordered the latest baseball game canceled their orders

Arte-miy333 [17]

Answer: $\frac{1}{16}$

Step-by-step explanation:

Given: The manager of a video game store found that 35 of the 140 people who preordered the latest baseball game canceled their orders the day before the game was released.

The probability that two customers who preorder the newest golf game will both cancel their orders the day before the game is released

$=\frac{35}{140}\times\frac{35}{140}=\frac{1}{4}\times\frac{1}{4}=\frac{1}{16}$

Hence, The probability that two customers who preorder the newest golf game will both cancel their orders the day before the game is released is $\frac{1}{16}$ .

Enter the expression 2cos2(θ)−1 , where θ is the lowercase Greek letter theta. 2cos2(θ)−1 2 c o s 2 ( θ ) − 1 = nothing

We have to evaluate

=2 cos 2Ф - 1

⇒cos 2Ф

A =2cos²Ф-1

B =1 -2 sin²Ф

C = cos²Ф - sin²Ф

Possible Answers are

=2 ×(2cos²Ф-1)-1

=4cos²Ф-2-1

=4cos²Ф - 3

=2×(1 -2 sin²Ф)-1

=2- 4sin²Ф-1

=1 - 4sin²Ф

=2× ( cos²Ф - sin²Ф) -1

=2 cos²Ф - 2sin²Ф-1

Equilateral triangle ABC has a perimeter of 96 millimeters. A perpendicular bisector is drawn from angle A to side Line segment

prisoha [69]

Answer:

Step-by-step explanation:

An equilateral triangle is a triangle that has all of its sides equal.

Perimeter of an equilaterial triangle = 3s where;

s is one side of the triangle.

Given the perimeter of ABC = 96mm

Substituting into the formula above to get s;

96 = 3s

s = 96/3

s = 32mm

Hence the length of one side of the triangle is 32mm

If a perpendicular bisector is drawn from angle A to side Line segment B C at point M, then MC will be half of BC and ΔAMC will be a right angled triangle.

Since all the sides of the triangle are equal, hence BC = 32mm. Since MC is the half of BC, then MC = 1/2 of 32mm

MC = 1/2 * 32mm

MC = 16mm

<em>Hence the length of Line segment MC is 16mm</em>
