The angle of rotation of a polygon is found using the formula 360/n

Where n is the number of sides.

Shape 1: 360 / 10 = 36

Shape 2: 360 /4 = 90

Shape 3: 360 /5 = 72

Shape 4: 360/8 = 45

Shape 5: 360/3 = 120

Shape 6: circles = 1

Shape 7: 360 /6 = 60

Shape 8: 360 / 12 = 30

There are 3 shapes that are 72 or higher.

The probability that the San Jose Sharks will win any given game is 0.3694 based on a 13-year win history of 382 wins out of 1,0

Answer:

4.43

Step-by-step explanation:

Given :The probability that the San Jose Sharks will win any given game is 0.3694 based on a 13-year win history of 382 wins out of 1,034 games played

To Find : What is the expected number of wins for the that upcoming month?

Solution :

The probability that the San Jose Sharks will win is 0.3694

Let X = number of games won

Total no. of games = 12

We are supposed to find the expected number of wins for the that upcoming month

So, expected number of wins = E(X)=XP(X)= $12 \times 0.3694 =4.43$

Hence the expected number of wins for the that upcoming month is 4.43

The sum of the reciprocals of two consecutive even integers is 3/4 Find the two integers.

Vedmedyk [2.9K]

$\Large{ \underline{ \underline{ \bf{ \orange{Solution:}}}}}$

Let one of those even numbers be x, Then other even number would be x + 2.

According to question,

⇛ Their reciprocal add upto 3/4

So, we can write it as,

⇛ 1/x + 1/x + 2 = 3/4

⇛ x + 2 + x / x(x + 2) = 3/4

⇛ 2x + 2 / x² + 2x = 3/4

Cross multiplying,

⇛ 3(x² + 2x) = 4(2x + 2)

⇛ 3x² + 6x = 8x + 8

⇛ 3x² - 2x - 8 = 0

⇛ 3x² - 6x + 4x - 8 = 0

⇛ 3x(x - 2) + 4(x - 2) = 0

⇛ (3x + 4)(x - 2) = 0

Then, x = -4/3 or 2

☃️ It can't be -4/3 because it is fraction and negative number. So, x = 2

Then, x + 2 = 4

✤ So, The even numbers are 2 and 4.
