A regular hexagon is dilated by a scale factor of 75 to create a new hexagon. How does the perimeter of the new hexagon compare
mezya [45]
Let the length of the original hexagon be x:
the perimeter of the hexagon will be:
P=length*number of sides
P=6*x=6x
After the dilation the new length became:
length=scale factor × original length
=75 × x
=75x
thus the new perimeter will be:
6×75x
=450x
hence the new perimeter compared to the old one will be:
450x/6x
=75
the new perimeter is 75 times the old one

Two fair dice are tossed, and the up face on each die is recorded. Find the probability of observing each of the following event
Kamila [148]

Answer:

Step-by-step explanation:

When two fair dice are tossed sample space consists of 36 events

(1,1)....(6,6)

A_ The difference of numbers is 2 or less

Favorable outcomes = (1,1) (1,2) (1,3) (2,1) (2,2)(2,3) (2,4) (3,1) (3,2) (3,3) (3,4) (3,5) (4,2) (4,3)(4,5) (4,6) (5,3) (5,4) (5,6)\\

Hence Probability = \frac{19}{36}

B) A 4 does not appear on either die

Then we must not have these

(4,1)(4,2)(4,3) (4,4) (4,5) (4,6)\\(1,4) (2,4) (3,4) (5,4) (6,4)

Hence probability = \frac{36-11}{36} =\frac{25}{36}

C:  The sum of numbers is 10 or more:

FAvourable outcomes are:

(4,6) (5,5) (5,6) (6,5) (6,4)

Probability = \frac{5}{36}
