Answer:
1/2
Step-by-step explanation:
16^-1/4
We know that a^ -b = 1/a^b
1/( 16^1/4)
Rewriting 16 as 2^4
1/( 2^4^1/4)
We know that a^b^c = a^ (b*c)
1/( 2^(4*4))
1/2^1
1/2
Given:
50% of the people that get mail-order catalogs order something.
Determine the probability that exactly 2 out of 10 people getting the catalogs will order something.
If the total number of people is 10, we can calculate the number of people who will order something from the catalogs:
10 * 0.50 = 5 people.
The probability that exactly two out of ten people will order something is:
2/5 = 0.4
Therefore, there is a 40% chance that the exact two people who received the catalogs will order something from it.
Answer:
Step-by-step explanation:
Let the width of the rectangle = x
As length is 5 inches longer than width, we have to add 5 to width
Length = x + 5
Perimeter of ractangle = 56 in
2* (length + width) = 56
2*( x + 5 + x) = 56
2* (2x + 5) = 56
Use distributive property: a*(b +c) =(a*b) + (a * c)
2*2x + 2*5 = 56
4x + 10 = 56
Subtract 10 from both sides
4x = 56- 10
4x = 46
Divide both sides by 4
x = 46/4
x = 11.5
Width = 11.5 in
length = 11.5 + 5
= 16.5 in
