Answer:
A- impossible
B- unlikely
C- even chance
D- likely
E- certain
Step-by-step explanation:
A to E goes from 0 to 1 so I assume 0 means zero possibility (impossible) then to continue unlikely. now even chance at C (in the middle which makes sense) then likely and then 1 is certain
Answer:
$149.50
Step-by-step explanation:
Width = x
Length = 2x - 5
Perimeter of the room = 5x
Perimeter of the room = 2(length + width)
5x = 2{(2x-5) + x}
5x = 2(2x - 5 + x)
5x = 4x - 10 + 2x
5x = 6x - 10
5x - 6x = -10
-x = -10
x = 10
Width = x = 10
Length = 2x - 5
= 2*10 - 5
= 20 - 5
= 15
Perimeter of the room = 5x
= 5 × 10
= 50 square foot
If carpet costs $2.99 a square foot, what the total cost to carpet the living room
Total cost = $2.99 × 50
= $149.50
Answer:
Element wise subtraction.
Step-by-step explanation:
Matrix Subtraction is done element wise.
Therefore, D = ![\[ \left[ {\begin{array}{ccc} 3 & 1 & 0 \\ -1 & 2 & 4 \\9 & 7 & -2 \end{array} } \right]\]](https://tex.z-dn.net/?f=%5C%5B%20%20%5Cleft%5B%20%7B%5Cbegin%7Barray%7D%7Bccc%7D%20%20%203%20%26%201%20%26%200%20%5C%5C%20%20%20-1%20%26%202%20%26%204%20%5C%5C9%20%26%207%20%26%20-2%20%20%5Cend%7Barray%7D%20%7D%20%5Cright%5D%5C%5D)

This becomes:

Now, 
In this problem, the average is already given. In order to solve for the missing length of jump rope we have the following solution:
Let x = be the total length
X = 4(112)
X = 448
Therefore,
34m + 1m + 212m = 247m
448m - 247m = 201 length of the fourth jump rope
Answer:
B
Step-by-step explanation:
1/2x - 2 > 0
collect like terms
1/2x > 0 + 2
1/2x > 2
Divide both sides by 1/2
x > 2 divided by 1/2
inverse of 1/2 is 2/1
x > 2 times 2/1
x > 4
