Answer:
3/5
Step-by-step explanation:
There are 20 balls, numbered 1 through 20.
Of these, 10 are even, 4 are less than five, and 2 are both even and less than 5.
So the probability is:
P(even or <5) = P(even) + P(<5) − P(even and <5)
P(even or <5) = 10/20 + 4/20 − 2/20
P(even or <5) = 12/20
P(even or <5) = 3/5
2n^2 + 4n + 2 = 0
Divide both sides by 2:
n^2 + 2n + 1 = 0
Find two numbers that multiply to form C (1) and add together to form 2: these numbers are 1 and 1:
(n +1)(n+1) = 0
(n+1)^2 = 0
Therefore n+1 = 0
n = -1
Answer:
The units of the two shapes are not the same one is in cm the other in mm
Step-by-step explanation:
1cm=10mm
15÷10=1.5cm
12÷10=1.2cm
1.2×1.5=1.8
72- area of B
Area of B take away the area of A
72- 1.8
Answer=70.2cm
If you enlarge it 6 times, then you get 24in that become 2ft and 36in that become 3ft. If the formula for calculating the area is a times b, then you have to do 2ft x 3ft and you get 6ft2
So the answer is <span>A. 6 ft2</span>
