Answer:
5 square inches
Step-by-step explanation:
First, we need to find the area of one sticky note:
The formula is Lenth*Width
Area of one sticky note:
5/6*2/3=10/18
=5/9 square inches
Now, we find the area of 9 sticky notes:
5/9*9=5
5 square inches
Hope this helps! Have an amazing day!
39 is A
40 is D
And that is my answer
Answer:
- number of multiplies is n!
- n=10, 3.6 ms
- n=15, 21.8 min
- n=20, 77.09 yr
- n=25, 4.9×10^8 yr
Step-by-step explanation:
Expansion of a 2×2 determinant requires 2 multiplications. Expansion of an n×n determinant multiplies each of the n elements of a row or column by its (n-1)×(n-1) cofactor determinant. Then the number of multiplies is ...
mpy[n] = n·mp[n-1]
mpy[2] = 2
So, ...
mpy[n] = n! . . . n ≥ 2
__
If each multiplication takes 1 nanosecond, then a 10×10 matrix requires ...
10! × 10^-9 s ≈ 0.0036288 s ≈ 0.004 s . . . for 10×10
Then the larger matrices take ...
n=15, 15! × 10^-9 ≈ 1307.67 s ≈ 21.8 min
n=20, 20! × 10^-9 ≈ 2.4329×10^9 s ≈ 77.09 years
n=25, 25! × 10^-9 ≈ 1.55112×10^16 s ≈ 4.915×10^8 years
_____
For the shorter time periods (less than 100 years), we use 365.25 days per year.
For the longer time periods (more than 400 years), we use 365.2425 days per year.
Answer:
when Y = 2, P(2) = 1/6 = 0.167
when Y = 3, P(3) = 2/6 = 0.333
when Y = 4, P(4) = 3/6 = 0.5
Step-by-step explanation:
Total number of possible ways to choose 2 components for defectives out of 4 components = 4C2 = 6
Y can only take values of 2, 3 and 4
So, Probability of Y = P(Y) = 1C(Y-1) / 6
when Y = 2, P(2) = 1/6 = 0.167
when Y = 3, P(3) = 2/6 = 0.333
when Y = 4, P(4) = 3/6 = 0.5
