What we know here is that all 2500 shares together are worth 100 000 dollars in total. (it's 100 000.00 actually, but we can ignore the part after the point, as it's equal to 0).
This means that each of the shares is valid the whole sum divided by the number of shares, that is:
(first i divided both denominator and numerator by 100)
So each value is worth 40 dolars.
Answer:
8.1.
Step-by-step explanation:
a^2+b^2=c^2
8^2+2^2=c^2
64+4
68
and you square root it and get 8.2 so i giras is 8.1
hope it helps.
Answer: 0.12
Step-by-step explanation:
The expected number of accidents is a weighted average of the potential number of accidents and their probabilities:
= (0 * 0.935) + (1 * 0.03) + (2 * 0.02) + (3 * 0.01) + (4 * 0.005)
= 0.12
Answer:
(-1, 7, 2)
Step-by-step explanation:
we suppose that ax + by + cz = d for the matrix
D = det [ 0 4 7] = 100
-6 0 -2
1 2 8
Dx= det [ 14 4 7] = - 100
10 0 -2
-3 2 8
Dy= det [ 0 14 7] = 700
-6 10 -2
1 -3 8
Dz = det [ 0 4 14] = 200
-6 0 10
1 2 -3
So the solution is:
x = Dx/D = -1, y = Dy/D= 7, z =Dz/D = 2
(-1, 7, 2)
have a good day!
Answer:
False. The products from cross multiplication are different.
Step-by-step explanation:
To know if a pair of ratios form a proportion, cross multiply. If the products are equal, they are a proportion.
Write like this to see top (numerator) and bottom (denominator) clearly.
Multiply each numerator with the other side's denominator:
4 X 6 = 24
5 X 5 = 25
Are they equal? No. 24 ≠ 25
Therefore it's not a proportion.
