Answer:
its hard to explain as a simple answer but i can explain w an example
Step-by-step explanation:
lets say the equation is 2 (3×5), rather than using pemdas and doing 3×5 fist, you take the 2 amd multiply it by the numbers in the paranthesis, so, do that snd u get 2×3 which equals 6 and then u do 2×5 which equals 10 so the equation in the end should be 6+10 which equals 16, and obviously if u use pemdas u would gey a different answer (the answer if u use pemdas is 30)
Answer:
Son's age = 20 years
Father's age = 60 years
Step-by-step explanation:
Let son's age be x
Fathers age = 3x
Ten years ago:
Sons age = x - 10
Fathers age = 3x - 10
3x -10 = 5 * (x-10)
3x - 10 = 5x - 50
50 -10 = 5x - 3x
40 = 2x
x = 40/2
x =20
Son's age = 20 years
Father's age = 60 years
Answer:
a)
b)
c)
d) For this case we can find first this probability:
And then using the complement rule we got:
Step-by-step explanation:
For this case we define two events A and B with the following probabilities:
And we want to find the following probabilities:
(a) P (A')
For this case we can use the complement rule and we got:
(b) P (A U B)
For this case we can use the total probability rule and we got:
And if we replace we got:
(c) P [(A U B)']
For this case we can use the complement rule again and we have this:
(d) P (A' U B)'
For this case we can find first this probability:
And then using the complement rule we got:
Answer:
36%
Step-by-step explanation:
20 % solution in 4/5 parts of the mmixture gives 80/5
100% solution in 1/5 parts of the mixture gives 100/5
total would give 80+100/5= 36% solution
