Answer:
0
Step-by-step explanation:
Given that:
The probability of event A = 0.4
i.e. P(A) = 0.4
The probability of event B = 0.5
P(B) = 0.5
Given that A and B are disjoint, then they do not have any elements in common. Thus, the probability that both events will occur is;
P(A ∩ B) = empty set {}, and the cardinality of the intersection of these two disjoint sets are, therefore, zero (0).
Answer:
Mass of proton (m) = 1.67×10^(-27) kg
Step-by-step explanation:
Mass of proton (m) = 1.67×10^(-27) kg.
Since, 1 kg = 1000 g
Therefore, m = 1.67x10^(-27+3) g = 1.67x10^(-24) g
Let N no. of protons be present in 1 g. Hence, Nxm = 1 g
So, N = 1 / m = 1 / (1.67x10^(-24))
N = 6x10^(23) (approx.)
Exact mass of proton gives N = 6.022 x 10^(23).
That is a very special no. In fact, it is the Avogadro’s constant used frequently in chemistry. Avogadro’s no. is actually the number of atoms in exactly 12 g of C-12 isotope of carbon. Since, the atomic mass of C-12 is 12 u (unified mass), then again the no. of carbon atoms turn out to be N.
Answer:
So she can get the one 11in x 15in and then 10 3in x 5in
Step-by-step explanation:
The most she can spend is $11. and 11in x 14in photo would be to expensive to get 2 of them... sooo that one photo takes of 7
11-7= 4
A 3in x 5in photo cost just $.40 center (don't forget the decimal!)
So then you see how many times .40 will go into 4
4/.4 = 10
or .4z= 4; z= 10
