Scientific notation can be scary but it really is simple
the exponent after the 10 is how many places you move the decimal. If it is positive you move it right, if it negative you move it left
2 x 10^2 means you move the decimal place right twice to make 200
4 x 10^-3 means you move the decimal place left three times to make .004
The question is asking you to multiply 900000 and .0000006
Answer: La respuesta es 28 y 29. Tengo que explicar?
Answer:
The value of x + y is -16.
Step-by-step explanation:
If each term is calculated by multiplying the previous one times 5 and then subtracting 20 from that result, then we can use that information to relate the first term (x) and the second one (0).
Following the info above, the following equation applies:
0 = 5 x - 20
then we solve for x:
5x = 20
x = 20/5
x = 4
Now we do the same study relating the second term (0) and the third one (y):
y = 5 (0) - 20
y = -20
Now that we have the value for both unknowns, we can estimate what they ask you: The value of x + y:
x + y = 4 + (-20) = 4 - 20 = -16
You write it out then you’ll get the exponent
Answer: (a) 0.317
(b) 0.167
(c) Not unusual
Step-by-step explanation:
Probability is defined as the chance of an event occurring.
Let S be a sample space and A be an event in the sample space, the probability of event A occurring can be found using the following:
P(A) = n(A) divided by n(S) where n(A) = number of elements in event A and n(S) = number of elements in the sample space.
(a) P(Right field) = Number of hits to the right field divided by total number of hits
= 1919/6060
= 19/60 which is approximately equal to 0.317
(b) P(Left field) = 1010/6060
= 1/6 which is approximately equal to 0.167
(c) The probability that the home run was hit to the left field is 0.167.
The probability of an unusual event is 0, therefore, it is possibly for the
player to hit a home run to the left.
