We have the following expression:
(6.34 x 10 ^ -7) (4.5 x 10 ^ 3)
The solution shown is:
(6.34 x 10 ^ -7) (4.5 x 10 ^ 3)
(6.34 x 4.5) (10 ^ -7 x 10 ^ 3)
28.53 x 10 ^ -4
-28.53 x 10 ^ 4
-2.853 x 10 ^ 3
The errors are:
A. He changed the sign of the coefficient. A negative exponent does not affect the sign of a coefficient in scientific notation. The sign of the exponent determines the direction the decimal is moved in.
D. He got the wrong value for the coefficients; 28.53 x 10^-4 is not possible. The coefficients in scientific notation are always greater than 1, but less than 10.
Hey ,here is the answer to ur question....!
(a).p(that the first card is a queen)=4/52=2/26=1/13
P(the card is a queen if the sampling is done without replacement)=3/52
(B).p(the first card is a queen)=4/52=1/13
P(the second card is queen of the sampling is done with replacement)=1/13....
Hope this helps you....!
Answer: 15
Step-by-step explanation:
Ratio is 1 inch:6 mile
