Create a program where you can add binary while they're still in binary form and convert them to decimal, adds them, then converts then back to binary. (without built in conversions).

Convert 34 to Binary Convert 22 to Binary Convert 1001 to Decimal Convert 111011 to Decimal Add 11 and 1110 in Binary Return the Answer in Binary Subtract 111 from 1010 in Binary, then Convert the Answer to Decimal

a. Why is it necessary to wash the filtered Ni(NH3)nCl2 crystals with concentrated NH3?

b. What method is used to determine the amount of NH3 in the coordination compound?

c. What method is used to determine the amount of Ni2+ in the coordination compound?

d. Calculate the absorbance of a sample with a %T of 3.98.

e. What is the concentration of Ni2+ in an unknown sample whose absorbance is 0.45 if a standard solution of 2M Ni2+ had an absorbance of 0.3?

There are 3 users, Smart, Tab, or PC that attempt to access an online store. The probability that seeing a smart is 0.5, Tab is 0.25, PC is 0.25. They either request either audio or video. Smart request audio with probability 0.5; tab request audio with probability of 0.4; and PC request audio with probability 0.3.

a) What is the probability that a user request video is a tablet?

b) What is the probability that a user request audio is a smart?

c) What is the probability that a user is PC and request video?

Three children, each of mass 15 kg, ride at the edge of a frictionless merry-go-round of mass 163 kg and radius 1.2 meters.  The children jump off outward, directly away from the center, taking zero angular momentum with them.   If the angular velocity of the merry-go-round before they jumped was  = 0.3 rad/s, what is its angular velocity after they jump?

Treat the merry-go-round as a solid cylinder.

2 sig figs, units (rad/s)

Two tennis players, A and B, are playing in a tournament; the first person to win 3 sets is declared the winner of the match (best of 5. no ties allowed) Assume that A is stronger and wins each set with probability of 0.6 and the outcome of each set is independent of other sets.

a.) What is the probability player A will win the match? (With explanation)

b.) Let A and B be events such that P(A) = 0.45, P(B) = 0.3, and P(A U B) = 0.6. Find P(A|B) and P(B|A). (With explanation) Thanks!!!!!!

A)The change of fish density is provided by the gas of negligible density in the fish bladder. If fish body density is 1.067 g/cm^3 , calculate the volume of the swim bladder (as percent of the total volume of fish) providing with the average density of 1.024 g/cm^3 .

B)When the rate of blood flow in aorta is 5 Liter/min , the velocity of the blood in capillaries is about 0.3 min/sec .

If the average diameter of capillary is 0.01 mm , calculate how many billions of capillaries in circulatory system.

For the Price Change data, please provide a 95% confidence interval on the variance. Select one: a. 0.10 to 2.1 b. 0.47 plus or minus 0.23 c. 0.30 to 1.50 d. 0.24 to 1.37
