Answer:

Step-by-step explanation:

The difference between 79 and 22 is 57. 79 is THE number. All you have to do is add 22 and 57 because the answer you get would ALWAYS have one of the numbers added as the difference.

HELP. Georgina wants to make a 42% citric acid solution. If she has 0.5 liters of water, how many liters of a 49% citric acid so

Alika [10]

Answer:

Georgina should add 3 liters of 49% citric acid solution.

Step-by-step explanation:

let x be the liters of 49% solution that Georgina should add. Then after she has added 0.5 liters of water, the total liters of solution she has will be

$x+0.5$

and 42% of this should be the solute:

$0.42(x+0.5)$

and since adding water does not add any solvent, this amount must come from the 49% citric acid solution; therefore

$0.42(x+0.5)=0.49x$

Solving for $x$ we get:

$\boxed{x= 3\:liters}$

This the amount of 49% citric acid solution Georgina must add.

If A=(0,0) and B=(6,3), what is the length of AB ?

motikmotik

D(AB) = √(6-0)^2 +(3-0)^2
d(AB) = √36+9
d(AB) = √45
d(AB) = 3√5
or
d(AB) = 6.71

hope it helps

(a) i. The probability mass function of X is 5 / 14

Hypergeometric Distribution is the probability distribution of a hypergeometric random variable.

The hypergeometric distribution is used to calculate the statistical importance of having drawn a specific k successes (out of n total draws) from the aforementioned population in the hypergeometric test uses.
