Answer:
8 oz.
Step-by-step explanation:
One pound is 16oz and ½ of that is 8oz
If A(t) is the amount of salt in the tank at time t, then A(0) = 50 g and
A'(t) = (1 g/L)*(3 L/min) - (A(t)/120 g/L)*(3 L/min)
Multiply both sides by 
, so that the left side can be condensed as the derivative of a product:
Integrate both sides and solve for A(t).
Given that A(0) = 50 g, we have
so that the amount of salt in the tank at time t is
5. Y,45 is the axial amount of the y axis items 5
Answer:
25%
Step-by-step explanation:
Assuming that each child can only be a boy or a girl, then each child will have a probability of 0.5 or 50% of being either gender. Therefore, since we need to find the probability of at least 2 being boys then we simply need to multiply this probability twice.
0.50 * 0.50 = 0.25 or 25%
Using this data we can say that there is a 25% probability of there being at least 2 boys in the family.
