Answer:
4/663
Step-by-step explanation:
Probability is the likelihood or chance that an event will occur.
Probability = Expected outcome/Total outcome
Since we are to draw from a pack of card, the total outcome will be 52
Since there are 4 hearts;
Pr(selecting heart) = 4/52 = 1/13
If a club is then selected without replacement, the total number of card remaining will be 51;
Pr(selecting a heart) = 4/51
probability of drawing a heart and a club in that order = 4/52 * 4/51
probability of drawing a heart and a club in that order = 16/2652
probability of drawing a heart and a club in that order = 4/663
Answer:
The animal farm should buy 1.775 bags of soybeans and 1.575 bags of oats

Step-by-step explanation:
The given parameters can be summarized as:

Where: x = Soybeans and y = Oats.
So, the system of equations are:




The best way to solve this, is using graph
Plot the following equations on a graph, and get the points of intersection:



From the attached graph, we have:



Substitute each of the values of x's and y's in the cost function to get the minimum cost:










The values of x and y that gives the minimum cost is:

and the minimum cost is:

Hence, the animal farm should buy 1.775 bags of soybeans and 1.575 bags of oats

Step-by-step explanation: i just know
Answer: 37.5
Explanation: find the surface area of one side, which is 2.5*2.5=6.25 then multiply that product by six, since there’s six sides in a square, and you’ll get 37.5
