Answer:

sin a=3/5

cos a=4/5

Step-by-step explanation:

<u>sin</u> <u>A</u>

AB(squared)=AC (squared)+CB(squared) AB(squared)=4(squared)+3(squared)

AB (squared)=16+9

AB (you must put a square root over AB)=25(remember 25 is now a square root)

AB=5

sin a=opposite/hypotenuse

=3/5

<u>cos A</u>

cos a=adjacent/hypotenuse

=4/5

Solve the linear programming problem.<br><br> Maximize and minimize<br><br> z=4x+5y
Mrrafil [7]

Answer:

26

Step-by-step explanation:

The objective function is;

z(x,y)=4x+5y

The vertices of the feasible region are  (0,4), (4,2) and (5,0) and (0,0)'

We substitute the vertices into the objective function to get;

At (0,4);

z(0,4)=4(0)+5(4)=20

At (0,4);

z(4,2)=4(4)+5(2)=26

At (5,0);

z(5,0)=4(5)+5(0)=20

At (0,0);

z(0,0)=4(0)+5(0)=0

Therefore the maximum value is 26

The time it takes me to wash the dishes is uniformly distributed between 5 minutes and 12 minutes. What is the probability that
GalinKa [24]

Answer:

0.2857

Step-by-step explanation:

We define the time it takes to do these dishes to be uniformly distributed between the time 5 minutes and 12 minutes.

a = 5 minutes

b = 12 minutes

Probability of tonight's dish washing being between 6 and 8 minutes

P(6<X<8)

= 8-6/b-a

= 2/12-5

= 2/7

= 0.2857

The probability it will be better 6 and 8 minutes is therefore 0.2857
