Answer:

3x^2-x+5.2f\left(-3\right)-f\left(4\right) =

3x^2-x-19.6f

Step-by-step explanation:

3x^2-x+5.2f\left(-3\right)-f\left(4\right)

=3x^2-x-5.2f\cdot \:3-f\cdot \:4

Quadrilateral WXYZ is a Parallelogram. Find the value of each variable.
Arisa [49]

Answer: a=3, b=1

A parallelogram have its opposite sides equal and parallel.

Step-by-step explanation:

SO, the quadrilateral WXYZ have its opposite sides equal as its a parallelogram.

From the given figure the side XY= WZ and XW= YZ, which gives two equations i.e

   Equation 1 is    3a-4=a+2       and     Equation 2 is     b+1=2b

Solving Equation 1                                     Solving equation 2

                    3a-a = 2+4                                    2b-b = 1                          

                    2a   =  6                                              b=1

                       a   =  3                    

So, by solving the two equations a=3 and b=1.

In a class. 40% of the student's study math and science, 60% of the students study
GaryK [48]

Answer:

2/3

Step-by-step explanation:

A = Student studying Math

B = Student studying Science

P(B|A) = P(A and B) ÷ P(A).

P(B|A) means the probability of event B given event A.

Given :

P(A and B) = 0.40.

Also P(A) = 0.60.

P(B|A) = 0.40 ÷ 0.60 = 2 ÷ 3.

So, the answer is 2/3.
