If the teacher were to take the number of students who only participated in math (40) and the number of students that participated in tutoring as a whole (40 + 55 + 47 + 58 = 200). She will get the percentage of people that were in math. 

She can then multiply the 100 students by the percentage of students that participated in math to predict about how many of the pool of 100 will be in math tutoring.

40 / 200 = 4 /20 = 1 / 5 = 0.20 = 20%

100 x 0.20 or 20% of 100 = 20. 

She can expect about 20 students out the whole 100-student pool to sign up and participate in math tutoring.

The variable x varies jointly with y and z. Use x=2, y=4, z=1 to write an equation relating x, y
kolbaska11 [484]

Answer:

Equation is x=\frac{1}{2}yz and when y=2 and z=4, x will be 4.

Step-by-step explanation:

Given:

x varies jointly with y and z.

It also means x is directly proportional to y and z.

x=2, y =4,z=1

From above values we can compute the equation as.

x=\frac{1}{2}yz\\2= \frac{1}{2} \times 4 \times 1\\2=2

Hence the Equation is x=\frac{1}{2}yz

Now y=2 and z=4 we get.

x=\frac{1}{2}\times 2 \times 4= 4

Hence when y=2 and z=4, x will be 4.
