Answer:

(8, 17)

Step-by-step explanation:

y= 3x -7 -----(1)

y= 2x +1 -----(2)

Substitute (1) into (2):

3x -7= 2x +1

Being x terms to one side, constant to the other:

3x -2x= 7 +1

x= 8

Substitute x= 8 into (2):

y= 2(8) +1

y= 16 +1

y= 17

∴ The solution is (8, 17).

To find:

Which of these types of sampling is used: random, stratified, systematic, cluster, convenience?

Explanation:

It is given that,

49, 34, and 48 students are selected from the Sophomore, Junior, and Senior classes with 496, 348, and 481 students respectively. 

That implies,

Which is the graph of f(x) = StartRoot x EndRoot?
Bingel [31]

The equation of the graph of f(x) = \sqrt x is (d) on a coordinate plane, an absolute value graph starts at (0, 0) and goes up through (4, 2).

The equation of the graph is represented as:

  • f(x) = \sqrt x

See attachment for the graph of f(x) = \sqrt x

From the attached graph, the curve passes through points (0,0) and (4,2).

Hence, the equation of the graph of f(x) = \sqrt x is (d)
