Answer:

a. 1.5

b. 0.2

c -1.9

Step-by-step explanation:

The computation of the z scores of each of the following data values are as follows:

As we know that

z = (data values - mean)÷ standard deviation

Now

a. The z value is

= (40 - 25) ÷ (10)

=  1.5

b. The z value is

= (27 - 25) ÷ 10

= 0.2

c. The z value is

= (6 - 25) ÷ 10

= -1.9

Does the equation specify a function with independent variable​ x? If​ so, find the domain of the function. If​ not, find a valu
drek231 [11]

Yes, the equation specifies a function with independent variable​ x.

Equation: 6x + 19y = 7

This can be put in y = mx + b form,

6x + 19y = 7

19y = -6x + 7

y = -\frac{6}{19}x + \frac{7}{19}

Since the equation can be put in the form of a linear function, the domain is all read numbers (-∞,∞) or -∞ < x < ∞ .
