1.Which statement about the equation is true? x + 2 = x + 4 2. 5(w−1)−2=5w+7

Mathematics
1 answer:

Answer:

Both equations have no solution.

Step-by-step explanation:

The first equation is:

x + 2 = x + 4

Group the similar terms to get:

x  - x =  4 - 2

0 =  - 2

This equation has no solution because

0 \ne - 2

The second equation is

5(w - 1) - 2 = 5w + 7

We expand the parenthesis to obtain:

5w - 5 - 2 = 5w + 7

5w - 7= 5w + 7

Group similar terms:

5w -5w = 7 + 7

0 = 14

This equation does not also have solution because

0 \ne14

2-31 The following grade-point averages apply to a random sample of graduating seniors. 3.812.732.513.093.28 3.512.861.203.133.2
Dmitry_Shevchenko [17]

Answer:

The sample range is 2.61.

Step-by-step explanation:

We are given the following grade-point averages which apply to a random sample of graduating seniors below;

3.81, 2.73, 2.51, 3.09, 3.28, 3.51, 2.86, 1.20, 3.13, and 3.24.

As we know that the range of the data is calculated bu using the following formula;

               Range = Highest value in the data - Lowest value in the data

Here, Highest value = 3.81

          Lowest value = 1.20

So, the sample data range = 3.81 - 1.20

                                              = 2.61.
