Answer:

1. x = 5    2. y = 4      3. x = -2

Step-by-step explanation:

2x - y = 9             -5x + 2y = 13       3x + 4y = -6

4x + y = 21            5x + y = -1         7x(-1) + 4y(-1) = -14(-1)   <(multiply all by -1)

6x = 30                      3y = 12        -4x = 8

6       6                        3       3          4       4

x = 5                            y = 4              x = -2

(B Fail to reject the null hypothesis. The​ P-value is greater than the level of significance.

The null hypothesis is a common arithmetic theory that asserts that no statistical relationship or significance exists between two sets of observed data and measured phenomena in a set of given, single, observed variables.

The null hypothesis is rejected, if the P-value is less than the level of significance.

Here, it is provided that the test is left-tailed and the z score is -1.23.

From, the table of the negative scores, the P-value for the left-tailed test is 0.1093.

Since the P-value (0.1093) is greater than the level of significance (0.05). The null hypothesis is not rejected.

Hence, the correct option is (B), Failing to reject the null hypothesis. The​ P-value is greater than the level of significance.

Answer:

2/3 = 8/12

Step-by-step explanation:

1/4 is equal to 3/12, because 1/4 times 3/3 (which is 1) equals to 3/12.

2/3 is not equal to 6/12, because 6/12 can be simplified to 1/2. 2/3 is greater  than 1/2, not equal to half. So, 2/3 times 4/4 (which is 1) equals to 8/12.

Hope this helps :)
