Answer:
x = -2
Step-by-step explanation:
Solution:
-5x - 5y = 25 -(1)
3x + 5y = -21 -(2)
Adding (1) and (2),
-5x - 5y + 3x + 5y = 25 - 21
-5x + 3x -5y + 5y = 4
-2x = 4
x = 4 / -2
Therefore, x = -2

Answer:
At 0.10 significance level, reject H0
At 0.05 significance level, reject H0
At 0.01 significance level, fail to reject H0
At 0.001 significance level, fail to reject H0
Step-by-step explanation:
The null hypothesis is rejected if the p-value is less than or equal to the significance level.
Fail to reject the null hypothesis if the p-value is greater than the significance level.
At 0.1 and 0.05 significance level, the null hypothesis is rejected because the p-value (0.0174) is less than the significance levels.
At 0.01 and 0.001 significance level, fail to reject the null hypothesis because the p-value (0.0174) is greater than the significance levels.
I believe it's the second answer, where "the test contains 10 3-point questions and 14 5-point questions."
The absolute value of the number plotted on the number line is; 0.5
<h3>How to find Absolute Value?</h3>
The absolute value (or modulus) | x | of a real number x is the non-negative value of x without regard to its sign. For example, the absolute value of 5 is 5, and the absolute value of −5 is also 5. The absolute value of a number may be thought of as its distance from zero along real number line
Thus, if 0.5 is marked on the number line, from the given options, we can say that if we apply the definition above that |0.5| = 0.5
