Answer:
Step-by-step explanation:
Mod of any number represents the absolute value of the number.
Therefore, = 2.25
Now we can arrange these numbers in ascending order.
-2.25 < -1.25 < 0.75 < 1.25 < 1.75 < 2.25
Therefore,
To make it much easier, it should be converted to the slope-intercept form
y = mx + b
To do so, 14x + 34y = 1 turns to:
34y = -14x + 1
Divide both sides by 34:
Simplified:
Answer:
Here is the graph:
y = mx + b
To do so, 14x + 34y = 1 turns to:
34y = -14x + 1
Divide both sides by 34:

Answer:
Step-by-step explanation:
Given that:
mean μ = 70
sample size = 25
sample mean = 73
standard deviation = 7
level of significance = 0.10
The null hypothesis and the alternative hypothesis can be computed as follows:
The z score for this statistics can be calculated by using the formula:
z = 2.143
At level of significance of 0.10
degree of freedom = n -1
degree of freedom = 25 - 1
degree of freedom = 24
The p - value from the z score at level of significance of 0.10 and degree of freedom of 24 is:
P - value = 1 - (Z < 2.143)
P - value = 1 - 0.9839
P - value = 0.0161
Decision Rule: since P value is lesser than the level of significance, we reject the null hypothesis.
Conclusion: We conclude that energy drink consumption increases heart rate.
