Answer:
See below.
Step-by-step explanation:
Let x equal each of the values on the table, and find the value of the function for that value of x.
f(x) = 5x - 5
x = -4
f(-4) = 5(-4) - 5
f(-4) = -20 - 5
f(-4) = -25
x = 0
f(0) = 5(0) - 5
f(0) = 0 - 5
f(0) = -5
x = 1
f(1) = 5(1) - 5
f(1) = 5 - 5
f(1) = 0
x = 3
f(3) = 5(3) - 5
f(3) = 15 - 5
f(3) = 10
x = 5
f(5) = 5(5) - 5
f(5) = 25 - 5
f(5) = 20
x f(x)
-4 -25
0 5
1 0
3 10
5 20
Answer:
its simple just add all of the numbers and then divide it by the total frequency

Answer:
Yes, hypertension drugs lowers blood pressure.
Step-by-step explanation:
Claim: The hypertension medicine lowered blood pressure.
The null and alternative hypothesis is
H0:\mu_{d}\geq 0
H1:\mu_{d}< 0
Level of significance = 0.05
Sample size = n = 13
Sample mean of difference = \bar{d} = 10.1
Sample standard deviation of difference = s_{d} = 11.2
Test statistic is
t=\frac{\bar{d}}{s_{d}/\sqrt{n}}
t = ((10.1) / (11.2 /squre root of 13)) = 3.251
Degrees of freedom = n - 1 = 13 - 1 = 12
Critical value =2.179( Using t table)
Test statistic | t | > critical value we reject null hypothesis.
In Conclusion: The hypertension medicine lowered blood pressure
Important: Please express exponents properly: -2x^2 Correct
-2x2 Not correct
Rewrite <span>(-2x2 -6x + 7) - (3x3 - 5x + 14)
as
</span><span>- 2x^2 -6x + 7
</span><span>- (3x^3 - 5x + 14)
__________________
Even better, write each power of x in its own column:
</span>- 2x^2 -6x + 7 - 2x^2 -6x + 7
- 3x^3 + 5x -14 - 3x^3 + 5x -14
