Answer:
where are the patternes that are supposed to be shown?
Step-by-step explanation:
it says : Which pair of patterns below represents that of Edward and Juan?
but there are no patterns shown
The score set above has no mode
This is because mode is a measure of what score occurs the most
In this score set no numbers occur more than once
The best interpretation is that the sum of 2.1 and –1.2 times a number is greater than or equal to 8.
<h3>Inequality functions</h3>
Inequality are expressions not separated by an equal sign, Given the inequality;
2.1 + (-1.2x) ≥ 8
The sign ≥ means greater than or equal to
The expression 2.1 + (-1.2x) ≥ 8 can also be expressed as 2.1 - 1.2x ≥ 8
The best interpretation is that the sum of 2.1 and –1.2 times a number is greater than or equal to 8.

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
Answer:
A
Step-by-step explanation:
Two angles are complementary if their angles add up to 90
let x= angle b
35+x=90
x=55
