Answer:
Step-by-step explanation:
<u>Since T is midpoint, ST and TU have equal length:</u>
<u>Substitute the values and solve for x:</u>
- 6x - 8 = 4x + 9
- 6x - 4x = 9 + 8
- 2x = 17
- x = 17/2
- x = 8.5

Step-by-step explanation:
Inequality that represents the lengths of the glass:
12 cm < x ≤ 12.2 cm
<h2>
Answer with explanation:</h2>
Given : In a restaurant, the proportion of people who order coffee with their dinner is p.
Sample size : n= 144
x= 120

The null and the alternative hypotheses if you want to test if p is greater than or equal to 0.85 will be :-
Null hypothesis :
[ it takes equality (=, ≤, ≥) ]
Alternative hypothesis :
[its exactly opposite of null hypothesis]
∵Alternative hypothesis is left tailed, so the test is a left tailed test.
Test statistic : 

Using z-vale table ,
Critical value for 0.05 significance ( left-tailed test)=-1.645
Since the calculated value of test statistic is greater than the critical value , so we failed to reject the null hypothesis.
Conclusion : We have enough evidence to support the claim that p is greater than or equal to 0.85.
