Given : In a study investigating a link between walking and improved health, researchers reported that adults walked an average of 873 minutes in the past month for the purpose of health or recreation.
Claim : The true average number of minutes in the past month that adults walked for the purpose of health or recreation is lower than 873 minutes.
i.e. 
We know that the null hypothesis contains equal sign , then the set of hypothesis for the given situation will be :-

Answer:
4h²– 19h – 30
Step-by-step explanation:
(4h+5)(h-6)
=4h²–24h+5h–30
=4h²–19h–30
Answer:
5) we get a=6
6) we get c=8
Step-by-step explanation:
The triangles given are similar.
When the triangles are similar, the ratio of corresponding sides are also similar.
5) If c = 12, find a
We will use the ratio
Now cross multiply to find value of a
So, we get a=6
6. If b = 6.4, find c
We will use the ratio
Now cross multiply to find value of b
So, we get c=8
