Answer:
it would take 36 apples to make 4 pies.
Step-by-step explanation:
9 x 4 = 36
4+4+4+4+4+4+4+4+4= 36
Answer:
x = 8
z = 65
Step-by-step explanation:
Through various rules, we are able to assert: (6x + 67)° = 115°.
Now, we want to solve for x:
6x + 67 = 115
6x = 48
x = 8
We know that z° is equal to the complement of (6x + 67)°, and together these must sum to 180°. Therefore, we can simply take 180° - 115° to find that z° = 65°.
Answer: Relative risk of anxiety associated with coffee use is 5 times the anxiety associated with non coffee use.
Step-by-step explanation:
Since we have given that
Number of coffee drinkers = 10000
Number of whom developed anxiety = 500
Number of non coffee drinkers = 20000
Number of whom developed anxiety = 200
So, probability of getting anxiety from coffee drinkers = ![\dfrac{500}{10000}=0.05](https://tex.z-dn.net/?f=%5Cdfrac%7B500%7D%7B10000%7D%3D0.05)
Probability of getting anxiety from non coffee drinkers = ![\dfrac{200}{20000}=0.01](https://tex.z-dn.net/?f=%5Cdfrac%7B200%7D%7B20000%7D%3D0.01)
so, Relative risk of anxiety associated with coffee use is given by
![\dfrac{0.05}{0.01}=5](https://tex.z-dn.net/?f=%5Cdfrac%7B0.05%7D%7B0.01%7D%3D5)
Hence, Relative risk of anxiety associated with coffee use is 5 times the anxiety associated with non coffee use.
