Find the total number of dogs by adding each day:
Total dogs = 23
Percent of dogs: Divide the number of dogs by the total number of patients:
= 23 / 50 = 0.46 x 100 = 46%
Use the given formula to find the standard error:
Standard error = √(0.46*(1-0.46)/50) = 0.07
90%: Find Z value for 90% ( 1.645) multiply by SE:
1.645 x 0.07 = 0.115 = 0.12
Now add and subtract that value from the Percent from above:
46 + 12 = 58%
46-12 = 34%
Answer (34%, 58%)
95%: Find Z value for 95% ( 1.96) multiply by SE:
1.96 x 0.07 = 0.137 = 0.14
Now add and subtract that value from the Percent from above:
46 + 14 = 60%
46-14 = 32%
Answer (32%, 60%)
Answer:
0.2
Step-by-step explanation:
Graph each side of the equation. The solution is the x-value of the point of intersection.
Answer:
△E'L'M'
Step-by-step explanation:
-90° rotation = 270° rotation
Which maps (x,y) onto (y,-x)
L' (2,-3)
M' (7,-6)
E' (-3,-7)
8.752 divided by 0.12 is 72.93.
I think it is option C, i am not sure tho.
