The answer is four so it would be #[
You can solve this problem by creating an equation. 200+25x=500.
200-200+25x=500-200
25x=300
25x/25=300/25
x=12
So Keith can withdraw $25 for 12 weeks.
Answer: Estimated standard error for the sample mean difference would be 1.
Step-by-step explanation:
Since we have given that
Mean of MD = 4.90
So, Sum of difference would be
S = 288
n = 9
We need to find the standard error for the sample mean differences.
Estimated standard error for the sampled mean difference would be
Hence, estimated standard error for the sample mean difference would be 1.
I can't understand what you wanted with the second question (or if that is even a question), but the answer to the first one is 42.
Answer:
Option D.
Step-by-step explanation:
If two triangles ΔABC and ΔA'B'C' are similar then we take point C of ΔABC to find the transformation performed form C to C'.
Coordinates of C are (0, 3) and the coordinates of C' are (0, -1).
This shows that C is rotated 180° about origin to get the new coordinates as (0, -3) and then new coordinates were dilated by 1/3 which forms C' as (0, -1)
Therefore option D is the correct option.
