Answer:answer will vary.
Step-by-step explanation:
Your teacher will display a graph of all the students’ sample proportions of heads.
The following is an example of a sampling distribution of sample proportion of head samples from 0.25 to 0.60
Since you are already given the formula for your arithmetic sequence you only gotta plug stuff in, and you have the following
Answer:
0.1d + 0.25q = 320
d + q + 4 = 2d ⇒ q + 4 = d (we can replace d in the above equation)
0.1(q + 4) + 0.25q = 320
0.1q + 0.4 + 0.25q = 320
0.35q = 319.6
q = 319.6 / 0.35 = 913.14 ≈ 913
0.25 x 913 = $228.25
0.10 x 917 = $91.70
total $319.95
there is not answer that will result in exactly $320
if Kelly has 914 quarters and 918 dimes = (914 x $0.25) + (918 x 0.10) = $320.30.
Answer:
rate of 6
Step-by-step explanation:
Answer:
7 3/10 hours or 7.3 hours
Step-by-step explanation:
We need to find two numbers that are multiples of 60 and close to 438
60*7 = 420
60*8 = 480
7<h<8
B. 438/60 = 7 18/60 = 7 3/10
