Answer: 108 pancakes
Step-by-step explanation:
if you make 20 pancakes with 1 and 2/3 of flour,
with 9 cups you will make
(20*9)/ 1 &2/3
1 2/3= 5/3 we enter the whole in the fraction
(180)/(5/3)= 180*3/5=108 pancakes
If we work it through:
70mph is 11mph less than 3 times the fastest running speed for a man.
So 70 + 11 = 81mph is 3 times the fastest running speed for a man.
Can you see where to go from here?
The mystery number will be 19.4596
Answer:
Step-by-step explanation:
Given that evolution theory hypothesizes that people should spontaneously follow a 24-hour cycle of sleeping and wakingdash–even if they are not exposed to the usual pattern of sunlight.
Sample size n = 8
df = 8- 1=7
Since population std deviation is not known, and sample size is small we can use only t test

(two tailed test at 5% level of significance)

sd 3.142857143
se 1.111167799
Test statistic = Mean diff/se = 1.595
p = 0.1546
since p >0.05, accept null hypothesis.
There is no evidence to prove that the steady cycle is different from 24 hours.
