Answer:
Step-by-step explanation:
Given that in a study of a weight loss program, 4 subjects lost an average of 48 lbs.
It is found that there is about a 32% chance of getting such results with a diet that has no effect.
The results do not appear to have statistical significance. The reasons are
1) Sample size of 4 is very small not even meeting the bare minimum
2) Sample of 4 cannot be taken to represent the population
3) Whether bias was there in the selection of sample is not known.
4) Std deviation is not considered which is very important while concluding results.
Answer:
each number in the ratio 4:5:7 is worth 6 sweets. add 4,5, and 7 to get 16 then multiply it by 6 to get 96 sweets.
Step-by-step explanation:
add the ratios = 4+5+7= 16
1 number = 6 so
4x6= 24
5x6=30
7x6=42
Frank gets 24 sweets
Mary gets 30 sweets
Seth gets 42 sweets
The total number of sweets they shared is 24+30+42= 96
The share 96 sweets altogether.
The check your answer; do 42-24= 18
Therefore, now we know that the difference between Seth and Frank's amount of sweets is 18.
Therefore, this is correct.
Answer:
P = x³ − 9x² + 36x − 54
Step-by-step explanation:
Complex roots come in conjugate pairs. So if 3−3i is a zero, then 3+3i is also a zero.
P = (x − 3) (x − (3−3i)) (x − (3+3i))
P = (x − 3) (x − 3 + 3i) (x − 3 − 3i)
P = (x − 3) ((x − 3)² − (3i)²)
P = (x − 3) ((x − 3)² + 9)
P = (x − 3)³ + 9 (x − 3)
P = x³ − 9x² + 27x − 27 + 9x − 27
P = x³ − 9x² + 36x − 54
Answer:

Step-by-step explanation:
2x +5y = 10
5y = - 2x + 10
y = - 2/5 x + 10
Equating it with y = mx + b
m = - 2/5
