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:
Step-by-step explanation:
∡x = v0t + 1/2 at²
∡x / v0t = 1/2 at²
2∡x / v0t =at²
a = 2∡x / v0t³
that's your answer:)
Answer:
b.$25.20
Step-by-step explanation:
Calculation for how much is the warranty
Using this formula
Warranty cost=Extended warranty purchase d price percentage*Purchased Price
Let plug in the formula

Step-by-step explanation:
a.
2(3x) - 5x = 4
6x - 5x = 4
x = 4
B. -5(x-4)+8x=29
-5x+20+8x=29
3x+20=29
3x=9
x=3
C. 2y=18+2(3-y)
2y=18+6-2y
2y=24-2y
4y=24
y=6
D. c = -b - 11
3c + 6 = 6b
3( -b - 11) +6 = 6b
-3b-33+6=6b
-3b-27=6b
-27=9b
3=b
17.4................add them up and divide by 10
