Answer:
Probability of choosing green and yellow treat is higher than Probability of choosing an orange and yellow treat by 0.08
Step-by-step explanation:
Given -
Green and yellow gummy treats = 20
Red and yellow gummy treats = 14
Orange and yellow gummy treats = 16
Total gummy treat = 20+14+16 = 50
Probability of choosing green and yellow treat = 20/50 = 0.4
Probability of choosing an orange and yellow treat = 16/50 = 0.32
Probability of choosing green and yellow treat is higher than Probability of choosing an orange and yellow treat by 0.08

Answer:
C: left tailed
Step-by-step explanation:
In two tailed hypothesis, the alternative hypothesis is when mean can either be lesser or greater than the given value. Usually uses the symbol ≠.
In right tailed, the alternative hypothesis is when the mean is greater than the given value.
In left tailed, the alternative hypothesis is when the mean is lesser than the given value.
In this question, the hypothesis test to be performed is to determine if the average amount of time spent watching television per week has decreased from the given value of 21.6 hours.
Thus, it is left tailed test.
Answer:
g(x) = x^4 - 3x^3 - x^2 - 27x -90
Step-by-step explanation:
Answer:
The work has Been done is 2503.12 J .
Step-by-step explanation:
Formula for workdone is given by
Workdone = Force × Distance
As w = mg
Where m is the mass , g is the acceleration of gravity .
As given
Ben Pumpiniron applies an upward force to lift a 129-kg barbell to a height of 1.98 m at a constant speed.
m = 129 kg
g = 9.8 m / s²
Putting in the w =mg
w = 129 × 9.8
= 1264.2 kg m / s²
(As given in the question force is constant thus force doing the work is equal to weight .)
Thus
Force = 1264.2 kg m / s²
Workdone = Force × Distance
= 1264.2 × 1.98
= 2503.12 J (Approx)
Therefore the work has Been done is 2503.12 J .
