|2x - 5| - 2 = 3 |add 2 to both sides
|2x - 5| = 5
2x - 5 = 5 or 2x - 5 = -5 |add 5 to both sides
2x = 10 or 2x = 0 |divide both sides by 2
x = 5 or x = 0
All steps are correct.
Let
x = 2.131313... Equation 1
Multiply both sides by 100 to get:
100x = 213.131313... Equation 2
Subtract equation 1 from equation 2.
99x = 211
x = 211/99
Answer: 211/99
Answer:
4 gallon
Step-by-step explanation:
Gallon jug of Milk used every 3 days = 12
To. Obtain the rate of milk consumption :
Gallon of milk consumed per day :
Total gallon jug of milk / Number of days
12 / 3
= 4 gallon jug
Hence, the Harper family consumes 4 gallon jug of milk per day.
Step-by-step explanation
The answers in bold is what was required from the question.
the null hypothesis using symbol:-
H₀ : μ = 11.80
the alternative hypothesis using symbol:-
H₁: μ ≠ 11.80
This is a one tailed test. Given what you know, you will evaluate this hypothesis using a t test statistic.
Alpha level = 0.05
Sample size = n
Degree of freedom = n-1 = 40-1 = 39
To use the t distribution we will have to find the critical value from the t table this value is 1.685
But the question does not have sample mean and sample standard deviation. So I was unable to solve for the standard error
