Two workers, a trainer and a trainee, working together can do a job in 3 hours. The trainer is 3 times faster than the trainee to complete the same job. How long will it take the trainee to finish the same job?
Answer:
4 hours
Step-by-step explanation:
Ratio of working together
Job : number of hours
1 : 3 = 1/3
Trainer
Job : number of hours
1 : x = 1/x
Trainee
Job : number of hours
1 : 3x = 1/3x
1/x + 1/3x = 1/3
Multiply through by 3x
3x(1/x) + 3x(1/3x) = 3x(1/3)
3 + 1 = x
4 = x
x = 4 hours
It takes the trainee 4 hours to finish the job

The probability of concluding that assignable variation exists when only random variation is present is:_____
I. the probability of a type I error.
II. known as the alpha risk
III. highly unlikely.
IV. the sum of probabilities in the two tails of the normal distribution
a. I and II
b. I and IV
c. II and III
d. I, II, and IV
e. I, III, and IV
Answer:
d. I, II, and IV
Step-by-step explanation:
The probability of a type I error: A type I error comes to play when one turns down the null hypothesis when it is true.
known as the alpha risk: this is also referred to as type I error, it is the risk in a statistical test which shows that a null hypothesis will be rejected even though it is actually true.
The sum of probabilities in the two tails of the normal distribution.
Hence, I, II, and IV are the options

Thomas went to the store to buy a couple of items for his mother at the store. He purchased a gallon
of milk for $2.15, a gallon of orange juice for $4.68, and a loaf of bread for $2.49.
If the sales tax is 8.25%, what is the total cost?
Answer:
$10.09
Step-by-step explanation:
2.49 + 2.15 + 4.68 = 9.32
9.32 * 0.825 = 0.77
9.32 + 0.77 = 10.09

Consider the system of equations below. What could be the first step in solving by elimination?
The first step would be to multiply the bottom equation by -1 to eliminate x, then you would combine like terms, like 5y + 2y, and 16 + 10.
Answer:
Subtracting the 2 equations
Step-by-step explanation:
3x + 5y = 16
3x + 2y = 10
Subtract it;
3y = 6
Divide both sides b 3;
y = 2
Substitute y;
3x + 5y = 16
3x + 5(2) = 16
3x + 10 = 16
Subtract 10 from both sides;
3x = 6
Divide both sides by 3;
x = 2
(x, y) = (2, 2)

Factor -6 out of 18z - 15
In mathematics, a factor is an integer or algebraic expression which divides another number or expression evenly, giving no remainder, and the further calculation can be defined as follows:
Given:
[tex]\bold{-6\ out \ of (18z - 15)}\\\\[/tex]
To find:
Factor=?
Solution:
[tex]\to \bold{-6\ out \ of (18z - 15)}\\\\\to \bold{-6\times \frac{(18z - 15)}{-6}}\\\\\to \bold{-6\ (-3z + \frac{5}{2})}}\\\\[/tex]
Therefore, the final answer is "[tex]\bold{-6\ (-3z + \frac{5}{2})}}[/tex]".

What is the length of the bedroom.
Answer:
[tex]10\sqrt{3}[/tex]
Step-by-step explanation:
The length of the bedroom would be [tex]4\sqrt{3}+ 6\sqrt{3}[/tex] which would equal [tex]10\sqrt{3}[/tex] because when 2 numbers have the same radical, you just add the number in front.
