A scientist is investigating whether percent concentration can be used to predict density in apple juice. A scientist selected a random sample of 12 apple juice varieties and recorded the density, in pounds per cubic inch, and the percent concentration of each apple juice variety. The scientist wants to estimate the mean change in the density, in pounds per cubic inch, for each increase of 1 percent concentration of apple juice
The most appropriate inference procedure for the given investigation is;
A linear regression t-interval for the slope
What is the inferential statistic?We are told that the slope of an horizontal line is zero and that there is no change in the y (dependent) variable when there is a change in the x-variable. Thus, we need to find the true relationship between the two variables, 'x', and 'y'.
The confidence interval of the slope is calculated and analyzed to find out if it excludes or includes, 0. Thus, if the confidence interval excludes 0, then, it is unlikely that the slope is 0 and therefore the relationship between the variables, 'x', and 'y' is significant
In conclusion, a linear regression t-interval for the slope is most appropriate inference procedure.

The formation of the silver(i) ammine complex ion is a reversible reaction that is allowed to reach equilibrium. For each subsequent change to the system, indicate how the concentration of each species in the chemical equation will change to reestablish equilibrium. An up arrow indicates an increase in concentration, a down arrow indicates a decrease in concentration, and leaving it blank means there is no change in the concentration
The equilibrium for the formation of silver(i) ammine complex ion is [Ag(H2O)6]^+(aq) + 6NH3(aq) ⇄ [Ag(NH3)6]^+(aq) + 6H2O(l).
What is equilibrium constant?The term equilibrium constant shows the extent to which reactants are converted into products. Recall that when the equilibrium is disturbed by a constraint, the system readjusts itself in order to annul the constraint.
The question is incomplete but the equilibrium for the formation of the silver(i) ammine complex ion is shown by;
[Ag(H2O)6]^+(aq) + 6NH3(aq) ⇄ [Ag(NH3)6]^+(aq) + 6H2O(l)

The five members of the traynor family each buy train tickets. During the train ride, each family member buys a boxed lunch for $6. 50. If the total cost of the trip is $248. 50, what is the price of each train ticket? enter your answer in the box
Answer:
Each ticket is $43.20
Explanation:
If there are five family members, and the meals are $.6.50 each, we will multiply $6.50 by 5.
$6.50 × 5= $32.5
Now we subtract the meals from the total of $248.50.
$248.50 - $32.5= $216
All five tickets cost $216, now we divide this by 5 since five tickets were bought.
[tex]\frac{216}{5}[/tex]= $43. 2
Each ticket was $43.20
Let's double-check:
$32.5 + $43.20(5)= $32.5 + $216= $248.50

A student performs an experiment in which two blocks, block x of mass 2kg and block y of mass 3kg, are tied together by a rope. The system containing block x and block y is dropped above earth’s surface in the orientation shown in figure 1. A motion detector below each block collected data that were graphed to show the velocity as a function of time for blocks x and y as they fell toward the ground. The graphs are shown in figure 2 and figure 3, respectively. The positive direction is considered to be down. The change in momentum for the system containing block x and block y is most nearly
The change in momentum for the system containing both blocks will be 250 kg m/s.
How to calculate the momentum?The momentum of an object simply means the product of the mass and the speed of the object.
In this case, the change in momentum will be:
P = (2 + 3)50
P = 5 × 50
P = 250 kg m/s
In conclusion, the change in momentum is 250 kg m/s.

If the volume occupied by the gas molecules shown below were doubled, what would happen to the pressure they exert? (assume constant temperature. )
In a gas molecule, If the volume occupied by the gas is doubled, the pressure of the gas exerted would also be doubled.
To approach this question, we need to understand the concept of Boyle's Law.
What is Boyle's Law?Boyle's Law states that at a constant temperature, the pressure of a gas varies inversely proportional to the volume of the gas. Thus, as the pressure of the gas decreases, the volume of the gas in the container also decreases, vice versa.
Mathematically;
[tex]\mathbf{=P \alpha \dfrac{1}{V}}[/tex]
PV = K
So, in a gas molecule, If the volume occupied by the gas is doubled, the pressure of the gas exerted would also be doubled.

The density of water is 1000 kilograms per cubic meter, and the density of ice is about 916 kilograms per cubic meter. If 575 kilograms of water and 275 kilograms of ice is combined in a container, about how much volume would the mixture take up?
Answer:
volume of the mixture is (0.575+0.300)-----> 0.875 m³
Explanation:
we know that
density=mass/volume--------> volume=mass/density
step 1
find the volume of water
mass=575 kg
density of water=1000 kg/m³
volume of water=mass/density-----> 575/1000----> 0.575 m³
step 2
find the volume of ice
mass=275 kg
density of ice=916 kg/m³
volume of ice=mass/density-----> 275/916----> 0.300... m³
the volume of water is 0.575³
the volume of ice is 0.300.. m³
volume of the mixture is (0.575+0.300)-----> 0.875 m³
