We know that:
15 customers = 1per hour how
X = 8 hours
Then
= 15 x 8 hours
= 120 customers

Researchers used two footballs of the same size to examine the effect of helium on kicking distance. one football was filled with air, and the other was filled with helium. eleven people participated in the study. each person kicked the football filled with air and the football filled with helium, and the kicking distances, in yards, were recorded. the football that was kicked first was determined by the flip of a fair coin, and the people did not know which football was filled with air and which was filled with helium. what type of study was conducted by the researchers and, of the following, which is the appropriate t-interval for inference?
The appropriate t-interval for inference is a t-interval for a difference between means for independent samples.
What is T interval known for?T interval is known to be used in any given situations where the given sample size is known to be little and population standard deviation is said to be not known.

What is the molar solubility of agcl (ksp = 1.80 × 10⁻¹⁰) in 0.500 m nh₃? (kf of ag(nh₃)₂⁺ is 1.7 × 10⁷)
Based on the Ksp calculations, the molar solubility of AgCl in 0.500 M of NH₃ is equal to 2.77 × 10⁻² M.
How to determine the molar solubility.First of al, we would write the properly balanced chemical equation for this chemical reaction:
AgCl(s) ⇆ Ag⁺(aq)+ Cl⁻(aq) Ksp = 1.8 × 10⁻¹⁰
AgCl(s) + 2NH₃(aq) ⇆ Ag(NH₃)₂⁺(aq) Kf = 1. 7 × 10⁷
Given the following data:
Ksp of AgCl = 1.8 × 10⁻¹⁰Concentration of NH₃ = 0.500Kf of ag(nh₃)₂⁺ = 1.7 × 10⁷K = Ksp × Kf
K = 1. 80 × 10⁻¹⁰ × 1.7 × 10⁷
K = 3.06 × 10⁻³
Mathematically, the Ksp for the above chemical reaction is given by:
[tex]K=\frac{ [Ag(NH_3)_2^{+}][Cl]}{[NH_3]^2}\\\\3.06 \times 10^{-3}=\frac{[x][x]}{0.50^{2 }}\\\\3.06 \times 10^{-3}=\frac{x^2}{0.25}\\\\x^2 = 7.65\times 10^{-4}\\\\x=\sqrt{7.65\times 10^{-4}}[/tex]
x = 2.77 × 10⁻² M.

A bicycle wheel is mounted on a fixed, frictionless axle, with a light string wound around its rim. The wheel has moment of inertia i=kmr2, where m is its mass, r is its radius, and k is a dimensionless constant between zero and one. The wheel is rotating counterclockwise with angular speed ω0, when at time t=0 someone starts pulling the string with a force of magnitude f. Assume that the string does not slip on the wheel
The final rotational speed ω_final and the instantaneous power P delivered to the wheel are; ω_f = √((ω_i)² + 2(FL/(kmr²) and P = Frω_i
What is the Instantaneous Power?A) From rotational kinematics, the formula for the final angular velocity is;
ω_f = √((ω_i)² + 2αθ)
where;
α is angular acceleration
θ = L/r. Thus;
ω_f = √((ω_i)² + 2α(L/r))
Now, α = T/I
Where;
I is moment of inertia = k*m*r²
T is t o r q u e = F * r
Thus;
α = (F * r)/(kmr²)
α = F/(kmr)
ω_f = √((ω_i)² + 2(F/(kmr))(L/r))
ω_f = √((ω_i)² + 2(FL/(kmr²)
B) Formula for instantaneous power is;
P = Fv

Enter an equation showing how this buffer neutralizes added aqueous base (csoh).
Answer:
Here, the buffer is NH₄Cl + NH₃
The strong base is added to the buffer solution, then the salt reacts with the base to form a weak base and water, which does not alter the pH
NH₄Cl + CsOH → NH₃ + CsCl + H₂O
NH₄⁺ + OH⁻ → NH₃ + H₂O
When we add strong acid to the buffer solution, the base NH₃ reacts with acid and forms salt, which does not alter the pH
NH₃ + H⁺ → NH₄⁺
