Answer: 1008 revolutions
Step-by-step explanation:
1 revolution is equal to ![2\pi r](https://tex.z-dn.net/?f=2%5Cpi%20r)
To find how many revolutions the wheel makes, you must divide the distance traveled in the race between the circumference of the wheel
You must first convert 62.8318 in to meters.
We know that 1 inch is 0.0254 meters
Then
![62.8318\ in*\frac{0.0254\ m}{1\ in}= 1.5959\ m](https://tex.z-dn.net/?f=62.8318%5C%20in%2A%5Cfrac%7B0.0254%5C%20m%7D%7B1%5C%20in%7D%3D%201.5959%5C%20m)
![revolutions = \frac{1609}{1.5959}\\\\revolutions=1008.21\\](https://tex.z-dn.net/?f=revolutions%20%3D%20%5Cfrac%7B1609%7D%7B1.5959%7D%5C%5C%5C%5Crevolutions%3D1008.21%5C%5C)
Finally The wheel made 1008.21 revolutions

Step-by-step explanation:
none of these is equivalent to 6:10
Answer:
p-value: 0.453
Step-by-step explanation:
Hello!
You have two study variables
X~N(μₓ;σₓ²)
nₓ= 4
X[bar]ₓ= 149.50
Sₓ= 10.66
Y~N(μ
;σ
²)
= 6
X[bar]
= 158.17
S
= 19.87
The hypothesis is:
H₀: μₓ = μ![_{y}](https://tex.z-dn.net/?f=_%7By%7D)
H₁: μₓ ≠ μ![_{y}](https://tex.z-dn.net/?f=_%7By%7D)
The statistic to use is a pooled t for independent samples with unknown but equal population variances
t= [(X[bar]ₓ - X[bar]
) - (μₓ - μ
)]/[Sa/√(1/nₓ + 1/
)]
The value of the statistic is:
t= -0.789
For this statistic value the corresponding p-value is:
P(t ≤ -0.789) + (1 - P(t ≤ 0.789) = 0.453
I hope it helps!
