Answer:
51.1 ≈ r
Step-by-step explanation:
"A bicycle wheel travels 321 in for each revolution"- means that 321 is the circumference of the wheel that is a circle.
C = 2· π· r
What is the radius of the wheel ?
321 = 2· π· r, divide both sides of the equation by 2 π
(321/2·π) = r , use calculator, solve and round the answer
51.1 ≈ r
Answer:
D. Since the P-value is less than 0.05, we reject the null hypothesis and conclude that there is a difference in the softness level achieved by the two processes.
Step-by-step explanation:
H0: μ1 - μ2 = 0
Ha: μ1 - μ2 ≠ 0
Test statistic t = 3.328, P-value = 0.0014, DF = 69.97
The Critical value for df = 69.97 is t ( ∝/2) (df): ±1.9945
The calculated t value falls in the critical region so H0 is rejected
As P - value is less than significance level H0 is rejected .
It is a two tailed test and the P - value is0.0014 which is less than 0.05 the significance level.
This means the softness achieved by Process A is considered to be not equal to the softness achieved by the Process-B .
Only choice D is correct.
Answer:
21,800
Step-by-step explanation:
Because 475 x 8 equals 3800 you add 3800 to 18,000 and get 21,800
We must set the two expressions to be equal:
216t + 18 = 362t + 8
Subtract 216t from both sides:
18 = 146t + 8
Subtract 8 from both sides:
10=146t
Divide both sides by 146:
t = 10/146 = 5/73
Bread:
Area = π R²
16 in² = π R²
R² = 16 in² / π
The radius of the bun = √(16 in² / π) = 2.257 inches
-- The meat :
Area = side²
16 in² = side²
Side = √16 in² = 4 inches
Diagonal of the square = 4 √2 = 5.657 inches
1/2 of the burgerdiagonal = 2.828 inches .
If the meat is centered on the bun, then the corner of the burger
extends
(2.828 - 2.257) = 0.57 inch
rounded to the nearest hundredth inch.
