Wheel A will travel a distance of approximately 9 in more than wheel B in one rotation.
<u>Explanation:</u>
Given:
Diameter of wheel A, d₁ = 25.4 in
Radius of wheel A, r₁ = 12.7 in
Diameter of wheel B = 22.5 in
Radius of Wheel B, d₂ = 11.25 in
Distance travelled by A = ?
In one rotation, the distance travelled by a wheel is equal to its circumference.
Circumference of a wheel = 2πr
Circumference of wheel A = 2πr₁
= 2 X 3.14 X 12.7 in
= 80 in
Circumference of wheel B = 2πr₂
= 2 X 3.14 X 11.25 in
= 71 in
Therefore, wheel A will travel a distance of approximately 9 (80 - 71 in) in more than wheel B in one rotation.
Answer:
The standard error is 0.02849
Step-by-step explanation:
<u>Explanation:</u>-
given data is 42% of primary case doctors think their patients receive un-necessary medical care.
That is The proportion 'p' = 42% = 0.42
Given sample size is n =300
The standard error of the sampling distribution of the sample proportion is
use calculator on simplification , we get
standard error = 0.02849
<span>Using the information we have
3x+4=40
Do the same to each side of the equation to eliminate for x.
3x+4=40 Minus 4 from each side
3x=40-4
3x=36
Divide 3 from each side
x=36/3
x=12
AC=3x+4
insert the value of x
3(12)+4=40
AC=40
AD=20</span>

➷ final = original x multiplier
final = 48 x 0.9
final = 43.2
Tony paid $43.20
Subtract the two values:
43.2 - 42.95 = 0.25
Therefore, the correct option would be C. Keith paid $0.25 less than Tony paid
