Answer:
difference in the proportion = 0.0452
Step-by-step explanation:
x1 = 27, n1 = 193,
p1 = 27/193
p1 = 0.1399
x2 = 16, n2 = 169,
p2 = 16/169
p2 = 0.0947
a) The best estimate for the difference in the proportion of smokers, using male proportion minus female proportion is 0.0452. Male smokes more than females in given sample.
p1 - p2 = 0.1399 - 0.0947
p1 - p2 = 0.0452
Answer:if you can't figure it out then just tell her you like her and see what she says. If she doesn't like you back then it's her loss

Answer:
slope = -
Step-by-step explanation:
Calculate the slope m using the slope formula
m = (y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁ ) = (3, 2) and (x₂, y₂ ) = (5, - 1)
m = = = -
Answer:
1,257 km
Step-by-step explanation:
The path of one satellite has the equation
This is the equation of the circle with the center at the origin (Eartg) and the radius of 7,500 km.
The orbit of the other satellite is 200 km farther from the centre of Earth, so the radius of this orbit is 7,700 km.
Find the distances travelled by two satellites:
1st satellite:
2nd satellite:
Difference:
