Answer:
he is correct he might have seen it's 3 times more than 18-29 which is 10% so he just multiplied 45 with 3
Answer:
The point estimate for p is 0.86.
Step-by-step explanation:
We are given that in a marketing survey, a random sample of 730 women shoppers revealed that 628 remained loyal to their favorite supermarket during the past year (i.e. did not switch stores).
Let p = <u><em>proportion of all women shoppers who remain loyal to their favorite supermarket</em></u>
Now, the point estimate for the population proportion (p) is represented by ;
Point estimate for p =
=
where, X = Number of women shoppers who remained loyal to their favorite supermarket during the past year = 628
n = sample of women shoppers = 730
So, <u>point estimate for p</u> (
) =
=
= <u>0.86</u>
Answer:
The slope is 0.
Step-by-step explanation:
Distance formula= [(x2-x1)^2 + (y2-y1)^2]^1/2
Origin= white house = (0,0)
Capitol= (2300,800)
Put the value,
(2300² + 800² )^1/2
= 2435 meters
Thus distance is 2435 m
Answer:
14x - 6
Step-by-step explanation:
P = 2(length + width)
P = 2(6x - 2 + x - 1) = 2(7x - 3) = 14x - 6
