Answer:
So, we conclude that the best estimate for the difference in the proportion of smokers is 4.4%.
Step-by-step explanation:
We know that 27 of the 193 males in the sample smoke while 16 of the 169 females in the sample smoke.
We have the following proportion:
So we get that 13.9% of men smoke.
We have the following proportion:
So we get that 9.5% of women smoke.
We get: 13.9%-9.5%=4.4%.
So, we conclude that the best estimate for the difference in the proportion of smokers is 4.4%.
Answer:
is the equal sign supposed to be there? if it wasnt then answer would be 42x^6y^11
Step-by-step explanation:
0.14 pounds (rounded; 0.135 unrounded); To calculate the % of something, divide it by 100 and multiply the result by the percentage you want to find.
0.0450 (=1%)
0.0450 x 3 = 0.135
Answer:
J. (2, -3)
Step-by-step explanation:
1. Substitute y = x - 5 in for y in the other equation:
5x + 2(x - 5) = 4
2. Simplify:
5x + 2x - 10 = 4 (distributed the 2)
7x - 10 = 4
3. Isolate for x:
7x - 10+10 = 4+10
7x = 14
7x/7 = 14/7
x = 2
4. Plug the new x value into an equation and solve for y:
y = 2 - 5
y = -3
hope this helps!
4 difference, subtract 20 point - 1st point, =19, 19 places x difference of 4= 76 more or less than 36. More would be 112, less would be -40.
A and C are both 40 while choice B = the difference so I'd say it's supposed to be 1 of the 40's but it's missing the negative sign
