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:

$27:x=193:100\%\\\\193x=27\cdot 100\\\\193x=2700\\\\x=\frac{2700}{193}\\\\x=13.9\%$

So we get that 13.9% of men smoke.

We have the following proportion:

$16:x=169:100\%\\\\169x=16\cdot 100\\\\169x=1600\\\\x=\frac{1600}{169}\\\\x=9.5\%$

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%.

Let f(x) = 3x2 - 6x + 2. Find f(-2)

Neporo4naja [7]

Answer:

just put

$x = - 2$

$f( x) = 3 {x}^{2} - 6x + 2$

$f( - 2) = 3 {( - 2)}^{2} - 6( - 2) + 2$

$f( - 2) = 3 \times 4 + 6 \times 2 + 2 =12+12+2 \\ f(-2)= 26$

Which table shows a proportional relationship

yKpoI14uk [10]

C, because as x increases y increases by a factor of 2. There is a constant value ( 2 ) which is being times to y in every value for x. So y is a constant multiple of x because x is always being multiplied by 2.
