Answer:

28

Step-by-step explanation:

A triangle always has 180° so that means 40° (2x+9)° and another angle add up to 180°.

We can find out two angles in order to find out the third, one of them is 40°  the other is 180°-105° because there are 180° on a line.

you get 75.

75°+40°=115°

180°-115°=65°

2x+9=65°

Make x the subject of the formula:

2x=56

(take away 9)

x=28

(divide both sides by 2)

scoundrel [369]

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 =  \hat p  =  \frac{X}{n}

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> (\hat p)  =  \frac{X}{n}  

                                             =  \frac{628}{730}  = <u>0.86</u>
