A 10-foot ladder is leaning against a tree. The bottom of the ladder is 4 feet away from the bottom of the tree. Approximately h
strojnjashka [21]

Answer:

C

Step-by-step explanation:

If we were to draw a horizontal line from the bottom of the ladder to the bottom of the tree and then draw a vertical line from the bottom of the tree to the top of the ladder, we'd get a right triangle with legs as the distance between the bottom of the tree and the bottom of the ladder and the height of the ladder, and the hypotenuse is the length.

Here, we know the hypotenuse is 10 feet and that the bottom of the ladder is 4 feet away from the bottom of the tree, so use the Pythagorean Theorem to find the height:

h = \sqrt{10^2-4^2} =\sqrt{84} ≈ 9.2 feet

The answer is C.

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>
