Answer:

3/5

Step-by-step explanation:

The range of the cosine function is [-1, 1]. Since √41/5 is greater than 1, we eliminate answers a) and b) immediately.

If this angle lies in Quadrant IV, the "adjacent side" is positive. Thus, the cosine of this angle must be 3/5.

After calculating the sample size needed to estimate a population proportion to within 0.05, you have been told that the maximum

Svetlanka [38]

Answer: 40000

Step-by-step explanation:

The formula to find the sample size is given by :-

$n=p(1-p)(\dfrac{z_{\alpha/2}}{E})^2$ , where p is the prior estimate of the population proportion.

Here we can see that the sample size is inversely proportion withe square of margin of error.

i.e. $n\ \alpha\ \dfrac{1}{E^2}$

By the equation inverse variation, we have

$n_1E_1^2=n_2E_2^2$

Given : $E_1=0.05$ $n_1=1000$

$E_2=0.025$

Then, we have

$(1000)(0.05)^2=n_2(0.025)^2\\\\\Rightarrow\ 2.5=0.000625n_2\\\\\Rightarrow\ n_2=\dfrac{2.5}{0.000625}=4000$

Hence, the sample size will now have to be 4000.

Answer:

Yvette cleared 10 large driveways

Step-by-step explanation:

small driveway = x

big driveway = y

x+y = 25

15x + 25y = 475

y = 25-x

15x + 25(25-x) = 475

-10x + 625 = 475

10x = 150

x= 15

15 + y = 25

y =10

10 large driveways, 1 5 small driveways

Step-by-step explanation:

Longest side is between 36 and 18 feet

18 < L < 36

IF longest side were 36 feet, width =0

IF longest side were 18, then width = 18

to be longest L>W L>18. and L can't be as much as 36 to keep width >0
