Answer:

Isosceles Right Triangle Example

Step-by-step explanation:

Find the area and perimeter of an isosceles right triangle whose hypotenuse side is 10 cm. Therefore, the length of the congruent legs is 5√2 cm. Therefore, the perimeter of an isosceles right triangle is 24.14 cm.

Hope this answer helps ^^

Answer:

The demabd function is:

$q(p)= -4500p+18000$

Step-by-step explanation:

The demand follow the linear equation $q(p)=mp+b$

1. When p=$2.00 and q=9000, the equation is:

$9000=m(2.00)+b (1)$

2. Whe p=$4.00 and q=0, the equation is:

$0=m(4.00)+b (2)$

3. Solve equation (1) for b:

$9000=2m+b\\9000-2m=2m+2m+b\\9000-2m=b$

4. Replace the value of b in equation (2)

$0=4m+b\\0=4m+9000-2m\\0=2m+9000\\0-9000=2m+9000-9000\\-9000=2m\\\frac{-9000}{2m}=\frac{2m}{2m}\\ -4500=m$

The value of m is 4500

5. Calculate b, replacing m:

$0=4m+b\\\\0=4(-4500)+b\\0=-18000+b\\18000=b$

The value of b is 18000

Answer:

The 95% confidence interval for the percent of all black adults who would welcome a white person into their families is (0.8222, 0.8978).

Step-by-step explanation:

In a sample with a number n of people surveyed with a probability of a success of $\pi$ , and a confidence level of $1-\alpha$ , we have the following confidence interval of proportions.

$\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}$

In which

z is the zscore that has a pvalue of $1 - \frac{\alpha}{2}$ .

For this problem, we have that:

323 blacks, 86% of blacks said that they would welcome a white person into their families. This means that $n = 323, p = 0.86$

95% confidence level

So $\alpha = 0.05$ , z is the value of Z that has a pvalue of $1 - \frac{0.05}{2} = 0.975$ , so $Z = 1.96$ .

The lower limit of this interval is:

$\pi - z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.86 - 1.96\sqrt{\frac{0.86*0.14}{323}} = 0.8222$

The upper limit of this interval is:

$\pi + z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.86 + 1.96\sqrt{\frac{0.86*0.14}{323}} = 0.8978$

The 95% confidence interval for the percent of all black adults who would welcome a white person into their families is (0.8222, 0.8978).

The greatest number of bat bags the coach can buy with $605 is

Studentka2010 [4]

Answer:

11

12

does not

Step-by-step explanation:

If we know how much money the coach has and how much each bag costs we can find out how much bags the coach can by by divide the money the coach has by the price of one bat bag. So we do....

605 / 55 = 11

So now we know that she can by 11 bags maximum, while she needs 12 bags for the team. From this we know that she does not have enough money to buy 12 bags.
