Answer:

885.18

Step-by-step explanation:

Base = 18x18=324

triangles = 1/2(18)height

To find the height, you could divide it in half and use the 30-60-90 rule or Pythagorean theorem.

9²+b²=18²

81+b²=324

b²=324-81

b²=243

b=√243

b=15.58

So each triangle is 1/2(18)(15.58845)=140.2961.

Four of them would be 561.1845.

Now add the base.

561.1845+324=885.1844

In a study of 799 randomly selected medical malpractice​ lawsuits, it was found that 499 of them were dropped or dismissed. Use
Mademuasel [1]

Answer:

Claim is true that most medical malpractice lawsuits are dropped or dismissed.

Step-by-step explanation:

Given :In a study of 799 randomly selected medical malpractice​ lawsuits, it was found that 499 of them were dropped or dismissed.

To Find : Use a 0.05 significance level to test the claim that most medical malpractice lawsuits are dropped or dismissed.

Solution:

n =  799

x = 499

We will use one sample proportion test  

\widehat{p}=\frac{x}{n}\\\widehat{p}=\frac{499 }{ 799}\\\widehat{p}=0.6245

We are given that the claim is most medical malpractice lawsuits are dropped or dismissed.

Probability of dropped or dismissed is 1/2

 H_0:p=0.5\\H_a:p>0.5

Formula of test statistic = \frac{\widehat{p}-p}{\sqrt{\frac{p(1-p)}{n}}}

                                        =\frac{0.6245-0.5}{\sqrt{\frac{0.5(1-0.5)}{799}}}

                                       = 7.038

p value (z>7.038) is 0

α =0.05

So, p value < α

So, we reject the null hypothesis

So,claim is true

Hence most medical malpractice lawsuits are dropped or dismissed.

Please help me with this show me the steps please
alisha [4.7K]

Answer:

The objective for solving equations for variables is to get the x terms on one side and the non-x terms on the other side.

7) r + sx = t

sx = t - r (Subtract r from both sides)

x = (t - r) / s (Divide both sides by s)

8) m = 2x + n

m - n = 2x (Subtract n from both sides)

(m - n) / 2 = x (Divide both sides by 2)

x = (m - n) / 2 ("Flip" the equation, this is optional but this is how you usually write your answer, it will be in the form x = something.)

9) 4x - 5c = 3c

4x = 8c (Add 5c to both sides; 5c + 3c = 8c)

x = 2c (Divide both sides by 4; 8c / 4 = 2c)
