When 258 college students are randomly selected and surveyed, it is found that 106 own a car. Find a 99% confidence interval for
juin [17]

Answer: 0.332 < p < 0.490

Step-by-step explanation:

We know that the confidence interval for population proportion is given by :-

\hat{p}\pm z^*\sqrt{\dfrac{\hat{p}(1-\hat{p})}{n}}

, where n= sample size

\hat{p} = sample proportion

z* = critical z-value.

As per given , we have

n= 258

Sample proportion of college students who own a car = \hat{p}=\dfrac{106}{258}\approx0.411

Critical z-value for 99% confidence interval is 2.576. (By z-table)

Therefore , the  99% confidence interval for the true proportion(p) of all college students who own a car will be :0.411\pm (2.576)\sqrt{\dfrac{0.411(1-0.411)}{258}}\\\\=0.411\pm (2.576)\sqrt{0.00093829}\\\\= 0.411\pm (2.576)(0.0306315197142)\\\\=0.411\pm 0.0789=(0.411-0.0789,\ 0.411+0.0789)\\\\=(0.3321,\ 0.4899)\approx(0.332,\ 0.490)

Hence, a 99% confidence interval for the true proportion of all college students who own a car : 0.332 < p < 0.490

Simplify negative 5 and 1 over 6 − negative 8 and 1 over 2
Tomtit [17]

Answer:

Hi there!

Your answer is;

17/6 <em><u>OR</u></em> 2 & 5/6

Step-by-step explanation:

(-5+1)/6 - (-8+1)/2

First, simplify in parentheses!

-4/6 - -7/2

Next, change the symbol of 7/2 because two negatives make a positive!

-4/6 +7/2

Next, change the denominators so they both have the same

-4/6 + 7/2

× 3/3

-4/6 + 21/6

Simplify!

17/6

<u>OR</u>

2 & 5/6

Hope this helps

Two adjacent sides of a parallelogram
saveliy_v [14]

Answer:

  6748'

Step-by-step explanation:

The long diagonal is the third leg of a triangle with the given side lengths and an angle between them that is the supplement of the given angle. Its length can be found from the Law of Cosines.

  a^2 = b^2 +c^2 -2bc·cos(A)

  a^2 = 3473^2 +4822^2 -2·3473·4822·cos(180° -72.23°)

  a^2 = 45,535,553.83

  a ≈ 6748.004

The longer diagonal is about 6758 feet long.

Why do you think it's important that we always label our units on word problems
MAXImum [283]
Word problems describe a situation where something mathematical can be found out about a system. Often, it's a real-world measurement (like numbers of apples, ages of people, inches, feet, etc.) and usually have more than one object being discussed. 
The answer must be expressed in specific units so the value cannot be confused with other measurements discussed in the problem.

2*cosx*(2x+30°) + √3=0
MAXImum [283]

Answer: x  ≈  1.59688927,  −1.60312387,  −4.67045686,  4.69039614,  7.872914,  −7.91513776,  −10.89002194

Step-by-step explanation:

Solve for  x  by simplifying both sides of the equation, then isolating the variable.

Simplify 2*cosx*(2x+30°) + √3=0

    Simplify each term.  

       Apply the distributive property.

  • 2  cos ( x )   ( 2 x )  + 2  cos ( x )  * 30 °  + √ 3 = 0
  • Multiply  2  by  2
  • 4  cos ( x )  x  +  2  cos ( x )  *30 ° + √ 3 = 0
  • Multiply  30 °by  2  
  • 4 cos ( x )  x  +  60 cos ( x ) + √ 3 = 0
  • Reorder factors in 4 cos ( x ) x + 60 cos ( x ) + √3
  • 4xcos(x)+60cos(x)+√3=0
  • Graph each side of the equation. The solution is the x-value of the point of intersection. x ≈ 1.59688927 , − 1.60312387 , − 4.67045686 , 4.69039614 , 7.872914 , − 7.91513776 , − 10.89002194
