Answer:

The value is [tex]n = 146093[/tex]

Step-by-step explanation:

From the question we are told that

    The margin of error is  [tex]E = 0.04[/tex]

   The data is  

      8.70      4.79    10.95   15.19    14.06

      16.99     1.22    9.02    14.39     5.73

      7.28     3.22     2.66    6.13       6.93

Generally the sample mean is mathematically represented as

    [tex]\= x = \frac{\sum x_i}{n}[/tex]

=>  [tex]\= x = \frac{ 8.70 + 4.79 +\cdots + 6.93}{15}[/tex]

=>  [tex]\= x = 8.48[/tex]

Generally the standard deviation is mathematically represented as  

       [tex]\sigma = \sqrt{ \frac{ \sum (x_i - \= x)}{n} }[/tex]

=>     [tex]\sigma = \sqrt{ \frac{ (8.70 - 8.48 )^2 + ( 8.70 - 8.48)^2 + \cdots + (6.93 - 8.48)^2 }{15} }[/tex]

=>     [tex]\sigma = 5.14[/tex]

From the question we are told the confidence level is  98% , hence the level of significance is    

      [tex]\alpha = (100 - 98 ) \%[/tex]

=>   [tex]\alpha = 0.02[/tex]

Generally the degree of freedom is mathematically represented as

      [tex]df = n -1[/tex]

=>   [tex]df = 15 -1[/tex]  

=>   [tex]df = 14[/tex]  

Generally from the t distribution table the critical value  of   at a degree of freedom of   is  

   [tex]t_{\frac{\alpha }{2} ,  14 } = 2.9768 [/tex]

Generally the sample size is mathematically represented as

      [tex]n =[ \frac{t_{\frac{\alpha }{2} , 14 } * \sigma }{E} ]^2[/tex]

=>    [tex]n =[ \frac{ 2.9768 * 5.136 }{0.04} ]^2[/tex]

=>    [tex]n = 146093[/tex]

Answer: 0.16

Step-by-step explanation:

Let X be a random variable that represents the heights of women at a large university are approximately bell-shaped, with a mean of 66 inches and standard deviation of 3 inches.

According to the Empirical Rule, for bell-shaped distributions, about 68% of the values fall within 1 standard deviation of the mean.

About 68% woman have height between ( 66-3) inches and (66+3) inches.

i.e. About 68% woman have height between 63 inches and 69 inches.

The percentage of woman have height either less than 69 inches or greater than 69 inches =100% - 68%= 32% [both share equal area on curve.]

The percentage of woman have height  is 69 inches or taller = 32%÷2

= 16%

Hence, the probability that a randomly selected woman from this university is 69 inches or taller =16%=0.16

Answer:

  x = -2 and x = 1/3

Step-by-step explanation:

The simple way to solve this is to enter the equation into a graphing calculator and have it show you what the zeros are.

The solutions are x = -2 and x = 1/3.

__

One way to solve this is to factor it. The product of the leading coefficient and the constant is (3)(-2) = -6. You want to find factors of this number that have a sum equal to the coefficient of the linear term: 5.

  -6 = (-1)(6) = (-2)(3) = ...

The first pair of factors listed here has a sum of 5, so we can rewrite the equation as ...

  3x^2 -x +6x -2 = 0

Factoring pairs of terms, we have ...

  x(3x -1) +2(3x -1) = 0

  (x +2)(3x -1) = 0

The solutions are the values of x that make these factors zero:

  x + 2 = 0   ⇒   x = -2

  3x -1 = 0   ⇒   x = 1/3

The solutions are x = -2 and x = 1/3.

Answer:

c = 33°, b = 147°

Step-by-step explanation:

You can just find that c + 147° makes a straight line (which is 180°) so c = 180° - 147°. You can do the same thing for b.

Answer:

P(X≤5) = 0.5105 (Approx)

Step-by-step explanation:

Assume, x = completion time of given task

Mean u = 7

So,

λ = 1/u = 1/7

So,

x ↔ exp(λ)

f(x) = P(X≤x) = [tex]1-e^{-\frac{1}{u}x }[/tex]

P(X≤5) = [tex]1-e^{-\frac{1}{7}5 }[/tex]

P(X≤5) = 0.5105 (Approx)

Answer:

Third choice 7(x + 2) - 3x = 2/3(6x + 3)

Step-by-step explanation:

Choice answer 1 has infinitely many solutions since -1/2(8x + 6) - 2x = -3(2x + 1) → -6x - 3 = -6x - 3 = 0 → 0 = 0 [is always equal to].

Choice answer 2 has one solution since

-1/2(8x + 6) - 2x = -3(2x + 1) → -2x - 8 = 2x - 8 → x = 0 [is equal to in 1 condition].

Choice answer 3 has no solution since

7(x + 2) - 3x = 2/3(6x + 3) → 4x + 14 = 4x + 2 → 0 = -12 [is never equal to].

Choice answer 4 has infinitely many solutions since -2x + 5 - 3x + 12 = -5(x - 3) + 2 → -5x + 17 = -5x + 17 → 0 = 0 [is always equal to].

The length of each side of the square is, 6 centimeter.

A rectangle is a two dimension figure with 4 sides, 4 corners and 4 right angles. The opposite sides of the rectangle are equal and parallel to each other.

We have to given that;

The area of a square is 36 square centimeters.

Now, We know that;

⇒ Area of square = Side²

Let the side of square = x

Hence, We can formulate;

⇒ x² = 36

⇒ x = √ 36

⇒ x = 6 centimeters
