Answer:

n would have to be at least 16577

Step-by-step explanation:

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

[tex]\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]

In which

z is the zscore that has a pvalue of [tex]1 - \frac{\alpha}{2}[/tex].

The margin of error is:

[tex]M = z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]

Out of n randomly selected students he finds that that exactly half attend their home basketball games.

This means that [tex]\pi = 0.5[/tex]

99% confidence level

So [tex]\alpha = 0.01[/tex], z is the value of Z that has a pvalue of [tex]1 - \frac{0.01}{2} = 0.995[/tex], so [tex]Z = 2.575[/tex].

About how large would n have to be to get a margin of error less than 0.01 for p

A sample size of n is needed. n is found when M = 0.01. So

[tex]M = z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]

[tex]0.01 = 2.575\sqrt{\frac{0.5*0.5}{n}}[/tex]

[tex]0.01\sqrt{n} = 2.575*0.5[/tex]

[tex]\sqrt{n} = \frac{2.575*0.5}{0.01}[/tex]

[tex](\sqrt{n})^2 = (\frac{2.575*0.5}{0.01})^2[/tex]

[tex]n = 16576.6[/tex]

Rounding up

n would have to be at least 16577

When the error margin is smaller than 0.01, the value of n will be 16576.6.

The mean of your estimate plus and minus the range of that estimate constitutes a confidence interval.

Given that;

Confidence interval = 99 %

Randomly selected students,n

margin of error,M0.01

The margin of error for the given information is;

[tex]\rm M = z \frac{\sigma(1-\sigma)}{n} \\\\\ 0.01 = 2.575 \frac{0.5(0.5)}{n} \\\\ 0.01 \sqrt n = 2.575 \times 0.5 \\\\ \sqrt n = \frac{2.575 \times 0.5}{0.01} \\\\ n = 16576.6[/tex]

Hence, the value of n for which the margin of error is less than 0.01 will be 16576.6.

The correct statement which does not describe the data set is,

⇒  It has a range of 19.

The process of combining two or more numbers is called the Addition. The 4 main properties of addition are commutative, associative, distributive, and additive identity.

Given that;

A data set has these values:

⇒ 10, 12, 12, 14, 14, 14, 14, 16, 16, 18

Hence, We get;

Range = 18 - 10 = 9

Median = 10/2 + 1 term

            = 5 + 1 term

            = 6th term

Answer:

A. 390

Step-by-step explanation:

An exponential function can be written in the form [tex]f(n)=a\times b^n[/tex], where [tex]a[/tex] is your starting population, [tex]b[/tex] is the factor by which the population increases, and [tex]n[/tex] is the number of terms. In this case, [tex]a=740[/tex], [tex]b=0.88[/tex] because the population decreases by 12 percent (1-0.12=0.88), and [tex]n=5[/tex].

Thus, [tex]f(5)=740 \times 0.88^5[/tex], which is roughly equal to 390.

Answer:

63.5

Step-by-step explanation:

The diagonals of a rhombus bisect opposite angles.

The longer diagonal bisects the 42° angle

The larger angle of the rhombus is 180 - 42 = 138

Let x = the length of the longer diagonal

You know two sides and the included angle of a triangle.

Using the law of cosines we get

[tex]x^{2} = 34^{2} + 34^{2} -2(34)(34) cos 138\\ = 1156 + 1156 - 2312 cos 138\\ = 4030.150837...\\x = \sqrt{4030.150837} = 63.48[/tex][tex]x^{2} = 34^{2} + 34^{2} -2(34)(34)cos 138\\ = 1156 + 1156 - 2312 cos 138\\ = 4030.1508...\\ x = \sqrt{4030.1508} \\ = 63.48[/tex]x^2 = 34^2 + 34^2 - 2(34)(34) cos 138

      = 1156 + 1156 - 2312 c0s 138

      = 4030.1508...

x = sq rt 4030.1508...

Answer:

m<M= 85° m<N= 85°

Step-by-step explanation:

To find the value of x we should...

Sum of all angles = 360°

95+95+10x-5+8x+13 = 360

198+18x = 360

18x = 360-198

18x = 162

x = 162÷18

x = 9

m<M = (10×9)-5 = 90-5 = 85°

m<N = (8×9)+13 = 72+13 = 85°

PLZ pick me as brainliest

[tex]\(1/4\)[/tex] times 36 equals 9.

To find the value, x, that satisfies the equation [tex]\(\frac{1}{4} \times x = 9\)[/tex], you can solve for x as follows:

[tex]\[\frac{1}{4} \times x = 9\][/tex]

To isolate x, multiply both sides by [tex]\(\frac{4}{1}\)[/tex] (which is equivalent to multiplying by 4):

[tex]\[x = 9 \times 4\][/tex]

[tex]\[x = 36\][/tex]

So, [tex]\(1/4\)[/tex] times 36 equals 9.

Answer:   [tex]p \ \wedge \ q[/tex]

The upside down V symbol is known as a wedge. It represents a conjunction which is informally the "and". In other words, [tex]p \ \wedge \ q = \text{p and q}[/tex]

Note how we can replace p with "the taxes are high" and replace q with "the job pays well" to arrive at the overall compound statement "The taxes are high and the job pays well".

Some logic textbooks will use an ampersand symbol & to be used in place of a wedge. It will depend on the notation that they, or your teacher, has set up.
