2) The two lines are parallel       :Alternate Exterior Angles Converse

3) ∠3≅∠2                                      :Alternate Interior Angles Are Congruent

Answer:

statement         reasons

1=4                    given

1=2                    vertical angles

3=4                   congruent angles

therefore:       3=2

Step-by-step explanation:

Length of wood Samuel needs to build a fence = 346 feet

Length of each piece of wood = 15 feet

Number of wood pieces he will have with him :-

[tex] = \frac{346}{15} [/tex]

Samuel will need 23 pieces of wood .

Length of wood Theresa needs to build a fence :-

= 346 × 2

= 692 feet wood

Number of wood pieces Theresa will need :-

[tex] =\frac{692}{15} [/tex]

[tex] = 42 \: pieces \: of \: wood[/tex]

Therefore , Samuel needs 23 pieces of wood and Theresa needs 42 pieces of wood .

Answer:

The number of students to be sampled is [tex]n = 1789 [/tex]

Step-by-step explanation:

From the question we are told that

  The margin of error is  E = 0.03

Generally the proportion of students that receive financial aid is mathematically represented as  

          [tex]\^ p = \frac{118 }{200}[/tex]

=>        [tex]\^ p = 0.59[/tex]

From the question we are told the confidence level is  99% , hence the level of significance is    

      [tex]\alpha = (100 - 95 ) \%[/tex]

=>   [tex]\alpha = 0.05[/tex]

Generally from the normal distribution table the critical value  of  [tex]\frac{\alpha }{2}[/tex] is  

   [tex]Z_{\frac{\alpha }{2} } =  2.58 [/tex]

Generally the sample size is mathematically represented as

     [tex]n = [\frac{Z_{\frac{\alpha }{2} }}{E} ]^2 * \^ p (1 - \^ p ) [/tex]

=>  [tex]n = [\frac{2.58}{0.03} ]^2 * 0.59(1 - 0.59) [/tex]

=>  [tex]n = 1789 [/tex]

Using the margin of error, it is found that 1033 students would need to be sampled.

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]\alpha[/tex], we have the following confidence interval of proportions.

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

In which

The margin of error is of:

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

The dean randomly selects 200 students and finds that 118 of them are receiving financial aid, hence, the estimate is:

[tex]\pi = \frac{118}{200} = 0.59[/tex]

99% confidence level

So [tex]\alpha = 0.99[/tex], z is the value of Z that has a p-value of [tex]\frac{1+0.99}{2} = 0.995[/tex], so [tex]z = 2.575[/tex].  

The sample size needed is n when M = 0.03, hence:

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

[tex]0.03 = 1.96\sqrt{\frac{0.59(0.41)}{n}}[/tex]

[tex]0.03\sqrt{n} = 1.96\sqrt{0.59(0.41)}[/tex]

[tex]\sqrt{n} = \frac{1.96\sqrt{0.59(0.41)}}{0.03}[/tex]

[tex]\sqrt{n}^2 = \left(\frac{1.96\sqrt{0.59(0.41)}}{0.03}\right)^2[/tex]

[tex]n = 1032.5[/tex]

Rounding up, it is found that 1033 students would need to be sampled.

Answer:

Equation: $7 + $1.25t = $43.25

Solving:

$7 + $1.25t = $43.25

$1.25t = 36.25

$1.25t = 36.25

t = 29

So the answer is 29 minutes.

Answer:

15

Step-by-step explanation:

f(x)=6x-9

so nw x value give 4,

substitute x value with 4

f(4)=6(4)-9

=19

A function assigns the values. The value of the f(4) will be equal to 15.

A function assigns the value of each element of one set to the other specific element of another set.

For the given function f(x)=6x-9, therefore, the value of f(4) can be written as,

f(x) = 6x - 9

f(4) = 6(4) - 9

f(4) = 24 - 9 = 15

Hence, the value of the f(4) will be equal to 15.

Answer:

S^3+12

Step-by-step explanation:

The big block shows three s then you have to simplify that with 12ft^3

The expression that represents the total volume of the two storage spaces is s³+ 12

The total volume of the two storage spaces is the sum of the smaller storage space and the larger storage space.

Volume = width x height x length.

Volume of the larger storage space = s x s x s = s³

The total volume of the two storage spaces = s³+ 12
