graph of the equation y = -5x + 10?
A. The graph would increase from left to right.
B. The graph would pass through the origin.
C. The graph would have a positive y-intercept.

Answer:

See below.

Step-by-step explanation:

  Statements:                                  Reasons:

1) ∠1≅∠4                                        :Given

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

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

Answer:

given: 1=4      prove: 3=2

statement         reasons

1=4                    given

1=2                    vertical angles

3=4                   congruent angles

therefore:       3=2

Step-by-step explanation:

Answer:

-2.5

Step-by-step explanation:

The slope of a line can be found by dividing the rise over the run between two points. The rise is the difference between the y-values, and the run is the difference between the x-values. For both, the value with the greater x-value comes first as you are seeing how much it has changed from the first value to the the other.

Let's use the first two points to find the slope: (0,9), (2,4)

(2,4) has the greater x-value, so the rise between the points would be -5, as 4 - 9 = -5

The run would be 2, as 2-0 = 2.

Therefore the slope would be: -5/2 = -2.5

Step-by-step explanation:

Let's see what to do buddy...

[tex] - 3(4 - 2x) = 4 - 2x[/tex]

Subtract the sides of the equation minus( 4 - 2x ) :

[tex] - 3(4 - 2x) - (4 - 2x) = 0[/tex]

Factoring ( 4 - 2x ) :

[tex](4 - 2x)( - 3 - 1) = 0[/tex]

[tex](4 - 2x)( - 4) = 0[/tex]

Divided the sides of the equation by -4

[tex]4 - 2x = 0[/tex]

Subtract the sides of the equation minus 4

[tex] - 2x = - 4[/tex]

Negatives simplified.

[tex]2x = 4[/tex]

Divided the sides of the equation by 2

[tex]x = \frac{4}{2} \\ [/tex]

[tex]x = 2[/tex]

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:

9,420 colors making exactly 1 car of each color exist

Step-by-step explanation:

Since there is no additional information, such as the number of colors we have to assume the maximum. Since there are over 10 million colors that exist and there is at least one car of each color, then there would be a maximum of 9,420 colors making exactly 1 car of each color exist. On the other end of the spectrum would be 2 colors making 4,710 cars of each color.

The number of different possible colors of vehicle can be found using the relation

Answer:

Explained below.

Step-by-step explanation:

The (1 - α)% confidence interval for the population mean is:

[tex]CI=\bar x\pm z_{\alpha/2}\times\frac{\sigma}{\sqrt{n}}[/tex]

The margin of error for this interval is:

[tex]MOE= z_{\alpha/2}\times\frac{\sigma}{\sqrt{n}}[/tex]

The factors affecting the MOE are:

Since the population standard deviation is not provided it is obvious the sample standard deviation is used to estimate the value of σ.

On increasing the value of σ the MOE will also increase.

As the sample size is inversely proportional, increasing the sample size by a factor of 4 will reduce the margin of error by half. But since σ is also increasing there are two factors affecting the MOE together.

Therefore reducing the MOE by more than half the original value.

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

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:

(a) 0.0000245

(b) 0.000025

Step-by-step explanation:

The complete question is:

Suppose that a computer chip company has just shipped 10,000 computer chips to a computer company. Unfortunately, 50 of the chips are defective. (a) Compute the probability that two randomly selected chips are defective using conditional probability. (b) There are 50 defective chips out of 10,000 shipped. The probability that the first chip randomly selected is defective is  50 /10,000  = 0.005.  Compute the probability that two randomly selected chips are defective under the assumption of independent events.

Solution:

(a)

In this case we need to compute the conditional probability of selecting two defective chips, i.e. the selection of the second defective chip is dependent on the first defective chip.

The probability of selecting the first defective chip is:

[tex]P(1D)=\frac{50}{10000}=0.005[/tex]

Now there are 9999 chips left and 49 defective chips among them.

The probability of selecting the second defective chip is:

[tex]P(2D)=\frac{49}{9999}=0.0049[/tex]

Compute the probability that two randomly selected chips are defective using conditional probability as follows:

P (Two defective chips) [tex]=P(1D)\times P(2D)=0.005\times 0.0049=0.0000245[/tex]

Thus, the answer is 0.0000245.

(b)

Compute the probability that two randomly selected chips are defective under the assumption of independent events as follows:

The above statement implies that the selection was done with replacement.

The probability is:

P (Two defective chips) [tex]=P(1D)\times P(2D)[/tex]

                                      [tex]=\frac{50}{10000}\times \frac{50}{10000}\\\\=0.005\times 0.005\\\\=0.000025[/tex]

Thus, the probability that two randomly selected chips are defective under the assumption of independent events is 0.000025.
