Answer:

Angles RLN and KLM would be a linear pair.

Angles RLN and MLK would be vertical angles.

Vertical angles are formed when their sides share the same lines. RL shares the same line with LM and NL shares the same line with LK (see the attached diagram), so that means both angles form a vertical pair.

Metamorphic rock is formed when rocks or minerals are subjected to high heat and high pressure, or a combination of these two factors. Answer D is the only answer that explicitly describes a rock or mineral being subject to these two things, so therefore D is the best answer.

Answer:

9[tex]x^{2}y^{6}[/tex]

Step-by-step explanation:

There are three terms that need to be squared in this: -3, x, and y^3.

So, let's square all of them!

(-3) ^2=9

x^2=x^2

(y^3)^2=y^6

The answer   would be 9[tex]x^{2}y^{6}[/tex]

The 95% confidence interval is

    [tex]0.5055<  p <0.5725[/tex]

Step-by-step explanation:

From the question we are told that

  The sample size is  n =  850

  The number of can of people that will vote in a two people race is k =  458

Generally the sample proportion is mathematically represented as

        [tex]\^ p = \frac{k}{n}[/tex]

=>     [tex]\^ p = \frac{458}{850}[/tex]

=>     [tex]\^ p = 0.539[/tex]

From the question we are told the confidence level is  95% , 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   is  

   [tex]Z_{\frac{\alpha }{2} } =  1.96[/tex]

Generally the margin of error is mathematically represented as  

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

=>   [tex]E = 1.96 *  \sqrt{\frac{0.539(1- 0.539)}{850} } [/tex]

=>  [tex] E =  0.0335[/tex]

Generally 95% confidence interval is mathematically represented as  

             [tex]\r p -E <  p <  \r p +E[/tex]

=>          [tex] 0.539 - 0.0335<  p < 0.539 + 0.0335[/tex]

=>          [tex]0.5055<  p <0.5725[/tex]

Answer:

D. 3/4

Step-by-step explanation:

In order for the transformed line to be less steep than f(x), it must have an "a" value less than the slope of f(x). The slope of f(x) is 1, therefore, the only number less than 1 is 3/4.

Answer: The correct answer is c

Step-by-step explanation:

Graph C depicts an odd function.

We have the four graphs as shown in the figure.

We have to determine which graph depicts an odd function.

Assume a function f(x), if :  [tex]f(-x) = -f(x)[/tex] i.e., absolute value remains the same if the sign of the independent variable is reversed.

Remember - A function is called even if its graph is symmetrical about the y - axis, odd if its graph is symmetrical about the origin.

It can be seen that - Graph A, Graph B, Graph D are not symmetrical about the origin. Only Graph C - Sine wave is symmetrical about Origin.

Hence, Option C is the graph that depicts the odd function.

Answer:

it is 1.05

Step-by-step explanation:

The lightning was 1.7 kilometer away.

In unit time, the distance covered by any object is called speed.

In mathematical term, Speed is express as S=D/T,

where S=speed, D=distance, T= time.

Given that,

The speed of sound = 1225 kilometers per hour

The speed of sound = 340.277 meter/second

Also, the time after thunder heard = 5 seconds

To find distance, use formula distance = speed × time,

Distance = 340.277 × 5

               = 1701.3 meter

               = 1.7 kilometer

The lightning was 1.7 kilometer away.

Answer:

Company C has the lowes cost per tiger at $2.74. (Divide the prices by the number of stuffed animals, in this case, $41.10/15)

$2.26 would be their profit.

Step-by-step explanation:

To find how much money they have to pay for each stuffed animal, you have to divide the prices by the number that would be sold. For example, for Company C, it would be $41.10 divided by 15. When you do that with all the companies, you'll find the Company C is the cheapest.

You find their profit by subtracting $2.74 from $5. They sell it for $5, but they did have to use $2.74 to buy the stuffed animals. $5 - $2.74 = $2.26

Hope this helps! ^-^

Company C has the lowest cost per tiger.

Students will make a profit of $2.26 for each tiger sold.

The division is the process of dividing a number by a given number.

Note that company A offers 12 tigers for $33.24, therefore, divide 33.24 by 12 to get the cost of one tiger,

Cost of one tiger in company A = $33.24/12 = $2.77

Similarly,

The cost of one tiger in Company B = $44.80/16 = $2.8

The cost of one tiger in Company C = $41.10/15 = $2.74

Clearly, company C has the lowest cost per tiger.

Now, students will buy tigers from Company C for $2.74 per tiger and sell them for $5, therefore, the profit from selling one tiger will be 5-2.74=2.26.

Answer:

The confidence interval is [tex]0.15 < p < 0.19[/tex]

Step-by-step explanation:

From the question we are told that

  The sample proportion is  [tex]\^ p = 0.17[/tex]

  The margin of error is [tex]E = 0.02[/tex]

Generally the confidence interval  for the proportion of oil paintings that contained ultramarine blue is mathematically represented as

       [tex]\^ p - E < p < \^ p + E[/tex]

=>   [tex]0.17 - 0.02 < p < 0.17 + 0.02[/tex]

=>   [tex]0.15 < p < 0.19[/tex]

Answer: 0.1271

Step-by-step explanation:

Let p= probability of the students in a university are baseball players.

Given: p= 0.40 , sample size : n= 781

The probability that the sample proportion of baseball players will be greater than 43% will be:

[tex]P(p>0.43)=P(\dfrac{\hat{p}-p}{\sqrt{\dfrac{p(1-p)}{n}}}>\dfrac{0.43-0.41}{\sqrt{\dfrac{0.41(1-0.41)}{781}}}\\\\=P(Z>1.14)\ \ \ [Z=\dfrac{\hat{p}-p}{\sqrt{\dfrac{p(1-p)}{n}}}]\\\\=1-P(Z<1.14)\\\\=1- 0.8729=0.1271[/tex]

Hence, the probability that the sample proportion of baseball players will be greater than 43% = 0.1271
