Which are examples of unit rates?

Mathematics

Answers: Choice A and Choice C

Saying "$45 per ticket" is the same as saying "$45 for every single ticket" or "one ticket costs $45"

Similarly, "30 seats for every row" is equivalent to "each row has 30 seats"

-------------

choices B and D aren't unit rates because the second value mentioned isn't 1. You would have to divide to get to a unit rate. 
choice B: 5/3 = 1.67 so there are roughly 1.67 shows every week
choice D: 100/5 = 20 meaning its $20 per ticket

Answer:

To find the area of a triangle, multiply the base by the height, and then divide by 2. The division by 2 comes from the fact that a parallelogram can be divided into 2 triangles. For example, in the diagram to the left, the area of each triangle is equal to one-half the area of the parallelogram.

The projected T. rex is about
dolphi86 [110]

Answer: scale\ factor=230

Step-by-step explanation:

You need to analize all the information given in the exercise.

You know that the actual height of the T-rex on the projector lens is the following:

actual\ height=2\ cm

The height of the projected T-rex is:

projected\ height=4.6\ m

Make the conversion from meters to centimeters:

projected\ heigth=(4.6\ m)(\frac{100\ cm}{1\ m})\\\\projected\ heigth= 460\ cm

Therefore, the scale factor will be:

scale\ factor=\frac{projected\ heigth}{actual\ heigth}

Finally, you must substitute values into the equation and then you must evaluate in order to find the scale factor of the projection. You get that this is:

scale\ factor=\frac{460\ cm}{2\ cm}\\\\scale\ factor=230

Complete Question

Answer:

The null hypothesis is rejected this means that \mu \ne  0.5025

The 95% confidence interval is 0.5045608 <  \mu  < 0.5046392

Step-by-step explanation:

From the question we are told that

The standard deviation is s= 0.0001

The sample size is n = 25

The sample mean is \= x =  0.5046 \ in

The population mean is \mu  =  0.5025 \ in

The null hypothesis is H_o  :  \mu =  0.5025

The alternative hypothesis is H_a  :  \mu \ne  0.5025

The test statistics is mathematically represented as

t =  \frac{0.5046 -  0.5025}{ \frac{0.0001}{\sqrt{25} } }

t =  105

So the p-value from the z-table is mathematically represented as

p-value  =  2 *  P( z >  105)

p-value  = 0.000

seeing that

p-value <  \alpha we reject the null hypothesis

The critical value of

\frac{\alpha }{2} obtained from the normal distribution table is

Z_{\frac{\alpha }{2} } =  1.96

The margin of error is mathematically represented as

E = Z_{\frac{\alpha }{2} }*\frac{s}{\sqrt{n} }

=> E = 1.96 *\frac{0.0001}{\sqrt{25} }

=> E =3.92 *10^{-5}

The 95% confidence level is mathematically represented as

\= x  -  E  <  \mu  < \= x  + E

=> 0.5046  -  3.92 *10^{-5}  <  \mu  < 0.5046  +  3.92 *10^{-5}

=> 0.5045608 <  \mu  < 0.5046392
