In a large population, 66 out of every 100 people like dogs better than cats. You would like to find out how likely it is a grou

p of cat-lovers from this population will come together by random chance. You decide to use a sampling distribution to help your analysis, and you believe that a sample size of 50 will be large enough to generate your data, so you select 50 people at random to participate in your study.
a) Using the information above, determine the probability of success - that is, the likelihood of an individual preferring cats - for the general population. Enter a number answer only. Round your answer to two decimal places.
b) Using the information above, determine the probability of failure - that is, the likelihood of an individual preferring dogs - for the general population. Enter a number answer only. Round your answer to two decimal places.
c) Using the information above, determine the sample size used in the study.
d) Using the information above, determine the mean of the sampling distribution for all samples of size 50. Enter a number answer only.
e) Using the information above, determine the standard deviation of the sampling distribution for all samples of size 50. Enter a number answer only. Round your answer to two decimal places.

OAA', OBB', and OCC' are straight lines. Triangle ABC is mapped onto Triangle A'B'C' by an enlargement with center O. What is th
bazaltina [42]

Answer:

(D) 2

Step-by-step explanation:

The scale factor of the enlargement of ΔABC to ΔA'B'C' is given by the ratio of the length of the corresponding sides of ΔA'B'C' and ΔABC

Therefore, we have;

The \ scale \ factor = \dfrac{Length \ of \overline  {B'C'}}{Length \ of \overline {BC}} =  \dfrac{Length \ of \overline  {A'C'}}{Length \ of \overline {AC}} =  \dfrac{Length \ of \overline  {A'B'}}{Length \ of \overline {AB}}

\dfrac{Length \ of \overline  {B'C'}}{Length \ of \overline {BC}} =  \dfrac{2 \ units}{1 \ unit} = 2

\dfrac{Length \ of \overline  {A'C'}}{Length \ of \overline {AC}} =  \dfrac{4 \ units}{2 \ units} = 2

\dfrac{Length \ of \overline  {A'B'}}{Length \ of \overline {AB}} =  \dfrac{2 \cdot \sqrt{5}  \ units}{\sqrt{5}  \ units} = 2

Therefore, the scale factor = 2

Can anyone help me out for this question? Please
MissTica
The answer would be H. All you have to do for a problem like this in the future are to add the 3 different angles together and make sure they equal 180 degrees.

Can i get some help with this
Olegator [25]

If we draw RU and RT we see the radii are perpendicular to the tangents, so TRU and TZU are supplementary. Since TZU=XZY=15 degrees, TRU=180-15=165 degrees. So the other side is 360-165=195 degrees as is the measure of arc TSU


Answer: 195 degrees
