"The grid shows Figure Q and its image Figure Q’ after a transformation. Which transformation was applied on Figure Q?

Mathematics
1 answer:
MA_775_DIABLO [31]3 years ago
8 0
The answer is C because if you turned Figure Q 90 degrees clockwise, it matches Q', thus a counterclockwise rotation of 270 degrees around the origin had to have been applied.

A is disqualified because if it had been rotated 90 degrees counterclockwise, it would be in the top left quadrant.

B is disqualified because if it was rotated 180 degrees about the origin, it would be in the bottom left quadrant.

D is disqualified because if rotated 270 degrees about the origin it would be in the top left quadrant, same as answer A.

A researcher reports a 98% confidence interval for the proportion of Drosophila in a population with mutation Adh-F to be [0.34,
Fantom [35]

Answer:

0.34 \leq p \leq 0.38

For this case we can conclude that with 98% of confidence the true proportion of Drosophila in a population would be between 0.34 and 0.38.

But that doesn't means that we have 98% of PROBABILITY that the true proportion would be between 0.34 and 0.38, because we are constructing a confidence interval with sample data and we can't analyze this using probability.

Then the best answer is:

2. False

Step-by-step explanation:

For this case we have a confidence interval for the proportion of Drosophila in a population with mutation Adh-F to be given by:

0.34 \leq p \leq 0.38

For this case we can conclude that with 98% of confidence the true proportion of Drosophila in a population would be between 0.34 and 0.38.

But that doesn't means that we have 98% of PROBABILITY that the true proportion would be between 0.34 and 0.38, because we are constructing a confidence interval with sample data and we can't analyze this using probability.

Then the best answer is:

2. False

The two triangles in the diagram are similar. There are two possible values of x. Work out each of these values. State ALL of yo
Simora [160]

Using the concept of proportional, it is found that the value of x  for the given similar triangles is 2.

<h3>What is a proportion?</h3>

A proportion is a fraction of a total amount, and the measures are related using a rule of three.

The relations between variables, either direct or inverse proportional, can be built to find the desired measures in the problem.

Since two triangles ΔACD and ΔABE are similar triangles, then their corresponding sides will be proportional.

Therefore, AC/ AB = AD / AE

By substituting the measures of the sides here;

AC/ AB = AD / AE

(x + 10) / 10 = (15 +3) / 15

15(x + 10) = 180

x + 10 = 12

x = 12 - 10

x = 2

Therefore, the value of x  for the given similar triangles is 2.
