Juan did a survey in four butterfly parks and wrote the following observations: Butterfly Park Survey Park Number of Pink Butter

Elena L [17]

Answer:

Park Q has greatest percentage of pink butterflies.

Step-by-step explanation:

Butterfly Park Survey Park P Q R S

No, of Pink Butterflies 25 35 37 23

Total Number of Butterflies 53 64 75 55

Now we are supposed to find which park had the greatest percentage of pink butterflies

So, Percentage of pink butterflies in park P = $\frac{25}{53} \times 100=47.169\%$

Percentage of pink butterflies in park Q = $\frac{35}{64} \times 100=54.68\%$

Percentage of pink butterflies in park R= $\frac{37}{75} \times 100=49.33\%$

Percentage of pink butterflies in park S= $\frac{23}{55} \times 100=41.81\%$

So, Park Q has greatest percentage of pink butterflies.

So, Option B is true

Hence Park Q has greatest percentage of pink butterflies.

GIVING BRAINLIEST TO PERSON WHO GIVES CORRECT ANSWER TO THIS CONIC SECTIONS QUESTION

Alisiya [41]

Circle 1's center is at x=-4 and Circle 2's center is at x=5. To translate Circle 1 to Circle 2, we need to shift the circle to the right 9 places:

5 - (-4) = +9

We do the same thing for the y value. We are going from y=-2 to y=3.

3 - (-2) = +5

So the first blank is (9, 5)

Next, the scale factor refers to the factor at which the circle is stretched or shrunk. We find it by comparing the radii. Going from 3 cm to 6 cm, the scale factor is:

6/3 = 2.

The scale factor is 2.
