Mr. Mendel likes breeding different flowers in his garden. He noticed that when he breeds a white flower with a purple flower, most of the offspring are purple. To check that, he bred them again and obtained 18181818 offspring, and 15151515 of them were purple. Let's test the hypothesis that the offspring have equal chances of 50%50\%50%50, percent of being either white or purple versus the alternative that the chance of a purple offspring is greater.
The table below sums up the results of 1000100010001000 simulations, each simulating 18181818 offspring with a 50%50\%50%50, percent chance of being white or purple.
According to the simulations, what is the probability of having 15151515 purple offspring or more out of 18181818?

Brittany has designed four different birdcages, each with the same volume: a square pyramid, a cylinder, a cone, and a sphere. the zoo wants to use one of brittany’s designs but plans to change the volume of the cage. find the design change that would result in the birdcage with the greatest volume. increase the area of the base of the square pyramid by a factor of ten. increase the height of the cylinder by a factor of ten. increase the radius of the cone by a factor of ten. increase the radius of a sphere by a factor of ten. juan wants to build a greenhouse in his back yard. he needs to maximize the ratio of floor area to structure volume in order to provide the most room for plants while minimizing the area to be heated. find the description of the structure that best meets juan’s criteria. a cube with a side length of 12 feet a cone with a diameter of 12 feet and a height of 10 feet a square pyramid with a base side length of 12 feet and a height of 9 feet a hemisphere with a diameter of 12 feet marion has a bicycle that she is planning to take for a ride. the rim of the rear wheel lies 41 cm from the center of the wheel. the tire itself has a thickness of 3 cm. in order to marion to ride her bicycle 96,712 cm, approximately how many rotations will the rear wheel make? 350 15.9 376 5133 an isosceles trapezoid has perimeter of 42 inches. each of the congruent nonparallel sides is 5 inches long, and the trapezoid is 3 inches tall. how long are the two parallel sides? 10 inches and 16 inches 12 inches and 20 inches 16 inches and 16 inches 10 inches and 22 inches

Can someone me i’m confused. will give brainliest and a whole bunch of points
