Once each day, darlene writes in her personal diary and records whether the sun is shining or not. when she looked back though her diary, she found that over a period of 600 days, the sun was shining 60% of the time. she kept recording for another 200 days and then found that the total number of sunny days dropped to 50%. how many of the final 200 days were sunny days?

For the following geometric sequence, find the recursive formula. {-80, 20, -5, } i need : ')

If 2(a^2+b^2)=(a+b)^2 then, > a+b=0, > ab=0, > a=b, > 2a=b

Kevin has a spinner that has 10 equal sections and 2 sections of each color—red, blue, green, yellow, and purple. kevin spins the spinner 180 times. kevin determines about how many times the spinner will land on red or green, and his work is shown below. -kevin has the formula reversed; it should be the total number of sections over the number of red or green sections. -kevin should have used a 4 in the numerator because there are 2 red sections and 2 green sections. -kevin should multiply by the number of sections in the spinner rather than the total number of spins. -kevin calculated the prediction correctly and did not make any mistakes.
