What is an example of a parameter in the study? The actual average percentage of conceptu 750 first-year students \( 34 \% \) of new but conceptually similar words 75 students

№3.2 По кругу расставлены девяносто горшков. В каждом из горшков сидит хотя бы одна лягушка, и в любых трёх стоящих подряд горшках суммарно сидит ровно четыре лягушки. Сколькими способами цапля Анастасия сможет выбрать два горшка так, чтобы в них суммарно оказалось ровно три лягушки?

Select the line that is equivalent to \( 2 x-3 y=9 \) \( y=\frac{2}{3} x-3 \) \( y=-\frac{3}{2} x+\frac{9}{2} \) \( y=-\frac{2}{3} x+3 \) \( y=\frac{3}{2} x-\frac{9}{2} \)

1) Odredi najmanji prirodni broj \( n \) za koji je \( 5^{n}>3126 \).

Travis has hired Charlie and Dora to plant flowers. Dora can plant 150 flowers in the same time it takes Charlie to plant 120 flowers, which can be shown using the following relationship where \( d \) and \( c \) are the respective rates (flowers per day) at which Dora and Charlie can plant flowers: \( \frac{150}{d}=\frac{120}{c} \) Also, Dora can plant 18 flowers more per day than Charlie. How many flowers can Charlie plant per day?

A line passes through the point \( (5,-11) \) and has slope of -2 . Find an equation of this line. \( y=-2 x-1 \) \( y=5 x-2 \) \( y=5 x-11 \) \( y=-2 x-11 \)
