Step-by-step explanation: The mean of a data set is equal to the sum of the set of numbers divided by how many numbers are in the set. The mean is also commonly referred to as the average.

The median is the middle number in the data set when the data set is written from least to greatest. In other words, it's the middle of a specific list of numbers.

The mode is the number the appears most frequently in a data set. If there is no number that appears more often than another, we just say there is no mode.

The perimeter of a rectangular park is 300 feet. The length of the park is 50 feet longer than the width.

Answer:

85 feet

Step-by-step explanation:

P=2L+2W where L is the length and W is the width. If the length is 50 feet longer than the width, we can write the expression L=50+W. Substituting into P=2L+2W we get P=2(50+W)+2W=100+2W+2W=100+4W. Since P=300, we can say 300=100+4W. Subtracting 100 from each side we get 200=4W. Dividing each side by 4 gives 50=W. Substituting this into L=50+W gives L=50+35=85. The length is 85 feet.

I need help with questions 1,2, and 3. Would gratefully appreciate it (:

Answer:

Step-by-step explanation:

(2):

First let's organise the data:

33 miles ... x mph ... 4h - downstream

33 miles ... y mph ... 7h - up the stream

x = 33/4 = 8.25 mph

y = 33/7 = 4.71 mph

(3)

P(x) = $x^2 - 2x - 3$

To find the amount of key rings sold when the profit is 5000$ we have to equate P(x) with 5, because in the problem the profit of the key rings is displayed in terms of thousands.

$x^2 - 2x - 3 = 5\\x^2 - 2x - 8 = 0\\x_1 = 4, x_2 = -2$

Since the number of keyrings sold has to be positive the only answer is 4 thousand key rings.
