Answer:

1) Answer: 3)  ~~x = -3 \pm \sqrt{7}

2) Answer: 3) 2 and -6

Step-by-step explanation:

1)

(x + 3)^2 = 7

x + 3 = \pm \sqrt{7}

x = -3 \pm \sqrt{7}

Answer: 3)~~x = -3 \pm \sqrt{7}

2)

2(x + 2)^2 - 4 = 28

2(x + 2)^2 = 32

(x + 2)^2 = 16

x + 2 = \pm \sqrt{16}

x + 2 = \pm 4

x + 2 = 4   or   x + 2 = -4

x = 2   or   x = -6

Answer: x = 2 or x = -6

What is the Mean, Median, Mode, and Range for number 3<br><br> Please help
inysia [295]

Answer:

Mean: 49

Median: 41

Mode: 45

Range: 70

Step-by-step explanation:

To find the mean: add up all the numbers, then divide by how many numbers there are.

To find the median:

Arrange your numbers in numerical order.

Count how many numbers you have.

If you have an odd number, divide by 2 and round up to get the position of the median number.

If you have an even number, divide by 2. Go to the number in that position and average it with the number in the next higher position to get the median.

To find the mode: The mode of a data set is the number that occurs most frequently in the set.

To find the range: The range is the difference between the smallest and highest numbers in a list or set. To find the range, first put all the numbers in order. Then subtract (take away) the lowest number from the highest.
