Data set A: 3,4,6,12,16,17,19

Mathematics
1 answer:
ASHA 777 [7]3 years ago
7 0

Answer: tbh Idk, but my bed answer would be C.

Step-by-step explanation:

On the online calculator, Desmos, I used these steps -

1. At The Top Left, there is a plus icon and in that icon I went down to table

2. Once the table was up, I entered the data and went to the next line under

3. At The Bottom Left, there is a keyboard icon and in that icon, over to the right, there is a functions button

4. Click the button and go over to STATS

5. Under stats, on the left and three down, you see "stdev", or standard deviation

6. Click that and in the parenthesis, if you didn't change the tables "x_1" and "y_1", use "x_1" (shift - underscore)

This gives you the stdev of DATA SET A

To get stdev of DATA SET B -

7. After getting stdev of DATA SET A, 6.633, go to the next line under and repeat steps 5&6, but replace "x_1" with "y_1".

(DATA SET B stdev is 1.290)

please help, i will give BRAINLIEST. Write an expression in the simplest form to model the perimeter of the following triangle:
HACTEHA [7]

Answer: Original expression:  2x - 11 + 4x + 7 + 3(x-4)

Simplified: 9x - 16

Step-by-step explanation:

2x - 11 + 4x + 7 + 3(x-4) becomes 2x - 11 + 4x + 7 + 3x -12

Group like terms, then combine to simplify:

2x + 4x + 3x -11 + 7 - 12

2x + 4x + 3x = 9x  

-11 -12 + 7 = =23+7= -16

Simplified expression: 9x  - 16

The perimeter of a rectangular field is 354 yards. If the width of the field is 82 yards, what is its length
GenaCL600 [577]
Length is 95 yards.

The perimeter of a rectangle is the sum of four sides. The four sides are either its length or width.

A rectangle has four sides where its angles are all right angles and its opposite sides are congruent or of equal size.

Perimeter = 2length + 2width ==> P = 2L   + 2W

354 = 2L + 2(82)
354 = 2L + 164
to get the length. we must transfer all like signs.
2L = 354 - 164
2L = 190
2L / 2 = 190 / 2
L = 95 yards.
