The following data show the height, in inches, of 11 different plants in a garden:
Andreas93 [3]

On average, the height of a plant varies 3.2 inches from the mean of 6 inches.

<h3>What does the mean absolute deviation represent? </h3>

An outlier is a number that is way smaller or way larger than that of other numbers in a data set. The outlier is 22.

Mean absolute deviation =  (1/n) x ∑ l x - m(x) l

Mean without the outlier : (9 + 4 +  10 + 9 + 5+  2 +  10 + 3 + 3+  5) / 10 = 6

(1/10) x ∑ l (9 - 6) + (4 - 6) +  (10 - 6)  + (9 - 6)  + (5 - 6) +  (2 - 6) +  (10 - 6)  + (3 - 6)  + (3 - 6) + ( 5 - 6) = 3.2

I just need the answer in word form
nadya68 [22]

Answer:

May 7, May 13, May 19

Step-by-step explanation:

Bethany wears jeans every two days. So, if she wears jeans on May 1, then she will wear jeans on May 3, May 5, May 7

Similarly, she wears running shoes every 3 days. So if she wears running shoes on May 1, then she will wear them on May 4 and May 7.

So she will wear both on May 7.

We can see a pattern that she wore both after six days of wearing them together first time.

Using the pattern we can say that she will again wear them both on May 13 and May 19th ..

Casey has 8 1 2 yards of fabric. She uses 2 1 2 yards to make pillows and 3 yards to make curtains. How much fabric is remaining
ra1l [238]

Let

x-------> yards of fabric used to make pillows

y-------> yards of fabric used to make curtains

T------> total yards of fabric

R-------> remaining yards of fabric

we know that

R=T-(x+y)

we have

T=8\frac{1}{2}\ yards\\\\ x= 2\frac{1}{2}\ yards\\ \\y=3\ yards

substitute in the formula above

R=8\frac{1}{2}-(2\frac{1}{2}+3)

R=8\frac{1}{2}-(5\frac{1}{2})

R=3\ yards

therefore

<u>the answer is</u>

the remaining of fabric is 3\ yards

Please help solve <br><br> 7 (x + 8) + 4 = -11 (x - 8) -9
Paladinen [302]

Answer:

x=1 1/18

Step-by-step explanation:

7(x+8)+4=-11(x-8)-9

distribute- 7x+56+4=-11x-88-9

7x+60=-11x+79

subtract 60 from both sides (60),(79)

7x=-11x+19

add 11x on both sides

18x/18 and 19/18

which gives you x=1 1/18 or 19/18
