Ok so I believe it’s 10.4 because first it’s

1.2 + 0.8 = 2
2 * 2 = 4
4 + 0.8 = 4.8
4.8 * 2 = 9.6

So 9.6 + 0.8 = 10.4

Answer:

19.2

Step-by-step explanation:

each element of the pattern is the product of the previous element and 2

1.2 x 2 = 2.4

2.4 x 2 = 4.8

4.8 x 2 = 9.6

therefore, the next number in the pattern would be the last element multiplied by 2

9.6 x 2 = 19.2

Mariana [72]

The equation for perimeter of rectangular garden is: 48=2(W+2W)

Step-by-step explanation:

Given

Perimeter = P = 48 yards

Let L be the length

and

W be the width

Also given

L = 2W

$P = 2(W+L)\\Putting\ L=2W and P =48\\48=2(W+2W)\\2W+4W=48\\6W=48\\W=\frac{48}{6}\\W=8\\L= 2W=2*16 =32\ yards$

The equation for perimeter of rectangular garden is: 48=2(W+2W)

Find the midpoint of the line segment joining the points R(3,2) and S(-5,5).

inessss [21]

The x coordinates are 3 and -5. They add to 3+(-5) = -2

Cut this in half to get -2/2 = -1

The x coordinate of the midpoint is x = -1

-------------------

The y coordinates are 2 and 5. They add to 2+5 = 7.

Then we cut this in half to get 7/2 = 3.5

The y coordinate of the midpoint is y = 3.5

-------------------

Overall, the midpoint is (-1, 3.5)

<h3>Answer: (-1, 3.5) which is the same as (-1, 7/2)</h3>

Put a lid on it! The supplier is considering two changes to reduce to 1% the

bija089 [108]

Answer:

A) 3.996 inches

B) 0.01

C) option B

Step-by-step explanation:

Note: The diameter of the lid is between : 3.95 and 4.05

A) calculate the supplier set mean diameter

std = 0.02 inch

P( x < 3.95 ) = 1% = 0.01

= P ( Z < $(\frac{3.95 - u }{0.02})$ ) = P ( Z < -2.3263 ) = 0.01

therefore :

$(\frac{3.95 - u }{0.02})$ = -2.3263

hence :<em> u </em>= 3.996 inches ( mean diameter )

B) At mean diameter = 3.98 calculate the value of std

P ( X < 3.95 ) = 0.01

= P ( Z < $( \frac{3.95-3.98 }{std } )$ ) = P ( Z < -2.3263 ) = 0.01

therefore

$( \frac{3.95-3.98 }{std } )$ = -2.3263

hence std = 0.01 inch

C) option B is preferable because its mean diameter is smaller and the percent of lids too large to fit is considered more carefully using option B
