<h2>Answer:</h2>

The error interval for x is:

                  [3.65,3.74]

<h2>Step-by-step explanation:</h2>

The number after rounding off is obtained as:

                          3.7

We know that any of the number below on rounding off the number to the first decimal place will result in 3.7:

   3.65     3.66    3.67    3.68    3.69    3.70    3.71   3.72    3.73    3.74

( Because if we have to round off a number present in decimals to n place then if  there is a  number greater than or equal to 5 at n+1 place then it will result to the one higher digit  at nth place on rounding off and won't change the digit if it less than 5 )

         Hence, the error interval is:

             [3.65,3.74]

What is the percent of decrease from 500000 to 60000
DIA [1.3K]
Percent change = (new number - old number)/(old number) * 100

If the percent change is positive, it is a percent increase.
If the percent change is negative, it is a percent decrease.

In our case, the number goes from 500000 (the old number) to 60000 (the new number).

percent change = (new number - old number)/(old number) * 100

percent change = (60000 - 500000)/(500000) * 100

percent change = -88%

Answer: the percent decrease is 88%

Jillian is making accessories for the soccer team. She uses 677.46 inches of fabric on headbands for 38 players and 4 coaches. S
hodyreva [135]

The amount of fabric used to make the headband is 16.13 inches. The amount of fabric used to make the wristband is 9.64 inches.

In order to determine the amount of fabric used to make the accessories, the total inches used would be divided by the total number of people the accessory was made for.

The amount of fabric used to make headband for a player = total quantity of fabrics used / total number of people

677.46 / (38 + 4)

677.46 / 42

= 16.13 inches

The amount of fabric used to make wristband for a player = total quantity of fabrics used / total number of players

366.32 / 38 = 9.64 inches

Answer:

1. x = 27

2. c = 7

Step-by-step explanation:

-2x+51 = -3

-2x = -3-51

-2x = -54

x = -54/-2

x = 27

-2(c+19) = -52

c+19 = -52/-2

c+19 = 26

c = 26-19

c = 7
