A number, x, rounded to 2 significant figures is 1300<br>Write down the error interval for x.​
nikitadnepr [17]

Answer:

[1250,1350).

Step-by-step explanation:

It is given that a number, x, rounded to 2 significant figures is 1300.

It is possible if,

1. The value of x is greater than of equal to 1250 and less than or equal to 1300.

i.e., 1250\leq x\leq 1300     ...(1)

2. The value of x is greater than of equal to 1300 and less than 1350.

i.e., 1300\leq x       ...(2)

On combining (1) and (2), we get

1250\leq x < 1350

1350 is not included in the error interval for x.​

Interval notation is [1250,1350).

Therefore, the error interval for x is [1250,1350).

Annalise invested $3,300 in an account paying an interest rate of 2.8% compounded monthly. Assuming
Artist 52 [7]

Answer:

  $4,881.56

Step-by-step explanation:

The future value formula is ...

  FV = P(1 +r/n)^(nt)

where principal P is invested at annual rate r compounded n times per year for t years.

You have P=3300, n=12, r=0.028, t=14, so the future value is ...

  FV = $3300(1 +0.028/12)^(12·14) = $4881.56

There would be $4881.56 in the account after 14 years.
