A number, x, rounded to 1 decimal place is 3.7<br>Write down the error interval for x.​
alekssr [168]

Answer:

3.65 \leqslant x \leqslant 3.75

Step-by-step explanation:

The error in rounding a number is half of the unit of measure.

The number was rounded to the nearest 0.1 unit so the error is 1/2×0.1, which equals 0.05.

Now we add 3.7 and 0.05, which equals 3.75 and we also take 3.7 - 0.05, which equals 3.65

So, the error interval is:

3.65 \leqslant x \leqslant 3.75

Ai Lun, a management trainee at a large New York based bank, is trying to estimate the real rate of return expected by investors
salantis [7]

Answer:

option B

Step-by-step explanation:

given,                                              

3-month T-bill currently yields  = 3%          

customer price have been rising = 2% rate

Ai Lun's estimate of the real rate = ?            

real rate return                                                  

                       = \dfrac{1 + risk\ free\ rate}{1 +inflation\ rate} - 1

                       = \dfrac{1 + 0.03}{1 +0.02} - 1

                       = \dfrac{1.03}{1 .02} - 1

                       = 1.0098 - 1

                       = 0.0098

                       = 0.98 % ≅ 1 %

hence, the correct answer is option B

Answer:

A = 307.9 sq/cm

Step-by-step explanation:

Find the radius of the semi-circle

diameter + half the circumference = 72 cm

2r + pi*r = 72

r(2+pi) = 72

 

r = 72%2F%28%282%2Bpi%29%29

r = 14

:

what will be the area of that semicircle?

A =1%2F2*pi%2A14%5E2

A = 307.9 sq/cm
