Round these numbers to the nearest tenth.<br> a) 74.3472<br> b) 98.759
Harman [31]

Answer:

a) 74.3

b) 98.8

Step-by-step explanation:

The tenth decimal place is the first place immediately to the right of the decimal point. When rounding, you first need to look at the number to the right of the place you wish to find. If the number in this spot is 5 - 9, round the number in the tenth decimal place up one unit. If the number is 0 - 4, keep the number in the tenth decimal place the same. Finally, remove all of the numbers to the right of the tenth decimal place.

a) 74.3472

        ^ tenth

The next number to the right (4) is not big enough to round up

a) 74.3

b) 98.759

         ^ tenth

The next number to the right (5) is big enough to round up

b) 98.8

Some track and field athletes feel that they are more likely to win a race if they start on the inside lane. The data above show
ivolga24 [154]

Answer:

D.]

Step-by-step explanation:

We will find the standard deviation and variance:

Variance= Ex^{2}-[[E(x)]^{2}

 E[x] = 3.462

E[{x}^2]= 31.86

Var(x)= 31.86-(3.462)^2 = 28.4

Standard deviation = \sqrt{Var(x)}

                               = \sqrt{28.4}

                               = 5.833 = 6(aproximately)

Therefore, the chances of winning are equal in each lane.
