Answer:

  • B) 83.4 kilometers

Step-by-step explanation:

According to table we have units:

  • Kilo = 1000     ⇒ km = 1000 m
  • Milli = 0.001   ⇒  mm = 0.001 m

Comparing the two units we can see that:

  • 1  Km = 1000/0.001 = 1000000 mm

Then we can convert the distance in mm to Km:

  • 83400000 mm =
  • 83400000 / 1000000 km =
  • 83.4 km

Correct choice is B

the sitting height (from the bottom of the seat to the top of the person's head) of female drivers is normally distributed with
Sindrei [870]

Answer:

B; 50%

Step-by-step explanation:

Here, we want to calculate the percentage of women that will not fit in the driver’s seat

We proceed as follows;

We start with calculating the z-score of this;

That would be ;

(x-mean)/SD

in this case;

x = 34 inches

mean = 34 inches

SD = 1.4 inches

Thus, we have that;

(34-34)/1.4 = 0/1.4 = 0

when z-score is 0, we are at the center of the distribution

A z-score of 0 corresponds to exactly 50%
