A rectangular field is 120 meters long and 75 meters wide.
Give the length and width of another rectangular field that has the same perimeter but a smaller area.
width = 0 meters
X
5
?
length =
meters

Step-by-step explanation:

l = 120 m ; b = 75 m

Perimeter = 2*(l+b) = 2*(120+75) = 2* 195 = 390 m

Area = l*b = 120*75 = 9000 sq.m

Another rectangular field:

length and width should be factor of 195 as both should have the same perimeter.

L = 190m ; b= 5m

Perimeter = 2*(190+5) = 2*195 = 390 m

Area = 190*5 = 950 sq.m

Same perimeter and a smaller area.

jacob, non hispanic white male. 30 years old.

probability that jacob lives to be 30 years old. 

since the given probabilities are probabilities of dying, i think we simply subtract it from 1 to get the probability of living. we will use the probability of non hispanic white male.

                                          probability of living to be 30 y.o.

29 - 30 : 1 - 0.001477 = 0.998523

30 - 31 : 1 - 0.001503 = 0.998497
