Has the marrying age of a man changed over the years? The United States Bureau of the Census takes a formal count of everyone in the U. S. every 10 years and has provided the following data that gives the median age of an
American man at the time of his first marriage.
Year 1910 1920 1930 1940 1950 1960 1970 1980 1990 2000
Median Age 25.124.6 24.3 24.3 22.8 22.8 23.2 24.7 26.126.8
What does a rate of change of zero mean in this situation?
a. The median age of a man at the time of his first marriage is, on the average, constant
b. The median age of a man at the time of his first marriage is, on the average, decreasing.
C. The median age of a man at the time of his first marriage is, on the average, increasing.
d. The rate of change cannot be zero in this situation.

rick has $1400 and sally has $1500

step-by-step explanation:

to find amount of money rick has after 10 years :

principal = $1000 , time = 10 years , rate = 4% annually

to find amount of money sally has after 10 years :

her friend gives to pay her $50 per year, therefore money she has after 10 years = 50 × 10 = $500

also, sally gets $1000 after 10 years,

therefore, total amount of money sally has after 10 years = 500 + 1000 = $1500

so, after 10 years : rick has $1400 and sally has $1500

34.5 cm

step-by-step explanation:

generally for a circular segment of angle, θ° and radius r

arc length

= (θ/360) x circumference

= (θ/360) x 2πr

in our case, θ = 60°, π=3.142 and r = 33 cm

substitute into above formula

arc length

= (60/360) x 2(3.142)( 33) = 34.5 cm

c

step-by-step explanation:

60

step-by-step explanation:

every triangle measures a total of 120 degrees. you have to find angle c. we know that isosceles triangles angles are equal. 60 degrees plus 60 degrees gives you 120.
