Answer:A census
Step-by-step explanation:
Census is the collection of data from every member of a population. Parameter: A numerical measurement describing some characteristic of a population.
Answer:
a = 6
Step-by-step explanation:
(3.14 * 18) * 17.5 = 3.14 * (3a * 17.5)
3.14(3x * 17.5) = (3.14 * 18) * 17.5
3.14(3a * 17.5) = 3.14 * 18 * 17.5
3.14(3a * 17.5) = 989.1
3.14 * 3a * 17.5 * 100 = 989.1 * 100
16485a = 98910
a = 98910/16485
a = 6
the function y = 3 ( ½)^3
is an exponential function and the graph should be
decreasing because there is a fraction term in the expression, the graph should
be from a very large number to almost zero. The graph may be a or b
but it should not reach negative so the answer is b
Answer:
(5^2)(11^2)
Step-by-step explanation:
Taking all the factors in the left hand side of the factor tree, we have
5,5,11,11
5 twice
5^2=25
11 twice
11^2=121
The factor of 3,025=(5^2)(11^2)
Alternatively
3025÷5=605
605÷5=121
121÷11=11
11÷11=1
We have prime number 5 as divider twice and prime number 11 as a divider twice
Therefore,
5^2*11^2=3,025
Check
(5^2)(11^2)
=(25)(121)
=3,025
Answer:
He has 12 ten dollar bills
Step-by-step explanation:
Let t = number of 10 dollar bills
f = number of fifty dollar bills
t+f = 25 since he has 25 bills
solving for f
f = 25 -t
Then we know he has 770 dollars
10t+50f = 770
Using f = 25-t in the above equation
10t + 50 ( 25-t) = 770
Distribute
10t+ 1250 - 50t = 770
Combine like terms
-40t+1250 = 770
subtract 1250 from each side
-40t - 1250-1250 = 770-1250
-40t = -480
divide each side by -40
-40t/-40 = -480/-40
t =12
He has 12 ten dollar bills
