Answer:
YES
Step-by-step explanation:
1:4 can be written as:
, and we know to make and equivalent fraction you multiply by a constant. so,
×
=
(5:20)

IQR is the Q3 - Q1
Put the data in order.....
6, 7, 11, 13, 14, 15, 15, 19, 21
^ ^ ^
9(Q1) 14(Q2) 17(Q3)
17 (Q3) - 9 (Q1) = 8 (IQR)
So the answer to your question is the first option, 8.
Hope this helps! :D
Answer:
175lb
Step-by-step explanation:
Let's say 100% - original weight
and 12% - 21lb
weight = (100*21)/12=175lb
D.
slope = -3
passing thru(4,3)
y = mx + b
3 = -3(4) + b
b = 15
equation
y = -3x + 15
E.
(4,5)(6,9)
slope = (9-5)/(6-4) = 4/2 = 2
passing thru (4,5)(6,9)
y = mx + b
5 = 2(4) + b
b = -3
equation
y = 2x - 3
An=a1+d(n-1)
an=nth term
a1=first term, when n=1
d=common differnce=amount each term increases by
n=which one
so
when n=1, an=40
so a1=40
it seems to increas by 7 each time
an=40+7(n-1)
explicit formula is expanded
an=40+7n-7
an=33+7n is the formula
the domain is natural numbers because you can't have the -3rd term or the 0th term or the 3.24th term
domain is natural numbers
the formula is
