3364
= 2^2 * 29^2
So
√3364 = √(2^2 * 29^2) = 2 * 29 = 58
The correct answer is : Rose cost is 2.1$,
carnation cost is 0.82$ and
tulip cost is 6.06$
Solution:-
Let rose cost be r$, carnation cost be c$ and tulip cost be t$.
Given 3 roses,2 carnations and 1 tulip costs 14$.
That is 3r+2c+t = 14, let it be first equation.
Also given 2 carnations and 6 tulips costs 38$.
That is 2c+6t=38
c+3t=19
c=19-3t
Also 1 rose, 12 carnations and 1 tulip costs 18$.
That is r+12c+t=18
Let us plugin c=19-3t in above equation.
r+12(19-3t)+t = 18
r=35t-210
Let us plugin r and c in first equation.
3(35t-210)+2(19-3t)+t =14
105t-630+38-6t+t =14
100t = 606
t=6.06$
c=19-3*6.06 = 0.82$
r=35*6.06-210=2.1$
Answer:
The experiment design used in this case is the between-subjected design.
Step-by-step explanation:
Between-subject design is a sort of experimental design where the individuals of an experiment are allocated to varied situations, with each individual being treated with only one of the experimental conditions.
In this case three similar ecosystems are designed containing a variety of insects and plants. Then each ecosystem to be exposed to rock music, country music, or a conventional city soundscape for two consecutive weeks.
Then after two weeks period they measured how successful the species were in each ecosystem.
The experiment design used in this case is the between-subjected design.
Answer:
y=-1.7x+8
Step-by-step explanation:
An equation of a line is y=mx+c
m is the gradient and c is the y intercept, which is where the line intercepts y.
you work out m getting two points and then subtracting y - y ÷ x - x
So in this graph, if we chose points (6,-2) and (3,3) then we would do this equation.
So m = -1.7
c = 8 because it goes through 8 in y.
So the equation is y=-1.7x+8
