Answer:
5.25
Step-by-step explanation:
B. 1.67
m : n = 2 : 1
( x, y ) = ( (1*3 + 2*(-2))/(2+1) ; (1 * (-1) + 2 * 3) /(2 + 1) ) =
= ( (3-4)/3 ; (-1+6)/3 ) 1.67
The theoretical probability is what is expected based on using math. Since there is only one card that is number 1, and there are 400 possible outcomes, then the theoretical probability is 1/400 which is 0.25%.
Now find the experimental probability by find the number of times card 1 is picked, and the number of cards in total. 128/400 = 0.32 which is 32 percent.
The experimental probability is higher than the theoretical probability.
Hope this helps
I believe B or C but that’s a straight guess. i would say B just because if you live like outside of town then ur screwed
Answer:
32 daffodils bulbs and 28 crocus bulbs
Step-by-step explanation:
Assuming 'x' as Crocus and 'y' as daffodil. Now we'll form equations.
-> for 60 small flowering bulbs
x+y=60
x=60-y --->eq(1)
->Crocus bulbs cost $0.25 each and daffodil bulbs cost $0.65 each with the budget $27.80
0.25x + 0.65y = 27.80 -->eq(2)
Next is to substitute x=60-y in eq(2)
(2)=>0.25(60-y) + 0.65y = 27.80
15 - 0.25y + 0.65y = 27.80
0.4y = 12.8
y = 12.8/ 0.4
y= 32 daffodil bulbs
Now, plugging the value of y in eq(1)
(1)=>x=60-32
x= 28
x=28 crocus bulbs
Therefore, you can buy 32 daffodils bulbs and 28 crocus bulbs
