Explain the difference between an equation, like x=5, and an inequality, like x_> 5.
andrew11 [14]
X=5 is a definite answer and one solution. While X greater than OR equal to 5 means that it could be 5 AND anything above 5, which gives multiple of choices for solutions. (I believe this write but it’s been awhile since I did algebra stuff)

A horse race has 13 entries. Assuming that there are no ties, what is the probability that the four horses owned by one person f
Olin [163]
Well, there are 13 places that each horse can place. That means the first place has 13 options, second place has 12 options, third place has 11 options, etc. Though, we only care up to fourth place. When doing probability, we're multiplying in this case. So, here's the process:

How many ways all the horses can place = 13! = 6227020800
How many ways the first four places can place = 13*12*11*10 = 17160

Divide the second by the first and multiply by 100 for the probability as a percent:

(17160/6227020800)*100% ≈ <span>0.00027557319%

Answer:

\large\boxed{F_1=1,\ F_2=1}\\\boxed{F_n=F_{n-1}+F_{n-2},\qquad n\geq3}

Step-by-step explanation:

\text{The Fibonacci sequence:}\\\\1,\ 1,\ 2,\ 3,\ 5,\ 8,\ 13,\ 21,\ 34,\ 55,\ ....\\\\F_1=1\\F_2=1\\F_3=F_2+F_1\to F_3=1+1=2\\F_4=F_3+F_2\to F_4=2+1=3\\F_5=F_4+F_3\to F_5=3+2=5\\F_6=F_5+F_4\to F_6=5+3=8\\F_7=F_6+F_5\to F_7=8+5=13\\F_8=F_7+F_6\to F_8=13+8=21\\\vdots\\F_n=F_{n-1}+F_{n-2}

William has 24 cans of fruit and 60 cans of vegetables that he will be putting into bags for a food drive. He wants each bag to
nataly862011 [7]

Answer:

See explanation

Step-by-step explanation:

William has 24 cans of fruit and 60 cans of vegetables that he will be putting into bags for a food drive.

Factor number 24 and 60:

24=2\cdot 12=2\cdot 2\cdot 6=2\cdot 2\cdot 2\cdot 3=2^3\cdot 3\\ \\60=2\cdot 30=2\cdot 2\cdot 15=2\cdot 2\cdot 3\cdot 5=2^2\cdot 3\cdot 5

Find the greatest common factor

GCF(24,60)=2^2\cdot 3=12

Hence, the greatest number of bags William can make is 12.

Each of these bags will have 24\div 12=2 cans of fruit and 60\div 12=5 cans of vegetables.

If he made fewer bags, 6 bags, each of these bags will have 24\div 6=4 cans of fruit and 60\div 6=10 cans of vegetables.

If he made fewer bags, 4 bags, each of these bags will have 24\div 4=6 cans of fruit and 60\div 4=15 cans of vegetables.

If he made fewer bags, 3 bags, each of these bags will have 24\div 3=8 cans of fruit and 60\div 3=20 cans of vegetables.

If he made fewer bags, 2 bags, each of these bags will have 24\div 2=12 cans of fruit and 60\div 2=30 cans of vegetables.
