The numbers a,b,c,d are four consecutive terms of an arithmetic sequence and a+b+c+d=12
likoan [24]

The smallest possible product of these four numbers is 59.0625

<h3>How to find the smallest possible product of these four numbers?</h3>

The equation is given as:

a + b + c + d = 12

The numbers are consecutive numbers.

So, we have:

a + a + 1 + a + 2 + a + 3 = 12

Evaluate the like terms

4a = 6

Divide by 4

a = 1.5

The smallest possible product of these four numbers is represented as:

Product = a * (a + 1) * (a + 2) * (a + 3)

This gives

Product = 1.5 * (1.5 + 1) * (1.5 + 2) * (1.5 + 3)

Evaluate

Product = 59.0625

Hence, the smallest possible product of these four numbers is 59.0625

Natalie is going mountain biking. She can buy a bike for $250 or she can rent a bike for $30 an hour.

In both cases, she must also rent a helmet for $5 an hour.

T = 30t.

Money required to purchase bike , M = $250.

For cost of buying a bike to be less than renting a bike :

30t>250\\\\t > \dfrac{25}{3}\ hours\\\\t>8\dfrac{1}{3}\ hours\\\\t>8\ hours \ 20 \ minutes

Hence, this is the required solution.

How to solve mean median and mode
cestrela7 [59]
You can solve the median by putting all the numbers in order. Then cross off one at a time at the start, then cross off the one at the end, then keep going until you get to one.

You can solve the mode by looking for the most frequent number. I remembered that by looking at mode and seeing MO and remembering most often.

I hope this helps :-)

What graph represents a function?
vredina [299]

Answer:

Bottom answer

Step-by-step explanation:

Although I cannot see the answer labels, the answer is the very bottom graph.  The way you can find a functional graph is if you add vertical lines going down and that there is only one point that crosses it, not two.  It is kind of difficult for me to explain, so if you need help, I suggest you look up how to know when a graph is a function or not.
