Answer:

TABLE 4 is the CORRECT REPRESENTATION.

Step-by-step explanation:

Two quantities P and Q is said to proportional to each other

⇔  P \propto Q  \implies   k  = \frac{Q}{P}

Here, k = PROPORTIONALITY CONSTANT

Now, in Table 1:

x = 2, y = 9 in first entry.

Here, k  = \frac{y}{x} = \frac{9}{2}  = 4.5\\\implies  k = 4.5

So, in Table 1 , the proportional relationship has a unit rate of 4.5.

Now, in Table 2:

x = 2, y = 6 in first entry.

Here, k  = \frac{y}{x} = \frac{6}{2}  = 3\\\implies  k = 3

So, in Table 2 , the proportional relationship has a unit rate of 3.

Now, in Table 3:

x = 2, y = 5 in first entry.

Here, k  = \frac{y}{x} = \frac{5}{2}  = 2.5\\\implies  k = 2.5

So, in Table 3 , the proportional relationship has a unit rate of 2.5.

Now, in Table 4:

x = 2, y = 7 in first entry.

Here, k  = \frac{y}{x} = \frac{7}{2}  = 3.5\\\implies  k = 3.5

So, in Table 4 , the proportional relationship has a unit rate of 3.5.

hence, TABLE 4 is the CORRECT REPRESENTATION.

Answer:

\text{C. }60

Step-by-step explanation:

<u>Question from image</u>:

"The digits 1, 2, 3, 4, and 5 can be formed to arrange 120 different numbers. How many of these numbers will have the digits 1 and 2 in increasing order? For example, 14352 and 51234 are two such numbers."

Let's start by taking a look with the number 1. There are four possible places 1 could be, because there needs to be space for the 2 after it.

Checkmarks mark where the 1 can be, the <em>x</em> marks where it cannot be.

\underline{\checkmark}\:\underline{\checkmark}\:\underline{\checkmark}\:\underline{\checkmark}\:\underline{X}

Let's start with the first position:

\underline{\checkmark}\:\underline{\#}\:\underline{\#}\:\underline{\#}\:\underline{\#}

There are four places the 2 can be. For each of these four places, we can arrange the remaining 3 digits in 3!=6 ways. Therefore, there are 4\cdot 6=\boxed{24} possible numbers when 1 is the first digit of the number.

Continue this process with the remaining possible positions for 1.

Second position:

\underline{X}\underline{\checkmark}\:\underline{\#}\:\underline{\#}\:\underline{\#}

There are three places the 2 can be, since the 2 must be behind the 1. For each of these three places, the remaining 3 digits can be arranged in 3!=6 ways. Therefore, there are 3\cdot 6=\boxed{18} possible numbers when 1 is the second digit of the number.

The pattern continues. Next there will be 2 places to place the 2. For each of these, there are 3!=6 ways to rearrange the remaining 3 digits for a total of 2\cdot 6=\boxed{12} possible numbers when 1 is the third digit of the number.

Lastly, when 1 is the fourth digit of the number, there is only 1 place the 2 can be. For this one place, there are still 3!=6 ways to rearrange the remaining three numbers. Therefore, there are 1\cdot 6=\boxed{6} possible numbers when 1 is the fourth digit of the number.

Thus, there are 24+18+12+6=\boxed{60} numbers that will have the digits 1 and 2 in increasing order, from a set of 120 five-digit numbers created by the digits 1 through 5, where no digit may be repeated.

How many numbers between 1 and 100 are multiples of both 2 and 7
liraira [26]
7. The formula is : 98-14=84 and then \frac{84}{14} and then 6+1=7.

The reason behind it is 14 is the least common multiple of 7 and 2 and 98 is the largest 2 digit multiple of 14. Subtract 98 and 14 and then divide by 14 to get 6 and then add 1. You will get 7 which is our answer!
