1. Okay, we're looking at this list, and we need to find the mathematical mean, median, and modes of this list.

Median = The value closest to the middle of the set.

17, 18, 18, 19, 20, 21, 21, 21, 22, 22, 22, 22, 23, 25, 26

If we count, there are 15 values, so we just have to find the middle one, which is 21

The median of the first problem is 21.

Mode = The number that occurs most frequently in the set. In this set, we can see that the number 22 appears 4 times, which is more than any other number in the set.

22 is the mode for the first problem.

Range = The distance in numeric value between the highest number of the set and the lowest number. 

26 is the highest number and 17 is the lowest.

26 - 17 = 9

The range of the first problem is 9.

2.  We solve for average by adding all values together and then dividing by the amount of values there are.

(17 + (18 * 2) + 19 + 20 + (21 * 3) + (22 * 4) + 23 + 25 + 26) / 15 = 21.13... = 21 \frac{2}{15}

<span>The average amount of grain needed is 21 \frac{2}{15}

3. For this one, we just have to solve it the same way, and then compare the central measures.

Median = 21 (For this one, there was an even amount of numbers, so we just took the average of the two closest to the middle, both of which were 21. The average of two numbers of the same value is that same number)

Mode = 22

Range = 9

The three values have not changed from the original values, so there is no change.

Hope that helped =)</span>

The city zoo has different admission prices for adults and children. When three adults and two children went to the zoo, the bil
charle [14.2K]

Answer:

The price of adult's ticket is $ 17.73     And

The price of children's ticket is $ 13.85

Step-by-step explanation:

Given as :

The Prices for adult ticket and child ticket in the city zoo is different

Let the price for adult's ticket = $ A

And The price for child's ticket = $ C

Now, according to question :

3 A + 2 C = $ 80.89        And

2 A + 3 C = $ 77.01

Now solve the both equation

So, 2 × (3 A + 2 C) = 2 × $ 80.89      And

     3 ×  (2 A + 3 C) = 3 × $ 77.01

I.e

      6 A + 4 C = $ 161.78        And

      6 A + 9 C = $ 231.03

Now, ( 6 A + 9 C ) - ( 6 A + 4 C ) = $ 231.03 -  $ 161.78  

Or,      5 C = $ 69.25

Or,         C = $ 13.85

And Put the value of C in above any eq

       6 A + 4 × ($ 13.85) = $ 161.78

Or,   6 A = $ 161.78 - $ 55.4

Or,   6 A = $ 106.38

∴         A = \frac{106.38}{6}

Or,     A = $ 17.73

Hence The price of adult's ticket is $ 17.73     And

            The price of children's ticket is $ 13.85    Answer

bulgar [2K]

Answer:

Step-by-step explanation:

Dimensions of the backyard is 14 m by 15 m

<u>The length of the fence is the perimeter of the backyard.</u>

  • P = 2(l +w)
  • P = 2(15 + 14) = 2(29) = 58 m

One meter of the fence costs $6.63

<u>Cost of the entire fence is:</u>

  • 58*$6.63 = $384.54

Find the value of x picture attached
aev [14]

Answer:

<em>x = 10</em>

Step-by-step explanation:

These angles are <em>same side interior angles</em>.

This means that (11x + 10) + (10x - 40) = 180

Solve for x:

11x + 10 + 10x - 40 = 180

21x - 30 = 180

      +30     +30

21x = 210

/21      /21

<em>x = 10</em>

When a number is a multiple of 6, what are the possible values for the ones digits?
Liula [17]
I would do this by first listing the multiples of 6 until I start to see a pattern with the one's digit.
6x0=0
6x1=6
6x2=12
6x3=18
6x4=24
6x5=30
6x6=36
6x7=42
6x8=48
...
The digits in bold are the one's digits so those are the only ones we really care about.  If you list just them it looks like: 0,6,2,8,4,0,6,2,8
Notice how the first set of 5 numbers seems as though it repeats in the 6th, 7th, and 8th numbers.  This probably means the pattern continues infinitely so the first 5 numbers are all the one's digits that can come from multiples of 6.  Thus your answer is: 0,6,2,8,or 4
