Billy has $16.30 in dimes and quarters. If he has a total of 88 coins, how many of each type of coin does he have?

Answers

Answer:

38 dimes, 50 quarters

Step-by-step explanation:

Let d = dimes

Let q = quarters

d + q = 88

d = 88 - q

0.10d + 0.25q = 16.30

0.10d + 0.25q = 16.30

0.10(88 - q) + 0.25q = 16.30

8.8 - 0.10q + 0.25q = 16.30

8.8 + 0.15q = 16.30

0.15q = 7.5

q = 50

d = 88 - q

d = 88 - 50

d = 38

53, 13, 34, 41, 26, 61, 34, 13, 69 4) Mean : Median Mode : Range:​

Answers

Answer:

Mean: 34.8

median:34

Mode: 13,34

Range:65

Step-by-step explanation:

The value of Mean is 34.4

The value of Median is 34 (middle term)

The value of Mode is 13 and 34.

The value of Range is 56.

Here,

The data set is,

53, 13, 34, 41, 26, 61, 34, 13, 69

We have to find the value of Mean , Median , Mode and Range.

What is Range of the data set?

To find Range of the data set we have to find the difference of highest and lowest number of the set.

Now,

The data set is,

53, 13, 34, 41, 26, 61, 34, 13, 69

Firstly we arranged in the ascending order we get;

13, 13, 26, 34, 34, 41, 53, 61, 69

The Mean of data set is calculated as;

Mean = [tex]\frac{13+13+ 26+ 34+ 34+41+ 53+61+ 69}{9} = \frac{310}{9} = 34.4[/tex]

Hence, The value of Mean is 34.4

And, The Median is calculated as,

There are nine numbers (odd) in the data set, so the median is the middle value of given data set after arranging in ascending order.

Hence, The value of Median = 34 (middle term)

Now, The Mode is the number that appears most often within a data set.

In the data set,

13, 13, 26, 34, 34, 41, 53, 61, 69

Number 13 and 34 repeat two times.

So, The value of Mode = 13 and 34

Now, To find Range of the data set we have to find the difference of highest and lowest number of the set.

Here, In the data set;

The highest number = 69

The lowest number = 13

Hence, Range = 69 - 13 = 56

Therefore,

The value of Mean is 34.4

The value of Median is 34 (middle term)

The value of Mode is 13 and 34

The value of Range is 56
