Answer:

The Median is 5

Step-by-step explanation:

The median is the middle number in a set of data, when the data has been written in size order.

0 1 2 4 5 5 5 6 6 6

As there is an even number of data the median is the average of the middle two values. As the middle 2 values are both 5, then the average of these is also 5. Therefore, the median is 5.

To find the mean of the set of data, add all the values together then divide by the number of data values:

(0 + 1 + 2 + 4 + 5 + 5 + 5 + 6 + 6 + 6) ÷ 10 = 4

Therefore, the mean is 4.

The Median is a better measure of central tendency as extreme values (outliers) do not affect it. From inspection of the dot plot, the majority of the data values are 5 and 6. Therefore, the lower values *could* be outliers, so 5 is a more realistic measure of central tendency.

You push your younger sister on a swing one time and then allow your sister to

Ber [7]

Answer:

My sister will swing the total distance = 40 feet

Step-by-step explanation:

On the first swing my sister travels a distance of 8 feet.

In every successive swing she travels 80% of the distance of the previous distance.

So the sequence formed by the distance traveled in every swing will be a geometric sequence.

First term of the sequence 'a' = 8 feet

common ratio 'r' = 0.80

Since this sequence is an infinite geometric sequence,

Sum of this sequence = $\frac{a}{(1-r)}$ [Since r < 1]

= $\frac{8}{1-0.8}$

= $\frac{8}{0.2}$

= 40 feet

Therefore, my sister will cover the total distance = 40 feet

A credit card company charges 18.6% percent per year interest. Compute the effective annual rate if they compound, (a) annualy,

Darina [25.2K]

Answer:

a) Effective annual rate: 18.6%

b) Effective annual rate: 20.27%

c) Effective annual rate: 20.43%

d) Effective annual rate: 20.44%

Step-by-step explanation:

The effective annual interest rate, if it is not compounded continuously, is given by the formula

$I=C(1+\frac{r}{n})^{nt}-C$

where

C = Amount of the credit granted

r = nominal interest per year

n = compounding frequency

t = the length of time the interest is applied. In this case, 1 year.

In the special case the interest rate is compounded continuously, the interest is given by

$I=Ce^{rt}-C$

(a) Annually

$I=C(1+\frac{0.186}{1})-C=C(1.186)-C=C(1.186-1)=C(0.186)$

The effective annual rate is 18.6%

(b) Monthly

There are 12 months in a year

$I=C(1+\frac{0.186}{12})^{12}-C=C(1.2027)-C=C(0.2027)$

The effective annual rate is 20.27%

(c) Daily

There are 365 days in a year

$I=C(1+\frac{0.186}{365})^{365}-C=C(1.2043)-C=C(0.2043)$

The effective annual rate is 20.43%

(d) Continuously

$I=Ce^{0.186}-C=C(1.2044)-C=C(0.2044)$

The effective annual rate is 20.44%

One hiking club charges $16 to become a member and $3 to participate on each hike. Another club charges no membership fee, but c

yawa3891 [41]

Answer:

x < 8

Step-by-step explanation:

x= # of hikes

3x +16 =5x

-3x. -3x

16=2x

16/2= 8

2x/2= x

8=x

x=8

check:

3(8) +16 =5(8)

24 +16 =40

40=40 ✓

there for at 8 hikes with either deal it would be the same but if you went up a number of hikes for the first option it would only be $43.00 spent in total. but with the second option it would be $45.00.

as a contractor to make a hole 4 5/8 inches diameter. express the mixed number as an improper fraction.

san4es73 [151]

The mixed number as an improper fraction is 37/8

<h3>How to express the mixed number as an improper fraction?</h3>

The diameter is give as:

Diameter = 4 5/8

Next we convert the above number to an improper fraction

The numerator is calculated as

Numerator = 8 * 4 + 5

This gives

Numerator = 37

Hence, the mixed number as an improper fraction is 37/8
