What are the quartiles of the data

Mathematics
1 answer:
MAXImum [283]2 years ago
3 0

The quartiles of the data are: 60.5,64,66

Option(b) is correct.

The quartile divides the distribution into four groups and calculates the range of values above and below the mean.

A quartile separates the dataset into four categories by dividing the data into three points: the lowest, median, and upper quartiles.

Similar to how the median divides the data in half, with 50% of the measurements falling below it and 50% falling above it, the quartile divides the data into fourths, with 25% of the measurements falling below the lower quartile, 50% falling below the median, and 75% falling below the upper quartile.

The interquartile range, a measurement of variation around the median, is calculated using quartiles.

For the given data set: 58,60,60,61,62,64,64,64,66,70,72

Median = 64

Lower quartile = Median of the lower half = 60.5

Upper quartile = Median of the upper half = 66

damaskus [11]

Answer:

P = $2448.89

P ~= $2,449

He need to deposit $2,449

Step-by-step explanation:

Given:

Interest rate r= 7% = 0.07

Number of years n = 3 years

Future value that should be meet A = $3000

We need to calculate the initial investment (Principal P). Using the compound interest formula:

A = P(1+r)^n

P = A/(1+r)^n

Substituting the values of A, r, n, we have;

P = 3000/(1+0.07)^3

P = $2448.89

P ~= $2,449

Need help asap. Simplify the expression 6/c+4/c^2 show work
Zina [86]

By taking a common denominator, we can find out that the simplified expression of the given expression is \frac{6c+4}{c^{2} } .

The given expression is -

\frac{6}{c}+\frac{4}{c^{2} } ---- (1)

We have to simplify the expression.

From equation (1), we have the given expression as -

\frac{6}{c}+\frac{4}{c^{2} }

Establishing common denominator c^{2}, we have

\frac{6c}{c^{2} }+\frac{4}{c^{2}}

Combining the numerator and common denominator, we have

\frac{6c+4}{c^{2} }

Thus, the simplified expression of the given expression is \frac{6c+4}{c^{2} } which is obtained by taking a common denominator.

The average cost for a gallon of gasoline increased from $2.56 one year to $3.18 the next year. What is the percent of increase,
frez [133]
%change=100(final-initial)/initial

In this case:

%change=100(3.18-2.56)/2.56

%change=100(0.62)/2.56

%change=62/2.56

%change=775/32%

%change=24.21875%

%change≈24%  (to nearest whole percent)
