Answer: The lower quartile is 6

Step-by-step explanation: To find the lower quartile of a set of data, we can find the median of the data and then find the median of the first half. This strategy is similar to dividing a cake into halves, and then dividing one of the halves in half so that you end up with a quarter of the cake.

Answer: 21.4

Step-by-step explanation:

Area of a triangle = (1.7 * 2)/2=1.7 m2

Area of a rectangle = 3 * 2 = 6 m2

3 * 6 = 18 m2 2 * 1.7 = 3.4 m2

the total area is 18 + 3.4 = 21.4 m2

Answer:

33 yards

Step-by-step explanation:

To find the number of ribbons that she used to decorate the dresses can be gotten by subtracting the amount of ribbon left from the total amount of ribbon she had.

She bought 100 yards. She has 67 yards left.

The table shows the temperature of an amount of water set on a stove to boil, recorded every half minute.

According to the given table the line of best fit is

f(x)=4.54x+77.84

The term "line of best fit" describes a line that passes across a scatter plot of data points and best captures their connection. Statisticians often utilise regression analysis software or manual computations to arrive at the geometric equation for the line using the least squares approach. A straightforward linear regression study of two or more independent variables will provide a straight line.

Hence, as asked by the question we need to find the time at which the tempurature will become 100°C.

To find that let us put f(x)=100 and find out the value of x for which it is satisfied.

4.54x+77.84=100

⇒ $x=\frac{100-77.84}{4.54}=4.88$
