Answer 1

Answer:

• The architect spends an average of 17 hours per week on his work.

Explanation:

Given that:

• An architect has 6 weeks to prepare a design and outlay the plan of mall.
• He spends 19, 22, 21, 14, 16 and 10 hours over the period of 6 weeks.

To Find:

• Average number of hours per week the architect spends on his word.

Process:

Here, we have been given that a architect has 6 weeks to prepare a design of a mall. It is given that the architect spends 19 hours, 22 hours, 21 hours, 14 hours, 16 hours and 10 hours on the design over the period of 6 weeks. We need to find out the average number of hours per weeks spend by the architect. We may use the formula: Average = Sum of observations/Number of observations to find out the average hours spend by the architect.

Solution:

As we know that,

$\sf{Average=\dfrac{Sum\;of\;observations}{Number\;of\;observations }}$

Substituting the values,

$\sf{\longmapsto\dfrac{19+22+21+14+16+10}{6}}$

Adding the numbers,

$\sf{\longmapsto\dfrac{102}{6}}$

Dividing the numbers,

$\sf{\longmapsto17}$

Hence,

• The architect spends an average of 17 hours per week on his work.
