Answer:
£29.37
Step-by-step explanation:
→ First step is to find the amount of hours it takes for 5 builders
→ Now we know how long 5 builder takes we need to multiply the hourly rate by their time worked
Answer:
The rate of change determines the average speed of the ball when it is dropped from the building.
Step-by-step explanation:
d(t) = 16t^2
when t = 2
d(t) = 16 (2)²
d(t) = 64
when t = 5
d(t) = 16 (5)²
d(t) = 400
Average speed/rate of change = distance/time = 64/2 = 32 feet
Average speed/rate of change = distance/time = 400/5 = 80 feet
The rate of change determines the average speed of the ball when it is dropped from the building.

Step-by-step explanation:
(a) A histogram is like a bar graph, but with ranges instead of values.
(b) The distribution is approximately uniform, with slightly more people at the younger and older ends than in the middle.
(c) The ages do not appear to come from a normal distribution. Normal distributions are bell-shaped, tall in the middle and short on the sides.
Given the bar graph above, the difference <span>in monthly electric cost appear to be great because of the choice of scale.
In scaling, the narrower the intervals of the axis, the larger the graph and the more highlighted the relative difference between the components of the graph.
Conversely, the wider the </span><span>the intervals of the axis, the smaller the graph and the less
highlighted the relative difference between the components of the graph.
Therefore, to make </span><span>the difference in monthly electric cost appear not to be as great</span>, we widden the intervals on the y-axis.
i.e. '<span>The interval on the y-axis could be changed to count by 20s.'</span>
