Chapter 10.2, Problem 17HP

a.

To determine

To calculate most frequent temperature of H’s town.

Answer to Problem 17HP

The most frequent temperature is 56?

Explanation of Solution

Given information:

Temperature graph of H’s town

Formula used: Graph reading

Reading the graph,

Highest number of dots are present at 56°F.

Therefore, the most frequent temperature at H’s town is 56°F.

b.

To determine

To calculate total number of days temperature recorded.

Answer to Problem 17HP

The total number of days temperature is recorded is 20 days.

Explanation of Solution

Given information: Temperature graph

Formula used: Graph reading

Reading the graph,

In the graph one dot represents one day.

  $1dot=1day$

On calculating the number of dots at each temperature,

Number of dots at 50°F= 3

Number of dots at 51 °F = 1

Number of dots at 52 °F = 5

Number of dots at 53 °F = 2

Number of dots at 54 °F = 0

Number of dots at 55 °F = 2

Number of dots at 56 °F = 7

For total number of days, sum all the dots,

  $Days=3+1+5+2+0+2+7$

On solving,

  $Days=20$

Hence, total number of day= 20

c.

To determine

To calculate number of days when temperature was 53? or above

Answer to Problem 17HP

11 days the temperature was 53°F or above

Explanation of Solution

Given information:

Temperature graph of the town

Calculation: Reading the graph,

In the graph one dot represents one day.

  $1dot=1day$

On calculating the number of dots at each temperature,

Number of dots at 53 °F = 2

Number of dots at 54 °F = 0

Number of dots at 55 °F = 2

Number of dots at 56 °F = 7

For total number of days, sum all the dots,

  $Days=2+0+2+7$

On solving,

  $Days=11$

Hence, total number of day= 11
