Answer:
<u>145 people were surveyed</u>
Step-by-step explanation:
1. Let's review the information given to answer the question correctly:
Percentage that indicated they preferred walking to running = 90%
2. If 130 people preferred running to walking, how many people where surveyed?
For answering this question, we will use the Rule of Three simple, this way:
x = Number of people surveyed
90 * x = 130 * 100
90x = 13,000
x = 13,000/90
x = 144.44
But we need a whole number for an accurate answer, so we round the value of x to the next whole number.
<u>145 people were surveyed</u>
Answer:
The range is 31
Step-by-step explanation:
Range is highest number - lowest number.
The highest number is 54 and the lowest is 23.
54-23=31
Answer:
Not sure if this is correct but this is what I found.
area of sector=74.84
radius = 8
angle of sector=?
74.84=1/2×8²×angle of sector
74.84=32 × angle of sector
74.84/32= angle of sector
2.33875=angle of sector
Step-by-step explanation:
Sorry if it is incorrect.
