<u>Answer:</u>
The width of the base is 2.828 feet
<u>Explanation:</u>
Given the area of the table top is 4 square feet
The triangular table top is twice as high as it is wide at the base
Therefore, we can say that height = base
Area of a right angled triangle is calculated by, Area = ½ * base * height
In this case, height = base
Therefore, area =
Substituting the values,
4 =
= 8
Base = 2√2 = 2 * 1.414 = 2.828 feet
Therefore, the width of the base is 2.828 feet
Answer:
Probability that X <32 degrees
Convert this into percent by multiplying by 100
95.22% of days in February has minimum temperatures below freezing (32 degrees Upper F )
Step-by-step explanation:
Given that a city's mean minimum daily temperature in February is 22 degrees Upper F, with std deviation 6 degrees.
Let X be the minimum temperature in February
Then X is N(22,6)
To calculate percentage of days in February has minimum temperatures below freezing (32 degrees Upper F )
Probability that X <32 degrees
Convert this into percent by multiplying by 100
95.22% of days in February has minimum temperatures below freezing (32 degrees Upper F )
