Answer:
Wouldn't be 100% since all the numbers on a standard number cube are less than 7?
Step-by-step explanation:
The following list gives the number of public libraries in each of 11 cities. 7, 11, 8, 7, 8, 7, 8, 11, 8, 10, 7 Find the modes
AlladinOne [14]
Answer:
The mode are: 7, 8
Step-by-step explanation:
Given
Required
Determine the mode
We start by arranging the given data in ascending order
The ordered data are:
From the above data.
7 has a frequency of 4
8 has a frequency of 4
10 has a frequency of 1
11 has a frequency of 2
The data with the highest frequency is the mode.
We can see that 7 and 8 both have frequencies of 4
<em>Hence, the mode are: 7, 8</em>
Answer:
The area of the circle is 153.94m²
Step-by-step explanation:
radius = half of diameter
d = diameter
r = 14m / 2 = 7m
To solve this problem we need to use the area formula of a circle:
a = area
r = radius = 7m
π = pi
a = π * r²
we replace with the known values
a = π * (7m)²
a = π * 49m²
a = 153.93804 m²
Round to the nearest hundredth
a = 153.93804m² = 153.94m²
The area of the circle is 153.94m²
Answer: All of them can be a triangle except for #11 because the two shortest sides don't add up to more than the longest side.
#10 is a Pythagorean Triple so it is a right triangle.
To determine if the triangle is an acute or obtuse triangle, we just need to plug the values into the Pythagorean Theorem. If the sum of the legs squared is greater than the hypotenuse, it's an acute triangle. If the sum of the legs square is less than the hypotenuse, it's an obtuse triangle.
Using this logic, 7 & 12 will be obtuse while 8 & 9 will be acute.
Answer:
14 or 15
Step-by-step explanation:
14 squared is 196
15 squared is 225
I memorized these, my math tutor recommends to memorize the squares up to 20. :)
