Answer:
3
Step-by-step explanation:
Greatest common factor (GCF) of 6 and 15 is 3. We will now calculate the prime factors of 6 and 15, than find the greatest common factor (greatest common divisor (gcd)) of the numbers by matching the biggest common factor of 6 and 15.
Hope this helps

<h3><em>
Answer:</em></h3>
<em>mean = 4</em>
<em>Median = 3</em>
<em>Mode = 1</em>
Step-by-step explanation:
first let’s arrange the numbers from least to highest:
1 , 1 , 1 , 2 , 3 , 3 , 5 , 5 , 15
=====================
The median is the number that’s comes in the middle of the data set ⇒ median = 3 ( the fifth number in the data set)
1 , 1 , 1 , 2 , <u>3</u>, 3 , 5 , 5 , 15
________________________
The mode is the number that repeats the most ⇒ mode = 1 (repeated 3 times)

Answer:
49/4
Step-by-step explanation:
x^2 + 7x = 4
Take the coefficient of x
7
Divide by 2
7/2
Square it
(7/2) ^2 = 49/4
Add this to each side
x^2 + 7x +49/4= 4+49/4
The triangle in the drawing is semi equilateral. Therefore a=√(14^2-7^2)=12.12 cm
The base of a regular pyramid consists of 6 equilateral triangles. The area of each triangle is: (14*12.12)/2 = 84.87 cm^2
The base: 6*84.87=509.22 cm^2
