Answer:
1/15
Step-by-step explanation:
4 × 1/6 × 1/10
reduce the numbers :
1/3 × 1/5
now multiplique the fractions
=1/15
370.75 ~ 371
Example:
To find the average for 10,18 and 13.
We just have add the following numbers and divided them by how many numbers you added.
Solution:
10 + 18 + 13 = 41
41 / 3 = 13.67 or 14
Then the average score is 14.
Measures of central tendency are a statistical method in which you measure and gather the middlemost value of the set of parameters.

Answer:
a = -4
Step-by-step explanation:
Solve for a:
-7 (3 a - 1) = 91
Divide both sides of -7 (3 a - 1) = 91 by -7:
(-7 (3 a - 1))/(-7) = 91/(-7)
(-7)/(-7) = 1:
3 a - 1 = 91/(-7)
The gcd of 91 and -7 is 7, so 91/(-7) = (7×13)/(7 (-1)) = 7/7×13/(-1) = 13/(-1):
3 a - 1 = 13/(-1)
Multiply numerator and denominator of 13/(-1) by -1:
3 a - 1 = -13
Add 1 to both sides:
3 a + (1 - 1) = 1 - 13
1 - 1 = 0:
3 a = 1 - 13
1 - 13 = -12:
3 a = -12
Divide both sides of 3 a = -12 by 3:
(3 a)/3 = (-12)/3
3/3 = 1:
a = (-12)/3
The gcd of -12 and 3 is 3, so (-12)/3 = (3 (-4))/(3×1) = 3/3×-4 = -4:
Answer: a = -4

3:0.5, 9:1.5, 6:1, 33: 5.5, 12:2, 39:6.5, 15:25.
the unit rate of eggs per 1 kg of flour = 6 eggs/1 kg of flour
Step-by-step explanation:
Usually tables go in ascending numerical order...the numbers only go up, reading from right to left. But the math for this has the numbers kind of jumping around.
3/0.5 = 9/x, then cross-multiply,
3x = 9(0.5)
3x = 4.5 then divide by 3
x = 1.5
--------------------------
3/0.5 = x/1
3 = 0.5x
6 = x
----------------------------
If you need me to keep showing the math for the rest of the table, let me know.
