Answer:
x = -8/3
Step-by-step explanation:
So first let's simplify the expression. Grouping together like terms gives:
-3x + 7 = -1
Subtracting 7 from both sides gives
-3x = -8
Meaning x = -8/3
76 divided by 5 is 15.2 or (if you are needed a remainder) 15 r1
Answer:
Step-by-step explanation:
We are given that
Standard deviation, s=11.0995 kg
Sample size, n=10
We have to find the variance of their weights.
We know that
Variance=
Using the formula
The variance of their weights
=
=
Hence, the variance of their weights=
Answer:
range
Step-by-step explanation:
Mean- add all the numbers up and divide by how many numbers you added
65/8 =8.125
Range- Find the largest number and subtract the smallest number from it
20-3 =17
Median- put the numbers in order from least to greatest and find the number/s in the middle
3,3,4,5,6,8,16,20- since there are an even amount of numbers add the two in the middle and divide by 2
5+6=11 11/2 = 5.5
Mode- the number that repeats the most
3 repeats the most
Answer:
1/3 or 0.3 (recurring)
Step-by-step explanation:
Let's substitute our numbers into the equation.
27 = 9x + 24 I multipled 8 by 3 in order to get 24, because x equals 3.
Now take away 24 leaving 9x on its own.
3 = 9x
Divide 9 to separate it from x.
3/9 = x
Simplify the fraction.
1/3 = x
