Answer:
2/3= 14/21....red beads...4/21 blue beads...14+4= 18/21...so you need 3/21 more to finish the necklace and 3/21=1/7 in white beads
Step-by-step explanation:
It can be easily assumed that most information's are already given in the question. Based on those information's, the answer can be deduced.
rt = [(3/4)r] * (t + 12)
4rt = 3r (t + 12)
4rt = 3rt + 36r
4rt - 3rt = 36r
rt = 36r
t = 36
From the above deduction we can conclude that the time taken by Carmen to ride to the market is 36 minutes
Then
Time taken by Carmen to ride home = 36 + 12 = 48 minutes
The <em>correct answer</em> is:
A single outlier causes the value of the median to move slightly toward the outlier.
Explanation:
Overall, outliers have very little effect on the median. However, they do affect it some.
If the outlier is a very large number, the median will slightly increase as compared to the data set without the outlier.
If the outlier is very small, the median will slightly decrease compared to the data set without the outlier.
In both instances, the median is moved slightly towards the outlier.
First we find the mean (average)
(17 + 18 + 19 + 20 + 21) / 5 = 95/5 = 19
now subtract 19 from all values...then square it
17 - 19 = -2...-2^2 = 4
18 - 19 = -1...-1^2 = 1
19 - 19 = 0...0^2 = 0
20 - 19 = 1....1^2 = 1
21 - 19 = 2...2^2 = 4
now take the mean (average) of those
(4 + 1 + 0 + 1 + 4) / 5 = 10/5 = 2 <== this is ur variance
standard deviation is the square root of the variance...
sq rt 2 = 1.414
Remember order of operations
PEMDAS which stands for
Parenthasees (or grouping symbols)
Exponents (square roots are also exponents, remmeber that)
Multiplication or Division, whichever comes first (remember, division is multiplication by a fraction
Addition or Subtraction, whichever comes first (subtraction is additon of a negative)
so
8-6*4+10/2=
no parenthases or exponents so multiply
-6*4=-24
we get
8-24+10/2
now divide
10/2=5
now we get
8-24+5
doesn't matter wha torder we do
-16+5
-11
