Answer:
12 bracelets
Step-by-step explanation:
Steps of adding -6 + 4 using number line are as following:
1) Draw a number line by ranging from -10 to +10.
2) Point out -6 on the number line.
3) Because 4 is added to -6 on the number line, please move 4 number right to -6 on the number line. We always go right in addition and go left in subtraction on the number line.
4) The number we reach 4 on right side would be our final sum.
5) From the number we can clearly see that moving 4 number on right to -6, we get -2.
So, final answer is -2.
Y-y1=m(x-x1)
Y+5=7/3(x+3)
Y+5=7/3x+7 That one it's point-slope form
Y+5=7/3x+7
-5 -5
Y=7/3x+2 That one it's slope-intercept form.
Answer:
The correct option is b.
Step-by-step explanation:
The formula for standard deviation is

where,
is mean of the data and n is number of observation.
The variance of a stock's returns can be calculated by the above formula.
Variance of stock's returns is the average value of squared deviations from the mean.
Therefore the correct option is b.
