YOU WILL NOT FAIL, YOU SHALL PASS
Answer: w^6/9
Step-by-step explanation:
first, i evaluated the powers.
3^-2 x 1 x 1/w^-6
then, i calculated those products.
3^-2/w^-6
then, i just expressed it with a positive exponent.
w^6/3^2
finally, i evaluated that.
w^6/9
Step-by-step explanation:
First, find the zeroes of the parabola
So the zeroes or where the curve crosses the x axis is at 4 and -3.
Now, we take the derivative of the function.
Plug in -3, and 4 into the derivative function
So at x=-3, our slope of the tangent line is -7 and must pass through (-3,0). So we use point slope formula.
At x=4, our slope of tangent line is 7, and pass through (4,0) so
So the equations of tangent is
The x-int is (16,0)
you plug in 0 for y and solve
x-6(0)=16
x=16
the y-int is (0, -8/3)
you plug in 0 for x and solve
0-6y=16
y= -16/6
simplify by dividing both the numerator and the denominator by 2
y= -8/3
About 25 percent of the data are greater than 20.(option a)
About 50 percent of the data are less than 15. (option b)
20 is wrongly interpreted as the median. 20 is the third quartile. The data between 11 and 20 is 50%.
<h3>How can a box-and-whisker plot be interpreted?</h3>
A box plot is used to study the distribution and level of a set of scores. The scores are distributed into 4 groups. Each group has a value of 25%
The box plot consists of two whiskers and a box. The first whisker represent the minimum value. The second whisker represents the maximum number.
On the box, the first line to the left represents the lower (first) quartile. 25% of the score represents the lower quartile. The next line on the box represents the median. 50% of the score represents the median. The third line on the box represents the upper (third) quartile. 75% of the scores represents the upper quartile.
20 is the third quartile. Score greater than 20 is 25% (100% - 75%)
15 is the median. Scores less than 15 is 50% (100 - 50%),
