A) For the following function, use the given set of intervals to estimate the slope of the tangent line of the function at x=−2 x 2 by producing the slopes of the secant lines that pass through the x x-values of each of the intervals. f(x)=2x2+1;[−4,−2],[−3,−2],[−2.5,−2 ],[−2.25−2] b) For the following function, use the given set of intervals to estimate the slope of the tangent line of the function at x=6x6by producing the slopes of the secant lines that pass through the xx-values of each of the intervals.
f(x)=3x2;[6,8],[6,7],[6,6.5],[6,6.2 5]

true

explanation:

you never say the total so we cant find the percentage used for petrol

step-by-step explanation:

see below

step-by-step explanation:

7.   there are 10 data points in the set.   the middle point is between 5 and 6.   the middle point in the top half is 8   and the middle point in the bottom half is 3. to find the iqr , take point 8 and subtract point 3

mid term   point 8 = 100   point 3 = 88

iqr = 100-88 = 12

final   point 8 = 93   point 3 = 78

iqr = 93 - 78 = 15

the final has the greatest iqr

6.   b - there is a high data value that causes the data set to be asymmetrical for the males: the data for males are high and asymmetrical .   there is an outlier for the males that skews the data

5.   the   iqr is a better measure of spread for the movies and basketball games.   since the basketball game has an outlier, we do not want to use standard deviation for measurement.  

3.   the exam median is much higher than the class median.   the median line is farther to the right on the exams

2.   there is no way to tell what the means are from the box and whisker plots.  

the highest percentage for deaths in construction from highest to lowest is as follows: falls, struck by objects, electrocution, and caught-in/between. these four are collectively known as fatal four.

in the case of falls, the type that is responsible for the overall highest death in the category is falls from roofs.
