A 12 ft tall street light is making an 18 ft shadow. At the same time, a nearby building is making a 72ft shadow. How tall is the building? I’m really bad at math

height of building is 48 ft.

Step-by-step explanation:

This is a problem of ratio.

IN the given problem

ratio of object and its shadow will remain same for any object .

Given

A 12 ft tall street light is making an 18 ft shadow

ratio of

height of street light : height of shadow = 12:18 = 2:3

This ratio will be same for building as well

let the height of building be x ft

height of building : height of building shadow = x:72

x:72 will be equal to 2:3

x:72 = 2:3

x = 2/3*72 = 48

Thus, height of building is 48 ft.

step-by-step explanation:

just count the values of x & y of the vertex of the graph and see how many units in the x and y direction will get you from the f(x) graph to the f(x) graph

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.
