Construct the cumulative frequency distribution that corresponds to the given frequency distribution speed number of cars. Speed Number of cars
0-29 4
30-59 16
60-89 60
90-119 20

The cumulative frequency distribution that corresponds to the given frequency distribution is shown in the explanation part as well as in the attachment.

Step-by-step explanation:

A cumulative frequency distribution is the sum of the class and all classes below it in a frequency distribution.

The cumulative frequency distribution that corresponds to the given frequency distribution speed number of cars is shown below and better shown in the attachment below.

SpeedNumber of carsCumulative frequency

0 - 29           4                                  4

30 - 59          16                                 20

60 - 89          60                                 80

90 - 119          20                                 100

d) by the cross product property, ab^2 = bc multiplied by ad

step-by-step explanation:

we are given

in the given triangle abc

angle a is 90° and segment ad is perpendicular to segment bc

we can see that

triangle(abc) and triangle(abd) are similar because they have common side and same angle (90 degree)

so, triangles(abc) and abd are similar

since, they are similar

so, the ratio of their sides must be equal

we get

now, we can cross multiply

and we get

so, this could be step to prove it

part d

step-by-step explanation:

theresa talked her parents into getting sd cards for her phone and her brother’s phone. inserting an sd card into a phone gives it more storage. they both get 8-gigabyte sd cards. how many bits of storage come with each sd card? type your answer in both scientific and standard notation.
