Kara is sorting buttons by length for a craft project. The line plot shows the length of each button. If Kara lines up all the 3/4 inch buttons, what would be the total length?

The total length would be  

Step-by-step explanation:

The line plot figure is missing in the question, so below is the figure attached.

Now, to find the total length, if Kara lines up all the inch buttons.

So, from below figure we see that in the line plot inch buttons represents 3 buttons.

Length of buttons = inch.

Number of buttons = 3.

Now, to get the total length of inch buttons we multiply length of buttons by number of buttons:

Therefore, the total length would be

85.560%

step-by-step explanation:

conditional probability is defined as:

p(a|b) = p(a∩b) / p(b)

in other words, the probability that a occurs, given that b has occurred = the probability that both a and b occur / the probability that b occurs.

in this example:

p(turns 64 | turns 44) = p(turns 64 & turns 44) / p(turns 44).

if someone turns 64, they must have already turned 44, so:

p(turns 64 | turns 44) = p(turns 64) / p(turns 44)

on page 42, we see that of the original 100,000, 94944 turn 44, and 81234 turn 64.   therefore:

p(turns 64 | turns 44) = 81234 / 94944

p(turns 64 | turns 44) = 0.85560
