Answer:3.4d
Step-by-step explanation: From Range Rule of thump:
Standard Deviation = (Range)/4
=[(Highest value - lower value)]/4
=(189.2 - 175.6)/4
=13.6/4
=3.4
Answer:
he could buy 5 cookies and 7 brownies
Step-by-step explanation:
8.75 for the brownies and it is 3.75 for the cookies = 12.50
7*1.25=8.75 5*0.75= 3.75 equals 12.50 all together
he can't buy more than 12 cookies and brownies all together.
There could be two unit rates for this problem. We find the unit rate by dividing how much something gets for however much it is. For example:
If we wanted to find out how many pounds of dog food each dog gets, we divide the pounds of dog food all of them get by how many dogs there are:
128/16 = 8
So each dog receives 8 pounds of dog food. This is one unit rate.
Another unit rate would be how many dogs does one pound of dog food feed. We calculate this by dividing the amount of dogs by the pounds of dog food they received:
16/128 = 1/8
So one pound of dog food feeds 1/8 of a dog, this is the other unit rate.
To find the experimental probability, you will add the outcomes that resulted in even number and make that a ratio to the total number of outcomes.
<u>(12 + 14 + 18)</u>
(13 + 12 + 12 +14 + 11 + 18)
44/80 = 0.55
0.55 = 55%
The answer is choice D.
