Answer:
Pr(≥ 70%) = 2/5 = 0.4
Step-by-step explanation:
This question is incomplete as we can't get an exact answer without the dot plot diagram.
We can tell from the question, we are to determine the probability of having ≥ 70% students that play sports
The dot plot diagram used in solving the question has been attached.
Total number of samples = 20
From the dot plot, 50% of students play sport. That is, 50% have more people playing sport than others.
The chance of getting a sample proportion of 70% or greater= probability of students that like sports ≥ 70%
= (sum of people that like sports ≥ 70%)/(total number of sample)
Pr(≥ 70%) = (4+3+1)/20
Where Pr = probability
Pr(≥ 70%) = 8/20
Pr(≥ 70%) = 2/5 = 0.4
Answer:
20
Step-by-step explanation:
First, let's find how much she spent on the expensive calculators
40 times $16400= $656,000
Now, lets find how much money she had for the cheap calculators.
$774,000- $656,000=$118000
Now that we have her budget (money remaining) for the cheaper calculators, lets divide that by the price for each individual calculator.
$118000/$5900=20

Answer:
8 boxes.
Step-by-step explanation:
We have to find out how many times 6 goes into 45.
45/6 = 7.5
Unfortunately, you can't have half a box. To correct this and be able to find the fewest amount of boxes, you simply round to the nearest whole number.
In this case, since the max amount of shirts that can fit in a box is 6, you must round up.
7.5 rounded up is 8.
<em>The fewest amount of boxes you need is 8.</em>
The answer is 12 because the lines of the parrellel shape he’ll come across each other
Answer: $2.50
Step-by-step explanation: First, divide 10 by 4, which is 2.5.
Second, convert the decimal into a monetary amount, by adding a 0 at the end of the decimal, then adding a dollar sign. I hope this was helpful! FYI, I did NOT Google the explanation, it was all me!!!
