Answer:

Arnold

Step-by-step explanation:

In order to compare, you'd have to find out how much they paid for each pound of tri-tip. So, to do this, you would divide the total amount of money the spent on the pounds by the number of pounds they bought. So for Kevin, you'd divide 29.97 by 3 to get that Kevin paid $9.99 for each pound. For Arnold, you'd divide 35.96 by 4 to get that Arnold paid $8.99 for each pound. And 8.99 is less than 9.99, so Arnold was right.

Total freshman = 58. Number of freshman who prefer cheese toppings= 14. Determined the probability that a freshman prefer cheese
Yakvenalex [24]

Answer:

The probability that a freshman prefer cheese toppings  is   0.241

Step-by-step explanation:

Probability of any event E =  \frac{\textrm{Number of favorable outcomes}}{\textrm{Total number of outcomes}}

Here, let E   :  Event of choosing cheese toppings

So, the number of favorable outcomes = 14

Total number of outcomes = 58

So, P(E) =  \frac{\textrm{Number of students who like cheese toppings}}{\textrm{Total number of students}}

or, P(E) = \frac{14}{58} = 0.241379

So,the probability that a freshman prefer cheese toppings  is   0.241379

Rounding of 0.241379  to the <u>nearest thousandth</u>, we get

Here , in 0.241379 thousandth digit is 3, and 3 < 5,

so the value of P(E) = 0.241

How would I solve this problem if n=5 with no decimals?
Ostrovityanka [42]
This equals to 2/(1/5)+(1/5)/2.
                     =2 x 5+1/5 x 1/2
                     =10+1/10
                     =10 1/10 <---- This is mixed fraction, since you didn't want decimals.
