Each roast is 7.9 lbs so you multiply that by 3.
7.9x3=23.7
now add 1.4
23.7+1.4=25.1
the round of beef weighed 25.1 pounds
Answer:
B.
Step-by-step explanation:
x represents the amount of guests going to the birthday party, with the amount of money per guest being 12. You would multiply those two together, but as we do not know the total amount of guests, we keep it as a variable. 125 is the amount before the guests even know about the party, so therefore, you would need to use that equation.
Answer:
2
Step-by-step explanation:
Answer:
495
Step-by-step explanation:
12C4 = 12*11*10*9/(4*3*2*1) = 495
Answer: Hence, the probability that, out of the next 5 customers, 4 or more will use a coupon is:
1/3
Step-by-step explanation: Total 15 trials were recorded as follows:
43454 24511 55555 43453 55315 25215 32235 43311 11154 13342 42514 13223 44215 45313 13324
Now, we are asked to find the probability that, out of the next 5 customers, 4 or more will use a coupon.
We know that probability is the ratio of number of favorable outcomes to the total number of outcomes.
Hence, number of favorable outcomes are: 5
(32235 43311 13342 13223 13324 )
Total number of outcomes are: 15
( Since 15 trials were performed)
Hence, Probability is: 5/15 = 1/3
Hence, the answer is: 1/3
