Let:
Bk = Basketball score
N = Total scores
Ratio of basketball score to all scores:
Answer:
C. 0.403
Step-by-step explanation:
Binomial distribution has two parameter n and p. Here, n=15 and p=0.60.
We have to find the probability of 10 or more will show that the hamburger, French fries and a drink were ordered. P(X≥10)=?
The binomial probability distribution function for random variable X is
where q=1-p=1-0.6=0.4,n=15 and p=0.6.
P(X≥10)=P(X=10)+P(X=11)+P(X=12)+P(X=13)+P(X=14)+P(X=15)
=0.185938
=0.126776
=0.063388
=0.021942
=0.004702
=0.000470
P(X≥10)= 0.185938
+0.126776
+0.063388
+0.021942
+0.004702
+0.000470
P(X≥10)=0.403216
So, the probability of 10 or more will show that the hamburger, French fries and a drink were ordered is 0.403.
Hello!
To find out if this food is enough we will add together all of the prices and multiply it by three to see if it is enough.
3(4.89+5+8.49)=55.14
Yes! They will have enough money with $4.86 to spare!
I hope this helps!
Answer:
The most expensive item you can get is $23.44
Step-by-step explanation:
Because we are adding 8% in tax and 20% in tip, we know that overall we are spending 128% of the total dinner. So, we can divide the $30 we have to spend by 128% in order to find the original price of the item (don't forget to turn the percentage into a decimal first).
$30/1.28 = $23.44
Answer:
D
Step-by-step explanation:
x + y = 30
65x + 80y = $2,200
The only option that matches this is D
