38.65*.20=7.73
38.65+7.73=46.38
So the total bill is $46.38.
100-46.38=53.62
So she’ll receive $53.62 in change.
Answer:
<em>The probability that exactly 2 of the rolls is a sum of 7 will is </em><em>0.296</em>
Step-by-step explanation:
The probability of rolling a sum of 7 when rolling two dice simultaneously is 0.167.
Let us assume that, A be the event that the sum is 7. So,
Binomial probability represents the probability that a binomial experiment results (i.e either success or failure or only two results) in exactly x successes.
So the probability that exactly 2 of the rolls is a sum of 7 will be,

Answer:
-5
Step-by-step explanation:
The equation given is in slope intercept form.
A slope-intercept equation that passes through the origin would not have the '+ b' part because there is no intercept.
When there is no intercept we would not write the '+ 0'.
The slope given is -5.
Hope this helps.
