Answer:
$6.83
Step-by-step explanation:
A brownie costs $3.45, an ice cream costs $2.43, and a cookie costs $0.95. So $3.45 + $2.43 + $0.95 = $6.83. If you need to know the change if they paid with $10.00 also . . . That would be $10.00 - $6.83 = $3.17 change.

Complete question :
A test consists of 10 multiple choice questions. Each question has 5 choices. To pass the test, a student must answer at least 6 questions correctly. If a student guesses on each question, the probability of getting it right is 20%. What is the probability that the student will pass the test?
Answer:
0.006370
Step-by-step explanation:
Number of options = 5, with only one correct,hence, p = 1/5 = 0.2
Number of questions = 10
Number of correct answers required to pass = 6
Using binomial distribution formula :
P(x =x) = nCx * p^x * (1 - p)^(n - x)
p = 0.2 ; 1 - 0.2 = 0.8
n = 10 ; x = 6
P(x ≥ 6) = p(6) + p(7) + p(8) + p(9) + p(10)
The formula above can be used to obtain the individual probabilities then taking the sum or we can obtain the solution using a calculator ;
Using a binomial probability distribution calculator with the parameters given :
P(x ≥ 6) = 0.0063693824
= 0.006370 ( 4 decimal places)
You need a table with the content of sodium per serving.
This is the table:
butter 1 pat 41mg
coffe 250 ml 0
eggs 1 serving 60mg
toast 1 slice 170mg
orange
juice 250 ml 4 mg
With that table you can calculate the content of sodium in the breakfast, this way:
<span>orange juice: 1 * 41 mg = 4 mg
2 eggs: 2*60mg = 120 mg
2 slices of toast with butter on each: 2 * ( 170mg+41mg) = 422mg
and coffee: 1 *0 = 0
The total sodium ingested is: 4 mg + 120 mg + 422 mg = 546 mg
Answer: 546 mg
</span>
the answer is 1/10 :))))))))
