Answer:
$636.53
Step-by-step explanation:
Tax: 9.75/100 × 579.98
= 56.54805
Total cost = 579.98 + tax
= 636.52805
The answer is 1/4
Explanation
===============================
The question focuses on "if the student is known to be a boy..." we would obviously know that we would focous on only the total of the boys.
We have the formula for the probability of an event of happening which we would call event A (a boy being left-handed). P(A)= number of favorable outcomes/ total number of possible outcomes. The left-handers would go in the favorable outcomes since we want the probability of a boy being left handed and we would place the total boys in the total number of possible outcomes since all of them are going to be the one to be randomly picked. 50 left-handed/ 200 total boys. We have our fraction that is 50/200 as the probability but we can simplify it! We simplify 50/200 to get 1/4!!! 1/4 is the probability of a boy being picked that is left-handed!
Hope this helps!
Answer: Tom's solution is incorrect.
Step-by-step explanation:
When you add 3/6 + 1/2 it equals ?.
3 + 1 = ?
6 + 2 = ?
We must have common denominators to do this problem.
So we must have 6 as our common denominator.
So 2 x 3 = 6. But we have to do the same to the Numerator.
So 1 x 3 = 3.
Now our problem is 3/6 + 3/6 = ?
3 + 3 = 6/6. Or 1
1 does not equal 4/12 or 1/3. So it makes it Incorrect.
What you should say:
Tom is incorrect, it is because 3/6 + 1/2 = 1, 1 does not equal 4/12 or 1/3. So, it makes it reasonable for the correct answer to be Incorrect
Answer:
The length of EB is found 15
Step-by-step explanation:
As the diagram of the circle is not given in the question, I've found the diagram of the same question from internet and attached below. So that we can have a better understanding)
We can see in the diagram the chord AB and chord CD intersect each other at point E.
Each of the chord is divided into two segments.
According to the Intersecting Chords Theorem:
Products of the lengths of line segments on each chord are equal
Which means that
(AE)(EB) = (CE)(ED)
Substitute the given values;
(4)(EB) = (10)(6)
4(EB) = 60
EB = 15
Y goes up by +3 and x goes +1
