Let
x---------> <span>The probability that a student takes Spanish
y-------> </span><span>the probability that a student takes Drivers Education given that the Student is taking Spanish
z-------> </span><span>The probability that a student at school takes Drivers Education and Spanish
we know that
z=x*y------> solve for y
y=z/x
z=87/1000
x=68/100
substitute
y=(87/1000)/(68/100)-----------> y=87/680
the answer is
87/680</span>
Answer:
<h2>
<em><u>THE CORRECT ANSWER IS B- 73 FEET</u></em></h2>
<em>The given condition in question will form a right angle triangle </em>
<em>and the length of sides of triangle are given 55ft, 48ft and missing one.</em>
<em>Now using pythagoras theorem</em><em>,55²+48²= x²</em>
<em>x² = 3025 + 2304</em>
<em>x² = 5329</em>
<em>Taking square root of 5329 will give 73 ft!</em>
Answer:
100% means like everything, the total
Step-by-step explanation:
percent is like "out of a hundred"
so 100/100
is everything
The total
Answer:
Adult: 50 tickets
Child: 34 tickets
Step-by-step explanation:
Let a be the amount of adult tickets
Let c be the amount of child tickets
Equation:
a + c = 84
14a + 9c = 1,006
Step 1: Multiply a + c = 84 with -9, to canceled c.
-9 (a + c = 84) → -9a - 9c = -756
14a + 9c = 1006 → 14a + 9c = 1006
Step 2: Combined the 2 equation together, and solved it.
-9a - 9c = -756
<u>14a + 9c = 1006</u>
<u> 5a</u> = <u>250</u>
5 5
a = 50
Step 3: Plug 50 into the one of the equation, and solved it.
a + c = 84 → 50 + c = 84
<u>-50 -50</u>
c = 34
Answer: Adult tickets (a) = 50 and Child tickets (c) = 34
To check the answer plug the two number into the equation ( Make sure to add 50 for a and 34 for c).
