The answer exactly is 93.5% because 58 over 62 is 0.935 then multiply it by 100 and there's your answer!
Answer:
Step-by-step explanation:
Total fruits T= 5+7 = 12
No. Of apple n(A) = 5
No. Of peaches n(P) = 7
P(A) 1st = n(A)/T = 5/12
P(P) 2nd = n(p)/(T-1) = 7/11
: P(A and P) = 5/12 × 7/11
= 35/132
Answer:
42 student tickets and 98 adult tickets
Step-by-step explanation:
Let's call the number of student tickets 's' and the number of adult tickets 'a'.
Then, we can write the two equations below:
5s + 8a = 994
a = 2s + 14
Using the value of 'a' from the second equation in the first one, we have:
5s + 8*(2s + 14) = 994
5s + 16s + 112 = 994
21s = 882
s = 42
Now, finding the value of 'a', we have:
a = 2*42 + 14 = 98
Solution
We solve the equation
We now solve the quadratic equation
The graph is given below
Answer:
2x^2 + 16x + 25
Step-by-step explanation:
The rule for expanding within brackets is:
(a + b)^2 = a^2 + 2ab + b^2
Thus,
2(x^2 + 8x + 16) - 7
After expanding from the brackets,
2x^2 + 16x + 32 - 7
or,
2x^2 + 16x + 25
