Answer:
-5/2+-1/2√37≤x≤-5/2+1/2√37
Step-by-step explanation:
Step 1: Find the critical points
-x^2-5x+3=0
For this equation: a=-1, b=-5, c=3
−1x^2+−5x+3=0
x=−b±√b2−4ac/2a
x=−(−5)±√(−5)2−4(−1)(3)/2(-1)
x=5±√37
/−2
x=-5/2+1/2√37
Step 2: Check intervals in between critical points
x≤-5/2+1/2 √37 (Doesn't work in original inequality)
-5/2+-1/2√37≤x≤-5/2+1/2√37 (Works in original inequality)
x≥-5/2+1/2 √37 (Doesn't work in original inequality)
Your total is 96.88 and you take 20% from that so your down payment is $4.84. Hope this helps!
Answer:
P(prime,prime) = 4/10 x 4/10 or 2/5 x 2/5 = 4/25
Step-by-step explanation:
2,3,5,7 are primes from 1 through 10
probability of drawing a prime card is 4/10
first you put 18/y=2
you multiply by 18 to get y=36
your answer is 36, y=36
3 divided by 10 would equal 0.3, the answer is C
