I think that the answer would be 5/5
C) because the 7 and x right next to each other represents multiplication. so it's:
7x=91
7X(Allison's money)=91
Perimeter = 2L + 2W → 240 = 2L + 2W → 120 = L + W → 120-L = W
Area = L x W → Area = L(120-L) → Area = 120L - L²
Find the derivative: dA/dL = 120 -2L → 0 = 120 - 2L → L = 60
Area = 120L - L² = 120(60) - (60)² = 7200 - 3600 = 3600
The maximum area is 3600 yds²
THE ANSWER IS B, CAUSE THE HIGHEST EXPONENT FOR A QUADRATIC FUNCTION SHOULD BE 2, AND WHICH A,B AND C SHOULD NOT BE EQUAL TO ZERO. HOPE THIS HELPS!
Step-by-step explanation:
1.
when 3 coins are flipped the following outcomes are possible
h = heads, t = tails
h h h
h h t
h t h
h t t
t h h
t h t
t t h
t t t
yes, there have to be 8 options, because we have 3 positions with 2 possible outcomes. that means
2×2×2 = 2³ = 8 possibilities.
2.
at least 2 tails means 2 or 3 t in the list item :
h t t
t h t
t t h
t t t
3.
so, 4 out of the 8 possible outcomes. the probability is then therefore
4/8 = 1/2 = 0.5
