The answer would be 70 and mental math is to break it down to smaller easier pieces

Add 3 to 37 to get 40 and then subtract 3 from 33 to get 30. add 40 and 30 so you get 70 and you don't have to worry about adding or subtracting the other 3's you added & took away since they canceled each other out!

Answer:

Step-by-step explanation:

The equation of the parabola can be represented as

$y = a(x + 1)(x - 5)$

for some constant a.

Since the coefficient of x² is 2, a = 2, so

$y = 2(x + 1)(x - 5) \\ \\ y = 2( {x}^{2} - 4x + 5) \\ \\ y = 2 {x}^{2} - 8x + 10$

So, the answer is 8.

S_A_V [24]

Answer: 0.9

Step-by-step explanation:

$\mathrm{Total \ sample \ space \ $=100$} \\\mathrm{Event \ $A = \ taking \ subway \ each \ day}$$P(A)=0.85$$Event $B=$ taking taxi $\because P(B)=0.6$$$P(A \cap B)=0.55$$$

$\begin{aligned}P(A \cup B) & \Rightarrow \text { Person taking either taxi/subway } \\&=P(A)+P(B)-P(A \cap B) \\&=(0.85-0.555)+(0.6-0.55)-0.55 \\&=1.45-0.55\\&\bf{=0.9} \end{aligned}$
