Help me pls i really dk
kondaur [170]
I think its easier to work out part (c) first:-

People who liked anything except burger  = 3/8 + 1/4 + 1/5 =  33/40

So the fraction who liked burgers = 7/40.

7/40 of the total liked burgers   so total people surveyed = (40/7) * 126 =  720

ANswer to c is 720.

a) Number who liked  chicken and laksa = (3/8 + 1/4) * 720  =  450 Answer

b)  Number who liked pasta =  1/5 * 720  =  144

Therefore  144-126  =  18 more people liked pasta than burger , Answer.

Whoops i forgot to read the lesson :P 30 points
andriy [413]

Step-by-step explanation:

I'll do 2.

Alright,Alex let say we have factored a quadratic into two binomial, for example

(5x + 3)(6x - 4)

If we set both of those equal to zero

(5x + 3)(6x + 4) = 0

We can used the zero product property in this case to find the roots of the quadratic equation.

This means that

if  \: ab = 0 \: then \: a = 0 \: and \: b = 0

This means we set each binomal equal to zero to find it root.

5x + 3 = 0

5x =  - 3

x =  -  \frac{3}{5}

6x + 4 = 0

6x =  - 4

x =  -  \frac{2}{3}

So our roots are negative 3/5 and negative 2/3 using zero product property

Sin cos and tan help
Nikitich [7]
Sin(B) = opp/hyp = 32/40 = 0.8
cos(B) = adj/hyp = 24/40 = 0.6
tan(B) = opp/adj = 32/24 = 1.33 (repeating)

suppose point p(4,-9) is translated accoring to the rule (x,y). (X+3,Y-2) what are the coordinates of p? explain
mel-nik [20]

Answer:

(7,-11)

Step-by-step explanation:

We are given the rule of: (x,y)\rightarrow(x+3,y-2).

Apply the rule to point P:

(4,-9)\rightarrow(4+3,-9-2)\rightarrow\boxed{(7,-11)}

P' should be (7,-11).

Hope this helps.
