If a=15 and b=6, then 9a²-48ab+64b²=?

photoshop1234 [79]

Answer:

Step-by-step explanation:

Value of 'a' = 15

Value of 'b' = 6

Simplifying the expression given in question,

$9a^{2} -48ab+64b^{2}$

$=> (3a)^{2} - 2*3a*8b+(8b)^{2}$

$=>(3a-8b)^{2}$

Putting 'a' & 'b' in above expression ,

$(3a-8b)^{2} = (3*15-8*6)^{2} = (45-48)^{2} = (-3)^{2} =9$

Find f(1) if f(x)=2x^3+x^2-3x-1

luda_lava [24]

Answer:

The answer is -1

Step-by-step explanation:

f(x) = 2x³ + x² - 3x - 1

f(1) = 2(1)³ + (1)² - 3(1) - 1

f(1)= 2 + 1 - 3 - 1

f(1)=3-3-1

f(1)=0-1

f(1)= -1

Thus the answer is -1 ....

Serga [27]

Answer:

0.0159

Step-by-step explanation:

Given that a common practice of airline companies is to sell more tickets for a particular flight than there are seats on the plane, because customers who buy tickets do not always show up for the flight.

Here if X is the no of persons that do not show up, then X is binomial as each trial is independent with p = 0.04 and n =150 (no of tickets sold)

The plane is overbooked if more than 150 show up

i.e. less than 2 do not show up

Hence the probability that the airline overbooked this flight

= $P(X$
