Step-by-step explanation:

Let's combine the like terms first, which are x^2 & -3x^2, and 3x & -4x.

x^2 -3x^2 is -2x^2. 3x -4x is -x.

The final, simplified expression would be -2x^2 -x.

if two pounds of cheese sells for $3.18, how much will three pounds of cheese cost? SHOW YOUR WORK!! plz
OleMash [197]
If two pounds of cheese sells for $3.18, how much will three pounds of cheese cost?

If two pounds of cheese are $3.18 then we must divide it by 2.

\frac{3.18}{2} =1.59<u />

Then we multiply.

1.59*3=4.77<u />

So three pounds of cheese are

$4.77<u />

Hope I helped!

An automated egg carton loader has a 1% probability of cracking an egg, and a customer will complain if more than one egg per do
vaieri [72.5K]

Answer:

a) Binomial distribution B(n=12,p=0.01)

b) P=0.007

c) P=0.999924

d) P=0.366

Step-by-step explanation:

a) The distribution of cracked eggs per dozen should be a binomial distribution B(12,0.01), as it can model 12 independent events.

b) To calculate the probability of having a carton of dozen eggs with more than one cracked egg, we will first calculate the probabilities of having zero or one cracked egg.

P(k=0)=\binom{12}{0}p^0(1-p)^{12}=1*1*0.99^{12}=1*0.886=0.886\\\\P(k=1)=\binom{12}{1}p^1(1-p)^{11}=12*0.01*0.99^{11}=12*0.01*0.895=0.107

Then,

P(k>1)=1-(P(k=0)+P(k=1))=1-(0.886+0.107)=1-0.993=0.007

c) In this case, the distribution is B(1200,0.01)

P(k=0)=\binom{1200}{0}p^0(1-p)^{12}=1*1*0.99^{1200}=1* 0.000006 = 0.000006 \\\\ P(k=1)=\binom{1200}{1}p^1(1-p)^{1199}=1200*0.01*0.99^{1199}=1200*0.01* 0.000006 \\\\P(k=1)= 0.00007\\\\\\P(k\leq1)=0.000006+0.000070=0.000076\\\\\\P(k>1)=1-P(k\leq 1)=1-0.000076=0.999924

d) In this case, the distribution is B(100,0.01)

We can calculate this probability as the probability of having 0 cracked eggs in a batch of 100 eggs.

P(k=0)=\binom{100}{0}p^0(1-p)^{100}=0.99^{100}=0.366

Find one positive and one negative angle coterminal with an angle of <img src="https://tex.z-dn.net/?f=%5Cfrac%7B11pi%7D%7B8%7D"
zaharov [31]

Answer:

see explanation

Step-by-step explanation:

Co terminal angles are angle ± 2π, that is

\frac{11\pi }{8} + 2π

= \frac{11\pi }{8} + \frac{16\pi }{8} = \frac{27\pi }{8}

and

\frac{11\pi }{8} - 2π

= \frac{11\pi }{8} - \frac{16\pi }{8} = - \frac{5\pi }{8}
