mestny [16]

Answer: Option C

AC = 2\pi

Step-by-step explanation:

The arc length is calculated as

L = \theta * R

Then

AC = \theta * R

We know that

BC = 24\ ft

If BC is the diameter of the circumference then the radius R is:

R = \frac{BC}{2}

R = \frac{24}{2}

R = 12\ ft

Now we convert the anglo from degrees to radians\theta= 30\° * \frac{\pi}{180\°}\\\\\theta=\frac{1}{6}\pi

Finally

AC = \frac{1}{6}\pi * 12

AC = 2\pi

Question Help When purchasing bulk orders of​ batteries, a toy manufacturer uses this acceptance sampling​ plan: Randomly select
horrorfan [7]

Answer:

The probability is P(X  \le 2 ) = 0.9072

The company will accept 90.72% of the shipment and will reject (100 -90.72) =  9.2\% of the shipment , so many of the shipment are rejected

Step-by-step explanation:

From the question we are told that

   The  sample size is  n =  36

   The  proportion that did not meet the requirement is  p =  0.03

Generally the probability that the whole shipment is accepted is equivalent to the probability that there is at most 2 batteries that do not meet the requirement , this is mathematically represented as

     P(X  \le 2 ) = [ P(X =  0 ) +  P(X =  1 ) + P(X = 0)]

=>   P(X  \le 2 ) = [ [^{n}C_0 * (p)^{0} *(1-p)^{n-0} ] +  [^{n}C_1 * (p)^{1} *(1-p)^{n-1} ] +  [^{n}C_2 * (p)^{2} *(1-p)^{n-2} ]]

Here C stands for Combination (so we will be making the combination function in our  calculators )

So

=> P(X  \le 2 ) = [ [^{36}C_0 * (0.03)^{0} *(1-0.03)^{36-0} ] +  [^{36}C_1 * (0.03)^{1} *(1-0.03)^{36-1} ] +  [^{36}C_2 * (0.03)^{2} *(1-0.03)^{36-2} ]]

=> P(X  \le 2 ) = [ [1 * 1 * 0.3340  ] +  [36* 0.03 *0.3444 ] +  [630 * 0.0009 *(0.355 ]]

=>P(X  \le 2 ) = 0.9072

The company will accept 90.72% of the shipment and will reject (100 -90.72) =  9.2\% of the shipment , so many of the shipment are rejected

lbvjy [14]

Answer:

4 {x}^{2}  - 2x + x = 5 {x}^{2}  + 2x \\ 4 {x}^{2}  - x = 5 {x}^{2}  + 2x \\ 4 {x}^{2}  - 5 {x}^{2}  = 2x + x \\  - 1 {x}^{2}  = 3x \\  - x = 3 \\ x =  - 3 \\ thank \: you
