Solve for A ? <br><br> Anyone willing to help me :)
GrogVix [38]

Answer:

<h2>2.2</h2>

Step-by-step explanation:

Use the cosine law:

BC^2=AB^2+AC^2-2(AB)(AC)\cos(\angle A)

We have:

BC=a\\\\AB=4\\\\AC=3\\\\m\angle A=32^o\to\cos32^o\approx0.848

Substitute:

a^2=4^2+3^2-2(4)(3)(0.848)\\\\a^2=16+9-20.352\\\\a^2=4.648\to a=\sqrt{4.648}\\\\a\approx2.2

Solve y = f(x) = (2x+1)^1/2<br><br> &amp; g(x) = x-1
snow_lady [41]

Answer:

f(x) = x = \frac{y^{2} - 1}{2}

g(x) = 1

Step-by-step explanation:

y = (2x + 1)^1/2

y^{2} = 2x + 1

y^{2} - 1 = 2x

\frac{y^{2} - 1}{2} = x

y = x - 1

y + 1 = x

A machine used to regulate the amount of a certain chemical dispensed in the production of a particular type of cough syrup can
olchik [2.2K]

Answer:

The mean value of the chemical to be added to every bottle of syrup so that the bottle wont be rejected would be = 1.41750 ml

Step-by-step explanation:

Standard deviation ( σ )= 0.250 ml

assume the required amount of chemical to be deposited in each syrup bottle to be X

Hence the distribution of X in each bottle can be represented as :

X Г N ( u , 0.250 )

for a bottle not to be rejected  :  P ( X ≤ 2 )

To determine the setting so that no more than 1% of the bottles of cough syrup prepared by this machine will be rejected we have to standardize the variable X

at X = 2 ml

\frac{x - u }{std}  = \frac{2 - u}{std}

z = \frac{2-u}{0.250} = z ----------- ( 1 )

probability for a bottle to be rejected : P( x >2 ) = 1 - P ( x ≤ 2 )

                                                                             = 0.01

attached below is a normal distribution curve showing probability values

from the curve

p( 0 < Z < z ) = 0.5 - 0.01 = 0.49  

Area = 0.49 hence from the Normal table where area = 0.49 the value of z = 2.33

Referring back to equation 1 above:  z = \frac{2-u}{0.250} = 2.33 --------- (2)

<em>u</em> = mean value that should be added so that the bottle will not be rejected

make <em>u</em> subject of the equation : u = 2 - ( 2.33 * 0.250 )

                                                       u = 1.41750

The mean value of the chemical to be added to every bottle of syrup so that the bottle wont be rejected would be = 1.41750 ml
