Answer: [tex]\mu=15.64[/tex]

Step-by-step explanation:

Let x be a random variable that represent the amount dispensed by a soft-drink dispensing machine which has a normal distribution with mean μ and standard deviation [tex]\sigma=[/tex] 0.155 ounce.

To find : μ such that P(X>16)=0.01

Consider  P(X>16)=0.01

[tex]P(\dfrac{X-\mu}{\sigma}>\dfrac{16-\mu}{0.155})=0.01[/tex]

Since, [tex]Z=\dfrac{X-\mu}{\sigma}[/tex]

Also, z-table , one -tailed z-value for p-value of 0.01= 2.326

Then, [tex]\dfrac{16-\mu}{0.155}=2.326[/tex]

[tex]\Rightarrow {16-\mu}=0.155\times2.326\\\\\Rightarrow {16-\mu}=0.36053\\\\\Rightarrow\ \mu=16-0.36053=15.63947\approx15.64\\\\\Rightarrow\ \mu=15.64[/tex]

A: -16 < -4

B: 40 > 8

C: -45 < 15

D: 35 > -20

E: Reverse

It should be noted that when Andre and Elena are solving this system of equations, the first step is correct but the others are wrong.

It should be noted that an equation is used.to show the relationship between the expressions that are given.

It should be noted that Andre and Elena are solving this system of equations: y=3x, y=9x−30.

This will be equated to this:

3x = 9x - 30

Collect like terms

9x - 3x = 30

6x = 30

Divide

x = 30 / 6

x = 5

Note that y = 3x = 3 × 5 = 15

Therefore, it should be noted that when the value of y is 15 and only the first step is correct.

Step-by-step explanation:

He jogged over 8 miles so he needs to stop jogging he already completed his goal.

Since one yard is equivalent to three feet, you can multiply the number of yards by 3 to convert from yards to feet. 36 feet are equal to 12 yards times 3 feet per yard. Consequently, 12 yards are equal to 36 feet.

A unit of length equivalent to 3 feet, or around 0.914 metres.

Both the US Customary and British Imperial Systems of Measurement use yards as a measure of length. Yd is its symbol. The length of medium-sized objects is frequently measured using it.

Find out what 1 Foot per centimeter is (1.5 centimeters per foot)Multiply 13 by 1.5 to find one side and 24 by 1.5 to find the other side.

The area of a shape is the amount of space on the shape.

The best approximation for the area of the figure is [tex]14 + 16.25\pi[/tex]

Start by calculating the diameter of the semicircle using the following distance formula:

[tex]d = \sqrt{(x_2 -x_1)^2 +(y_2 -y_1)^2}[/tex]

So, we have:

[tex]d = \sqrt{(-4 -3)^2 +(-2 -2)^2}[/tex]

[tex]d = \sqrt{65}[/tex]

Divide by 2, to calculate the radius

[tex]r = \frac{\sqrt{65}}{2}[/tex]

So, the area of the semicircle is:

[tex]A = \frac{\pi r^2}{2}[/tex]

This gives

[tex]A = \pi (\frac{\sqrt{65}}{2})^2[/tex]

[tex]A = \frac{65}{4}\pi[/tex]

[tex]A = 16.25\pi[/tex]

Next, we calculate the area of the triangle using:

[tex]A = 0.5 * B * H[/tex]

Where:

[tex]B = 3 -(-4)[/tex]

[tex]B = 7[/tex]

[tex]H= 2 - (-2)[/tex]

[tex]H = 4[/tex]

So, we have:

[tex]A = 0.5 * 7 * 4[/tex]

[tex]A = 14[/tex]

The area of the figure is then calculated as:

[tex]A = 14 + 16.25\pi[/tex]

Hence, the best approximation for the area of the figure is [tex]14 + 16.25\pi[/tex]

Answer: A 95% lower confidence bound for the mean capacity of this type of battery = 175.85

Step-by-step explanation:

Given: The capacities were measured for a sample : n= 120 batteries.

[tex]\overline{x}=178[/tex] and  [tex]\sigma=12[/tex]

lower confidence bound= [tex]\overline{x}-z^c\times\dfrac{\sigma}{\sqrt{n}}[/tex]

Critical z value for 9%% confidence = 1.96

So,  a 95% lower confidence bound for the mean capacity of this type of battery will be :

[tex]178-(1.96)\dfrac{12}{\sqrt{120}}\\\\=178-(1.96)(1.0954451)\\\\=(1.96)(1.0954451)\approx175.85[/tex]

Hence, a 95% lower confidence bound for the mean capacity of this type of battery = 175.85

Answer: the divergence of the vector fields at all points its defined is 0

Step-by-step explanation:

Given that;

div ( [x / (x²+ y² + z²)^1.5]i  +  [y / (x² + y² + z²)^1.5]j  +  [z / (x² + y² + z²)^1.5]k )

= d/dx [x / (x²+ y² + z²)^1.5]  +  d/dx [y / (x² + y² + z²)^1.5] +  d/dx [z / (x² + y² + z²)^1.5]

= [1 / (x²+ y² + z²)^1.5] - [3x² / (x²+ y² + z²)^2.5] + [1 / (x²+ y² + z²)^1.5] - [3y² / (x²+ y² + z²)^2.5] + [1 / (x²+ y² + z²)^1.5] - [3z² / (x²+ y² + z²)^2.5]

= [3 / (x²+ y² + z²)^1.5]  -  [(3x² + 3y² +3z²) / (x²+ y² + z²)^2.5]

= [2 / (x²+ y² + z²)^1.5]   -   [3 / (x²+ y² + z²)^1.5]  = 0

therefore the divergence of the vector fields at all points its defined is 0

Answer:

The sample size  is  [tex]n = 153664[/tex]  

Step-by-step explanation:

From the question we are told that

    The margin of error is  E  =  0.01

From the question we are told the confidence level is  95% , hence the level of significance is    

      [tex]\alpha = (100 - 95 ) \%[/tex]

=>   [tex]\alpha = 0.05[/tex]

Generally from the normal distribution table the critical value  of  [tex]\frac{\alpha }{2}[/tex] is  

   [tex]Z_{\frac{\alpha }{2} } =  1.96[/tex]

Let take the standard deviation to be [tex]\sigma = 2 \ pounds[/tex]

Gnerally the sample size is mathematically represented as

       [tex]n = [\frac{Z_{\frac{\alpha }{2} } * \sigma }{E} ]^2[/tex]

=>    [tex]n = [\frac{1.96 *2 }{0.01} ]^2[/tex]

=>    [tex]n = 153664[/tex]  

Answer:

P = - 0.1x+520

Step-by-step explanation:

Finding the demand function p ( x ) , where x is the number of the television sets sold per week.

each $25 rebate offered to the buyer, the number of sets sold will increase by 250 , hence slope = -25/250 = -1/10 Equation will be

P-390/x-1300 = -25/250

Cross multiplying

250(P-390) = -25(x-1300)

250p-97500 = -25x+32500

250p = -25x+32500+97500

250p = -25x + 130000

Divide both sides by 250

250p/250 = (25x + 130000)/250

P = - 0.1x+520

Hence, the demand function p(x) is

= - 0.1x+520
