A bottling company uses a filling machine to fill plastic bottles with cola. The bottles are supposed are supposed to contain 300m. In fact, the contents vary according to a Normal Distribution with mean of 298 mL and a standard deviation of 3 mL. (a) What is the probability that an individual bottle contains less than 295 mL? Show your work. (b) What is the probability that the mean contents of six randomly chosen bottles is less than 295 mL? Show your work.

Answers

Answer 1

Answer:

0.15866 ; 0.0071627

Step-by-step explanation:

Given that:

Mean (m) = 298

Standard deviation (s) = 3

A.) P(x < 295)

Using the relation to obtain the standardized score (Z) :

Z = (x - m) / s

Z = (295 - 298) / 3 = - 1

p(Z < - 1) = 0.15866 ( Z probability calculator)

B.)

Z = (x - m) / s /sqrt(n)

Z = (295 - 298) / 3/sqrt(6) = −2.449489

p(Z < - 2.449) = 0.0071627 ( Z probability calculator)

Answer 2
The probability will be:(a) 0.15866(b) 0.007163

Given values are:

Mean,

m = 298

Standard deviation,

s = 3

(a)

P(x < 295)

The standardized score will be:

→ [tex]Z = \frac{(x-m)}{s}[/tex]

By substituting the values, we get

      [tex]= \frac{(295-298)}{3}[/tex]

      [tex]= \frac{-3}{3}[/tex]

      [tex]= -1[/tex]

Now,

By using the Z probability calculator, we get

→ [tex]p(Z< -1) = 0.15866[/tex]

(b)

The standardized score will be:

→ [tex]Z = \frac{x-m}{\frac{s}{\sqrt{n} } }[/tex]

By putting the values,

      [tex]= \frac{295-298}{\frac{3}{\sqrt{6} } }[/tex]

      [tex]= -2.449489[/tex]

Now,

→ [tex]p(Z < -2.449)= 0.007163[/tex]

Thus the responses above are correct.

Last week, the number of type 2 cabinets produced exceeded twice the number of type 1 cabinets produced by 20. If x is the number of type 1 cabinets produced and y is the number of type 2 cabinets produced, the system of equations that represents this situation is x + y = 110 and y = 2x + 20.?

Answers

Step-by-step explanation:

Let x is the number of type 1 cabinets produced and y is the number of type 2 cabinets produced.

The total no of cabinets are 100

Equation will be : x+y = 110

We can write it as : y = 110-x ...(1)

Last week, the number of type 2 cabinets produced exceeded twice the number of type 1 cabinets produced by 20.

Equation will be : y = 2x + 20 ...(2)

Put the value of y from equation (1) into equation (2).

110-x = 2x + 20

Combining like terms,

110-20 = 2x+x

90 = 3x

x = 30

Put the value of x in equation (1) :

y = 110-30

y = 80

Hence, there are 30 cabinets of type 1 and 80 cabinets of type 2.

In Exercises 27 and 28, find the domain of the function
represented by the graph. Determine whether the
domain is discrete or continuous. Explain.

Answers

                                             Question 27

The graph on question 27 indicates that there are three points with the locations such as:

(2, 6)(4, 12)(6, 18)

In other words, there are three points that lie on the graph with the x-values such as:

{(2, 6), (4, 12), (6, 18)}

We know that the domain includes the set of x-values.

Hence, the domain of the function is:

Domain: {2, 4, 6}

Since the points are not connected between them. In other words, there is not a continuous line.

Thus, the function represented on the graph has a discrete domain.

                                        Question 28

The graph on question 27 indicates that the line segment with the end-points (0, 25) and (7, 20).

Since there is a continuous line between the points from x = 0 to x = 7.

Thus, the domain of the line function is:

Domain: {0, 1, 2, 3, 4, 5, 6, 7}

As the line segment is a continuous line. Thus, the domain is continuous.

HELP!!!! I have never seen this. I will award big brain.​

Answers

Step-by-step explanation:

Angles APD, DPC and CPB are supplementary. (Angles on a straight line)

Therefore Angle APD + Angle DPC + Angle CPB = 180°.

Since Angle DPC = 90° (Right angle),

Angle APD + Angle CPB = 180° - 90° = 90°.

=> (7x + 1) + (9x - 7) = 90

=> 16x - 6 = 90

=> x = 6

Hence arc measure of minor arc AD

Ay can anybody please help me with this question !

Answers

Answer: a = 45°

Step-by-step explanation:

The measure of∠PSR is given: 90°

Given PS = RS, this is an isosceles triangle. so measure of ∠SPR, labeled "a" is equal to the measure of ∠SPR.  

The total of all angles in a triangle is 180. So subtract 90, then divide by 2.

180-90 = 90

90/2 = 45

a = 45°

If "b" is supposed to be the measure of ∠SRQ, that is 15°  The larger triangle is equilateral; all the angles are 60°. 60 - 45 = 15

7.5 cups of sugar to make 14 dozen cookies. To the nearest hundredth, what is the rate of cups of sugar per cookie?

Answers

Answer:

0.54 There you go!

There are 168 cookies. 14 times a dozen (12) is 168.

The ratio of cups of sugar to cookies is 7.5 to 168.

If you want to find the cups of sugar you need for 168, divide 7.5 and 168 by 168.

168/168=1

7.5/168 is about 0.04.

The cups of sugar you use for one cookie is 0.04.

The value of x.

Solution:

We have,

[tex]5^2\times 5^{x-5}=625[/tex]

It can be written as

[tex]5^2\times 5^{x-5}=5\times 5\times 5\times 5[/tex]

Using property of exponents, we get

[tex]5^{2+x-5}=5^4[/tex]            [tex][\because a^m\times a^n=a^{m+n}][/tex]

[tex]5^{x-3}=5^4[/tex]

Comparing the exponents on both sides, we get

[tex]x-3=4[/tex]

Adding 3 on both sides, we get

[tex]x=4+3[/tex]

[tex]x=7[/tex]

total trip to be completed by Tora, = 320 miles

distance completed by Tora, = 120 miles

The fraction of the race that Tora has completed is given as;

[tex]= \frac{distance \ completed}{total \ distance} \\\\= \frac{120}{320}\\\\= \frac{12}{32} \ (divide \ both \ numerator \ and \ denominator \ by \ 4)\\\\= \frac{3}{8}[/tex]

Shawnda spent $259.20 on a scooter. This was 80% of her budget for a new scooter. How much was the total budget?

Answers

x * 0,8 = 259,2 <=>

x = 258,2/0,8 <=>

x = 322,75

The total budget was 322,75$

The total budget was = $324

The percentage of budget spent = 80%

The cost of 80% of budget spent on scooter = $259.20

But the percentage of total budget = 100%

Therefore the cost of total budget =

[tex] \frac{100 \times 259.20}{80} [/tex]

[tex] \frac{25920}{80} [/tex]

= 324

Therefore the cost of the total budget = $324

Answer:

Washing Cars: $33

Clearing Tables: $91

Step-by-step explanation: Multiply 11 by 3, and multiply 13 by 7. I hope I helped!

Step-by-step explanation:

for every 1 hour she works she gets 11 dollars washing the cars, so you multiply the number of hours by the amount of money she gets each hour. Like so,

11 x 3 = 33, so 33 dollars from washing cars

next - 13 x 7 = 91 dollars from house cleaning

add together the amount of each so, 33 + 91 = 124, 124 is the answer.

what does y equal and how did you solve it?

Answers

Answer:

y=2x+5

Step-by-step explanation:

Let's solve for y.

−2x+y=5

Step 1: Add 2x to both sides.

−2x+y+2x=5+2x

y=2x+5

Answer:

y = 2x + 5

Step-by-step explanation:

-2x + y = 5 or y -2x = 5

We want what y equals so we need to isloate it. To do this, we need to add2x to both sides. This will cancel the 2x on the left side and now we have y alone. Remember, you have to do it to both sides. Therefore:

y = 2x + 5

Note: This equation is in slope-intercept form, y= mx + b

If this was the equation of a line:

  m (slope) = 2

  b (y-intercept) = 5
