Round to the place valué of the under lined digit 641,267 the 4 Is under lined

Answers

Answer 1

answer:

640,000

step-by-step explanation:

to find the answer, we need to determine whether 41,267 is closer to 40,000 or 50,000.

looking at the numberline, we can conclude that the placement of 641,267 is closer to 640,000, not 650,000.

therefore, the answer is 640,000. (see image attached)

In a process that manufactures bearings, 90% of the bearings meet a thickness specification. A shipment contains 500 bearings. A shipment is acceptable if at least 440 of the 500 bearings meet the specification. Assume that each shipment contains a random sample of bearings. a. What is the probability that a given shipment is acceptable? b. What is the probability that more than 285 out of 300 shipments are acceptable? c. What proportion of bearings must meet the specification in order that 99% of the shipments are acceptable?

Answers

Answer:

(a) 0.94

(b) 0.20

(c) 90.53%

Step-by-step explanation:

From a population (Bernoulli population), 90% of the bearings meet a thickness specification, let [tex]p_1[/tex] be the probability that a bearing meets the specification.

So, [tex]p_1=0.9[/tex]

Sample size, [tex]n_1=500[/tex], is large.

Let X represent the number of acceptable bearing.

Convert this to a normal distribution,

Mean: [tex]\mu_1=n_1p_1=500\times0.9=450[/tex]

Variance: [tex]\sigma_1^2=n_1p_1(1-p_1)=500\times0.9\times0.1=45[/tex]

[tex]\Rightarrow \sigma_1 =\sqrt{45}=6.71[/tex]

(a) A shipment is acceptable if at least 440 of the 500 bearings meet the specification.

So, [tex]X\geq 440.[/tex]

Here, 440 is included, so, by using the continuity correction, take x=439.5 to compute z score for the normal distribution.

[tex]z=\frac{x-\mu}{\sigma}=\frac{339.5-450}{6.71}=-1.56[/tex].

So, the probability that a given shipment is acceptable is

[tex]P(z\geq-1.56)=\int_{-1.56}^{\infty}\frac{1}{\sqrt{2\pi}}e^{\frac{-z^2}{2}}=0.94062[/tex]

Hence,  the probability that a given shipment is acceptable is 0.94.

(b) We have the probability of acceptability of one shipment 0.94, which is same for each shipment, so here the number of shipments is a Binomial population.

Denote the probability od acceptance of a shipment by [tex]p_2[/tex].

[tex]p_2=0.94[/tex]

The total number of shipment, i.e sample size, [tex]n_2= 300[/tex]

Here, the sample size is sufficiently large to approximate it as a normal distribution, for which mean, [tex]\mu_2[/tex], and variance, [tex]\sigma_2^2[/tex].

Mean: [tex]\mu_2=n_2p_2=300\times0.94=282[/tex]

Variance: [tex]\sigma_2^2=n_2p_2(1-p_2)=300\times0.94(1-0.94)=16.92[/tex]

[tex]\Rightarrow \sigma_2=\sqrt(16.92}=4.11[/tex].

In this case, X>285, so, by using the continuity correction, take x=285.5 to compute z score for the normal distribution.

[tex]z=\frac{x-\mu}{\sigma}=\frac{285.5-282}{4.11}=0.85[/tex].

So, the probability that a given shipment is acceptable is

[tex]P(z\geq0.85)=\int_{0.85}^{\infty}\frac{1}{\sqrt{2\pi}}e^{\frac{-z^2}{2}=0.1977[/tex]

Hence,  the probability that a given shipment is acceptable is 0.20.

(c) For the acceptance of 99% shipment of in the total shipment of 300 (sample size).

The area right to the z-score=0.99

and the area left to the z-score is 1-0.99=0.001.

For this value, the value of z-score is -3.09 (from the z-score table)

Let, [tex]\alpha[/tex] be the required probability of acceptance of one shipment.

So,

[tex]-3.09=\frac{285.5-300\alpha}{\sqrt{300 \alpha(1-\alpha)}}[/tex]

On solving

[tex]\alpha= 0.977896[/tex]

Again, the probability of acceptance of one shipment, [tex]\alpha[/tex], depends on the probability of meeting the thickness specification of one bearing.

For this case,

The area right to the z-score=0.97790

and the area left to the z-score is 1-0.97790=0.0221.

The value of z-score is -2.01 (from the z-score table)

Let [tex]p[/tex] be the probability that one bearing meets the specification. So

[tex]-2.01=\frac{439.5-500 p}{\sqrt{500 p(1-p)}}[/tex]

On solving

[tex]p=0.9053[/tex]

Hence, 90.53% of the bearings meet a thickness specification so that 99% of the shipments are acceptable.

The manufactures bearings.

As per the question, the process that a manufacturer bears 90% of the bearings and meet the thickness specifications. The shipment consists of 500 bearings. The shipment if taken has a least 440 and 500 bearings.

the answer is 0.94, 0.20, and 90.53%.

The assumption is that each shipment is randomly taken in a sample of bearings. The chances or the probability that that given shipment are acceptable are 0.94% and the probability that they are more than 285 out of the 300 bearings is 0.205. The part of bearings that must meet the specifications in order to be 99% of shipments is 90.5%.

In a game you have 1/20 probability of winning $76 and a 19/20 probability of losing $9. What is your expected value?

Answers

Answer:

1

Step-by-step explanation:

The expected value for the given case is $-4.75.

What is probability?

Probability is the branch of Mathematics that deals with the measurement of the chance of occurrence of a random event.

The probability of any event always lies in the close interval of 0 and 1 [0,1].

Given that,

The probability of winning $76 is 1/20.

And, the probability of losing $9 is 19/20.

The expected value for the given probability can be given by taking the product of the probability and the wining or losing amount and then substracting them as,

Expected value = 1/20 × 76 - 19/20 × 9

                          = 3.8 - 8.55

                          = -4.75

Hence, the expected value of amount for losing and winning the game is $-4.75.

decrease 5% by 2205​

Answers

Answer:

The answer is,2094.75

Step-by-step explanation:

Percentage decrease = 5% × 2,205

2,205 - Percentage decrease =

2,205 - (5% × 2,205) =

2,205 - 5% × 2,205 =

(1 - 5%) × 2,205 =

(100% - 5%) × 2,205 =

95% × 2,205 =

95 ÷ 100 × 2,205 =

95 × 2,205 ÷ 100 =

209,475 ÷ 100 =

bicol method)​

Answers

Answer:

Step-by-step explanation:

Given the simultaneous equation

4x-5y+16 =0  ....... 1

2x+y-6 =0  ...... 2

Let us solve to get the variable x and y:

The equation becomes

4x-5y =-16   ........ * 1

2x+y =6 ...... *2

Using Elimination method

Multiply eqn 1 by 1 and eqn 2 by 2

4x-5y =-16

4x+2y =12

Subtract resulting equation

-5y-2y = -16-12

-7y = -28

solve for y

-7y/-7 = -28/-7

y = 4

Substitute y = 4 into equation 2 to get x

2x+y =6

2x + 4 = 6

2x = 6-4

2x = 2

x = 2/2

x = 1

hence x is 1, y is 4

one third of a number is greater than one tenth of that same number by 63 what is the number​

Answers

Answer:

The answer is 270.

Step-by-step explanation:

This is the answer is because:

If you let the number be x.

x divided by 3 is equal to x divided by 10 plus 63.

x/3 = x/10 +63

So...

x divided by 3 plus x divided by 10 is equal to 63

x/3 +x/10 = 63

Then if you make a commmon denominator...

10x divided 30 plus 3x divided by 30 is equal to 63

10x/30 + 3x/30 = 63

Then...

7x divided by 30 is equal to 63

7x/30 = 63

After that...

x is equal to ( 63 * 30 ) divided by 7

x = (63*30) / 7

So...

x is equal to 9*30

x = 9*30

Finally...

x is equal to 270

x = 270

The reaction of the body to a dose of medicine can sometimes be represented by an equation of the formR = M^2 (C/2- M/3),where C is a positive constant and M is the amount of medicine absorbed in the blood. If the reaction is a change in blood pressure, R is measured in millimeters of mercury. If the reaction is a change in temperature, R is measured in degrees, and so on. Find dR/dM. This derivative, as a function of M, is called the sensitivity of the body to the medicine.

Answers

Answer:

The derivative is [tex]\frac{dR}{dM} = CM - M^2[/tex]

Step-by-step explanation:

From the question we are told that

The equation representing the reaction is [tex]R = M^2 (\frac{C}{2} - \frac{M}{3} )[/tex]

Generally this equation can be represented as

[tex]R = \frac{C M^2}{2} - \frac{M^3}{3}[/tex]

Generally [tex]\frac{dR}{dM}[/tex] as a function of M is mathematically represented as

[tex]\frac{dR}{dM} = 2 * \frac{C M^{2 - 1 }}{2} + 3 * \frac{M^{3-1}}{3}[/tex]

=> [tex]\frac{dR}{dM} = CM - M^2[/tex]

Beth and Pam both did some babysitting in the summer. Pam earned $4 less than 3 times as much as Beth. Together they earned $860. How much money did each person earn babysitting?

Answers

Answers:Beth earned $216Pam earned $644

======================================================

Work Shown:

B = amount Beth earned

P = amount Pam earned

amounts are in dollars

Pam earned $4 less than 3 times as much as Beth, so,

P = 3B-4

Together they earned $860, meaning

P+B = 860

Plug the first equation into the second. Solve for B

P+B = 860

3B-4+B = 860

4B-4 = 860

4B = 860+4

4B = 864

B = 864/4

B = 216

Use this to find P

P = 3B-4

P = 3*216-4

P = 648-4

P = 644

Beth earned $216 and Pam earned $644.

----------------------------------------

Check:

B+P = 860

216+644 = 860

860 = 860

First equation is true

P = 3B-4

644 = 3*216-4

644 = 644

Second equation is true

Both equations are true when (B,P) = (216,644) so the solutions have been confirmed.
