The diameter of the ball bearings varies according to a distribution that is approximately Normal
with mean 11.5 mm and standard deviation 0.05 mm. Two ball bearings are randomly selected. Find the probability that the difference in the diameters of the two ball bearings is less than 0.06 mm.

Answers

Answer 1

Tthe probability that the difference in the diameters of the two ball bearings is less than 0.06 mm is 0.0478

How to determine the probability?

From the question, we have the following parameters that can be used in our computation:

Mean = 11.5

Standard deviation = 0.05

Let the diameters be X and Y

So, we have

P(|X - Y| < 0.06)

Using this information, we have

P(|X - Y| < 0.06) = P( -0.06 < X - Y < 0.06)

= P(X - Y < 0.06) - P(X - Y < -0.06)

= 0.0478

Hence, the probability is 0.0478

How to evaluate  the arithmetic series?

An arithmetic progression ( AP ) is a sequence of numbers such that the difference between the consecutive terms is constant.

From the given information, we can get the first term (a) and  last term (l) of the sequence by substituting n = 1  and n = 45 respectively into the given expression, (4n + 9). That is:

a = 4(1) + 9 = 13

l = 4(45) + 9 = 189

Sum of all terms in a finite AP with the first term (a) and last term (l) is given by:

S = n/2(a + l)

S = 45/2 (13+189) = 4545

Thus, the arithmetic series evaluates to

Answers

Yes, for every 6 duck decoys big lake bob carves he must give up 20 fishing lures.

Production possibility schedule:-

Fish lures:

Fish lures in one week = 100

lures in a day = 20

So, 100-20 = 80

80 - 20 = 60

60 - 20 = 40

40 - 20 = 20

20 - 20 = 0

Duck decoys:

Duck in one day = 0

So, 0 + 6 = 6

6 + 6 = 12

12 + 6 = 18

18 + 6 = 24

24 + 6 = 30

number of duck decoy in a week = 30

Hence, For every 6 duck decoys Bob carves 20 lures.

The inner integral is to be integrated with respect to y is:

∫(6xy[tex]\sqrt{(x^2 + y^2)}[/tex])dy from 0 to 1 = [3y([tex]x^2 + y^2[/tex][tex])^{(3/2)}[/tex])] from 0 to 1

= 3(1)*([tex]x^2[/tex] + 1[tex])^{(3/2)}[/tex]

= 3([tex]x^2[/tex] + 1[tex])^{(3/2)}[/tex]

Now, we can use this result as the inside function to evaluate the outer integral with respect to x.

The outer integral is to be integrated with respect to x is:

∫(3([tex]x^2[/tex] + 1[tex])^{(3/2)}[/tex])dx from 0 to 3

Answers

An Experimental study is used. As subjects were randomly assigned to two groups, and one group was given an herb and the other group a placebo. after months, the numbers of respiratory tract infections each group had were compared.

Experimental investigations or study involve introducing an intervention and observing its results. Typically, volunteers in experimental research are grouped randomly, or by chance.

During a randomized controlled trial (RCT), participants are divided into two or more groups at random. While the control group is given nothing or a placebo, the intervention group is given the new drug, for example. The outcome of each group is then investigated by the researchers. The intervention can thus be blamed for any variations in the results.

Whereas, Observational study is the Studies in which researchers look at how a risk factor, diagnostic test, treatment, or other intervention affects a population without attempting to alter who is or is not exposed to it.

Hence, it is experimental study.

What is the ratio in simplest form?

A ratio is the number representing a comparison between two named things.

It also refers to the relative magnitudes of two quantities usually expressed as a quotient.

For instance, if there are 12 students in a class which includes 8 girls and 4 boys,

The ratio of girls to all students = 8 : 12

= 8/12

= 2/3

= 2 : 3

The ratio of boys to girls = 4 : 8

= 4/8

= 1/2

= 1 : 2

The ratio of all students to boys = 12 : 4

= 12/4

= 3/1

= 3 : 1

Hence,

People = 6 : 18

= 6 / 18

= 3 / 9

= 1/3

= 1 : 3

Benches = 3 : 12

To convert feet per second to yards per minute, we need to multiply the value in feet per second by the conversion factor of 1 yard/3 feet and then divide the result by the conversion factor of 1 minute/60 seconds.

12 ft/sec = (12 ft/sec) * (1 yard/3 feet) * (1 min/60 sec) = (12*1/3) * (1/60) = 4/5 = 0.8.

Therefore  , solution of ratio problem is 5760 m & 5.76 km, respectively, are the distances covered per hour for the two halves.

What are the application proportion and ratio?

As a/b, a ratio shows the  variable relationship between two numbers. When two ratios are equal, as when a/b = c/d, we get a proportion. Mathematical issues involving the unit numbers of the quantities can be resolved using ratio and proportion.

Here,

The ratio approach can be used to solve the above problem as follows:

(A) A 1.6 m/s walking speed is typical.

The calculation for the speed in meters per hour is

1/3600 of an hour is equal to one second.

Take the following 1.6:3600 ratio as an example:

1.6 ÷ 1/3600

= 3600 × 1.6

= 5760

The typical walking speed is 1.6 m/s.

It implies a speed of 1.6 meters per second.

Now, 1 m equals 1/1000 km.

=> 1.6 m = 1.6/1000 km

Moreover, one second is equal to three thousand six hundredths of an hour.

As a result, the distance traveled in kilometers per hour can be calculated by using the following ratio:

1.6/1000 ÷ 1/3600

= (3600 × 1.6)/1000

= 5.76

Therefore, 5760 m and 5.76 km, respectively, are the distances covered per hour in meters and kilometers.

What is the value of SS (sum of squared deviations) for the following population? Population: 1, 1, 1, 5
A)3
B)7
C)12
D)28

Answers

The value of sum of squared deviations is 12.

The given population is 1,1,1,5

First find the mean:

Mean is the average of the given numbers and is calculated by dividing the sum of given numbers by the total number of numbers.

Mean = (Sum of all the observations/Total number of observations)

Mean=[tex]\frac{1+1+15}{4}=\frac{8}{4}=2[/tex]

The Mean is 2.

The symbol of mean is usually given by the symbol [tex]\bar x[/tex]. The bar above the letter x, represents the mean of x number of values.

[tex]\bar X[/tex] = (Sum of values ÷ Number of values)

Subtract the mean from each observation and square the resulting difference. Then add the differences to get SS:

SS=[tex](1-2)^{2}+ (1-2)^{2}+ (1-2)^{2}+ (5-2)^{2}[/tex]

[tex]=1+1+1+(3)^{2} \\=3+9\\=12[/tex]

Therefore, the value of SS is 12.

Seven less than the product of 9 and a number equals 8. Use the variable b for the unknown number

Answers

The equation formed by the sentence is 9b - 7 = 8.

What is equation ?

The definition of an equation in algebra is a mathematical statement that demonstrates the equality of two mathematical expressions. For instance, the equation 3x + 5 = 14 consists of the two equations 3x + 5 and 14, which are separated by the 'equal' sign.

A mathematical statement known as an equation is made up of two expressions joined together by the equal sign. A formula would be 3x - 5 = 16, for instance. When this equation is solved, we discover that the value of the variable x is 7.

A mathematical expression with an equals sign is referred to as an equation. Algebra is widely used in equations. When performing calculations but unsure of the precise amount, algebra is used.

Let the variable be b

By the given sentence we get the equation

9b - 7 = 8

What is consecutive integers?

Consecutive integers or consecutive numbers are the terms used to describe the sequence of numbers. In this case, the integers are arranged in ascending order from smallest to highest. The following are a few examples: -4, -3, 2, 1, 0, 1, 2, 3, 4.

Given:

The left and right page numbers of an open book are two consecutive interfere whos sum is 361.

We have to find the page numbers.

Let

The left page number is n.

The right page number is n + 1.

As the sum of numbers is 361.

⇒ n + (n + 1) = 361

         2n + 1 = 361

              2n = 360

                n = 180

Hence, the left page number is 180 and the right page number is 181.
