A baseball player made 9 errors in 60 games. How many errors would we expect the player to make in 100 games

The sum of the given two positive integers is 9.

According to the question,

We have the following information:

The product of two positive integers is 18. the positive difference of these two integers is 3.

Now, let's take the first positive integer (larger one) to be x and the second positive integer to be y.

xy = 18 ...(1)

x-y = 3

x = 3+y

Putting this value in equation 1:

(3+y)y = 18

[tex]y^{2} +3y-18 = 0[/tex]

[tex]y^{2}[/tex]+6y-3y-18 = 0

y(y+6)-3(y+6) = 0

(y+6) (y-3) = 0

y-3 = 0 and y+6 = 0

y = 3 or y = -6

Now, the number is positive so it will be 3.

Putting this value in equation 1:

xy = 18

3x = 18

Dividing by 3 on both sides of the equation:

x= 18/3

x = 6

Sum of integers = 3+6

Sum of integers = 9

Hence, the sum of the given two positive integers is 9.

In a simple linear regression model , if we change the input variable by 1 unit , output variable will change by its slope.

What is linear regression?

According on the value of another variable, a variable's value can be predicted using a linear regression analysis. The dependent variable is the one you're trying to forecast. The term "independent variable" refers to the variable you are using to forecast the value of the other variable.

For linear regression

Y=a + bx + error

If we neglect error

then Y=a + bx.

If x increases by 1

then Y = a +b(x+1) which implies

Y=a + bx + b.

So Y increases by its slope.

Hence their is an increase in the slope in y.

The values of c in the given equation, 19 = | 5c - 4 |, are c = -3 and c = 4 3/5

From the question, we are to solve the given equation for all values of c

The given equation is

19 = | 5c - 4 |

From this equation, we can write that

19 = (5c - 4) and 19 = -(5c - 4)

Solving the first equation

19 = (5c - 4)

19 = 5c - 4

Add 4 to both sides of the equation

19 + 4 = 5c - 4 + 4

23 = 5c

Divide both sides by 5

23/5 = 5c/5

4 3/5 = c

Therefore,

c = 4 3/5

Solving the second equation

19 = -(5c - 4)

19 = -5c + 4

Subtract 4 from both sides of the equation

19 - 4 = -5c + 4 - 4

15 = -5c

Divide both sides by -5

15/-5 = -5c/-5

-3 = c

Therefore,

c = -3

Hence, the values of c are -3 and 4 3/5

If water is being pumped into the trough at 2 cubic feet per minute, then the water level rising (in feet per minute) when h is 1.6 foot deep is 0.1 feet cubic per minute.

Suppose that we have a function y = f(x), and wish to find the rate of change of y with respect to a third variable t, where we do not have y expressed explicitly in terms of t. We use the chain rule in differentiation to find this rate of change in a process called implicit differentiation.

                     dy/dt = dy/dx × dx/dt

If base is equal to the height, by similar triangles:

Volume v = base x height x length/2

Therefore,  

dv/dt = 12hdh/dt

What is an Equation of a line?

The equation of a line is expressed as y = mx + b where m is the slope and b is the y-intercept

And y - y₁ = m ( x - x₁ )

y = y-coordinate of second point

y₁ = y-coordinate of point one

m = slope

x = x-coordinate of second point

x₁ = x-coordinate of point one

The slope m = ( y₂ - y₁ ) / ( x₂ - x₁ )

Given data ,

Let the number of soda bottles the machine can make in 1 minute be = y

Now , the equation is

Let the first point in the graph be A ( x₁ , y₁ )

The value of A ( x₁ , y₁ ) = A ( 3 , 48 )

Let the second point in the graph be B ( x₂ , y₂ )

The value of B ( x₂ , y₂ ) = A ( 7 , 112 )

Now , the slope of the line joining the points can be found out from the equation of slope

Slope m = ( y₂ - y₁ ) / ( x₂ - x₁ )

So , the slope of the point is m = steep of the line or inclination

Slope m = y / x

Substituting the values for x and y , we get

Slope m = 48 / 3

Slope m = 16

Therefore , the equation of line will be y = mx + c

y = 16x

Now , there are 60 seconds in a minute

So , 1 minute = 60 seconds

Substituting the value of x = 60 in the equation , we get

y = 16x

y = 16 x 60

y = 960 bottles

Therefore , the value of y = 960

Hence , The number of soda bottles the machine can make in each minute is 960 bottles

X - Binomial(n = 130, p = 0.5)

Binomial can be approximated to normal with: μ = np = 130*0.5 = 65

σ = √np(1 − p) - = √130* (0.5)(1 − 0.5)

σ = 5.7

P(55 ≤ X ≤ 69 )

Since we are approximating a discrete binomial distribution by continuous normal distribution, values between 54.5 and 68.5 both approximate to 55. Thus, "between 55 and 69" corresponds to continuous normal distribution with P(54.5 < X 68.5) after continuity correction.

Normal Distribution, x₁ = 54.5, x2 = 68.5, µ = 65, σ = 5.7

We convert this to standard normal using z =

z₁ = 54.5-65/ 5.7 ≈ - 1.84

z₂ = 68.5-65/ 5.7  ≈ 0.614

P(54.5 < X < 68.5) = P(- 1.84 < Z < 0.614)

= P(Z < 0.614) − P(Z <- 1.84)

= 0.7291 - 0.0329   (from z-table)

The equation 8x - 4y = -4 have y as the subject to be equal to 2x + 1 expresses in terms of x.

To solve for y in the equation 8x - 4y = -4, we must make y the subject and it should be positive as follows;

8x - 4y = -4

add 4y to both sides

8x - 4y + 4y= -4 + 4y

8x = - 4 + 4y

also to make y the subject;

- 4 + 4y = 8x

add 4 to both sides

- 4 + 4 + 4y = 8x + 4

4y = 8x + 4

factorize the right hand side

4y = 4(2x + 1)

divide through by the coefficient of y

4y/4 = [4(2x + 1)]/4

y = 2x + 1

Hence, the equation 8x - 4y = -4 has y = 2x + 1

The confidence interval for the given ANOVA test to calculate the average typing speed be, (144.83 , 155.17) and the margin of error of the poll be, ±5.17

On Subtracting 1 from your sample size, we get

150 – 1 = 149.

On Subtracting confidence level from 1, and then divide by two.

(1 – .95) / 2 = 0.025

Now, df = 149 and α = 0.025

from the table at df = 149 we got 2.262.
