In order to determine an interval for the mean of a population with unknown standard deviation, a sample of 58 items is selected. The mean of the sample is determined to be 36. The associated number of degrees of freedom for reading the t value is :

a. 35.

b. 57.

c. 36.

d. 58.

Answer: Option b. 57 is the correct answer.

Step-by-step explanation:

Given that;

sample size n = 58

sample mean x" = 36

degrees of freedom for reading the t value is = ?

we know that;

Degree of freedom df = n - 1

where n is the sample size

so we substitute

Degree of freedom df = 58 - 1

Degree of freedom df = 57

Therefore Option b. 57 is the correct answer.

The production rate of a steel factory is declining due to old machinery. Over the last eight days production has dropped by 1.2 tons. What is the average rate of change in steel production over the eight days? Express the answer in tons per day.

A. +1.2
B. -1.2
C. +0.15
D. -0.15

Answers

Answer:

option D.

Step-by-step explanation:

average rate of change in steel production over the eight days=-0.15 tons per day

Step-by-step explanation:

The production rate of a steel factory is declining due to old machinery. Over the last eight days production has dropped by 1.2 tons.

Production is dropped by 1.2 tons, so its negative

Average rate of change = Change in production / number of days

Average rate of change = -1.2/ 8= -0.15

so sorry -0.15

-¼ ( x + 2) + 5 = - x

( this is a multi-step equation)

Answers

The value of x after simplfication of equation -¼ ( x + 2) + 5 = - x is -6.

Consider the equation,

( - 1 / 4 ) × ( x + 2 ) + 5 = - x

Now,

( - x / 4 ) + ( - 2 / 4 ) + 5 = - x

( - x / 4 ) - ( 1 / 2 ) + 5 = - x

Now, LCM of 2 and 1 is 2.

Therefore,

( - x / 4 ) + [ ( 10 - 1 ) / 2 ] = - x

( - x / 4 ) + ( 9 / 2 ) = - x

Adding x on both sides of the equation.

( - x / 4 ) + x + ( 9 / 2 ) = - x + x

Subtracting ( 9 / 2 ) from each side of the equation,

( - x / 4 ) + x + ( 9 / 2 ) - ( 9 / 2 ) = ( - 9 / 2)

( - x / 4 ) + x = ( - 9 / 2 )

LCM of 4 and 1 is 4

[ ( - x + 4x ) / 4 ] = ( - 9 / 2 )

( 3x / 4 ) = ( - 9 / 2 )

By cross multiplying,

2 × 3x = - 9 × 4

6x = - 36

Dividing each side of the equation by 6.

( 6x / 6 ) = ( - 36 / 6 )

x = - 6

Movie theater got 200 dollars and sold 47 tickets
How many tickets did movie a sell

Answers

Answer:

ticket for movie A = 35
ticket for movie B = 12

Step-by-step explanation:

Let A= is ticket  for movie A
Let A= is ticket  for movie B

We have A + B  = 47 (1)
4A + 5B = 200  (2)

From (1) multiply 5 in both side 5A + 5B = 47(5)= 235
                                                     4A + 5B =           200

So A = 35
   B= 47-35 = 12

Find an expression which represents the sum of (10x - 4y) and (4x -8y) in simplest terms.​

Answers

Answer:

14x - 12y

Step-by-step explanation:

Let's write the sum:

(10x - 4y) + (4x -8y)

Because we're only doing addition and subtractaction, we can drop the  parentheses that aren't preceded by a minus sign, they don't change the order.

10x - 4y + 4x - 8y

as long as we don't change the sign preceding each component, we can reorder as we wish

10x + 4x - 4y - 8y

(10x + 4x) - (4y + 8y)

note that because we added a parenthesis preceded by a - the sign inside changed.

We perform additions inside of the parentheses:

10x + 4x = 14x

4y + 8y = 12y

and we arrive at the final result:

14x - 12y

Q1. [tex](-\frac{3}{2},0)[/tex]

Q2. (-16, 0)

Step-by-step explanation:

The midpoint of a line segment is given by the formula:

[tex]\boxed{\text{Midpoint}=(\frac{x_1+x_2}{2} ,\frac{y_1+y_2}{2} )}[/tex]

In the formula, [tex](x_1,y_1)[/tex] is the first endpoint while [tex](x_2,y_2)[/tex] is the second endpoint of the line segment.

__________

Q1. Substitute the given endpoints into the formula:

Midpoint

[tex]=(\frac{-5+2}{2} ,\frac{5-5}{2} )[/tex]

[tex]=(\frac{-3}{2} ,\frac{0}{2} )[/tex]

[tex]= \bf{(-\frac{3}{2} ,0)}[/tex]

__________

Q2. Let the other endpoint be (x, y).

Substitute the given midpoint and one endpoint:

(-6, 4)=[tex](\frac{x+4}{2} ,\frac{y+8}{2} )[/tex]

Comparing the x-coordinate:

[tex]\frac{x+4}{2} =-6[/tex]

Multiply both sides by 2:

x +4= -12

Subtract 4 from both sides:
x= -12 -4

x= -16

Comparing the y-coordinate:

[tex]\frac{y+8}{2} =4[/tex]

Multiply both sides by 2:

y +8= 8

Subtract 8 on both sides:

y= 8 -8

y= 0

The coordinates of the other endpoint is thus (-16, 0).

Step-by-step explanation:

your own work, please ...

my own work is

1.

the midpoint between 2 points (x1, y1) and (x2, y2) is

((x1 + x2)/2, (y1 + y2)/2)

so, our midpoint is

((-5 + 2)/2, (5 + -5)/2) = (-3/2, 0/2) = (-3/2, 0)

2.

we have

((x1 + 4)/2, (y1 + 8)/2) = (-6, 4)

so,

(x1 + 4)/2 = -6

x1 + 4 = -12

x1 = -16

(y1 + 8)/2 = 4

y1 + 8 = 8

y1 = 0

so, the other endpoint is (-16, 0).

Rewrite the formula to solve for the positive value of r in terms of h and v.

Answers

Answer:

[tex]r=\sqrt{\dfrac{3V}{\pi h}}[/tex]

Step-by-step explanation:

The formula for the volume of a cone is given by :

[tex]V=\dfrac{1}{3}\pi r^2 h[/tex]

Where

r is radius of cone and h is its height

We need to solve the above formula for r.

Cross multiplying both sides of the given formula

[tex]3V=\pi r^ 2h[/tex]

Dividing both sides by πh.

[tex]\dfrac{3V}{\pi h}=\dfrac{\pi r^2 h}{\pi h}\\\\r^2=\dfrac{3V}{\pi h}\\\\r=\sqrt{\dfrac{3V}{\pi h}}[/tex]

So, the formula for r is [tex]\sqrt{\dfrac{3V}{\pi h}}[/tex]

What is absolute value and why is it always positive?

Answers

Answer:

Step-by-step explanation:

An absolute value is the distance a number is from 0 on the number line. So, regardless if it is a negative or a positive number, the distance from that number to 0 will always be positive. For example, -5 is 5 units away from 0, and 5 is also 5 units from zero. They have the same absolute value, even though one is negative and the other is positive.

Answer:

You can describe absolute value as a number's (Negative or positive) distance from zero.

Step-by-step explanation:

Say you have 4 and -4. 4's absolute value is four because it is four number units away from zero. -4 is a negative number but its absolute value would still be positive four because it is still four number units away from zero even though those number units are negative.
