Substitute the known values in the above equation

So, we have

Rate of making nails = 4th pounds/0.5 hour

Evaluate

Rate of making nails = 8th pounds per hour

We are given a trapezoid and we are asked to determine one of its angles. To do that we need to have into account that the following angles are equal:

Also, the sum of two different angles must be equal to 180, therefore, we have the following relationship:

Replacing the value of angle W:

Subtracting 112 to both sides:

Therefore, the measure of angle Z is 68.

1. Common ratio of the G.P is 50

2. First term of the G.P is -100

3. Sum of the 8th term is 250.

Given,

In a Geometric progression,

7th term is 16 times the 3rd term

Sum of 2nd and 6th term is 102

Common ratio is positive.

Now,

Take a as first term.

r as common ratio

Then,

2nd term = a + r

6th term = a + 5r

So,

a + r + a + 5r = 102

Then,

2a + 6r = 102

2a = 102 - 6r

a = (102 - 6r) / 2

Now,

1. Common ratio:

Consider any term,

Here, 3rd term = a + 2r

Substitute a here.

a + 2r =  (102 - 6r) / 2 + 2r

102 - 6r + 4r = 2

102 - 2 = 6r - 4r

100 = 2r

r = 100/2 = 50

That is,

The common ratio of the G.P is 50.

2. First term:

Consider,

7th term is 16 times the 3rd term

That is,

3rd term = a + 2r

7th term = 16(a + 2r)

r = 50

Then,

a + 50 × 2 = 16(a + 50 × 2)

a + 100 = 16(a + 100)

a + 100 = 16a + 1600

100 - 1600 = 16a - a

15a = -1500

a = -1500/15

a = -100

Therefore,

The first term of the G.P is -100

3. Sum of the 8th term.

8th term = a + 7r = -100 + 7 × 50 = -100 + 350 = 250

That is,

The sum of the 8th term is 250.

The equivalent expressions to (9 7/8 + 2 4/5) - 1/2 are given as follows:

a) 9 7/8 + (2 4/5) - 1/2.

b) 9 7/8 + 2 4/5 + (-1/2).

Equivalent expressions are expressions that have the same result.

In this problem, the expression a is equivalent to the given expression, as the only difference is the order of the operations being applied, as the subtraction of 2 4/5 and -1/2 is applied before the addition of 9 7/8 + 2 4/5.

Expression b is also equivalent to the given expression, as an addition with the negative number in the fraction is made. However, the addition sign means that the sign inside the parenthesis is kept, which is negative, hence no change is made to the expression.

The remaining expressions involve changes to the signals of each term, hence they are not equivalent to the presented expressions.

Step-by-step explanation:

The 95% confidence interval will be more extensive than the 90% confidence interval

In measurements, the probability that a population boundary will fall between a bunch of values for a specific level of the time is alluded to as a certainty stretch. Investigators every now and again utilize certainty goes that incorporate 95% or the vast majority of expected perceptions. Thus, it could be presumed that there is a 95% probability that the genuine worth falls inside that reach assuming that a point gauge of 10.00 with a 95% certainty time frame - 10.50 is determined utilizing a factual model.

The degree of conviction or vulnerability in a testing cycle is estimated by certainty spans.

Also, they are utilized in relapse examination and speculation testing.

To decide measurable importance, analysts often join certainty spans with p-values.

95% or almost 100% certainty levels are most often utilized in their development.

The most appropriate choice for equation of line in slope intercept form will be given by-

Rate of change is 8 and rate of change represents slope of the line

What is equation of line in slope intercept form?

Equation of line in slope intercept form is written as y = mx +c

m is the slope of the line and c is the y intercept of the line.

The distance between the origin and the point where the line cuts the x axis is the x intercept

The distance between the origin and the point where the line cuts the y axis is the y intercept

Here,

Let the number of classes be x

Total cost of classes = y

Let the equation of line be y = mx + c

Three classes cost $36

Putting x = 3, y = 36

36 = 3x + c .............. (1)

Seven classes cost $68

Putting x = 7, y = 68

68 = 7x + c ............... (2)

Subtracting equation (2) from (1),

4x = 32

[tex]x = \frac{32}{4}[/tex]

x = 8

Putting the value of x in (1)

[tex]3 \times 8 + c = 36\\24 + c = 36\\c = 36 - 24\\c = 12[/tex]

Equation of line is y = 8x + 12

Now coefficient of x in y = mx  + c is the slope of the line and that is the rate of change

so, rate of change is 8 and rate of change represents slope of the line.

Answer:

Step-by-step explanation:

Given school costs of $36 for 3 classes and $68 for 7 classes, you want to know the rate of change and its meaning.

The "rate of change" in this context is the change in cost for one additional class. It can be found by ...

  rate of change = (change in classes) / (change in cost)

  rate of change = ($68 -$36)/(7 classes -3 classes) = $32/(4 classes)

  rate of change = $8/class

This "rate of change" is the additional cost for the addition of one class. It is the cost per class.

A function with the formula f(x) = ax + b, where a and b are real values, is referred to as a linear function.

The rate of change will be 3/4.

A function with the formula f(x) = ax + b, where a and b are real values, is referred to as a linear function. Here, a stands for the line's gradient, and b for the y-axis intercept (which is sometimes called the vertical intercept).

The rate of change of y with respect to x, can be calculated utilizing any two of the pairs of values of the table, say, (3, -5) and (7, -2).

Rate of change [tex]$=\frac{y_2-y_1}{x_2-x_1}$[/tex]

Let, (3, -5) = (x1, y1) and (7, -2) = (x1, y1).

The amount of money Landon will make in 1 hour is $12 and he needs to work for 13 hours to make $156.

The amount of money he will make in 1 hour can be calculated by using division.

It can be determined by dividing the total amount earned by him by the total number of hours he worked yesterday. Therefore;

money earned in 1 hour = total amount earned ÷ total number of hours

money earned in 1 hour = 48 ÷ 4

money earned in 1 hour = $12

Now we can calculate the number of hours he needs to work at the movie theater to make $156 by dividing the desired amount by the amount earned in one hour. Therefore;

number of hours required = 156 / 12

number of hours required = 13

The elevation of the hole after placing the bush in the hole is 93 feet

This is a problem from the unitary method. We can easily solve this problem by following a few steps.

Joel digs a hole at a rate of 35 feet every 10 minutes. So, we have to calculate the rate at 1 min.

Joel digs a hole at a rate of 35 feet every 10 minutes

Joel digs a hole at a rate of 35/10 feet every 1 minute

[ Work done for unit minute = Total work done / total time period ]

Now we have to calculate the total work done for 30 minutes.

For a unit minute work done is 35/10, then for 30 minutes the total work done is, (35/10 × 30 ) feet = 105 feet.

Joel places a bush in the hole that fills exactly 12 feet of the hole.
