Answer:

Error term

Step-by-step explanation:

Given :

In a regression analysis, the actual values of Y may be found above or below the regression line. These deviations are called the _____. slope error term variance standard error of the mean standard deviation

To find :

Fill in the blanks.

Now, In a regression analysis, the actual values of Y may be found above or below the regression line. These deviations are called the Error term.

Because we use the error term in the regression analysis difference between the actual value of \(Y\) and the approximate value of \(Y\) which is above of actual value or below of actual value.

 As \(Y\)is an actual value and \(Y_0\) is an approximate value then,

\(|Y-Y_0|\) is an error.

It is a vertical distance between the actual value and the approximate value  of \(Y\).

So, the error term is always positive.

The function is solved for the given intervals and the values are noted

Given data ,

Let the function be represented as f ( x )

10 (8-x)(8+x)

Step-by-step explanation:

640-10x^2

Factor out 10

10 (64 - x^2)

Notice that inside the parentheses is the difference of squares

10 ( 8^2 - x^2)   and a^2 - b^2 = (a-b) (a+b)

10 (8-x)(8+x)

Answer:

10(8 - x)(8 + x)

Step-by-step explanation:

Given

640 - 10x^2

Solution

Take out 10 on each side of the minus sign

10(64 - x^2)

The expression in the brackets is a difference of squares which factors as

a^2 - b^2 = (a + b)(a - b)

Factor the expression inside the brackets as a difference of squares.

64 = 8*8

x^2 = x*x

10(8 - x)(8 + x)

The area of the circle with the given radius is 201.088 square units.

The area of a circle is the space occupied by the circle in a two-dimensional plane. Alternatively, the space occupied within the boundary/circumference of a circle is called the area of the circle. The formula for the area of a circle is A = πr², where r is the radius of the circle.

Given that, the radius of a circle is 8 units.

Here, area of a circle

= 3.142×8²

= 3.142×64

= 201.088 square units

Therefore, the area of the circle is 201.088 square units.

Check the pictures attached for the answers.

Answer:

\((a)\ Area = 28.12cm^2\)

\((b)\ Volume = 1437.33cm^3\)

Step-by-step explanation:

Solving (a): The parallelogram

\(h = 7.6\) --- height

\(b = 3.7\) --- base

The area is calculated usng:

\(Area = base * Height\)

\(Area = 3.7 * 7.6\)

\(Area = 28.12cm^2\)

Solving (b): The sphere

\(d = 14cm\)

Required

The volume

First, calculate the radius

\(r = d/2\)

\(r = 14cm/2 = 7c,\)

The volume is calculated using:

\(Volume = \frac{4}{3} \pi r^3\)

This gives:

\(Volume = \frac{4}{3} * \frac{22}{7} * 7^3\)

\(Volume = \frac{4}{3} * 22 * 7^2\)

\(Volume = \frac{4}{3} * 1078\)

\(Volume = \frac{4*1078}{3}\)

\(Volume = \frac{4312}{3}\)

\(Volume = 1437.33\)

The Linear equation that represents the above situation is given by

x + 3x + 15 = 63

A linear Equation is a Mathematical expression that is used to calculate an unknown number of values or any unknown quantity. Here we use variables to represent the unknown numbers.    

Here given that

Luke and Cade have started running

Luke runs 15 more miles than thrice of that of number of miles Cade runs

Since we don't know the number of miles run by Cade

Let us assume that Cade runs x miles

=> Number of miles run by Cade = x miles

From the given data,

The number of miles run by Luke will be = 3x + 15

=> Number of miles run by Luke and Cade = x + 3x + 15

Given that the total mile run by Luke and Cade =  63 miles  

=> x + 3x + 15 = 63

Step-by-step explanation:

P(event)= favorable outcomes / total outcomes

0.84 * 100 = 84

100 - 84 = 16

84 favorable outcomes

16 unfavorable outcomes

100 total outcomes

Therefore there is a 84% chance of it happening.

Therefore there is a 16% chance of it not happening.

P(event) = 84/100

8.4 out of 10

Describe it how ever you want. 8.4 out of 10 is a pretty good bet to me. I would put my money on it. There isn't a lot of context to the question. But, I hope this helps!

It means 840 times out of 1000 times, an event is likely to happen or in other words, there is an 84% chance of happening an event.

Probability is to measure the occurrence of an event.

It is given that

probability of an event = 84% or 0.84

This means, P(E) = 0.84

Number of favorable outcomes/ Total outcomes =84

Let us say Total outcomes are 1000

So favorable outcomes = 1000*0.84

Favorable outcomes = 840

Using a trigonometric identity, it is found that the values of the sine and the tangent of the angle are given by:

The identity that relates the sine squared and the cosine squared of the angle, as follows:

\(\sin^{2}{\theta} + \cos^{2}{\theta} = 1\)

In this problem, we have that the cosine is given by:

\(\cos{\theta} = -\frac{\sqrt{3}}{2}\)

Hence:

\(\sin^{2}{\theta} + \cos^{2}{\theta} = 1\)

\(\sin^{2}{\theta} = 1 - \cos^{2}{\theta}\)

\(\sin^{2}{\theta} = 1 - \left(-\frac{\sqrt{3}}{2}\right)^2\)

\(\sin^{2}{\theta} = 1 - \frac{3}{4}\)

\(\sin^{2}{\theta} = \frac{1}{4}\)

\(\sin{\theta} = pm \sqrt{\frac{1}{4}}\)

Since the angle is in the third quadrant(between pi and 1.5pi), the sine is negative, hence:

\(\sin{\theta} = -\frac{1}{2}\)

The tangent is given by the sine divided by the cosine, hence:

\(\tan{\theta} = \frac{\sin{\theta}}{\cos{\theta}} = \frac{-\frac{1}{2}}{-\frac{\sqrt{3}}{2}} = \frac{1}{\sqrt{3}} \times \frac{\sqrt{3}}{\sqrt{3}} = \frac{\sqrt{3}}{3}\)

The acceleration of the car is 8 m/s^2.

The figure shown in the question is the distance-time graph of a muscle car accelerating from a standstill. The table lists the coordinates of points on the graph.The following observations can be made from the graph and the table: The car is at rest at time t=0 and at distance x=0. It then starts accelerating, and its speed increases uniformly with time. The slope of the distance-time graph is the velocity of the car.

Since the velocity is increasing uniformly, the slope of the graph is a straight line with a positive slope. The area under the graph between two points gives the displacement of the car during that time interval. The displacement can be calculated as the product of the average velocity and the time interval. Using the coordinates in the table, we can calculate the average velocities for each time interval and the displacement during that interval.

(a) The average velocity of the car between t=0 and t=2 is equal to the slope of the graph between the two points (0,0) and (2,32). This can be calculated as the difference in distance divided by the difference in time:Average velocity = (32 - 0) / (2 - 0) = 16 m/sThe displacement during this time interval is given by the area under the graph between the two points:Displacement = (1/2) x 32 x 2 = 32 m

(b) The acceleration of the car is given by the slope of the velocity-time graph. Since the velocity is increasing uniformly with time, the velocity-time graph is also a straight line with a positive slope. The slope of the velocity-time graph is equal to the acceleration. We can calculate the slope of the velocity-time graph between two points using the coordinates in the table. For example, the slope between t=0 and t=2 is given by the difference in velocity divided by the difference in time:Slope = (16 - 0) / (2 - 0) = 8 m/s^2

Q) 4 - 16 = ?

→ 4 - 16

→ [ -12 ]

The answer is -12.

Answer:

f = -15

Step-by-step explanation:

Use algebra to solve!

f/3 + 22 = 17

f/3 = 17 - 22 (bring 22 to the other side, this changes the sign from plus to minus)

f/3 = -5 {because 17-22 = (-5)}

f = (-5) (3) {to eliminate 3 from the denominator of f, you do the opposite of division which is multiplication, so -5 times 3}

therefore, f = -5

You can also check this answer by putting it back into the original equation, -15/3 is -5 and then -5 + 22 = 17.
