Answer:

8. thousands, 5,000

9. millions 6,000,000

Step-by-step explanation:

Answer:

8: thousands place, 5,000

9: millions place, 6 million

Step-by-step explanation:

Place value is quite confusing at first, but it gets to be much easier. Basically, every time you add a place on a number, you are increasing its place value! Lets use number 9 for example. The one in this number is in the ones place. You know this because it is the last digit. The 4, is the tens place, since it is directly to the left of the ones place. You are increasing the place value to the left. The order of place value is:

Ones

Tens

Hundreds

Thousands

Ten thousands

Hundred thousands

Millions

Ten Millions

Hundred Millions

Billions

and so on. I hope this was helpful!

Answer:

[tex] \frac{5}{12} \: \: \: \frac{5}{8} \: \: \: \frac{5}{7} \: \: \: \frac{5}{6} [/tex]

Step-by-step explanation:

The trick to this is looking at the denominator. If the numerators are the same for all fractions you are comparing then things are going to be a bit easier for comparing them. The one that has the biggest denominator is small and the one with the smaller denominator is a bigger fraction.

hope this makes sense

Answer:

They are similar.

Step-by-step explanation:

123 + 36 + x = 180

159 + x = 180

(159 - 159) + x = 180 - 159

x = 21

36 + 21 + x = 180

57 + x = 180

(57 - 57) + x = 180 - 57

x = 123

CDE = 123 + 36 + 21

ABC = 123 + 36 + 21

Answer:

0.4

Step-by-step explanation:

0.35 is hundredth, and since you always round 5 up, it makes 0.4

Answer:

0.4

Step-by-step explanation:

To figure out the answer, first we need to know how to round. Find the tenths place. That's the first 3 you come upon. Look at the number beside it. It is a five which means you would round up (this is because of the 5 or more raise the floor, four or less let it rest rule) The 3 would then turn into a 4.

The correct option is (a) i.e. Regression equations are usually used to predict values of unavailable data. If the data do not closely model a particular type of function, then that type of function is not appropriate to use in statistical regression. The more closely data fit a model, the more accurate predicted values will be.

What is Regression analysis?

A collection of statistical techniques known as regression analysis is used to estimate the associations between a dependent variable and one or more independent variables. It can be used to simulate the long-term link between variables and gauge how strongly the relationships between them are related.

Although there are non-linear regression techniques for more complex data and analysis, simple linear regression and multiple linear regression are the two fundamental types of regression. While multiple linear regression employs two or more independent factors to predict the outcome, simple linear regression just uses one independent variable to explain or predict the outcome of the dependent variable Y. (while holding all others constant).

Professionals in other industries, including banking and investment, might benefit from regression. Regression can also aid in predicting sales for a business based on external factors like the weather, past sales, GDP growth, and other variables. A popular regression model in finance for valuing assets and calculating capital expenses is the capital asset pricing model (CAPM).

Step-by-step explanation:

Hi there!

Given;

f(x) = 5x-1

Now; Simply keep the value of x in the given function.

f(1) = 5*1-11

= -6

Again;

f(3) = 5*3-11

= 15-11

= 4

Therefore, f(1) = -6 and f(3) = 4.

Step-by-step explanation:

if 2×2×2 = 8

and 3×3=9 then 8×9=72

Answer:

2³ × 3²

Step-by-step explanation:

Repeatedly divide by 2 until finish, then divide by 3

72 ÷ 2 = 36

36 ÷ 2 = 18

18 ÷ 2 = 9 , then

9 ÷ 3 = 3

3 ÷ 3 = 1 ← finish when 1 is reached

Answer:

14

Step-by-step explanation:

If the negative was outside of the lines, then the answer would be -14, but that is not the value. It is 14.

Answer:

D

Step-by-step explanation:

-14 is in Absolute Value signs. This means that if a number is in the absolute value signs, It's always positive. So that leaves us with C, D, or E. Absolute value signs also mean they are the same number as if it was negative, so that tells us that the answer is D!

Step-by-step explanation:

Let's find the distance between your two points.

(−5,5);(−2,3)

(x1,y1)=(−5,5)

(x2,y2)=(−2,3)

Use the distance formula:

D=√(x2−x1[tex])^{2}[/tex]+(y2−y1[tex])^{2}[/tex]

=√(−2−−5[tex])^{2}[/tex]+(3−5[tex])^{2}[/tex]

=√(3[tex])^{2}[/tex]+(−2[tex])^{2}[/tex]

=√9+4

=√13

D=√13(Decimal: 3.605551)

Answer:

The actual change in the car's value is $[tex]1700[/tex] and the relative change is [tex]7.20[/tex]%.

Step-by-step explanation:

It is given that the value of a car is dropped from $[tex]23600[/tex] to $[tex]21900[/tex].

So, the change in the value is the drop in the value of car, which is, [tex]23600-21900=1700[/tex].

So, the actual change in this car's value is $[tex]1700[/tex].

The relative change can be given by the expression,

[tex]\dfrac{\:\rm{Actual Change}}{\:\rm{Original Value}}\times100[/tex]

Substituting values, the relative change can be given by,

[tex]\begin{aligned}\dfrac{1700}{23600} \times 100&=\dfrac{1700}{236}\\&=7.20\end{aligned}[/tex]
