Answer:

d = -4

Step-by-step explanation:

3d – 4 + d = 8d – (-12)

3d - 4 + d = 8d + 12

4d - 4 = 8d + 12

(4d - 4d) - 4 = (8d - 4d) + 12

-4 = 4d + 12

-4 - 12 = 4d (+ 12 - 12)

-16 = 4d

-16/4 = 4d/4

d = -4

Answer:

d= -4

Step-by-step explanation:

3d- 4 +d = 8d + 12

4d - 4 = 8d + 12

4d = 8d + 16

-4d = 16

d= -4

Check

-12 - 4 - 4 = -32 + 12

-20 = -20

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:

The mean is 70.8.

Step-by-step explanation:

Finding the arithmetic mean, or average, can be found by adding up all the numbers divided by the total count of those numbers.

So, we have :: 60, 67, 71, 76, 80.

These numbers added together = 354.

There are 5 numbers listed.

354 / 5 = 70.8.

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).

Answer:

2^3 .3^2

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

Then

72 = 2 × 2 × 2 × 3 × 3 = 2³ × 3²

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!

The 10 hypothetical numbers which meets the conditions given on the question may include :

1, 2, 3, 5, 6, 6, 7, 10, 10, 12

The five number summary include the maximum, minimum, lower quartile, Median and upper quartile of a distribution.

The five number summary of the hypothetical data are:

Median: 6

Minimum: 1

Maximum: 12

Lower quartile: 2.75

Upper quartile: 10

Comparing the 5 - number summary of the hypothetical data with that of the given boxplot.

From the given  boxplot shown :

Minimum value = 1

Maximum value = 12

Median = 6

LOWER QUARTILE, Q1 = 4

UPPER QUARTILE, Q3 = 8

IQR = (Q3 - Q1) = 8 - 4 = 4

THE 10 made up numbers :

1, 2, 3, 5, 6, 6, 7, 10, 10, 12

The five number summary for the made up data :

Median = 1/2(n+1)th term = 5.5th term = (6+6)/2 = 6

Minimum: 1

Maximum: 12

First quartile = 1/4(n+1)th = 2.75th term = (2+3)/2 = 2.5

Third quartile: 3/4(n+1)th term = 8.25 = (10+10)/2 = 10

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.

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.
