Seven friends share the cost of a gift. Each friend pays $4.45. The gift costs $37.50. Can the friends buy the gift? Use estimation to justify your answer.

A. Yes; round 7 to 10, $4.45 to $4, and $37.50 to $38.
10 × $4 = $40, and $40 > $38.
B. Yes; round $4.45 to $5 and $37.50 to $35.
7 × $5 = $35, and $35 = $35.
C. No; round $4.45 to $5 and $37.50 to $40.
7 × $5 = $35, and $35 < $40.
D. No; round $4.45 to $4 and $37.50 to $38.
7 × $4 = $28, and $28 < $38.

Answer:

if he uses 1/2 for 2/3, then you can divide 2/3 and 1.2 by 2 to get the remaining soap needed to complete the wash

so to clean the last 1/3 of the car, he`ll use 1/4 of the remaining soap

the entire car needs 3/4 of a bottle of soap

2x/2 = -4/2

x = -2

Q) [35 - (8 + 2) × 3] = ?

→ 35 - {(8 + 2) × 3}

→ 35 - {10 × 3}

→ 35 - 30

→ 5 is the correct answer.

Answer:

D=√13(Decimal: 3.605551)

3.6

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)

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.

Hope it helps!

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
