The sum of 7 plus 5 is given by:
 7 + 5 = 12

 The following fact has the same result:
 Suppose Carlos trains at the gym for 10 months, if Carlos wants to train for 2 more months. How many months will Carlos train at the gym?
 
We have then that the result is given by:
 10 + 2 = 12

 Therefore, Carlos will train 12 months in the gym.
 The result is equal to the given expression above.

Answer and explanation:

To find : Write a fact with the same sum as 7+5 ?

Solution :

A fact family is defined as a group of math facts or equation created using the same set of numbers.

The fact family shows the relationships between the three numbers involved.

We have given the same sum as 7+5,

i.e. 7+5=12

Now forming different relation between 7,5 and 12 using addition and subtraction were the fact,

7+5=12

5+7=12

12-5=7

12-7=5

1. Drake is Bradley's sister.
2. Cursen is Atley's brother
3. Norma and Drake are not related

Drake is a girl (1), but she is not related to Norma(3), So she is Marlene.
1) MARLENE DRAKE

Drake and Bradley are related; Norma is not related to them(3). Norma can either be Atley or Cursen. But, Cursen is Male. So, Norma is NORMA ATLEY

Remaining family names are Bradley and Cursen. Kermit is not a Bradley, so he is KERMIT CURSEN. That leaves LEONARD BRADLEY.

Kiran has 27 nickels and quarters in his pocket, worth a total of $2.75.
Montano1993 [528]

The system of equations is

n + d = 27

n + 5d = 55

Step-by-step explanation:

The given is:

  • Kiran has 27 nickels and quarters in his pocket
  • They worth a total of $2.75
  • We need to write a system of equations to represent the relationships between the number  of nickels n, the number of quarters d, and the dollar amount in this situation

∵ The number of nickles is n

∵ The number of quarters is d

∵ There are 27 nickles and quarters

∴ n + d = 27 ⇒ (1)

∵ 1 nickel = 5 cents

∵ 1 quarter = 25 cents

- Multiply n by 5 and d by 25 to find their value

∴ They worth = 5n + 25d

∵ They worth a total of $2.75

- Chang the dollar to cent

∵ 1 dollar = 100 cents

∴ $2.75 = 2.75 × 100 = 275 cents

- Equate their value by 275

∴ 5n + 25d = 275

- Simplify it by divide each term by 5

∴ n + 5d = 55 ⇒ (2)

The system of equations is

n + d = 27

n + 5d = 55

Given a grid with 15 sections, determine how many sections in the grid need to be shaded so the probability of a point chosen at
Nikitich [7]

Answer:

12

Step-by-step explanation:

0.8 is equal to 80%

you need to figure out 80% of 15

100% = 15

10% = 1.5

(x8)

80% = 12

you would need to shade 12 out of 15 boxes which gives 0.8 chance of picking a shaded one

Jeff want to build a model to predict the relationship between graduate GPA and first job salary. He collected data below. Jeff
umka21 [38]

Answer:

Approximate intercept is  4,515.33  

Step-by-step explanation:

The intercept of the GPA grades and the first job salary can be determined by using the intercept function in excel spreadsheet.

In order to ascertain the intercept,we apply the intercept formula:

=intercept(known values of y,known values of x)

known values of y are the dependent variables.The first annual salary in this scenario is dependent upon the GPA of the graduate in question

Known values of x are the independent variables upon which the dependent ones rely for their values i.e the GPA itself

As found in the attached,the intercept is  4,515.33
