Answer:
495/224
Step-by-step explanation:
15/32⋅36/28⋅44/12
= (15/32(9/7))(44/12) [simplify 36/28]
=135/224 (44/12) [multiply]
=135/224 (11/3) [simplify 44/12]

jim invested his savings in two investment funds. the amount he invested in fund A was $3000 less than the amount he invested in fund B. Fund A returned a 8% profit and Fund B returned a 7% profit. How much did he invest in Fund B, if the total profit from the two funds together was $960?
Answer:
$8000
Step-by-step explanation:
Let it be that investment in A is x dollars, then Jim invested in B x+3000.
x/100*8=0.08x- the profit from A, (x+3000)/100*7= 0.07x+210
0.08x+0.07x+210=960
0.15x=750
x=750/0.15= 5000
5000+3000=8000dollars- investment in B
The required amount invested in Fund A is $5000, and in Fund B is $8000.
What are simultaneous linear equations?Simultaneous linear equations are two- or three-variable linear equations that can be solved together to arrive at a common solution.
Here,
Let the amount invested in fund A be x, and the amount invested in fund b be y.
x = y - 3000 - - - - - - - - - - -(1)
0.08x + 0.07y = 960 - - - - - - - - (2)
From the equation, 1
[y - 3000]0.08 + 0.07y = 960
y = $8000
Now,
x = 8000 - 3000
x = 5000
Thus, the required amount invested in Fund A is $5000, and in Fund B is $8000.

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 _______________ predicted values will be.
a.

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).

Shelly has 7/8 cup of lemonade. She pours 1/4 cup of lemonade in each glass. How many glasses can Shelly fill?
=============================================================
Explanation:
We can think of a similar problem involving [tex]8 \div 4[/tex] which could answer the question "if she has 8 cups and pours 4 cups per glass, then how many glasses can she fill?" (that answer being 2 glasses).
Then we replace the 8 with 7/8, and we also replace the 4 with 1/4. It's the same idea but now things have gotten a bit more complicated since we're dividing two fractions.

please show work 3d – 4 + d = 8d – (-12)
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

Solve d=a+c/ac for a
Answer:
a=d(ac)-c
Step-by-step explanation:
Yes (multiply ac both sides subtract C both sides gets a alone)

multiply either sides by ac :
[tex](d \times ac) = ( \frac{a + c}{ac} ) \times ac \\ \\ dac = a + c[/tex]
collect a - terms together, by subtracting a from both sides:

Answer:
(a) y = 5
Step-by-step explanation:
The equation of a horizontal line can be written as ...
y = constant
In order to make that line pass through a given point, the constant must match the y-coordinate of the point. Here, that is 5.
y = 5
Write the equation x² + 6x + y² – 8y = 19 in standard form.
Question 17 options:
1)
(x – 3)²+ (y – 4)² = √44
2)
(x + 3)² + (y + 4)² = 44
3)
(x + 3)² + (y – 4)²= 44
4)
(x + 3)² + (y – 4)² =√44
Answer:
Formula used :
x²+2xy+y² = (x+y)² x²-2xy+y² = (x-y)²[tex] →{x}^{2} + 6x + {y}^{2} - 8y = 19 \\ ({x}^{2} + 2.3.x + {3}^{2} ) +({y}^{2} - 2.4.y + {4}^{2} ) = 19 + {3}^{2} + {4}^{2} \\ {(x + 3)}^{2} + {(y - 4)}^{2} = 19 + 9 + 16 \\ \boxed{ {(x + 3)}^{2} + {(y - 4)}^{2} = 44}✓[/tex]
