Which best describes the structure of the expression (5 ⋅ 46.4) − (3.2 ⋅ 13.7)

2 answers:

8 0

You are subtracting the results in the parenthesis.

I would go with a difference.

Since 8 is being multiplied by 23.6 and -7.8, I would say product.

"A" is the best answer choice.

I hope this helps!

Answer:

Option (b) is correct.

The expression is equivalent, but the term is not completely factored.

Step-by-step explanation:

Given : a student factors to

We have to choose the correct statement about from the given options.

Given is factored to

Consider

Using algebraic identity,

comparing and b = 4, we have,

Thus, the factorization is equivalent but we can simplify it further also, as

Using algebraic identity,

Thus,

Can be written as

Can someone show how to solve this step by steps

horrorfan [7]

Answer:

$133.33

Step-by-step explanation:

When dealing with such a problem we can use the Rule of Three. This rule is basically used in order to find the missing value when dealing with a ratio. Like so...

12% of final price <======> $16

100% of final price <=====> x

Now we multiply the two available diagonal values together and divide by the last value in order to get the value of the variable, which in this case would be the original price in dollars

(100 * 16) / 12 = x

1600 / 12 = x

133.33 = x

Finally, we can see that the original price of the item was $133.33

What is the function g(x) created from f(x) = x^2 by moving the graph left 9 units, vertically stretching it by a factor of 4, a

MariettaO [177]

Given:

The parent function is $f(x)=x^2$

We need to determine the function g(x) created from the function f(x) by moving the graph left 9 units, vertically stretching it by a factor of 4, and shifting the graph up 5 units.

Shift left 9 units:

The rule to shift the graph c units to the left is given by

$y=f(x+c)$

where c is the positive real number.

Hence, to shift the graph 9 units to the left is given by

$f(x)=(x+9)^2$

Vertical stretch by a factor of 4:

The rule to stretch the graph vertically by a factor of c is given by

$y=cf(x)$

where $c>1$

Hence, to stretch the graph vertically by a factor of 4, we have;

$f(x)=4(x+9)^2$

Shifting 5 units up:

The rule to shift the graph c units upward is given by

$y=f(x)+c$

where c is the positive real number.

Hence, to shift the graph 5 units upward is given by

$f(x)=4(x+9)^2+5$

Therefore, the function $g(x)=4(x+9)^2+5$ is created from the graph $f(x)=x^2$ by moving the graph left 9 units, vertically stretching it by a factor of 4 and shifting up 5 units.

Hence, the graph g(x) is $g(x)=4(x+9)^2+5$

The outcome variable (usually Y) in a regression analysis is called the ________.

matrenka [14]

Answer:

Dependent variable

Step-by-step explanation:

The outcome variable (usually Y) in a regression analysis is called the ________.

c) dependent variable

If there are two variables and there is a linear correlation between them we try to find the regression line by using least squares method.

X the variable which is input or which is first found out is called independent variable.

The outcome variable is the dependent variable

Dummy variable is one which takes only values 0 or 1 depending on whether not present or present.
