<h2>Answer: A.</h2>

Step-by-step explanation:

Victoria's recipe:

170g of butter = 250 g of flour

1 g of butter = 250 ÷ 170 = 25/17 g of flour

Daughter's recipe:

340 g of butter = 400 g of flour

1 g of butter = 400 ÷ 340 = 20/17 of flour

Compare:

20/17 < 25/17

⇒ Daughter uses less flour in her cookies

⇒ the cookies are more dense

So therefor, the correct answer is A. They have too much butter :)

* Hopefully this helps:) Mark me the brainliest:)!!!!

Radda [10]

Answer:

$V(x) = 4x^3 - 24x^2+35x$

Step-by-step explanation:

Given

$V(x) = (7 - 2x)(5 - 2x)(x)$

Required

Expand the expression

$V(x) = (7 - 2x)(5 - 2x)x$

Expand bracket

$V(x) = (7 - 2x)(5 * x - 2x * x)$

$V(x) = (7 - 2x)(5x - 2x^2)$

Further expand bracket

$V(x) = 7(5x - 2x^2) - 2x(5x - 2x^2)$

$V(x) = 35x - 14x^2 - 10x^2 + 4x^3$

$V(x) = 35x - 24x^2 + 4x^3$

$V(x) = 4x^3 - 24x^2+35x$

Evaluate f(t)=-2t2+ 1 for f(-3).

podryga [215]

Answer:

Step-by-step explanation:

First, plug-in f(-3) into t in the function:

$f(-3)=-2(-3) +1$

Second, multiply -2 and -3 to get 6:

$f(-3)=-2(-3)+1$ ⇒ $f(-3)=6+1$

Third, add 6 and 1 to get your answer:

$f(-3)= 6+1$ ⇒ $f(-3)=7$

mr. huber bought a block of fudge that weighed 2/5 of a pound. he cut the fudge into 6 equal pieces. what was the weight of each

Marina86 [1]

Answer:

$\large \boxed{\frac{1}{15} \text{ lb}}$

Step-by-step explanation:

You are starting with ⅖ lb of fudge. Then you cut it into six pieces.

You want to evaluate ⅖ ÷ 6

1. Treat the integer as a fraction

$\dfrac{2}{5}\div{\dfrac{6}{1}}$

2. Invert the divisor and change divide to multiply

$\dfrac{2}{5}\times{\dfrac{1}{6}}$

3. Divide numerator and denominator by 2

$\dfrac{1}{5}\times{\dfrac{1}{3}}$

4. Multiply numerators and denominators

$\dfrac{1}{5}\times{\dfrac{1}{3}} = \mathbf{\dfrac{1}{15}}\\\\\text{Each piece of fudge weighs $\large \boxed{\mathbf{\frac{1}{15}} \textbf{ lb}}$}$

A study examines the relationship between educational preparation and scores on a cultural competency exam. Subjects included ar

Vikentia [17]

Answer:

b. Independent variable

Step-by-step explanation:

Understanding the definition of variables is necessary to grasp the notion of independent and dependent variables. The attributes or sorts of features of specific occurrences or things are specified as variables.

Independent variables are variables that are modified or altered by researchers and the consequences of these modifications are evaluated and compared.

The term dependent variable relates to a sort of variable that assesses how the independent variable(s) impact the test results.

From the given information:

Education level is the predictor since we understand that nurses' education levels are closely correlated with their cultural competence scores. By applying the concept of the logistic regression model and using education level as an independent variable(predictor), we can simply predict their cultural competency. Thus, cultural competency is measured by using the independent variable.
