The amount of dry ingredients used in the cake recipe is approximately 7 cups.

To find the total amount of dry ingredients used in the cake recipe, we need to add up the amounts of flour, sugar, and cocoa.

3 ½ cups of flour is equal to 3 cups plus 0.5 cups, or 3 cups and 8 ounces.

2 ⅔ cups of sugar is equal to 2 cups plus 0.67 cups, or 2 cups and 10.72 ounces.

1 ¾ cups of cocoa is equal to 1 cup plus 0.75 cups, or 1 cup and 12 ounces.

Adding these amounts together, we get:

3 cups and 8 ounces + 2 cups and 10.72 ounces + 1 cup and 12 ounces = 6 cups and 14.72 ounces

To the nearest cup, this is equal to 7 cups.

Therefore, the amount of dry ingredients used in the cake recipe is approximately 7 cups.

Answer: the answer is c (the third answer ) ‼️

Step-by-step explanation:

The data in the given residual plot shows that model C has the best fit.

A straight line that minimizes the gap between it and some data is called a line of best fit. In a scatter plot containing various data points, a relationship is expressed using the line of best fit.

Given:

The residual plot of the values in the graph,

The points in the first graph are very far from the x-axis and y-axis so, it is not the best fit,

The points in the second graph are very far from the x-axis and y-axis, and they are symmetric to the y-axis but not the best fit.

Most of the points are close to the x-axis, so it is the best fit,

Thus, the third graph is the best line of fit.

Answer:

no solutions

Step-by-step explanation:

the equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

equation of blue line is y = x + 2 , in slope- intercept form

with slope m = 1

equation of red line is y = x - 3 , in slope- intercept form

with slope m = 1

• Parallel lines have equal slopes

then the blue and red lines are parallel.

the solution to the system is at the point of intersection of the 2 lines

since the lines are parallel then they do not intersect each other.

thus the system shown has no solution.

Width is 3 feet

Length is 15 feet

Step-by-step explanation:

Formula for perimeter of a rectangle;

Perimeter = 2(length + width)

- let the width be w

- Length = (3w + 6) feet

Therefore;

\({ \rm{perimeter = 2 \{(3w + 6) + w \}}} \\ { \rm{perimeter = 2 \{(3w + w) + 6 \}}} \\ { \rm{perimeter = 2(4w + 6)}} \: \: \: \: \: \: \: \: \: \: \: \: \: \)

But perimeter is 36 feet

\({ \rm{36 = 2(4w + 6)}} \\ \\ { \rm{ \frac{36}{2} = \frac{2(4w + 6)}{2} }} \\ \\ { \rm{18 = 4w + 6}} \: \: \: \: \: \: \: \: \: \\ { \rm{4w + 6 = 18}} \: \: \: \: \: \: \: \: \\ { \rm{4w = 18 - 6}} \: \: \: \: \: \: \: \: \\ { \rm{4w = 12}} \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \\ { \rm{w = 3}} \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \)

Answer:

\(n=126\)

Step-by-step explanation:

Using the formula for the sum of the angles of an \(n\)-sided polygon, the sum of the angles is \(180(n-2)\) degrees.

An exterior angle is supplementary to the corresponding interior angle. Using the given angle measures, the sum of the angles is \(2(180-50)+127+135+173n=522+173n\) degrees.

Equating these two results,

\(180(n-2)=522+173n \\ \\ 180n-360=522+173n \\ \\ 7n-360=362 \\ \\ 7n=882 \\ \\ n=126\)

Answer:

n=126

Step-by-step explanation:

180(n−2)=522+173n

180n−360=522+173n

7n−360=362

7n=882

n=126

The second differences for the relation is -2 which is option A.

To find the second differences, we need to calculate the difference between consecutive differences of the 'y' values in the given relation.

First, let's calculate the first differences:

-9 - (-4) = -5

-4 - (-1) = -3

-1 - 0 = -1

0 - (-1) = 1

-1 - (-4) = 3

-4 - (-9) = 5

Now, let's calculate the second differences:

-5 - (-3) = -2

-3 - (-1) = -2

-1 - 1 = -2

1 - 3 = -2

3 - 5 = -2

The second differences for the given relation are all -2.

Step-by-step explanation:

The bisection method is a root-finding algorithm that repeatedly bisects an interval and then selects a subinterval in which a root must lie for further processing. To apply the bisection method to the equation x^3 - x - 9 = 0, you need to find two initial values a and b such that f(a) and f(b) have opposite signs. This means that there is at least one root of the equation in the interval [a, b].

Let’s take a = 2 and b = 3 as our initial interval. We can see that f(2) = 2^3 - 2 - 9 = -1 and f(3) = 3^3 - 3 - 9 = 18, so f(a) and f(b) have opposite signs.

Now we can apply the bisection method as follows:

Calculate the midpoint c = (a + b)/2 = (2 + 3)/2 = 2.5.

Evaluate f© = 2.5^3 - 2.5 - 9 ≈ 5.625.

Since f© > 0 and f(a) < 0, there must be a root in the interval [a, c]. So we set b = c and repeat the process.

Calculate the new midpoint c = (a + b)/2 = (2 + 2.5)/2 = 2.25.

Evaluate f© ≈ 1.765625.

Since f© > 0 and f(a) < 0, there must be a root in the interval [a, c]. So we set b = c and repeat the process.

We can continue this process until we reach the desired level of accuracy.

Answer:

The constant of proportionality in the equation 2y = 2x is 1.

Note that this equation is actually the same as y = x, which is a linear equation with a slope of 1 and a y-intercept of 0. In this case, the coefficient of x (which is 2) is not the constant of proportionality because it does not represent a proportional relationship between x and y. Instead, the constant of proportionality is the ratio of the change in y to the change in x, which is 1.

Answer:

Amount of change: 4,000 - 3,600 = 400

Percent of change: 400/4,000 = 1/10 = 10%

Answer:

$200 is not part of the confidence interval, which means that this is not a reasonable conclusion, at the 100 - 95 = 5% level of significance.

Step-by-step explanation:

95% confidence interval: $72 to $198.

This means that we are 95% sure that the true mean spending is between $72 and $198.

From this confidence interval the assistant concluded that people spend an average of $200 a month on entertainment. Is this a reasonable conclusion and why?

$200 is not part of the confidence interval, which means that this is not a reasonable conclusion, at the 100 - 95 = 5% level of significance.

Answer:

To find 29% of 150, we can first express 29% as a decimal by dividing 29 by 100. 29% is the same as 0.29.

Then, we multiply 0.29 by 150 to find the answer:

0.29 * 150 = 43.5

So, 29% of 150 is equal to 43.5.

Here's the work:

29% * 150 = 0.29 * 150 = 43.5

\(\huge\text{Hey there!}\)

\(\mathsf{29\%\ of \ 150}\)

\(\mathsf{= \dfrac{29(150)}{100(1)}}\)

\(\mathsf{= 43 \dfrac{1}{2}}\)
