This graph shows how many cookies Julia makes over 9 days.

a) How many total cookies will Julia have on
day 7?

b) Estimate the output when the input is 2.

The equation for the plane that passes through the point (3, 6, −7) and is perpendicular to the line v = (0, −6, 5) t(1, −2, 3) is given by: Ax + By + Cz + D = 0, where A, B and C are the components of the normal vector to the plane and (x, y, z) are the coordinates of a point on the plane and D is the constant.

To calculate A, B, C and D we need to take the dot product of the normal vector and the position vector.  Since the line is perpendicular to the plane, any vector parallel to the line can be a normal vector to the plane. Hence, the direction vector of the line, i.e. (1, -2, 3), is a normal vector to the plane.

Substituting the coordinates of the given point (3, 6, -7) and the components of the normal vector (1, -2, 3) into the equation of the plane, we get: 1(3) - 2(6) + 3(-7) = d => d = -24. Therefore, the equation of the plane is: x - 2y + 3z = -24

Given the chance of independent events, if one student is randomly selected from each class, the likelihood that both of them are female is 2/15.

Probability relates the number of favourable events to the total number of possible events.

Thus, to determine the chance of any event, the ratio between the number of favourable cases (cases in which event A may or may not occur) and the total number of potential cases is employed. A:

Number of likely cases x Number of potential cases equals probability.

The number of independently likely events.

Two occurrences A and B are said to be independent if and only if the likelihood of event B is unaffected by the occurrence of event A, or vice versa.

The sum of the probabilities for each individual event is the probability that every independent event, for any number of occurrences, will occur. In other words, if A and B are independent events, P(A and B) = P(A)P. (B).

The response indicates that Mr. Crawford's class has a total of 15 students (8 girls and 7 boys).

14 kids, 10 female and 4 males, are enrolled in Mrs. Ball's class.

The likelihood that a boy will be chosen in each class, if one student is randomly chosen from each, is computed as follows:

Probability in Mr. Crawford's class is 7/15 (7/15 x 15).

In Mrs. Ball's class, the probability is 4 14 = 4/14.

Given that these are separate occurrences, the likelihood that both students chosen for the classes are boys is determined as follows:

Chance that both of the students chosen for the classes will be boys: In Mr. Crawford's probability class In Ms. Ball's class, probability

Chance that both of the students chosen for the classes will be boys: 7/15 4/14

The likelihood that both of the students chosen for the classes are boys is 2/15.

Ultimately, there is a 2/15 chance that they are both boys.

Answer:

Sale Price = $36

Step-by-step explanation:

To find the sale price, you need to find what 10% of the original price is. 10% of $45 is $4.50. Now we need to find what 20% is, 20% is double 10% so we multiply the answer we got by 2. This equals to $9. The question is asking for the sale price, to find it you have to subtract $9 (the discount) from $45 (regular price). The answer you should get is $36.

Equation:
$45 ÷ 10 = $4.50
$4.50 × 2 = $9
$45 - $9 = $36

Answer:

A

Step-by-step explanation:

The equivalent expression is: \(-x^5 y^3 + 6x^3 y^5\).

Let's simplify the given expression step by step using the given terms:
Expression:

\(3x^3 y^5 + 3x^5 y^3 - (4x^5 y^3 − 3x^3 y^5)\)
Distribute the negative sign outside the parentheses to the terms inside:
\(3x^3 y^5 + 3x^5 y^3 - 4x^5 y^3 + 3x^3 y^5\)
Combine like terms, which are terms that have the same variables raised to the same power:
\((3x^3 y^5 + 3x^3 y^5) + (3x^5 y^3 - 4x^5 y^3)\)
Add or subtract the coefficients of the like terms:
\(6x^3 y^5 - x^5 y^3\)
So, the simplified expression is:
\(6x^3 y^5 - x^5 y^3\)

The formula to calculate the circumference of a circle is given by \(\displaystyle\sf C=2\pi r\), where \(\displaystyle\sf C\) represents the circumference and \(\displaystyle\sf r\) is the radius of the circle.

Given that the diameter of the above ground circular swimming pool is 30 ft, we can find the radius by dividing the diameter by 2. So, the radius \(\displaystyle\sf r\) would be \(\displaystyle\sf \frac{30}{2}=15\) ft.

Now, substituting the value of \(\displaystyle\sf r\) into the formula, we have:

\(\displaystyle\sf C=2\pi ( 15)\)

Using \(\displaystyle\sf \pi =3.14\), we can calculate the circumference:

\(\displaystyle\sf C=2( 3.14)( 15)\)

\(\displaystyle\sf C=2( 3.14)( 15)\)

\(\displaystyle\sf C=94.2\) ft

Therefore, the circumference of the pool is 94.2 ft.

Answer:

Options (B), (D) and (E)

Step-by-step explanation:

In the figure attached, a triangle has been given with interior angles x, y and z and exterior angle as w.

By the exterior angle theorem,

"Exterior angle formed by extending one side of a triangle is equal to the opposite two interior angles."

Therefore, x° + y° = w°

Since measure of angle w is equal to the sum of two angles x and y,

So, w° > x°

Similarly, w° > y°

Therefore, Options (B), (D) and (E) are the correct options.

Step-by-step explanation:

In summary the correct graph to represent this relationship is a straight line with a slope of 1/6.

How to solve?

As per the given information, on the scale model 2 inches represent 1 foot on the actual statue. This means that as we go up by 1 foot on the actual statue, we go up by 2 inches on the scale model.

Therefore, the relationship between the height of the actual statue and the height of the scale model is linear, with a slope of 2/12 = 1/6. This is because for every 1 foot increase in height on the actual statue, the height on the scale model increases by 2 inches, which is equivalent to 1/6 of a foot.

So, the correct graph to represent this relationship is a straight line with a slope of 1/6.

Looking at the given options, the graph that best represents this relationship is option (C), which is a straight line with a positive slope of less than 1.

Step-by-step explanation:

Step-by-step explanation:

The surface area of a rectangular prism can be found by adding the areas of all six of its faces.

In this case, the rectangular prism has side lengths of 3, 6, and 12 feet. So, its faces are:

Top and bottom faces: Each of these faces is a rectangle with side lengths of 3 feet and 6 feet. Therefore, the area of each of these faces is 3 ft * 6 ft = 18 ft². Since there are two of these faces, their combined area is 2 * 18 ft² = 36 ft².

Front and back faces: Each of these faces is a rectangle with side lengths of 3 feet and 12 feet. Therefore, the area of each of these faces is 3 ft * 12 ft = 36 ft². Since there are two of these faces, their combined area is 2 * 36 ft² = 72 ft².

Side faces: Each of these faces is a rectangle with side lengths of 6 feet and 12 feet. Therefore, the area of each of these faces is 6 ft * 12 ft = 72 ft². Since there are two of these faces, their combined area is 2 * 72 ft² = 144 ft².

To find the total surface area, we add the areas of all six faces:

Total surface area = 36 ft² + 72 ft² + 144 ft²

Total surface area = 252 ft²

Therefore, the surface area of the rectangular prism is 252 square feet.

Answer:

Step-by-step explanation:

12*3*2= 72 because there are two rectangles with the same length.

6*3*2= 36 because there are two widths with the same area.

6*12*2= 144 because there are a top and bottom with the same area.

72+36+144= 252

Surface area is 252 ft squared.
