If Mira had spent the same total amount of time but an equal amount of time on each problem, each problem would have taken around 2.36 minutes.

In the given plot, Mira spent varying amounts of time on each of the 55 math problems. To find out how many minutes each problem would have taken if Mira had spent an equal amount of time on each problem, we need to calculate the total time she spent and divide it by the number of problems.

Looking at the plot, we can estimate the total time Mira spent by counting the dots above each tick mark and multiplying them by the corresponding time interval. Let's break it down step by step:

The tick marks on the plot are at 7, 7.5, 8, 8.5, 9, 9.5, and 10 minutes per problem.

There are 2 dots above the unlabeled tick mark between 8 and 8.5 minutes per problem. We can assume it represents 8.25 minutes.

There are 3 dots above the 9.5 minutes per problem tick mark.

Now, let's calculate the total time Mira spent:

(7 * 2) + (7.5 * 2) + (8 * 2) + (8.25 * 2) + (9 * 2) + (9.5 * 3) + (10 * 2) = 129.5 minutes.

Since Mira spent a total of 129.5 minutes on 55 problems, each problem would have taken approximately 2.36 minutes (rounded to two decimal places) if she had spent an equal amount of time on each problem.

From the given quadratic equation, we have that:

A quadratic equation is modeled by the following rule:

y = ax^2 + bx + c

The vertex has these following coordinates.

\((x_v, y_v)\)

In which:

Considering the coefficient a, we have that the vertex can represent either a maximum or a minimum point, as follows::

For this problem, the function is:

h(t) = -16t² + 160t + 200.

Then the coefficients are:

a = -16, b = 160, c = 200.

And the maximum height, in feet, will be of:

\(y_v = -\frac{160^2 - 4(-16)(200)}{4(-16)} = 600\)

The ball hits the ground for the positive root when h(t) = 0, hence after 8.9 seconds.

The given figure is composed of 2 triangles, each with a base of 10 inches and a height of 5 inches.

The area of a triangle is half the product of its base and height.

Therefore, the area of the composite figure can be calculated as follows:

\(\begin{aligned}\textsf{Area of compositie figure}&=\sf Area_{Triangle\;1}+Area_{Triangle\;2}\\\\&=\dfrac{1}{2} \cdot 10 \cdot 5 + \dfrac{1}{2} \cdot 10 \cdot 5\\\\&=5\cdot 5+5\cdot 5\\\\&=25+25\\\\&=50\; \sf square\;inches\end{aligned}\)

Therefore, the area of the composite figure is 50 square inches.

\(\hrulefill\)

The given figure is composed of a rectangle with width of 6 cm and length of 10 cm, and a triangle with base of 10 cm and height of 5 cm.

The area of a rectangle is the product of its width and length.

The area of a triangle is half the product of its base and height.

Therefore, the area of the composite figure can be calculated as follows:

\(\begin{aligned}\textsf{Area of compositie figure}&=\sf Area_{Rectangle} + Area_{Triangle}\\\\&=6 \cdot 10+\dfrac{1}{2} \cdot 10 \cdot 5\\\\&=60+5 \cdot 5\\\\&=60+25\\\\&=85\; \sf square\;centimeters\end{aligned}\)

Therefore, the area of the composite figure is 85 square centimeters.

The magnitude of the resultant of the two velocity vectors that are at right angles to each other is approximately 141.42 km/h.

we can use the Pythagorean theorem. According to the theorem, the magnitude of the resultant is equal to the square root of the sum of the squares of the magnitudes of the two vectors. we can write:

magnitude of the resultant = sqrt ((magnitude of vector 1) ^2 + (magnitude of vector 2) ^2)

magnitude of the resultant = sqrt ((100 km/h) ^2 + (100 km/h) ^2)

magnitude of the resultant = sqrt (2(100 km/h) ^2)

magnitude of the resultant = sqrt (2) * 100 km/h

Using a calculator, we can evaluate the square root of 2 to get:

magnitude of the resultant ≈ 141.42 km/h

f. cross-sectional sample survey

Step-by-step explanation:

- longitudinal cohort study is when the group of subjects that comprises the cohort is chosen based on a disease or injury and is then monitored over time at routine intervals. In this question, it's not the case as the sample of men were just picked and studied with no special group or cohort.

- If it was case-control observational study, the research would have started with identifying those who have heart failure and those who don't have heart failure but it wasn't the case and thus this is not correct.

- If this was voluntary response sample, it means the men would have been self chosen which means they volunteered to be part of the study if it was of interest to them. But this is not the case here.

- If it was completely randomized experiment, it means that the people sampled would have been randomly assigned to different treatments which was not so in this question.

- If it were to be match pairs experiment, it means the men sampled would be grouped into pairs and each pair will be assigned different treatments which didn't happen in this question.

- If it were to be cross-sectional sample survey, it means that data will be collected from a population of interest to make inferences from that population at a point in time. That is the case here because data about sedentary time or less was taken and compared to know the effect it had on heart failure.

- If it were census, it will just be about getting the size of the population without making inquiries about sedentary time.

Equation of the line passing through the point (-6,-3) and perpendicular to  the line passing through (-2,7) and (6,5) is y = 4x -19.

First we will find the slope of the line passing through (-2,7) and (6,5).

Slope of the line = (5-7)/(6-(-2)) = -2/8 = -1/4.

We know that,

Product of the slopes of two perpendicular lines = -1.

Let the equation of the line we have to find be y = mx + c.

Slope will be m.

Hence, we can write,

m*(-1/4) = -1

m = -1*(-4/1)

m = 4

Putting (6,5)  and m = 4 in y = mx + c , we get

5 = 4*(6) + c

5 = 24 + c

c = 5 - 24 = -19

Answer:

c) If the dimensions of a cube are doubled, the surface area is quadrupled and the volume is multiplied by 8.

Step-by-step explanation:

The surface area of a cube is the total area of its six faces.

Since all six faces of a cube are congruent squares, the surface area can be calculated by multiplying the length of one side (s) by itself and then multiplying the result by 6.

\(\boxed{\textsf{Surface area of a cube}=6s^2}\)

The volume of a cube can be calculated by multiplying the length of one side (s) by itself twice, or by raising it to the power of 3.

\(\boxed{\textsf{Volume of a cube}=s^3}\)

When the dimensions of a cube are doubled, the length of each side becomes twice its original length (2s).

\(\begin{aligned}\textsf{Surface area}&=6(2s)^2\\&=6\cdot 2^2 \cdot s^2\\&=6 \cdot 4 \cdot s^2\\&=\boxed{4 \cdot 6s^2}\end{aligned}\)

\(\begin{aligned}\textsf{Volume}&=(2s)^3\\&=2^3\cdot s^3\\&=\boxed{8\cdot s^3}\end{aligned}\)

Therefore, if the dimensions of a cube are doubled, the surface area is quadrupled and the volume is multiplied by 8

If α is an ordinal and β ∈ α, then β satisfies all three properties of an ordinal. Therefore, β is also an ordinal.

To prove the statement "If α is an ordinal and β ∈ α, then β is an ordinal," we need to demonstrate that if α is an ordinal and β is an element of α, then β satisfies the three properties of an ordinal:

Well-Ordering: Every element of β is strictly well-ordered by the membership relation ∈. This property holds because α is an ordinal and satisfies the well-ordering property, and β being an element of α inherits this property.

Transitivity: For any two elements γ and δ in β, if γ ∈ δ and δ ∈ β, then γ ∈ β. Since β is an element of α and α is transitive, the transitivity property carries over to β.

Trichotomy: For any two elements γ and δ in β, either γ ∈ δ, δ ∈ γ, or γ = δ. Again, this property is inherited from α, as β is an element of α.
