Answer:

Step-by-step explanation:

To determine what most likely happened in Sandy's experiment, we need additional data on the outcomes of the virtual coin tosses in each experiment. Without this data, we cannot directly compare the experimental probability to the theoretical probability.

However, we can make some general observations based on the law of large numbers and the concept of convergence. The law of large numbers states that as the number of trials or experiments increases, the experimental results tend to converge towards the theoretical probabilities. This means that with a larger number of flips, the experimental probability is more likely to be closer to the theoretical probability.

Therefore, based on this principle, it is reasonable to assume that Sandy's experimental probability was likely closest to the theoretical probability in the experiment with 1,000 flips. As the number of flips increases, the chances of the experimental results aligning closely with the theoretical probability increase.

However, it is important to note that without the specific data on the outcomes of each experiment, we cannot definitively determine which experiment had the experimental probability closest to the theoretical probability.

Answer:

12+15+50=77 inches²

Step-by-step explanation:

If each unit or cube is one inch, it will be (3x4x2)/2=12 inches² for the two triangles.

3x5=15 inches² for the rectangle.

And 5x5x2=50 inches² for the two bigger rectangles.

Answer:

Rectangle's is 28

Step-by-step explanation:

We multiply 9 * 4 to get rectangless shape and then we substract squares (2) shape 2*2*2

(9*4) - (2*2*2)= 28

Answer:

7:20 p.m.

Step-by-step explanation:

First, we can find the distance that each friend will be from their house at the time when they meet each other.

To find this, we can multiply the ratio [tex]8 \text{ mi} : 7 \text{ mi}[/tex] by a constant such that the sum of both numbers in the ratio is 20, since the friends' houses are 20 miles apart. Solving for this constant:

[tex]\dfrac{20}{7 + 8} \\ \\ = \dfrac{20}{15} \\ \\ \boxed{=\dfrac{4}{3}}[/tex]

Multiplying the constant by both sides of the ratio:

[tex]\dfrac{4}{3}\left(8 \text{ mi}) : (7 \text{ mi}\right)\dfrac{4}{3}[/tex]

[tex]\boxed{= \dfrac{32}{3} \text{ mi} : \dfrac{28}{3} \text{ mi}\right)}[/tex]

So, we know that the first friend will have traveled 32/3 or 10 2⁄3 miles when they meet, and the second friend will have traveled 28/3 or 7 1⁄3 miles.

Now, to calculate what time they will meet, we can divide how far one of the friends has traveled by how fast they were traveling. This will give us the minutes it will take them to get to the meeting place. We can then add that amount of minutes to 6:00 p.m. to calculate when they will meet.

I will use the fast friend (traveling at 8 mph).

[tex]\dfrac{32}{3} \text{ mi} \cdot \dfrac{60 \text{ min}}{8 \text{ mi}}[/tex]

— Also note that I substituted 1 hour for 60 minutes in the mph ratio.

[tex]= \dfrac{32}{3} \not\text{mi} \cdot \dfrac{60 \text{ min}}{8 \not\text{mi}}[/tex]

[tex]= \dfrac{32 \cdot 60}{3 \cdot 8} \text{ min}[/tex]

[tex]= \dfrac{32}{8} \cdot \dfrac{60}{3} \text{ min}[/tex]

[tex]= 4 \cdot 20 \text{ min}[/tex]

[tex]\boxed{= 80\text{ min}}[/tex]

Adding those minutes to 6:00, noting that 80 min = 1 hr 20 min:

[tex]\text{ } \ \, 6\!:\!00 \text{ p.m.}\\\underline{+ 1\!:\!20}\\\\\text{ }\, \boxed{7\!:\!20 \text{ p.m.}}[/tex]

So, the friends will meet at 7:20 p.m.

to get the equation of any straight line, we simply need two points off of it, let's use those two in the picture below.

[tex](\stackrel{x_1}{2}~,~\stackrel{y_1}{60})\qquad (\stackrel{x_2}{4}~,~\stackrel{y_2}{30}) ~\hfill \stackrel{slope}{m}\implies \cfrac{\stackrel{\textit{\large rise}} {\stackrel{y_2}{30}-\stackrel{y1}{60}}}{\underset{\textit{\large run}} {\underset{x_2}{4}-\underset{x_1}{2}}} \implies \cfrac{ -30 }{ 2 } \implies - 15[/tex]

Answer:224

Step-by-step explanation:

Okay as you can see, the figure is divided into 3 shapes. 2 rectangles and a right trapezoid.

You can solve the area of the rectangle on the far right by doing 9x6 leaving you with 54.

For the other rectangles you can do 11x12 equaling 132. I got 11 because you know the top is 17 and as you see at the bottom that length you used for the first rectangle is 6, so you do 17-6. You get 12 from adding 9+3.  

For the right trapezoid the formula is A = ( a + b ) x h/2. So you can plug it in and say A=(12+7) x 4/2= 38.

You then add all the areas together (54+132+38= 224) leaving you with the answer of 224.

Answer:

the surface area of the rectangular prism is found as : S = 275 ¹/₈ cm².

Length l = 11 ³/₄ cm = 47/4 cm = 11.75 cm

width w = 5 ³/₄ cm = 23/4 cm = 5.75 cm

height h = 4 cm

surface area of the prism S = 2(lw + wh + hl)

S = 2(11.75*5.75 + 5.75*4 + 4*11.75)

S = 2*137.5625

S = 275.125

S = 275 ¹/₈ cm²

Answer:

For A: The first function has a greater ROC

For B: The first function has a negative slope

Step-by-step explanation:

Explication for A:

We already know that the R.O.C. (slope) is 2 for the first function, so all we need to do is substitute the values in the table into the following formula: y2-y1/x2-x1

after substituting: (-3-(-6))/(0-(-1))

simplify 3/1=3, since the ROC is 3, the second equation has a greater ROC than the first

Explanation for B:

The first function described is f(x)=20-3.5x

This is because the y intercept is the starting point, or how much money she has in the gift card. She spends 3.5 dollars per week, so we add a variable to represent the number of weeks, and its negative since she is spending, not earning. We also know that the slope is negative since y is decreasing as x is increasing, on the table.

The second function described is c(m)=5x+10

This is because the equation represents the total cost of renting a calculator, so both terms are positive.

Answer:

See below

Step-by-step explanation:

1. The rule defining the function on the graph:

y = x -1, if x = (-3,-1)

y = -3x + 9, if x = [2, 4)

2. f(x) = |4x + 36|

y = 4x + 36, if x ≥ - 9

y = -4x - 36, if x < - 9

3. See attachment for the graph

4. Item 4 is not included in the question

Answer:

4t

Step-by-step explanation:

you times the amount of students by the cost of the admission

The total amount that Hailey paid can be represented by the following expression in terms of x:

Total amount = x + 0.07x + 0.20(x + 0.07x)

Simplifying the equation, we get:

Total amount = x + 0.07x + 0.20(1.07x)

Total amount = x + 0.07x + 0.214x

Total amount = 1.284x

Therefore, the expression in terms of x that represents the total amount that Hailey paid is 1.284x.

If You are talking about 0.45 with the line over 5 ,that means the five is repeating and it nevers stops

Step-by-step explanation:

Answer:

F : y = -x + 4

Step-by-step explanation:

The first observation about this scatterplot is that the best line of fit will be a line going diagonally from top left to bottom right(or bottom right to top left)

Such a line has negative slope

Equation will be of the form

y = mx + b where m is a negative number

We can eliminate H and I since both lines have a positive slope which means that the line will go in a diagonal bottom left to top right direction

Let's examine options F and G

F:  y = - x + 4
G: -9x + 3

Plug in some values for x from the graph and see which of the lines comes closest to the  y values  computed from the equations

At x = -5, the y value from the graph appears to be either 7 or 8

F: y = -x + 4 ==> -(-5) + 4 = 5 + 4 = 9; pretty close to graph's point value

G: -9x + 3 ==> -9(-5) + 3 = 45 + 3 = 48; this is greatly different from the graph value

At x = 0; the y value from graph is close to 4

From the equations we get
F: y = -x + 4 ==>  y = -(0) + 4 = 4; pretty darn close

G: y  -9x + 3 => y = -9 + 3 = -6; large difference

One more point
At x = 20, the point on the graph appears to be close to -19

From the equations we get

F: y = -x + 4 = -20 + 4 = -16; not too different

G: y = -9x + 3 = -9(20) + 3 = -180 + 3 = 177; way off

So the best line of fit would be

F : y = -x + 4

The equation that best represents the line of fit from the scatter plot is given as follows:

y = -x + 4.

The slope-intercept representation of a linear function is given by the equation shown as follows:

y = mx + b

The coefficients m and b have the meaning presented as follows:

From the scatter plot, we have that when x = 0, y = 4, hence the intercept b is given as follows:

b = 4.

When x = 20, y is approximately -16, hence the slope m is obtained as follows:

-16 = 20m + 4

20m = -20

m = -1.

Hence the function is:

y = -x + 4.

Question:

What solid figure did Odessa make?

Answer:

Pyramid

No it cannot. There are a couple of ways to prove this. The easiest way is that we know by looking at the angles that we have an Isosceles triangle, because we have 2 angles of the same value. We know that an Isosceles triangle must have at least 2 sides of the same length, which means that this triangle cannot have the side lengths listed.
