Step-by-step explanation:
There would be 216 outcomes because
6*6=36 outcomes so
6*6*6, or 36*6, = 216.
When 3 fair dice are rolled then there are 216 possible outcomes.
What is mean by Probability?
The term probability refers to the likelihood of an event occurring.
Given that;
When 2 fair dice are rolled there are 36 possible outcomes.
Now,
Since, When 2 fair dice are rolled then possible outcomes = 6 x 6 = 36
So, When 3 fair dice are rolled then possible outcomes = 6 x 6 x 6
= 216
Thus, When 3 fair dice are rolled then there are 216 possible outcomes.

The local Walmart sold 67 televisions on Tuesday, 79 televisions on Wednesday, 195 televisions on Saturday, and 82 televisions on Sunday. How many televisions were sold in all over the weekend? The parking rates at the hospital's parking garage are 50 cents for the first hour and 25 cents for each additional hour. If Juan parks in the hospital's parking garage for 8 hours, how much will the total charge for parking be? Tom is on a diet. His diet plan allows him to have 1,000 calories for dinner. He's chosen a menu of enchiladas (537 calories), asparagus (96 calories), orange salad (78 calories), and cake (633 calories). If he eats this meal, will Tom be staying on his diet?
The total televisions sold over the weekend equals 177.
The cost of parking equals 50 cents for the first hour plus 25 cents for the additional 7 hours. Cost = .5 +7 x .25 = $2.25
In order to see if Tom is staying on his diet you need to add the total calories of the food that he is planning on eating for dinner. The total is 1,344 calories, so if he ate all of it he would not be staying on his diet.

Function f(x) is positive, increasing and concave up on the closed interval [a, b]. The interval [a, b] is partitioned into 4 equal intervals and these are used to compute the upper sum, lower sum, and trapezoidal rule approximations for the value of Integral b a f(x) dx. Which one of the following statements is true?
Lower sum < Trapezoidal rule Value < Upper sum
Lower sum < Upper sum < Trapezoidal rule value
Trapezoidal rule < Lower sum < Upper sum
Cannot be determined without the x-values for the partitions
The left sum would be f0+f1+f2+f3
The right sum would be f1+f2+f3+f4
The trapezoidal rule value is:
(f0+f1)/2 + (f1+f2)/2+(f2+f3)/2 +(f3+f4)/2
This would put the trapezoidal rule in the middle , which makes the answer:
Lower sum < Trapezoidal rule Value < Upper sum
Answer:
Step-by-step explanation:
Given function f(x) is positive, increasing and concave up on the closed interval [a, b],
it means f(x1) < f(x2) if x1 < x2
So Lower sum < Upper sum
As Trapezoidal is average of f(x1) and f(x2) = [f(x1) + f(x2)] / 2
it is average of the Lower and Upper sum.
The answer is Lower sum < Trapezoidal rule Value < Upper sum

that means-----> The translation is 2 units to the left and 3 units down
step 2
Position 2 is located at (1,2) and then go to position 3 at (-1,-1)
so
The rule of the translation Position 2 to Position 3 is
(x,y)-----> (x-2,y-3)
that means-----> The translation is 2 units to the left and 3 units down
step 3
Find the location of the 4th position
Applying the rule of the translation to position 3 at (-1,-1)

if i have 38 assignments and i do 15 of them what percentage do i have done?
Answer:
39.473%
Step-by-step explanation:
It is actually fairly simple to get the answer to this. What you can do to find any percentage, is to take the amount done, or whatever it is in the scenario, and divide it by the total. It is like turning it into a fraction, which you can do as well. Turn this into a fraction, and then convert it. 15/38, 15 divided by 38 = 39.473.
Hope this helped ^-^
To find the percentage you have done, divide the number you did by the total number you have to do:
15 / 38 = 0.3947
Multiply that by 100 to get the percentage:
0.3947 x 100 = 39.47% ( Round as needed).

Enter the system represented on the graph below. Find and explain the meaning of the point of intersection of the lines.
Answer:
y = -2x+4
y = (3/2)x -3
The point of intersection is (2, 0), or x=2 and y=0.
Step-by-step explanation:
The downward-sloping line drops 2 grid squares for each 1 it goes to the right, so its slope is -2. It intersects the y-axis at +4. In slope-intercept form, its equation is ...
y = slope · x + (y-intercept)
y = -2x + 4
Similarly, the upward-sloping line rises 3 grid squares for each 2 it goes to the right, so its slope is 3/2. It intersects the y-axis at -3. Its equation is ...
y = (3/2)x -3
The two lines intersect at the point where x=2 and y=0, so the coordinates are (2, 0). These are the values of x and y that satisfy both equations, so are the solution to the system.

Please help! The graph of function g(x) is a transformation of the graph of function f(x) = x^2.
g(x) = _________
A.) 2x^2+3
B.) -2x^2-3
C.) -1/2x^2-3
D.) 1/2x^2-3
Answer:
B.) -2x^2-3
Step-by-step explanation:
You only need to look at the values of the offered answers for x=1 in order to determine the correct one.
A.) for x = 1, 2·1+3 = 5
B.) for x = 1, -2·1-3 = -5 . . . . matches the graph
C.) for x = 1, -1/2·1-3 = -3 1/2
D.) for x = 1, 1/2·1-3 = -2 1/2
___
Comparing the values at x=1 to the values at x=0, you find that f(1)-f(0) = 1, while g(1)-g(0) = -2. This tells you the multiplier is -2, so matches choice B.
The fact that the vertex of g(x) is 3 units below that of f(x) tells you that -3 has been added to the product -2x^2.
_____
Comment on vertical scale factor
Since 1^2 = 1, it is often convenient to look at a point that is 1 unit away from the vertex of the function. The function value relative to the vertex value at that point will tell you the vertical scale factor.
For example, we know that the coefficient of x^2 is 1 in f(x), and we see on the graph that f(1) is 1 unit above the vertex at (0, 0). The value of g(1) is -5, which is 2 units below the vertex of g(x) at (0, -3). So, the vertical scale factor is -5-(-3) = -2.

Fine the measure of the angle formed by the radius and the side of a regular dodecagon.
A.15
B.30
C.60
D.75
Answer:
Option D.75°
Step-by-step explanation:
we know that
The sum of the interior angles of a regular dodecagon is equal to
[tex]S=(n-2)*180[/tex]
where
n is the number of sides
In this problem
n=12 sides
substitute
[tex]S=(12-2)*180[/tex]
[tex]S=1,800\°[/tex]
Find the measure of each interior angle
Divide the sum of the interior angles by the number of sides
[tex]1,800\°/12=150\°[/tex]
The measure of the angle formed by the radius and the side of a regular dodecagon is half the measure of the interior angle
therefore
[tex]150\°/2=75\°[/tex]
If the length of the rectangle is 15 units long and the width is 11 units long, how long is the diagonal
Answer:
18.6 units
Step-by-step explanation:
A rectangle is a four sided shape with 4 perpendicular angles. It has two pairs of parallel sides which are equal in distance: width and length. A diagonal can be drawn between opposite corners that splits the triangle into two equal right triangles. The distance of this diagonal is found using the Pythagorean Theorem a² + b² = c². In the rectangle a = 11 and b = 15. Substitute these values and simplify using a square root operation.
11² + 15² = c²
121 + 225 = c²
346 = c²
√346 = c
18.6= c

Suppose that in the town of Springfield, RI, the number of days per year with no measurable precipitation is approximately normally distributed with a mean of 85.1 days and a standard deviation of 7.5 days. Ms. Johnson, who lives on a farm just outside of Springfield, wonders if the mean number of days with no measurable precipitation on her farm is different from in town. Her grandfather maintained meticulous weather records. She obtains a simple random sample of eight years from her grandfather's records, and determines that the mean number of days with no measurable precipitation in those years was 82.3 days. She plans to conduct a one-sample ????z ‑test, assuming that the standard deviation of days with no measurable precipitation is the same at the farm as in town. Choose the appropriate null and alternative hypotheses for such a test.
Answer:
H0: µ = 85.1
Ha: µ ≠ 85.1
Step-by-step explanation:
She wants to see if the number of days is different. It could be higher or lower, so the alternate hypothesis uses the "not equal to" sign. If she wanted to see if it rained more on the farm, her alternate hypothesis would be
Ha: µ > 85.1
If she wanted to see if it rained less, then she would use the alternate hypothesis of Ha: µ < 85.1
The solution for the null hypothesis is given below,
H0: µ = 85.1
Ha: µ ≠ 85.1
What is the null hypothesis?When there are two possibilities then we calculate the null hypothesis if the hypothesis is true hypothesis is accepted if it is To conduct a hypothesis test for the above situation. We define the null hypothesis and the alternative hypothesis.
She is checking to see if the number of days has changed. The alternative hypothesis utilizes the "not equal to" marker since it might be either higher or lower. Her alternate hypothesis, if she wanted to determine whether it rained more frequently on the farm, is
Ha: µ > 85.1
If she wanted to see if it rained less, then she would use the alternate hypothesis of Ha: µ < 85.1.

Which of the following is a horizontal stretch of the parent function?
Answer:
C.
Step-by-step explanation:
Answer:
The correct option is 3.
Step-by-step explanation:
The parent function is
[tex]f(x)=|x|[/tex]
The horizontal stretch and compression is defined as
[tex]g(x)=|bx|[/tex]
If 0<b<1, then it is horizontal stretch and if b>1, then it is horizontal compression.
Graph 1 passing thought the point (1,-1).
[tex]-1=|b(1)|[/tex]
This statement is false for any value of b, because the value of modulus can not be negative.
Graph 2 passing thought the point (1,2).
[tex]2=|b(1)|[/tex]
[tex]2=b[/tex]
Since b>1, therefore this graph represent the horizontal compression.
Graph 3 passing thought the point (2,1).
[tex]1=|b(2)|[/tex]
[tex]\frac{1}{2}=b[/tex]
Since 0<b<1, therefore this graph represent the horizontal stretch.
Thus, the correct option is 3.

A kite is designed on a rectangular grid with squares that measure 1cm by 1 cm. A hexagonal piece within the kite will be reserved for the company logo. Use the grid to identify the perimeter and area of the space reserved for the logo.
Answer:
The answer is the first answer
P = 8 + 4√13 cm
A = 36 cm²
Step-by-step explanation:
* Lets study the figure
- Its a kite with two diagonals
- The shortest one is 12 cm
- The longest one is 26 ⇒ axis of symmetry of the kite
- the shortest diagonal divides the longest into two parts
- The smallest part is 8 cm and the largest one is 18 cm
* To find the area reserved for the logo divide
the hexagonal piece into two congruent trapezium
- The length of the two parallel bases are 4 cm and 8 cm and
its height is 3 cm
- The length of non-parallel bases can calculated by Pythagoras rule
∵ The lengths of the two perpendicular sides are 2 cm and 3 cm
- 3 cm is the height of the trapezium
- 2 cm its the difference between the 2 parallel bases ÷ 2
(8 - 4)/2 = 4/2 = 2 cm
∴ The length of the non-parallel base = √(2² + 3²) = √13
* Now we can find the area of the space reserved for the logo
- The area of the trapezium = (1/2)(b1 + b2) × h
∴ The area = (1/2)(4 + 8) × 3 = (1/2)(12)(3) = 18 cm²
∵ The space reserved for the logo are 2 trapezium
∴ The area reserved for the logo = 2 × 18 = 36 cm²
* The area of the reserved space for the logo = 36 cm²
* The perimeter of the reserved space for the logo is the
perimeter of the hexagon
∵ The lengths of the sides of the hexagon are:
4 cm , 4 cm , √13 cm , √13 cm , √13 cm , √13 cm
∴ The perimeter = 2(4) + 4(√13) = 8 + 4√13 cm
* The perimeter of the reserved space for the logo = 8 + 4√13 cm

The polygons are similar, but not necessarily drawn to scale. Find the value of x.
If the shapes are similar, the correspondent sides are in proportion:
[tex]AB\div DE = BC \div EF[/tex]
Let's plug the values and solve for x:
[tex]5x \div 5 = 4 \div x \iff \dfrac{5x}{5}=\dfrac{4}{x}\iff x = \dfrac{4}{x}[/tex]
Multiply both sides by x to get
[tex]x^2=4 \iff x=\pm2[/tex]
The only feasible solution, though, is [tex]x=2[/tex], because it wouldn't make sense to have negative lengths.
The value of x in the similar polygons in the given diagram is: B. x = 2.
What are the Sides of Similar Polygons?Similar polygons have the same shape but different size, thus, the length of their corresponding sides are proportional together and have equal ratio.
In essence, we will have the following ratio:

The high school leadership team is having a car wash. They charge $5.50 for large cars and $4.00 for small cars . They had a successful day, washed a total of 142 cars, and made $652.50. How many large cars and small cars did they wash?
Answer: 56 large cars and 86 small cars.
Step-by-step explanation:
Let's call:
[tex]l[/tex]: the number of large cars.
[tex]s[/tex]: the number of small cars.
Then, you can set up the following system of equations:
[tex]\left \{ {{l+s=142} \atop {5.50l+4.0s=652.50}} \right.[/tex]
You can use the Elimination Method:
- Multiply the first equation by -4.0
- Add both equations.
- Solve for l.
[tex]\left \{ {{-4.0l-4.0s=-568} \atop {5.50l+4.0s=652.50}} \right.\\--------\\1.5l=84.5[/tex]

[tex]y = \frac{4}{x + 6} + 2 \\ [/tex]
found by:
as value of x approaches -6 from left, value of y appoaches negative infinity
as value of x approaches -6 from the right, value of y approaches infinity
(undefined solution)
therefore, the value of x = 0 is translated to x = - 6
if x = -6,
(x + 6) = 0
(x + 6) is the value of x in the equation
[tex]y = \frac{4}{x + 6} + c[/tex]
as x increases, the value of 4/x approaches 0
in the graph, it approaches 2 instead
meaning 2 units is added to the value of y,
therefore c = 2.
