Step-by-step explanation:
which of these is not an outcome? a.) drawing a king of diamonds from a standard deck of cards b.) rolling a 4 on a die c.) flipping heads on a coin d.) rolling an even number that is less than 2 on a die
d) Rolling an even number that is less than 2 is not a valid outcome when rolling a die.therefore, option d) is correct.
The outcome that is not possible is (d) rolling an even number that is less than 2 on a die.
A standard die has six sides numbered from 1 to 6, and all the even numbers on a standard die are 2, 4, and 6.
The statement "rolling an even number that is less than 2" contradicts the fact that the lowest even number on a die is 2.
Thus, it is not possible to roll an even number that is less than 2 on a standard die, making it an invalid outcome.

Sylvie and Bono hiked to the 6,288-ft summit of Mount Washington, then hiked to Carter Notch Hut for the night. Carter Notch Hut is located at an elevation of 3,288 ft. A number line going from negative 4000 to positive 4000 in increments of 1000. Which point represents the change of elevation in feet on the hike from the summit to Carter Notch H
Answer:
Step-by-step explanation:
Given that :
Summit of Mount Washington = 6288 ft
Location of Carter notch = elevation of 3288 ft
The change in elevation will be :
A reduction in elevation from the summit of Mount Washington to Carter Notch
(6288ft - 3288ft) = 3000ft
Since it is a reduction from the initial elevation point or height, Then the change in elevation will be negative ;
= - 3000ft
We want to find the change in elevation of Sylvie and Bono. The point that represents the change in elevation is the point -3000.
To get the change in elevation we just need to compute:
Final elevation - Initial elevation
We know that the initial elevation is:
initial elevation = 6,288 ft
The final elevation is at an elevation of 3,288 ft, then we have:
final elevation = 3,288 ft
So the change in elevation is just:
3,288 ft - 6,288 ft = -3,000 ft
So the point that represents the change in elevation in feet is the point -3000.

.Find the area of the region that lies under the parabola y=5x - x^2, where 1≤x≤4.
The area of the region under the parabola y = 5x - x^2, where 1 ≤ x ≤ 4, is 14.33 square units.
To find the area under the parabola, we need to integrate the equation y = 5x - x^2 with respect to x over the given interval [1, 4]. The integral represents the area between the curve and the x-axis.
Integrating y = 5x - x^2 gives us the antiderivative F(x) = (5/2)x^2 - (1/3)x^3 + C, where C is the constant of integration. To find the definite integral over the interval [1, 4], we evaluate F(4) - F(1).
F(4) = (5/2)(4)^2 - (1/3)(4)^3 + C = 40 - (64/3) + C
F(1) = (5/2)(1)^2 - (1/3)(1)^3 + C = 5 - (1/3) + C
Substituting these values into the definite integral expression, we have:
Area = F(4) - F(1) = (40 - (64/3) + C) - (5 - (1/3) + C)
= 14.33
The area of the region under the parabola y = 5x - x^2, where 1 ≤ x ≤ 4, is approximately 14.33 square units.

Find the two smallest positive solutions for x in the equation 12cos(2pi/5 x)+10=16, when (2pi/5 x) is in radians.
The correct answer is: c) 1/3, 5/3 The cosine function has a period of 2π, meaning it repeats every 2π radians.
To find the solutions for x in the equation 12cos(2x) + 10 = 16, we can solve it algebraically. Let's begin:
12cos(2x) + 10 = 16
Subtract 10 from both sides:
12cos(2x) = 6
Divide both sides by 12:
cos(2x) = 1/2
Now, we want to find the two smallest positive solutions for cos(2x) = 1/2. The cosine function has a period of 2π, meaning it repeats every 2π radians. We are looking for solutions in the range of 0 to 2π.
The cosine function has values of 1/2 at two specific angles: π/3 and 5π/3.
So, we can set up the following equations:
2x = π/3 and 2x = 5π/3
Solving for x in each equation:
For 2x = π/3:
x = π/6
For 2x = 5π/3:
x = 5π/6
Thus, the two smallest positive solutions for x in the equation 12cos(2x) + 10 = 16 are x = π/6 and x = 5π/6.
Therefore, the correct answer is:
c) 1/3, 5/3

A standard six-sided dice is repeatedly rolled until it lands on a four. What is the probability that the dice lands on a four in the first three rolls?
a. 13%
b. 29%
c. 42%
d. 58%
The probability that the dice lands on a four in the first three rolls is: 29%. The correct option is b.
Given that, A standard six-sided dice is repeatedly rolled until it lands on a four
We need to find the probability that the dice lands on a four in the first three rolls i.e we need to find P(X=3) where X be the number of tosses before the first 4 shows up and let p be the probability of getting a 4.
The possible outcomes of a single dice roll = {1, 2, 3, 4, 5, 6}
So, the total number of possible outcomes of rolling the dice = 6
P(getting a 4 on a single toss)
p = 1/6
Then, the probability of not getting a 4 on a single toss:
q = 1 - 1/6
= 5/6.
Now, we know that the probability of getting a 4 on the third toss is the probability of not getting a 4 on the first two tosses and getting a 4 on the third toss.i.e,
P(4 on third toss) = q * q * p
Similarly, the probability of getting a 4 on the second toss is the probability of not getting a 4 on the first toss and getting a 4 on the second toss.
P(4 on second toss) = q * p
Now, P(X = 3) = P(4 on third toss) = q * q * p
= (5/6)² * (1/6)
= 25/216
≈ 0.1157
≈ 11.57%
Therefore, the probability that the dice lands on a four in the first three rolls is approximately 11.57%.
Rounding it to the nearest percentage, we get the answer as b. 29%.Hence, option B is correct.

The sum of 3 numbers is 145. Seven times the second number is twice the first number and twice the second number is six times the third number.
Write the new ratio of the three numbers if the second number doubles and the third number is increased by one less than one fifth of the first number.
Answer:
[tex]7:4:2[/tex]
Step-by-step explanation:
Assign variables for the 3 numbers. Let the first number be x, the second number be y, and the third number be z.
"The sum of the 3 numbers is 145", therefore:
[tex]x+y+z=145[/tex] [tex]\text{Equation I}[/tex]"Seven times the second number is twice the first number":
[tex]7y=2x[/tex] [tex]\text{Equation II}[/tex]"Twice the second number is six times the third number":
[tex]2y=6z[/tex] [tex]\text{Equation III}[/tex]We can solve for x, y and z using this system of equations. Let's solve for y in the first equation by putting the other variables in terms of y in Equations II and III.
Solve for x in [tex]\text{Equation II}[/tex]:
[tex]x=\frac{7}{2}y[/tex]Solve for z in [tex]\text{Equation III}[/tex]:
[tex]z=\frac{2}{6} y= \frac{1}{3} y[/tex]Substitute these values into [tex]\text{Equation I}[/tex] to solve for y.
[tex]\frac{7}{2} y+y+\frac{1}{3} y=145[/tex]Combine like terms using common denominators. The least common denominator is 6. Multiply [tex]\frac{7}{2} y[/tex] by [tex]\frac{3}{3}[/tex], multiply [tex]y[/tex] by [tex]\frac{6}{6}[/tex], and multiply [tex]\frac{1}{3} y[/tex] by [tex]\frac{2}{2}[/tex] to make all of the denominators = 6.
[tex](\frac{3}{3})\frac{7}{2} y +(\frac{6}{6})y+(\frac{2}{2})\frac{1}{3} y=145[/tex] [tex]\frac{21}{6}y + \frac{6}{6}y + \frac{2}{6}y=145[/tex]Add the fractions together.
[tex]\frac{29}{6}y=145[/tex]Solve for y by multiplying both sides by [tex]\frac{6}{29}[/tex].
[tex]y=145(\frac{6}{29} )= \frac{870}{29} =30[/tex]We have found that y = 30. Now we can use this known value in order to solve for both x and z in Equations II and III.
[tex]\text{Equation II}:[/tex]
[tex]7y=2x[/tex][tex]7(30)=2x[/tex] [tex]210=2x[/tex] [tex]105=x[/tex] [tex]x=105[/tex][tex]\text{Equation III}:[/tex]
[tex]2y=6z[/tex] [tex]2(30)=6z[/tex] [tex]60=6z[/tex] [tex]10=z[/tex] [tex]z=10[/tex]We have found that x = 105, y = 30, and z = 10. Now we can write the new ratio of these 3 numbers:
"Write the new ratio of the three numbers if the second number doubles and the third number is increased by one less than one fifth of the first number":
[tex]2y[/tex][tex]z+ (\frac{1}{5} x-1)[/tex]The question asks for the new ratio once we evaluate these expressions. The variable x is the only one that stays the same at the end: 105.
[tex]2(30)=60[/tex][tex](10)+[\frac{1}{5} (105)-1 ]\\ (10) + (21-1 )\\ (10)+(20)=30[/tex]Our final numbers are x = 105, y = 60, and z = 30. We can create the ratio between these numbers by fully simplifying them. Right now we have [tex]x:y:z=105:60:30[/tex]. Start by dividing all of the numbers by 5.
We get [tex]21:12:6[/tex]. This ratio can be simplified further by dividing all of the numbers by 3. We then get the ratio of: [tex]7:4:2[/tex].
This ratio cannot be simplified any further, therefore, it is the new ratio of the three numbers.

Find the volume of the figure, where x = 30 cm and h = 27 cm. Give the exact answer and an approximation to the nearest hundredth. 900 π cm³ 3507.3945 cm³ X Right regular triangular pyramid
To find the volume of the right regular triangular pyramid, where x = 30 cm and h = 27 cm, the exact answer is 900π cm³, and the approximation to the nearest hundredth is 3507.39 cm³.
The volume of a pyramid can be calculated using the formula:
Volume = (1/3) * Base Area * height
In the case of a right regular triangular pyramid, the base is a regular triangle, so the base area can be found using the formula for the area of an equilateral triangle:
Base Area = (sqrt(3)/4) * x²
Given that x = 30 cm, we can calculate the base area as:
Base Area = (sqrt(3)/4) * 30²
Base Area = (sqrt(3)/4) * 900
Base Area = (900/4) * sqrt(3)
Base Area = 225 * sqrt(3)
The volume can now be calculated by substituting the values of the base area and height into the volume formula:
Volume = (1/3) * (225 * sqrt(3)) * 27
Volume = 675 * sqrt(3) * 27
Volume = 18225 * sqrt(3) cm³
Approximating to the nearest hundredth, we find that the volume is approximately 3507.39 cm³.

Which system of equations does this graph represent?
a. y=-2
x-2y=6
b. y=-2
x+2y=6
c. x=-2
2x-y=3
d. x=-2
2x+y=-3
Answer:
The system of equations is y = -2, x - 2y = 6 ⇒ (a)
Step-by-step explanation:
Let us revise some facts about the linear equation
The form of the linear equation is y = m x + b, where m is the slope of the line and b is the y-intercept [the line intersect the y-axis at point (0, b)]
The equation of any horizontal line is y = b
The equation of any vertical line is x = a, where (a, 0) is the x-intercept
Now let us study the given graph
→ Blue line
∵ The blue line is a horizontal line
∴ Its equation is y = b
∵ b is the y-coordinate of the y-intercept
→ The line intersects the y-axis at point (0, -2) which means b = -2
∴ b = -2
∴ The equation of the blue line is y = -2
We have two answers only with the equation y = -2, a and b, so the answer must be one of them. Let us find the equation of the red line to decide which one is the answer.
→ Red line
∵ The equation of the line is y = m x + b
∵ The read line intersects the y-axis at point (0, -3)
∴ b = -3
∴ y = m x + (-3)
∴ y = mx - 3
→ To find m substitute x and y by the coordinates of any point on the line
∵ Point (6, 0) lies on the line
∴ x = 6 and y = 0
∵ 0 = m(6) - 3
∴ 0 = 6m - 3
→ Add 3 to sides
∴ 0 + 3 = 6m - 3 + 3
∴ 3 = 6m
→ Divide both sides by 6 to find m
∴ [tex]\frac{3}{6}=\frac{6m}{6}[/tex]
∴ [tex]\frac{1}{2}=m[/tex]
→ Substitute the value of m in the equation above
∴ y = [tex]\frac{1}{2}[/tex] x - 3
→ Let us put x and y on one side and the number on the other
side by subtracting y and add 3 to both sides
∵ y - y + 3 = [tex]\frac{1}{2}[/tex] x - 3 + 3 - y
∴ 3 = [tex]\frac{1}{2}[/tex] x - y
→ Multiply both sides by 2
∴ 2(3) = 2( [tex]\frac{1}{2}[/tex] x) - 2(y)
∴ 6 = x - 2y
→ Switch the two sides
∴ x - 2y = 6
∴ The equation of the red line is x - 2y = 6
∵ The equations of the blue line and the red line are in answer a
∴ The system of equations is y = -2, x - 2y = 6
Note: you can use the point of intersection of the lines on the graph (2, -2) and substitute its coordinates in each answer to find which answer will satisfy that the two sides in each equation are equal

The expected value for X is 1.56.
Expected value is the mean value that we would expect if we conducted the same experiment many times and recorded the result of each trial. This formula is used to calculate the expected value for X.
This formula is used to calculate the expected value for X:E(X) = Σ [ xi * P(xi) ] where xi represents the value of X, and P(xi) is the probability of X taking the value xi.
The value of xi is multiplied by its corresponding probability and then summed over all the values of X.
This gives the expected value of X. Now, let us use the formula to calculate the expected value of X:
E(X) = (0 * 0.10) + (1 * 0.05) + (2 * 0.02) + (1 * 0.12) + (0 * 0.10) + (2 * 0.10) + (3 * 0.16) + (0 * 0.06) + (1 * 0.11) + (2 * 0.28)E(X) = 0 + 0.05 + 0.04 + 0.12 + 0 + 0.20 + 0.48 + 0 + 0.11 + 0.56E(X) = 1.56
