The highest variation in the temperature if found for Utah.
What is defined as the temperature variation?Temperature is the degree to which an object is hot or cold.In weather forecasting, daily temperature variation refers to the difference between a high and a low air temperature on the same day.There are many factors that contribute to temperature variations in the atmosphere. Temperature fluctuations are caused by four natural factors: latitude, altitude, location from the sea, as well as ocean currents.For the given question;
The maximum and minimum temperatures of the U.S states are given;
The variation in temperature is found by;
Temperature variation = Maximum temperature - Minimum temperature
Alaska = 100 - (-80) = 180
Idaho = 118 - (- 60) = 160
Nevada = 125 - (-50) = 175
Utah = 117 - (-69) = 186

A group of students is playing a game of El Repollo, which involves passing a ball made of layers of paper. After catching the ball, a player peels off a layer of paper, answers a question that has been written on the paper, and then tosses the ball to the next player. . Sara tosses the ball to Alex from a height of 1.5 meters. • The ball reaches its highest point about 1 second later. • Alex misses the ball, and it hits the ground 2 seconds after Sara tosses it to him. Which function approximates the height of the ball, in meters, a seconds after Sara tosses it to Alex? f(x) = -5z²+9.25z + 1.5 f(x) = 5(x-1.5)(x-2) f(x) = -5x(x - 2) f(z) = 5x² -10.75z + 1.5
The quadratic function that approximates the height of the ball, in meters, seconds after Sara tosses it to Alex is:
y = ax² + bx + 1.5.
What is a quadratic function?A quadratic function is defined according to the following rule:
y = ax² + bx + c.
Considering the context of this problem, we will use equations to find the coefficients.
Sara tosses the ball to Alex from a height of 1.5 meters, meaning that the initial height is of 1.5 meters, thus the coefficient c has a value of 1.5, and:
y = ax² + bx + 1.5.
The ball reaches its highest point about 1 second later, hence the x-coordinate of the vertex is calculated as follows:
xv = -b/2a = 1
-b = 2a
b = -2a
The ball hits the ground 2 seconds after Sara tosses it to him, hence y(2) = 0, that is:
0 = 4a + 2b + 1.5
4a + 2b = -1.5.
2a + b = -1.5.
2a - 2a = -1.5.

not all tiles would be used, need help solving the steps for a bisecting line statement.
We have different steps for bisecting a line segment using a reflective device, and these steps are as follows:
And we have to select three of them to complete the process.
To determine the steps, we need to remember that the reflective device permits us to see through it, and also see reflections on it. Then the steps for bisecting a line segment AB are:
1. Place the reflective device anywhere on the segment - It does not matter the position at which we need to put the reflective device.
2. Move the reflective device around on the paper until the reflection of point A coincides with point B.
3. Draw the line of the reflection using the edge of the reflective device as a guide.
Therefore, in summary, the three steps are:
• Place the reflective device anywhere on the segment (,first box,).
,• Move the reflective device around on the paper until the reflection of point A coincides with point B (,third box,).
• Draw the line of the reflection using the edge of the reflective device as a guide (sixth box),.

The probability that the student guesses 3 question correctly is 0.234 and the probability that the student guess more than one correctly is 0.7.
Using the property of binomial distribution we can calculate that the probability that a answer is correct is 0.25
As there are 4 options , hence we will see that probability that an option picked is correct is 1/4 = 0.25
Now we have to find the probability for 3 answers to be correct .
We will use the formula
[tex]P(X=x) = \frac{n!} {x! (n - x)!} \cdot p^x \cdot (1 - p)^{n - x}[/tex]
Now putting the values of x = 3 and the value of p = 0.25 we get
P(X = 3) = 0.234
therefore the value of P(3) = 0.234
Now we have to find the value of P(x>1)
Using the same formula we calculate the occurrence of the event
P(x>1)=1-P(x≤1)
or, P(x>1) = 0.7
Hence the required probability is 0.7.

Antonio buys persian rugs and then resells them for 150%
of his cost. If he bought a 4' by 9' rug $120, for how much
will he resell it?
Answer:
$180
Step-by-step explanation:
So first we need to know that 100% would be $120 because that was 100% of the price. Selling it for half the price is the same as selling it for 50%. So what we will be doing is we are going to sell the whole carpet - we are just going to sell it for half of $120. Now we need to thinking what would half the price be because half the price is the same as 50%. So 120/2 = $60 so if we have 100 percent (so $120) plus 50% (which is $60) the total we sold it for would be $180. Therefore our final answer would be $180.
3. Given: BAM is a right angle. If m BAM=4x+22, then solve for the value of x.
Right angle means that the angle is equal to 90 degrees
We will thus proceed by equating BAM = 90 degrees, we have:
[tex]\begin{gathered} 4x+22=90 \\ \text{Subtract 22 from both sides, we have:} \\ 4x+22-22=90-22 \\ 4x=68 \\ \text{divide through both sides by 4, we have:} \\ \frac{4x}{4}=\frac{68}{4} \\ x=17^{\circ} \end{gathered}[/tex]x = 17
Answer: 17 degrees
Step-by-step explanation:
<BAM is a right angle. A right angle is defined to be 90 degrees.
So...
<BAM = 4x + 22 is transformed to 90 = 4x + 22
90 = 4x + 22

Given the number 133, we list the first prime numbers and then look for a possible factor of 133:
Prime_list = {2, 3, 5, 7, 11, ...}
133 is not an even number, so we discard 2. 133 does not end with 0 or 5, so 5 can not be a factor. We evaluate 3, 7, and 11:
The only division with no rest is 133/7 = 19, and we know that 7 and 19 are prime numbers. We conclude that 133 is composite and can be represented as a product of 7 and 19:

What is Pythagoras Theorem?The right-angled triangle's relationship between its sides is explained by the Pythagorean Theorem, often known as Pythagoras Theorem, a key concept in mathematics.
The Pythagorean triple describes the sides of the right triangle. For the most part, the Pythagorean theorem is employed to determine a triangle's angle and the length of an ambiguous side.
The base, perpendicular, and hypotenuse formulas are derived by means of this theorem. The perpendicular, base, and hypotenuse of this triangle are its three named sides.
As it is on the other side of the angle of 90 degrees, the hypotenuse in this case is the longest side.
An equation, commonly known as a Pythagorean triple, is created by squared values for the sides of a right triangle that have positive integer values.
Let the Height of the Christmas tree be 'h' meters.
Length of the wire = (h + 9) meters
Distance from the base = (h - 23) meters
This scenario forms a right-angled triangle, with height = h m, base = (h-23) m and hypotenuse = (h+9) m
Now, as this is a right-angled triangle,
h^2 + (h-23) ^2 = (h+9) ^2 (Pythagoras theorem)
⇒ h^2 + h^2 - 46h + 529 = h^2 + 18h + 81
⇒ 2h^2 - h^2 - 46h - 18h = 81 - 529
⇒h^2 - 64h = -448
⇒ h^2 - 64h + 448 = 0
⇒ h^2 - (56 + 8) h + (56 x 8) = 0
⇒ (h - 56) x (h - 8) = 0
⇒ h = 56 or h = 8
Since the distance from the base = (h - 23) m cannot be a negative value,
therefore, h = 56 m
Therefore,
The height of the tree = 56 m,
The length of the wire = h + 9 = 56 + 9 = 65 m
The distance from the base of the tree to the wire = h -23
= 56 - 23 = 33 m

The probability that she does not choose a Stephen king novel is 12/17.
What is probability?
Probability is a measure of the likelihood of an event to occur. Many events cannot be predicted with total certainty. We can predict only the chance of an event to occur i.e., how likely they are going to happen, using it. Probability can range from 0 to 1, where 0 means the event to be an impossible one and 1 indicates a certain event.
Given,
1) total books no shelf = 17
Novel of Stephen king = 5
The probability of stephen king = 5/17
The probability of not choosing Stephen novel = 1-5/17
= (17-5)/17
=12/17
2) total number of executives = 11
Number of men = 5
Number of women = 6
probability of a man = 5/11
Probability of a woman = 6/11
Given, one woman and 3 men are selected
therefore, using combination.
Total combinations = n! / (r! x (n - r)!)
n = 4
r = 3
Therefore, probability = n! / (r! x (n - r)!)[tex](5/11)^{1} (6/11)^{3}[/tex]

Given :
A wheelchair ramp is 4.2 meters long.
It rises 0.7 meters
So, let the angle of elevation = x
so,
[tex]\begin{gathered} \tan x=\frac{0.7}{4.2}=\frac{1}{6} \\ \\ x=\tan ^{-1}\frac{1}{6}=9.462 \end{gathered}[/tex]Rounding the answer to the nearest tenth
So, the answer is : the angle = 9.5
Find the y-intercept of the line on the graph.
The y-intercept of the line on the graph is -2.
What is termed as the y-intercept?The point at which the graph intersects a y-axis is known as the y-intercept. Finding the intercepts of any function of the form y = f(x) is critical when graphing. A function can have one of two types of intercepts. They are known as the x and y intercepts. An intercept of a function is the point at which the function's graph intersects the axis. A graph's y intercept is the point at which the graph intersects the y-axis. We know that any point just on y-axis has an x-coordinate of 0. As a result, the x-coordinate of the a y-intercept is 0.For the given question;
The graph of the straight line is given.
The y-intercept of the line is the point on y axis where the value of the x becomes zero.
At x = 0, y = -2.
Thus, he y-intercept of the line on the graph is -2.
