The freezing point is normally distributed with mean of 0 degrees celsius and a standard deviation of 1 degree celsius. The probability of getting a score between -1.5 and 2.5 is 0.9332.
To find the probability of getting a score between -1.5 and 2.5, we need to find the area under the normal distribution curve for this range using a z-score table.
First, we need to convert the range into standard units, which is done by subtracting the mean and dividing by the standard deviation:
z1 = ( -1.5 - 0 ) / 1 = -1.5
z2 = ( 2.5 - 0 ) / 1 = 2.5
Next, we look up the z-scores in a z-score table to find the area under the normal curve:
P(-1.5 < Z < 2.5) = 0.9332
This means that the probability of getting a score between -1.5 and 2.5 is 0.9332 or 93.32%.

K A can of beans has surface area 368 cm². Its height is 18 cm. What is the radius of the circular top? .... The radius of the circular top is 4.6 cm. (Do not round until the final answer. Then round to the nearest hundredth as needed.)
Answer: The surface area of a cylinder with height h and base with radius r can be calculated as:
A = 2πr^2 + 2πrh
We know the surface area (A) and the height (h) of the can of beans:
A = 368 cm²
h = 18 cm
We can substitute these values into the formula above and solve for r:
368 = 2πr^2 + 2πrh
368 = 2πr^2 + 2πr * 18
368 = 2πr^2 + 36πr
332 = 2πr^2 + 36πr
2πr^2 + 36πr - 332 = 0
We can use the quadratic formula to solve for r:
r = (-b ± √(b^2 - 4ac)) / 2a
where a = 2π, b = 36π, c = -332
r = (-36π ± √(36π^2 - 4 * 2π * -332)) / 2 * 2π
r = (-36π ± √(1296π^2 + 2664π)) / 4π
r = (-36π ± √(1296π^2 + 2664π)) / 4π
r = (-36π ± √(1296π^2 + 2664π)) / 4π
r = (-36π ± √(1656π)) / 4π
r = (-36π ± √(1656π)) / 4π
r = (-36π ± 40π^(1/2)) / 4π
There are two possible values for r, but only one will result in a positive value for r (the other will give a negative value). So we can use the positive value:
r = (-36π + 40π^(1/2)) / 4π
r = (40π^(1/2) - 36π) / 4π
r = (40π^(1/2) - 36π) / 4π
r = (40π^(1/2) - 36π) / 4π
r = (40 - 36π) / 4π
r = (40 - 36π) / 4π
We can approximate π as 3.14 to calculate the numerical value of r:
r = (40 - 36 * 3.14) / (4 * 3.14)
r = (40 - 113.04) / (4 * 3.14)
r = (40 - 113.04) / 12.56
r = (40 - 113.04) / 12.56
r = -73.04 / 12.56
r = -5.79
Since the radius must be positive, we reject this solution. The only valid solution is:
r = (40π^(1/2) - 36π) / 4π
r = (40π^(1/2) - 36π) / 4π
r = (6.32 - 36π) / 4π
r = (6.32 - 36 * 3.14) / (4 * 3.14)
r = (6.32 - 113.04) / 12.56
r = -106.72 / 12.56
r = -8.49
Since the radius must be positive, we reject this solution as well. There are no valid solutions for r, which means the original statement that "the radius of the circular top is 4.6 cm" is incorrect.
Step-by-step explanation:
The radius of the circular top is 4.6 cm.
What is surface area?
Surface area is total area on the surface of a three-dimensional shape.
The surface area of the can is made up of the sum of the areas of its top and bottom circular faces and its cylindrical side.
Let the radius of the circular top be "r".
The area of the circular top can be found using the formula:
A = πr^2
So, πr^2 = (1/2) * 368 cm²
r^2 = (368 / 2π) cm²
r = √(368 / 2π) cm
Using the value of π = 3.14, we get:
r = √(368 / (2 * 3.14)) cm
r = √(59.0079) cm
r = 4.6 cm
Therefore, The radius of the circular top is 4.6 cm.

Maliyah buys a bus ticket to New Orleans, her favorite city in America. The original price of $120 . She uses a coupon code to get a 20% discount off of the original price . She is then charged a 6% tax on the discounted price . What is the final cost for Maliyah's bus ticket
By using the unitary method, the final cost of Maliyah's bus ticket after the discount and tax was $101.76.
The unitary method involves dividing the original price by the percentage discount and then multiplying the result by the percentage tax to find the final cost.
First, we will find the discounted price of the bus ticket. To do this, we divide the original price of $120 by 100 and multiply by 20 to find the discount amount.
=> $120 / 100 * 20 = $24.
So, the discount amount is $24.
Next, we subtract the discount amount from the original price to find the discounted price.
=> $120 - $24 = $96.
So, the discounted price of the bus ticket is $96.
Finally, we multiply the discounted price by the percentage tax of 6% to find the final cost. To do this, we divide the 6% tax by 100 and multiply by the discounted price.
=> 6 / 100 * $96 = $5.76.
So, the final cost of the bus ticket is
=> $96 + $5.76 = $101.76.

what is the difference between a line spectrum and a continuous spectrum? provide an example of each.
A line spectrum refers to a type of spectrum where light is emitted at specific, discrete frequencies. A continuous spectrum, on the other hand, refers to a type of spectrum where light is emitted at all frequencies within a given range.
A line spectrum refers to a type of spectrum where light is emitted at specific, discrete frequencies. The light is emitted in a pattern of individual lines, hence the name "line spectrum." Hot gases or plasmas often produce this type of spectrum, and the lines represent specific energies of electrons in the gas.
An example of a line spectrum is the Hydrogen spectrum, which consists of a series of distinct lines of different colours that correspond to different energies of the electrons in a hydrogen atom.
A continuous spectrum, on the other hand, refers to a type of spectrum where light is emitted at all frequencies within a given range. The light is emitted in a smooth, continuous manner, hence the name "continuous spectrum." This type of spectrum is often produced by hot solid objects, such as the sun, and it represents a continuous range of energies.

what is wrong with the following statement: boolean y = 12.5;
Answer:
we can not assign a floating-point number to a boolean variable
Step-by-step explanation:
The statement "boolean y = 12.5;" is incorrect or "wrong" because it is attempting to assign a floating-point value (12.5) to a boolean data type, which is a type of data that can only represent two values: true or false.
A boolean data type is a fundamental data type in programming and is commonly used in logic and decision-making structures. It is used to represent conditions that are either true or false, and can be used to control program flow, make decisions, and perform logical operations.
In the statement "boolean y = 12.5;", the value 12.5 is a floating-point value, which is a type of data that represents a decimal number with a fractional component. However, a boolean data type is not capable of representing such values, and can only represent two states: true or false.
In programming, attempting to assign a value of the wrong data type to a variable is known as a "type error" or a "type mismatch." Type errors can cause programs to fail, produce unexpected results, or behave in unintended ways.
To fix the statement "boolean y = 12.5;", the data type of the variable "y" should be changed to a data type that can represent decimal values, such as a floating-point data type like "double" or "float." Alternatively, if the intent of the statement was to assign a boolean value to the variable, the value of 12.5 should be replaced with a boolean expression that evaluates to either true or false.
In summary, the statement "boolean y = 12.5;" is incorrect or "wrong" because it attempts to assign a floating-point value to a boolean data type, which is not a valid data type for the value being assigned. Type errors like this can cause programs to fail, produce unexpected results, or behave in unintended ways, and must be corrected to ensure proper program operation.

A gardener will use up to 250 square feet for planting flowers and vegetables. She wants the area used for vegetables to be at least twice the area used for flowers. Let x denote the area (in square feet) used for flowers. Let y denote the area (in square feet) used for vegetables. Shade the region corresponding to all values of x and y that satisfy these requirements.
Answer:
Step-by-step explanation:
We can start by setting up the following system of inequalities to represent the requirements given in the problem:
x + y ≤ 250 (the total area used should not exceed 250 square feet)
y ≥ 2x (the area used for vegetables should be at least twice the area used for flowers)
To graph these inequalities, we can first graph the boundary lines for each inequality:
x + y = 250 (the boundary line for the first inequality, with points (250, 0) and (0, 250))
y = 2x (the boundary line for the second inequality, with points (0, 0) and (125, 250))
Then, we can shade the region that satisfies both inequalities, which is the region below the line x + y = 250 and to the right of the line y = 2x:
|
250-|__________________________
| / |
| / |
| / |
| / |
| / |
| / |
| / |
| / |
| / |
| / |
|/________________________|
0 125 250
The shaded region represents all values of x and y that satisfy the requirements given in the problem, where x is the area used for flowers and y is the area used for vegetables. The x and y values in this region can vary, as long as the total area used is less than or equal to 250 square feet and the area used for vegetables is at least twice the area used for flowers.
Answer:
To plot the region that satisfies the requirements, we can start by setting up the inequalities:
y ≥ 2x (the area used for vegetables is at least twice the area used for flowers)
x + y ≤ 250 (the total area used for planting is at most 250 square feet)
We can plot these inequalities on a coordinate plane to find the shaded region:
First, plot the line y = 2x (Load failedboundary line for the first inequality). This line passes through the origin and has a slope of 2, so we can plot additional points using this information. For example, when x = 50, y = 100 (since 100 is twice 50).
So, the shaded region on the coordinate plane corresponds to all values of x and y that satisfy the given requirements.
You want to build a sand castle on the seashore that will last two days. What two things should you consider?
Answer: sand and water
Sand : The first and most important thing you need to know about sand is that you can't do a thing with it unless it's wet. Here's why: when you add water to grains of sand, the liquid forms "bridges" that connect the granules to one another. This is why damp sand sticks together, so you can shape and carve it.
Water : Use lots of water. Dry sand in its natural state is lazy stuff. It wants to lie down and spread out into all sorts of nooks and crannies. The good news is that as long as you keep gravity working for you, there is really no way to add too much water. Which brings us to our second rule.2 Let it drain. If you've ever tried to make the base of a sandcastle by filling a plastic bucket with wet sand and then trying to unmould it, you've seen how important this rule is. With no place for the excess water to drain off, the sand makes a sucking, sticking, vacuum seal with the plastic and it becomes difficult, if not impossible, to remove the bucket.This is why successful sand sculptors do not use plastic buckets or other closed moulds but build their shapes by stacking handfuls of wet sand or by tamping it down in a topless and bottomless form.
Answer:
Placement and shape/size
Step-by-step explanation:
Placement: if the castle is to stay up for two days, you need to take into consideration the tide, and how far up on the seashore it will get. You need to know for a fact the ocean will not touch it, because if it does, chances are it will dig away at the foundation, making it topple over. You also need to make it in a place That little to no people will be there, so that they will not knock it over.
Shape/size: again, if it is to stay up for two days, you need to also consider the other weather than may occur. You need a good foundation that will not topple over. You need it tall enough that if some sand blows away, it will not matter. If it rains, you should have enough sand there that it would stay, and/or have something covering it, protecting it.

So y = -1/8 x² - 2x -1
Absolute Value Function:
Right: y = x + 3
so y = (x+1) + 2
F(x) = -1/8x² - 2x -1 -8 ≤ x < -4
(x + 1) + 2 -4 < x < 4

Please leave an explanation to how you got your answer.
The candle that will burn out first is the yellow candle rather than the blue candle.
How long will it take for each candle to completely burn out?Blue candle:
1/4 inch per hour or 0.25 inches per hour
8 / 0.25 = 32 hours to completely burn out
Yellow candle:
1/2 inch per hour or 0.5 inches per hour
12 / 0.5 = 24 hours
What candle will burn out first?If the blue candle is lit 6 hours before the yellow candle then:
Blue candle: 32 - 6 = 26 hours left
Yellow candle: 24 hours left
This means the yellow candle will burn out first.

What is the Area and Perimeter? WILL MARK AS BRAINLIEST.
The area of the shape is x²+2x +1 and the perimeter is 4x +7
What is area and perimeter?The area is the region covered by shape or figure whereas perimeter is the distance covered by outer boundary of the shape. The unit of area is given by square unit or unit2 and unit of perimeter is same as the unit.
The area of the shape is :
The shape is sub divided into 4 with different areas x, x , x², and 1
Therefore the area of the shape = x²+x+x+1 = x²+2x+1
The perimeter is obtained by adding all the sides
x+x+x+x+1+1+1+1+1+1+1 = 4x+7
therefore the perimeter of the shape is 4x+ 7

Answer: x = 2, y = 5
Step-by-step explanation:
Step 1: Substitute y = -2x + 9. --> {2x + 9 = 4x - 3}
Step 2: Isolate x for the 2-sided equation. (x = 2) --> y = -2 · 2 + 9.
Step 3: Simplify. y = 5.
Hope this helped. :)
HELP!!!!! Solve for the value of q
Answer:
q = 4
Step-by-step explanation:
The three angles shown lie on the same straight and are adjacent to each other.
Adjacent angles on a linear segment are called supplementary angles and their sum adds up to 180°
Plugging in the expressions for the three angles we get:
(8q + 1) + 90 + 57 = 180
==> 8q + 1 + 90 + 67 = 180
==> 8q + 148 = 180
==> 8q = 180 - 148
==> 8q = 32
q = 32/8 = 4
what feature in tableau was used in the video above to help understand the interpretation of the large p-value of the variable spec.feats in the multiple linear regression model whose independent variables are size and spec.feats?
In the video, the presenter used Tableau to help interpret the large p-value of the variable spec. feats in the multiple linear regression model.
The presenter first used a scatter plot to visualize the relationship between size and spec. feats and included a regression line to represent the linear relationship between the two variables.
The presenter then used Tableau's Trend Lines tab to calculate the p-value of the spec. feats by providing the regression equation and data points.
This allowed the presenter to determine the p-value of the spec. feats were too large to be significant and thus concluded that spec. feats did not have a significant linear relationship with size.
