New car prices to fall within is $18,300 - $41,900
Interval of prices would we expect at least 95% of new car prices to fall within Suppose that the average price for new cars has a mean of $30,100, a standard deviation of $5,600 and is normally distributed. Based on this information, the interval of prices that we would expect at least 95% of new car prices to fall within is $18,300 - $41,900.How to solve the problem? We know that the average price of new cars is $30,100 and the standard deviation is $5,600. The normal distribution has 95% of the data points within two standard deviations of the mean. Therefore, the interval of prices that we would expect at least 95% of new car prices to fall within is given by:Lower limit: $30,100 - 2 × $5,600 = $18,300Upper limit: $30,100 + 2 × $5,600 = $41,900Thus, the interval of prices that we would expect at least 95% of new car prices to fall within is $18,300 - $41,900.

according to the myplate analysis report, empty calories should exceed no more than 362 calories for someone like miya. how many empty calories did miya consume on this 1-day menu? a. 793.34 empty calories b. 693.74 empty calories c. 593.54 empty calories d. 352.74 empty calories
352.74 empty calories did miya consume on this 1-day menu.
Hence option d. 352.74 empty calories is correct.
According to the my plate analysis report, how many empty calories did Miya consume on this 1-day menu.
Empty calories refer to those calories that are devoid of any nutrient and provide only energy.
Miya's 1-day menu needs to be analyzed to determine the empty calories count.
The options provided are:
a. 793.34 empty calories
b. 693.74 empty calories
c. 593.54 empty calories
d. 352.74 empty calories.
Let us understand the concept of empty calories in detail.
Empty calories refer to the calories provided by foods that contain little to no nutrients, like vitamins and minerals. Common sources of empty calories are sugary snacks and alcohol.
Though these foods provide energy, they lack the essential vitamins, minerals, and fiber that the body requires for optimal health.
Therefore, empty calories should be limited in the diet.
To determine the empty calories consumed by Miya, we need to know the nutrient content of her 1-day menu.
Once the nutrient content is known, we can subtract the total calories from empty calories to determine the number of calories that are not empty.
Let us assume that Miya's total calorie intake for the day is 1500 calories. Out of this, the my plate analysis report says that empty calories should not exceed 362 calories.
Therefore, the non-empty calories will be: 1500 - 362 = 1138 calories
From this, we can determine the correct option.
Let us substitute the values given in the options :
a. 793.34 empty calories: 1500 - 793.34 = 706.66
non-empty calories, which is less than 1138.
Therefore, this option is incorrect.
b. 693.74 empty calories: 1500 - 693.74 = 806.26 non-empty calories, which is less than 1138.
Therefore, this option is incorrect.
c. 593.54 empty calories: 1500 - 593.54 = 906.46 non-empty calories, which is less than 1138.
Therefore, this option is incorrect.
d. 352.74 empty calories: 1500 - 352.74 = 1147.26 non-empty calories, which is greater than 1138.
Therefore, this option is the correct answer.
So, the number of empty calories consumed by Miya on this 1-day menu is 352.74 empty calories.

Small pizzas at Ponnie's Pizza are cut into 6 pieces. The circumference of a small pizza is 12π inches. A large pizza is cut into 8 pieces. The diameter of a large pizza is 16 inches.
Joannie eats 2 slices of a small pizza. Mark eats 5 slices of a large pizza.
How many times greater are the square inches of pizza that Mark ate than the square inches of pizza that Joannie ate?
Enter your answer, rounded to the nearest tenth, in the box.
Answer:
Mark ate 3.3 times the square inches of pizza than Joannie ate.
Step-by-step explanation:
Small pizzaThe formula for the circumference of a circle is C = 2πr (where r is the radius). If the circumference of a small pizza is 12π inches, then its radius is:
[tex]\implies \sf Radius_{small\;pizza}=\dfrac{circumference}{2\pi}=\dfrac{12\pi}{2\pi}=6\;inches[/tex]
The formula for the area of a circle is A = πr² (where r is the radius).
Therefore, the area of a small pizza is:
[tex]\implies \sf Area_{small\;pizza}=\pi \cdot 6^2=36\pi \; in^2[/tex]
If the small pizzas are cut into 6 congruent pieces, the area of one slice of small pizza is:
[tex]\begin{aligned}\implies \sf Area_{small\;slice}&=\sf \dfrac{Area_{small\;pizza}}{6}\\\\&=\dfrac{36 \pi}{6}\\\\&=6 \pi \; \sf in^2\end{aligned}[/tex]
Therefore, the area of one slice of small pizza is 6π square inches.
[tex]\hrulefill[/tex]
Large pizzaThe diameter of a circle is twice its radius.
If the diameter of a large pizza is 16 inches then its radius is:
[tex]\implies \sf Radius_{large\;pizza}=\dfrac{diameter}{2}=\dfrac{16}{2}=8\;inches[/tex]
The formula for the area of a circle is A = πr² (where r is the radius).
Therefore, the area of a large pizza is:
[tex]\implies \sf Area_{large\;pizza}=\pi \cdot 8^2=64 \pi \; in^2[/tex]
If the large pizzas are cut into 8 congruent pieces, the area of one slice of large pizza is:
[tex]\begin{aligned}\implies \sf Area_{large\;slice}&=\sf \dfrac{Area_{large\;pizza}}{8}\\\\&=\dfrac{64 \pi}{8}\\\\&=8 \pi \; \sf in^2\end{aligned}[/tex]
Therefore, the area of one slice of large pizza is 8π square inches.
[tex]\hrulefill[/tex]
If Joannie eats 2 slices of small pizza, the square inches of pizza she ate is:
[tex]\implies \sf Joannie=2 \times 6 \pi = 12 \pi\;in^2[/tex]
If Mark eats 5 slices of large pizza, the square inches of pizza he ate is:
[tex]\implies \sf Mark =5 \times 8 \pi = 40\pi\;in^2[/tex]
To calculate how many times greater are the square inches of pizza that Mark ate than the square inches of pizza that Joannie ate, divide the area Mark ate by the area Joannie ate:
[tex]\implies \sf \dfrac{40 \pi}{12 \pi} = \dfrac{10}{3}=3.3\;(nearest\;tenth)[/tex]
Therefore, Mark ate 3.3 times the square inches of pizza than Joannie ate.
matrix flipped 3 coins. what is the probability that all three coins will land on the same side
Answer:
When flipping a coin, there are two possible outcomes: heads or tails. The probability of getting heads on any one flip is 1/2, and the probability of getting tails is also 1/2.
To find the probability that all three coins will land on the same side (either all heads or all tails), we can use the multiplication rule of probability, which states that the probability of two independent events occurring together is the product of their individual probabilities.
So, for each coin flip, there are two possible outcomes, and the probability of getting either outcome is 1/2. To find the probability that all three coins will land on the same side, we need to find the probability of getting either all heads or all tails.
The probability of getting all heads is:
(1/2) x (1/2) x (1/2) = 1/8
Similarly, the probability of getting all tails is also 1/8.
So, the probability of all three coins landing on the same side is:
1/8 + 1/8 = 2/8 = 1/4
Therefore, the probability that Matrix will flip 3 coins and all three coins will land on the same side is 1/8 or 0.125, which can also be written as a fraction or percentage.
Part 1: Use the picture below to find the ratio for each given the trig. function.
The value of the trigonometric function for the given ratio are Sin X= 12/20. Cos L = 16/34. Tan X = 12/16. Tan Z = 16/12. Tan L = 30/16. Cos M = 16/34.
What are trigonometric functions?The fundamental six functions of trigonometry have a range of numbers as their result and a domain input value that is the angle of a right triangle. The ratio of sides of a right-angled triangle is the basis for trigonometric functions and identities. Using trigonometric formulae, the sine, cosine, tangent, secant, and cotangent values are calculated for the perpendicular side, hypotenuse, and base of a right triangle.
Using the relationship of a right triangle and different trigonometric identities we have the values of the following as:
Sin X= opposite side to X / Hypotenuse = 12/20.
Cos L = adjacent side to L / Hypotenuse = 16/34.
Tan X = Opposite side to X / adjacent side to X = 12/16.
Tan Z = Opposite side to Z / adjacent side to Z = 16/12.
Tan L = 30/16.
Cos M = 16/34.
Hence, the value of the trigonometric function for the given ratio are Sin X= 12/20. Cos L = 16/34. Tan X = 12/16. Tan Z = 16/12. Tan L = 30/16. Cos M = 16/34.

Write the equation of a line parrallel to y=1/3x+4 and goes through -6,1
The equation of the line parallel to y = (1/3)x + 4 and passing through (-6, 1) is y = (1/3)x + 3.
To find the equation of a line parallel to y = (1/3)x + 4 and pass through the point (-6, 1), we can use the fact that parallel lines have the same slope. The slope of the given line is 1/3, so the slope of the parallel line must also be 1/3.
Now we have the slope (m = 1/3) and a point on the line (-6, 1), so we can use the point-slope form of the equation of a line:
y - y1 = m(x - x1)
Plugging in the values, we get:
y - 1 = (1/3)(x - (-6))
Simplifying, we get:
y - 1 = (1/3)x + 2
Adding 1 to both sides, we get the final equation:

Amazon uses a box where the volume can be represented by the expression x^3-2x^2-15x. What are the possible dimensions of the box?
Answer:
See below.
Step-by-step explanation:
The volume of the box is given by the expression.
V(x) = x^3 - 2x^2 - 15x
To find the possible dimensions of the box, we need to solve for the values of x that make the volume positive. A box with negative volume is not physically meaningful.
Setting V(x) > 0, we get.
x^3 - 2x^2 - 15x > 0
Factorizing the left-hand side, we get.
x(x^2 - 2x - 15) > 0
Now, we can find the values of x that make each factor positive.
For x > 0, both factors are positive.
For x^2 - 2x - 15 > 0, we can factor it as (x - 5)(x + 3) > 0. This inequality is true when x < -3 or x > 5.
Therefore, the possible dimensions of the box are.
x > 0 and x < -3, or
x > 0 and x > 5.
However, we need to remember that the dimensions of a physical box must be positive. Therefore, the only valid solution is,
x > 0 and x > 5.
So the possible dimensions of the box are.

using a single composite transformation matrix for k transformations of n points, what is the required number of multiplications?
The required number of multiplications using a single composite transformation matrix for k transformations of n points is n × k.
In computer graphics, composite transformation matrices are used to transform points and shapes. These matrices are created by combining multiple transformations into a single matrix, allowing for efficient processing of large amounts of data. The number of multiplications required to perform a composite transformation depends on the number of points being transformed and the number of transformations being applied.
If there are n points and k transformations, then the required number of multiplications is n × k.
This is because each point needs to be multiplied by the composite transformation matrix k times.
Therefore, the total number of multiplications is n × k.

Step-by-step explanation:
batman is taking a midnight stroll through gotham and sees the bat signal in the sky . if batman is 320 feet from the foot of the bat signal and the angle of elevation is 42* , find the height of the bat signal?
The height of the bat signal is about 214.12 feet.
Finding the Height of the Bat Signal from Batman's PositionTo find the height of the bat signal from Batman's position, we can use trigonometry.
The angle of elevation is the angle between the line of sight and the horizontal plane.
Using sine, we can set up the following equation:
sin(42) = height / 320
Solving for the height, we get:
height = 320 * sin(42)
Using a calculator, we can calculate the height to be approximately 214.12 feet.
Therefore, the height of the bat signal is about 214.12 feet.

ezra is redrawing the blueprint shown of a stage he is planning to build for his band. by what percentage should he multiply the dimensions of the stage so that the dimensions of the image are 12 the size of the original blueprint? what will be the perimeter of the updated blueprint?
The perimeter of the updated blueprint will be 24 times the sum of the original length and width.
If Ezra wants to multiply the dimensions of the stage by a certain percentage to make the image 12 times larger than the original, he needs to find out what percentage that is.
To do this, he can divide the desired size of the new stage by the original size of the stage, and then multiply by 100 to get the percentage increase. So, if the original blueprint dimensions are x by y, and he wants to make the image 12 times larger, the new dimensions will be 12x by 12y.
To find the percentage increase, he can use the following formula:
Percentage increase = [(new size - original size) / original size] x 100
In this case, the new size is 12 times the original size, so the formula becomes:
Percentage increase = [(12x * 12y - x * y) / (x * y)] x 100
Simplifying this expression gives:
Percentage increase = [(144xy - x * y) / (x * y)] x 100 = 14300%
Therefore, Ezra needs to multiply the dimensions of the stage by 14300% to make the image 12 times larger than the original blueprint.
To find the perimeter of the updated blueprint, he can use the formula for the perimeter of a rectangle, which is: Perimeter = 2(length + width)
In this case, the length and width have been multiplied by 12, so the new perimeter becomes:
Perimeter = 2(12x + 12y) = 24(x + y)
Therefore, the perimeter of the updated blueprint will be 24 times the sum of the original length and width.

Equation C is an example of Distributive Property of Multiplication over Addition. It can be used
when you multiply a number by a sum. According to this property, you can add the numbers
and then multiply by 8 or you can first multiply each addend by 3. (This is called distributing
the 3. ) Then, you can add the products. C. 8x (3 + 4) = (8x 3) + (8x 4)
8x7= 24 + 32
2x (5+ 6) = (2x 5) + (2x 6)
Simplified form of the expression 8 ( 3 + 4 ) using the Distributive Property of Multiplication over Addition is 56
To apply the Distributive Property of Multiplication over Addition, you need to multiply the number outside the parentheses by each term inside the parentheses and then add the products together.
In this case, the number outside the parentheses is 8, and the terms inside the parentheses are 3 and 4. So, you can apply the distributive property as follows:
8 ( 3 + 4 ) = 8 × 3 + 8 × 4
Multiply the numbers
= 24 + 32
Add the numbers
= 56
