mario's weekly poker winnings have a mean of 323 dollars and a standard deviation of 50 dollars . last week he won 177 dollars. how many standard deviations from the mean is that?
Answers
Therefore, Mario's winnings of 177 dollars is approximately 2.92 standard deviations below the mean.
We can calculate the number of standard deviations that Mario's winnings of 177 dollars is from the mean using the formula:
z = (x - μ) / σ
where x is the value we want to convert to standard deviations, μ is the mean of the distribution, and σ is the standard deviation of the distribution.
In this case, Mario's winnings of 177 dollars is the value we want to convert to standard deviations, the mean is μ = 323 dollars, and the standard deviation is σ = 50 dollars. Substituting these values into the formula, we get:
z = (177 - 323) / 50
= -2.92

Answers
The mean and the standard deviation of the sampling distribution of the sample mean is equal to 4.57 and 0.69 respectively.
Population mean 'μ' = 4.57
Sample size 'n' = 7
Population Standard deviation 'σ' =1.82
Mean of the sampling distribution of the sample mean is equal to the population mean,
which is μ = 4.57.
So, μₓ = μ = 4.57.
Standard deviation of the sampling distribution of the sample mean also known as the standard error of the mean.
Using the formula we have,
σₓ = σ / √(n)
Substituting the given values, we have,
⇒ σₓ = 1.82 / √(7)
⇒ σₓ = 1.82 / 2.646
⇒ σₓ = 0.6878
⇒ σₓ ≈ 0.69
This implies,
The standard deviation of the sampling distribution of the sample mean is σₓ ≈ 0.69.
Therefore, the mean of the sampling distribution of the sample mean and
standard deviation of the sampling distribution of the sample mean is equal to 4.57 and 0.69 respectively.

Pentagon, a=21.2 cm, s=30.8 cm
Answers
The area of regular pentagon with apothem 21.2 cm and side 30.8 cm is given by 1632.4 square cm.
We know that the area of a regular polygon with 'n' sides which has apothem of 'a' and side of length 's' is given by,
A = (n/2)*s*a
Here given regular polygon is a pentagon.
So the number of sides (n) = 5
Given that the length of each side of pentagon = 30.8 cm
so, s = 30.8 cm
The length of apothem is = 21.2 cm
So, a = 21.2 cm
So the area of the pentagon = (5/2)*21.2*30.8 = 1632.4 square cm.
Hence the area of the regular pentagon is 1632.4 square cm.

During the launch of a new book the publisher gave away 30 copies of the book as complementary copies to the VIPs who were present at the launch and sold the remaining at a cost of rupees 500 each. If the total collection on that day was rupees 7,35,000, find the total number of books given out on that day
Answers
The total number of books at the cost of Rupees 500 given out on that day is equal to 1,470
Cost of each copy of the book = Rupees 500
Total collection of the day = Rupees 7,35,000
Let us consider the total number of books printed for the launch is x.
Out of these x books 30 were given as complementary copies to VIPs .
And the remaining were sold at a cost of Rs. 500 each.
So, the total amount collected from selling the books is,
Amount collected from selling = (x - 30) × 500
Amount collected from selling + Amount collected from complementary copies = Total collection
Substituting the given values, we get,
⇒(x - 30) × 500 + 30 × 0 = 7,35,000
Simplifying the equation, we get,
⇒ 500x - 15,000 = 7,35,000
⇒ 500x = 7,50,000
⇒ x = 1,500
Total number of books printed for the launch was 1,500.
Out of these, 30 were given as complementary copies.
Number of books sold = 1,500 - 30 = 1,470
Therefore, the total number of books given out on that day excluding complementary copies was 1,470.

Solve the quadratic equation using the completing the square method
x^2 + 14x = -13
Answers
Answer:
The correct answer is x = -7 and x = 1. To solve this equation using the completing the square method, we first need to subtract 13 from both sides of the equation. We then need to add 49/4 to both sides of the equation. This gives us (x + 7/2)^2 = 49/4. We then take the square root of both sides of the equation to get x + 7/2 = 7/2 or x = -7. We can then solve for the other value of x by subtracting 7/2 from both sides of the equation, giving us x = 1.

Whoever can give me the surface area will get brainliest
Answers
Answer:
112ft
Step-by-step explanation:
To find the total surface area, we need to find the area of each face of the shape and add those area together.
So, for the rectangular faces, we multiply 4 by 8 to get 32.
For the triangle faces, we multiply 4 by 4 and divided by 2 which is 8. We can use the equation base*height/2 because the 4ft lengths form a right angle, meaning four is the base and height.
There are three rectangular faces, and two triangular faces, so
(3*32)+(2*8)= 112 ft

The width of the rectangle is 0.9 cm to 1 d.p.
What is triangle?A triangle is a three-sided polygon or a three-dimensional object composed of three flat surfaces that intersect at three vertices. Triangles can be classified based on their sides and angles. Equilateral triangles have all three sides equal, isosceles triangles have two sides equal, and scalene triangles have all three sides of different lengths. Triangles can also be classified based on their angles. Right triangles have one 90-degree angle, obtuse triangles have one angle greater than 90-degrees, and acute triangles have all angles less than 90-degrees.
The circumference of the shaded face can be calculated using the formula for circumference of a circle, C = 2πr, where r is the radius of the circle. The radius of the shaded face can be found by subtracting the height of the net (h) from the radius of the cylinder (R). Therefore, the circumference of the shaded face can be calculated as follows:
C = 2π(R-h)
= 2π(2-1)
= 2π
= 6.28
The circumference of the shaded face is 6.28 cm to 1 d.p.
b) To calculate the width, w, of the rectangle, we can use the formula for area of a rectangle, A = lw, where l is the length of the rectangle. The area of the rectangle can be found by adding the area of the two semicircles (πr2) and subtracting the area of the triangular part (½bh). Therefore, the width of the rectangle can be calculated as follows:
A = lw
w = A/l

Answers
A negative skewed distribution is a distribution where the majority of the data is on the higher end of the scale, with a few extreme low values that drag the tail of the distribution to the left.
A negative skewed distribution, also known as left-skewed, has a longer tail on the left side of the distribution, indicating that there are more values on the lower end of the scale. On the other hand, a positive skewed distribution, or right-skewed, has a longer tail on the right side, indicating more values on the higher end of the scale.
In a negative skewed distribution:
1. Draw a curve that starts high on the left side and gradually slopes down to the right with a long tail on the left side.
2. The mean is located to the left of the median.
In a positive skewed distribution:
1. Draw a curve that starts low on the left side and gradually slopes up to the right with a long tail on the right side.
2. The mean is located to the right of the median.

Lillian is building a walkway with a width of x feet to go around a swimming pool that measures 20 feet by 10 feet. If the total area of the pool and the walkway will be 816 square feet, how wide should the walkway be?
Answers
It is advisable that Lillian should build a walkway that is 7 feet wide.
Width calculation.
The Area of the pool is given by = 20 feet x 10 feet = 200 square feet
Therefore, total area of the pool and the walkway is given as 816 square feet. We can represent the width of the walkway by x feet.
The Length = 20 + 2x feet
the Width = 10 + 2x feet
so the area of the whole area, plus the walkway, is:
Area of the whole area = (20 + 2x) feet x (10 + 2x) feet = 200 + 40x + 4x^2 square feet
The total area of the pool and the walkway is given by 816 square feet,
Therefore, 200 + 40x + 4x^2 = 816
Simplify the equation, we get:
Then, 4x^2 + 40x - 616 = 0
Divide both sides by 4, we
=x^2 + 10x - 154 = 0
let solve for x by using the quadratic formula:
x = (-b ± (b^2 - 4ac)) / 2a
a = 1, b = 10, and c = -154. substitutes the values, we get:
which is x = (-10 ± sqrt(10^2 - 4(1)(-154))) / 2(1) = (-10 ± 24) / 2
Therefore, x = 7 or x = -17. let just ignore the negative, so the width of the walkway should be 7 feet.

So, 4/7 + (-5/7) = (4 - 5)/7 = -1/7.
Therefore, the sum of 4/7 and -5/7 is -1/7. This means that if we have a group of objects that we divide into 7 equal parts, we would have 4 of those parts in one group, and then we would take away 5 of those parts, leaving us with a negative part, or -1/7 of the whole group.

jayla bought the ingredients to make chicken soup, and wanted to make a double batch, which would be 12 cups of soup. a quick search told her that this was 173.3 cubic inches. she hoped the soup pot below would be big enough. the soup pot is 8 inches tall with a radius of 3 inches. what is the volume of the soup pot? answer choices are rounded to the nearest whole cubic inch.
Answers
The volume with the amount of soup that Jayla wants to make, which is 173.3 cubic inches.
In this problem, we are given the dimensions of the soup pot - a height of 8 inches and a radius of 3 inches. To find the volume of the soup pot, we will use the formula for the volume of a cylinder, which is:
V = πr²h
where V represents volume, π is a mathematical constant approximately equal to 3.14, r is the radius of the cylinder, and h is the height of the cylinder.
Substituting the given values into the formula, we get:
V = π(3)²(8) V = 72π
Now, we can use an approximation for π, such as 3.14, to get a numerical value:
V ≈ 226.19
Rounding to the nearest whole cubic inch, the volume of the soup pot is approximately 226 cubic inches.
