The answer to the question probability of randomly selected person has a blood pressure of 182.6 mmHg is 0.0088.
What is standard deviation?
A measure of a group of values' variance or dispersion in statistics is called the standard deviation. When the standard deviation is low, the values are more likely to fall within a narrow range, also known as the expected value, whereas when the standard deviation is high, the values tend to be closer to the mean.
The lowercase Greek letter sigma, which stands for the population standard deviation, or the Latin letter s, which stands for the sample standard deviation, are most frequently used in mathematical equations and texts to represent standard deviation. Standard deviation is also sometimes referred to as SD.
The mean blood pressure for people in china is 128 mmHg.
The standard deviation of 23 mmHg.
For blood pressure of 182.6 mmHg
=p(x> 182.6)
=p(z> 182.6-128/23)
=p(z> 2.37)
=0.0088
Hence the probability of a randomly selected person has a blood pressure of 182.6 mmHg is 0.0088.

Describe a situation in which you can buy 9 T-shirts and 1 sweatshirt, but you cannot buy 3 T-shirts and 8 sweatshirts. Write and graph a system of linear inequalities that represents the situation.
A situation in which the person can afford 9 t-shirts and one 1-sweatshirts, but not 3 T-shirts and 8 sweatshirts are when the value of the gift card is $100 and the price of each t-shirt is $10.
What is inequality?The relation between two unequal expressions is defined as inequality.
Given that, the person can afford 9 T-shirts and 1 sweatshirt but not 3 t-shirts and 8 sweatshirts.
Let the value of the gift card be y.
Let the cost of one shirt and one sweatshirt be t and s respectively.
Then, the inequality for the condition that "the person can afford 9 T-shirts and 1 sweatshirt" is:
9t + s ≤ y
The inequality for the condition that " the person cannot afford 3 t-shirts and 8 sweatshirts" is:
3t + 8s > y
Now, let the person buys 1 sweatshirt in any situation, then from inequalities (1) and (2):
9t + 1 ≤ y
3t + 8 > y
Hence, the system of inequalities is:
9t + 1 ≤ y
3t + 8 > y
The graph of the inequalities is shown.
Let the value of the gift card be $100 and the price of each t-shirt is
t =$10, then
9(10) + 1 ≤ 100
91≤100, true
And,
3(10) + 8 > 100
38 > 100, false
Hence, a situation in which the person can afford 9 t-shirts and one 1-sweatshirts, but not 3 T-shirts and 8 sweatshirts are when the value of the gift card is $100 and the price of each t-shirt is $10.

The cylinder and the cone have the same volume. What is the height of the cone?
Answer: [tex]h = \frac{3}{4}y[/tex] is the cone's height.
==================================================
Work Shown:
Let's set up each volume equation.
[tex]\text{VL} = \text{volume of cylinder}\\\\\text{VL} = \pi*r^2*h\\\\\text{VL} = \pi*x^2*y\\\\[/tex]
[tex]\text{VC} = \text{volume of cone}\\\\\text{VC} = \frac{1}{3}*\pi*r^2*h\\\\\text{VC} = \frac{1}{3}*\pi*(2x)^2*h\\\\\text{VC} = \frac{4}{3}\pi x^2*h\\\\[/tex]
Then we're told that VL and VC are the same value. Let's equate the right hand sides and solve for h.
[tex]\text{VL} = \text{VC}\\\\\pi x^2y = \frac{4}{3}\pi x^2 h\\\\x^2y = \frac{4}{3}x^2 h\\\\3x^2y = 4x^2 h\\\\h = \frac{3x^2y}{4x^2}\\\\h = \frac{3y}{4}\\\\h = \frac{3}{4}y\\\\[/tex]
Answer:
3y
Step-by-step explanation:
[tex]\boxed{\begin{minipage}{4 cm}\underline{Volume of a cylinder}\\\\$V=\pi r^2 h$\\\\where:\\ \phantom{ww}$\bullet$ $(r)$ is the radius. \\ \phantom{ww}$\bullet$ $h$ is the height.\\\end{minipage}}[/tex] [tex]\boxed{\begin{minipage}{4 cm}\underline{Volume of a cone}\\\\$V=\dfrac{1}{3} \pi r^2 h$\\\\where:\\ \phantom{ww}$\bullet$ $(r)$ is the radius. \\ \phantom{ww}$\bullet$ $h$ is the height.\\\end{minipage}}[/tex]
Given dimensions of the cylinder:
r = xh = yTherefore, the equation for the volume of the cylinder is:
[tex]\implies V_{\sf cylinder}=\pi x^2y[/tex]
Given dimensions of the cone:
diameter of base = 2x ⇒ r = xh = ?Therefore, the equation for the volume of the cone is:
[tex]\implies V_{\sf cone}=\dfrac{1}{3} \pi x^2 h[/tex]
As the cylinder and the cone have the same volume, substitute the equation for the volume of the cylinder into the equation for the volume of the cone an solve for h:
[tex]\begin{aligned}V_{\sf cylinder}&=V_{\sf cone}\\\implies \pi x^2 y&=\dfrac{1}{3} \pi x^2 h\\y&=\dfrac{1}{3} h\\3y&=h\\h&=3y\end{aligned}[/tex]
Therefore, the height of the cone is 3y.
suppose you are using the inclusion-exclusion principle to compute the number of elements in the union of four sets. each set has 15 elements. the pair-wise intersections have 5 elements each. the three-way intersections have 2 elements each. there is only one element in the intersection of all four sets. what is the size of the union?
Answer:
2x
Step-by-step explanation:
The size of the union according to the given data is 37.
What is a set theory?The study of sets, which are collections of objects, is a topic covered by the mathematical field known as set theory. A set is a clearly defined group of unique items, sometimes referred to as its elements or members, in set theory.
Let's use the inclusion-exclusion principle to compute the number of elements in the union of four sets:
First, we add up the sizes of the individual sets:
4 x 15 = 60
Next, we subtract the sizes of the pair-wise intersections:
6 x 5 = 30
We have to multiply by 6 because there are 6 pairs of sets.
Now we need to add back the sizes of the three-way intersections:
4 x 2 = 8
We have to multiply by 4 because there are 4 triples of sets.
Finally, we need to subtract the size of the intersection of all four sets:
-1
Putting it all together, we have:
60 - 30 + 8 - 1 = 37
Therefore, the size of the union is 37.

What is the slope of the line y =- 3x?.
The slope of the line y = -3x is -3.
What is slope?The slope of a line is the measure of the steepness and the direction of the line. It is defined as the change in y coordinate with respect to the change in x coordinate of that line.
The net change in y coordinate is Δy, while the net change in the x coordinate is Δx. Then the slope
m = Δy/Δx = dy/dx
Here the line is y = -3x
Differentiating the equation of line with respect to x, we get
dy /dx = -3
⇒ dy /dx = m = -3.
Therefore, the slope of the line y = -3x was found to be -3.

The slope of the line is B.
What is slope of the line ?In mathematics, the slope of a line is the change in y-coordinate with respect to the change in x-coordinate.
The net change in the y coordinate is denoted by Δy and the net change in the x coordinate is denoted by Δx.
So the change in the y coordinate for a change in the x coordinate is:
The slope of a straight line can also be expressed as:
In general, the slope of a line is a measure of its steepness and direction. The slope of the line between two points (x1,y1) and (x2,y2) can be easily determined by finding the difference in the coordinates of the points.
CalculationIf the x-coordinate of each point on a line is 5 more than half the y-coordinate, then x= y2+5.
To find the slope of the line, solve for y and put the equation in slope-intercept form (y = mx + b, where m is the slope).
To do so, first subtract 5 from both sides, then multiply the entire equation by 2 to get y = 2x − 10.
The slope is 2.

The area of rectangle ABCD is 23.5 cm² with vertices A(-1,11) B( 7,9) C(10,13) and D(2,7).
Define area.The region that an object's shape defines as its area. The area of a figure or any other two-dimensional geometric shape in a plane is how much space it occupies. The area a rectangle occupies is the space it takes up inside the limitations of its four sides. The dimensions of a rectangle determine its area. In essence, the area of a rectangle is equal to the sum of its length and breadth.
Given,
A(-1,11) B( 7,9) C(10,13) and D(2,7)
Calculate the length of the sides using the distance formula:
AB = √(7+1)² + (9 - 11)²
AB = √8² + 2²
AB = √16 + 4
AB = √20
AB = 4.47
BC = √(10-7)² + (13-9)²
BC = √3² + 4²
BC = √9 + 16
BC = √25
BC = 5
For area of rectangle:
Length × Width
5 × 4.47
23.5
