What is stem-and-leaf plot?A stem-and-leaf plot is a table that is used to display numbers. It is similar to a histogram. A stem-and-leaf plot divides a number into a stem and a leaf. The stem is the first number in the digit while the leaf is the last number. For example in the number 21, 2 would be the stem and 1 would be the leaf.
An advantage of the stem-and-leaf plot is that all the data in the data set are shown. A drawback of a stem-and-leaf plot is that it can only be used for a small dataset.
Looking at the stem-and-leaf plot, it can be seen that the professors in their 40s have the highest frequency. They are 14 professors in their 40s.

d²y dx² A curve has an equation which satisfies curve, and the gradient of the curve at the point P is 9. Determine the equation of the curve. Working out: = 6x-4. The point P (2, 11) lies on the
The equation of the curve is [tex]y=x^{3}-2x^{2}+5x+1[/tex].
The Gradient of the curve at a point is defined as the gradient of the tangent to the curve at that point. To find the gradient at a particular point on the curve y=f(x), simply substitute the x -coordinate of that point into the derivative.
Given the gradient of a curve at a point P(2,11) is 9.
[tex]\frac{d^{2}y }{dx^{2} } =6x-4[/tex]
Integrating both sides-
[tex]\frac{dy}{dx } =\frac{6x^{2} }{2}-4x+C[/tex]
[tex]\frac{dy}{dx } =3x^{2} -4x+C[/tex]
Now, the gradient of a curve at a point P(2,11) is 9.
⇒[tex]3(2^{2})-4(2)+C=9[/tex]
⇒4+C=9
⇒C=5
So, [tex]\frac{dy}{dx } =3x^{2} -4x+5[/tex]
Again integrating both sides-
[tex]y=x^{3}-2x^{2} +5x+A[/tex]
Point(2,11) lies on the curve.
So, [tex]11=2^{3}-2(2^{2}) +5(2)+A[/tex]
⇒11=10+A
⇒A=1
Putting value of A in equation of curve-
[tex]y=x^{3}-2x^{2}+5x+1[/tex].
Thus, The equation of the curve is [tex]y=x^{3}-2x^{2}+5x+1[/tex].

It takes you 53 seconds to walk from the first (ground) floor of a building to the third floor. How long will it take you to walk from the first floor to the sixth floor (at the same pace, assuming all floors have the same height)?
The time taken to walk from first floor to sixth floor at same pace, assuming
all floors have the same height is 318 seconds or 5 minutes 18 seconds.
It takes you 53 seconds to walk from the first (ground) floor of a building to the third floor.
There are 60 seconds in every minute, so converting seconds to minutes is simple. Just divide the number of seconds by 60 to get your answer. Every 60 seconds a full minute has passed. Dividing a number tells you how many times one number "fits" in the other. Oftentimes the number of seconds will not perfectly convert into minutes. This decimal represents the number of seconds left over.
Walking one floor takes 53 seconds.
So, walking six floors at same pace = 53 seconds * 6
=> 318 seconds or 5 minutes 18 seconds.

A scale on a blue print drawing of a house shows that 6 centimeters represents 3 meters.
What number of centimeters on the blue print represents an actual distance of 27 meters?
The number of centimeters on the blue print is 54 cm.
Given the scale of the drawing of a blue house shows that 6 cm is 3 meters.
The plan says 6 cm is 3 meters. The equation can be written, like this:
6cm = 3m
However, it's not useful for a conversion, so it's better to write it as a ratio, like this:
6cm/ 3m or 3m / 6cm
This as a conversion, take the given number and multiply it by the appropriate conversion factor. The key to choosing the right one is to think about which units need to be destroyed and how to achieve this. In this problem we are given 27 meters and we want to know it will be centimeters on the scale. So we have to choose a conversion factor that will remove meters and leave us with centimeters. If in doubt, identify a possible problem and test the units.
Example: 27m × (3m / 6cm)
It is clear that in this form the counters will not be cancelled.
So instead we try:
27m × (6cm / 3m) = 162cm / 3 = 54cm

Round to one decimal place.
A

C

D
2.8
B
Answer: The length of AB is approximately 6.32 units.
Step-by-step explanation:
We have been given an image of a triangle on coordinate plane and we are asked to find the length of mid-segment MN and segment AB.
First of all, we will find the length of MN using distance formula.
What is the formula for length of a line?
When dealing with horizontal lines, the length of the line is simply the difference between the two points' x-coordinates. In a similar fashion, a vertical line's length can be found by subtracting one of the y-coordinates with the other.
d = [tex]\sqrt{{(x2 - x1)^{2} } + (y2 - y1 )^{2} }[/tex]
Let us assume option A is = (5.9 ; 2.8)
Where x1 = 5
x2 = 2
y1 = 9
y2 = 8
d = [tex]\sqrt{{(2-5)^{2} } + (8-9)^{2} }[/tex]
d = [tex]\sqrt[{-3^{2} } + -1^{2} ][/tex][tex]\sqrt{-3^{2} } + (-1)^{2}[/tex]
d = [tex]\sqrt{9+1}[/tex]
d = [tex]\sqrt{10}[/tex]
d = 3.1622
Therefore, the length of MN is approximately 3.1622 units.
We know that length of mid-segment connecting two sides of a triangle is half the length of third side of the triangle.
To find the length of AB, we will multiply length of mid-segment MN by 2.
Length of AB = 3.1622 X 2
Length of AB = 6.3244 ≅ 6.32
Therefore, the length of AB is approximately 6.32 units and (5.9 ; 2.8) is the correct choice.

The correct option is A. 0.156. The number (1.092×10¹) is 156 times larger than number (7×10⁻¹).
What is defined as the scientific notations?Scientific notation is a method of writing extremely large or extremely small numbers. Whenever a number among 1 and 10 is multiplied by a power of 10, it is written in scientific notation. 650,000,000, for example, can be composed in scientific notation as 6.5× 10⁸.Scientific notation is a method of writing extremely large or extremely small numbers in a way that makes them easier to read as well as work with. A number is expressed as the product of an amount that is equal to one but less than ten and an integral power of ten.For the given number;
The number 1.092×10¹ can be written as; 10.92 after multiplication with 10.
Similarly, the number 7×10⁻¹ can be written as 0.7 after diving with 10.
Now, divide larger number by 0.7
= 10.92/0.7
= 156
Thus, the number 1.092×10¹ is almost 156 time greater than (7×10⁻¹).

In a unit circle, 0 = 3pi/2. What is the terminal point?
O A. (1,0)
O B. (0,1)
O C. (0, -1)
O D. (-1,0)
Option c - (0 , -1).
Terminal Point on the Unit Circle. To find the terminal point on the unit circle, start at (1, 0), measure the angle in degree or radian on the circle (move counter clockwise if the angle is positive and clockwise if the angle is negative.) The coordinate of the endpoint is called the terminal point.
In a unit circle, θ = 3π/2 radians.
r = 1
Angle θ = 3π/2
The terminal point is (rcosθ, rsinθ)
= (cos3π/2, sin3π/2)
cos3π/2 = 0
sin3π/2 = -1
= (0, -1)
Thus, for the unit circle 3π/2 = 0 ,the terminal points are (0, -1) . So the option C is the correct answer.

how do i solve y=3(0)^3-2(0)^2+13
Answer:
y = 13
Step-by-step explanation:
You want to "solve" y=3(0)^3-2(0)^2+13.
EvaluationAn exponent signifies repeated multiplication. That is ...
(0)^3 = 0×0×0
Of course, anything times zero is zero, so the first and second terms are both zero:
3(0)³ -2(0)² = 0 -0 = 0
Adding 0 to 13 does not change its value.
y = 3(0³) -2(0²) +13 = 0 -0 +13
