What is the overlap of Data Set 1 and Data Set 2?
high
moderate
low
none
Answer: High
Step-by-step explanation: Same endpoints and similar values
The high overlap is the overlap that we are having here.
What is meant by high data set overlap?High dataset overlap typically refers to a situation in which two or more datasets contain many of the same or very similar entries or data points.
This can happen, for instance, in the field of machine learning, when training and testing datasets have high overlap, which could lead to overfitting. Overfitting is a modeling error that occurs when a function is too closely fit to a limited set of data points and may therefore perform poorly on new, unseen data.

The area of a square floor on a scale drawing is 100 square centimeters, and the scale drawing is 1 centimeter:2 ft. What is the area of the actual floor? What is the ratio of the area in the drawing to the actual area?
The area of the actual floor is ................... square feet.
The ratio of the area in the drawing to the actual area is 1 square centimeter:............. square ft
Answer: Ok let's say the area is 100 sq cm because it is 10x10 square. Now if 1 cm is 2 ft then 10 cm is 20 ft. So 20 x 20 is 400 sq ft which is the actual area.
1 sq cm = 4 sq ft

Dylan loves reading. He went to buy books from a bookstore. A school bag and 3 books cost $180. A school bag and 5 books cost $270. How much did each book cost?
School bag _ y
book _ x
system:
y+3x=180
y+5x=270
y=180-3x (and we put that instead of 'y' in the second equation)
(180-3x)+5x=270
180+2x=270
2x=90
x=45
so one book costs $45
and school bag:
y+3×45=180
y+135=180
y=180-135
y=45
Answer:
Each book costed 45$.
Step-by-step explanation:
Let x represent the price of a school bag and y represent the price of a book.
we get the following system of equations:
x+3y=180 (equation 1)
x+5y=270 (equation 2)
using equation 1: x=180-3y
then we substitute x in equation 2 in order to find y:
180-3y+5y=270
180+2y=270
2y=270-180=90
y=90/2=45
and we know that y represents the price of a book, so each book costs 45$.

Answer:
x = 30'
2x = 60'
3x = 90'
Step-by-step explanation:
2x + 3x + x = 180
6x = 180
6x ÷6 = 180 ÷ 6
x = 30'
therefore
2x = 60"
3x = 90'

55 deliveries in 11 hours = 5 deliveries in __hours
1 hour
Step-by-step explanation:To solve this problem, we will need to use the unitary method.
Determining the equation:
⇒ 55 deliveries in 11 hours
⇒ 55 deliveries = 11 hours
Finding how much hours in 5 deliveries:
Divide both sides by x:
⇒ 55 deliveries = 11 hours
⇒ 55/x deliveries = 11/x hours
Simplify the numerators:
⇒ 55/x deliveries = 11/x hours
⇒ 5/x deliveries = 1/x hours
Use cross multiplication:
⇒ 5x deliveries = x hours
Divide both sides by x:
⇒ 5x/x deliveries = x/x hours
⇒ 5 deliveries = 1 hour
Answer:
1 hour
Step-by-step explanation:
let x = unknown number of hours
Set up ratios of deliveries to hours
[tex]\sf \implies 55 : 11 = 5 : x[/tex]
[tex]\sf \implies \dfrac{55}{11}=\dfrac{5}{x}[/tex]
Cross multiply:
[tex]\sf \implies 55x=5 \cdot 11[/tex]
[tex]\sf \implies 55x=55[/tex]
Divide both sides by 55:
[tex]\sf \implies x=1[/tex]
Therefore, 55 deliveries in 11 hours = 5 deliveries in 1 hour
Write the equation for each translation of the graph of y=|x+2|.
a) one unit up
b) one unit down
c) one unit to the left
d) one unit to the right
a) one unit up = Ix + 2I + 1
b) one unit down = Ix + 2I - 1
c) one unit to the left = Ix + 1I
d) one unit to the right = Ix + 3I
What is transformation on the graphs?Let the function f(x) and g(x) are two real functions.
And g (x) = f (x) + k, where k is real numbers.
Function can be sketched by shifting f (x), k units vertically.
The direction of shift can be found by the value of k:
if k > 0, the base graph shifts k units up, and
if k < 0, the base graph shifts k units down.
The function provided by the basic function f(x) and the constant
g(x) = f(x - k),
may be drawn by horizontally moving the f(x) k unit coordinates.
The shift's direction depends on the value of k. Specifically,
The base graph moves k units to the right if k > 0, and
The base graph moves k units to the left if k < 0.
The graph of y = |x+2| is a V-shaped graph centered at x = -2.
To translate this graph, we need to modify the equation to shift it up/down or left/right.
Here are the equations for each translation:
a) To shift the graph one unit up, we need to add 1 to the equation:
y = |x+2| + 1
b) To shift the graph one unit down, we need to subtract 1 from the equation:
y = |x+2| - 1
c) To shift the graph one unit to the left, we need to replace x with (x+1) in the equation (since moving left means decreasing x by 1):
y = |(x+1)+2|
Simplifying this gives:
y = |x+3|
d) To shift the graph one unit to the right, we need to replace x with (x-1) in the equation (since moving right means increasing x by 1):
y = |(x-1)+2|
Simplifying this gives:
y = |x+1|
Therefore, all the required values are given above.

PLEASE HELP Jax is surveying the number of children in restaurants. One restaurant has 7 children and a total of 42 customers. The next restaurant has 60 customers. Based on his survey, how many can he predict will be children?
A. 25
B. 10
C. 360
D. 5
Answer:
B.10
Step-by-step explanation:
42÷7=1. 1 child for every 6 customer. 60÷6= 10
Answer:
B
Step-by-step explanation:
If the first restaurant had 7 children within 42 customers, then we can divide 42 by 7 to get 6, which means 1 in 6 customers are children. If we apply this to the next restaurant, we will divide 60 by 6 to get 10.
This means there are 10 children in the second restaurant, so the answer is B.

Also the diameter is 4 inches
Answer:
12.56 in²
Step-by-step explanation:
Area = πr²
Substitute for pi.
A = 3.14 × r²
The diameter is 4. We divide the diameter by 2 to get the radius.
4 ÷ 2 = 2
Substitute for the radius.
A = 3.14 × 2²

This figure consists of a rectangle and semicircle.
What is the area of this figure?
Use 3.14 for π.
A shape made up of a rectangle of the left and a semicircle on the right. The rectangle has a width of 15 meters and a height of 12 meters.
Enter your answer to the nearest hundredths place in the box.
Question 5 options:
Step-by-step explanation:
l = 12 metres
b = 15 metres
diameter of semicircle = length = 12 m
radius = 12/2 = 6 cm
area of the figure = area of rectangle + area of semi circle
= l × b + πr²
= 12 × 15 + 3.14 × 6²
= 180 + 113.04
= 293.04 m²
The perimeter of the figure is 60.84 meters.
What is a rectangle?A rectangle is a quadrilateral with all four interior angles 90°.
Given that, the width and height of the rectangle are 15 meters and 12 meters respectively.
Note that the diamter o he semicircel is 12 meters.
The radius of the semicircle is:
12/2
= 6 meters
The perimeter of the figure is given by:
15 + 12 + 15 + π(6)
= 42 + 3.14×6
= 60.84

Answer:
the cable is 2\sqrt{41} meters long
Step-by-step explanation:
after drawing out the lengths given, you can see that you need to find the hypotenuse of a triangle with legs 10 and 8 meters long.
10^2+8^2=164
sqrt of 164 is [tex]2\sqrt{41}[/tex]
Answer:
[tex]2\sqrt{41}\: \sf m[/tex] = 12.81 m (nearest hundredth)
Step-by-step explanation:
This can be modeled as a right triangle, with:
height = 10 ftbase = 8 ftThe length of the cable is the hypotenuse.
Using Pythagoras' Theorem: [tex]a^2+b^2=c^2[/tex]
(where a and b are the legs, and c is the hypotenuse, of a right triangle)
[tex]\implies 8^2+10^2=c^2[/tex]
[tex]\implies 164=c^2[/tex]
[tex]\implies c=\sqrt{164}[/tex]
[tex]\implies c=\sqrt{4 \cdot 41}[/tex]
[tex]\implies c=\sqrt{4} \sqrt{41}[/tex]
[tex]\implies c=2\sqrt{41}\: \sf m[/tex]
Therefore, the length of the cable is [tex]2\sqrt{41}\: \sf m[/tex] = 12.81 m (nearest hundredth)

Zach substitutes the values 32 inches, 20 inches and 20 inches into the Pythagorean theorem. Explain what Zach is most likely trying to find out.
Answer:if a triangle is a right triangle, then the sum of the squares of the lenghts of the legs is equal to the square of the length of the hypotenuse.
- a property of all triangles with a right-angle (an angle of 90°)
Step-by-step explanation:
Zach is trying to find out the hypotenuse value of the right-angle triangle.
What is the right triangle?A right triangle is defined as a triangle in which one angle is a right angle or two sides are perpendicular.
The Pythagorean theorem states that "in a right triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the lengths of the other two sides".
Zach is most likely trying to find the length of the hypotenuse of a right triangle, which is the side opposite the right angle, given the lengths of the other two sides.
In this case, given 32 inches, 20 inches, and 20 inches values, he's trying to find out the hypotenuse value of the right-angle triangle.
