Answer:
3 1/3 signs
Step-by-step explanation:
A construction company is setting up signs on 2 1/2 miles of road the company places a sign every 3/4 of a mile which model represents How many signs the company will place on the road ?
From the above question:
3/4 miles = 1 sign
2 1/2 miles = x
Cross Multiply
3/4 miles × x = 2 1/2 miles × 1
x = 2 1/2 miles × 1/3/4 miles
x = 5/2 miles ÷ 3/4 miles
x = 5/2 miles × 4/3 miles
x = 10/3 signs
x = 3 1/3 signs
Therefore, the company will place 3 1/3 signs on the road.

The width of a rectangle is 4 x 3 y feet and the length of the rectangle is 9 x y 5 feet. Which expression represents the area of the rectangle in square feet?
Answer:
I dont know this in only good a t maths
The expression which represents the area of the rectangle in square feet is,
⇒ 36x⁴y⁶ feet square
What is mean by Rectangle?A rectangle is a two dimension figure with 4 sides, 4 corners and 4 right angles. The opposite sides of the rectangle are equal and parallel to each other.
Given that;
Width of a rectangle = 4x³y feet
Length of the rectangle = 9xy⁵ feet
We know that;
Area of the rectangle = Length x Width
Substitute all the values, we get;
Area of the rectangle = (4x³y) × (9xy⁵)
Area of the rectangle = 36x⁴y⁶ feet square

If a number is added to a set that is far away from the mean, how does this affect standard deviation?
Adding a number to the set such that the number is further away from the mean, will increase the SD. This is because the average distance of the numbers from the mean increases.
The Standard Deviation will increase if a new number is added to the collection that deviates more from the mean. This is due to an increase in the standard deviation of the numbers.
How the standard deviation is affected if a number is added to a set that is far away from the mean?The standard deviation demonstrates how widely things vary or diverge from the mean (mean, or expected value).
The Standard Deviation will vary if all terms in the set are multiplied or divided by the same number. The Standard Deviation will vary by the same amount.
The same number will likewise be changed for the mean. Imagine an animated, proportionate size growth for the spatter. There will be a change in the "measure of spread". The distance between each term and the mean doubles if every term is doubled, but the distance between each term also doubles, increasing the standard deviation. The Standard Deviation gets smaller if each word is divided by two.
In general, the Standard Deviation is decreased when a new number is added to the set that is extremely close to the mean. Visualize the paint spatter on the wall. Would the dispersion be more or smaller if we paint a droplet extremely near the center? – decrease because there are now relative to before more droplets at the center.

the angle of a quadrilateral are in the ratio 1 : 2 :3 :4 if the sum of the angles of a quadrilateral is 360 degree find the measure of each angle
Answer:
Step-by-step explanation:
Let the angles of quadrilateral be
x, 2x, 3x , 4x
sum of all angles of quadrilateral = 360°
x + 2x + 3x + 4x = 360°
10x = 360°
x = 360/10 = 36°
Ans. the four angles are :-
x = 36°
2x = 2 × 36 = 72°
3x = 3 × 36 = 108°
4x = 4 × 36 = 144°
Answer:
Step-by-step explanation:
Let the angles of quadrilateral be
x, 2x, 3x , 4x
sum of all angles of quadrilateral = 360°
x + 2x + 3x + 4x = 360°
10x = 360°
x = 360/10 = 36°
Ans. the four angles are :-
x = 36°
2x = 2 × 36 = 72°
3x = 3 × 36 = 108°
4x = 4 × 36 = 144°

Answer:
No
Step-by-step explanation:
(4, 10)
y ≤ 2x + 1
To determine if (4, 10) is a solution to the inequality, we want to plug in the given values.
10 ≤ 2(4) + 1
[multiply] 10 ≤ 8 + 1
[add] 10 ≤ 9
Determine if this statement is true.
10 is greater than 9; therefore (4, 10) is not a solution to this inequality.
Hope this helps!
Answer:
No
Step-by-step explanation:
If you plug in 10 for y and 4 for x, you will get 10 ≤ 9 which is false.
