The value of √12 is equals to 3.46, and the number 4 is larger than the number 3.46.
What does "square root" mean?The square root of a number x in mathematics is a number y whose square (the result of multiplying the number by itself, or y y), equals x.The radicand is the expression (or number) whose square root is being considered.The phrase or number in this instance that appears under the radical sign is known as the radicand, and it is 9.Square roots of negative integers can be discussed in relation to complex numbers.In any circumstance where the idea of an object's "square" is stated, square roots can be considered more generally.These include, among other things, function spaces and square matrices.The value of √12 = 3.46, and the number 4 is larger than the number 3.46.
Therefore, 4 > √12.

Simplify the expression 36 + 63 ÷ 9.
The point N lies on the segment .
Find the coordinates of N so that is 1/3 of MP.
The coordinates of N so that MN is 1/3 of MP are:
(0,7/4)
In geometry line segment is a part of a line that is bounded by two end points, and contains every point on the that is between end points.
Given, coordinates of M(-3,-2)
and coordinates of P(9,13)
so we have,
x₁ = -3
y₁ = -2
x₂ = 9
y₂ = 13
Also we know that MN is 1/3 of MP
⇒ MN/MP = 1/3 = mn
here, m= 1 and n=3
Let the coordinates of N be (x,y)
Therefore,
(x,y) = (nx₁+mx₂)/(m+n) , (ny₁+my₂)/m+n
⇒ (x,y) = (3(-3)+1(9)/1+3) , (3(-2)+1(13)/1+3)
⇒ (x,y) = (-9+9/4) , (-6+13/4)
⇒ (x,y) = (0,7/4)
Thus the coordinates of N so that MN is 1/3 of MP is (0,7/4)

The sum of an infinite geometric series is twice its first term then the common ratio(r) be 1/2.
What is an infinite geometric series?An infinite geometric series is the outcome of an unlimited geometric sequence. This series wouldn't have a finish. It is possible to calculate the sum of all finite geometric series. The terms in the sequence will grow steadily larger, but adding the larger numbers together will not provide a solution if the common ratio of an infinite geometric series is greater than one.
Given: S = 2a₁
a₁ be the first term
r be the common ratio
Let the equation be S = a₁/1-r
2a₁ = a₁/1-r
substitute the values in the above equation, we get
2 = 1/1-r
2 - 2r = 1
2r = 1
The value of r = 1/2
Therefore, the common ratio(r) be 1/2.

Determine whether the quadrilateral can always, sometimes, or never be inscribed in a circle. Explain your reasoning.
parallelogram
A rectangle as the only parallelogram that can be inscribed in a circle.
What shapes can be inscribed in a circle?Every circle has an inscribed triangle with any three given angle measurements (summing to 180°, of course), and every triangle can be inscribed in any circle (which is called its circumscribed circle or circumcircle). Every triangle has an incircle, which is a circle that has been inscribed.
The only parallelogram that can be inscribed in a circle is a rectangle. Because every rectangle can be inscribed in a (unique circle), the important point is that the radius of the circle is R. (I think). One of the properties of a rectangle is that the diagonals bisect in the 'center,' which is also the center of the circumscribing circle.

Write an equation to solve each problem. The first stage of a rocket burns 28 s longer than the second stage. If the total burning time for both stages is 152s , how long does each stage burn?
Answer:
From the Soldier's point of view, the American Civil War was not a continuous battle. Instead, it was long monotonous marches and long residency in camps punctuated by the terror and chaos of combat. When winter set in and the campaigning season came to a close, most Soldiers counted on a long, cold stay in a winter camp. The four log cabins at the center of the Army Heritage Trail represent the types of buildings which Soldiers in both the Union and the Confederate Armies spent the long dreary months of winter. The cabins are modeled after images from the USAHEC collection, including the Army of the Potomac's winter camp at Brandy Station and the Confederate camp at Centerville
Select the correct answer.
The spread of data set X is greater than the spread of data set Y, and the data sets are normally distributed. Which statement is true?
OA The mean of data set XIs greater than the mean of data set Y.
OB. The median of data set X is less than the median of data set Y.
OC. The standard deviation of data set Xis greater than the standard deviation of data set Y.
OD. The range of data set X is less than the range of data set Y.
O E.
The mode of data set X is greater than the mode of data set Y.
Answer:
C
Step-by-step explanation:
Just the spread of normally distributed data tells us nothing about the mean, mode or median, so answers A, B, and E are out of question.
The range is based on the difference between the highest and lowest elements. As there can be big outliers, we have no idea if D is true, although we expect distributions with bigger spread to generally exhibit bigger ranges.
We're left with answer C. Standard deviation is a measure of "how much the data can deviate from the mean". It's also one of the measures of spread. We expect data that's more spread out (higher spread) to have a higher standard deviation.

You and your friend are swimming against the current. You move forward 15 feet. Your friend is not a strong swimmer, so he moves back 6 feet. write each amount as the distance swam.
The amount of you swam is +15 feet and your friend swam is -6 feet.
Given that you move forward 15 feet and your friend is not a strong swimmer, so he moves back 6 feet.
The arithmetic operators means performing an addition, subtraction, multiplication, division, exponentiation, and modulus operations.
It is given that you move the forward that means you move in positive direction.
So, you move forward means you move +15 feet.
It is also given that your friend is not a strong swimmer, so he moves back that means he move in negative direction.
So, your friend moves backward means he move -6 feet.
Hence, you move forward 15 feet is +15 feet and your friend is not a strong swimmer, so he moves back 6 feet is -6 feet.

Answer:
y = 2016 - 112x
Step-by-step explanation:
because he is paying 112 dollars each month for 18 months
y= 2016 -112x
for instance, he paid it for 6 months we would say
y = 2016 - 112(6)
y = 2016 - 672
y = 1334
so, y = 2016 - 112x
A 90 -inch board is cut into two pieces. One piece is two times the length of the other. Find the length of the shorter piece.
Answer:

Step-by-step explanation:
We know that the total length of the board is 90 inches and we know that the shorter piece is two times smaller than the other so we have two pieces divided into three sections 90 divided by three is 30 and since we realize that 30x2=60 and 60+30=90 it means the longer board is 60 inches and smaller one is 30 I hope this helps.

Total 10 252 30 700
Number of observation (n) = 4
So, b = 4(700) - (10)(252) / ( 120 - 10²)
= 2800-2520/20
= 280/20
= 14
b = 14
Now a= 252 - (14)10/ 4

So, The linear regression line is

Write each equation in slope-intercept form. Then find the slope and y -intercept of each line. - [ (1/2)x - y ] = 3/4
The slope is 1/2 and the y-intercept is 3/4 in the equation - [ (1/2)x - y ] = 3/4.
What is a slope of line?A line's steepness and direction are determined by the slope of the line. Without actually using a compass, determining a line's slope in a coordinate plane allows one to anticipate whether a line is parallel, perpendicular, or not.
The change in a line's y coordinate relative to its change in x coordinate is referred to as the line's slope. Δy is the net change in the y coordinate, while Δx is the net change in the x coordinate.
Therefore,
m = y₂-y₁/x₂-x₁ (where m denotes the slope) can be used to express how the y coordinate changes in relation to the x coordinate.
Be aware that tan ∅ = y/x
We also refer to this tan as the line's slope
We know that the equation for slope(m) and y - intercept(c) of a line is given by :
y = mx + c
Here given the equation - [ (1/2)x - y ] = 3/4, lets simplify
⇒ - [ (1/2)x - y ] = 3/4
⇒ -(1/2)x + y = 3/4
⇒ y = (1/2)x + 3/4
Hence, the slope is 1/2 and the y-intercept is 3/4 in the equation - [ (1/2)x - y ] = 3/4

3 cups of pasta = 3/4 cup of sauce
We need to make 3/4 cup of sauce as 1 cup of sauce.
Multiply 4/3 on both sides.
