Molly's family traveled 5/8 of the distance to her uncle's house on Saturday. They traveled 1/3 of the remaining distance on Sunday. What fraction of the total distance to her uncle's house was traveled on Sunday?

Standard Deviation of 7 is  2.983.

How to interpret  standard deviation?

The term "standard deviation" (or "") refers to the degree of dispersion of the data from the mean.

                    Data are grouped around the mean when the standard deviation is low, and are more dispersed when the standard deviation is high.

Describe standard deviation using an example.

Think about the following data: 2, 1, 3, 2, 4. The average and the sum of squares representing the observations' variances from the mean will be 2.4 and 5.2, respectively. This means that (5.2/5) = 1.01 will be the standard deviation.

       Mean = 7,

Standard Deviation of 7 =   2.983.

The equation is y = 1/3 x + 10/3. The y-intercept is 10/3.

An equation of the line is defined as a linear equation having a degree of one. The equation of the line contains two variables x and y. And the third parameter is the slope of the line which represents the elevation of the line.

The general form of the equation of the line:-

y = mx + c

m = slope

c = y-intercept

Slope = ( y₂ - y₁ ) / ( x₂ - x₁ )

Given that the point (5,5) is on a line with slope 1/3. The y-intercept will be calculated as,

y = mx + c

5 = (5/3)) + c

c = ( 15 - 5 ) / 3

Answer:

[x] is the greatest integer function, which returns the greatest integer less than or equal to x. This can be written as a piecewise linear function as follows:

f(x) =

x-1, if x is not an integer and x>1

x, if x is an integer or x<=1

For example, if x=6, then f(x)=6. If x=6.5, then f(x)=5. If x=0.5, then f(x)=0.

So, the piecewise linear function for f(x)=[x] is:

f(x) =

x-1, if x is not an integer and x>1

x, if x is an integer or x<=1

Step-by-step explanation:

always remember Pythagoras for right-angled triangles :

c² = a² + b²

c is the Hypotenuse (the side opposite of the 90° angle), a and b are the legs.

this principle must be always fulfilled, otherwise it is not a right-angled triangle.

when your have a triangle problem (particularly for a right-angled triangle) with only side information, there is a high chance that you need to use Pythagoras.

in our case

(2×sqrt(3))² = x² + (sqrt(3))²

4×3 = x² + 3

12 = x² + 3

x² = 9

x = 3

that's all.

FYI : sqrt(x²) has actually 2 solutions : -x and +x, as both are squared equal to x².

but a negative number does not make any sense for general side lengths and similar things. so, the positive solution here is the only valid one.

Answer:

  (i) height: 36.6 m

  (ii) BP = 36.6 m

  (iii) AB = 51.8 m

  (iv) AC = 73.2 m

Step-by-step explanation:

Given angles of elevation of 45° and 30° to the same point A from locations 100 m apart, you want to know the height of A, and distances BP, AB, and AC in the diagram.

The figure is divided into two special triangles. The one on the left is an isosceles right triangle with side lengths in the ratio 1:1:√2. The one on the right is a 30°-60°-90° triangle with side lengths in the ratio 1:√3:2. The common side AP corresponds to one ratio unit in each of these ratios.

BP = AP = 1 ratio unit means BP : PC = 1 : √3, and ...

  BP/BC = 1/(1+√3)

  BP = BC/(1+√3) ≈ (100 m)/2.73205

  BP ≈ 33.6 m

  AP = 33.6 m . . . . . . same as BP

AB is √2 times AP, so is ...

  AB = √2 · 36.6 m

  AB ≈ 51.8 m

AC is 2 times AP, so is ...

  AC = 2·(36.6 m)

  AC = 73.2 m

The remaining angles  ∠B ,∠C and ∠D is 90°,60°,90°.

Given : Angle A = 120°

To find: ∠B ,∠C , ∠D

Solution: In figure, an inscribed angle is the angle formed in the innards of a circle when two heartstrings cross on the circle. It can also be outlined as the angle subtended at a point on the circle by two presented junctures on the circle. Inversely, an incised angle is defined by two heartstrings of the circle sharing an endpoint .

∠A+∠C=180

 ∠C=180-120

 ∠C= 60;

 In triangle ABC :  ∠BAC + ∠ACB+∠ABC=180°

                               60° + 30° + ∠ABC = 180°

                                ∠ABC = 180°-90°

                                ∠ABC = 90° (so B is 90°)

Therefore, ∠B+∠D=180°

                   ∠D=180°-90°

                    ∠D=90°

Draw a line segment, place the compass point on point A, and draw an arc that intersects the line segment. Next, place the compass point on point B, and draw another arc that intersects the first arc at a point on the line segment. Finally, place the compass on the point where the two arcs intersect without changing the width of the second arc, and draw another arc that intersects the line segment. Finally, connect the point where the second arc intersects the segment to point C.

When two straight lines or rays intersect at a single endpoint, an angle is created. The vertex of an angle is the location where two points come together.

Angle measures are helpful not just for academic purposes but also for understanding and using the objects around us. They may aid with spatial knowledge and the link between numbers and measurements.

Follow these steps to draw angle ABC:

The base of the angle should be represented by a section of a line.

With the compass's point on point A, draw an arc that crosses the line segment.

Draw a second arc that crosses the previous arc at a point on the line segment by setting the compass's point on point B.

Place the compass on the intersection of the two arcs and create another arc that intersects the line segment without adjusting the compass's width.

To finish the angle, join point C to the location where the second arc crosses the line segment.

The number of two-points and three points shot the cruisers scored are 24 and 19 respectively.

The Cruisers scored a total of 105 points in a basketball game against the Strikers. The Cruisers had a total of 43 baskets, some of which were two-point shots and some of which were three-point shots.

Therefore, the number of two-points and three-points the cruiser scored is as follows:

let

x = number of two-points

y = number of three-points

Hence, using equation

x + y = 43

2x + 3y = 105

Multiply equation(i) by 2

2x + 2y = 86

2x + 3y = 105

subtract equation(i) from equation(ii)

y = 19

Let's find x as follows:

x = 43 - 19

x = 24

Step-by-step explanation:

With an increase of 79% the growth factor is 1.79.

The rate at which a quantity multiplies itself over time is known as its growth factor.

A quantity's growth rate is the factor by which it grows (or shrinks) over time.

An increase of 79% is the same result as multiplying with 1.79.

We call 1.79 a growth factor.

In other words:

With an increase of 79%,

you will get 100+ 79 = 179%.

The growth factor that corresponds with 179% = 179 : 100 = 1.79.

Written as a formula, it looks like this:

With an increase of p % the growth factor is

g = (100 + p) / 100

Simplifying,

g = 1 + p /100

g = 1 + 79/100

g = 1 + 0.79

g = 1.79.

Therefore, the growth factor is 1.79.

x=0, y=-4

Step-by-step explanation:

y=3x-4

2(3x-4)-6x=-8

6x-8-6x=-8

This equation expresses x as a function of y, meaning y is the input and x is the output. This inverse equation can be used to solve for x when given a value of y

x = (y - 1) / 16

In order to find the inverse of a given equation, we need to switch the x and y values and solve for the new x. To do this, we start by subtracting 1 from both sides of the equation to isolate the y variable. Then, we divide both sides of the equation by 16 to find the inverse equation, x = (y - 1) / 16. This equation expresses x as a function of y, meaning y is the input and x is the output. This inverse equation can be used to solve for x when given a value of y
