Vector d is shown on a centimetre grid. Image attached.
Will mark brainliest to first correct answer.
Answer:
see explanation
Step-by-step explanation:
A column vector has the form [tex]\left[\begin{array}{ccc}x\\y\\\end{array}\right][/tex]
Following the direction of the arrow , the x- displacement = - 3 and y- displacement = 2 , then column vector is
[tex]\left[\begin{array}{ccc}-3\\2\\\end{array}\right][/tex]
h + k
= [tex]\left[\begin{array}{ccc}4\\-3\\\end{array}\right][/tex] + [tex]\left[\begin{array}{ccc}-2\\-1\\\end{array}\right][/tex] ← add corresponding elements from each vector
= [tex]\left[\begin{array}{ccc}4-2\\-3-1\\\end{array}\right][/tex]
= [tex]\left[\begin{array}{ccc}2\\-4\\\end{array}\right][/tex]

You have a bag that contains 6 red marbles and 3 blue marbles. You randomly choose one of the marbles. Without replacing the first marble, you choose a second marble. Find the probability of the events.
Answer:
12/27
Step-by-step explanation:
You have a bag that contains 6 red marbles and 3 blue marbles. You randomly choose one of the marbles. Without replacing the first marble, you choose a second marble. Find the probability of the events.
Let the total number of marbles = 6 red marble + 3 blue marbles = 9 marbles
You randomly choose one of the marbles. Without replacing the first marble, you choose a second marble. Find the probability of the events.
Assume all you picked is red( without replacement)
= 6/9 × 5/9
= 30/81
= 10/27
Assume all you picked is blue( without replacement)
= 3/9 × 2/9
= 6/81
= 2/27
The probability of the events is calculated as:
All red or All blue
= 10/27 + 2/27
= 12/27

Answer:
m=3.5h
Step-by-step explanation:
Just by looking at this, you know that it won't be either of the adding equations because it only works for the bottom input and output. So, we'll just look at the multiplying ones.
We know that multiplying should get us a bigger number (unless it's a fraction), so the equation h=3.5m won't work very well with this because h would be getting smaller not bigger.
That leaves us with m=3.5h.
To check this, I'll multiply 3.5 by 4 to see if it equals what m is on the table. Sure enough, it's 14. This also works with 2.5 and 8.75.
Find the value of if the perimeter of the rectangle is 30inches. The length is 2x + 3and the width is x
Answer:
The perimeter of a rectangle is 30 meters. The length of the rectangles is 3 meters more than twice the width. Find the dimensions of the rectangle.
Step-by-step explanation:
Equation for Perimeter of a rectangle: Perimeter = 2W + 2L
Defining the variables, let
Width = x
Length = 2x+3 (3 more than twice the width)
Plugging everything into the equation
30= 2(x) + 2(2x+3) using the distributive property,
30=2x+4x+6 combining like terms
30=6x+6 subtracting 6 from both sides,
24=6x divide both sides by 6
4=x This means that the width is 4 m
To get the length, use the expression L=2x+3 and plug in x = 4 that was already solved for
L=2(4)+3
L=8+3 = 11 m
So the dimensions of the rectangle are width is 4 m and length is 11 m

A kite is flying at a height of 65 m attached to a string. If the inclination of the string with the ground is 31°, find the length of string.
Show your work please
Answer:
let KL be the string PL be perpendicular distance between them. and KL be height of kite flying.
in right angled triangle
relationship between perpendicular and hypotenuse is given by sin angle
sin 31°=p/h
h=65/sin31
KP=126.2m
the length of string is 126.2m
Answer:
127.45 m
Step-by-step explanation:
Given :-
Height of kite = 65 m .Inclination of string = 31° .To Find :-
The length of the string .Solution :-
Here we need to find out the length of the string here if we imagine a right angle triangle in which the height of the kite will be the perpendicular of the triangle and the length of the string will be the hypotenuse of triangle .
And the angle between the the string and the ground will be 31°.
Here we can use ratio of sine as ,
> sin∅ = p/h
> sin 31° = 65m/ h
> h = 65m/sin 31°
> h = 65m/0.51
> h = 127 .45 m

Step-by-step explanation:
m=(y2-y1)/(x2-x1)
m=(-4-8)/(7-(-2))
m=-12/(7+2)
m=-12/9
simplify
m=-4/3
y-y1=m(x-x1)

Part A: Determine the scale factor.
Part B: Solve for the unknown variable of the larger floor.
Answer:
show stage and back stage
Step-by-step explanation:
The scale factor is 3 and the value of the unknown variable of the larger floor is 36 ft and this can be determined by using the given data.
Given :
Two-stage floors are in the shape of isosceles trapezoids. The small stage floor in the drama room is geometrically similar to the large stage floor in the auditorium.a) Let the scale factor be 'y'. So, the value of 'y' can be calculated as:
[tex]\begin{aligned}\\24 &= y \times 8\\y &= 3\\\end{aligned}[/tex]
So, the scale factor is 3.
b) The value of the unknown variable of the larger floor is calculated as:
[tex]\begin{aligned} \\12\times y &= x\\12\times 3& = x\\x&= 36\\\end{aligned}[/tex]
So, the value of the unknown variable of the larger floor is 36 ft.

Answer:
[tex]Q_1 = 498[/tex]
[tex]Q_3 =1052[/tex]
Step-by-step explanation:
Given
[tex]Data: 777,\ 498,\ 619,\ 379,\ 895,\ 1,256,\ 1052[/tex]
[tex]n = 7[/tex]
First, the data has to be arranged:
[tex]Data: 379,\ 498,\ 619,\ 777,\ 895,\ 1052,\ 1256[/tex]
Solving (a): Lower Quartile
This is calculated as:
[tex]Q_1 =\frac{1}{4} * (N + 1)th[/tex]
[tex]Q_1 =\frac{1}{4} * (7 + 1)th[/tex]
[tex]Q_1 =\frac{1}{4} * 8th[/tex]
[tex]Q_1 = 2nd[/tex]
The 2nd data is 498
Hence:
[tex]Q_1 = 498[/tex]
Solving (b): Third Quartile
This is calculated as:
[tex]Q_3 =\frac{3}{4} * (N + 1)th[/tex]
[tex]Q_3 =\frac{3}{4} * (7 + 1)th[/tex]
[tex]Q_3 =\frac{3}{4} * (8)th[/tex]
[tex]Q_3 =6th[/tex]
The 6th data is 1052
Hence:
[tex]Q_3 =1052[/tex]
Solving (c): Interquartile Range
This is calculated as:
[tex]IR = Q_3 - Q_1[/tex]
[tex]IR = 1052- 498[/tex]
[tex]IR = 554[/tex]

Answer:
7.2 inches
Step-by-step explanation:
First, we find the length of the legs, which are the sides that are parallel to the x- and y-axis.
The leg parallel to the x-axis is 6 inches long.
The leg parallel to the y-axis is 4 inches long.
After finding the length of both legs, we can use the Pythagorean Theorem to find the length of the hypotenuse: a² + b² = c²
a and b being the legs, and c being the hypotenuse
6² + 4² = c²
36 + 16 = c²
52 = c²
√52 = c
c ≈ 7.2 inches
