Answer:
Step-by-step explanation:
arrange the data from ascending to descending order
since the data is already in ascending to descending order dont change.so,
first quartile=(N+1)/4 (N is number of data)
=(7+1)/4
=8/4
=2 nd term
=48
Answer:
= 48
Step-by-step explanation:
=(7+1)/4
=8/4

What is the value of x?
Answer:
x =127
Step-by-step explanation:
Since this is a 6 sided figure, the sum of the interior angles is 720
128+133+112+x+120+100 = 720
Combine like terms
x+593=720
Subtract 593 from each side
x+593-593 = 720-593
x =127
Hint :
Sum of angles of the 6 sided figure = [tex] {720}^{o} [/tex]
Answer:
[tex] {x}^{o} = {127}^{o} [/tex]
Step-by-step explanation:
[tex] {x}^{o} + {112}^{o} + {133}^{o} + {128}^{o} + {100}^{o} + {120}^{o} = {720}^{o} \\ {x}^{o} + {593}^{o} = {720}^{o} \\ {x}^{o} = {720}^{o} - {593}^{o} \\ {x}^{o} = { 127}^{o} [/tex]
Hope it is helpful....Martha’s biweekly gross pay is $1,000. Her deductions make up 23% of her gross pay. How much is deducted from her pay for a full calendar year?
$4,600
$5,980
$7,020
$9,420
ALL GIVE BRAINLY
Answer:
$5,980
Step-by-step explanation:
23% of $1,000 = $230
so, Martha's deductions for a full calendar year =
52/2 × $230 = $5,980

Answer:
Step-by-step explanation:
A town has a population of 5600 in 2014. If the towns population increases at an annual rate of 1.8%, determine the towns population in 2020. *
Answer:
In 2020 the population will be 6,233.
Step-by-step explanation:
Giving the following information:
Present value (PV)= 5,600
Growth rate (g)= 1.8%
Number of periods= 6 years
To calculate the population in 2020, we need to use the following formula:
FV= PV*(1 + g)^n
FV= 5,600*(1.018^6)
FV= 6,232.67 = 6,233
In 2020 the population will be 6,233.

write an equation then find the angle measure for A. 25 points and brainliest.
Answer:
A
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180°
Sum the 3 angles and equate to 180
4 + 3x + 3x + 14 + 90 = 180 , simplify left side
108 + 6x = 180 ( subtract 108 from both sides )
6x = 72 ( divide both sides by 6 )
x = 12
Then
∠ A = 4 + 3x = 4 + 3(12) = 4 + 36 = 40° → A
pls help i am really struggling at this it is a vector question
Answer:
Step-by-step explanation:
PQ = q-p
PQ = q-p, therefore PS = (2/3)(q-p)
OS = p + (2/3)(q-p) = (2q+p)/3
OR = q + p/2
To make new vectors, chain vectors, follow arrow directions.

OXZ = 2(XY)
YZ is the longest segment in AXYZ.
Answer:
1 and 3 on edg
Step-by-step explanation:
The correct statements are YZ = 9 cm and XZ = 9√2
What is a right triangle?A triangle with one angle equal to 90° is called a right triangle.
Given that, a right triangle XYZ, with acute angles 45°, we need to determine the correct statements regarding the triangles,
Since, the acutes angles are equal, therefore, sides opposite to them will also be equal,
XY = YZ = 9 cm
Using the Pythagoras theorem,
XY² + YZ² = XZ²
XZ² = 9²+9²
XZ = √162
XZ = 9√2
The longest side is always opposite to the largest angle, which is XZ.
Hence, the correct statements are YZ = 9 cm and XZ = 9√2

Step-by-step explanation:
given that ABCD is a rhombus, what is the value of x?
answers
a.) 28
b.) 56
c.) 48.5
d.) 18
e.) 36
f.) Cannot be determined
Answer:
d
Step-by-step explanation:
We know that diagonals bisect angles of a rhombus, meaning that they split the angles of two equal parts, that opposite angles are equal, and that the angles of a quadrilateral, such as a rhombus, add up to 360 degrees.
Looking at the drawing I uploaded, and taking into account that diagonals bisect angles of a rhombus, we can say that angle x = y and z = 5x-18
Next, given that opposite angles are equal, we can say that angle B = angle D and angle A = angle C. Therefore,
A+B+C+D= 360 (as the angles of a quadrilateral add up to 360)
A + B + A + B = 360 (plugging in A for C and B for D)
2 ( A + B) = 360
A + B = 180
x + y + z + 5x - 18 = 180 (plugging x+y in for A, and z+5x-18 in for B, as x and y make up A and z and 5x-18 make up B)
x+x+5x-18+5x-18 = 180 (because x=y and z=5x-18)
2(x+5x-18) = 180
divide both sides by 2
x+5x-18=90
6x-18=90
add 18 to both sides
6x=108
divide both sides by 6
x = 18

Tell whether the triangle with the given side lengths is a right triangle.
24, 70, 75
Answer:
Not a right triangle.
Step-by-step explanation:
We can tell if it's a right triangle or not by using the Pythagorean Theorem.
The largest value is always the hypotenuse (c).
a² + b² = c²
24² + 70² = 75²
576 + 4900 = 5625
5476 ≠ 5625
The values do not equal one another. Therefore, this triangle is NOT a right triangle.
