What is the measure of the unknown angle? 7 50° n
Answer:
310°
Step-by-step explanation:
360 - 50 = 310
A full circle is 360, therefore you just need to take away the degree they gave you from it in order to find the remaining angle.
A population of five families is to be sampled. The incomes of the five families (in thousands of dollars) are: Family Income ($000) A 12 B 23 C 18 D 7 E 16 a. Find the population mean income of the five families. 2 point
The population mean income of the five families is their average income
The population mean income of the five families is #15.2
How to determine the population mean?The income of the five families in a thousand dollars is given as:
A 12 B 23 C 18 D 7 E 16
The population mean is then calculated as:
[tex]\mu = \frac{\sum x}n[/tex]
So, we have:
[tex]\mu = \frac{12 + 23 + 18 + 7 + 16}5[/tex]
Evaluate the sum
[tex]\mu = \frac{76}5[/tex]
Evaluate the quotient
[tex]\mu = 15.2[/tex]

A bike costs $650.00. Then it is marked down 35%
What is the final sale price of the bike?
PLEASE ANSWER QUICKLY
Answer:
$422.50
Step-by-step explanation:
If the bike is marked down by 35% then the final sale price will be 65% of the original price (since 100% - 35% = 65%).
Convert 65% into a decimal: 65% = 65/100 = 0.65
Therefore, 65% of $650 = 0.65 × 650 = $422.50
We need first mark downed amount
[tex]\\ \rm\Rrightarrow 0.35(650)=227.5[/tex]
Marked down price

X+3y - 2z=2
3x+2y+z=13
-2x+3y - 3z= -5
Answer:
{x,y,z}={1,3,4}
Step-by-step explanation:
System of Linear Equations given :
[1] x + 3y - 2z = 2
[2] 3x + 2y + z = 13
[3] -2x + 3y - 3z = -5
Solve by Substitution :
// Solve equation [2] for the variable z
[2] z = -3x - 2y + 13
// Plug this in for variable z in equation [1]
[1] x + 3y - 2•(-3x-2y+13) = 2
[1] 7x + 7y = 28
// Plug this in for variable z in equation [3]
[3] -2x + 3y - 3•(-3x-2y+13) = -5
[3] 7x + 9y = 34
// Solve equation [3] for the variable y
[3] 9y = -7x + 34
[3] y = -7x/9 + 34/9
// Plug this in for variable y in equation [1]
[1] 7x + 7•(-7x/9+34/9) = 28
[1] 14x/9 = 14/9
[1] 14x = 14
// Solve equation [1] for the variable x
[1] 14x = 14
[1] x = 1
// By now we know this much :
x = 1
y = -7x/9+34/9
z = -3x-2y+13
// Use the x value to solve for y
y = -(7/9)(1)+34/9 = 3
// Use the x and y values to solve for z
z = -3(1)-2(3)+13 = 4
Solution :
{x,y,z} = {1,3,4}

If the area of a triangle is 100 in^2, and the height is 10in, find the length of the base in inches.
Round to the nearest inch if applicable.
Answer:
Area of a triangle is 100 in²
Height of triangle is 10 in .
we have been asked to find the length of its base .
Formula Used to Find length of its base
☯[tex] \bf\: Area \: of \: triangle \: = \dfrac{1}{2} \times base \: \times height \: [/tex]
Put the given value we obtain
[tex] \rm \implies \: 100 = \dfrac{1}{2} \times base \: \times 10 \\ \\ \rm \implies \: 100 = \dfrac{1}{ \cancel2} \times base \: \times \cancel{10} \\ \\ \rm \implies \: 100 = base \: \times 5 \\ \\ \rm \implies \: base \: = \dfrac{100}{5} \\ \\ \rm \implies \: base \: = \cancel\dfrac{100}{5} \\ \\ \rm \implies \: base \: = 20 \: inch[/tex]
So, the length of its base is 20 inch .
The base length of the triangle with the given values of area and length of height to the nearest inch 20in.
What is a triangle?
A triangle is a two-dimensional shape with three edges and three vertices.
The area of a triangle is expressed as;
A = (1/2) × base × height
Given the data in the question;
Area of the triangle A = 100in²Length of Height = 10inLength of Base = ?We substitute our given values into the expression above.
A = (1/2) × base × height
100in² = (1/2) × Base × 10in
100in² = 0.5 × 10in × Base
100in² = 5in × Base
Base = 100in² / 5in
Base = 20in
Therefore, the base length of the triangle with the given values of area and length of height to the nearest inch 20in.

let f(x)=3-3x+5x^2.calculate the following.
f(a)=
f(a+h)=
f(a+h)-f(a)/h= for h≠0
Answer & step-by-step explanation:
[tex]f(a)[/tex] is simply calculating by replacing a in lieu of x
[tex]f(a) = 3-3a+5a^2[/tex]
Same difference for [tex]f(a+h)[/tex], just be careful with products and squares:
[tex]f(a+h) = 3-3(a+h)+5(a+h)^2 = 3-3a-3h+5a^2+10ah+5h^2 = 3-3a+5a^2 -3h+10ah+5h^2[/tex]
In the last step i just reorganized terms so that everything containing h was at the end.
Finally, for the incremental ratio, writing it as 1/h for the sake of font sizes:[tex]\frac{f(a+h)-f(a)}h = \frac1h[(3-3a+5a^2-3h+10ah+5h^2)-(3-3a+5a^2)]=\\\frac1h(-3h+10ah+5h^2) = 10a-3 +5h[/tex]

The map shows the location of the houses of Dan, Joe, Lee, and Roy:
The coordinates of the community center are (−5, −1). Who has a house in the same quadrant as the community center?
a Dan
b Joe

Answer:
c Lee
Step-by-step explanation:
The coordinates of the community center are both negative. They place it 2 units left and 3 units up from Lee's house in the 3rd quadrant.
In an isosceles triangle (a triangle where two of the three sides called legs are equal), the legs
are 1 unit less than twice the length of the base. If the length of the base of the triangle is
represented by x, create an expression that represents the perimeter of the triangle.

A ladybug and ant move at constant speeds. The diagrams with tick marks show their positions at different times. Each tick mark represents 1 centimeter. Lines u and v also show the positions of the two bugs. Which line shows the ladybug’s movement?
Answer:
Line u shows the movement of the ladybug. Because line v goes farther than line u
Step-by-step explanation:
Because line v goes farther than line u
The ladybug's motion is depicted in line u. Because line v is moving farther than line u.
What is Speed?The amount of the shift in approach per unit of time or the size of the displacement over time for an object can be used to describe speed, which would be a scalar quantity in everyday language and kinematics.
The maximum speed that can be maintained when a period grows closer to zero is the starting speed.
By dividing the object's distance traveled by the duration of the interval, the mean pace of the object for the given period is calculated. Speed and velocity are not always the same thing.
The line u and v show the position of the two bugs, but the line that shows the ladybug's movement is line u because line v is moving farther than line u.

The perimeter of rectangle is 36 the length is 3 more than two times the width
Answer:
The width of the rectangle is equal to 5 and the length is equal to 13
Step-by-step explanation:
Perimeter of rectangle = (Length + Width) ×2
Perimeter of rectangle = (13 + 5) ×2
Perimeter of rectangle = 36
The length of the rectangle is 13, which is 3 more than two times the width, if the width is 5
5 (Width) ×2 = 10

• Can you list down similarities of your experience with your circle of friends?
A recent study published in Nature Communications says the reason for this likeness is that best friends actually have similar — or sometimes identical — brain activity.. Yup , your closest friends "get you" because it's like their basically looking in the mirror.. Friends and tend to have certain characteristics in common , Such as Age, Education and even intelligence — and yet , Research has long suggested that personality isn't one of these commonalities.. Some scientific research has shown how you're likely to be attracted to people who share similar facial characteristics as you. One theory for this is that we associate people who look like us with our parents, and thus have more positive feelings towards their features. Similarities are also important for friendships.
