Step-by-step explanation:
The Mean Value of a Data Set
The mean or average of a data set is found by adding all numbers and then dividing by the number of values in the set. Written as a formula:
[tex]\displaystyle \bar x=\frac{\sum x_i}{n}[/tex]
Where xi is the value of each data and n is the total number of values.
We are given the average weight of n=5 marathon runners:
[tex]\bar x=92[/tex]
Multiplying the formula by n and expanding the sum:
[tex]n\bar x=\sum x_i=x_1+x_2+x_3+x_4+x_5[/tex]
We are given the weighs of four of the runners:
[tex]5*92=89+95+90+90+x_5[/tex]
[tex]460=364+x_5[/tex]
Solving for x5:
[tex]x_5 = 460-364=96[/tex]

The pentagons JKLMN and PQRST are similar.
Find the length x of PQ.
Answer:
x = 3.2
Step-by-step explanation:
Since both polygons are similar, therefore their corresponding lengths would be proportional to each other.
Thus,
[tex] \frac{QP}{KJ} = \frac{TP}{NJ} [/tex]
[tex] \frac{x}{4} = \frac{4}{5} [/tex]
Multiply both sides by 4
[tex] \frac{x}{4}*4 = \frac{4}{5}*4 [/tex]
[tex] x = \frac{4*4}{5} [/tex]
x = 3.2

How many solutions does this system of equations have? y=3x+1 y=3x+7
Answer:
The following system of equation has no solution.
Step-by-step explanation:
since both of them are equal to y, set them equal to each other:
3x+1=3x+7
if you subtract both sides by 3x, you get 1=7. That is a contradiction, so this has no solutions.
This equation has no solution.
What is the inconsistent system?An inconsistent system is a system that has no solution in any case scenario.
Given this system of equations y=3x+1, y=3x+7.
on comparing both equations multiples of x and y are equal therefore, there will be no solution for a given equation.

Find the discriminant of the equation and give the number and type of solutions of the equation 4x^2+2x-5=0
Please help fast!!
Answer:
The answer is 84.
Step-by-step explanation:
The given equation is
4x*2 + 2x -5 = 0
Here a= 4, b= 2, c= -5
Since Discriminant= b*2 -4ac
Putting values
Discriminant= (2)*2 - 4(4)(-5)
= 4 + 80
= 84
Since our Discriminant(84) is >0 and is not a perfect square so the roots of the given equation are unequal and irrational(real).

Part II: Find the angle O in radians, (2 points)
The circle has radius 6 feet, so its total circumference is 2π • (6 ft) = 12π ft.
As an arc, the complete circle corresponds to a central angle of 2π radians. So the red arc corresponds to a central angle θ such that
θ / (15 ft) = (2π rad) / (12π ft)
Then
θ = (15 ft) • (2π rad) / (12π ft) = 15/6 rad = 2.5 rad

Answer:
11. Slope of the line is 7/10.
12. Slope of the line is [tex]-\frac{1}{3}[/tex]
Step-by-step explanation:
11. Given points are:
(-6, 1) and (4, 8)
Slope of a line is given by the formula;
m = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]
m = [tex]\frac{8-1}{4-(-6)}[/tex]
m = [tex]\frac{7}{4+6}[/tex]
m = [tex]\frac{7}{10}[/tex]
Slope of the line is 7/10.
12. Given points are:
(2, -3) and (5, -4)
Slope of the equation is;
m = [tex]\frac{-4-(-3)}{5-2}[/tex]
m = [tex]\frac{-4+3}{3}[/tex]
m = [tex]\frac{-1}{3}[/tex]
Hence,
Slope of the line is [tex]-\frac{1}{3}[/tex].
