K is the midpoint of line JL. J has coordinates (2, -1), and K has coordinates (-4, 3). What are the coordinates of L?

Well the midpoint formula to find the coordinates is ( (x₂ + x₁)/2 , (y₂ -+ y₁)/2 )
Basically you find the average of each points to find the midpoint. Well we already have the midpoint so  we plug our numbers in with variables to find the other point. Let's start with the x value of coordinate L:
(2 + x₁)/2 = -4    the 2 came from point J and the -4 came from the midpoint k.
2+ x₁ = -8
x₁ = -10        this is the  x coordinate of point L. Let's find the y
(-1 + y₁)/2 = 3
-1 + y₁ = 6
y₁ = 7      this is the y coordinate of L
L's coordinate is (-10, 7)

Find the value of x when m<2 = x + 64​
polet [3.4K]

Answer:

-9

Step-by-step explanation:

The triangle has two sides that are the same, so it is an isosceles triangle.  Therefore, the base angles are the same.

Angles of a triangle add up to 180°, so:

70 + (x + 64) + (x + 64) = 180

70 + 2x + 128 = 180

2x = -18

x = -9

A company establishes a fund of 120 from which it wants to pay an amount,C, to any of its 20 employees who achieve a high-perfor
Leno4ka [110]

Answer:

C=120/2=60

Step by step Explanation'

To solve this problem, we will need to apply trial-and-error calculation with the binomial distribution, even though it appears like Central Limit Theorem but it's not.

For us to know the value of C , we will look for a minimum integer such that having 'n' number of high performance level of employee has the probability below 0.01.

Determine the maximum value of C, then the maximum value that C can have is 120/n

Let us represent X as the number of employees with high performance with a binomial distribution of

P =0.02( since the percentage of chance of achieving a high performance level is 2%)

n = 20 ( number of employees who achieve a high performance level)

The probability of X= 0 can be calculated

P( X= 0) = 0.98^n

P(X=0)=0.98^20

P(X=0)=0.668

P(X=1)=0.02*20*0.98^19

P(X=1)=0.272

P(X=2)=0.02^2*20*0.98^18

P(X=2)=0.053

Summation of P( X= 0)+ P( X= 1)+P( X= 2) will give us the value of 0.993 which is greater than 0.99( 1% that the fund will be inadequate to cover all payments for high performance.)

BUT the summation of P( X= 0)+ P( X= 1) will give the value of 0.94 which doesn't exceed the 0.99 value,

Therefore, the minimum value of integer in such a way that P(X >2) is less than 0.01 have n= 2

then the maximum value that C can have is 120/n

C=120/2=60
