Answer:

 x =  68/33

Explanation:

Step 1: Simplify both sides of the equation.

Step 2: Subtract 2/5x from both sides.

Step 3: Add 80 to both sides.

Step 4: Multiply both sides by 5/198.

Please help! Greatly appreciated sorry for really bad quality
Degger [83]
The first answer.

Point P is at (50,-40) the distance from Q to P is 80 units which you can find by subtracting the x of Q (-30) from the x of P (50).
50-(-30)=80
It then tells you point R is vertically above point Q so you know your x value for R will be the same as Q.
Add your distance from Q to P of 80 units to the y value of Q because you are traveling up.
-40+80=40
R will have a point of (-30,40) and a distance of 80 units

X is a normally Distributed random variable with a standard deviation of 4.00. Find the mean of X when 64.8% of the area lies to
Cerrena [4.2K]

Answer:

7

Step-by-step explanation:

σ = 4 ; μ =?

8.52 to the left of X

.

P(X < 8.52) = 64.8%

P(X < 8.52) = 0.648

Using the Z relation :

(x - μ) / σ

P(Z < (8.52 - μ) / 4)) = 0.648

The Z value of 0.648 of the lower tail is equal to 0.38 (Z probability calculator)

Z = 8.52 - μ / 4

0.38 = 8.52 - μ / 4

0.38 * 4 = 8.52 - μ

1.52 = 8.52 - μ

μ = 8.52 - 1.52

μ = 7

The midpoint of \overline{\text{AB}} AB is M(0, -3)M(0,−3). If the coordinates of AA are (2, -5)(2,−5), what are the coordinates
ICE Princess25 [194]

Using the mid-point concept, it is found that the coordinates of B are (-2, -1).

  • The mid-point of two points is the <u>mean of the coordinates of each point</u>.

In this problem:

  • The points are: A(2, -5) and B(x,y).
  • The mid-point is (0, -3).

Applying the concept for both the x and y-coordinates, we have that:

\frac{x + 2}{2} = 0

x + 2 = 0

x = -2

\frac{-5 + y}{2} = -3

-5 + y = -6

y = -1

The coordinates of B are (-2, -1).
