Answer:
P(x< 18) = 0.986
Step-by-step explanation:
Step 1: find the z-score using the formula, z = (x - µ)/σ
Where,
x = randomly chosen values = 18
µ = mean = 7
σ = standard deviation = 5
Proportion of the population that is less than 18 = P(x < 18)
Plug in the values into z = (x - µ)/σ, to get z-score.
z = (18 - 7)/5
z = 11/5 = 2.2
Step 2: Find P(x< 18) = P (z<2.2) using z-table.
The probability that corresponds with z-score calculated is 0.986.
Therefore,
P(x< 18) = 0.986
Answer:
2nd one : y = -4/x
3rd one : y + x/2 = 9
4th one
5th one : y = x^2

Answer:
7 squared is 49, 9 cubed is 729 im not sure what the third one is
Step-by-step explanation:
7x7= 49
9x9x9=729
19 with that symbol usually means degrees like temperature
The equation for point slope form is written as :
y - y1 =m(x-x1)
M is the slope which is given as -37
The given point would be X1 and y1, where X1 is 5 and y1 is 8.
The equation becomes:
y - 8 = -37(x -5)
