Answer:
50/100
Step-by-step explanation:
Here is the work for this equation:
2+9-x/4 =10
11-x/4=10
11-x=40
x=29
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:
There is two equations because it has to have two. One is going to have a positive answer and the negative answer. It just depends on the question and what it is asking g you
Answer:
The slope of the line with points A(-2, -7) and B(3,5) is m = (12/5).
Step-by-step explanation:
The two pints are given as A(-2, -7) and B(3,5)
Slope of a line with points (a,b) and (c,d) is given as
So, here the slope of line AB is
or, m = 12/5
Hence, the slope of the line with points A(-2, -7) and B(3,5) is (12/5).
