Answer:
the approximate probability that the total weight of the passengers exceeds 4668 pounds is 0.0089
Step-by-step explanation:
Using the central limit Theorem
z = (x - u )/Q÷ sqrt n
Where z is the z-score
x is the average weight = 4668/22 = 212.2
u is the passengers average = 194 pounds
Q is standard deviation = 36 pounds
Therefore
z= (212.2 - 194) / 36 ÷ sqrt22
= 18.2/ 36÷ 4.69
= 18.2/7.68
z=2.3698 aprx 2.37
Find the value of 2.37 z-score on the z-table to determine the approximate probability
P(z>2.37) = 0.0089 (from the z-table)
Answer:
if this is in an inequality problem no because you can only combine like terms such as combining m and m and no variable numbers together you cannot subtract a variable from a number unless you have what the variable is equal to. correct me if im wrong
Step-by-step explanation:
Slope-intercept form: y = mx + b (m is the slope, b is the y-intercept or the y value when x = 0 --> (0, y))
To find the slope(m), you can use the slope formula and plug in 2 points:
(x₁ , y₁) = (0, 2)
(x₂ , y₂) = (4, 5)
[slope is also 
"rise" is the number of units you go up(+ number) or down(negative number). "run" is the number of units you go to the right. If your slope for example is 2, you go up 2 units and to the right 1 unit. If your slope is -2, you go down 2 units and to the right 1 unit.]
^ you could just look at the graph and see how many units a point goes up or down and to the right to get to the next point (goes up 3, to the right 4)
To find b, plug in either of the 2 points into the equaation
(0,2)
2 = b

Step-by-step explanation:
Check the picture below.
so if we just find its vertex, we know how many feet it went up by its y-coordinate.
