Answer:
0.16 * 100 = 16%
Step-by-step explanation:
Answer:
0.2839 = 28.93%
Step-by-step explanation:
In order to find find the probability that one car chosen at random will have less than 68.5 tons of coal, we have to find z
Le x be tons of coal in a car
Z = (x – mean)/standard deviation
Z = (x – μ)/ σ
P (x<68.5) = P(z < (68.5-69)/0.9)
P (x<68.5) = P(z < -0.5555)
Then we use the z table to find the area under the curve.
P (x<68.5) = 0.2893
Answer:
A and B are independent events.
P(A) = 0.30. P
This diagram shows how 2/7 = 8/28 by showing that you can color in more squares or duplicate that amount of squares 4 times in order to get 8/28. (Since 2/7 x 4/4 = 8/28.)
Answer:
The equation of the line is.
Step-by-step explanation:
Given:
The given points are (0, -4) and (-4, 6)
The equation of the line passing through the points 
and 
is.
Thus, the equation of the line that passes through the points (0, -4) and (-4, 6) is
The above equation is divided by 2 both sides.
Therefore, the equation of the line that passes through the points (0, -4) and (-4, 6) is
