Answer:
k=0,5/4(fraction)
Step-by-step explanation:
I hope this helps! :) You need to divide both sides.
The probability is 0.9671.
The z-score for this is given by
z = (x - μ)/(σ/√n)
z = (38000-37500)/(1561/(√33)) = 1.84.
Using a z-table (http://www.z-table.com) we see that the area under the curve to the left of, less than, this is 0.9671.
Answer:
D(4) = 6
Step-by-step explanation:
Using the blue graph, find the y value when x =4
the y value is 6 when x=4
D(4) = 6
Answer:
y=1/2x+9
Step-by-step explanation:
By the least steep graph, it means the "smallest" slope. The smaller the slope is, the less steep it'd be. The slope can be positive or negative, too.
1/4x<-1/2x<2x<-6x
Therefore, y=1/2x+9 would be the equation with the least steep graph.
I hope this helped! Have a good day!
Answer:
Step-by-step explanation:
For plane A,
Equation that represents the relationship between time 'x' and distance 'y' is,
y = 470x
By comparing this equation with the slope-intercept form of the equation,
y = mx + b
m = slope = 470
b = 0
Here, slope represents the speed of plane A.
Therefore, speed of plane A = 470 mi per hour
For plane B,
From the given table,
Slope of the graph = 
= 
= 480
Speed of plane B = 480 miles per hour
Since, speed of plane B is more than plane A,
Plane B is flying faster.
