Answer:

It increases confidence because the more times you conduct the same experiment over and over should either prove your hypothesis right and wrong and eliminate any random occurrences that might affect your results.

A car traveling at a speed of 50.0 m/s encounters an emergency and comes to a complete stop. How much time will it take for the

ludmilkaskok [199]

Answer:

t=1.25s

Explanation:

The formula is

a= (V1-V0) /t

t = (V1-V0)/a

V1=50m/s

V0= 0 m/s

a= - 4m/s2

t= (0-50)/-4 = 1.25s

When Emeka was first training his dog, Smooches, to heel he would give Smooches a treat when she stayed close during walks. Now

shepuryov [24]

Answer a. is correct. In this case the dog treats were positive reinforcers for staying close (the desirable behaviour). Repeated rewards for a certain behaviour work as positive reinforcers.

An object slides down a frictionless inclined plane. At the bottom, it has a speed of 9.80 m/s. What is the vertical height of t

Papessa [141]

The vertical height of the given plane is 4.9 m.

The given parameters:

speed of the object at the bottom of the ramp, v = 9.8 m/s

The vertical height of the plane is calculated by applying principle of conservation of mechanical energy as follows;

$P.E = K.E\\\\mgh = \frac{1}{2} mv^2\\\\h = \frac{v^2}{2g} \\\\h = \frac{9.8 \times 9.8}{2 \times 9.8} \\\\h = 4.9 \ m$

Thus, the vertical height of the given plane is 4.9 m.

I hope some one can help me!

zloy xaker [14]

Given that:
μ = 36
σ = 3

Standardize x to z = (x - μ) / σ 
P( 39 < x < 42) = P[( 39 - 36) / 3 < Z < ( 42 - 36) / 3] 
P( 1 < Z < 2) = P( x < 2) - P( x < 1)
= 0.9772 - 0.8413
= 0.1359 

(0.1359)(30)
= 4.0777
= 4 days
