<span>Answer:
The notation for the uniform distribution is
X ~ U(a, b), where a = the lowest value and b = the highest value
In your case, X ~ U(66,89)
µ = (b+a)/2
Ď = (b-a)²/12
In this case, a = 66 and b = 89
Thus,
µ = (89+66)/2 = 77.5
Ď = (89-66)²/12 = 44.0833
Then, because we now know the true/population µ and Ď, we can use z-scores.
z = (X-µ)/Ď
In our case, X = 71. So,
Z = (X-µ)/Ď
Z = (71-77.5)/44.0833 = -0.15
P(Z>-0.15) = P(Z<0.15) = 0.5596</span>
It’s not scaled. You can see it’s not the same shape as image A. 1 is only added to the height. If a shape is scaled, then the shape will remain the same, however it’s size will not. Therefore, the answer is “not a scaled copy of image A because 1 is added to the height”
Answer:
Unlikely = greater Than 0 ; less than
Likely = greater than 0.5 ; less than 1
Neither likely nor unlikely = 0.5
Step-by-step explanation:
Probability values usually range between standardized values between 0 and 1. With values closer to 1 depicting greater possibilities of an event. Probability value of zero means certain and probability value of 0 zero means.impossible.
Using this standardized values :
An unlikely event is more of not occurring than occurring (that is the event has higher chances of not happening) ;
Hence; We can categorize unliky events to range from below the mid value to greater Tha.n 0
Unlikely event : greater Than 0 ; less than 0.6
Events with probability above the mid value of 0.5 have higher chances of occurring (greater likelihood) hence, Probability is greater than 0.5 but less than 1.
Neither likely nor unlikely event will take the boundary point between likely and unlikely = 0.5
Those are right ...........................
Answer:
Step-by-step explanation:
C. 5 1/8 + 3/4 = h
Since Charlies heigh is 5 1/8 feet tall. It says Sahil is 3/4 foot taller then Charlie. So 5 1/8 + 3/4 = Sahil height
