The coordinates for each are:
A: (5,3)
B: (-3,-3)
Now we need to find the difference between the x and y.
x= 5 --3
x=5+3
x=8
y=3--3
y=3+3
y=6
Do now let's pretend it's a right angled triangle with side length 8 and 6:
8^2+6^2=h^2 Where h is the distance between between A and B
64+36=h^2
100=h^2
sqrt 100 is 10 so h=10
Meaning the answer is A
Hope this helps :)
Answer:
850 steps
Step-by-step explanation:
50cm=0.1m
85/0.1=850 steps
The answer I believe is c or d
Answer:
a) P(75 < x < 80 ) = 0.2088
b) The probability that average height of all humans less than 65
P( X < 65 ) = 0.0495
Step-by-step explanation:
<u><em>Step(i)</em></u>:-
Given mean of the Population = 72
Given variance of the Population = 18 inches.
Standard deviation of the Population = √18 = 4.242
Let 'x' be the random variable in Normal distribution
a)
Given X₁ = 75
Given X₂= 80
The probability that average height of all humans between 75 and 80
= | A ( 1.885) - A( 0.70721|
= 0.4699 - 0.2611
= 0.2088
P(75 < x < 80 ) = 0.2088
b)
<u><em>Step(ii)</em></u>:-
Given X₁ = 65
The probability that average height of all humans less than 65
P( X < 65 ) = P( Z < - 1.650 )
= 1 - P( Z > 1.650)
= 1 - ( 0.5 + A (1.650))
= 0.5 - A( 1.65)
= 0.5 - 0.4505
= 0.0495
The probability that average height of all humans less than 65
P( X < 65 ) = 0.0495
Answer:
A
Step-by-step explanation:
2/8 because there are 8 in total but only 2 are colored.
