Answer:
66.8% or 0.66772
Step-by-step explanation:
0.66772
Given that :
Mean (m) = 62
Standard deviation (s) = 4
probability that a data value is between 57 and 65
P(57 < x < 65)
Using the relation :
(x - m) / s
P(x < 57) :
(57 - 62) / 4 = - 1.25
P(Z < - 1.25) = 0.10565 ( Z probability calculator)
P(x < 65) :
(65 - 62) / 4 = 0.75
P(Z < 0.75) = 0.77337 (Z probability calculator)
P(Z < 0.75) - P(Z < - 1.25)
0.77337 - 0.10565 = 0.66772
Answer:
PR = 3.2
Step-by-step explanation:
We can use proportions to solve this problem. Put the first triangle side over the second triangle side.
BC AC
-------- = ----------
QR PR
Substituting in values
10 8
-------- = ----------
4 PR
Using cross products
10 PR = 8*4
10 PR = 32
Divide by 10
10 PR/10 = 32/10
PR = 3.2
Answer: 20
Step-by-step explanation: For every 6 adult camels there are 5 baby camels so if you add both together, you get 11 and if you multiply that times 4 you get 44. Now you multiply 4 times the 5 baby camels to go your answer, 20.
The answer is 70 miles per hour
