Breanna exercises for 4 and 1/2 hours during the six days.
To find the answer, we have to multiply 3/4 by 6.
To do this, we change 6 to 6/1 and multiply straight across.
3/4 x 6/1 = 18/4 = 9/2
9/2 is the same as 4 and 1/2
Answer:
The probability of a random unit is deemed faulty if it scores below 320.
P( X < 320 ) = 0.0505
Step-by-step explanation:
<u><em>Explanation:-</em></u>
Given mean of the Population 'μ' = 374
Variance of the Population σ² = 1090
Standard deviation of the Population 'σ ' = √1090 = 33.01
Given 'X' be a random variable in normal distribution
Z = - 1.64
The probability of a random unit is deemed faulty if it scores below 320.
P( X < 320 ) = P( Z < - 1.64 )
= 1- p(Z > 1.64)
= 1 - ( 0.5 + A(1.64)
= 0.5 - 0.4495
= 0.0505
The probability of a random unit is deemed faulty if it scores below 320.
P( X < 320 ) = 0.0505
The numerical value of 700 km in miles will be;
⇒ 420 miles
What is Measurement unit?
A measurement unit is a standard quality used to express a physical quantity. Also it refers to the comparison between the unknown quantity with the known quantity.
Given that;
The number is,
⇒ 700 km
And, 5 km = 3 mile
Now,
We need to change 700 km in miles by using 5 km = 3 mile.
Since, 5 km = 3 mile
So, 1 km = 3/5 mile
Hence,
700 km = 700 x 3/5 miles
= 420 miles
Thus, The numerical value of 700 km in miles will be;
⇒ 420 miles
