Answer:
68 %
Step-by-step explanation:
Let's call X to the random variable ''lengths of a lawn mower part''.
X ~ N(given mean;standard deviation)
X ~ N(4 in;0.2 in)
To find the percentage,first we are going to turn this random variable X into a random variable Z. Z will be a N(0;1)
We do this by subtracting the given mean to the original variable and dividing by it deviation.
P (3.8 in < X < 4.2 in) =
P [(3.8 in - 4 in) / (0.2 in)] < [(X - 4 in)] / (0.2 in) < [(4.2 in - 4 in) / (0.2 in)]
P ( -1 < Z < 1 ) = P (Z < 1) - P (Z< -1)
Where we can find P (Z < 1) and P (Z< -1) in any table of a N(0;1)
P (Z < 1) - P (Z< -1) = 0.8413 - 0.1587 = 0.6826 = 68%
Answer:
10/1
Step-by-step explanation:
You do
6÷ 3/5
Flip the 3/5 then multiply
6 ° 5/3
Reduce the numbers with the greatest common factor 3
So 2•5
And that's 10
Answer:
Step-by-step explanation:
It's like solving any equation, except we have letters instead of numbers .
k = 3tm + rs {subtract rs from both sides}
k - rs = 3tm {divide both sides by (3m)}
{swap sides}
m≠0
{m must be ≠0 because you cannot divide by 0. There is no t for m=0}
1. Measure and angle in degree
