Answer:
B) 16%
Step-by-step explanation:
First, we need to standardize 58 and 66 inches using the following equation:
Where m is the mean and s is the standard deviation, so 58 and 66 are equivalent to:
Then, the percent of men whose heights falls between 58 inches and 66 inches is calculated as:
P(58<z<66) = P(-3<z<-1)
So, using the normal table, we get:
P(-3<z<-1) = P(z<-1) - P(z<-3)
P(-3<z<-1) = 0.1587 - 0.0013
P(-3<z<-1) = 0.1574
Finally, 0.1574 rounded to the nearest whole percent is equal to 16%
8x12 i am asssuming that that’d what it is
Step-by-step explanation:
second one because
only x+2y=8 passes through the point (2,3)
the proof is 2+2*3=2+6=8
if we replace the given point to the other equations we will take wrong results for example
first equation
x+2y=4. 2+2*3=2+6=8 that is not equal to 4
Answer:
27/4 or negative 3/4
Step-by-step explanation:
First we can simplify f(x) to make it a little easier. We can write it as
4x^3+2x^2-7x+4 by combining like terms
The we just subtract g(x) from f(x) and simplify
4x^3+2x^2-7x+4-(5x^3-7x+4) and remember to distribute the negative to g(x)
4x^3+2x^2-7x+4-5x^3+7x-4 (combine like terms)
-x^3+2x^2
In factored form, this becomes
-x^2(x-2)
Hope this helps
