C.36
you would multiply 30 times 20, then divide that total by 100 which will give you 6 then add the 6 to the 30 and get 36.
Answer:
Teachers in his school district have less than 5 yearſ of experience on average is true.
Step-by-step explanation:
Sample mean =
Sample standard deviation = s = 2
We are supposed to to test Ha :u= 5 versus H : u < 5 using a sample of 25 teachers
n = 25
Since n<30 and population standard deviation is unknown
So, we will use t test
Formula :
t=-2.5
Degree of freedom = n-1 = 25-1 = 24
Refer the t table
t critical > t calculated
So, We are failed to reject null hypothesis
So, teachers in his school district have less than 5 yearſ of experience on average is true.
Answer:
Step-by-step explanation:
Lets suppose the one side be x and the other side of the rectangle be y
given area
implies x = 650/y
Cost = 2*4*x+2*3*y=8x+6y
= 8*650/y + 6y
= 5200/y + 6y
upon differentiating we get
=
= 2600/3
y= = 43.3
x= 15
C(43.3)= >0 hence it is a minima value
optimizing the result we get
Cost = 8*15+6*43.3 =$ 379.8
Answer:
Bart lives 9 1/6 miles from Quickie Mart.
Step-by-step explanation:
So, 2.5 is equal to 2 1/2.
So first turn each mixed number into a improper fraction.
3 2/3 becomes 11/3 and 2 1/2 becomes 5/2.
11/3 * 5/2 = 55/6
55/6 is simplified to become 9 1/6
