Answer:
Sample proportion ; phat
x / n
Step-by-step explanation:
The sample proportion may be explained as a proportional representation of part of the population or larger sample which have a certain character or exhibit a particular trait.
The sample proportion is expressed Mathematically as ;
phat = x / n
x = number of subjects with a specified characteristic ;
n = total sample size
For instance ;
The proportion of black balls in a sample of 100 balls is 15 ; the sample proportion of bla k balls will be :
phat = x / n = 15 / 100 = 0.15
The best estimate would be around 350,000 to 450,000
Answer:
The y coordinate of the shape would be 7 more than its original value.
Step-by-step explanation:
Answer:
108 in
Step-by-step explanation:
The figures are similar, so if we find a relation of the area and the diagonal in rectangle 1 we can apply it to rectangle 2.
rectangle 1 :
72/x=12
x=6
therefore
72/6=12
rectangle 2:
A/x=18
A/6=18
6*18=108
A=108 in

Find the lateral area of a cylinder with the given measurements. Use 3.14 for pi and round your answer to the nearest tenth.
height: 15 centimeters
radius: 9 centimeters
Question 11 options:
787.3 cm2
1356.5 cm2
847.8 cm2
889.9 cm2
So we know the formula for the lateral area of a cylinder is:
AL=2πrh
now all we have to do is put the given value in place of the correct variable then solve like so:
AL=2*3.14*9*15
AL= 847.8 cm2
so the answer is the third option
hope this helps
