Answer:
0.77,0.60
Step-by-step explanation:
Given that in a population of 1000 subjects, 770 possess a certain characteristic.
A sample of 40 subjects selected from this population has 24 subjects who possess the same characteristic
To find out sample proportion:
Sample size n = 40
Favourable x = 24
Sample proportion p = 
To find out population proportion:
Total population N = 1000
Favourable X = 770
population proportion P = 
Answer:
3 gallons
Step-by-step explanation:
Let
x ----> the amount of pure acid (100% solution) in gallons
Remember that
we know that
solve for x
therefore
3 gallons of pure acid should be mixed with 3 gallons of a 20% acid solution in order to get a 60% acid solution
The total amount of lenght that the line will have depends on the amount of strips, and the result is equal to the multiplication of the amount of strips, x, and the length of the strips 3/8 inch
total_length = (3/8)x
where x is the amount of strips, and the total length is in inches
Answer:
x=11
Step-by-step explanation:
start with
x-2=9
then write x-2=9 with +2 underneath both sides of the equal sign
then slash through the twos, and add two and nine to get x by itself.
