Answer:
a = 4
b = 5
Step-by-step explanation:
Assuming this is a square root.
We can rewrite 80 as 8*10 and 8 can be rewritten as or and 10 can be rewritten as 2*5
two 2's come out of the root and a 5 remains inside.
We don’t know the value for the population, so we must estimate the standard error using the data from the sample. Standard error = sqrt(p(1 - p)/n), where p is the proportion of yes and n is sample size. Margin of error = z* * standard error, z* = 1.64, so margin of error is 0.053. A sample size less than 10% of the population is needed to make an inference, thus, d is the correct answer. If this was confusing, please don’t hesitate to comment, hope this helps!
The magnitude size of -5.8 is 5.8
magnitude size of a number is the number itself, and if it’s negative, it becomes its absolute value (in other words, you remove the subtraction sign).
1/25 is the answer. (3/15)(3/15)=9/220
If you simplify that you get 1/25 - Credit <span>Ayanah</span>
