We are given the following data
n = 35
x = 50
s = 2
CI = 95% (z = 1.96)
The formula for the margin of error is
E = z s / √n
Substituting the given values
E = 1.96 (2) / √35)
E = 0.66 or 66%
Answer:
Probability of an event E = p(E) = (number of favorable outcomes of E)/(number of total outcomes in the sample space) This approach is also called theoretical probability. The example of finding the probability of a sum of seven when two dice are tossed is an example of the classical approach.

Answer:
A sequence is a chain of numbers all related. In this case, they are related by the rule "f(n + 1) = –10f(n)". Each number is called a term. Here is what the rule in this sequence means:
Since f(n + 1) is the "next" term and f(n) is the "current" term, to get to the next term, you take the current term and multiply by -10.
When they say f(1) = 1 it means that the first term (term number 1) is 1. When they ask "What is f(3)?", they are asking, "What is the 3rd term?"
Since term #1 is 1, then to find term #2, we multiply 1 by -10. So term #2 is -10. To find term #3, we take term #2 and multiply it by -10, so -10 x -10 = 100. So term #3 is 100

Step-by-step explanation:
This expression consists of two fractions that have no common denominator but do have -2 as a common factor in the numerators.
Factoring out the -2, we get:
-2(2p/3 + 1/5)
If you want to go further, we can determine the LCD (which is 15) and then combine the fractions within parentheses:
-2(10p/15 + 3/15)
We could now factor out the 1/15 in each fraction:
-2
---- (10p + 3)
15
Step-by-step explanation:
5.9 - 7.3 - 10.2 = -11.6 1. Subtract the first number (5.9) from the second number (7.3), you get -1.4 *the outcome is negative because the larger number is subtracted from the smaller number
-1.4 - 10.2 = -11.6 2. Subtract -10.2 from -1.4, when subtracting a negative number from a negative number you just add them together and put a negative sign in front so 1.4+10.2=11.6 and then you add the negative sign which would make it equal -11.6
-11.6 =-11.6
