Answer:
d. .00012 or 0.00012
Step-by-step explanation:
The variance of the population proportion formula is given as:
p(1 - p)/n
Where n = sample size
p = population proportion or p(hat)
n = 2000 people
p = 0.52
Variance of the population proportion = 0.52(1 - 0.52)/ 2000
= 0.52 × 0.48 /2000
= 0.2496 /2000
= 0.0001248
Therefore the Variance of the population proportion is approximately = 0.00012
Answer:
multiplication.
Step-by-step explanation:
A good way to remember the order of operations is Please Excuse My Dear Aunt Sally, or PEMDAS. PEMDAS stands for Parentheses, Exponents, Multiplication/Division, Addition/Subtraction. If multiplication and division are in the same problem, you go in order. Same with addition in subtraction. What that means in this example is that since in PEMDAS, the M is first, you would multiply first instead of subtracting. :)
Answer:
t=0
Step-by-step explanation:
The first thing you want to do is isolate the varible t. So you going to subrtact the 45 from both sides, which leaves you with, 5t=0. Next you are going to divide 5 from both sides, which leaves you with t=0. To make sure its right, plug it in. 45+5(0)=45. 45=45.
