Answer:

C- $4,822

Step-by-step explanation:

4% of 41300 is 1652

4.5% of 44100 is 1984.5

3% of 39500 is 1185

1185 + 1984.5 + 1652 = 4821

4822 is 1 number away from 4821, which is the closest of all of the choices. Therefore the answer is C- 44,822. If this answer helped you please consider giving it brainliest.

The proportion of items in a population that possess a specific attribute is known to be 0.45. a. If a simple random sample of s

yanalaym [24]

Answer: 0.05

Step-by-step explanation:

Sampling error is the error occurs by considering sample for study instead of entire population.

Given : The proportion of items in a population that possess a specific attribute is known to be 0.45.

Sample size : n= 100

Sample proportion of items in a population that possess a specific attribute : $\hat{p}=0.48$

Now, the formula to find the sampling error :

$\text{Sampling error} =\sqrt{\dfrac{\hat{p}(1-\hat{p})}{n}}$

$\text{Sampling error} =\sqrt{\dfrac{0.48(1-0.48)}{100}}$

$=\sqrt{\dfrac{0.48(0.52)}{100}}\\\\=\sqrt{0.002496}\approx0.05$

Hence, the sampling error =0.05

Solving systems of equations using substitution/elimination

Step-by-step explanation:

Step 1: Define Systems

y = 2x + 3

y = x + 2

Step 2: Solve for x

Substitution

Substitute in y: 2x + 3 = x + 2
[Subtraction Property of Equality] Subtract x on both sides: x + 3 = 2
[Subtraction Property of Equality] Subtract 3 on both sides: x = -1

Step 3: Solve for y

Substitute in x [Original Equation]: y = -1 + 2
Add: y = 1
