Answer:
1.3%
Step-by-step explanation:
Phat = 0.53
1 - phat = 1 - 0.53 = 0.47
Sample size, n = 5913
Assume the confidence level = 95%
Zcritical at 95% = 1.96
Margin of Error = Zcritical * √(phat(1 -phat)) / n
Margin of error :
1.96 * √((0.53 * 0.47) / 5913)
1.96 * 0.0064905
= 0.0127215
= 0.0127215 * 100%
= 1.272%
= 1.3%

100,000^1/5 x a + 1,000,000^1/2 x a
Answer:
1010a
Step-by-step explanation:
Mathematically, when a number is raised to a fraction, it simply means we are to find the root of that number to the denominator of the given fraction
For example;
100,000^1/5
= 5 x√((100,000) = 10
Likewise;
1,000,000^1/2 = √(1,000,000) = 1000
Thus, we have it that;
10 * a + 1000 * a
= 10a + 1000a = a(1000 + 10) = 1010a

Answer:
11 persons chosen to participate in the survey
Step-by-step explanation:
A certain fraction or percentage of subjects or persons drawn randomly from a larger population is called a sample. A randomly selected set of sample will be representative of the population especially when it is impossible for the whole population to participate in the study. In the scenario above, the population or larger group would be the set of volunteers. The actual number of people chosen from the group of volunteers to participate in the survey is the sample, which are the 11 people chosen from the volunteers.

Amy had $28 dollar’s to spend on school supplies. After buying 7 pens, she had $20.30 left. How much did each pen cost including tax?
Answer:
Step-by-step explanation:
If Amy started with 28 dollars and bought 7 pens, then had 20.30 dollars, we can subtract to find the price of all 7 pens.
28-20.30=7.70 dollars
now to find the amount for EACH pen, we divide by 7
7.70/7=1.1
each pen costed Amy 1 dollar and 10 cents with tax
Answer:
$1.10
Step-by-step explanation:
$28-$20.30=$7.70
7.70 divided by 7= 1.10
so each pen must cost $1.10
