we believe that 42% of freshmen do not visit their counselors regularly. For this year, you would like to obtain a new sample to estimate the proportiton of freshmen who do not visit their counselors regularly. You would like to be 98% confident that your estimate is within 3.5% of the true population proportion. How large of a sample size is required
Answers
Answer:
A sample of 1077 is required.
Step-by-step explanation:
In a sample with a number n of people surveyed with a probability of a success of [tex]\pi[/tex], and a confidence level of [tex]1-\alpha[/tex], we have the following confidence interval of proportions.
[tex]\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]
In which
z is the zscore that has a pvalue of [tex]1 - \frac{\alpha}{2}[/tex].
The margin of error is of:
[tex]M = z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]
42% of freshmen do not visit their counselors regularly.
This means that [tex]\pi = 0.42[/tex]
98% confidence level
So [tex]\alpha = 0.02[/tex], z is the value of Z that has a pvalue of [tex]1 - \frac{0.02}{2} = 0.99[/tex], so [tex]Z = 2.327[/tex].
How large of a sample size is required?
A sample size of n is required, and n is found when M = 0.035. So
[tex]M = z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]
[tex]0.035 = 2.327\sqrt{\frac{0.42*0.58}{n}}[/tex]
[tex]0.035\sqrt{n} = 2.327\sqrt{0.42*0.58}[/tex]
[tex]\sqrt{n} = \frac{2.327\sqrt{0.42*0.58}}{0.035}[/tex]
[tex](\sqrt{n})^2 = (\frac{2.327\sqrt{0.42*0.58}}{0.035})^2[/tex]
[tex]n = 1076.8[/tex]
Rounding up:
A sample of 1077 is required.

6*10=60+40=100
100[tex]\geq[/tex]100
Answer:
C
Step-by-step explanation:
In order to graph we must first simplify the inequality
40 + 10x ≥ 100
step 1 subtract 40 from each side
40 - 40 cancels out
100 - 40 = 60
we now have 10x ≥ 60
step 2 divide each side by 10
10x/10 = x
60 / 10 = 6
we're left with x ≥ 6
Now to graph
We will start with a closed circled on 6 and because the inequality sign is facing the varibale (x) the line will go in the direction of the right
Thus, the answer is C

-180 minus given value (43)
180-43= 137
(4x+1)= 137
- get x by itself
4x+1=137
4x=137-1
4x= 136
x= 136/4
ANSWER: x=34
Answer:
x= 34
Step-by-step explanation:
(4x + 1 )° + 43° = 180° (due to linear pair)
4x+1+43 = 180
4x + 44 = 180
4x = 180 - 44
4x = 136
x = 136 ÷ 4
therefore, x = 34

How much money is in the account after 17 years?
Answers
Answer:
$[tex]$78760.00[/tex]
Step-by-step explanation:
You want to calculate the interest on $40000 at 5.7% interest per year after 17 years.
The formula we'll use for this is the simple interest formula, or:
[tex]I=P*r*t[/tex]
Where:
P is principal amount, $40,000r is the interest rate, 5.7% per year, or in decimal form, [tex]\frac{5.7}{100} =0.057[/tex]t is the time involved, 17 yearsTo find the simple interest we multiply [tex]40000*0.057*17[/tex] to get
The interest rate is $38,760
Usually now, the interest is added onto the principal to figure some new amount after 17 years.
or 40000.00 + 38760.00 = 78760.00
=$78,760

When money is spent on goods and services, those who receive the money also spend some of it. The people receiving some of the twice-spent money will spend some of that, and so on. Economists call this chain reaction the multiplier effect. In a hypothetical isolated community, the local government begins the process by spending D dollars. Suppose that each recipient of spent money spends 100c% and saves 100s% of the money that he or she receives. The values c and s are called the marginal propensity to consume and the marginal propensity to save and, of course, course, c + s = 1. Let Sn be the total spending that has been generated after n transactions.
Required:
Find an equation for Sn.
Answers
Solution :
If [tex]S_n[/tex] is the total spending generated after n transactions, then [tex]a_n[/tex] is the spending generated during the n-th transaction. Since the government spends D dollars, then [tex]a_1[/tex] = D.
Then the second person will receive D dollars and spend [tex]D_c[/tex] dollars. Therefore, [tex]a_2=D_c[/tex]. The next person will receive [tex]D_c[/tex] dollars, which means they are spending [tex]a_3 = (D_c)c = Dc^2[/tex] dollars. Therefore,
[tex]a_1 = D[/tex]
[tex]a_2=D_c[/tex]
[tex]a_3 = Dc^2[/tex]
[tex]a_4 = (Dc^2)c= Dc^3[/tex]
....
[tex]a_n=Dc^{n-1}[/tex]
∴ [tex]S_n=a_1+a_2+a_3+....+a_n[/tex]
[tex]S_n = D+Dc+Dc^2+Dc^3+...+Dc^{n-1}[/tex]
[tex]S_n= D(1+c+c^2+...+c^{n-1})[/tex]

D. 47 14 cm
Answers
Answer:
D
Step-by-step explanation:
you use the Pythagorean theorem
It states that the area of the square whose side is the hypotenuse is equal to the sum of the areas of the squares on the other two sides.
so mathematically
a2+b2=c2
a and b being the short sides and C being the Hypotenuse
so in our case
a= 10 cm
b= ?
c= 18
a2+b2=c2
(10cm)2+(b)2=(18cm)2
100cm2+b2=324cm2
b2=324cm2-100cm2
b2=224cm2
*putting both sides under a square root*
b=4sqrt14cm

A motor cycle purchased for $9,000 today will be worth 6% less each year. For what can you expect to sell the motorcycle at the end of 5years
Answers
Answer:
$5,956.2
Step-by-step explanation:
First we need to find the amount after 5years using the formula
A =P(1+r)^n
A = 9000(1+0.06)^5
A = 9000(1.06)^5
A = 9000(1.3382)
A = 12,043.8
Interest after 5 years = 12,043.8 - 9000
Interest after 5 years = 3,043.8
Since it will be worth 6% less each year, the amount after 5years will be 9000 - 3,043.8 = $5,956.2

An oil tank has to be drained for maintenance. The tank is shaped like a cylinder that is 3.5 ft long with a diameter of 1.8 ft. Suppose oil is drained at a rate of
1.7 n' per minute. If the tank starts completely full, how many minutes will it take to empty the tank?
Use the value 3.14 for at, and round your answer to the nearest minute. Do not round any intermediate computations.
Answers
Answer:
5 minutes
Step-by-step explanation:
Volume of cylinder = πr²h
Radius, r = diameter / 2 = 1.8 /2 = 0.9
Volume of cylinder = 3.14 * 0.9² * 3.5
Volume = 8.9019 feet³
Drain rate = 1.7 ft per minute
Volume / drain rate
8.9019 / 1.7
= 5.2364117
= 5 minutes (nearest minute)
