A random sample of 400 CLU students is taken. 395 students reported that Econ 311 was their favorite class. Calculate the margin of error for a 96% confidence interval.
Answer:
The margin of error for a 96% confidence interval is of 0.0114 = 1.14%.
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 given by:
[tex]M = z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]
For this problem, we have that:
[tex]n = 400, p = \frac{395}{400} = 0.9875[/tex]
96% confidence level
So [tex]\alpha = 0.04[/tex], z is the value of Z that has a pvalue of [tex]1 - \frac{0.04}{2} = 0.98[/tex], so [tex]Z = 2.056[/tex].
Calculate the margin of error for a 96% confidence interval.
[tex]M = z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]
[tex]M = 2.056\sqrt{\frac{0.9875(0.0125)}{400}}[/tex]
[tex]M = 0.0114[/tex]
The margin of error for a 96% confidence interval is of 0.0114 = 1.14%.

Answer: x = 32°
Step-by-step explanation:
(3x - 4) + (3x - 8) = 180
3x - 4 + 3x - 8 = 180
6x - 12 = 180
6x - 12 + 12 = 180 + 12
6x = 192
6x ÷ 6 = 192 ÷6
x = 32

32 athletes are going camping for the weekend. Three athletes can sleep in one tent. What is the minimum number of tents that will be needed?
Minimum number of tents are 11.
Here,
32 athletes are going camping for the weekend.
3 athletes can sleep in one tent.
We have to find the minimum number of tents.
What is Number system?
A system of writing to express number is called Number system.
Now,
Number of athletes = 32
Number of athletes in one tent = 3
Hence, Minimum number of tents = 32 ÷ 3
We get 11 tents for 32 athletes.
Therefore, Minimum number of tents are 11.

The volume of a cylinder can be found by multiplying the area of its base by its height. A cylinder is 10 inches tall and has a volume that is less than 400 cubic inches. Which inequality can be used to determine the base area, B, of the cylinder?
StartFraction B Over 10 EndFraction greater-than 400
StartFraction B Over 10 EndFraction less-than 400
10 B greater-than 400
10 B less-than 400
WILL RATE BRAINLY
Answer:
B < 400/10
Step-by-step explanation:
The volume of a cylinder is the Area of the base (B) times the height
V(c) = B*h h 0 10 in then V(c) = 10*B
if volume as problem statement is less than 400 in³ then the inequality is:
10*B < 400
B < 400/10

Answer:
x=3
Step-by-step explanation:
15+17+5x = 47
if you add 15 and 17 just to make it easier, you get....
32+5x = 47
what I did next was minus 32 from each side.
so you are left with....
5x = 15
divide each side by 5 and you get
x = 3
you can go back and make sure that- that is right by doing 15+17=32 and
5x3 = 15 then add them together, 32+15 = 47
give answer to d - 4 = 19 d=15
Answer:
Step-by-step explanation:
d-4=19d=15
We move all terms to the left:
d-4-(19d)=0
We add all the numbers together, and all the variables
-18d-4=0
We move all terms containing d to the left, all other terms to the right
-18d=4
d=4/-18
d=-2/9

Qualitative is _______. Select the correct answer below: the type of quantitative data that is the result of measuring the type of quantitative data that is the result of counting a number that is used to represent a population characteristic and that generally cannot be determined easily an attribute whose value is indicated by a label
Answer:
D. an attribute whose value is indicated by a label.
Step-by-step explanation:
In Mathematics, a random variable can be defined as any variable whose values are determined by the outcome of a random experiment.
Basically, random variables are classified into two (2) main categories and these are;
I. Quantitative random variable: these are variables that are numerical in nature. For example, the value of a fair die, number of sweets in a jar, number of eggs in a crate etc.
II. Qualitative random variable: these includes variables that are non-numerical in nature i.e they are categorical. For example, the color of a car, gender, shapes etc.
Hence, qualitative can be defined as an attribute whose value is indicated by a label.
Write an expression that has three terms, two diffrent variables, and one constant.
Answer:
x + y + 1
or
xy + y² + 2
or
x² + y² - 1
or
a²b + b³ + 3
Step-by-step explanation:
You can use x and y as the two variables. Then add them to make is x + y (this is already two variables and two terms). Add a constant, say 1. So x + y + 1, now we have three terms with two different variables and one constant.
Or you can also make it xy + y² + 2 or x² + y² - 1 by adding exponents to each of the variable.
You can choose one from the above or you can make your own (it depends on you).

A housefly can fly about 6.4 feet per second. At this rate, how far can it fly in
25 seconds ?
Answer:
1 second = 6.4 feet
25 seconds = 6.4 * 25 = 160 feet
Answer:
160ft
Step-by-step explanation:
So we already know the unit rate, all we need to do is find how many times the fly can go 6.4 feet in 25 seconds, so our equation is:
25 x 6.4 = 160
So our housefly can fly 160 feet in 25 seconds
