Answer: 21
Why: 21/2321
Using the concept of a confidence interval, it is that the margin of error in this example is of 2%.
------------------------
A confidence interval for a percentage is written in the following format:
[tex]P \pm M[/tex]
That is, the percentage is of P, plus of minus M points, in which M is the margin of error.
------------------------
In this question, the percentage is 63% plus or minus 2%, thus, the margin of error is of 2%.A similar problem is given at https://brainly.com/question/21496409

Find the cosθ if an angle is in standard position and the point with coordinates (7,24) lies on the terminal side of an angle.
Answer:
0.28
Step-by-step explanation:
Angles in standard position are angles with the initial side on the positive x-axis.
Since (7,24) lies on the terminal side of an angle, hence the line passing through the origin and point (7, 24) forms an angle with the x axis.
The slope of the line passing through the origin (0, 0) and the point (7, 24) is given by:
[tex]slope(m)=\frac{y_2-y_1}{x_2-x_1}\\\\m=\frac{24-0}{7-0}\\\\m=\frac{24}{7 }[/tex]
The angle θ between a straight line and the x axis is:
tanθ = m
where m is the slope of the line.
Let θ be the angle between the line with a slope of 24/7 and the x axis, therefore:
tanθ = 24 / 7
θ = tan⁻¹(24/7)
θ = 73.74°
cosθ = cos(73.74°) = 0.28
Suppose you flip a fair coin
1000 times. What do you think
is the probability of getting
exactly 500 heads?
Answer:
50
Step-by-step explanation:
first estimate probably 50% depends also in luck
Answer:
about 0.02
Step-by-step explanation:
If you toss a coin 1,000 times the average (mean) number of heads equals 500, yet the probability that you will get exactly 500 heads in 1,000 tosses is about 0.02.

Answer:
B is correct.
You got it right =D
Explanation:
B is correct because the graph never goes up after leaving zero, therefore it can never increase. This eliminates options A and D.
If the graph had remained constant, the graph would have been a straight line, therefore eliminating C
With A, C, and D being eliminated, B is the correct answer.

f f(x) is a linear function, which statement must be true? f(x) has no constant term. f(x) has no x2-term. f(x) has no terms with a coefficient other than 1. f(x) has no x-term. Mark this and return
Answer:
f(x) has not x^2 term.
Step-by-step explanation:
Linear function is in the form of y=mx+b
In the linear function y=mx+b there is a constant term b
There is also an x term.
m is the slope of f(x). The value of 'm' can be any number.
If we have x^2 term in f(x) then it is quadratic function.
Linear function must always have x with exponent 1
True option is f(x) has not x^2 term.

Carlos wants to rent a car. For the particular car he wants, Gentle Rental charges $185 per week plus 25 cents per mile driven. Rental Giant charges a flat fee of $275 per week. What is the number of miles driven so that renting from Gentle Rental cost Carlos less than renting from Rental Giant?
A. Less than or equal to 360 miles
B. Less than 360 miles
C. Less than or equal to 115 miles
D. Less than 1,840
Answer:
B. Less than 360 miles
Step-by-step explanation:
Let the number of miles driven be [tex]x[/tex]
The cost of renting from Gentle Rental per week is
[tex]185+0.25x[/tex]
The cost of renting from Rental Giant per week is [tex]275[/tex].
Now we have to find after how many miles the cost of renting from Gentle Rental cost Carlos less than renting from Rental Giant
[tex]185+0.25x<275\\\Rightarrow 0.25x<275-180\\\Rightarrow x<\dfrac{90}{0.25}\\\Rightarrow x<360[/tex]
So, the answer is less than 360 miles.

A coin is tossed and a six-sided die numbered 1 through 6 is rolled. Find the probability of tossing a head and then rolling a number greater than 1.
Answer:
[tex]Probability = 0.4167[/tex]
Step-by-step explanation:
Given
A toss of coin and a roll of 6-sides die
Required
P(Head and Number greater than 1)
First, we list the sample space of the coin:
[tex]Sample\ Space = \{Head, Tail\}[/tex]
From the sample space above:
[tex]P(Head) = \frac{1}{2}[/tex]
Next, we list the sample space of the die:
[tex]Sample\ Space = \{1,2,3,4,5,6\}[/tex]
There are 5 outcomes greater than 1; i.e. 2,3,4,5 and 6.
So:
[tex]P(Outcome> 1) = \frac{5}{6}[/tex]
Lastly, the required probability is calculated as:
[tex]Probability = P(Head) \ and \ P(Outcome>1)[/tex]
Change and to *
[tex]Probability = P(Head) \ * \ P(Outcome>1)[/tex]
Substitute values for P(Head) and P(Outcome > 1)
[tex]Probability = \frac{1}{2} * \frac{5}{6}[/tex]
[tex]Probability = \frac{5}{12}[/tex]
[tex]Probability = 0.4167[/tex]

Solve the equation x/3 -5- y for x.
Answer:
Well first of all, that isn't an equation, I wil however interpret it as best as I can.
x = 25 + 5y
Step-by-step explanation:
x/5 - 5 - y for x, so, x/5 - 5 - y = 0.
Add 5 and y to both sides.x/5 = 5+ y, multiple both sides by 5.
x = 25 + 5y

Answer:
Angle D=162 P=74cm A=340sqcm
need help asap please!
Answer:
(f + g)(3) = 9
Step-by-step explanation:
f(x) = x² + 1
g(x) = x - 4
Thus:
(f + g)(x) = (x² + 1) + (x - 4)
(f + g)(x) = x² + 1 + x - 4
(f + g)(x) = x² + x - 3
Therefore, to find (f + g)(3), plug in the value of 3 into the equation:
(f + g)(3) = (3)² + 3 - 3
(f + g)(3) = 9 + 3 - 3
(f + g)(3) = 9
