Answer:
The confidence interval for the population proportion p is between ( 0.165 and 0.335 )
Hence, Option a) 0.165 and 0.335 is the correct answer.
Step-by-step explanation:
Given the data in the question;
sample size n = 100
sample proportion p₀ = 0.25
q₀ = 1 - p₀ = 1 - 0.25 = 0.75
confidence interval = 95%
First we calculate our Standard Error
Standard Error = √( ( p₀ × q₀ ) / n )
we substitute
Standard Error = √( ( 0.25 × 0.75 ) / 100 )
Standard Error = √( 0.1875 / 100 )
Standard Error = √0.001875
Standard Error = 0.0433
Now, For 95% confidence interval; z = 1.96
so confidence interval for the population proportion p will be;
⇒ p₀ ± ( z × Standard Error )
we substitute
⇒ 0.25 ± ( 1.96 × 0.0433 )
⇒ 0.25 ± 0.084868
⇒ ( 0.25 - 0.084868 ), (0.25 + 0.084868 )
⇒ ( 0.25 - 0.084868 ), (0.25 + 0.084868 )
⇒ ( 0.165, 0.335 )
Therefore, The confidence interval for the population proportion p is between ( 0.165 and 0.335 )
Hence, Option a) 0.165 and 0.335 is the correct answer.

Slove for the value of m
Answer:
m = 6
Step-by-step explanation:
(8m+4) + 38 = 90 ( since they are complementary angles )
8m + 42 = 90
8m = 90 - 42
m = 48/8
m = 6
Answer:
38+8m+4=90 degree(being perpendicular)
42+8m=90
8m=90-42
m=48/8
m=6

The last five houses built in town sold for the prices shown below. Find the mean price. Use pencil and paper. If a new house built in the town sold for $160,000, how would that affect the mean?
prices: $181,00; $187,00; $144,00; $176,00; $175,00
what is the mean price of the houses??
Answer:
172,600
Step-by-step explanation:
hii so basically the mean is the same as average so add all together and divide by how many prices in this case there originally were
so 181,000+187,000+144,000+176,000+175,000=863,000
then divide by 5
863,000/5=172,600

A child’s shoe box measures 4" by 6" by 3". What is the longest pencil you could fit into this box?
Answer:
5in
Step-by-step explanation:
Given data
Lenght= 4 in
Width= 6 in
Height= 3 in
Applying the Pythagoras theorem,
Let the longest pencil that could fit in be z
z^2= l^2+ h^2
z^2= 4^2+ 3^2
z^2= 16+9
z^2= 25
z= √25
z= 5 in
Hence the longest pencil is 5in

Answer:
If in rectangular coordinates we have a point (x, y), then the angle defined between the x-axis and a ray that connects the point with the origin is defined by:
Tan(θ) = y/x
Cos(θ) = x/(√(x^2 + y^2))
Sin(θ) = y/(√(x^2 + y^2))
Ctg(θ) = x/y
Sec(θ) = √(x^2 + y^2)/x
Csc(θ) = √(x^2 + y^2)/y
Ok, now we have all the equations.
We know that:
Sec(C) = 30/24
Then:
√(x^2 + y^2) = 30
x = 24
Replacing x in the first equation we get:
√(24^2 + y^2) = 30
y = √(30^2 - 24^2) = 18
Then we have:
x = 24
y = 18
√(x^2 + y^2) = 30
So we can just replace these in the equations:
Tan(C) = y/x = 18/24
Cos(C) = x/(√(x^2 + y^2)) = 24/30
Sin(C) = y/(√(x^2 + y^2)) = 18/30
Ctg(θ) = x/y = 24/18
Sec(θ) = √(x^2 + y^2)/x = 30/24
Csc(θ) = √(x^2 + y^2)/y = 30/18
Which of the following points represent the zeroes of the function y=x^2+9

a candy machine holds 500 pieces of candy, 20%, percent of which are blue. customers get an srs of 4 pieces of candy per purchase from this machine. let b, equals the number of blue candies a customer gets in a purchase from a full machine. which of the following would find p(b=1)?
Answer:
p(b = 1) = 0.4096 = 40.96%
Step-by-step explanation:
For each candy, there are only two possible outcomes. Either it is blue, or it is not. The probability of a candy being blue is independent of any other candy. This means that the binomial probability distribution is used to solve this question.
Binomial probability distribution
The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
In which [tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.
[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]
And p is the probability of X happening.
20% are blue
This means that [tex]p = 0.2[/tex]
Sample of 4
This means that [tex]n = 4[/tex].
Which of the following would find p(b=1)?
P(X = 1). So
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
[tex]P(X = 1) = C_{4,1}.(0.2)^{1}.(0.8)^{3} = 0.4096[/tex]
So, p(b = 1) = 0.4096 = 40.96%

What value of x satisfies this equation?
log(2x)=2
Answer:
[tex] log(2x) = 2 \\ 2x = {10}^{2} \\ 2x = 100 \\ x = 50[/tex]
The value of x that satisfies this equation log(2x) = 2 is 50
How to determine the value of x?The equation is given as:
log(2x) = 2
Change the equation to an exponential equation
2x = 10^2
Evaluate the exponent
2x = 100
Divide both sides by 2
x = 50
Hence, the value of x that satisfies this equation log(2x) = 2 is 50

(4w-3)^2
what would be the answer to that?? please explain, i’m so confused.
Answer:
16w^2 - 24w + 9
Step-by-step explanation:
To simplify this, you would use the special product (a - b)^2 = a^2 - 2ab + b^2. We can correlate this with the given term so that,
a = 4w
and
b = 3
Now we just substitute into a^2 - 2ab + b^2
(4w)^2 - 2(4w)(3) + (3)^2
16w^2 - 24w + 9
==========================================================
Explanation:
(4w-3)^2 is the same as (4w-3)(4w-3) because squaring something is the same as multiplying it by itself.
Another example would be something like 7^2 = 7*7
-----------
So we're asked to expand out (4w-3)(4w-3)
Let's make x = 4w-3 and replace that first copy of '4w-3' with 'x'
We get this expression: x(4w-3)
Distribute the x through to get...
x(4w-3)
x*4w + x*(-3)
4wx - 3x
-------------
Now replace the x with (4w-3) and apply distribution twice more
4wx - 3x
4w(4w-3) - 3(4w-3)
16w^2 - 12w - 12w + 9
16w^2 - 24w + 9 which is the answer
-------------
You can use the FOIL rule as an alternative method to get this answer. The box method is a visual tool to keep all the terms organized. See the attached image below for what I mean by the box method. The four terms inside the boxes represent the four terms from 16w^2 - 12w - 12w + 9, which was the second to last step we got shown above.
Yet another alternative you could use is the perfect square formula which is
(a-b)^2 = a^2 - 2ab + b^2
where in this case, a = 4w and b = 3.
