The widest confidence interval that will be produced the 99.7%, given a sample proportion of 0.4.
How to calculate a confidence interval for the population mean?If the sample size is given to be n < 30, then for finding the confidence interval for the mean of the population from this small sample, we use the t-statistic.
Let the sample mean given as [tex]\overline{x}[/tex] and
The sample standard deviation s, and
The sample size = n, and
The level of significance = [tex]\alpha[/tex]
Then, we get the confidence interval in between the limits
[tex]\overline{x} \pm t_{\alpha/2}\times \dfrac{s}{\sqrt{n}}[/tex]
where [tex]t_{\alpha/2}[/tex] is the critical value of 't' that can be found online or from tabulated values of critical value for a specific level of significance and degree of freedom n - 1.
In statistics, a confidence interval is a range to estimate for unknown terms. The most common level is the 95% confidence interval.
So, the widest confidence interval that will be produced the 99.7%, given a sample proportion of 0.4.

Solve for f: 6f + 9g = 3g + f
f = f equals StartFraction negative 8 g Over 3 EndFraction.
f = f equals StartFraction negative 6 g Over 5 EndFraction.
f = f equals StartFraction negative 5 g Over 6 EndFraction.
f = f equals StartFraction 12 g Over 7 EndFraction.
Answer:
f = -6g/5
Step-by-step explanation:
6f + 9g = 3g + f
combine like terms
6f -f = 3g - 9g
5f = -6g
divide both sides of the equation by 5

What is the 5th term of this sequence?
A. 4,800
B. 1,600
C. 6,400
D. 3,200
Answer:
the answer is
Step-by-step explanation:
replace n with 5 and you got 3200
The 5th term of the sequence is 3200 therefore the correct option is option D.
SequenceA sequence is a collection of numbers (or other items such as geometric objects) that follow a pattern or function.
How to find 5th term of this sequence?The function for a sequence is f(n) [tex]=200\times2^{n-1}[/tex]
Where n represents the term.
So for the 5th term

Point S is located at (-9. 8). Point G is located at (-3. 3). Determine the
slope-intercept equation of line SG.
Please help :)
Answer:
y = - [tex]\frac{5}{6}[/tex] x + [tex]\frac{1}{2}[/tex]
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = S (- 9, 8) and (x₂, y₂ ) = G (- 3, 3)
m = [tex]\frac{3-8}{-3+9}[/tex] = - [tex]\frac{5}{6}[/tex] , then
y = - [tex]\frac{5}{6}[/tex] x + c ← is the partial equation
To find c substitute either of the 2 points into the partial equation
Using (- 3, 3 ), then
3 = [tex]\frac{5}{2}[/tex] + c ⇒ c = 3 - [tex]\frac{5}{2}[/tex] = [tex]\frac{1}{2}[/tex]
y = - [tex]\frac{5}{6}[/tex] x + [tex]\frac{1}{2}[/tex] ← equation of line

The sum of the angles in a hexagon is 720°.
a. Write an equation that can be used to determine the value of x.
b. Solve your equation algebraically
c. Determine the measure of angle c.
Given:
The sum of the angles in a hexagon is 720°.
[tex]m\angle A=90^\circ,m\angle B=126.87^\circ,m\angle C=(3x)^\circ,m\angle D=90^\circ, m\angle E=143.13^\circ, m\angle F=143.13^\circ.[/tex]
To find:
(a) Equation to solve the value of x.
(b) The value of x.
(c) The measure of angle C.
Solution:
(a)
We have,
[tex]m\angle A=90^\circ,m\angle B=126.87^\circ,m\angle C=(3x)^\circ,m\angle D=90^\circ, m\angle E=143.13^\circ, m\angle F=143.13^\circ.[/tex]
The sum of the angles in a hexagon is 720°.
[tex]m\angle A+m\angle B+m\angle C+m\angle D+m\angle E+m\angle F =270^\circ[/tex]
[tex]90^\circ+126.87^\circ+(3x)^\circ+90^\circ+143.13^\circ+143.13^\circ =270^\circ[/tex]
[tex]90+126.87+(3x)+90+143.13+143.13 =720[/tex]
Therefore, the required equation is [tex]90+126.87+(3x)+90+143.13+143.13 =720[/tex].
(b)
On solving the above equation, we get
[tex]593.13+3x =720[/tex]
[tex]3x =720-593.13[/tex]
[tex]3x =126.87[/tex]
Divide both sides by 3.
[tex]x =\dfrac{126.87}{3}[/tex]
[tex]x =42.29[/tex]
Therefore, the value of x is 42.29.
(c)
We need to find the measure of angle C.
[tex]m\angle C=(3x)^\circ[/tex]
[tex]m\angle C=(3\times 42.29)^\circ[/tex]
[tex]m\angle C=126.87^\circ[/tex]
Therefore, the measure of angle C is 126.87 degrees.

Step-by-step explanation:
Since we are given triangle PQR is similar to triangle PTU, we can write a proportion to connect the side lengths:
PQ / PT = QR / TU = PR / PU
We don't really care about QR and TU because the are irrelevant to the problem, so we can remove them:
PQ / PT = PR / PU
Now, we can substitute the values given by the diagram:
70 / 30 = 49 / (x + 10)
We can cross multiply,
70(x + 10) = 30 * 49
And divide by 70 on both sides(too lazy to multiply :P)
x + 10 = 3 * 7
x + 10 = 21
x = 11
bag of candy contains 4 strawberry
flavored gumdrops, and 5 orange
flavored gumdrops. If Billy reaches in,
takes one out and eats it, and then 20
minutes later selects another and eats
that one as well, what is the probability
that they were both orange flavored
gumdrops? Leave answer as a fraction in simplest form.
There are 9 candies in total, with 5 being orange. Think of it. For the first grab, you have a 5/9 chance of it being orange flavored. Now there are 4 orange flavored candies, and 8 total candies in the bag. Grabbing a second candy, Billy has a 4/8 chance of grabbing an orange flavored candy. So your two fractions are...
5/9, 4/8
Can you combine these two fractions for a final answer?

A flower box is 3 ft. Long, 2 3/4 ft. Wide, and 1/2 ft. Deep. How many cubic feet of dirt can it hold? A. 4 1/8 B. 5 3/4 C. 6 1/2 D. 6 3/8
Answer:
The box can hold 4 1/8 cubic feet of dirt
Step-by-step explanation:
What we simply have to find here is the volume of dirt it can take
To get this, we have to multiply the dimensions of the box
We have this as follows
Volume or box = length * width * height
Volume of box = 2 3/4 * 1/2 * 3
Volume of box = 11/4 * 3 * 1/2 = 33/8 = 4 1/8 cubic feet

The First Three Terms Of A Sequence Are Given. Round To The Nearest Thousandth (If Necessary). 403,395, 387, . Find The 36Th Term.
Answer:The 36Th Term is 683
Step-by-step explanation:
The nth term of an Ap Is given as
an = a1 + (n - 1 ) d.
Now the first term a1=403
and the common difference,d=403-395=8
The 36th term will now be
a₃₆ = a1 + (n - 1 ) d
a₃₆ = 403 + (36 - 1 ) 8
a₃₆ = 403 + (35 ) 8
a₃₆ = 403 +280
a₃₆ = 683
