The terminal point of the unit circle (cos θ, sine θ) for 30° is ( √3/2 , 1/2 ).
What is the terminal point?"The terminal point is the ray that has been rotated around the origin to form an angle with the stationary ray which is the initial side of the angle. They are sine and cosine values of the most common acute-angle measures".
For the given question,
Angle = 30°
The terminal point on the unit circle has the cosine as x -coordinate and the sine as y - coordinate are mostly acute-angle measures.
Here, θ = 30°
The x-coordinate is cos 30° = [tex]\frac{\sqrt{3} }{2}[/tex]
The y-coordinate is sin 30° = [tex]\frac{1}{2}[/tex]
Hence we can conclude that the terminal point for 30° is ( √3/2 , 1/2).

Answer:
y = (4/7)x + 3
Step-by-step explanation:
rise = 7 - 3 = 4
run = 7 - 0 = 7
slope = rise/run = 4/7
y-intercept = 3
---------------------
Slope intercept form is
y = mx + b
m is the slope = 4/7
b is the y-intercept = 3
the equation is
y = (4/7)x + 3
Phone bills from the residents of the city have a mean of $64 and a standard deviation of $9. Random samples of 100 phone bills are drawn from this
population. Find the mean and standard error of the sampling distribution.
O mean is 6.4: standard error is 9
O mean is 64; standard error is 9
O mean is 6.4: standard error is.9
O mean is 64: standard error is.9
Answers
Answer:
Mean of 64 and standard error of 0.9.
Step-by-step explanation:
Central Limit Theorem
The Central Limit Theorem establishes that, for a normally distributed random variable X, with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]s = \frac{\sigma}{\sqrt{n}}[/tex].
For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.
Phone bills from the residents of the city have a mean of $64 and a standard deviation of $9. Sample of 10.
By the Central Limit Theorem, the mean is 64 and the standard error is [tex]s = \frac{9}{\sqrt{100}} = \frac{9}{10} = 0.9[/tex]
So mean of 64 and standard error of 0.9.

If aₙ = n(a ₙ-₁) and a₁ = 1, what is the value of a₅?
Answers
Answer:
The correct answer is Option c (120).
Step-by-step explanation:
The given value is:
[tex]a_1=1[/tex]
[tex]a_n=n(a_{n-1})[/tex]....(equation)
On putting the value of [tex]a_1[/tex] in the above equation, we get
⇒ [tex]a_2=2(a_{2-1})[/tex]
[tex]=2(a_1)[/tex]
[tex]=2\times 1[/tex]
[tex]=2[/tex]
⇒ [tex]a_3=3(a_{3-1})[/tex]
[tex]=3(a_2)[/tex]
[tex]=3\times 2[/tex]
[tex]=6[/tex]
⇒ [tex]a_4=4(a_{4-1})[/tex]
[tex]=4(a_3)[/tex]
[tex]=4\times 6[/tex]
[tex]=24[/tex]
hence,
⇒ [tex]a_5=5(a_{5-1})[/tex]
[tex]=5(a_4)[/tex]
[tex]=5\times 24[/tex]
[tex]=120[/tex]
Thus the above is the correct solution.

Based on the figure below, find the value of x.
Answers
Answer:
The value of x = 9.Step-by-step explanation:
The figure shown is represented as a right triangle, which means that the sum of the angles within should add up to 90°. So if we take 32° (one of the angles given) and subtract it from 90°, we should be left with 58°.
This means that the value of the equation that contains "x" must equal 58°. Therefore, (6 x 9 + 4)° must equal 58.° Which means that the value of x = 9.
What is the radius of a sphere with a volume of 1203 cm', to the nearest tenth of a
centimeter?
Answers
Answer:
The radius of the sphere is of 6.6 centimeters.
Step-by-step explanation:
Volume of an sphere:
The volume of an sphere of radius r is given by:
[tex]V = \frac{4\pi r^3}{3}[/tex]
In this question:
[tex]V = 1203 \text{cm}^{3}[/tex]
Replacing into the equation, we find the radius, in centimeters. So
[tex]V = \frac{4\pi r^3}{3}[/tex]
[tex]1203 = \frac{4\pi r^3}{3}[/tex]
[tex]r^3 = \frac{1203*3}{4\pi}[/tex]
[tex]r = \sqrt[3]{\frac{1203*3}{4\pi}}[/tex]
[tex]r = 6.6[/tex]
The radius of the sphere is of 6.6 centimeters.

The percentage of historical
From the table, we have:
[tex]Historical = 2[/tex]
and
[tex]Total = 6+3+7+2+7[/tex]
[tex]Total = 25[/tex]
So, the percentage of historical is:
[tex]\%H = \frac{Historical}{Total} * 100\%[/tex]
This gives:
[tex]\%H = \frac{2}{25} * 100\%[/tex]
[tex]\%H = \frac{200\%}{25}[/tex]

Which is a reasonable first step that can be used to solve the equation 4 x + 3 (x + 2) = 5 (2 x minus 3)? Distribute the 3 to x + 2, and distribute the 5 to (2x – 3). Combine 4x and x on the left side of the equation. Apply the subtraction property of equality to move the 2 from the left to the right side of the equation. Apply the addition property of equality to move the 3 from the right to the left side of the equation.

Answer:
Distribute the 3 to x + 2, and distribute the 5 to (2x – 3).
Step-by-step explanation:
Given

Required
Reasonable first step
The reasonable first step is to open the brackets; i.e. distribute 3 to its bracket and 5 to its bracket.
This gives:
[tex]4x + 3(x + 2) = 5(2x - 3)[/tex]
[tex]4x + 3x + 6 = 10x - 15[/tex]
