Answer:
D
Step-by-step explanation:
We are given:
[tex]\displaystyle \sqrt{\sqrt[3]{2}}[/tex]
Recall the property:
[tex]\displaystyle \sqrt[b]{x}=x^{1/b}[/tex]
Hence:
[tex]\displaystyle \sqrt{\sqrt[3]{2}}=\sqrt{2^{1/3}}[/tex]
Using the same property:
[tex]\sqrt{2^{1/3}}=(2^{1/3})^{1/2}[/tex]
Recall the property:
[tex](x^a)^b=x^{ab}[/tex]
Hence, multiply:
[tex](2^{1/3})^{1/2}=2^{1/6}[/tex]
Therefore:
[tex]\displaystyle \sqrt{\sqrt[3]{2}}=2^{1/6}[/tex]
Our answer is D.
Answer:
The answer is [tex]2^{\frac{1}{6} }[/tex].
Step-by-step explanation:
To find which answer is equal to [tex]\sqrt{} \sqrt[3]{2}[/tex], start by simplifying [tex]\sqrt{} \sqrt[3]{2}[/tex]. The radical will simplify to [tex]\sqrt[6]{2}[/tex].
An easy way to determine which answer is correct, convert each of the numbers to decimal form.
For [tex]\sqrt[6]{2}[/tex], it will look like 1.122 in decimal form.
For [tex]2^{\frac{2}{3} }[/tex], it will look like 1.587 in decimal form.
For [tex]2^{\frac{3}{2} }[/tex], it will look like 2.828 in decimal form.
For [tex]2^{\frac{1}{3} }[/tex], it will look like 1.260 in decimal form.
For [tex]2^{\frac{1}{6} }[/tex], it will look like 1.122 in decimal form.
Then, by seeing which two decimal forms are the same, it causes the answer to be [tex]2^{\frac{1}{6} }[/tex].

A scatter plot is shown with the title Jordans Hot Chocolate Sales. The x axis is labeled High Temperature and the y axis is labeled Cups of Hot Chocolate Sold. Data points are located at 20 and 20, 30 and 18, 40 and 20, 35 and 15, 50 and 20, 45 and 20, 60 and 14, 65 and 18, 80 and 10, 70 and 8, 40 and 2.
Answers
Answer:
First Part;
As the temperature in the city increases, the number of cups of hot chocolate sold decreases
Second Part;
The approximate value of the slope in number of cups sold per change in temperature is -0.12222
The approximate value of the y-intercept is 20.944 degrees temperature
Step-by-step explanation:
Question;
First Part
What is the relationship between temperature in the city and the number of cups of hot chocolate sold, using your own words
Second Part
How can the line of best fit be made. Give the approximate values of the slope and the y-intercept of the line of best fit
Explanation
The data points are presented in the following table;
[tex]\begin{array}{lcl}x&&y\\20&&20\\30&&18\\40&&20\\35&&15\\50&&20\\45&&20\\60&&14\\65&&18\\80&&10\\70&&8\\40&&2\end{array}[/tex]
A scatter plot is formed from the given data using MS Excel
First part;
From the values of the number of cups sold, y, and the temperature at which they are sold, x, there is correlation between the x and y values, such that as the temperature increases, the number of cups sold decreases, the becomes more rapid as the temperature increases past 50, such that the reason for taking the hot chocolate decreases with increasing temperature
Second Part;
The line of best fit can be found using the least squares regression formula to draw a straight line from the regression equation as follows;
y = a + b·x
[tex]b = \dfrac{\sum \left(x_i - \bar x\right) \times \left(y_i - \bar y\right) }{\sum \left(x_i - \bar x\right )^2 }[/tex]
a = [tex]\bar y[/tex] - b·[tex]\bar x[/tex]
Where;
b = The slope
a = The y-intercept
From MS Excel, we have;
[tex]\bar y[/tex] = 15, [tex]\bar x[/tex] = 48.63636
[tex]\sum \left(x_i - \bar x\right) \times \left(y_i - \bar y\right) = -410[/tex]
[tex]\sum \left(x_i - \bar x\right )^2 = 3354.545[/tex]
Therefore;
[tex]b = \dfrac{-410}{3354.545} = -0.12222[/tex]
The approximate value of the slope, b = -0.12222 (number of cups sold per unit change in temperature)
a = 15 - (-0.12222)×48.63636 ≈ 20.944
The approximate value of the y-intercept, a = 20.944 (in degrees of temperature).

Answer:
Step-by-step explanation:
3x + 4 + 8x + 4 = 140 degree (sum of two interior opposite angle is equal to the exterior angle formed)
11x + 8 = 140
x = 140 - 8
x = 132 /11
x = 12
angle S = 3x + 4
=3*12 + 4
=36 + 4

The radius of a circle with center O is DO. Therefore, option B is the correct answer.
Given that, a circle, with center O, represents a radius of the circle.
What is the circle?A circle is a two-dimensional figure formed by a set of points that are at a constant or at a fixed distance (radius) from a fixed point (center) on the plane. The fixed point is called the origin or center of the circle and the fixed distance of the points from the origin is called the radius.
Radius of a circle is the distance from the center of the circle to any point on it's circumference.
Here, DO and OC is the radius of a circle with center O.
The radius of a circle with center O is DO. Therefore, option B is the correct answer.
