Answer:

The length of a 180° arc of a unit circle is π ≈ 3.14 units.

Step-by-step explanation:

Use your knowledge of the circumference of a circle (the length full around) and the fact that there are 360° in the central angle of a full circle. The distance around is proportional to the angle, so an arc of measure 180° will have a length equal to

... (180°/360°) × circumference = (1/2)×circumference

For a unit circle, the circumference is 2π (= π×diameter = 2π×radius). Half that length is π units.

Answer:

1/3 ! i think?

Step-by-step explanation:

there's a 1/2 chance it lands on heads and a 2/3 chance it lands on red or blue and 1/2 x 2/3 is 1/3

The probability that the coin flips heads, and the spinner lands on either red or blue is 1 by 3.

Since Leah flips a coin, and then she spins a spinner with 3 equal sections colored red, green, and blue.

Since there is half chance for heads and 2 by 3 for landing on red or blue

So, the probability should be

[tex]= 1/2 \times 2/3 \\\\= 1/3[/tex]

Hence, The probability that the coin flips heads, and the spinner lands on either red or blue is 1 by 3.

you get 8x^12

8 +12 =20

The sum of a and b according to the expression solved is 20.

Expressions in math are mathematical statements that have a minimum of two terms containing numbers or variables, or both, connected by an operator in between.

Given that, the expression (2x⁴)³ was written in axᵇ form,

We will get,

(2x⁴)³ = 8x¹²

Here, a = 8 and b = 12

The sum = 20

Hence, the sum of a and b according to the expression solved is 20.

The word that best describes the degree of overlap between the two data sets is "moderate."

Statistics is the discipline that concerns the collection, organization, analysis, interpretation, and presentation of data.

We have to find the word which  best describes the degree of overlap between the two data sets.

Two line plots with the same scale and interval, from ten to twenty, with tick marks every one unit.

The word that best describes the degree of overlap between the two data sets is "moderate."

The two data sets have some values in common, but there are also some differences between them.

Answer:

150 in^2

Step-by-step explanation:

The surface area, in general, is A = 6s^2, where s is the length of one side of the cube.

If the edge length is 5 in, then the surface area of the cube is

A = 6(5 in)^2 = 6(25 in^2) = 150 in^2

It takes the balloon 0.6 minutes to reach an altitude of 454.6 feet above sea​ level

A linear equation is given by:

y =mx + b

where y, x are variables, m is the slope of the line and b is the y intercept.

Let y represent the altitude of the balloon at time x.

Given that a trend line passes through the point ​(0​,481​) and ​(10,39), the equation of the trend line is:

[tex]y-y_1=\frac{y_2-y_1}{x_2-x_1} (x-x_1)\\\\y-481=\frac{39-481}{10-0}(x-0)\\\\y=-44.2x+481[/tex]

At 454.6 ft:

454.6 = -44.2x + 481

-26.4 = -44.2

t = 0.6 minutes
