The value of the area of the shaded region in the circle is 4π - 8.

A circle is a geometrical figure which becomes by plotting a point around a fixed point by keeping a constant distance.

The longest line which can be drawn inside the circle will be the diameter.

As per the given circle,

By Pythagoras' theorem,

LN = √(4² + 4²) = √32

Radius r = LN/2 = √32/2

Area of shaded region = area of the semicircle - the area of right angle triangle.

A = π(√32/2)²/2 - (1/2) × 4 × 4

A = (32π)/8 - 8

A = 4π - 8

Hence, "The circle's shaded region's area has a value of 4 to 8".

Data points' variance from the mean is a measure of how they vary. A variance, according to Layman, is a measurement of how widely apart a set of data (numbers) are from their mean (average) value.

Finding the expected difference of deviation from the actual number is what is meant by variance. As a result, variance is influenced by the data set's standard deviation.

Data is more dispersed from its mean the higher the variance value, and less dispersed from mean if the variance value is low or minimal. As a result, it is referred to as a measure of data spread from mean.

5 x 3 x 2 = 30

Answer:

$420

Step-by-step explanation:

To find the original price, we need to determine how much the sale price was discounted, and then add that amount back to the sale price. Since the sale price was 68% less than the original price, the discount was 100% - 68% = 32% of the original price.

To find the amount of the discount, we multiply the original price by the discount percentage: 32% * original price = $134.40

Dividing both sides of the equation by the discount percentage gives us the original price: original price = $134.40 / (32% * 1) = $134.40 / 32% = $420.

Therefore, the original price of the sofa was $420.

The size of a region on a planar or curved surface can be expressed mathematically using the idea of area. The term "surface area" refers to the area of an open surface or the perimeter of a three-dimensional object, whereas the term "plane area" refers to the area of a shape or planar lamina.

Here,

Given :

the length of the rectangular house =15.24 m

the width of the rectangular house = 9.1 m

c) To find Shane's overall average number of jumps completed, we need to add up the total number of jumps he completed at each height and divide by the total number of jumps he attempted.

At the lowest height, Shane completed 3 out of 3 jumps, for a total of 3 completed jumps.

At the middle height, Shane completed 5 out of 6 jumps, for a total of 5 completed jumps.

At the highest height, Shane completed 3 out of 4 jumps, for a total of 3 completed jumps.

In total, Shane completed 3 + 5 + 3 = 11 jumps out of a total of 3 + 6 + 4 = 13 jumps attempted.

His overall average number of jumps completed is 11 / 13, or approximately 0.85 jumps.

d) Since Shane's average number of jumps completed is greater than one-half (0.5), the eighth graders should be awarded 50 points

Step-by-step explanation:

For your other question A and B for A Correct! To find the total distance thrown by Claire and Grace, you first converted the mixed numbers 5/8 and 3/5 to fractions with a common denominator (in this case, 40), then added those fractions together to find the total distance in fraction form. Finally, you converted the fraction 49/40 back to a mixed number and added it to the whole number distances thrown by Claire and Grace to find their total distance.

The total distance thrown by Claire and Grace is 82 feet 9/40 inches, or approximately 82.225 feet.                                                                                                               For B also Correct!

the work done by the force F on a particle moving counterclockwise around the closed path C is 9π by integral.

Green's Theorem states that:

∮C F · dr = ∫∫D (∂Q/∂x - ∂P/∂y) dA

Where C is the boundary of the region D, P and Q are the components of the vector field F, and dr is the vector differential along the boundary C.

In this case, the region D is a circle with radius 2, so we can express the boundary C as r = 2 cos θ. We also need to calculate the components of the vector field F. These are P = e^x - 3y and Q = e^y + 6x.

Plugging these values into Green's Theorem, we get integral:

∮C F · dr = ∫∫D (∂Q/∂x - ∂P/∂y) dA

= ∫∫D (e^y + 6 - (-3)) dA

= ∫∫D (e^y + 9) dA

= ∫ 0 2π ∫ 0 2 (e^2 cosθ

The likelihood that a random cumulative variable will fall within a specific range of values rather than taking on a single value is specified by the Probability Density Function.

The probability density function (PDF), also known as the density of a continuous random variable, is a function whose value at any specific sample (or point) in the data point (the range of potential values for the random variable) can be understood as having given a relative likelihood that the value of something similar to the random variable would be closer to that sample.

There is no absolute probability that a random variable will take on any specific value because there are an unlimited number of alternative values to begin with. However, the PDF value at two samples can be used to estimate how much more likely it is for the random variable to have that particular value in any given draw.

The Cantor distribution, which although having no discrete component, does not assign positive probabilities to any specific locations, and discrete random variable probability distributions do not all have a density function.

A distribution has a density function if and only if the cumulative distribution function F(x) is fully continuous. In this case, F is typically always differentiable, and its derivative can be used to symbolize the probability density.
