Which driver do you predict will win the next drag race?

Answers

Answer 1

The driver that is predict to win the next drag race will be A. Driver A had a mean race time of 3.81 seconds and a standard deviation of 0.21 seconds.

What is standard deviation?

The standard deviation is a statistic that expresses how much variance or dispersion there is in a group of numbers. While a high standard deviation implies that the values are dispersed over a wider range, a low standard deviation shows that the values tend to be close to the mean of the collection.

Given that we are aware that standard deviations indicate variability in a data collection, the variability is greater the higher the standard deviations.

In this case, A has the higher standard deviation. Therefore, the driver that is predict to win the next drag race will be Driver A had a mean race time of 3.81 seconds and a standard deviation of 0.21 seconds.

Find the area of the semicircle. (Take pi=22/7) Diameter=14

Answers

Area of semicircle is 77.

What is semicircle?

A semicircle is defined as half circle formed by cutting the circle into two halves.

Given that;

Diameter of semicircle = 14

Radius of semicircle = 14/2 = 7

Now, Area of semicircle = 1/2 (πr²)

Substitute π = 22/7 and r = 7, we get;

Area of semicircle = 1/2 (πr²)

                             = 1/2 × (22/7) × 7 × 7

If m∠3 = 4x + 10 and m∠4 = 5x, find x.

Answers

The value of x is 10.

Given m∠3 = 4x+10 and m∠4 = 5x

Now, we need to determine what value of x it is.

We know that in quadrilateral four angles are there in that two angles are equal it is said to be as Rhombus.

Two angles are given in this question. We assume those are equal angles.

∴ m∠3 = m∠4

By substituting the values of two angles, we get

4x+10 = 5x

By deducting '4x' on both sides, we get

4x+10-4x = 5x - 4x

10 = x

∴ x = 10

The final value for x is 10.

The value of the angle  x is 108 degree.

According to the statement

We have to find that the value of the x in the adjacent angle.

So, For this purpose, we know that the

The adjacent angles is the two angles are said to be adjacent angles when they share the common vertex and side.

From the given information:

When we extend line AB to E

Then ∠EBC is created

Since BC is parallel to AD

So, ∠EBC =∠BAD = x° (corresponding angles are equal )

Linear pair : Two angles are said to be linear if they're adjacent angles formed by two intersecting lines. The measure of a angular unit is 180 degrees, so a linear pair of angles must add up to 180 degrees.

Now With the linear pair property

x+(x-36) = 180

2x - 36 = 180

2x  = 180+36

2x = 216

x = 216/2

x = 108.

Then one angle is of 108 degree and second angle is 72 degree.

So, The value of the angle  x is 108 degree.

Ultimately, the two triangles; CBD and ∆CAE are congruent since all three angle measures are the same in the triangles.

The corresponding angles in discuss is due to the fact that the lines ED and AE are parallel lines.

5. Also, upon establishing the congruence of the two triangles, it follows that the ratio of their corresponding sides is same for all three sides.

Answers

The area of the rectangular arena can be represented as A = (8y2 - 18y) square feet.

Here, we are given the dimensions of a rectangular arena, which are as follows-

Length = 4y - 9 feet

width = 2y feet

The area of a rectangle is given by the formula-

Area of a rectangle = length x breadth

Thus, in this case, area (A) can be calculated as follows

A = (4y - 9) * 2y

Now, we simplify the equation-

A = (4y)(2y) - 9(2y)

A = 8 - 18y

Thus, the area of the rectangular arena can be represented by the following equation- A = (8 - 18y) square feet.
