Mean is 5.25, Median is 5 and mode is 3.

Given,

In the question:

There are numbers:

3, 4, 5, 7, 6, 8, 8, 5, 3, 6, 4, 5, 3, 3, 7, 7.

To find the mean, median and mode.

Let's Know :

How do you find the mean median and mode?

The mean (average) of a data set is found by adding all numbers in the data set and then dividing by the number of values in the set. The median is the middle value when a data set is ordered from least to greatest. The mode is the number that occurs most often in a data set.

Now, According to the above statement :

To find Mean:

[tex]\frac{3+4+ 5+ 7+ 6+ 8+ 8+ 5+ 3+ 6+ 4+ 5+ 3+ 3+ 7+ 7}{16}[/tex]

= 84/16 = 5.25

For Median

Arrange in ascending order

3, 3, 3, 3, 4,4, 5,5,5, 6,6, 7, 7, 7, 8,8.

There is an even no. of observations. i.e., 16 numbers.

then, there is no single middle value; the median is then usually defined to be the mean of the two middle values: so the median of

Middle two values is : (5 + 5)/2 = 10/2 = 5

Middle value is 5

For Mode:

The mode is the number that occurs most often in a data set.

Mode is 3 .

Hence, Mean is 5.25, Median is 5 and mode is 3.

You have the square QRST, furthermore, you have that sides QS and QU are given by the following algebraic expressions:

QS = 16t - 14

QU = 6t + 11

Due to QRST is a square, the length of all sides are equal.

You can notice by the symmetry of the figure that QS = 2QU

Equal the expressions for QS and 2QU and solvde for t:

16t - 14 = 2(6t + 11) apply distribution property

16t - 14 = 12t + 22 add 14 both sides

16t = 12t + 22 + 14 subtract 12t both sides

16t - 12t = 22 + 14 simplfy like terms

4t = 36 divide by 4 both sides

t = 36/4 simplify the fraction

t = 9

Hence, the value of t is t = 9

The value of ∠L is 2.909° as the definition of angle is "An angle is created by joining two line segments at one point, or we can say that an angle is the combination of two line segments at a common endpoint".

An angle is created by joining two line segments at one point, or we can say that an angle is the combination of two line segments at a common endpoint. When two straight lines or rays intersect at a single endpoint, an angle is created. The vertex of an angle is the location where two points come together. The Latin word "angulus," which means "corner," is where the word "angle" originates. Based on measurement, there are different kinds of angles in geometry. The names of fundamental angles include acute, obtuse, right, straight, reflex, and full rotation. A geometrical shape called an angle is created by joining two rays at their termini. In most cases, an angle is expressed in degrees.

Here,

Side k = 130

Side l = 710

Side m = 833.99204

Angle ∠L = 2.909°

Angle ∠M = 16.091°

Angle ∠K = 161°

Angle L=cos⁻¹((m²+ k² - l²)/2mk)

=cos⁻¹((834²+130²-710²)/2*834*130)

= 2.909°

Since the definition of an angle is "An angle is created by joining two line segments at one point, or we can say that an angle is the combination of two line segments at a common endpoint," the value of ∠L is 2.909°.

The original speed of the train was 32 miles per hour.

We have a train. The train travels a distance equal to 288 miles. It is given that if the speed of a train is increased by 4 miles per hour from its original speed, then it takes 1 hour less to cover the distance. We need to find out the original speed of the train.

Let the original speed of the train be denoted by the variable "s". We can write the following equations using the given data:

s = 288/t

(s + 4) = 288/(t - 1)

We will substitute the value of "s" from the first equation into the second equation.

(288/t) + 4 = 288/(t - 1)

(288)×(t - 1) + 4×t×(t - 1) = 288×t

288t - 288 + 4t² - 4t = 288t

4t² - 4t - 288 = 0

t² - t - 72 = 0

t² - 9t + 8t - 72 = 0

t(t - 9) + 8(t - 9) = 0

(t - 9)(t + 8) = 0

The value of time cannot be negative, so the value of "t" is 9. Now, we will substitute this value into the first equation.

s = 288/t

s = 288/9

s = 32

Hence, the original speed of the train is 32 miles per hour.

The dimensions of the golf hole found using the indicated variable expressions are as follows;

a. The area of the golf hole is 4·x² + 12·x

b. The perimeter of the golf hole is 8·x + 8

c. The perimeter of the golf hole if the area of the hole is 216 square feet is 56 feet

The perimeter of a geometric figure is found by the length of the boundary of the figure.

a. The area of the gulf hole is found as follows;

The area is a composite figure, which consists of a rectangle of length 3·x and width (x + 4) and a square of length x

Which indicates that the area is A = 3·x × (x + 4) + x×x = 3·x² + 12·x + x²

The area of the hole, A = 3·x² + 12·x + x² = 4·x² + 12·x

The area of the hole is A = 4·x² + 12·x

b. The perimeter of the hole is found as follows;

P = (x + 4) + 3·x + (x + 4) + x + x + x = 8·x + 8

The perimeter of the hole = 8·x + 8

c. The area of the golf hole = 216 square feet, which indicates;

4·x² + 12·x = 216

4·x² + 12·x - 216 = 0

x² + 3·x - 54 = 0

(x + 9)·(x - 6) = 0

x = 6 or x = -9

The perimeter of the golf hole is therefore;

P = 8 × 6 + 8 = 56
