Can anybody help!!!??? Pls

The mean of the data is 16 cm and the absolute mean deviation is 1.4 cm.

Given we have the data set values.

Total number of data set values = 10

to find the mean we need to find the sum of the data set values and then divide it by the total number of data set values.

Therefore, mean = 13₊14₊14₊16₊16₊16₊16₊18₊18₊19 / 10

mean = 160/10

mean = 16 cm

To find the absolute mean deviation we need to find the deviation from the mean, from that the absolute mean deviation.

Data value    Deviation from mean   Absolute mean deviation

13                      13 ₋ 16 = ₋3                        I ₋3 I = 3

14                      14 ₋ 16 = ₋2                        I ₋2 I = 2

14                      14 ₋ 16 = ₋2                        I ₋2 I = 2

16                      16 ₋ 16 = 0                             0

16                      16 ₋ 16 = 0                             0

16                      16 ₋ 16 = 0                             0

16                      16 ₋ 16 = 0                             0

18                      18 ₋ 16 = 2                             2

18                      18 ₋ 16 = 2                             2

19                      19 ₋ 16 = 2                             3

Now the total of the absolute mean deviation is 14

divide it by 10

= 14/10

= 1.4 cm

Hence we get the mean and the absolute mean deviation as 16 cm and 1.4 cm.

Answer:

18,000

Step-by-step explanation:

The total weight of two animals in scientific notation is 1.3 x 10⁴ lbs.

Scientific Notation:

A number is written in scientific notation when a number between 1 and 10 is multiplied by a power of 10.

For example,

650,000,000 can be written in scientific notation as 6.5 ✕ 10⁸.

Given,

The approximate weights of two animals are 4.23 x 10³ lbs. and 8.7 x 10³ lbs.

Here we need to find the total weight of the two animals and we need to write the final answer in scientific notation with the correct number of significant digits.

The total weight of the two animals is calculated as

Total weight = Animal 1 + Animal 2

So,

Total weight = 4.23 x 10³ lbs + 8.7 x 10³ lbs.

Take 10³ lbs as the common term,

Then we get,

Total weight = (4.23 + 8.7) x 10³ lbs.

Total weight = 12.93 x 10³ lbs.

It can we rewritten as,

Total weight = 1.293 x 10⁴ lbs.

When we round off it, then we get,

Total weight = 1.3 x 10⁴ lbs.

Hence, the total weight of the two animals is 1.3 x 10⁴ lbs.

By applying the supplementary angle theorem, the magnitude of angle EBF (m<EBF) is equal to 60°.

A supplementary angle can be defined as two (2) angles or arc whose sum is equal to 180 degrees.

Mathematically, a supplementary angle can be calculated by using this formula:

Q + R = 180

Where:

Q and R are measure of the angles subtended.

Substituting the given parameters into the formula, we have;

m<EBC + m<ABE = 180

3y + 10 + 2y - 20 = 180

5y - 20 = 180

5y = 180 + 20

5y = 200

y = 200/5

y = 40

Now, we can determine the magnitude of angle EBF (m<EBF) based on the given diagram:

m<ABE = m<EBF

m<EBF = 2y - 20

m<EBF = 2(40) - 20

m<EBF = 80 - 20

m<EBF = 60°

When we do Matrix multiplication, we keep these two conditions in mind: 1 The number of columns of the first matrix in the multiplication process must equal the number of rows of the second.

here  number of columns of 1st matrix is not equal to number of rows of 2nd matrix.

To multiply two matrices, we must first determine if the first matrix's number of columns and rows equals the second matrix's number of rows. Then sum all of the results after multiplying each element of the first matrix's column by each element of the second matrix's row.

In dealing with many ideas in linear algebra, matrices are crucial. In mathematics, a matrix is a rectangular array or table with rows and columns of integers, symbols, or expressions. Matrix operations include addition, subtraction, multiplication, and other operations.

The proportion of heads and the proportion of tails p(H) + p(T) = 1.

Let p(H) represent the long-term probability that the coin will land on heads, and p(T) represent the long-term probability that the coin will land on tails.

Keep in mind that we must be at a tail and transition with a probability of 0.5 in order to get a head. So, p(H) = 0.5p(T).

Noting that we can either be at a head and transition to a tail with a probability of 1, or at a tail and transition to a tail with a probability of 0.5, we can obtain a tail. p(T) therefore equals 0.5 * p(T) + p(H).

Note that p(T) = 2 p is the result of the first two equations (H). We obtain p(H) = 1/3 and p(T) = 2/3 by substituting into p(H) + p(T) = 1. So, eventually, we'll have two-thirds of the coins with heads and one-third with tails.

The probability of finding three heads is 1/4. We should find the probability of finding three heads in five tosses with the help of the following formula:

p(x) = (x+1) C x-1 p(3 Heads)

p(x) = (5+1) C 4 -1p(3 Heads) = 7/8.

Step-by-step explanation:

67.89 is a terminating decimal, so it is a rational number.

The equation illustrates that the number of miles will be 3 miles.

The taxi company charged a pick- up fee of $2.90 plus $1.25 per mile.

Let the number of miles be m.

Therefore, this will be:

2.90 + (1.25 × m) = 6.65

2.90 + 1.25m = 6.65

Collect like terms

1.25m = 6.65 - 2.90

1.25m = 3.75

m = 3.75/1.25

m = 3

The number of miles is 3 miles.

The equation of the parabola in vertex form is y=-2(x-4)²+4.

Given that the vertex point is (4,4), (3,2).

The equation of a parabola in vertex form is y=a(x-h)²+k where a is called stretch coefficient and the point (h,k) is the vertex of the parabola.

A parabola with its vertex at the point (4,4), therefore h=4,k=4 and we can write

y=a(x-4)²+4

To find the value of a we use the point (3,2). Substituting on the equation we get:

y=a(x-4)²+4

2=a(3-2)²+4

2=a(1)²+4

2=a+4

2-4=a

-2=a

Then the equation of the parabola in vertex form is y=-2(x-4)²+4.

Hence, the equation of the parabola in vertex form from the given point (4,4), (3,2) is y=-2(x-4)²+4.

The length of the sum of the smallest value and the largest value is 105 feet.

Given data

BA = x + 30

BC = 2x + 10

CD = x + 20

Perimeter = 120 feet

The perimeter refers to the sum of all the dimensions which is given as 120 feet. We sum the dimensions given to find the value of x.

This is done as follows:

Perimeter = BA + BC +CD

120 = x + 30 + 2x + 10 + x + 20

120 = x + 2x + x + 30 + 10 + 20

120 = 4x + 60

4x = 120 - 60

4x = 60

x = 60 / 4

x = 15

plugging in x = 15 into the dimensions given we have

BA = x + 30

BA = 15 + 30

BA = 45

BC = 2x + 10

BC = 2 * 15 + 10

BC = 30 + 40

BC = 70

CD = x + 20

CD = 15 + 20

CD = 35

Hence we can say that the smallest value is 35 and the largest value is 70.

sum of the values

70 + 35 = 105

The value of 8-√5 is approximately 5.76 which is calculated by rounding the square root of 5 to 2 decimal places.

A number y whose square (the outcome of multiplying the number by itself, or y × y), is x (y² = x) is said to be the square root of a number x.

Now the given expression is of the form ( 8 - √5 )

We know that √5 = 2.2360... ≈ 2.24 (rounded to 2 decimal places.)

∴ 8 - √5

= 8 -  2.24
