The difference between the means is about equal to the mean absolute deviation of the data sets.
The difference between the mean is about 2 times the mean absolute deviation of the data sets.
The difference between the mean is about 4 times the mean absolute deviation of the data sets.
O The difference between the means is about 5 times the mean absolute deviation of the data sets.

Answers

Answer 1

The true statement is, The difference between the mean is about 2 times the mean absolute deviation of the data sets.

Mean absolute deviation (MAD) is defined as the average value of the absolute deviations from the mean.

Difference of the means is found by subtracting the two means.

Each mean is found by adding the data points and then dividing by the number of data sets.

The relationship between the difference of means and the MAD of two sets is,

The difference between the mean is about 2 times the mean absolute deviation of the data sets.

Hence the correct option is B.

The probability that a resident who has only completed high school are aged 30-39 = 0.059

We know that the probability of event A is given by the formula,

P(A) = number of possible outcomes of event A / total number of outcomes

We need to find the probability that a resident who has only completed high school are aged 30-39.

Let event A: a resident who has only completed high school are aged 30-39.

The number of  resident who completed high school and aged 30-39 = 933

And the total nuember of residnts = 15818

Using probability formula the required probability would be,

P(A) = n(A)/n(S)

P(A) = 933/15818

P(A) = 0.059

How to determine an equation of this line?

In Mathematics and Geometry, the point-slope form of a straight line can be calculated by using the following mathematical equation (formula):

y - y₁ = m(x - x₁)

Where:

x and y represent the data points.m represent the slope.

First of all, we would determine the slope of this table;

Slope (m) = (y₂ - y₁)/(x₂ - x₁)

Slope (m) = (300 - 200)/(15 - 10)

Slope (m) = 100/5

Slope (m) = 20

At data point (10, 200) and a slope of 20, a linear equation for this line can be calculated by using the point-slope form as follows:

y - y₁ = m(x - x₁)

y - 200 = 20(x - 10)  

y = 20x - 200 + 200

y = 20x ≡ p = 20h

Making h the subject of formula, we have:

h = p/20

Answers

The probability of picking a 7 and then picking a number greater than 7 is 1/3.

Now, given that we have already picked three cards. So, 7, 8, and 9.

We know that, probability of an event = Number of favourable outcomes/Total number of outcomes.

The number of possible outcomes is 3.

Probability of picking 7 = 1/3

Now, as card seven is already picked up cards 8 and 9 are the only card left.

therefore, the sample size(possible outcomes) was reduced to 2 only.

Also, cards 8 and 9 both are greater than 7, thus the desired outcome is also 2.

Further the probability of the number greater than 7 occurring,

Probability (n>7) = 2/2 =1

Probability picking a number greater than 7

The probability of picking a 7 and then picking a number greater than 7

= Probability of card 7 occuring x probability of card 8 and 9 occurring

What is sine rule?

The sine rule, also known as the law of sines, is a relationship that states that side “a” divided by the sine “a” is equal to side “b” divided by the sine “b”. It can be used to find unknown lengths or angles of a triangle and its formula can be written as Sin A/a

The sine rule states that

a/sinA = b/sinB = c/sinC

To find the value of |BC| using the above formula.

a/sin41 = 20/sin78

a= (20/sin78 ÷sin41)

a = 20* 0.6561 /0.9782

a = 13cm

/BC/ = 13cm

To find |AC| using the same formula

a/sinA = b/sinB = c/sinC

note that <A = 180 - (78+41) = 61

b/sin61 = 13/sin41

b = (13*sin61)/sin41

b = 13* 0.8746/0.6561

b = 17cm

/AC/ = 17cm

To find /DB/ using the same formula

a/sinA = b/sinB = c/sinC

Note that <DCB = 180 - (60+31)  = 180-91 = 89

c/sin89 = 31/sin60

c = 31 / 0.8660 ÷ 0.9998

c = 36cm

/DB/ = 36cm

To find /DC/ using the same formula

a/sinA = b/sinB = c/sinC

b/sin31 = 13/sin60

b = 13*sin60)/sin31

b = 13*0.5150 /0.8660

b = 7.7cm

|DC| = 8cm

To find /ED/ using the same formula

a/sinA = b/sinB = c/sinC

Note that <DCE = 180- (36+15) = 129

Tis implies that

c/sin129 = 8/sin15

c= (8*0.7771)/0.2588

c = 24 cm

To find |EC| using the same formula

a/sinA = b/sinB = c/sinC

d/sin36 = 8/sin15

d*sin15 = 8*sin36

d= (8*sin36)/sin15

d = (8*0.5878)/ 0.2588

d = 18cm

|EC|= 18 cm

Finally, To find |EA| using the cosine  formula

Note that < ECA = 180-78 = 102

c² = a² +e²-2*aecos102

c²= 18²+8²-2*18*8*-0.2079

We have,

The statement that is true about the graph of y = 0.25(2^x).

The coordinates of the y-intercept are (0, 1/4).

We can see this by setting x = 0 in the equation,

which gives,

y = 0.25 x 2^0 = 0.25 x 1 = 1/4.

Therefore, the y-intercept is at (0, 1/4).

The other statements are false:

The graph increases from left to right, since 2^x increases as x increases.

The coordinates of the y-intercept are not (0, 14), but rather (0, 1/4).

There is no vertical asymptote in the graph.

The x-intercept occurs where y = 0, which gives 0.25 * 2^x = 0. Solving for x gives x = -2.

Therefore, the coordinates of the x-intercept are (-2, 0), not (2, 0).

Thus,

The number of miles m (in billions) traveled by vehicles in City A can be modeled by
m = 2.86t + 112 where t is the number of years since 1994. Use a graphing calculator to
approximate the year in which the number of vehicle miles of travel in City A was 140 billion.
Based on the linear model, the number of vehicle miles of travel in City A was 140 billion in the
year

Answers

The value of the year in which the number of vehicle miles of travel in City A was 140 billion is,

t = 9.79 years

Given that;

The number of miles m (in billions) traveled by vehicles in City A can be modeled by,

m = 2.86t + 112

where t is the number of years since 1994.

Hence, We can formulate;

The value of the year in which the number of vehicle miles of travel in City A was 140 billion is,

m = 2.86t + 112

140 = 2.86t + 112

140 - 112 = 2.86t

28 = 2.86t

t = 28/2.86

t = 9.79 years

Thus, The value of the year in which the number of vehicle miles of travel in City A was 140 billion is,

t = 9.79 years

BC=3ft

AC=3ft

AB² =BC² + AC²=9+9=18ft²

In the right triangle ABD, AB²=18ft

BD=7ft

AB²+AD²=BD²

18+AD²=7²

AD²= 49-18

What is the value of the expression shown below 14 1/3 - 6 5/8

Answers

Answer:

the value of the expression 14 1/3 - 6 5/8 is 185/24.

Step-by-step explanation:

To solve this problem, you can convert both mixed numbers to improper fractions, then subtract the fractions and simplify the result. Here are the steps:

1. Convert 14 1/3 to an improper fraction:

14 1/3 = (14 x 3 + 1) / 3 = 43 / 3

2. Convert 6 5/8 to an improper fraction:

6 5/8 = (6 x 8 + 5) / 8 = 53 / 8

3. Subtract the fractions:

43 / 3 - 53 / 8 = (43 x 8 - 53 x 3) / (3 x 8) = (344 - 159) / 24 = 185 / 24

So the value of the expression 14 1/3 - 6 5/8 is 185/24.

Answers

The area of each of the pieces will be 9/16 m²

Given that =

Dimension of the rectangular paper:

length = 3/2 m

breadth = 3/4 m

Olivia cuts the paper into two pieces along its diagonal.

We need to find the area of the pieces,

Olivia will cut the rectangular paper along its diagonal into two pieces.

After cutting she will get two triangular pieces, which will be congruent to each other by SAS congruency.

∴ Area of each of the triangular pieces will be given by,

= ½ × Area of the rectangular paper

= ½ × [length × breadth]

= ½ × 3/2 × 3/4

= ½ × 9/8

= 9/16

Hence, the area of each of the pieces will be 9/16 m²

Part A To calculate slope, you need two points. Choose two points on the line. ​

Answers

The slope of this line is equal to 3/5.

How to calculate or determine the rate of change or slope of a line?

In Mathematics and Geometry, the gradient, rate of change, or slope of any straight line can be determined by using the following mathematical equation;

Slope (m) = (Change in y-axis, Δy)/(Change in x-axis, Δx)

Slope (m) = rise/run

Slope (m) = (y₂ - y₁)/(x₂ - x₁)

By substituting the given data points (0, 0) and (5, 3) into the formula for the slope of a line, we have the following;

Slope (m) = (y₂ - y₁)/(x₂ - x₁)

Slope (m) = (3 - 0)/(5 - 0)

Slope (m) = 3/5.

Find the area of the region inside the inner loop of the​ limaçon r=3−6cosθ.The area of the region is??

Answers

The area of the region inside the inner loop is 4.5π

How to calculate the area

Using the formula A = 1/2 ∫[a,b] r^2(θ) dθ. In the case of the limaçon's inner loop, a has been set as 0, b is equal to π, and r equals 3 - 6 cosθ. Together, these values give us the following equation expression for the area:

A = 1/2 ∫[0,π] (3 - 6 cosθ)^2 dθ

= 1/2 ∫[0,π] (9 - 36 cosθ + 36 cos^2θ) dθ

= 1/2 [9θ - 36 sinθ + 12 sin(2θ)]|[0,π]

= 1/2 [9π]

= 45π

Therefore, the area of the inner loop in this instance is calculated as 4.5π.
