£110 is divided between Sara, Gordon & Malachy so that Sara gets twice as much as Gordon, and Gordon gets three times as much as Malachy. How much does Sara get?

Answer:

21, 8

Step-by-step explanation:

The second endpoint is of the form (X, 8) since it's parallel to the x axis.

Given the congruence of the two segments, we can tell that its length is 16 units (since \(|4-20| = |-16|= 16\))

At this point the two possible endpoints for the segment are \((5-16; 8)\) or \((5+16, 8)\). The fact that the segment has to sit in the first quadrant rules out the first option (it's endpoint will be at (-11, 8) which will set most of it in the second quadrant) and we're left with (21, 8)

Answer:

1,500

Step-by-step explanation:

Remember that in a cost function, the cost per item is multiplied by x and the fixed cost is the part of the equation that is not multiplied by anything.

Cost = (Cost per item)(x) + Fixed cost

C(x) = 90x + 1,500

As you can see:

(Cost per item) would be 90

x would be, well x.

The fixed cost would be 1,500.

According to the information, we can infer that the correct expression is (10 * 7) + (2 * 7) (option D).

To find the correct expression we must look at the graph and interpret the information it has. In this case, some tiles are white and others are gray, so they would represent different elements. In this case, the white area is 10 * 7 tiles, so this would be the first part of the expression.

On the other hand, the second part of the expression would be 7 * 2, which represents the length, length and width of the gray area. According to the above, the correct expression would be (10 * 7) + (2 * 7), the first part in parentheses represents the white area and the second part in parentheses represents the gray area.

Step-by-step explanation:

i am working on the assumption that nobody does all three of them

i got 4 because including the people that do swimming and park, the total number of people that do swimming is 22.

the same logic goes for cycling: including the people that do swimming and visit the national park, the total is 23.

so that means that find how many people do swimming and cycling, we have to add the people doing only swimming, with the people doing both swimming and park and then subtract that answer from 22 which gives you 4

The pairs of operations involving multiplication and division are given as follows:

1. 9/3 = 3, then 3 x 3 = 9.

2. 9 x 2 = 18, then 18/2 = 9.

3. 40/8 = 5, then 5 x 8 = 40.

4. 63 = 7 x 9, then 63/9 = 7.

5. 80/10 = 8, then 10 x 8 = 80.

Using the radius of the Ferris wheel and the angle between the two positions, the time spent on the ride when they're 28 meters above the ground is 12 minutes

The radius of the Ferris wheel is 30 / 2 = 15 meters.

The highest point on the Ferris wheel is 15 + 4 = 19 meters above the ground.

The time spent higher than 28 meters is the time spent between the 12 o'clock and 8 o'clock positions.

The angle between these two positions is 180 degrees.

The time spent at each position is 10 minutes / 360 degrees * 180 degrees = 6 minutes.

Therefore, the total time spent higher than 28 meters is 6 minutes * 2 = 12 minutes.

Aircraft A has 312 seats.

Let's assume that Aircraft B has x seats.

According to the given information, Aircraft A has 105 more seats than Aircraft B. So, the number of seats in Aircraft A can be expressed as x + 105.

The total number of seats in both aircraft is 519, which can be represented by the equation:

x + (x + 105) = 519

Simplifying this equation, we have:

2x + 105 = 519

Subtracting 105 from both sides, we get:

2x = 414

Dividing both sides by 2, we find:

x = 207

Therefore, Aircraft B has 207 seats.

To find the number of seats in Aircraft A, we substitute the value of x back into the expression x + 105:

Aircraft A = 207 + 105 = 312

Hence, Aircraft A has 312 seats.

The total distance covered by the horse is 0.32km.

The perimeter of a rectangle is given by the formula:

Perimeter = 2 x (length + width)

We have

length = 100m and the width is 60m.

Substituting these values into the formula, we get:

Perimeter = 2 x (100 + 60) = 2 x 160

= 320m

The total distance covered by the horse is equal to the perimeter of the rectangle, which is 320m.

To convert the distance from meters to kilometers, we divide by 1000:

320m / 1000 = 0.32km

Answer:

(a) \(\hat y=69.04-0.083\cdot x\)

(b) D. For every unit increase in commute​ time, the index score falls by 0.083​, on average.

Step-by-step explanation:

(a)

Form the least-squares regression line using Excel as follows:

Go to Data → Data Analysis → Regression

A dialog box will open.

Select the X and Y variable.

Press Ok.

The regression output is attached below.

The least-squares regression line is:

\(\hat y=69.04-0.083\cdot x\)

(b)

The slope of a regression line is the average rate of change in the dependent variable (y) with 1 unit change in the independent variable (x).

Here the slope value is -0.083. This value implies that with 1 minute change in the commute times the Well-Being Index​ Score falls by 0.083 units.

The intercept of a regression line is the average value of the dependent variable (y) when the independent variable (x) value is 0.

Here, the intercept value is 69.04. This value implies that for a person with commute time 0, their Well-Being Index​ Score is 69.04.

The correct option is:

D. For every unit increase in commute​ time, the index score falls by 0.083​, on average.

Answer:

The proportion of arm spans that are longer than 170 cm is higher in Class B than in Class A.

Step-by-step explanation:

i used chatopenai.com you should use it for these

To find the proportion of arm spans that are longer than 170 cm for each class, you can count the number of arm spans in each class that are longer than 170 cm and divide it by the total number of arm spans in each class.

For Class A, there are 4 arm spans that are longer than 170 cm out of a total of 24 arm spans. Therefore, the proportion of arm spans that are longer than 170 cm for Class A is 4/24 = 1/6 = 0.17.

For Class B, there are 8 arm spans that are longer than 170 cm out of a total of 20 arm spans. Therefore, the proportion of arm spans that are longer than 170 cm for Class B is 8/20 = 2/5 = 0.40.

Since the proportion of arm spans that are longer than 170 cm is higher in Class B than in Class A, the correct statement is: above

The slope intercept form of the given equation is,

y = 5x - 1/4

Given an equation of a line as,

5x - y = 1/4

We have to write the equation of the line in slope intercept form.

Equation of the line in slope intercept form is,

y = mx + c

Here m is the slope and c is the y intercept.

Rearranging the given equation,

5x = y + 1/4

5x - 1/4 = y

or,

y = 5x - 1/4

Hence the slope intercept form is y = 5x - 1/4.
