Using the data in the scatter plot what is a reasonable slope of a model that fits this data

Answers

We can conclude that the reasonable slope of a model that fits the given data is: C. 1.

What is the Slope on a Scatter Plot?

Slope = change in y/change in x.

To find the slope of that fits the data, pick any two points on the scatter plot, say, (12, 1985) and (16, 1988)

Slope = (1988 - 1985)/(16 - 12) = 0.75 ≈ 1.

Therefore, we can conclude that the reasonable slope of a model that fits the given data is: C. 1.

An equilateral triangle with side length 7 cm is shown in the diagram, work out the area of the triangle.
Give your answer rounded to 1 DP.

Answers

If a triangle has sides of 7 cm and it is an equilateral you can draw a line right down the middle to form two congruent triangles.

These smaller triangles have a hypotenuse of 7cm and a base of 3.5 cm (7/2)

To work out the height, use Pythagoras’ theorem.

a^2 + b^2 = c^2 where c is the hypotenuse and a and b are the other two sides

7^2 - 3.5^2 = 36.75

Square root answer

= 6.06 cm

That’s the height of the triangle

Area of a triangle is base x height divided by 2

So 7 x 6.06 = 42.43…

/2

= 21.2 cm^2 to one d.p

Answers

Answer:

113.04 ft^2

Step-by-step explanation:

area of circle formula = [tex]\pi r^{2}[/tex]

in this case, we are taking π as 3.14, so it is 3.14 x [tex]r^{2}[/tex]

Radius = half of diameter

radius = 12 / 2 = 6

[tex]6^{2}[/tex] = 36 (because 6 x 6 = 36)

3.14 x 36 = 113.04

Therefore, our answer is 113.04 ft squared (because it is area)

Sebastian bought a 30-pack of mechanical pencils and plans to give the same number of pencils each to 6 friends. Which equation can he use to find p, the number of pencils each friend will receive? p 6 = 30 p minus 6 = 30 6 p = 30 StartFraction p Over 6 EndFraction = 30.

Answers

The equation, that Sebastian can use to find p, the number of pencils each friend will receive is given by: Option C: 6p = 30

How to form mathematical expression from the given description?

You can represent the unknown amounts by the use of variables. Follow whatever the description is and convert it one by one mathematically. For example if it is asked to increase some item by 4 , then you can add 4 in that item to increase it by 4. If something is for example, doubled, then you can multiply that thing by 2 and so on methods can be used to convert description to mathematical expressions.

For this case, we're given that:

Sebastian has 30 pencilsSebastian will distribute p pencils to each of his 6 friends.

Now, that means, if we collect all those p pencils, then they should be 30 in count.

Sum of pencils from 6 friends = p + p + p + p + p + p = 30

or

[tex]6 \times p = 30[/tex] (since p was added 6 times itself, so we write it as 6 times p)

we don't write the "×" sign, (Using sign of multiplication is often hidden if there are non numeric symbols and numbers being multiplied are written together) Thus, the equation is 6p = 30 (well both equations are same).

Thus, the equation, that Sebastian can use to find p, the number of pencils each friend will receive is given by: Option C: 6p = 30

Answers

Answer:

24

Step-by-step explanation:

You can use a simple equation for this:

c=chickens, r=roosters

c=10+2r, as "chickens is TEN MORE than TWICE the number of roosters,"

we can then do;

10+2r+r (the original number of roosters)=31

3r=21

r=7

Determine the point estimate of the population mean and margin of
error for the confidence interval with lower bound 19 and upper bound: 27.

Answers

Using confidence interval concepts, it is found that:

The point estimate of the population mean is of 23.The margin of error is of 4.

Given a confidence interval what are the point estimate of the population mean and the margin of error?A confidence interval has two bounds, a lower bound and an upper bound.A confidence interval is symmetric, which means that the point estimate used is the mid point between these two bounds, that is, the mean of the two bounds.The margin of error is the difference between the two bounds, divided by 2.

In this problem, the interval is (19,27), hence the point estimate is:

P = (19 + 27)/2 = 23.

The margin of error is:

M = (27 - 19)/2 = 4.
