If the best fit line is nearly horizontal, it suggests no significant relationship between height and head circumference.

In this scenario, the explanatory variable is the child's height, as it is being used to predict the head circumference.

The response variable is the head circumference itself, as it is the variable being predicted or explained by the height.

To draw a scatter diagram of the data, you would plot the child's height on the x-axis and the corresponding head circumference on the y-axis. Each data point would represent a child's measurement pair.

Once all the data points are plotted, you can then draw the best fit line, also known as the regression line, that represents the overall trend or relationship between height and head circumference.

By observing the scatter diagram and the best fit line, you can determine the relationship between a child's height and head circumference.

If the best fit line has a positive slope, it indicates a positive relationship, meaning that as height increases, head circumference tends to increase as well.

If the best fit line has a negative slope, it indicates a negative relationship, meaning that as height increases, head circumference tends to decrease.

By assessing the slope of the best fit line in the scatter diagram, you can determine whether the relationship between height and head circumference is positive, negative, or nonexistent.

Subtract 4 from both sides of the equation, then subtract f from both sides and divide both sides by -7/2 to solve for f.

In order to solve for f, the equation must be manipulated to isolate it on one side of the equation. To do this, the equation must be manipulated algebraically. First, subtract 4 from both sides of the equation. This will move the constant part to the other side of the equation, leaving only the f on the left side. Then, subtract f from both sides, which will move the f to the other side and leave only the constant on the left side. Finally, divide both sides of the equation by -7/2. This will move the coefficient of f to the other side and will leave only f on one side of the equation, thus isolating it. The resulting answer is f=1. This process of manipulating the equation algebraically is called solving the equation for f.

Step-by-step explanation:

Stephen makes the mistake in the expression as he uses the 4 in the root and the 3 in the power and the expression actually is: ∛(16)/e

We start with the expression:

exp( (4/3)*ln(2) - 1)

Here we can use that:

exp(ln(x)) = x.

and e^(a + b) = e^a*e^b.

the first step here is:

e^((4/3)*ln(2) - 1) = e^((4/3)*ln(2)*e^(-1)

So the first step of Stephen is correct, but the first step of Helen is not, you can not simplify the expression in that way.

now, we have that:

a*ln(x) = ln(x^a)

then we can write:

(4/3)*ln(2) = ln(2^(4/3))

and e^(ln(2^(4/3)) = 2^(4/3)

then we have:

e^((4/3)*ln(2)*e^(-1) = 2^(4/3)/e

now we can write this as:

∛(2^4)/e

For the given question,

The data for the storage battery are-

Part a: The probability that a given battery will last between 2.3 and 3.6 years.

Find z score for x = 2.3 years.

z(2.3) = (x - μ )/σ

Put the values,

z(2.3) = (2.3 - 3.0)/0.5

z(2.3) = -1.4

Use negative z score table;

P(z = -1.4) = 0.0808

Similarly, for x = 3.6

z = (3.6 - 3)/0.5

z = 1.2

Use positive z table;

z = 0.8849

P(2.3<x<3.6) = 0.8849 - 0.0808

P(2.3<x<3.6) = 0.8041

Thus, the probability that a given battery will last between 2.3 and 3.6 years is 80.41%.

Part b: The probability that a given battery will last longer than 24 months = 2 years.

x = 2 years

z (2) = ( 2 - 3.0 )/ 0.5

z = 2

P(x > 2) = 0.9772

Thus, the probability that a given battery will last longer than 24 months is 97.72%.

Step-by-step explanation:

Since angle y and angle x form vertical angles, the measure of angle x is equal to 50°.

In Geometry, the vertical angles theorem is also referred to as vertically opposite angles theorem and it states that two (2) opposite vertical angles that are formed whenever two (2) lines intersect each other are always congruent, which simply means being equal to each other.

Furthermore, the sum of the angles on a straight line is equal to 180. Therefore, we would sum up all of the angles as follows;

60° + 70° + y = 180°

130° + y = 180°

y = 180° - 130°

y = 50°

Since both angle x and angle y are vertical angles, we can logically deduce that they are congruent and as such the magnitude of angle x is equal to 50°.

Answer:

30⁰ , 60⁰ , 90⁰

Step-by-step explanation:

Let the angles x , 2x , 3x

By angle sum property:

x + 2x + 3x = 180⁰

6x = 180⁰

x = 30⁰

Angles are : 30⁰ , 60⁰ , 90⁰

Let one angle be x, the second 2x and the third 3x.

x + 2x + 3x = 180 degrees (angle sum property of a triangle)

6x = 180 degrees

x = 180/6

x = 30 degrees

So one angle is 30°, the second is 60°, and the third is 90°.

The net profit for the year ending December 31, 2021, is £1,000. Therefore, the correct answer is d) £1,000.

To determine the net profit for the year ending December 31, 2021, we need to calculate the total revenue and subtract the total expenses. Let's analyze the transactions provided:

The owners invested £550,000 of their own funds into the business bank account. This does not affect the net profit as it represents an owner's contribution of capital.

The business used £16,000 from the bank account to purchase short features and fashion. This expense reduces the net profit.

The business used £10,000 from the bank account to buy new inventory. This expense also reduces the net profit.

The business bought additional inventory worth £9,000 on credit. This is not an expense for the current year as it represents an increase in assets.

The shop sold £28,000 worth of inventory to customers for cash. This revenue increases the net profit.

The business sold goods costing £6,000 to another business on credit for £8,000. This revenue also increases the net profit.

The business paid £9,000 in rent from the bank account. This expense reduces the net profit.

Depreciation and estimated electricity expenses are not mentioned in the given transactions and cannot be calculated.

The owners withdrew £10,000 in cash for personal use. This is not an expense for the business and does not affect the net profit.

Based on the provided information, we can calculate the net profit as follows:

Total Revenue = £28,000 (from sales to customers) + £8,000 (from sales to another business) = £36,000

Total Expenses = £16,000 (short features and fashion) + £10,000 (new inventory) + £9,000 (rent) = £35,000

Net Profit = Total Revenue - Total Expenses = £36,000 - £35,000 = £1,000

Therefore, the net profit obtained is £1,000.

Answer:linear

Step-by-step explanation:

A boat takes 3.40 hours to travel 25.0 km down a river, then 4.60 hours to return, so the river is flowing at the speed of 0.95km/hrs.

Let x represent the boat's speed on still water.

Let y equal the current's speed.

The time is 3.40 hours, and the rate is x + y with the current.

The time is 4.60 hours, and the rate against the current is x - y.

rate x time = downstream

distance (x + y) * 3.40 = 25

Thus, upstream, 3.4x + 3.4y = 25. (x - y) * 4.60 = 25 so 4.6x - 4.6y = 25

Add 4.6 to both sides of the "downstream" equation and 3.4 to both sides of the "upstream" equation:

15.64x + 15.64y = 115

15.64x - 15.64y = 85

When the two equations are combined: 31.28x = 200, so x = 6.4

In other words, 15.64(6.4) + 15.64(y) = 115 and 100 + 15.64y = 115 are equivalent to 15.64x + 15.64y = 115.

120 is subtracted from both sides: 15.64y = 15, so y = 0.95

The speed of the boat in still water is 6.4 km per hour

The speed of the current is 0.95 km per hour.

Answer:

Step-by-step explanation:

To find the coordinates of the points where the line 10x - 8y = 40 intersects the x- and y-axes, we can set one of the variables to zero and solve for the other variable.

For the x-intercept (where the line intersects the x-axis), we set y = 0 and solve for x:

10x - 8(0) = 40

10x = 40

x = 40/10

x = 4

Therefore, the x-intercept is (4, 0).

For the y-intercept (where the line intersects the y-axis), we set x = 0 and solve for y:

10(0) - 8y = 40

-8y = 40

y = 40/-8

y = -5

Therefore, the y-intercept is (0, -5).

In summary, the coordinates of the points where the line 10x - 8y = 40 intersects the x- and y-axes are:

x-intercept: (4, 0)

y-intercept: (0, -5)

A current account surplus occurs when a country's total exports of goods, services, and transfers exceed its total imports. This means that the country is exporting more than it is importing, resulting in a positive balance of trade.

There are several reasons why a current account surplus may occur:

1. Strong Export Performance: When a country's industries are competitive and can produce goods and services that are in high demand globally, its exports will increase. This can be due to factors such as low production costs, high-quality products, or unique resources.

2. Weak Import Demand: If a country's domestic demand for imported goods and services is low, it can contribute to a current account surplus. This may be influenced by factors such as a slow economy, high savings rate, or government policies that discourage imports.

3. Currency Exchange Rates: A country with a relatively weak currency can have an advantage in international trade. A weaker currency makes its exports more affordable and competitive in foreign markets, boosting exports and potentially leading to a current account surplus.

4. Favorable Terms of Trade: When a country experiences an improvement in the terms of trade, it means that the prices of its exports increase relative to the prices of its imports. This can lead to higher export revenues and a current account surplus.

5. Foreign Investment Income: If a country receives significant income from investments abroad, such as profits, dividends, or interest, it can contribute to a current account surplus. This income adds to the country's earnings from exports and reduces its reliance on imports.

6. Capital Inflows: When foreign investors invest in a country's assets, such as stocks, bonds, or real estate, it leads to capital inflows. These inflows can contribute to a current account surplus as they increase the country's financial account balance.
