Jose's height is 1 standard deviation above the mean height for 7-year-olds and Jamal's height is 0.67 standard deviations above the mean height for 12-year-olds.

Standard deviation is a mathematical term used to measure how far away a data point is from the mean of a set of data.

To determine the number of standard deviations, we use the following formula:

(Jose's height - mean height for 7-year-olds) / standard deviation

(130 - 120) / 10 = 1

So, Jose's height is 1 standard deviation above the mean height for 7-year-olds.

Now, let's look at Jamal. Let's assume that the mean height for 12-year-olds is 150 cm and the standard deviation is 15 cm. Jamal's height is 160 cm.

Using the same formula,

(Jamal's height - mean height for 12-year-olds) / standard deviation

(160 - 150) / 15 = 0.67

So, Jamal's height is 0.67 standard deviations above the mean height for 12-year-olds.

The standard deviation is a useful tool in understanding the spread of data and making inferences about the population mean based on sample means.

The standard deviation is a measure of how spread out the data is from the mean.

In this case, the mean recycled material collected per household in other local authorities is 40kg with a standard deviation of 15kg.

In part a, the probability of a randomly selected household recycling less than 30kg in a given week is calculated. In part b, the probability of the sample mean recycled material collected in a given week being less than 30kg for a sample of 100 households is calculated.

In part c, it is explained that finding a sample mean of 30kg for 100 households on a single street does not necessarily mean that the recycling scheme of local authority A is not working.

The required solutions of the situation of the function are  x = 3/4  or x = -1/4.

A unique connection where each input only produces one output. A common notation for it is "f(x)," where x denotes the input value. as in f(x) = x/2 ("f of x equals x divided by 2") Since there is only one output ("x/2") for each input ("x"), it is a function: • f(2) = 1.

We have,

f(x)=2x-1

g(x)=3/8x

To find the value of x for f(x) = g(x).

f(x) = g(x)

2x-1 = 3/8x

16x² - 8x = 3

16x² - 8x - 3 = 0

16x² - 12x + 4x - 3 = 0

4x(4x - 3) + (4x - 3) = 0

(4x - 3)(4x + 1) = 0

x = 3/4  or x = -1/4

The radius of the oil slick as a function of time t is R(t) = √((10/8) × 10000t/π), and after approximately 31.83 hours, the oil slick will have a radius of 1 kilometre.

(a) Let's assume that the oil spread rate is constant. Then, the volume of oil that has leaked into the ocean after t hours is 10000t litres. If this oil forms a circular slick of radius R, then its surface area is given by A = πR². If 8 litres of oil spread out over 10 square meters of the ocean surface, then 1 litre of oil spreads out over 10/8 square meters. Therefore, the surface area of the circular slick is given by

A = (10/8) × 10000t

Equating this to πR², we have:

πR² = (10/8) × 10000t

R² = (10/8) × 10000t / π

R = √((10/8) × 10000t / π)

So, the radius of the oil slick as a function of time t is:

R(t) = √((10/8) × 10000t / π)

(b) To find the time at which the oil slick has a radius of 1 kilometre, we set R(t) = 1 km and solve for t:

1 km = √((10/8) × 10000t / π)

1² km² = (10/8) × 10000t / π

π / (10/8) = 10000t / (1 km)²

π / (10/8) = 10000t / (1000 m)²

π / (10/8) = 10000t / (10⁶ m²)

Solving for t, we find:

t = π / (10/8) × (10⁶ m²) / 10000

t = π / (10/8) × 1000

t = (π × 1000) / (80)

So, after approximately 31.83 hours, the oil slick will have a radius of 1 kilometre.

According to the problem the mass of the prism is 207.875 g.

The measure of an object's matter content is its mass. It is typically measured in kilograms, grams, pounds, or ounces. Mass is related to weight, which is the measure of the force of gravity on an object, but the two terms are not interchangeable.

The mass of the prism can be calculated using the formula mass = density x volume. To calculate the volume of the prism, we can first calculate the area of the faces using the formula area = length x width. The area of the faces of the prism is 7.8 cm x 2.5 cm = 19.5 cm2. The volume of the prism is the area of the faces multiplied by the height, which is 2.5 cm. The volume of the prism is then 19.5 cm2 x 2.5 cm = 48.75 cm3. The mass of the prism is then density x volume, which is 4.3 g/cm3 x 48.75 cm3 = 207.875 g. Therefore, the mass of the prism is 207.875 g.

What is square root ?

A square root of a number x is a number y such that y² = x; in other words, a number y whose square is x.

x(r^2 x^(r-2)) - rx^(r-1) = 0

Expanding the powers of x and collecting terms, we have:

r^2 x^r - rx^r + x^r = 0

Dividing through by x^r, we have:

r^2 - r + 1 = 0

This is a quadratic equation that can be solved using the quadratic formula:

r = (-b ± √(b^2 - 4ac)) / 2a

where a = 1, b = -1, and c = 1.

Plugging in the values, we get:

r = (-(-1) ± √((-1)^2 - 4 * 1 * 1)) / 2 * 1

r = (1 ± √(1^2 - 4 * 1 * 1)) / 2 * 1

In one minute 0.6 sq meters of land will be cut with machete.

The unitary approach is a strategy for problem-solving that involves first determining the value of a single unit, then multiplying that value to determine the required value.

Direct Variation

When there is a direct variation, an increase or decrease in one quantity will result in an equivalent rise or fall in the other. For instance, a rise in the quantity of commodities will result in higher costs.

Additionally, a guy working alone will accomplish less than a man working with a group of men. Therefore, if we add more men, there will be more labor.

Indirect Variation

It is the direct variation's opposite. If we enhance one quantity, another item's value decreases. For instance, if we speed up, it will take us less time to travel a distance. Therefore, the distance traveled will be shorter as the speed increases.

As per the given triangle RT = AS, RS = AT, the statement < TSA = < STR is proved.

Given two triangles, if the length of one side is proportional to the length of a corresponding side in another triangle, then the two triangles are similar.

This relationship is expressed as "RT = AS," where R and S are corresponding vertices in the two triangles and T is the point where the two sides intersect.

To prove that < TSA = < STR, we need to show that corresponding angles in the two triangles are equal.

This is because corresponding angles in similar triangles are equal, and this is one of the ways to prove that two triangles are similar.

To prove that RT = AS and RS = AT, we can use the function of proportionality. This function states that if two sides are proportional, then the ratio of corresponding lengths will be equal.

Therefore, if RT = AS and RS = AT, then we can conclude that < TSA = < STR and the two triangles are similar.

The directional cosines of a vector are ratios of the components of the vector in the x, y, and z directions. Each directional cosine is a unit vector, meaning it has a magnitude of 1. Therefore, if the directional cosines of a vector are 5 and 6, as in the question, the magnitude of the vector would be the square root of (5^2 + 6^2), which is 7.81. Similarly, if the directional cosines are 2 and 3, the magnitude of the vector will be the square root of (2^2 + 3^2), which is 3.61.

To evaluate the integral, we can use partial integration.

Let u = 17z³

dv = e^z dz

Then du = 51z² dz

v = e^z

Using partial integration, we have:

∫ 17z³ e^z dz = 17z³ e^z - ∫ 51z² e^z dz

= 17z³ e^z - 51 * ∫ z² e^z dz

= 17z³ e^z - 51 * (z² e^z - 2 * ∫ z e^z dz)

= 17z³ e^z - 51z² e^z + 102 * ∫ e^z dz

= (17z³ - 51z² + 102) * e^z + c

So the definite integral from 0 to 2 is equal to

∫_0² 17z³ e^z dz = (17 * 2³ - 51 * 2² + 102) * e^2 - (17 * 0³ - 51 * 0² + 102) * e^0
