Basically, there are two different types of geometric shapes such as: Two – Dimensional Shapes. Total area under graph = 15 + 12.56 + 3 + 20 = 50.56 sq. units

The area is the region bounded by the shape of an object. The space covered by the figure or any two-dimensional geometric shape, in a plane, is the area of the shape.

The area of shape is the space enclosed within the perimeter or the boundary of a given shape. We can calculate the area of shape for different geometrical shapes using specific mathematical formulae.

The area is the region bounded by the shape of an object. The space covered by the figure or any two-dimensional geometric shape, in a plane, is the area of the shape.

Area is measured in square units such as square inches, square feet or square meters. To find the area of a rectangle, multiply the length by the width. The formula is: A = L * W where A is the area, L is the length, W is the width, and * means multiply.

The area under the graph will be -

area of rectangle = length × breadth

= 5 × 3 = 15 sq. unit

area of circle = πr²

= 3.14 × 2 × 2

= 12.56 sq units

area of triangle = 1/2 × base × height

= 1/2 × 3 ×2

= 3 sq. units

area of trapezium = a + b / 2 . h

= 5 + 3 / 2 . 5

= 20 sq. units

area of triangle = 1/2 × 2 × 5 = 5 sq. units

Total area under graph = 15 + 12.56 + 3 + 20 = 50.56 sq. units

Answer: 93 [tex]\frac{1}{3}[/tex] yards³

Step-by-step explanation:

      We will find the volume in feet with this formula:

                               V = LWH

V = LWH

V = (140)(4)(0.5)

V = 280 feet³

      There are 3 feet in a yard, and the question asks for yards, so we will divide:

280 feet³ / 3 = 93 [tex]\frac{1}{3}[/tex] yards³

The probability that the proportion of a sample is higher than 0.30 can be estimated using the Central Limit Theorem (CLT) which states that the distribution of the sample means approaches a normal distribution as the sample size increases. With a large sample size (n >= 30), we can use the normal distribution to approximate the distribution of the sample means.

Assuming the sample size is large, the standard error (SE) of the sample mean is given by

SE = sqrt(p * (1 - p) / n), where p is the population proportion (0.27) and n is the sample size.

With this information, we can find the Z-score corresponding to 0.30 using the formula: Z = (0.30 - 0.27) / SE

Since we don't know the sample size, we'll assume a conservative sample size of 30.

With a sample size of 30, the SE is approximately 0.039, and the Z-score is approximately 0.77.

Using a standard normal table, we can find the probability of a Z-score being greater than 0.77 is approximately 0.22.

Therefore, the approximate probability that the proportion who exercise at least five days per week is higher than 0.30 is 0.22.

2 is the initial amount, growth rate is (3ˣ - 1) × 100% , domain of the function is all real numbers and  range of the function is all positive real numbers

A relation is a function if it has only One y-value for each x-value.

The given function is:

f(x) = 2(3)ˣ

To find the initial amount, we need to find f(0):

f(0) = 2(3)⁰ = 2(1) = 2

So the initial amount is 2.

To find the growth rate, we can use the formula:

growth rate = (f(x) - f(0)) / f(0) × 100%

= (2(3)ˣ - 2) / 2 × 100%

= (3ˣ - 1) × 100%

So the growth rate is (3ˣ - 1)×100%.

The domain of the function is all real numbers because the function is defined for all values of x.

The range of the function is all positive real numbers because the function is always positive for any value of x.

Specifically, the range of the function is (0, infinity).

Hence, 2 is the initial amount, growth rate is (3ˣ - 1) × 100% , domain of the function is all real numbers and  range of the function is all positive real numbers

x + 5/3 = 45/3

x = 40/3

P(X + Y < 4) = 0.53 rounded to the first decimal place.

To find the probability P(X + Y < 4),

we need to find the values of x1 and x2 that satisfy the condition

X + Y < 4, and then sum up the corresponding probabilities in the table.

We can start by plotting the points (x1, x2) on a graph and finding the region where X + Y < 4.

This region can be determined by shading in the portion of the graph that is below the line X + Y = 4.

Next, we need to find the values of x1 and x2 in the table that fall within this region and sum up their probabilities.

This gives us P(X + Y < 4) = 0.20 + 0.14 + 0.11 + 0.08 = 0.53.

Step-by-step explanation:

Answer:

101.  ΔABC congruent to ΔDEF

102. ΔJKL not congruent to ΔMNO

Step-by-step explanation:

Q 101

Triangle ABC has 3 sides equal  to each of the three sides of DEF

The corresponding two angles of ABC and DEF are also equal

So the third angle of ABC ∠B must be equal to the third angle of DEF so we have three sides equal, three angles equal, hence congruent

ΔABC congruent to ΔDEF

Q 102

We have JL = MP = 1.9

m∠J = m∠M = 24°

The other two angles are not correspondingly equal

This only makes one side equal and one angle equal. Not sufficient to make it congruent

Hence ΔJKL not congruent to ΔMNO

1)

The axis of symmetry is x = -6.

2)

Vertex is (-6, 26).

3)

f(x) has a maximum value.

4)

f(x) is concave down.

An equation is a mathematical statement that is made up of two expressions connected by an equal sign.

Example:

2x + 3 = 7 is an equation.

We have,

f(x) = -x² - 12x - 10

This is in the form of ax² + bx + c.

a = -1, b = -12, c = -10

The axis of symmetry is x = -b/2a

x = 12/(-2)

x = -6

Now,

f(x) = -x² - 12x - 10

f(x) = -(x² + 12x + 10)

f(x) = - { (x² + 12x + 36) - 36 + 10}

f(x) = -(x + 6)² + 26

This is in the form of f(x) = a (x - h)² + k

a = -1, h = -6, k = 26

Vertex = (h, k) = (-6, 26)

Now,

f(x) = -x² - 12x - 10

f'(x) = -2x - 12

f''(x) = -2

It is a negative value.

This means f(x) has a maximum value.

Now,

From the graph, we see that f(x) is concave down.

The required value of y for the given segment AB is given as y = 16, -8.

A line is a straight curve connecting two points or more showing the shortest distance between the initial and final points.

here,
A(0, 4), B(5, y), and AB = 13.

Applying the distance formula,
D = √[[x₂ - x₁]² + [y₂- y₁]²]

Substitue the value in the above expression,
13 = √[[5 - 0]² + [y - 4]²]
169 = 25 + [y - 4]²
[y - 4]² = 144
y - 4 = ± 12

y = 16, -8

In Geometry, dilation can be defined as a type of transformation which typically changes the size of a geometric object, but not its shape.

Additionally, a geometric figure that is translated downward simply means subtracting a digit from the value on the y-coordinate of the pre-image or parent function.

By critically observing the graph of the function shown above, we can logically deduce that it is a cube root function that has been vertically shifted by a scale factor of 2 units and then translated downward by 4 units. Therefore, this can be modeled by this equation as follows;

Katie spent approximately $285.544 on fuel during her vacation in Australia.

The Average Cost is the per unit cost of the product received by dividing the total cost (TC) by the total output (Q). By per unit cost of production, we mean that all the fixed and variable costs are considered for calculating the average cost. Thus, it is also called Per Unit Total Cost.

Symbolically, the average cost is expressed as:

AC = TC/Q

To estimate how much Katie spent on fuel, you need to multiply the number of gallons of gas she used (56 gallons) by the average cost of gas per gallon ($5.099):

56 gallons × $5.099/gallon = $285.544

Radius of Circle B = 6 cm + 3 cm = 9 cm

Radius of Circle C = 9 cm + 3 cm = 12 cm

Radius of Circle D = 12 cm - 2 cm = 10 cm

What is a circle's straightforward definition?

Simply put, a circle is a rounded shape without any edges or line segments. It has the geometric shape of a closed curve. The distance between the circle's points and its center is fixed.

The area of a circle is given by the formula: A = πr^2, where A is the area and r is the radius.

The area of Circle A is A = π(6 cm)^2 = 36π cm^2

The area of Circle B is A = π(9 cm)^2 = 81π cm^2

The area of Circle C is A = π(12 cm)^2 = 144π cm^2

The area of Circle D is A = π(10 cm)^2 = 100π cm^2

To find how many times greater than the area of Circle A is the area of Circle D, we can divide the area of Circle D by the area of Circle A:

100π cm^2 / 36π cm^2 = 2.78

The area of Circle D is 2.78 times greater than the area of Circle A.

Note: since π is a constant, we can ignore it for the purposes of comparing the areas of the circles. It will always be the same value and it will cancel out when dividing.
