The estimation number of death from measles occured in developing countries in 2019 is 1.9 million deaths.

To estimate the number of deaths from measles in developing countries, we can use the following calculation:

Deaths = (Total number of cases in developing countries) × (Fatality rate in developing countries)

According to the World Health Organization, 75% of measles cases occurred in developing countries in 2019. Assuming a total of 10 million cases worldwide, 7.5 million cases would have occurred in developing countries.

The fatality rate in developing countries is approximately 25%, so:

Deaths = (7.5 million cases) × (0.25) = 1.875 million deaths.

Deaths = 1.875 million deaths ≈ 1.9 million deaths

So, 1.9 million deaths from measles are likely to have resulted in developing countries in 2019.

iv) The relative change of the Tuition from 2009 to 2014 is given as follows: 26.59%.

Tuition has increased more in this time period.

The absolute change between two amounts is given by the absolute value of the difference of these two amounts.

Hence for the CPI from 2009 to 2014 is given as follows:

236736 - 214537 = 22,199

For the Tuition, it is given as follows:

126.15 - 99.65 = $26.5.

The relative change is given by the absolute change divided by the initial value and multiplied by 100%, hence:

Due to the higher relative change, the Tuition increased more in this time period.

The vertex form of the equation of the parabola is the quadratic equation y - 3 = - 3 · (x + 4)².

Parabolae are represented by quadratic equations, there are two forms for such equations: (i) standard form, (ii) vertex form. The vertex form of the equation of the parabola is shown below (please notice that parabola is parallel to y-axis when axis of symmetry is a vertical line):

y - k = C · (x - h)²

Where:

If we know that h = - 4, k = 3 and (x, y) = (- 3, 0), then the equation of the parabola in vertex form is:

C = (y - k) / (x - h)²

Yes, because the determinant of the coefficient matrix is 8

Step-by-step explanation:

If the determinant of a coefficient matrix is zero, then the linear system of equations it represents has no solution.

Here the coefficient matrix is

The determinant of a matrix
[tex]\begin{pmatrix}a\:&\:b\:\\ c\:&\:d\:\end{pmatrix}[/tex]

Answer:

The change in gravitational potential energy from point A to point B can be calculated using the formula:

ΔU = mgh

Where:

m = mass of the pendulum = 1.5 kg

g = acceleration due to gravity = 9.8 m/s^2

h = change in height = yB - yA = 0.12 m - 0.04 m = 0.08 m

So, the change in gravitational potential energy from A to B is:

ΔU = (1.5 kg)(9.8 m/s^2)(0.08 m) = 1.176 J

So, the change in gravitational potential energy from A to B is 1.176 Joules.

Step-by-step explanation:

Perpendicular definition is that two gradients multiplying each others must equal to -1. This can be written in the form of [tex]\displaystyle{m_1m_2=-1}[/tex] where m stands for gradient or slope.

First, we know that the gradient of a line is 5/6, we'd have to find another gradient that is perpendicular to each other. Hence, substitute in the equation:

[tex]\displaystyle{\dfrac{5}{6}m_2=-1}[/tex]

Solve for [tex]m_2[/tex], multiply both sides by 6 first:

[tex]\displaystyle{\dfrac{5}{6}m_2 \times 6=-1 \times 6}\\\\\displaystyle{5m_2=-6}[/tex]

Divide both sides by 5:

[tex]\displaystyle{\dfrac{5m_2}{5}=\dfrac{-6}{5}}\\\\\displaystyle{m_2=-\dfrac{6}{5}}[/tex]

Therefore, the gradient that is perpendicular to 5/6 is -6/5

The gradient of a line perpendicular to a line with a gradient of ⅚​ is -5/6.

We have,

A line perpendicular to a line with a gradient of ⅚​ will have a gradient that is the negative reciprocal of ⅚​.

The negative reciprocal of ⅚​ can be found by taking the reciprocal of ⅚​ (which is 6/5) and then negating the result.

So the gradient of the perpendicular line is:

-1/(6/5) = -5/6

Therefore,

The gradient of a line perpendicular to a line with a gradient of ⅚​ is -5/6.

Step-by-step explanation:

Answer:

To determine the amount of the investment after 7 years, we can use the formula:

A = P(1 + r/n)^(nt)

Where:

A = the future value of the investment (the amount after 7 years)

P = the initial principal or investment amount ($2750)

r = the annual interest rate (3.5%)

n = the number of times the interest is compounded per year (quarterly)

t = the number of years the investment is held (7)

First, we convert the annual interest rate to a decimal: 3.5% = 0.035

Then we convert the interest rate to a quarterly rate by dividing by the number of times it is compounded per year: 0.035 / 4 = 0.00875

We can now substitute these values into the formula:

A = $2750(1 + 0.00875)^(4*7)

A = $2750(1.00875)^28

A = $2750(1.3471)

A = $3710.82

So, the amount of the investment after 7 years is $3710.82, rounded to the nearest hundredth.

Step-by-step explanation:

Since the man was 26 years old when his son was born, his age is 26 more than his son's age, or mathematically speaking, x + 26 if the age of his son is x.

26 + x - dad's age

x - son's age

3 x son's age = dad's age

3x = 26 + x

x = 13

His son is 13 years old.

1.) c.) They are reciprocals

2.) a.) They are equal

3. b.) They are complementary

The non-right angles in a right triangle are he two acute angles in the right triangle.

1) Complementary angles are angles that have a sum of 90°

Let A and B be two complementary angles, we get;

m∠A + m∠B = 90°

Let a and b represent the lengths of the opposite sides to the complementary angles ∠A and ∠B

Let side a represent the side opposite to the angle ∠A and let side b  represent the side opposite to the angle ∠B, we get

tan(A) = a/b tan B = b/a

Therefore, tan(B) is the reciprocal of tan(A)

The correct option is c,) They are reciprocals

2) Let r represent the length of the hypotenuse of the right triangle, we get;

sin(A) = a/r

cos(A) = b/r

sin(B) = b/r

cos(B) = a/r

The values, sin(A) = cos(B), and sin(B) = cos(A), therefore;

3) The sum of angles in the right triangle is 180°, therefore;

m∠A + m∠B + 90° = 180°

m∠A + m∠B = 180° - 90° = 90°

m∠A + m∠B = 90°

Answer:

Step-by-step explanation:

First, we need to convert the area of 15 feet by 10 feet to square feet. That is 15*10 = 150 sq ft.

We know that 22 people fit comfortably in a 150 sq ft area, so we can estimate the number of people that can fit in a given area by dividing the area by the number of square feet per person.

So if we have an area of 10 feet deep on one side of the street along a 1-mile section of a parade route, we can estimate the number of people that can fit in that area by using the following equation:

(Area of crowd) / (Square feet per person) = Number of people

We know that 1 mile = 5280 feet, so the area of the crowd is 10*5280 = 52,800 sq ft.

Now we can estimate the number of people that can fit in that area by dividing the area by the number of square feet per person:

52,800 sq ft / 150 sq ft/person = 352 people

So, we can estimate that around 352 people can fit comfortably in a crowd that is 10 feet deep on one side of the street along a 1-mile section of a parade route.

What is a function?

A relation between a collection of inputs and outputs is known as a function. A function is, to put it simply, a relationship between inputs in which each input is connected to precisely one output.

Here, we have

Given: Luke buys a certain brand of cereal that costs $11 per box. Luke changes to a super-saving brand of the same size.

The function of the first cereal is

y = 11x

Now, another cereal that Luke decides to buy is $9 per box, which is expressed

y = 9x

Now, the difference between the costs is $2, because 11-9=2.

So, the original brand costs $2 more than the super-saving brand.

Now, if Luke buys 5 cereal boxes per month, the cost in each case would be

y = 11(5) = 55

y = 9(5) = 45

Luke is saving per month 55 - 45 = $10

There are 10 different ways to choose three products out of five.

What are permutation and combination?

Permutation and combination are mathematical concepts used to study the arrangements and selections of items.

Permutation: An arrangement of items, where order matters.

Combination: A selection of items, where order does not matter.

In this case, the manager has to choose three products out of five possibilities, which is a combination problem. To find the number of different ways to choose three products out of five, we can use the formula: nCr = n! / (r! (n - r)!).

n = 5 (number of items)

r = 3 (number of items to be chosen)

nCr = 5! / (3! (5 - 3)!) = 5! / (3! 2!) = (5 x 4) / (2 x 1) = 10.

Hence, there are 10 different ways to choose three products out of five.
