Write an inequality to describe all the points on the coordinate plane above y=-4?

There are 11 letters in the word mathematics. The probability of selecting the letter "e" first is 1/11, which is approximately 0.091 in decimal form when rounded to the nearest thousandth.

This is because there is only one "e" in the word mathematics, and we are selecting one letter out of the 11 total letters.

To find the probability that the first letter is "e" in the word "mathematics," follow these steps:

1. Count the total number of letters in the word: There are 11 letters in "mathematics."

2. Count the occurrences of the letter "e": There is 1 "e" in "mathematics."

3. Calculate the probability: Divide the occurrences of "e" by the total number of letters.

Probability = (Occurrences of "e") / (Total number of letters) = 1 / 11

In decimal form and rounded to the nearest thousandth, the probability that the first letter is "e" in the word "mathematics" when arranged randomly is approximately 0.091.

Answer:

3 : 7

Step-by-step explanation:

Ratios are Proportinalised Numbers that we can use to compare number of units relative to the other value.

Eg. 3 : 15 = 1 : 5

Given Information from the Question:

15 Child Tickets : 35 Adult Tickets

Now we reduce them to simplest form.

(15 ÷ 5) : (35 ÷ 5) = 3 : 7.

Therefore the ratio of Child Tickets to Adult Tickets is 3 : 7.

Answer:

We can use the Pythagorean theorem to find the length of the hypotenuse:

c^2 = a^2 + b^2

where c is the length of the hypotenuse, and a and b are the lengths of the other two sides.

Plugging in the given values, we get:

c^2 = 16^2 + 10^2

c^2 = 256 + 100

c^2 = 356

Taking the square root of both sides, we get:

c = sqrt(356)

c ≈ 18.9

Therefore, the length of the hypotenuse is approximately 18.9 cm.

The position value, r(t) is equals to the (t³/6)k + 2j and velocity value, v(t) is equals to ( t²/2 )k + 4i , for a(t) = tk, v(0) = 4i, r(0) = 2j.

Acceleration is defined as the rate of change of the velocity of an object with respect to time. Accelerations are vector quanty.

a = dv/dt

We have the following informations are available,

Initial velocity, v(0) = 4i

Initial position, r(0) = 2j

Acceleration at any time "t",

a(t) = tk

we have to determine the value of v(t) and r(t).

As we know, a(t) = dv(t)/dt = tk

integrating the above equation ,

v(t) = ∫tk dt = ( t²/2 )k + c

at t = 0 , v(0) = 0 + c = 4i ( since, v(0) = 4i

=> c = 4i

So, v(t) = ( t²/2 )k + 4i

Also, velocity is calculated by derivative of postion (r) with respect to time.

=> v(t) = dr(t) /dt

=> r(t) = ∫ v(t) dt

=> r(t) = ∫ ( t²/2 )k dt

integrating value of the right hand side,

r(t) = ( t³/2×3 )k +d

= (t³/6)k + d

At t = 0, r(0) = (0/6)k + d

=> r(0) = d = 2j

so, r(t) = (t³/6)k + 2j

Hence, the required position and velocity are

(t³/6)k + 2j and ( t²/2 )k + 4i.

Answer:

£18

Step-by-step explanation:

The VAT (Value Added Tax) is calculated as a percentage of the original price, so we need to add 20% of the original price to get the total price including VAT.

To find out how much Amir pays for the jumper including VAT, we first need to calculate the VAT:

VAT = 20% of £15

= (20/100) x £15

= £3

So, the VAT on the jumper is £3.

To find out the total price Amir pays for the jumper including VAT, we need to add the VAT to the original price:

Total price = Original price + VAT

= £15 + £3

= £18

Therefore, Amir pays £18 for the jumper including VAT.

Thus, the sum of palindromic primes less than 100 is 2+3+5+7+11+101=129.

Palindromic primes are two-digit prime numbers such that the number formed when the digits are reversed is also prime. The sum of all palindromic primes less than 100 is 2+3+5+7+11+101=129.

The first palindromic prime number is 11. We note that for palindromic numbers to be prime, the digits at the units and ten's place must be odd (1, 3, 5, 7, or 9).

Thus, a number would be palindromic if it is formed in the following ways:

a. The tens place would be a digit from the given set of digits

b. The units place would be the same as the digit at the tens place

The primes that fit these criteria are 11, 22, 33, 44, 55, 66, 77, 88, and 99.

However, only 11, 33, 55, and 77 are prime.

The correct answer is (C) more than, nominal.the correct answer is (C) more than, nominal. Your hourly wage of $12 in 2022, adjusted for inflation,

To compare the wages between 1972 and 2022, we need to adjust for inflation. Inflation refers to the general increase in prices over time, which reduces the purchasing power of a currency. To calculate the nominal wage in 2022, we need to account for the inflation that occurred since 1972.

Using the inflation data, we can calculate the equivalent wage in 2022 dollars. According to the Bureau of Labor Statistics' inflation calculator, $4 in 1972 is equivalent to approximately $25.73 in 2022. This means that if your grandfather's wage in 1972 were adjusted for inflation, it would be $25.73 in 2022.

Comparing this to your hourly wage of $12 in 2022, we can see that your wage is indeed more than three times your grandfather's wage in terms of income (adjusted for inflation). Mathematically, we can express this as:

$12 (your wage) > 3 * $25.73 (grandfather's adjusted wage)

Therefore, the correct answer is (C) more than, nominal. Your hourly wage of $12 in 2022, adjusted for inflation, is more than three times your grandfather's wage of $4 in 1972.

It will take 3703 square inches of paint to completely cover the table which is the surface area. Hence, option B is the best one.

It deals with the dimensions, regions, and densities of the various 2D and 3D shapes.

A cylinder may be used to represent the table's top, and rectangular prisms can be used to represent the table's legs

The cylinder's surface area will be

SA of cylinder equals 2\(\pi r^2\) + 2\(\pi\)rh

SA of the cylinder equals 2 \(\pi\)(\(18^2\) + 18 x 3).

SA of the cylinder equals 2375 square inches.

therefore the prism's surface area will be

Prism SA = 4 [WL + 2(WH + LH)].

Prism's SA =4 [2 x 6 + 2 (2 x 20 + 6 x 20)]

SA of prism = 4 [12 + 2 x 160]

SA of prism = 4 [12 + 320]

SA of prism = 1328 square inches

so the table's total surface area will be

SA of the prism plus SA of the cylinder equals total surface area.

Surface area total = 1328 + 2375

3703 square inches are all of the surface.

Hence, 3703 square inches of paint will be required to completely cover the table.

Proportional relationships are those in which the ratios of two variables are equal. Another way to think about them is that one variable in a proportional relationship is always a constant value multiplied by the other. This is known as the "constant of proportionality."

A proportional relationship exists when each pair of data values is related in the same way, by multiplying by a factor. A proportional relationship can be identified by looking at data, an equation, or a graph. A proportional relationship with a constant of proportionality k between two quantities y and x is represented by the equation y = kx.

They pass through the source. They are linear (straight lines) and pass through the origin as well. The x to y ratio is a proportionality constant. For example, consider the following number pairs with a ratio of 2.5: 5 and 2; 10 and 4; 100 and 40; 2.5 and 1. These number pairs are all proportional to one another.
