The probability that the average hourly rate of the 100 registered web developers sampled exceeds $35.5 is approximately 0.106, rounded off to the third decimal place.

The mean of the distribution of the hourly rate of registered web developers is $\mu = 35$ and the standard deviation is $\sigma = 4$. We are interested in finding the probability that the average hourly rate of the 100 registered web developers sampled exceeds $35.5$.

We can use the central limit theorem to approximate the sampling distribution of the sample mean. According to the central limit theorem, the sampling distribution of the sample mean will be approximately normal with mean $\mu_{\bar{x}} = \mu = 35$ and standard deviation $\sigma_{\bar{x}} = \frac{\sigma}{\sqrt{n}} = \frac{4}{{100}} = 0.4$.

Let $X$ be the sample mean hourly rate of the 100 registered web developers. Then we need to find $P(X > 35.5)$.

Standardizing $X$,we get:

Using a standard normal table or calculator, we can find the probability $P(Z > 1.25) \approximately 0.1056$. Therefore, the probability that the average hourly rate of the 100 registered web developers sampled exceeds $35.5$ is approximately 0.106, rounded off to the third decimal place

-1 and -11 are two integers that may multiply to produce 11 and also add to make -12.

In its most basic form, an equation is a mathematical statement that indicates that two mathematical expressions are equal. 3x + 5 = 14, for example, is an equation in which 3x + 5 and 14 are two expressions separated by a 'equal' sign. A mathematical statement made up of two expressions joined by an equal sign is known as an equation. 3x - 5 = 16 is an example of an equation. We get the value of the variable x as x = 7 after solving this equation.

Here,

Let x and y be the number.

x+y=-12

xy=11

y=11/x

x+11/x=-12

x²+12x+11=0

x²+11x+x+11=0

x(x+11)+1(x+11)=0

x=-11,-1

The numbers that can multiply to make 11, and also add together to make -12 are -1 and -11.

A number system is defined as a system of writing to express numbers. It is the mathematical notation for representing numbers of a given set by using digits or other symbols in a consistent manner.

Alex wants to multiply the number with 12.

She multiples by 6 first.

So, we need to focus on that what can be multiply by 6 to get 12 or what will be the quotient dividing 12 by 6.

Josue needs to invest $688.23 for the value of the account to reach $1,170 in 13 years

Borrowers are required to pay interest on interest in addition to principal since compound interest accrues and is added to the accrued interest from prior periods.

We know the formula for compound interest is,

A = P(1 + r/100)ⁿ.

Where, A = amount, P = principle, r = rate, and n = time in years.

The formula for compound interest compounded quarterly is,

A = P(1 + (r/4)/100)⁴ⁿ.

Kozol notices the stress on the 3,300 kids at Fremont during lunch, when the entire meal is provided in a single 30-minute period. One teacher estimates that the lengthy distance to the cafeteria and the lengthy queues for food provide children a 10-minute window during which to eat. As a result, many students frequently skip meals entirely (176).

Given,

Lunch was served to the pupils in this school in a single sitting, unlike the staggered luncheon sessions I saw at Walton High. 3,300 children cannot be fed at once due to physical limitations, the teacher explained. "The session lasts barely 30 minutes, and there is a very large line for children to obtain their food. They must wait in line for fifteen minutes before they can even walk there from their classes. They most likely have 10 minutes to eat their food. Many of them don't even try.

Answer: In 6 years the sum of Manas' age and his sister's age will be 48 years.

Step-by-step explanation:

We know that value of a dozen is 12 and the score is 20.

Hence,

Uncle Mike's age = 12+20 = 32 years

Since Manas' sister is 8 years younger than Mike,

Her age = 32 - 8 = 24 years

We know that Manas is half her age. Therefore,

Manas' age  = 24 ÷ 2 = 12 years

After x years the sum of Manas' age and his sister's age will be 48 years.

Manas' future age = (12 + x) years

His sister's future age = (24 + x) years

The Sum of their ages is 48 years. Hence,

(24 + x) + (12 + x) = 48

36 + 2x = 48

2x =  48 - 36

2x = 12

x = 12 ÷ 2

x = 6

Therefore, in 6 Years sum of their ages is 48 years.

The polynomial function f(x)=x²(x+2) in terms of end behavior approaches positive infinity as x approaches positive and negative infinity, the x-intercepts are at x = 0 and x = -2, the y-intercept is at the origin, the zeros are x = 0 (with multiplicity 2) and x = -2, there can be a maximum of 2 turning points.

a) The end behavior of the graph of the function is y approaches positive infinity as x approaches positive infinity and y approaches positive infinity as x approaches negative infinity.

b) The x-intercepts of the graph occur when f(x) = 0, which are x = 0 and x = -2. The y-intercept occurs when x = 0, which is y = 0.

c) The zeros of the function are x = 0 (with multiplicity 2) and x = -2. The lesser zero of multiplicity 2 means the graph touches the x-axis at x = 0. The greater zero of multiplicity 1 means the graph crosses the x-axis at x = -2.

Step-by-step explanation:

21 people rented paddle boards and 7 people rented kayaks

Total number of members in field trip = 27 + 1

= 28

The cost for rent paddle boards = $16

The cost for rent kayaks = $19

Total amount they spent = $469

Number of people rented paddle boards as x and number or people that rented as y

Then the equations will be

x + y = 28

x = 28 -y

The second equation will be

16x + 19y = 469

Here we have to use the substitution method

16(28-y) + 19y = 469

448 - 16y + 19y = 469

3y = 469 - 448

3y = 21

y = 21/3

y = 7

Then the value of x = 28 - y

= 28 - 7

= 21

The points jada score is 159.25.

Given that james scored 182 points while playing a video game and he scored 7 times as many points as jada scored.

Let x be the points scored by james and y be the points scored by jada.

The total points scored by james and jada is 182 points.

x+y=182    .....(1)

James scored 7 times many points as jada scored.

y=7x         .....(2)

So, there are two equations and two unkowns.

Firstly, we will substitute equation (2) in equation (1), we get

x+7x=182

8x=182

Divide both sides by 8, we get

8x/8=182/8

x=22.75

Further, we will substitute the value of x in equation (2), we get

y=7×22.75

y=159.25

Hence, the jada score 159.25 when james scored 182 points while playing a video game and ahe scored 7 times as many points as jada scored.

4ax²−3b+12x²−a = 4ax²+12x²−a−3b

Step-by-step explanation:

The system of first-order equations that is equivalent to the given second-order differential equation is dy/dt = z, dz/dt = w, and dw/dt = (-3z - 2w - 6y)/t².

To write the given second-order differential equation as a system of first-order equations, we need to introduce new variables.

Let z = dy/dt. Then, we can rewrite the given equation as

d³y/dt³ = dz/dt

d²y/dt² = dz/dt = z

Substituting these expressions into the original equation, we get

(t²) (d³y/dt³) + 3(d²y/dt²) + 2(dy/dt) + 6y = t² (dz/dt) + 3z + 2(dy/dt) + 6y

Simplifying and grouping the terms, we obtain

d/dt [y, z, w] = [z, w, (-3z - 2w - 6y)/t²]

where w = dt/dt = 1.
