Answer:

  B.  -75

Step-by-step explanation:

Consider segments AC and A'C'. Point A' is clockwise from point A by an amount less than 90°. Positive angles are measured counterclockwise, so this suggests the angle of rotation is about -75°.

__

In the attached, we have used the invariant point on segments AC and A'C' as the vertex of the angle we want to measure. The angle between the lines appears to be about 75°, matching the answer choices.

Using the Central Limit Theorem, it is found that:

a) The shape is approximately normal.

b) It targets the population mean.

The Central Limit Theorem establishes that, for a normally distributed random variable X, with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]s = \frac{\sigma}{\sqrt{n}}[/tex].

For a skewed variable, the sampling distribution is also approximately normal, as long as n is at least 30.

Item a:

The variable is skewed, however, the sample size is greater than 30, hence the approximate shape of the distribution is normal.

Item b:

According to the mean of the sampling distributions, given by the Central Limit Theorem, it targets the population mean.

Answer:

6(b + 20) ≥ 26

Step-by-step explanation:

6(b + 20) ≥ 26

Answer:

6(b + 20) ≥ 26

b ≥ -15 2/3

Step-by-step explanation:

6(b + 20) ≥ 26

6b + 120 ≥ 26

6b ≥ -94

b ≥ -15 2/3

Separate the variables:

[tex]y' = \dfrac{dy}{dx} = (y+1)(y-2) \implies \dfrac1{(y+1)(y-2)} \, dy = dx[/tex]

Separate the left side into partial fractions. We want coefficients a and b such that

[tex]\dfrac1{(y+1)(y-2)} = \dfrac a{y+1} + \dfrac b{y-2}[/tex]

[tex]\implies \dfrac1{(y+1)(y-2)} = \dfrac{a(y-2)+b(y+1)}{(y+1)(y-2)}[/tex]

[tex]\implies 1 = a(y-2)+b(y+1)[/tex]

[tex]\implies 1 = (a+b)y - 2a+b[/tex]

[tex]\implies \begin{cases}a+b=0\\-2a+b=1\end{cases} \implies a = -\dfrac13 \text{ and } b = \dfrac13[/tex]

So we have

[tex]\dfrac13 \left(\dfrac1{y-2} - \dfrac1{y+1}\right) \, dy = dx[/tex]

Integrating both sides yields

[tex]\displaystyle \int \dfrac13 \left(\dfrac1{y-2} - \dfrac1{y+1}\right) \, dy = \int dx[/tex]

[tex]\dfrac13 \left(\ln|y-2| - \ln|y+1|\right) = x + C[/tex]

[tex]\dfrac13 \ln\left|\dfrac{y-2}{y+1}\right| = x + C[/tex]

[tex]\ln\left|\dfrac{y-2}{y+1}\right| = 3x + C[/tex]

[tex]\dfrac{y-2}{y+1} = e^{3x + C}[/tex]

[tex]\dfrac{y-2}{y+1} = Ce^{3x}[/tex]

With the initial condition y(0) = 1, we find

[tex]\dfrac{1-2}{1+1} = Ce^{0} \implies C = -\dfrac12[/tex]

so that the particular solution is

[tex]\boxed{\dfrac{y-2}{y+1} = -\dfrac12 e^{3x}}[/tex]

It's not too hard to solve explicitly for y; notice that

[tex]\dfrac{y-2}{y+1} = \dfrac{(y+1)-3}{y+1} = 1-\dfrac3{y+1}[/tex]

Then

[tex]1 - \dfrac3{y+1} = -\dfrac12 e^{3x}[/tex]

[tex]\dfrac3{y+1} = 1 + \dfrac12 e^{3x}[/tex]

[tex]\dfrac{y+1}3 = \dfrac1{1+\frac12 e^{3x}} = \dfrac2{2+e^{3x}}[/tex]

[tex]y+1 = \dfrac6{2+e^{3x}}[/tex]

[tex]y = \dfrac6{2+e^{3x}} - 1[/tex]

[tex]\boxed{y = \dfrac{4-e^{3x}}{2+e^{3x}}}[/tex]

Step-by-step explanation:

a² = a × a

a > 1

a² = (1+d) × (1+d) = 1² + 2d + d²

with d > 0

since d > 0, then so is 2d and also d².

so, a² is the sum of 1² = 1 and something greater than 0.

so, a² > 1

Answer:

Step-by-step explanation:

X would be adults Y would be children

3x+3y=35

2x+4y=25

One of the variables have to be equal to each other. So multiply all the terms in the bottom equation by 1.5

You get 3x+6y=37.5

Subtract one equation from another

3x+3y=35

3x+6y=37.5

You get 3y=2.5

Divide both sides by 3
y = 5/6

Now do the same but for X

Multiply the equation by 4/3

4x+4y=46 2/3

Minus the other equation

2x=21 2/3

Divide by 2

x = 10 5/6

An expression for x in terms of a and b is y = b - 2x and an expression for y in terms of a and b is y = 2a - b.

A numerical expression is a mathematical statement written in the form of numbers and unknown variables. We can form numerical expressions from statements.

Given, A system of equations x + y = a and 2x + y = b.

Now,

x + y = a.

x = a - y and y = a - x.

2x + y = b.

2x = b - y.

x = (b - y)/2.

y = b - 2x.

An expression for x in terms of a and b is,

x + y = a

x + b - 2x = a.

- x = a - b.

x = b - a.

An expression for y in terms of a and b is,

2(a - y) + y = b.

2a - 2y + y = b.

2a - y = b.

- y = b - 2a.

y = 2a - b.
