Answer:

7*-5+2(-5+5)=-35

9*-5+10=-35

7*2+2(2+5)=28

9*2+10=28

Step-by-step explanation:

when plugging the x values in, you get the same answer for both equation, make the equation equal.

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.

To Find :-

Solution :-

Here a equation is given to us and we need to find out the slope of the line . The given equation is ,

→ y = -1/2x + 1/4

We know that slope intercept form of the line is ,

→ y = mx + c

where m is the slope of the line .

On comparing ,

Step-by-step explanation:

Hi!

The formula for volume is length * width * height

We are given the area of the base of the figure and the height.

The volume for area is length * width

That means that the length * width part of the volume formula is already done, so we just have to multiply that by the height.

[tex]3 \frac{3}{8}[/tex] * [tex]2[/tex]

[tex]6 \frac{6}{8}[/tex] [tex]= 6\frac{3}{4}[/tex]

We know that:

If L and B are multiplied, they will find the area of the base.

This means that:

Substitute the area of base of rectangular prism in the volume formula.

Substitute the height in the volume formula.

You can further solve this in two methods. You can use any of them.

Answer: 30% of the blend is pineapple juice

Step-by-step explanation:

Since 7 pineapples yield 12 oz of juice, 1 pineapple yields 1 5/7 oz of juice.

Since 4 apples yield 16 oz of juice, 1 apple yields 4 oz of juice.

She’s making a pineapple-apple juice where the ratio of apples and pineapples used is 1:1. To find what percent of the blend is pineapple juice:

1 apple to 1 pineapple. The combined amount of juice they produce is 5 5/7 oz. The formula to find what percent of teh blend is pineapple juice is oz of pineapple juice divided by the combined amount of juice in the blend.

1 5/7 divided by 5 5/7 equals 3/10, or 30%.

The fraction of the blend that is pineapple and apple gives the

percentage that is pineapple.

Response:

Amount of juice extracted from 7 pineapples = 12 ounces

Amount of juice extracted from 4 apples = 16 ounces

Therefore;

The amount of juice from 1 apple = [tex]\frac{16}{4}[/tex] ounces

Which gives;

The amount of juice from 1 pineapple and 1 apple =  [tex]\frac{12}{7}[/tex] + 4 = [tex]\frac{40}{7}[/tex] = [tex]5\frac{5}{7}[/tex]

b² = a² + c² - 2ac × cos (m∠B)

b² = 105² + 9² - 2(9)(105)cos65°

b ≈ 101.5

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

foruth root is 2^.25 e^(120/4)i

2^.25 e^30 i

2^.25 ( cos 30 + i sin 30)

Step-by-step explanation:

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]

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
