Step-by-step explanation:

Answer:

(4,6)

Step-by-step explanation:

To calculate the midpoint of two points, just calculate the arithmetic mean (average) of the x and y values of the two points given. For example, it is easy to see visually that the midpoint of (2, 0) and (4, 0) is (3, 0), since (3,0) falls right in the middle of the two points. However, the way to calculate this would be to take the average of 2 and 4 (3), along with the average of 0 and 0 (0). This process gives us our new point (3, 0). In case this doesn't make sense, here is the formula for the midpoint of two points - (x1,y1) and (x2,y2):

[tex]M=(\frac{x1+x2}{2},\frac{y1+y2}{2} )[/tex]

For this problem, E is (2,4) and F is (6,8). So, the midpoint would be:

[tex](\frac{2+6}{2},\frac{4+8}{2})=(\frac{8}{2},\frac{12}{2})=(4,6)[/tex]

Therefore, the midpoint is (4,6)

Answer:

Because of one man’s actions, whales never eat human beings.

Step-by-step explanation:

You define complex numbers as the reals, i, as usually defined, and their linear combinations using real coefficients, then,

The reals are complex numbers, even if you haven’t fully defined their properties.

If you define complex numbers as the form (a,b) with and a, b are real numbers, then you can say that each real number a is isomorphic with that complex number,

if b=0 once you define their properties.

A complex number can be visually represented as a pair of numbers (a, b) forming a vector on a diagram called an Argand diagram, representing the complex plane.

Of course, (0,1) will be i. You’ll have to define the multiplication rule, etc.

In actual usage, we gloss over the distinction, and real numbers are complex numbers with no imaginary part.

Answer: Algebraic expression

Step-by-step explanation:

BC = EF

the side has to lie between the two angles

The slope m = -1 and the y-intercept = ( 0, 4 ).

The graph is a solid line, shaded area above the boundary line since y is greater than -x + 4.

Given that;

y ≥ -x + 4

First, we use the slope intercept form y = mx + b to determine the slope and y-intercept.

y ≥ -x + 4

y = mx + b

We can see that;

m = -1

b = 4

Hence, the slope m = -1 and the y-intercept = ( 0, 4 ).

The graph is a solid line, shaded area above the boundary line since y is greater than -x + 4.

Answer:

4 ounces

Step-by-step explanation:

I'm assuming when it says: [tex]33\frac{1}{3}%[/tex]% it means 33.3333333333 instead of 33/3.

Anyways under that assumption, we currently have 20 ounces in the grape juice, since 4 ounces is grape juice concentrate and 16 ounces is water. So currently let's just say that the total amount of grape juice concentrate is going to be: [tex](4+x)[/tex] where x is the amount of grape juice concentrate you need to add to make it 33.33%. The next thing to know is how to calculate how much percent a is of b. This can be calculated using the equation: [tex]\frac{a}{b}*100[/tex]. So in this case the a is going to be the grape juice concentrate, and the b is going to be the entire mixture (water and grape juice). Since the concentrate is having x added to it, that means the entire thing is also having x added to it. This means we have the equation: [tex]\frac{4+x}{20+x} * 100[/tex], since we already have 4 ounces of grape juice concentrate, and we already have 20 ounces in total (16 ounces of water + 4 ounces of grape juice). This is going to be equal to 33.33%, or in other words 33 1/3. So to make this a bit easier, I'm going to convert this mixed fraction into one fraction, this gives you the fraction: [tex]\frac{100}{3}[/tex]. So now that's all left to do is set these two expressions equal to each other and solve for x

Original equation

[tex]\frac{4+x}{20+x}*100=\frac{100}{3}[/tex]

Divide both sides by 100

[tex]\frac{4+x}{20+x}=\frac{100}{3}\div 100[/tex]

Keep fraction, change division to multiplication, flip 100

[tex]\frac{4+x}{20+x}=\frac{100}{3}* \frac{1}{100}[/tex]

The 100 in the numerator will cancel out the one in the denominator

[tex]\frac{4+x}{20+x}=\frac{1}{3}[/tex]

Multiply both sides by 20+x

[tex]4+x=\frac{20+x}{3}[/tex]

Multiply both sides by 3

[tex]3(4+x)=20+x[/tex]

Distribute the 3

[tex]12+3x=20+x[/tex]

Subtract x from both sides

[tex]12+2x=20[/tex]

Subtract 12 from both sides

[tex]2x=8[/tex]

Divide both sides by 2

[tex]x=4[/tex]

So Kahn needs to pour 4 more ounces of grape juice, to double check this, since the mixture already has 4 ounces of grape juice, this means the final mixture will have a total of 8 ounces of grape juice concentrate, and a total of 24 ounces, since it already had 16 ounces of water, and 4 ounces of grape juice and now there is 4 more ounces of grape juice being added, so a total of 24 ounces. this means that 8/24 will be grape juice concentrate or in other words: [tex]\frac{1}{3}[/tex] and when you multiply this by 100 (to convert to percent), you get 100/3 or 33 1/3%

Answer: b and d

Substituting in the coordinates of the vertex,

[tex]-4=a(4-2)(4-6)\\\\-4=-4a\\\\a=1[/tex]

Answer:

Invalid statement: There is exactly 1 yellow marble in the box

Step-by-step explanation:

The probability of finding a yellow marble is Py = 1/30, according to the sample. Then, the number of yellow marbles expected to find in the box is:

N x Py > 1 ,

where N = 250 (number of marbles in the box).

Thus, we expect to find more than one yellow marble in the box and the Invalid statement is: "There is exactly 1 yellow marble in the box".

The probability that the company will be fined is 0.1587.

From the information given, it was assumed that μ = 500 ml and σ = 10 ml.

Also, the random sample of 5 bottles has a sample mean under 490 ml.

Here, the probability will be:

= P(x < 490)

= P[(z < (490 - 500)/10]

= P (z < -10/10)

= P(z < -1)

Looking at this under the z table, the probability will be 0.1587

The probability is 0.1587.

The number of different meals possible is 96, computed using combinations.

The combination is a method of choosing a number of articles from a larger set of articles in no particular order.

In the question, we are asked about the different dinner meals possible when a dinner meal is made up of an appetizer, a main course, a dessert, and a drink.

The choices for the appetizer are soup or salad, so the number of ways of choosing an appetizer = 2C1 = 2.

The choices for the main course are chicken, fish, steak, or lobster, so the number of ways of choosing a main course = 4C1 = 4.

The choices for the dessert are ice cream, pie, sorbet, or pastry, so the number of ways of choosing a dessert = 4C1 = 4.

The choices for the drink are coffee, tea, or milk, so the number of ways of choosing a drink = 3C1 = 3.

The total number of ways is the product of all of them.

Therefore, the total number of ways = 2*4*4*3 = 96.

  [tex]r(x)=\dfrac{6x-1}{9x+1}[/tex]

Solve for p(x) = r(x):

[tex]\begin{aligned}p(x) & = r(x)\\\implies 2x-4 & = \dfrac{6x-1}{9x+1}\\(2x-4)(9x+1)&=6x-1\\18x^2+2x-36x-4&=6x-1\\18x^2-40x-3&=0\end{aligned}[/tex]

As the found quadratic equation cannot be factored, use the Quadratic Formula to solve for x:
