Step-by-step explanation:

Using formula y=kxz

so,

24=k*4*3

k=2

so if we put x=12 and z=4,

y=2*12*4

y=48

Answer:

[tex]1 + 1 = 2[/tex]

Step-by-step explanation:

1 + 1 is equal to 2 because it is- at least that's what we believe the answer to be. It doesn't have to, but it is just what we as humans have come to recognize because it is internationally accepted.

Heck, you don't need to be a genius to understand that when you inherently have exactly one more of a thing, you have more of it. Numbers are just a way to represent more (or less if we're talking negatives). Now, we'll probably never understand why mathematics is so beautifully synchronized with our world, but it is, and we as a sentient species have come to recognize that for the longest time.

Numbers are abstract, as long as you are consistent, anything can be a number if you give it value. [tex]1+1[/tex] doesn't have to equal [tex]2[/tex], if we wanted we could make it equal to [tex]:)[/tex]. [tex]1 + 1 =\ :)[/tex]

Whether we are solving basic algebra:

[tex]:)x + 4 = 10\\:)x = 6\\x = \frac{6}{:)} =3[/tex]

Or calculating integrals:

[tex]\int\limits^{0.5}_{0} {8xe^{:)x}} \, dx\\= \frac{xe^{:)x}}{:)}-\int\limits{\frac{e^{:)x}}{:)}} \, dx\\= 4xe^{:)x} - :)e^{:)x} + C = (4x-:))e^{:)x} + C\\=(4x-:))e^{:)x}|^{0.5}_{0}\\= (4(0.5)-:))e^{:)(0.5)} - (4(0)-:))e^{:)(0)}\\= :)[/tex]

[tex]1+1[/tex] will always be whatever [tex]1+1[/tex] is.

Hopefully, I didn't get too philosophical lol.

Answer:

you need to width x height x length b

Step-by-step explanation:

Length, width, and height are measurements that allow us to indicate the volume of geometric bodies. The length (6 cm) and the width (10 cm) correspond to the horizontal dimension. On the other hand, the height      (5 cm)refers to the vertical dimension.

Answer:

x=12

Step-by-step explanation:

Every triangle has interior degrees that all together add up to 180. We already know we have 50 degrees and 75 degrees, so we can subtract that to see how much we have left to work with. If we do that, we get 55 degrees left. Now, we have to set up a two step equation to find x:

5x-5=55

The first thing to do is to add 5 to both sides to get rid of -5:

5x-5=55

   +5  +5

    __ __

     0   60

So now, it's 5x=60

Now, we have to isolate x. To do this, we have to divide both sides by 5. If you do this, you get:

x=12

Hope this helped!

Answer: b) x = 12

Step-by-step explanation:

   The sum of a triangle's angles add up to 180°. We will add together all the angles, set them equal to 180°, and then solve.

Given:

(50°) + (75°) + (5x - 5°) = 180°

Combine similar terms:

120° + 5x = 180°

Subtract 120° from both sides of the equation:

5x = 60°

Divide both sides of the equation by 5:

x = 12

       Your answer is;

           b) x = 12

Answer:

5 per comic book and 12 per computer game hope this helps.

Answer:

Step-by-step explanation:

8x + 3y = 76

x  + 3y = 41

8x + 3y = 76

-x - 3y = -41

7x = 35

x = $5 comic book

3y + 5 = 41

3y = 36

y = $12 computer game

Step-by-step explanation:

Given the five summary of a data set:

45 - min

52 - Q1

56 - Median

61 - Q3

69- Max

Thus, any number less than Q1-(1.5×IQR)

, or any number that is greater than

Q3+ (1.5 × IQR) would be considered an outlier.

The IQR of the data set = Q3 - Q1 = 61-

52 = 9

Thus,

Q1- (1.5 × IQR) =52- (1.5* 9) = 52 - 13.5=38.5

Therefore, an observation is considered

an outlier if it is below: 38.5

Q3 + (1.5 * 1QR) = 61 + (1.5 * 9) =61+13.5 =74.5

Therefore, an observation is considered

an outlier if it is above: 74.5

The signs are different so we subtract and take the sign of the larger

5 - 2 1/3

Borr from the 5

Step-by-step explanation:

The probability that they have a mean salary between $40,000 and $50,000 is 0.01.

A z-test is a statistical test to determine whether two population means are different when the variances are known and the sample size is large.

The z-score for 40,000 is

= (40,000 - 66000) / (14,000 / √4)

= -26000/7000

= -3.714, P- value is 0.000102

The z-score for 50,000

= (50,000 - 66,000) / (14,000 / √4)

=-2.285, P- value is 0.0111564

P(40,000 < x < 50,000) = P(  -3.714< z < -2.285)

So,

= P(50,000)-P(40,000)

= 0.0111564-0.000102

=0.011

Hence, the probability that they have a mean salary between $40,000 and $50,000 is 0.01.

The equation that best represent the volume of the cylinder in cubic inches is V = π4²h.

A cylinder is simply a 3-dimensional shape having two parallel circular bases joined by a curved surface.

The volume of a cylinder is expressed as;

V = π × r² × h

Where r is radius of the circular base, h is height and π is constant pi.

Given that;

V = π × r² × h

V = π × (4)² × h

V = π4²h

Therefore, the equation that best represent the volume of the cylinder in cubic inches is V = π4²h.

The height of a trapezoid is the distance between the parallel bases.

__

Here, one base lies on the horizontal line y=5, and the other lies on the horizontal line y = -6. The distance between them is ...

  5 -(-6) = 5 +6 = 11

You can also find this distance by counting the grid squares between the two parallel lines.

The height of the trapezoid is 11 units.
