When you join 2 consecutive midpoints with a line between them, the length of that line is 1/2 the length of the side opposite the line you just drew.

In other words 24 is 1/2 the length of yz.

Solution

1/2 yz = AB

AB = 24

1/2 yz = 24                 Multiply both sides by 2

2(1/2 yz) = 2*24

yz = 48

Answer

yz = 48

Answer: 0.3, [tex]\frac{6}{20}[/tex], [tex]\frac{3}{10}[/tex], 30%

Step-by-step explanation:

    We will divide wanted outcomes by possible outcomes.

          [tex]\displaystyle \frac{\text{wanted outcomes, green cubes}}{\text{possible outcomes, cubes in bag}} =\frac{6}{20}[/tex]

    Now, we will find four values equivalent to [tex]\frac{6}{20}[/tex]. See attached.

the length of the shorter side is:L  = 13.125cm

In the longer side we have 8 segments.

We know that the side measures 35 cm, then each one of the 8 segments measures:

35cm/8 = 4.375cm

Now, we can see that in the shorter side we have 3 of these segments.

Then the length of the shorter side is:

L  = 3*(4.375cm) = 13.125cm

It is proved in the answer that an exterior angle of the triangle equals the sum of two opposite interior angles.

If a triangle's side is created, the outside angle that results is equal to the product of the two opposite internal angles.

In the figure given below we can see:

∠BCD is the exterior angle of the triangle

∠ABC + ∠BAC + ∠BCA = 180° (Angle sum property of a triangle)

∠BCA + ∠BCD = 180°(Linear pair)

From both equations we can say that:

∠ABC + ∠BAC + ∠BCA  = ∠BCA + ∠BCD

∠ABC + ∠BAC = ∠BCD

Answer:

S = {2, 2, 5, 5, 11}

Step-by-step explanation:

So you can partially build a data set given this information. There is going to be 5 positive numbers and the median is going to be 5 so the data set is going to have 5 in the middle which should look like this

S = {a, b, 5, c, d} where a, b, c, d are the other values. Since it has a mode of 2 and 5 that means that the occurrences of 2 and 5 will be equal, otherwise it would only have 1 mode. and they have to appear at least twice since if they only appeared once, there would either be another mode, or the data set would have 5 modes.

So the data set is going to look like this

S = {2, 2, 5, 5, d}

Now the only thing left to do is calculate d. This is where you use the mean to determine the last value. The mean can be calculated as

(the sum of the data set) / (the amount of values in the data set)

Since we know the mean you can set up an equation to find the value of d

[tex]5 = \frac{2+2+5+5+d}{5}\\5=\frac{14+d}{5}\\25=14+d\\11=d[/tex]

so the last value is 11. This gives you the complete data set of 5 positive integers

S = {2, 2, 5, 5, 11}

T probability of rolling doubles after 45 tosses is 0.156

To do this, we enter the data values in a graphing calculator.

From graphing calculator, we have the following summary:

The regression equation is

y = bx + a

Where

b = SP/SSX = 1375/8250 = 0.16667

a = MY - bMX = 8.7 - (0.17*55) = -0.46667

So, we have:

y = 0.16667x - 0.46667

Approximate

y = 0.167x - 0.467

When the number of tosses is 45, we have:

y = 0.167 * 45 - 0.467

Evaluate

y = 7.048

Approximate

y = 7

45 tosses gives 7 doubles.

So, the probability is:

P = 7/45

Evaluate

P = 0.156

Hence, the probability of rolling doubles after 45 tosses is 0.156

What is a parabola?

A parabola is an approximately U-shaped, mirror-symmetrical planar curve. It corresponds to a number of seemingly unrelated mathematical descriptions, all of which can be shown to define the same curves. One way to describe a parabola is with a point called focus and a line called the directrix.

Equation for a Parabola

The general formula or the equation for representing a parabola is given by,

y² = 4px

Here,  (h,k) being the vertex of the parabola,

y = a(x-h)² + k

x = b(y-k)² + h

The focus of this parabola is given by (p, 0).

The directrix of the parabola is the line drawn perpendicular to the y-axis and traversing the point (-p, 0). The directrix is parallel to the parabola's axis.

[tex]\dfrac{2704m}n = \dfrac{2^4 \times 13^2 \times 13}2 = 2^3 \times 13^3 = 26^3[/tex]

The values of m and n that make 2704 × m/n a perfect cube are:

m = 13 and n = 2.

We have,

We can start by factoring 2704, which is 52².

So we have:

= 2704 × m/n

= 52² × m/n

= (2² × 13²) × m/n

For the expression to be a perfect cube, we need all the prime factors to appear in groups of three.

Since 2 and 13 appear only once each, we need to find another factor that appears twice.

Since m and n are both prime, and the fraction m/n is simplified, there are only two possible values for m and n:

m = 2 and n = 13, or

m = 13 and n = 2

Let's try the first case:

2704 × m/n = 2704 × 2/13 = 416

416 is not a perfect cube, so this case does not work.

Now let's try the second case:

2704 × m/n = 2704 × 13/2 = 17696

17696 is 28³, which is a perfect cube.
