Answer:

the probability of getting an even numbers out of this set is 1/2

Step-by-step explanation:

The set of numbers are: 10

1,2,3,4,5,6,7,8,9,10

Even Numbers: 5

2,4,6,8,10

Probability = [tex]\frac{NumberOfFavourableOutcomes}{TotalNumberOfOutcomes}[/tex]

P = [tex]\frac{Even Numbers}{Total Numbers}[/tex]

P = [tex]\frac{5}{10}[/tex]

P = [tex]\frac{1}{2}[/tex]

So, the probability of getting an even numbers out of this set is 1/2

Answer:

The probability of this set of numbers is 1/2.

Step-by-step explanation:

Probability is the odds of an event happening. It is expressed by writing it as a fraction, decimal, or a percent.

The formula for probability is the number of favorable outcomes divided by the total number of outcomes. In this case, we have odd and even numbers. The even numbers in this set are 2, 4, 6, 8, and 10.

These are the favorable outcomes.

Since there are 5 even numbers, there are 5 favorable outcomes.

There are total of 10 outcomes. Therefore P(Even number)= 5/10.

Don't forget to always simplify. You can divide the numerator and denominator by 5. 5 divided 5 is 1 and 10 divided by 5 is 2.

Therefore, the probability of choosing an even number from this set of numbers is 1/2.

I hope this helps, and I hope you enjoy the rest of your day!

Answer:

Option 1

Step-by-step explanation:

ABCD is a parallelogram, Julie wants to prove that ABCD is also a square.

Remember that a parallelogram has opposite sides equal.

So,

AB ≅ CD

AD ≅ BC

The 4 triangles are congruent. The bases of the triangles are vertically opposite to each other and are congruent. We can use the definition of a parallelogram to prove AB ≅ BC.

Answer:

[tex] y = -\dfrac{1}{28}x + 15 [/tex]

Step-by-step explanation:

The car uses 15 gallons of gasoline to drive 420 miles.

(15 gal)/(420 mi) = 1/28 gal/mi

The car uses 1/28 gallon of gasoline per mile.

y = mx + b

When x = 0, at the start of the drive, the car has 15 gallons of gasoline.

y = mx + 15

Then for every mile it travels, the amount  of gasoline goes down by 1/28 gal. For x miles of travel, it uses 1/28 * x gallons of gasoline.

[tex] y = -\dfrac{1}{28}x + 15 [/tex]

Answer:

[tex]\left(q-\dfrac{23}{2}\right)^2[/tex]

Step-by-step explanation:

Given the expression: [tex]q^2-23q[/tex]

To complete the square, we follow these steps:

Step 1: Identify the coefficient of q

Coefficient of q=-23

Step 2: Divide the coefficient of q by 2

[tex]=-\dfrac{23}{2}[/tex]

Step 3: Square your result from step 2 and add it to the equation

This gives us: [tex]q^2-23q+\left(-\dfrac{23}{2}\right)^2[/tex]

We have now completed the square.

Step 4: Write the result as a binomial square.

To write it as a binomial square, pick the variable and add the term in the bracket.

Therefore:

[tex]q^2-23q+\left(-\dfrac{23}{2}\right)^2=\left(q-\dfrac{23}{2}\right)^2[/tex]

The perfect square form of the given expression will be [tex](q-\dfrac{23}{2})^2[/tex].

The given expression is [tex]q^2-23q[/tex].

It is required to write the given expression as a perfect square polynomial or trinomial.

We will use the identity [tex](a+b)^2=a^2+2ab+b^2[/tex].

So, the first term from the given expression will be [tex]a=q[/tex].

To find the second term b, divide the 2nd term of the given expression by 2,

[tex]b=\dfrac{-23}{2}[/tex]

So, the given expression can be written in the perfect square form as,

[tex]a^2+2ab+b^2=q^2-23q+(\dfrac{-23}{2})^2\\=(q-\dfrac{23}{2})(q-\dfrac{23}{2})\\=(q-\dfrac{23}{2})^2[/tex]

Therefore, the perfect square form of the given expression will be [tex](q-\dfrac{23}{2})^2[/tex].

Step-by-step explanation:

Solution:-

- We will use the basic formulas for calculating the volumes of two solid bodies.

- The volume of a cylinder ( V_l ) is represented by:

                                  [tex]V_c = \pi *r^2*h[/tex]

- Similarly, the volume of cone ( V_c ) is represented by:

                                  [tex]V_c = \frac{1}{3}*\pi *r^2 * h[/tex]

Where,

               r : The radius of cylinder / radius of circular base of the cone

               h : The height of the cylinder / cone

- We will investigate the correlation between the volume of each of the two bodies wit the radius ( r ). We will assume that the height of cylinder/cone as a constant.

- We will represent a proportionality of Volume ( V ) with respect to ( r ):

                                  [tex]V = C*r^2[/tex]

Where,

            C: The constant of proportionality

- Hence the proportional relation is expressed as:

                                 V∝ r^2

- The volume ( V ) is proportional to the square of the radius. Now we will see the effect of multiplying the radius ( r ) with a positive number ( a ) on the volume of either of the two bodies:

                                [tex]V = C*(a*r)^2\\\\V = C*a^2*r^2[/tex]

- Hence, we see a general rule frm above relation that multiplying the result by square of the multiple ( a^2 ) will give us the equivalent result as multiplying a multiple ( a ) with radius ( r ).

- Hence, the relations for each of the two bodies becomes:

                              [tex]V = (\frac{1}{3} \pi *r^2*h)*a^2[/tex]

                                          &

                              [tex]V = ( \pi *r^2*h)*a^2[/tex]

Step-by-step explanation:

The given data is represented in the attachment.

a) Explain why yields from one type of corn are not independent of the yields from the other type of corn.

Yields from one type of corn are not independent of the yields from the other type of corn because, as the corns are planted in two similar plots, they could compete during watering process, even the amount of nutrients shared and the type of air. This means one corn may get more nutrients than the other. Therefore, they are not independent (they are dependent).

b) Based on the summary statistics, GM is expected to more likely obtain yield greater than 123, because 123 is greater than mean for regular corn but less than mean for GM corn.

Thus,

P(yield>123|GM)>0.5; and P(yield>123|Regular)<0.5

Answer:

cos34°

sin56°

Step-by-step explanation:

Sin(2x+42)= sin90-(3x+13)

Sin(2x+42) = sin(90-13-3x)

Sin(2x+42) = sin(77-3x)

2x + 42 = 77-3x

5x. = 35

X = 7

If x = 7

cos(3x+13) = cos((3*7)+13)

cos(3x+13) = cos(21+13)

cos(3x+13)= cos34

And

sin(2x+42) = sin((2*7)+42)

sin(2x+42)= sin (14+42)

sin(2x+42) = sin56

Answer:

On a coordinate plane, a step graph has horizontal segments that are each 1 unit long. The left end of each segment is a closed circle. The right end of each segment is an open circle. The left-most segment goes from (negative 3, negative 5) to (negative 2, negative 5). Each segment is 1 unit higher and 1 unit farther to the right than the previous segment. The right-most segment goes from (4, 2) to (5, 2).

Step-by-step explanation:

The floor function graphs as horizontal segments 1 unit long, each 1 unit up from the segment to its left. It will have a closed circle at the left end of the segment, and an open circle at the right end.

Since 2 is subtracted from the floor of the x-value, the closed circle at the left end of the segment will have coordinates (x, x-2). The only offered choice meeting that condition is the 3rd choice listed here.

Step-by-step explanation:

Comenzaremos por dividir el triángulo en dos partes y definir H, como en la figura adjunta.

Aplicando el teorema de Tales, sabemos que:

[tex]\dfrac{l/2}{H}=\dfrac{x/2}{h}\\\\\\\dfrac{l}{H}=\dfrac{x}{h}[/tex]

También sabemos que, dado que el tirángulo menor es la mitad que el triángulo mayor, la relación entre áreas es:

[tex]\dfrac{A}{A_x}=\dfrac{lH/2}{xh/2}=\dfrac{lH}{xh}=2[/tex]

Dado que formamos dos triángulos rectángulos, podemos despejar el valor de H como:

[tex](l/2)^2+H^2=l^2\\\\H^2=l^2-(l/2)^2=10^2-5^2=100-25=75\\\\H^2=\sqrt{75}[/tex]

Podemos entonces despejar x de la siguiente manera:

[tex]h=\dfrac{H}{l}\cdot x=\dfrac{lH}{2x}\\\\\\2x^2\dfrac{H}{l}=lH\\\\\\2x^2=l^2\\\\\\x=\dfrac{l}{\sqrt{2}}=\dfrac{10}{\sqrt{2}}\approx7.07[/tex]
