There are 84 sets of pictures she can post on her wall.

Since Alyssa has taken a picture with every single athlete individually. It means she has taken 9 pictures.

Now she wants to post 3 pictures on her wall.

We need to use Combination for arranging pictures. A combination is a mathematical technique that determines the number of possible arrangements in a collection of items where the order of the selection does not matter. In combinations, we can select the items in any order.

Therefore, The number of different sets of pictures = Selecting 3 pictures from a set of 9 pictures

9C3  =  (9!)/((9-3)!*3!)

(9*8*7)(3*2*1)= 84 ways

No, the friend is not correct.

The equation of a line is a single b of numerous points on the line. The general form of the equation of a line is of the form ax + by + c = 0 and any point on the line satisfies this equation.

slope= 2/4= 1/2

Now,

y-(-2)= 1/2(x-0)

y+2= 1/2x

y= 1/2x - 2

The sequence of transformation is; B. A translation 2 units to the right and 1 unit up followed by a counter-clockwise rotation 90° about the origin.

From the given image in the transformation, we can see that the pre image which is the original image is on the right hand side while the image after transformation is on the left hand side.

Now it will be noticed that in the pre image, all the x and y coordinates are positive while the image after transformation has all the x-coordinates as negative with the y-coordinates as positive.

The simplified equation equivalent to the total distance in miles is given as,

[tex]x^{2} +5x[/tex]

What is the equation representing the total distance?

It is given that in a road test of a geared bike,

The distance covered on a flat road = (3x - 2)

The distance covered uphill = (x² - 5)

The distance covered downhill = (2x + 7)

Total distance covered in miles as equation,

(3x - 2) + (x² - 5) + (2x + 7)

= 3x - 2 + x² -5 + 2x + 7

= 5x - 7 + x² + 7

= x² + 5x

Thus, the final equation representing the total distance covered in miles by the bike is (x² + 5x)

Answer:

60 degrees

Step-by-step explanation:

Since all three sides are the same length, all three angles must be the same size.  This means the triangle is an equilateral triangle

The angles are 60 degrees

Answer:

Hello! The answer is 60°.

Step-by-step explanation:

As marked by the dashes on each side, the sides are congruent. If the sides are congruent, this means that the angle measures are equal.

Having three equal sides is an equilateral triangle, and the total angle measure sum is 180.

To find the measure of angle y, you will have to divide the total angle measure by the number of angles:

180 ÷ 3 = 60

The measure of angle y = 60°

240 students

Step-by-step explanation:

     To find the minimum number of students, we have to find the LCM of 10, 12, 16

10 = 2 * 5

12 = 2 * 2 * 3

16 = 2 * 2 * 2 * 2

LCM = 2 * 2 *  2 * 2 * 3 * 5

       = 240

Answer:

8π ft

Step-by-step explanation:

Arc length = 2πr ( θ / 360 )

Here,

θ = 90

r = 90 ft

Arc length = 2πr ( θ / 360 )

Arc length = ( 2π * 16 ) ( 90 / 360 )

                 = ( 2π * 16 ) ( 1 / 4 )

                 = ( 2π * 16 )/4

                 = 2π * 4

Arc length = 8π ft

Answer:

B

Step-by-step explanation:

the arc length is calculated as

arc = circumference of circle × fraction of circle

     = 2πr × [tex]\frac{90}{360}[/tex]

     = 2π × 16 × [tex]\frac{1}{4}[/tex]

    = 2π × 16 × [tex]\frac{1}{4}[/tex]

    = 32π × [tex]\frac{1}{4}[/tex]

It would take 1.5 seconds for the diver standing on a spring board 24 feet above the pool to hit the water.

An equation is an expression that shows the relationship between two or more numbers and variables.

Given that d represent the height of the diver above the water and t is the time in seconds.

d(t) = -16(2t - 3)(t + 1)

The diver hit the water at d(t) = 0, hence:

0 = -16(2t - 3)(t + 1)

2t - 3 = 0; or t + 1 = 0

t = 1.5 seconds

The probability that the mean weight of the sample babies would be less than 3631 grams is 0.1591 or 15.91%.

The mean weight of the babies (μ) = 3685 grams.

The variance (σ²) = 330625.

Therefore, the standard deviation (σ) = √330625 = 575.

The sample size (n) = 113.

The sample mean = μ - 3685 grams.

The sample standard deviation (s) = σ/√n = 575/√113 = 54.09145.

We are asked to find the probability that the mean weight of the sample babies is less than 3631 grams, that is,

P(X < 3631)  = P(Z < {(3631 - 3685)/54.09145})

Using the formula: Z = (x - μ)/s,

or, P(Z < -0.9983) = 0.1591 or 15.91%.

From the table of area under the z-score.

P(X < 3631) can also be calculated using calculator function:

Normalcdf(-100000000,3631,3685,54.0195), which gives the value 0.1591 or 15.91%.

The first proof that organic molecules required for life might be created from inorganic elements was supplied by the Miller-Urey experiment.

Answer:

28 legs are on the floor once again

There are no legs on the floor.

Hence answer is zero.

According to the question,

For 2 dogs: Each dog has 4 legs.

Therefore, 2 dogs have a total of 8 legs.

For 4 horses: Each horse has 4 legs.

Therefore, 4 horses have a total of 16 legs.

For 1 giraffe: A giraffe has 4 legs.

For 1 duck: A duck has 2 legs.

For 3 hens: Each hen has 2 legs.

Therefore, 3 hens have a total of 6 legs.

To get the total number of legs on the bed,

we simply add up all the legs of the animals on the bed,

⇒ 8 legs + 16 legs + 4 legs + 2 legs + 6 legs = 36 legs.

Now, to get the number of legs on the floor,

We need to subtract the number of legs on the bed from the total number of legs of all the animals,

For 2 dogs with a total of 8 legs.

For 4 horses with a total of 16 legs.

For 1 giraffe with 4 legs.

For 1 duck with 2 legs.

For 3 hens with a total of 6 legs.

So, the total number of legs of all the animals is,

⇒ 8 legs + 16 legs + 4 legs + 2 legs + 6 legs = 36 legs.

Since all the animals are on the bed,

There are no legs on the floor.
