Answer:

The percentage of all animals at fair Y that are goats is greater than the percentage of all animals at fair X that are goats.

Step-by-step explanation:

From the bar chart,  we can see that 100 goats were present at fair X and Y

Let us now calculate the percentage of goats at each fair:

Fair X = 100/645 * 100 = 15.5%

Fair Y =100/590 *100 = 16.9 %

Hence there was a greater percentage of goats at fair Y than at fair X.

The bar chart is missing and so i have attached it.

Also, the question is incomplete and the missing part of the question is;

Which of the following statements is supported by the bar chart?

a) The total number of cows, pigs, and horses combined is less at fair X than at fair Y.

b) Fair X has at least 20 more chickens than fair Y.

c) At fair X, the number of sheep is twice the number of horses.

d) The percentage of all animals at fair Y that are goats is equal to the percentage of all animals at fair X that are goats.

e) The percentage of all animals at fair Y that are goats is greater than the percentage of all animals at fair X that are goats.

The only Statement that supports the bar chart is statement E.

At fair X: Cows = 50, Pigs =60, Horses = 80. Total = 50 + 60 + 80 = 190

At fair Y:  Cows = 60, Pigs = 80, Horses = 40. Total = 60 + 80 + 40 = 180

Total in fair X is greater than total in fair Y. Therefore statement in question is false.

At fair X; chickens = 90

At fair Y; chickens = 80

Difference = 90 - 80 = 10

Thus,statement in question is wrong.

Sheeps = 140

Horses = 80

Twice number of horses is not same as sheep. Thus, statement in question is wrong.

Percentage that are goats = 100/590 × 100 = 16.95%

Total number of animals at fair X = 50 + 60 + 80 + 90 + 100 + 125 + 140 = 645

Percentage that are goats = 100/645 × 100 = 15.5%

The percentages are not equal and so the statement in the question is wrong.

Answer:

supplementary

Step-by-step explanation:

we have,

3x+15+2x=180

=> 5x +15 = 180

=> 5x = 180-15

=> 5x = 165

=> x = 165/5

=> x= 33

so, 3x+15 = 3*33+15

=> 99+15

=>114

2x = 2*33

=> 99

now we can check if these angles are supplementary

114 + 99 = 180

so, they are supplementary

The measure of the angle of refraction is 22 degress, the correct option is A.

The angle made by a refracted ray with a perpendicular to the refracting surface.

Given

An incident ray of light strikes water at an angle of 30°.

The index of refraction of air is 1. 0003, and the index of refraction of water is 1. 33.

In order to determine the angle of the refracted ray, we may apply Snell's law, which states that the ratio of the sines of the angles of incidence and refraction is constant for a given wave when it passes through two different media.

The angle of the refraction is given by;

[tex]\rm 1.0003 \times sin(30) = 1.33 \times sin(\phi)\\\\ \rm 1.0003 \times 0.5 = 1.33 \times sin(\phi)\\\\Sin\phi=\rm \dfrac{1.0003 \times 0.5 }{1.33}\\\\Sin\phi=0.37\\\\\phi = 22[/tex]

Hence, the measure of the angle of refraction is 22 degress.

The equation for the volume of the prism will be given as  V=x^3+3x^2

The volume of the prism is given by the following formula

[tex]\rm Volume = Width\times Length\times hieght[/tex]

Here we have a condition in the question that

The height of a right rectangular prism is 3 units greater than the length

[tex]h=x+3[/tex]

length will be l = x

The width will be w=x

now by putting the value in the formula we get

[tex]\rm Volume = w\times L\times h[/tex]

[tex]\rm Volume = x \times x \times (x+3)[/tex]

[tex]\rm Volume = x^3+3x^2[/tex]

Thus the equation for the volume of the prism will be given as  [tex]V=x^3+3x^2[/tex]

Answer:

The mean is the average of a data set. You can find the mean by adding all of the numbers in the guven set of data and then divide by the total number of values in a set.

Step-by-step explanation:

for example:

2, 6, 8, 13, 16, 11, 7

add all of these numbers together

the total would be 63

there are 7 numbers in the data set so you would divide 63 by 7

the mean of the data set would be 9

Answer:

The average of the numbers is the mean. After adding up all the numbers, divide by the number of numbers. You must add all the values in a data set together and divide by the number of values in the collection to determine the mean. The end product is yours!

Answer:

D. Undefined term

Step-by-step explanation:

Points are flat surfaces, named using a capital letter, and have no depth or width because they are on a FLAT plane. Just like lines are named "line A", are on a flat surface, and have no depth or width, points also share these characteristics because they are all on a plane. However, a point is not an undefined term, it is a defined term.

A point is a geometric feature used for the definition of geometric objects

The option which is not a characteristic of a point is option A:

A. Flat surface

The reason for the above selection is as follows:

A point in Euclidean geometry is a concept that defines an exact spatial location

The characteristics of a point are:

A flat surface is defined by three noncolinear points

Therefore;

The given option which is not a characteristic of a point is therefore option A. Flat surface

Answer:

2.25

Step-by-step explanation:

Notice how the common ratio is -1/3, which means the series passes part 1 of the convergence test because -1/3 is in between -1 and 1.

We can also represent this as a summation series of

[tex]Σ3( - \frac{1}{3} ) {}^{n - 1} [/tex]

Since we can represent this a summation series, we can use that convergent value is equal to

[tex] \frac{a _{1} }{1 - r} [/tex]

where a1 is initial term and r is common ratio.

R is -1/3

A1 is 3.

[tex] \frac{3}{1 - \frac{ - 1}{3} } = \frac{3}{ \frac{4}{3} } = 2.25[/tex]

So the answer is 2.25
