Answer:

5/28

Step-by-step explanation:

First you multiply across,

5 · 2 = 10

8 · 7 = 56

Then after multiplying, you will get the fraction, 10/56.

You can simplify that into 5/28.

The distribution of the probability of the given data is a Positive Skewed Probability distribution.

Given to us

A spinner is divided into five sections numbered 1 through 5. Juana records the number the spinner lands on for each of the 50 spins. She computes and graphs the relative frequencies for each number

It is a type of distribution in which the distribution has a constant probability, therefore, the probability of each event occurring is equal.

Symmetric distribution is the type of distribution where the left side of the distribution and the right side of the distribution are mirror images to each other, therefore, they are symmetrical.

Negatively Skewed Probability distribution is a type of distribution of the probability where the right side(tail) of the distribution is more concentrated than the right side.

Positive Skewed Probability distribution is a type of distribution of the probability where the left side of the distribution is more concentrated than the right side.

Since in the given graph probability of every number occurring from 2 to 5 is equal to 0.12(12%), while the probability of number 1 occurring is 0.5(50%).

Thus, the distribution of the probability is towards the right end of the graph.

Hence, the distribution of the probability of the given data is a Positive Skewed Probability distribution.

Step-by-step explanation:

Senior tickets (x)

Child tickets (y)

First day:  3x + 5y = 70

second day: 12x + 12y = 216

Solve the system of equations (use elimination)

Multiply first equation by -4   -4(3x + 5y = 70),  which makes it

-12x - 20y = -280

(+)12x + 12y = 216    add to second equation

-8y = -64

divide by -8.    y = 8

Plugin the y value to either equation ( I will choose first equation)

3x + 5(8) =70

3x+ 40 = 70

3x = 30

x = 10

Senior tickets are $10, child tickets are $8

Answer:

in the figure four quadrants each of radius 2 m are removed from a rectangle.

I have attached the required figure, assuming the sides of a rectangle based on given measurement of quadrants.

Let the sides of a rectangle be 2 m × 4 m.

The radius of quadrant is 2 m ( given )

From given, we have

Area of figure = Area of 4 quadrants - Area of rectangle .

= 4 × π/4 × r² - l × w

= 4 × π/4 × 2² - 2 × 4

= 3.14 × 4 - 8

= 12.4 - 8

= 4.4 m²

Therefore, the area of the figure is 4.4 m²

Perimeter of figure = Perimeter of 4 quadrants - Perimeter of rectangle

= 4 × [ 0.5πr + 2r ] - 2 ( l + w )

=  4 × [ 0.5 × 3.14 × 2 + 2 × 2 ] - 2 ( 4 + 2 )

=  4 × [ 3.14 + 4 ] - 2 (6)

= 28.56 - 12

= 16.56 m

the perimeter of the figure is 16.56 m

Answer:

the third one

Step-by-step explanation:

the square root of 25 is 5. 5+2 = 7.

this is a rational number (the set of all integers and fractions).

the other 2 portions contain at least one element that is not rational. and so the sum with such a number is not rational.

45 and 7 are no square numbers, and therefore the square root of these numbers contains a neverending chain of digits after the decimal point without having any repeating pattern. these are real numbers but not rational numbers.

Answer:

The answer is B

the shaded part is below which signifies a less than sign

so you can cross out options A and C

now make y=0

for option B, it will give √Xless than or equal to √4

for option D, it will give √4 less than or equal to √x

to bring √x to the other side, the inequality sign will change to greater than

Therefore the answer is B

Answer:

the answer is 11.

if 16 inches of wire cost 48 cents your goal i to figure out how many inches of wire cots 33 cents to do so you have to find out how many cents each inch is. to do that you have to divide 48 by 16 and you get 3 so that mean that 1 inch costs 3 cents. after you figure that out you do 33 divided by 3 and you get 11. the answer is 11 inches costs 33 cents.

m = -1

Step-by-step explanation:

Formula we'll use: [tex]\frac{y2}{x2} -\frac{y1}{x1} =m[/tex]

m = slope.

y2 = -4

x2 = -5

y1 = 6

x1 = 5

Substitute -4, -5, 6, 5 into the formula:

[tex]\frac{-4}{-5} -\frac{6}{5} =[/tex]

Subtract both top and bottom:

m = -10/-10

m = -1

1,905.63 is the correct answer

The perimeter of a shape is the sum of its side lengths

The corresponding side length for shape B is 20 feet

The length-perimeter ratio is given as:

Ratio = Length : Perimeter

For both shapes, we have:

12 : 36 = Length : 60

Express as fraction

[tex]\frac{12}{36} = \frac{Length}{60}[/tex]

Multiply both sides by 60

[tex]Length = \frac{12}{36} * 60[/tex]

[tex]Length =20[/tex]

Hence, the corresponding side length for shape B is 20 feet

Answer:

All real numbers

Step-by-step explanation:

Since x=2y+5, and 2x-4y=10, substitute 2y+5 for x into 2x-4y=10

2(2y+5)-4y=10

Use distributive prop.

4y+10-4y=10

10=10

Since both sides of the equation are always equivalent,

All real numbers work, since the two equations are the same line.
