Answer:

y=5

Step-by-step explanation:

2y+8=18

2y=10

y=5

The value y is 5.

Equation is the defined as mathematical statements that have a minimum of two terms containing variables or numbers is equal.

Arithmetic operations can also be specified by the subtract, divide, and multiply built-in functions.

The operator that perform arithmetic operation are called arithmetic operators .

Operators which let do basic mathematical calculations

+ Addition operation : Adds values on either side of the operator.

For example 4 + 2 = 6

- Subtraction operation : Subtracts right hand operand from left hand operand.

for example 4 -2 = 2

* Multiplication operation : Multiplies values on either side of the operator

For example 4*2 = 8

/ Division operation : Divides left hand operand by right hand operand

For example 4/2 = 2

Given equation as:

⇒ 2y + 8 = 18

Substract from 8 both the sides of equation,

⇒ 2y + 8 - 8 = 18 - 8

⇒ 2y = 10

Divided by 2 both the sides of equation,

⇒ y = 5

Hence, the value y is 5.

Answer:

The highest observation =20

The lowest observation = 1

Range of the data = 20-1

= 19(ans)

Answer:

The range is 19

Step-by-step explanation:

To calculate the range of a set of data, you order the numbers from highest to lowest (ex; 20,20,19,18,16,12,12,10,8,8,7,6,4,4,3,1,1) then you subtract the highest number from the lowest number (ex; 20 - 1)

Answer:

C = 65.94 ft and A = 346.185 ft^2

Step-by-step explanation:

r = d/2 = 21/2 = 10.5

let [tex]\pi[/tex] = 3.14

C = 2[tex]\pi[/tex]r

C = 2(3.14)(10.5) = 65.94 ft

A = [tex]\pi[/tex]r^2

A = (3.14)(10.5)^2 = 346.185 ft^2

The solution is: the circumference of the circle is C = 65.94 ft and, the area of the circle A = 346.185 ft^2.

A circle is a closed two-dimensional figure in which the set of all the points in the plane is equidistant from a given point called “centre”. The perimeter around the circle is known as the circumference.

here, we have,

given that,

diameter of the circle = 21

so, we have,

r = d/2

 = 21/2

 = 10.5

let  

π= 3.14

we know that,

the circumference of the circle is:

C = 2rπ

C = 2(3.14)(10.5)

   = 65.94 ft

the area of the circle is:

A =π r^2

A = (3.14)(10.5)^2

  = 346.185 ft^2

Hence, The solution is: the circumference of the circle is C = 65.94 ft and, the area of the circle A = 346.185 ft^2.

Answer:

[tex]y=\frac{1}{2} x+8[/tex]

Step-by-step explanation:

Hi there!

Slope-intercept form: [tex]y=mx+b[/tex] where m is the slope and b is the y-intercept (the value of y when the line crosses the y-axis)

1) Determine the slope (m)

Perpendicular lines will always have slopes that are negative reciprocals of each other. For example, two perpendicular lines might have slopes of 3 and -1/3.

After observing the equation y=-2x-5, we can conclude that the slope is -2. Therefore, a line perpendicular to this line would have a slope of 1/2. Plug this into [tex]y=mx+b[/tex]:

[tex]y=\frac{1}{2} x+b[/tex]

2) Determine the y-intercept (b)

[tex]y=\frac{1}{2} x+b[/tex]

Plug in the given point (-4,6)

[tex]6=\frac{1}{2}(-4)+b\\6=-2+b[/tex]

Add 2 to both sides

[tex]6+2=-2+b+2\\8=b[/tex]

Therefore, the y-intercept is 8. Plug this back into [tex]y=\frac{1}{2} x+b[/tex]:

[tex]y=\frac{1}{2} x+8[/tex]

Given:

Total number of students = 27

Students who play basketball = 7

Student who play baseball = 18

Students who play neither sports = 7

To find:

The probability the student chosen at randomly from the class plays both basketball and base ball.

Solution:

Let the following events,

A : Student plays basketball

B : Student plays baseball

U : Union set or all students.

Then according to given information,

[tex]n(U)=27[/tex]

[tex]n(A)=7[/tex]

[tex]n(B)=18[/tex]

[tex]n(A'\cap B')=7[/tex]

We know that,

[tex]n(A\cup B)=n(U)-n(A'\cap B')[/tex]

[tex]n(A\cup B)=27-7[/tex]

[tex]n(A\cup B)=20[/tex]

Now,

[tex]n(A\cup B)=n(A)+n(B)-n(A\cap B)[/tex]

[tex]20=7+18-n(A\cap B)[/tex]

[tex]n(A\cap B)=7+18-20[/tex]

[tex]n(A\cap B)=25-20[/tex]

[tex]n(A\cap B)=5[/tex]

It means, the number of students who play both sports is 5.

The probability the student chosen at randomly from the class plays both basketball and base ball is

[tex]\text{Probability}=\dfrac{\text{Number of students who play both sports}}{\text{Total number of students}}[/tex]

[tex]\text{Probability}=\dfrac{5}{27}[/tex]

Therefore, the required probability is [tex]\dfrac{5}{27}[/tex].

Answer:

B. (5/6)^2

Step-by-step explanation:

A. 2^3

= 2 × 2 × 2

= 8

The base is 2

Therefore, the expression is greater than the base

B. (5/6)^2

= 5/6 × 5/6

= 5*5 / 6*6

= 25/36

Base = 5/6 = 0.833

Expression =25/36 = 0.694

Therefore, the expression is less than the base

C. 3^1

= 3

The base is 3

Therefore, the expression is equal to the base

D. 4^4

= 4 * 4 * 4 * 4

= 256

The base is 4

Therefore, the expression is greater than the base

The correct answer is B. (5/6)^2

So add up three of it so the answer is 36

If function f(x)= x² then g(x) is  -x² - 3 , option A is correct.

A relation is a function if it has only One y-value for each x-value.

The reflection in the x-axis changes the sign of the y-coordinate. So, the reflection of f(x) = x² in the x-axis is g(x) = -x².

Secondly, the downward shift of 3 units means subtracting 3 from the y-coordinate.

So, the transformation applied to f(x) to get g(x) is reflection in the x-axis followed by a downward shift of 3 units.

g(x) = -x² - 3 is the result of applying a reflection in the x-axis followed by a downward shift of 3 units to the function f(x) = x².

Hence, if function f(x)= x² then g(x) is  -x² - 3 , option A is correct.

Answer:

55 cm²

Step-by-step explanation:

In a parallelogram, the top base is equal to the bottom base (and the sides are equal to each other too!)

So the top and bottom base are both 9, and the left and right sides are both 5.

So, to solve, we need to use the equation:

(4 + 1) * (9 + 2) = 5 * 11 = 55 cm²

The straight line distance between the start and finish point is required.

The straight line distance is 5.7 miles.

a = Distance traveled north = 4 miles

b = Distance traveled east = 4 miles

c = Straight line distance

The angle between the two paths is ninety degrees so, the Pythagoras theorem can be applied here.

Applying the Pythagoras theorem

[tex]c=\sqrt{a^2+b^2}\\\Rightarrow c=\sqrt{4^2+4^2}\\\Rightarrow c=4\sqrt{2}\\\Rightarrow c=5.7\ \text{miles}[/tex]
