if a=2 what is the value of a + 6 ?

Answer:

A. 29

B. 22

C. 36

Step-by-step explanation:

To find the median, you have to put the numbers in order from least to greatest which would be 18, 19, 22, 28, 28, 30, 32, 36, 37, 42. Then you find the number in the middle, and there are 10 numbers. So, you split them in half and 18, 19, 22, 28, 28 would be on one half, and 30, 32, 36, 37, 42 would be on the second half. The middle of 28 and 30 is 29, so that is your median.

To find the lower quartile, you have to divide the numbers into two sides with the lowest numbers on one side and the highest numbers on the other. Since there are 10 numbers, there will be 5 on each side. On the lowest number side there will be 18, 19, 22, 28, 28. To find the lower quartile, you find the middle number of the 5 numbers. 22 is in the middle, so that is the lower quartile.

To find the upper quartile, you have to take the highest numbers which are 30, 32, 36, 37, 42. Then you find the middle number, just like finding the lower quartile. The number in the middle is 36, so that is the upper quartile.

Answer:

C) 162

Step-by-step explanation:

Use PEMDAS (Parentheses, Exponents, Multiply/Divide{Left to Right}, Add/Subtract{Left to Right})

1. Parentheses

2. Exponents

None

3. Multiply/Divide{Left to Right}

[tex]2*81=162[/tex]

4. Final Answer

[tex]2(3^4)=162[/tex]

Answer:

A

Step-by-step explanation:

Simply put if it's 50-50 then it just is what it is

The student's error is that d) Data is never symmetric, so this assumption is incorrect.

Median of a data set is the element in the middle if the data are arranged in increasing or decreasing order.

Given that,

A student claims that 50% of a sample of data is less than the median and 50% of data is greater than the median, therefore the data is symmetric.

In a symmetric distribution, the left hand side and the right hand side of the median will be equal.

That is, the left points and the right points are equal.

Hence the correct option is d) Data is never symmetric, so this assumption is incorrect.

130 people's bought floor seats ...

→ First , we need to identify and define the unknown terms.

F: # of floor seats sold

G: # of grandstand seats sold

• F + G = 210 {210 is the total number of seats sold}

• 5F + 2G = 660 {the 5 , 2 and 660 refer to amounts of dollars} .

→ We now have two equations in two unknowns , which we should be able to solve.

→ Let's solve the first equation for G, and then substitute the value of G into the second equation , so that we have will have a single equation with only F as the unknown ...;

→ F represents the number for which we are looking: The number of floor seats sold.

F + G = 210

F - F + G = 210 - F

G = 210 - P

→ 2F+ 5G = 660

→ 2F + 5(210 - F) = 660

→ 2F + 1050 - 5F = 660

→ - 3F + 1050 = 660

→ - 3F + 1050 - 1050 = 660 - 1050

→ - 3F = - 390

→ F = - 390 / - 3 = 130

→ F = 130

• Hence , 130 people's bought floor seats ...

Step-by-step explanation:

There are only two options: right or wrong.

Right for each question: [tex]\frac{1}{2}[/tex]

Since there are 5 questions, and 5 right answers are desired: [tex]\frac{1}{2} * \frac{1}{2} * \frac{1}{2} * \frac{1}{2} * \frac{1}{2}[/tex]

Answer:

triangle on the left: 6 sq ft. triangle on the right: 28 sq ft. rectangle: 128. altogether, 162 sq ft. the trapezoid is about 61.6.

Step-by-step explanation:

for the rectangle the formula is bxh (base x height). for a triangle, it is bxh/2, or base times height divided by 2. for a trapezoid, it is b1+b2 x h / 2, or base 1 (bottom) plus base 2 (top) times height, take all of that and divide by 2.

The equation to represent the temperatures are A = ( -5F ) + ( 13F ) - ( 5F )

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the equation be represented as A

Now , the value of A is

Substituting the values in the equation , we get

Let the initial temperature in the morning be a = -5F

Now , the increase in temperature is b = 13F

And , the decrease in temperature is c = -5F

On simplifying the equation , we get

A = a + b + c

A = ( -5F ) + ( 13F ) - ( 5F )

Therefore , the value of A is  ( -5F ) + ( 13F ) - ( 5F ) = 3F

Hence , the equation is A =  ( -5F ) + ( 13F ) - ( 5F )

Step-by-step explanation:

Let the number of Pots be x.

Number of Buckets be y.

From given data we have,

Customer Bought $1140 worth of 192 poys and Buckets.

Total Items=192

[tex]x + y = 192[/tex] ----------->1

Total Cost=$1140

Cost of each Pot=$5.

Cost of each Bucket=$7

Therefore we get

[tex]5x + 7y = 1140[/tex] --------->2

Solving equations 1 and 2

Equation 2 - 5×(Equation 1)

5x+7y=1140

- 5x+5y=960

-----------------------

0+ 2y=180

-----------------------

2y=180

y=90

From Equation 1 we get,

x+y=192

x+90=192

x=192-90=102

Hence we get

x=102

y=90

Therefore

Number of pots=102

Number of Buckets=90
