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:

80 in3

Step-by-step explanation:

12 x 4 = 48 so you divide 48 by 2 which is 24 therefor you take that 10 and multiply it by 24 which is 240, final step you divided 240 by 3 which is 80

Also formated as:

12 x 4 = 48

48/2 = 24

24 x 10 = 240

240/3

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:

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.

Answer:

The circumference should be 84.

The area should be 588.

Step-by-step explanation:

Circumference:

14 × 2 = 28 Multiply the radius by 2 in order to get the diameter.

28 × 3 = 84 Multiply your answer by pi but in this case it's 3 and you have your answer.

Area:

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.

What is an Equation?

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

Answer:

answer is 52 square inches.

Step-by-step explanation:

The formula for surface area for any prism is (2 x Area of base) + (perimeter of base x depth)

1. The base I will choose is the 4 inch by 2 inch side.

We multiply it (4x2) to get 8 then times it by two to complete the first part of the formula:

16 + (perimeter of base x depth)

2. We have to refer to the same base so the 4 x 2 base will have a perimeter of 4 + 2 + 4 + 2 = 12. Then we times by the depth which is 3 in this case.

Thus we have 16 + (12 x 3) =

16 + 36 =

52.

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

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 )
