The data set below shows prices for concert tickets in 10 major cities. Find the interquartile range (IQR) of the set. How do t

Llana [10]

Answer: IQR = 16

Step-by-step explanation:

Given the following data:

Cost of concert :

CITY : Q, R, S, T, U, V, W, X, Y, Z

Price : 35,36,42,38, 24,29,25, 44,49, 26

Interquartile range (IQR) = Q3 - Q1

Where,

Q3 = the upper quartile

Q1 = lower quartile

Rearranging the data:

24,25,26,29,35,36,38,42,44,49

Q3 = 42

Q1 = 26

IQR = (42 - 26) = 16

How do I evaluate an algebraic expression

xxMikexx [17]

Answer:

To evaluate an algebraic expression, you have to substitute a number for each variable and perform the arithmetic operations. In the example above, the variable x is equal to 6 since 6 + 6 = 12. If we know the value of our variables, we can replace the variables with their values and then evaluate the expression.

Ben is decorating his home with vases of flowers. He bought glass vases that cost $22 each and ceramic vases that cost $14 each.

Ksivusya [100]

Number of glass vases bought = x

Number of ceramic vases = y

Ben bought no more than 10 vases in all.

So total number of vases can be represented as:

$x+y\leq10$

Cost of one glass vase = $22

Cost of x glass vases = 22x

Cost of one ceramic vase = $14

Cost of y ceramic vases = 14y

Total cost of vases is more than $172

So the equation for cost is:

$22x+14y\geq172$

Answer:

So the system of inequalities that can be used are:

$x+y\leq10$

$22x+14y\geq172$

If AABC= A DEF, which congruences are true by CPCTC? Check all that

jolli1 [7]

Answer:

Options A, B and D

Step-by-step explanation:

If the two triangles are congruent, their corresponding parts will be congruent.

If ΔABC ≅ ΔDEF

By the property of CPCTC,

AB ≅ DE

AC ≅ DF

BC ≅ EF

∠A ≅ ∠D

∠C ≅ ∠F

∠B ≅ ∠E

Therefore, Options A, B and D are the correct options.
