In the data set shown below, what is the value of the quartiles? {56, 58, 64, 68, 72, 75, 78} A. Q1 = 58; Q2 = 68; Q3 = 73.5 B.
Marysya12 [62]

Answer:

(C) Q1: 55.5 Q2: 110 Q3: 295

Step-by-step explanation:

Given the dataset:

There are 25 items in the dataset.

To find Q2, We divide it into two equal parts and consider the middle term

Therefore: Q2 =110

Q1 = the median of the lower half of the data set.

Q3 = is the median of the upper half of the data set.

In the lower half of the data

Since there are even number of terms,

Median = (55+56)/2=55.5

Therefore: Q1=55.5

In the upper half of the data

Since there are even number of terms,

Median = (239+351)/2=295

Therefore: Q3=295

Q1: 55.5,  Q2: 110,  Q3: 295

The correct option is C.

Serena wants to solve the following system of equations in the most efficient way.
Marianna [84]

Answer:

Serina should have solved for x in the second equation because it has a coefficient of 1.

Step-by-step explanation:

we have

2x+3y=18 ----> equation A

x+7y=31 ---> equation B

we know that

To solve the system of equations in the most efficient way, solve for x equation B and then substitute the value of x in equation A

so

x=31-7y ----> equation C

substitute equation C in equation A

2(31-7y)+3y=18

solve for y

62-14y+3y=18\\11y=62-18\\11y=44\\y=4

Find the  value of x

substitute the value of y in the equation C

x=31-7(4)=3

The solution is (3,4)

therefore

Serina should have solved for x in the second equation because it has a coefficient of 1.
