Answer:

(B) set B

Step-by-step explanation:

The greatest spread is the range of the given data set.

(A) The given data set is:

84,91,87,77,94,89,74

Arranging the given data in ascending order, we have

77, 77, 84, 87, 89, 91, 94

The range is given as:

$R=94-74=20$

Thus, the spread of the given data is 20.

(B) The given data set is:

89,73,84,91,87,77,94

Arranging the given data in ascending order, we have

73, 77, 84, 87, 89, 91, 94

The range is given as:

$R=94-73=21$

Thus, the spread of the given data is 21.

73,84,89,88,77,91,87,90

Arranging the given data in ascending order, we have

73, 77, 84, 87, 88, 89, 90, 91

The range is given as:

$R=91-73=18$

Thus, the spread of the given data is 18.

(D) The given data set is:

84,89,88,82,91,87,99

Arranging the given data in ascending order, we have

82, 84, 87, 88, 89, 91, 99

The range is given as:

$R=99-82=17$

Thus, the spread of the given data is 17.

Therefore, set B has the greatest spread that is 21.

Without using a calculator, choose the statement that best describes the value of the square root of 46

allochka39001 [22]

Answer:

The value of √46 is between 6.5 and 7.

Step-by-step explanation:

We can use perfect squares to solve this problem.

1² = 1

2² = 4

3² = 9

4² = 16

5² = 25

6² = 36

7² = 49

A square root reverses the squaring operation. Therefore, if we take the square root of 49, we will get 7.

So, because 46 fits in the interval 36 < 46 < 49, we can solve this problem.

√36 = 6

√46 = ?

√49 = 7

Therefore, using this information, we can see that clearly the value of 46 is closer to 49, meaning that the square root of 46 is between 6.5 and 7.
